US President Biden is going to shoot artificial intelligence again!

On the evening of March 7, local time, US President Biden delivered a high-profile State of the Union speech in the election year, which was also his third State of the Union address during his tenure. Biden called on Congress to take urgent action to regulate artificial intelligence through legislation. Biden warned that this technology will bring risks to Americans if it is not controlled.

It is noteworthy that it has been reported recently that the EU is ready to formulate comprehensive artificial intelligence rules or have a global impact.

Look at the detailed report!

Biden made an appeal.

According to CNN quoted by the Global Times, US President Biden delivered a State of the Union speech in the House of Representatives on the 7th local time. In his speech on domestic issues in the United States, Biden called on Congress to take urgent action to regulate artificial intelligence through legislation, including prohibiting "artificial intelligence voice imitation."

Just a few weeks ago, there was an incident of "AI imitating Biden’s phone call" in the United States. The "fake Biden" phone call generated by AI called on 5,000 voters who are most likely to support the Democratic Party not to vote in the New Hampshire primary. CNN subsequently reported that the US government traced and found that 71-year-old man Walter Monk and his Texas-based "Life" company were behind the scenes.

On the 7th, Biden urged legislators to "use the promise of artificial intelligence to protect us from its dangers" and warned that this technology will bring risks to Americans if it is not controlled. However, CNN said that for about a year, American legislators have been working hard to promote any meaningful artificial intelligence legislation. Although false information experts warn of the threat of artificial intelligence to opinion polls and public discourse, few people expect Congress to pass legislation to control the artificial intelligence industry in a divided election year.

At the end of October last year, US President Biden signed an executive order on artificial intelligence, and introduced the first set of White House regulations on generative artificial intelligence. According to the executive order, many government agencies in the United States need to formulate standards to prevent the use of artificial intelligence to design threats such as biological or nuclear weapons, and seek the best method for content verification such as "watermarking" and draw up advanced network security plans. Specifically, the order requires testing artificial intelligence products and reporting the test results to the federal government. It also proposes to attract global artificial intelligence talents to stay in the United States.

The White House said in a statement at the time that the executive order aims to ensure that the United States plays a leading role in fulfilling the promise of artificial intelligence and managing risks. As part of Biden’s comprehensive strategy of responsible innovation, it is based on the actions taken by the President before, including the voluntary commitment of 15 leading companies to promote the safe, reliable and trustworthy development of artificial intelligence.

In addition to artificial intelligence, Biden also mentioned a number of topics in his State of the Union address speech on March 7. In his speech, Biden reiterated that he would not send troops to Ukraine, but at the same time stepped up his appeal for assistance to Ukraine and targeted his Republican rival, former President Trump.

Biden vowed not to send American soldiers to Ukraine, saying that Ukraine wants military aid and weapons to fight back against Russia, not American personnel. "They don’t want American soldiers. In fact, there are no American soldiers fighting in Ukraine. I decided to keep this state. " Biden said. He stepped up his appeal to the United States to continue to provide assistance to Ukraine. Biden said that if the United States ignores Ukraine now, "Ukraine will face danger and Europe will face danger."

In his speech, Biden criticized Trump, who had previously encouraged Russia to "do whatever they want" to NATO countries that failed to fulfill their defense spending obligations. Biden said, "I think this kind of speech is outrageous, dangerous and unacceptable." CNN said that Biden did not directly mention Trump’s name, but called him "my predecessor, the former president of the Republican Party".

On the current Palestinian-Israeli conflict, Biden said that after the attack on October 7 last year, Israel has the right to attack Hamas, but it also has the "basic responsibility" to protect Gaza civilians. He said that he would instruct the US military to lead an urgent task to build a temporary dock on the coast of Gaza to receive a large amount of humanitarian supplies.

Biden also made comments on many issues such as education and economy.

The EU has also made big moves.

It is worth noting that in the field of artificial intelligence, the EU will also make big moves: comprehensive artificial intelligence regulations will be adopted soon.

Recently, foreign media reported that the EU is about to adopt comprehensive artificial intelligence regulations, which are very strict. The European Parliament is scheduled to vote on this legislation on March 13th, and a member of parliament said that he expected the legislation to be passed easily. According to the current timetable, the listing bill will basically take effect in 2026, and some provisions will take effect this year.

The bill will regulate different uses of artificial intelligence according to risks, including banning certain use cases, such as the "emotion recognition" system in the workplace, which will face the highest fine: 7% of global income or 35 million euros, whichever is higher.

The report pointed out that the EU will not be the first jurisdiction to regulate artificial intelligence, but the size of the European market means that the EU Artificial Intelligence Act will be affected globally, affecting the way multinational companies manage data and use artificial intelligence. The law will apply to enterprises operating in the markets of 27 countries and builders of artificial intelligence systems used by the European Union headquartered anywhere, including the United States.

In the United States, legislators also discussed artificial intelligence supervision, held industry hearings, and introduced bills. However, Congress has not yet passed legislation to widely regulate the use of this technology.

Frequent explosion models in the industry

At present, for artificial intelligence with great potential, regulatory legislation is one aspect, and development is also a very important aspect.

Recently, Sora detonated a new round of AI arms race, and the era of general artificial intelligence accelerated. In mid-February, Google released Gemini 1.5 Pro, which enhanced its ability to handle a large number of videos, texts and images. Developers can submit up to 1 million tokens to Gemini 1.5 Pro, which is equivalent to about 1 hour of video, 11 hours of audio or 700,000 words of text data.

Immediately, OpenAI released the Wensheng video model Sora, which can generate high-definition smooth video up to 60 seconds with text instructions, and has significant advantages in generating video length, coherence and multi-shot switching. Compared with the previous Wensheng video models Runway, ika and Stable Video, it has achieved cross-generation upgrade.

Galaxy Securities believes that the iterative speed of overseas technology giants to upgrade multimodal large models far exceeds expectations, Sora can simulate actions that affect the state of the world in a simple way, and the era of general artificial intelligence may come ahead of schedule. The broker further pointed out that multi-modal scenarios such as Sora and Gemini will broaden the downstream application scenarios, which will provide new production tools for movies, advertisements, games, short videos and other fields, and related industries are expected to reduce costs and increase efficiency and take the lead in application.

Sora’s powerful Wensheng video capability will rapidly promote the commercialization of the application end, stimulate the industrial scale, and then transmit it to the upstream computing infrastructure, and the demand for computing infrastructure will once again erupt. According to the calculation, Sora’s demand for computing power at the reasoning end will increase exponentially, which will drive the demand for infrastructure such as upstream chips, servers, optical modules and liquid cooling.

In addition, on March 5th, Anthropic released a new generation of AI big model series -Claude 3. There are three models in this series, which rank from weak to strong: Claude 3 Haiku, Claude 3Sonnet and Claude 3 Opus. Claude3 Opus has surpassed GPT-4 and Gemini 1.0 Ultra in many evaluation benchmarks, showing strong computing power in many fields, and further promoting the benchmark of artificial intelligence big model industry. Guolian Securities said that the Claude3 model was released, and the development of artificial intelligence continued to be interpreted, focusing on the three main lines of computing power, model and application.

Dongxing Securities said that the current artificial intelligence industry support policies and explosion models are frequent. As one of the engines of new productivity, artificial intelligence may promote the upgrading of traditional industries, and it will continue to make breakthroughs in the application side under the background of digital industrialization and industrial digital development. At the same time, it will benefit from the dimensions of data and landing in education, medical care, law and other fields. At the same time, the development of multi-modal and the release of new models will bring about the improvement of computing power demand and the pattern change on the model side. Model companies and application companies are expected to benefit from the development of the industry.

In the secondary market, artificial intelligence concept stocks continue to be active. On March 7th, in the US stock market, NVIDIA, the global leading AI computing enterprise, rose by more than 4%, reaching a new high for six consecutive trading days, with a market value close to 2.3 trillion US dollars, less than 300 billion US dollars from Apple’s closing market value. In the A-share market, on March 8, Industrial Fulian, Gaohong, Shengtong, and CLP Xingfa had daily limit.

CCTV News:On the afternoon of January 18th, the Ministry of Commerce held a regular press conference. According to the spokesperson, the "2024 National Online New Year Festival" kicked off on January 18 and the event will last until February 17.

According to the Ministry of Commerce, digital, healthy and green are the new trends of consumption, and they are also the main new ideas of local activities. Around digital consumption, Beijing and other places held the first show of computer, communication and consumer electronic products, the "Science and Technology New Year Festival" and other activities. Around healthy consumption, Shanghai and other places hold "super holidays" and other activities in response to the seasonal demand in winter. Around green consumption, all localities have guided e-commerce enterprises to strengthen the supply of "small dishes", issued green packaging initiatives, and advocated a green and environmentally friendly lifestyle.

He Yadong, spokesman of the Ministry of Commerce:Closely following the needs of the New Year Festival, we will carry out three major "Spring Festival Rejuvenation" promotional activities. Around the rejuvenation of the home, Tianjin and other places carried out activities such as live broadcast of furniture and home appliances and special sales subsidies. Around the rejuvenation of the national tide, Zhejiang and other places carried out activities such as the "Non-legacy New Year Festival" and launched more domestic "tidal products". Around the scene rejuvenation, Shaanxi and other places carried out activities such as "Night Chang ‘an Chao Chang ‘an" to enhance the consumer experience in all aspects.

National Development and Reform Commission: Launching the "Consumer Help for the Spring Festival Action" in 2024

The National Development and Reform Commission (NDRC) recently launched the "Consumer Assistance for the New Year Action" in 2024, mobilizing and calling on organs at all levels, enterprises and institutions, social organizations and the general public to actively participate in holiday consumption assistance, and actively purchasing various products and cultural tourism services in underdeveloped areas such as poverty-stricken areas under the premise of fully respecting market rules.

In 2024, in the "Action of Consumption Helping the Spring Festival", all relevant regions and departments should increase the consumption and purchase of characteristic agricultural products in underdeveloped areas such as poverty-stricken areas, encourage them to go to poverty-stricken areas to carry out county-level cultural tourism consumption, and continue to strengthen the sales and assistance of products and services in poverty-stricken areas, especially in "three districts and three States", key counties for national rural revitalization, and relocation and resettlement areas.

Do a good job in organizing the supply of characteristic agricultural products in underdeveloped areas, smooth the passage from mountain to city, strengthen the control of product quality, and further increase the proportion of market-oriented help and sales.

In 2022 and 2023, in the "Consumer Help the Spring Festival Action", the total amount of sales assistance from various regions and departments reached 170 billion yuan, which effectively improved the income level of people out of poverty, promoted the development of characteristic industries and product upgrading in underdeveloped areas, and promoted the sustained recovery and expansion of domestic consumption.

Ministry of Culture and Tourism: Carry out the cultural tourism activities of "Happy New Year" throughout the country.

The reporter learned from the Ministry of Culture and Tourism on January 18th that during the Spring Festival, the Ministry of Culture and Tourism will organize the theme cultural and tourism activities of "Happy New Year" in 2024. The activities cover many fields such as Huimin’s cultural performances, intangible experience display, tourism and leisure consumption, and enrich people’s holiday life.

It is understood that the theme culture and tourism activities of the 2024 Spring Festival of "Happy New Year" were carried out from January 18 to March 11. This activity covers many fields such as public service activities, non-legacy experience display, tourism and leisure consumption, ice and snow research and tourism.

The theme activity of "Colorful Study Tour to China" is jointly participated by 11 provinces including Yunnan, Shandong, Zhejiang, Anhui and Jiangxi. Yunnan will launch a series of research activities such as "exploring biodiversity"; Jiangxi will launch the activity of "Traveling with Poetry in Jiangxi"; Protecting the beautiful Yangtze River theme research tourism activities, with the participation of provinces along the main stream of the Yangtze River; Shanghai will launch a "century-old civilization, butterfly changes into a new life — — Industrial research opens the next wonderful event; Hubei will launch a series of research theme activities such as "telling the epic of the red soul" and "welcoming the New Year without leaving behind"; The "ice and snow theme research tourism activities" are mainly concentrated in Heilongjiang and Jilin.

In addition, during the Spring Festival, the Ministry of Culture and Tourism will also launch the "100 Cities and 100 Districts" financial support consumption action plan, covering the whole chain of "eating, living, traveling, buying and entertaining", so that people can benefit and enterprises can really benefit.

　　BEIJING, Beijing, May 17 (Zhongqing) Following Beijing, hot cities such as Guangzhou, Shanghai and Shenzhen have successively introduced property market regulation measures for commercial projects. Although the intensity of control is different, it is clear that commercial projects should not be linked to residential properties, and some cities have also explored control methods in architecture and design, trying to reduce the possibility of commercial projects turning to residential uses from the product development end.

　　After Beijing, Shanghai, Shenzhen and other places followed up to regulate the commercial market.

　　On March 26th, Beijing Municipal Commission of Housing and Urban-Rural Development issued a document to regulate the commercial market, saying that "commercial and office projects (hereinafter referred to as commercial projects) should be developed, constructed, sold and used in strict accordance with the planned purposes, and may not be changed to residential purposes without approval", completely changing the rules of the commercial market.

　　The above-mentioned policies in Beijing not only block the channels for individuals to buy projects that have not been built, are under construction or are being sold, but also set strict thresholds for individuals to buy second-hand commercial houses.

　　Four days later, Guangzhou proposed to strengthen the management of commercial real estate projects. "Real estate development enterprise vendors do property, the sales target should be a legal entity; The commercial property purchased by a legal entity shall not be used as a residence, and when it is transferred again, it shall be transferred to the legal entity. "

　　On April 21st, many departments in Chengdu jointly issued the Notice on Further Strengthening the Management of Commercial and Office Construction Projects, requiring commercial and office construction projects to be developed, constructed, sold and used in strict accordance with the nature of planned land and planning permission, and it is strictly forbidden to change them into residential purposes without authorization.

　　On the same day, Shanghai required that the land transfer contract should specify that office land should not be used for apartment-style office projects, and commercial land should not be used for apartment-style hotels without agreement.

　　On May 12th, Shenzhen also issued a document to restrict the transformation of commercial offices. In the next five years, the transformation of commercial offices, R&D buildings into apartments, stealing areas and rebuilding will be strictly restricted. "After the introduction of the New Deal, such facilities will serve more office needs, that is, they are unlikely to serve the needs of housing." Yan Yuejin, research director of the think tank center of Yiju Research Institute, said that this has a negative effect on the subsequent Shenzhen commercial projects.

　　So far, Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu and other cities have implemented control policies for commercial projects. From the perspective of urban types, they are basically concentrated in first-tier cities and some hot-spot second-tier cities.

　　Product design of multi-city document management and control returning to commercial attributes

　　No matter from the length of policy content, release time and follow-up supporting measures, Beijing has the strictest control over commercial projects.

　　"In the more than one month after March 26th, the actual transaction in the commercial market in Beijing fell sharply." Zhang Dawei, chief analyst of Zhongyuan Real Estate, bluntly said that it is the strictest commercial purchase restriction policy in history, which has dealt a significant blow to the overheated commercial market.

　　According to the policy of multi-site business regulation, it is a basic principle not to change it to residential use without authorization. For real estate development enterprises that change commercial real estate projects into residential purposes in violation of the plan, they all take a firm attitude of "once verified and dealt with seriously".

　　On the other hand, there are also differences in the intensity of regulation. Except for Beijing, other cities have not explicitly restricted individual commercial loan purchasers from running projects. Shenzhen, Chengdu and other places focus on product design control at the supply end.

　　For the development enterprises, the minimum division unit of newly-reported commercial projects is strictly regulated as not less than 500 square meters in Beijing, not less than 300 square meters in Guangzhou, and only part of the proportion is required in Shenzhen. In terms of transfer, Beijing and Guangzhou stipulate that purchased commercial properties can be transferred to legal entities and individuals, but Guangzhou has set "additional conditions" for the transfer, that is, individuals can not transfer again until they have obtained the immovable property certificate for two years.

　　Why is it limited? Crack down on speculation and limit the influx of people

　　"The activity of commercial projects is mainly due to the restriction on the purchase of houses and the high-end of houses, so a large number of public buildings are supported in the residential land." Speaking of the heat of the commercial market, Zhang Dawei believes that it has something to do with the increase in population.

　　Zhang Dawei said that in first-tier cities such as Beijing and Shanghai, the demand for permanent residents’ housing is huge. Some projects in the name of commerce, hotels and offices, by dividing property rights, change the use attributes of commercial projects, take "quasi-housing" as a selling point, and play a marginal role in electricity and water use to attract buyers.

　　However, due to the different nature of land use, there are obvious differences between commercial projects and commercial housing. First of all, the property right is 40 or 50 years, and there is no residential facilities (school district houses, etc.), with high residential density and small apartment type; The most important thing is that the house price will be lowered by 50-60% compared with the price of commercial housing in the same region.

　　"Low housing prices and no purchase restrictions are the main reasons for choosing commercial projects." Many interviewees who have purchased commercial projects told the reporter of Zhongxin. com.

　　Why should we regulate the commercial market? "The first is the planning problem. The business that is originally a residential facility has the property of residence, which is contrary to the planning and the related facilities cannot be followed up; The other is the population problem, such as the large population of commercial projects in Beijing and Shenzhen; In addition, due to the low land price of commercial land, developers take land with commercial land but sell it at residential prices, earning extra profits in disguise. " Zhang Dawei said.

　　Hua Zheng, an associate professor in the Department of Land Management, School of Public Administration, Renmin University of China, pointed out in an interview with the media that commercial regulation will ensure that residential houses and commercial offices belong to commercial offices, reduce the customer base of commercial properties, reduce the enthusiasm of developers and investors to run products, and then reduce the premium level of commercial land. "Cracking down on speculation in the commercial market will also limit the disorderly influx of population into big cities to a certain extent".

　　It’s not over! More cities may be planning to standardize the business market.

　　"There are cities that are brewing or starting to set off a new round of blockades ‘ Business changes to residence ’ 、‘ Do change and live ’ The policy tide. " Zhang Dawei predicted that before, the investment demand for buying commercial projects due to residential purchase restriction may face great risks.

　　Yan Yuejin, who predicted that Shenzhen and Shanghai would follow up the regulation of commercial projects, told reporters that in the future, some hot cities will actively follow up the purchase restriction of commercial projects. Although the intensity of control will not be equal to that of Beijing, one thing is certain: "Commercial projects are no longer linked to residential properties."

　　In Yan Yuejin’s view, in terms of policy strength, the measures to directly restrict or prohibit sales represented by Beijing are the most severe, and the control effect is the most obvious; However, the following mainstream model may be to standardize the supply side and actively control product design.

　　"Beijing and Guangzhou will not rule out the formulation of new policies for existing properties, for example, reasonable guidance for some buyers who sell and transfer houses." Some insiders analyzed to reporters. (End)

Review: Hu Bijie and Pan Jue

First, a brief introduction to medical history

Male, 63 years old, from Shanghai, was admitted to the Infectious Diseases Department of Zhongshan Hospital for the second time on November 23, 2022.

Chief complaint: indwelling catheterization with repeated urine color turbidity for 2 months and then 8 days.

Current medical history:

On September 19, 2022, I went to a hospital in Shanghai for fatigue, anorexia and dysuria. WBC 10.12×10 9/L, N 87.6%, Hb 53g/L, hsCRP 135.22mg/L, ESR 62mm/H, albumin 30.1g/L, Scr 589μmol/L, K 2 were examined. Urine routine: WBC 3892/ul, occult blood 3+/RBC 5579/ul, protein 2+; Chest CT: bilateral pleural effusion, partial atelectasis of lower lobe of both lungs; Abdominal pelvic CT: Bilateral middle and upper ureteral dilatation and renal pelvis and calyceal dilatation, the patch in the right part of calyceal is slightly high density, the bladder wall is thickened, there is a little flocculent blur around the left renal fat sac and ileocecal part, and there is a little effusion in the pelvic cavity. A large amount of turbid urine was drained by indwelling catheter. Urine culture showed that Klebsiella pneumoniae was positive. Considering urinary tract infection, acute kidney injury, hypokalemia and severe anemia, patients were given symptomatic support treatment such as anti-infection, bladder irrigation, antioxidation, potassium supplementation and blood transfusion. The symptoms of patients improved and the urine was slightly clarified. 10-18 Review urine routine: WBC3+, RBC3+, protein 1+, SCR 263 μ mol/L.

I was admitted to our department on October 19, 2022. Blood routine: WBC 5.08X10 9/L, N 66.1%, inflammatory markers: ESR 19mm/H, hsCRP 52.3mg/L, PCT 0.52ng/ml, Scr 257μmol/L, and urine routine: WBC 28493/μ. Urinary color Doppler ultrasound: hydronephrosis, bilateral ureteral dilatation, bladder wall thickening significantly; Abdominal pelvic CT: hydronephrosis of both renal pelvis and ureter, thickening of ureter wall (inflammatory change), inflammatory change of bladder and ureter may be large, the volume of both kidneys increases and the substance is thin. Meropenem 1g q12h is given for empirical anti-infection. Urology consultation considers the acute stage of infection, so it is not suitable to put double J tubes. If necessary, pyelostomy can be done, but it does not improve renal function much. Bladder irrigation is recommended. 10-20 middle-stage urine culture (sampling on October 19): Klebsiella pneumoniae was positive; 10-22 urine culture drug sensitivity: Carbapenem-resistant Klebsiella pneumoniae (CRKP), adjusted to ceftazidime and abamectin 2.5g q12h for anti-infection, and daily bladder irrigation. After treatment, the urine color of the patients gradually became clear, and the urine white blood cell and bacterial count gradually decreased during follow-up. The urine bacterial culture was negative on November 1 and November 4. Check the urine routine on November 09: WBC 28/uL, RBC 4/uL, urine protein+,bacterial count 29/UL;Blood WBC 7.64×10 9/L, N 76.5%, hs-CRP 0.4mg/L, ESR 25mm/H, PCT 0.18ng/mL, Scr 175μmol/L, which were significantly improved compared with those at admission. Stop ceftazidime and abamectin on November 11 and be discharged.

On November 15, 2022, the patient appeared turbid urine again, and there was no fever and other discomfort. On November 23, he was admitted to the hospital for a second diagnosis and treatment.

Past history: In September, 1991, T12-L1 comminuted fracture was treated with internal fixation. After operation, the catheter was retained for half a year due to urinary incontinence, and then the catheter was removed after urination. There was no urinary tract infection during this period. Diabetes for 16 years, insulin therapy, blood sugar control can be; Hypertension for 5 years, oral amlodipine to reduce blood pressure, blood pressure control can be.

Second, the admission examination (admitted on November 23, 2022)

[physical examination]

T: 36.2℃ P: 90 times/min R: 20 times/min BP: 176/105 mmHg.

Stay in bed, feel refreshed and calm, lose weight, and muscle atrophy of lower limbs; Breathing sounds in both lungs are thick, and dry and wet rales are not heard; The rhythm of the heart is regular, the abdomen is soft, without tenderness and rebound pain, without mass, without percussion pain in both kidneys, without tenderness at ureter point and rib and waist point, and the lower abdomen does not touch the enlarged bladder. During indwelling catheterization, the urine in the urine collection bag is turbid and more white flocs are deposited. Limbs are not swollen.

[Laboratory examination]

Blood routine: WBC 7.85×10 9/L, N 81.3%, HB 121g/L, PLT 170×10 9/L.

Urine routine: WBC 2775/μ l; RBC 2/μl, bacterial count: 39879/μl, nitrite positive, leukocyte esterase+++.

Inflammation markers: hs-CRP 17.9mg/L, ESR 68mm/H, PCT 0.12ng/mL.

Biochemistry: ALT/AST 23/21U/L, Alb 47g/L, Scr 199μmol/L, eGFR 30ml/min/1.73m2, na/k 140/5.5mmol/l.

Third, clinical analysis

Characteristics of medical history: middle-aged and elderly male, indwelling catheter, with repeated urinary turbidity and abnormal urine routine. Urine culture showed CRKP one month ago, and it improved after ceftazidime-ababactam treatment, but urine turbidity reappeared three days after drug withdrawal, blood inflammatory index increased, urinary leukocyte and bacterial count increased significantly, and the diagnosis of urinary tract infection was clear. The reasons for short-term recurrence after antibacterial drug treatment improved were considered:

Recurrence of CRKP infection: The patient has been indwelling catheter for 2 months, and there may be biofilm formation of catheter and abnormal urinary tract structure, which makes it difficult to completely eliminate the infection and relapse after stopping taking the drug. Therefore, urine culture and drug sensitivity test can be improved.

New infection: the patient has high risk factors of recurrent urinary tract infection, and the pathogen may be different each time. The patient’s previous CRKP infection treatment was effective, and the possibility of new pathogen infection should be considered in the short term, until the urine culture is perfect and clear.

Multiple infections: patients with abnormal urinary tract structure, indwelling catheter and other risk factors can not be removed, so it is necessary to be alert to the possibility of multiple pathogens including fungi combined with infection, repeat the cultivation of urine bacteria, mycoplasma, fungi and mycobacteria, and improve urine mNGS to help clarify the infected pathogens.

Four, further examination, diagnosis and treatment process and treatment response

On November 23, 2022, the middle urine smear was used to find bacteria: moderate amount of G- bacilli, and continued ceftazidime and abamectin 2.5g q12h ivgtt for anti-infection and bladder irrigation.

On November 26, 2022, the bacterial drug sensitivity of the middle-stage urine culture (sampling on November 23) was CRKP, ≥ 100,000 /ml, and urine mNGS: a large number of Klebsiella pneumoniae (species strict sequence number: 406,866) was detected.

On November 29, 2022, the abdominal and pelvic CT was reexamined: bilateral dilated hydronephrosis accompanied with inflammatory changes of ureter, and the parenchyma of both kidneys was thin, and the inflammatory changes of cystitis might be larger, similar to that of 22-10-20 slices.

November 30, 2022 (sampling on November 29): Enterococcus faecalis was positive. On December 2, according to the drug sensitivity, fosfomycin 3g qod was added orally, and ceftazidime and abamectin were suspended.

Repeated urine cultures on March, April and June, December, 2022: Enterococcus faecalis was positive and CRKP was negative.

On December 8, 2022, the urine WBC was 38738/μ L, and the bacterial count was 43285/μ L; Urine culture: CRKP positive, Enterococcus faecalis negative.

Phage therapy was carried out from the afternoon of December August, 2022: Phage cocktail (composed of 5 strains of Klebsiella pneumoniae phages A103KP172, A106KP176, A121KP192, A49KP106 and A58KP118, 5mL each), injected with 225mL physiological saline (according to the estimated bladder volume), and the total volume was 250mL, and then the catheter was clamped.

Urine routine on the third day of phage treatment on December 11, 2022: white blood cell count: 235/uL, bacterial count: 722/uL；; Urine bacterial culture was negative.

Urine routine on the 5th day of phage therapy on December 13th, 2022: white blood cell count: 279/uL, bacterial count: 92/ul; Urine bacterial culture was negative; Blood WBC 6.35X109/L, N 70%, hs-CRP 0.9mg/L, ESR 26mm/H, and inflammatory index decreased compared with before; Re-examination of urinary color ultrasound showed that bilateral renal pelvis separation and upper ureteral dilatation were better than before (10-20), and the thickness of bladder wall was reduced (12-25mm→13mm).

He was discharged from hospital on December 14, 2022 for follow-up.

V. Final diagnosis and diagnosis basis

Final diagnosis:

Complex urinary tract infection (CRKP, Enterococcus faecalis)

Neurogenic bladder, hydronephrosis and hydroureter (indwelling catheter)

Renal insufficiency

Diagnostic basis:

The patient is a middle-aged and elderly male with neurogenic bladder caused by paraplegia, indwelling catheter, turbid urine with flocs, increased CRP and PCT, significantly increased WBC and bacterial count in urine, repeated CRKP positive in urine culture, positive in enterococcus faecalis, abdominal basin CT: hydronephrosis of renal pelvis and ureter, anti-infection, normal inflammatory markers and urine routine after phage treatment, clear urine and negative urine culture, so complicated urinary tract infection.

The patient suffered from anorexia and dysuria, and the serum creatinine increased obviously. Abdominal CT showed that both kidneys were enlarged, the cortex was thin, and bilateral urinary tract was hydronephrosis. After active treatment such as controlling infection and improving renal function, the serum creatinine decreased, so the diagnosis of renal insufficiency was clear.

Six, experience and experience

Phage is a targeted sterilization virus in nature and a sterilization star in the "pre-antibiotic era". Phage therapy has a history of more than 100 years, but the discovery and application of broad-spectrum antibiotics have gradually marginalized it. With the increasingly serious problem of bacterial drug resistance, phages have once again received attention and become the most promising supplement and alternative therapy for treating superbugs. The clinical application of phage in China is relatively late, but it has developed rapidly in recent years. In 2017, the Shanghai Institute of Phage and Drug Resistance was established, with Professor Hu Bijie as an academic member. Since 2018, the institute has carried out the first clinical trial of phage therapy in China. At present, it has treated nearly 100 patients with drug-resistant bacterial infections from all over the country and accumulated rich clinical experience in phage therapy, which is a leading position in the field of clinical phage therapy in China.

Phage has many advantages, such as host bacteria dependence, targeted specific sterilization, no infection to eukaryotic cells (little influence on normal flora), no influence on bacterial drug resistance, synergy with antibacterial drugs, penetration of biofilm and so on. The cure rate of acute bacterial infection is high, and the therapeutic effect of chronic bacterial infection is no less than that of antibacterial drugs, and the safety of phage treatment is also extremely high. A systematic retrospective study showed that the vast majority of patients who received phage therapy had no or only slight adverse reactions, 86.7% patients’ clinical symptoms improved, and 78.8% patients achieved the eradication of pathogenic bacteria. Our clinical trials also show that more than 70% of patients have achieved good therapeutic effects, and there are no obvious cases of adverse reactions. This patient was repeatedly infected with Klebsiella pneumoniae due to long-term paraplegia, abnormal urinary tract structure, indwelling catheter and other factors. The diagnosis of complicated urinary tract infection was unquestionable, and the choice of antibacterial drugs was limited due to multi-drug resistance and renal insufficiency. Phage therapy is very suitable.

The disadvantages of phage therapy include narrow host spectrum, individualized plan (it is difficult to treat empirically), no unified standard for the best treatment decision, and rapid tolerance. Phage cocktails, combined antibacterial drugs and multiple treatments are usually used in clinic to improve the curative effect. At present, the targeted pathogens of phage therapy in our team mainly include: multi-drug resistant Gram-negative bacteria (Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli) and Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecalis); Covering respiratory system, urinary system, abdominal cavity, bones and joints, skin and soft tissue and other infected sites; Treatment depends on the site of infection, and intravenous application of phage is still being explored. In this case, the patient didn’t have percutaneous nephrostomy because of the little clinical benefit, so he was treated by transurethral bladder perfusion, and the phage could not cover the whole urinary tract evenly. Although the pathogen turned negative in a short period of time and was well tolerated, its long-term curative effect may not be good, and it needs repeated phage treatment.

Phage therapy has huge clinical demand and broad market. In recent years, our team has focused on the clinical application (treatment and prevention and control of nosocomial infection) and basic research of phage therapy, with a view to becoming a powerful weapon to curb drug-resistant bacteria in the future.

? ? Huawei’s every move in the mobile phone industry has attracted widespread attention in the industry. Today, Huawei’s senior executive Yu Chengdong officially announced that the Huawei Mate 70 series will be officially released in mid-November. I believe this news will definitely arouse the expectations of countless technology enthusiasts. Yu Chengdong also said on social media: "The most powerful Mate in history! See you in November!" This not only indicates the imminent arrival of the Mate 70 series, but also shows that this new machine may bring disruptive innovation.

? ? It is reported that the Mate 70 series will include four models: Mate 70, Mate 70 Pro, Mate 70 Pro + and Mate 70 RS Extraordinary Master. According to early revelations, these models will continue the classic style of the Mate 60 series in appearance design, with a three-hole screen design on the front and support for 3D facial recognition. In addition, the new series will also introduce side fingerprint recognition to further enhance the user’s unlocking experience.

? ? There are even netizens who have produced corresponding Mate 70 product rendering graphs and some promotional materials.

? ? Another highlight of Huawei’s Mate 70 series is the new native Hongmeng system. This system is Huawei’s self-developed operating system, which aims to achieve a higher degree of autonomy and control. Yu Chengdong has said that after a decade of hard work, Huawei has achieved a breakthrough in the core technology of the operating system, and the launch of Hongmeng system marks another milestone in Huawei’s software ecosystem construction.

? ? According to the revelation, the Mate 70 series will no longer be compatible with Android-developed applications and will only support Hongmeng native applications. This strategy will undoubtedly promote the development of Hongmeng’s ecosystem, but also raise users’ expectations for the new system.

? ? In terms of appearance design, the Mate 70 series will cancel the previous dual-screen color scheme and use the rear camera area of the large round module, which will return to the consistency with the Mate 50 series. It is worth mentioning that the rear main camera will be equipped with the domestic outsole sensor customized by Howell, with a large variable aperture to ensure high-quality photos under different lighting conditions. The screen of the Mate 70 series will use 1.5K OLED technology, with the screen shape of equal depth and four curves, making the whole machine more delicate and elegant in visual effect. Its four-sided and equal-width design also makes the overall look and feel more harmonious.

? ? In terms of hardware, the Mate 70 series will be equipped with the latest Kirin processor, which will significantly improve performance. In terms of battery life, the series of mobile phones will be equipped with a new silicon anode battery with a capacity between 5000 and 6000mAh, further extending the service life and meeting the high demand of users.

? ? At the same time, Huawei’s Mate 70 series has begun to distribute equipment to offline dealers, but Huawei’s confidentiality measures for new products are still very strict. The relevant warning sign clearly states: "Before the conference, unauthorized opening is prohibited, and the fine for unpacking in advance is 500,000 yuan."

Mortal hero 　　When Bruce Lee was a child, his physique was weaker than that of ordinary people, and he still had physical defects-long and short legs (one inch apart), big myopia (1,000 degrees) and short stature (1.73 meters). However, under such congenital conditions, Bruce Lee not only practiced a shocking martial arts, but also created his own Jeet Kune Do, and eventually became a generation of martial arts masters. Whether hard-working or intelligent, Bruce Lee’s life is a legend, from an ordinary person to an "altar". 　　Bruce Lee has become a spiritual idol of modern people, not only because of his superb martial arts, but also because of his "self-esteem". In the commercial world with a strong smell of Hollywood powder, he conquered the world by his own flying, kicking and punching. In his short acting career, he never used body double once. People can still remember his famous saying: "I am a martial artist first, then an actor." Dragon power one Hit a heavy fist of 159 kilograms with a weight of 62 kilograms 2 Hit 726 kilograms with nunchakus. three Kick a strong man in armor 20 meters away. four Extend and retract the straight arm of the 34 kg barbell horizontally, and hold it for 20 seconds after extending. five Easily insert your finger into an unopened can of Coca Cola. six Kick a 45 kg sandbag with a side kick. seven Kick about 135 kilograms of sacks to the ceiling height.

Dragon lore Jeet Kune Do 　　Jeet Kune Do is an all-round free fighting technique created by Bruce Lee, which combines the essence of various martial arts in the world. "Jeet Kune Do" means the way to stop an opponent from punching, or the way to intercept an opponent to punch. It is the program and essence of Jeet Kune Do that "taking the impossible as the law and infinity as the limit". 　　Comments on Jeet Kune Do by World Masters 　　American karate champion Lewis Deere told the American Black Belt magazine: "I can’t meet another person who is as crazy about martial arts as Bruce Lee. He can succeed because he is willing to work hard except for half of his talent. He really works very hard. The origin is fast, accurate and energetic enough to make him look at the martial arts arena. In addition, his knowledge and proficiency in various martial arts instruments can be called an expert, but no one can match him. "　 　　Purpose of Jeet Kune Do training:　 　　1. Destroy the enemy facing you-remove the obstacles to freedom, justice and humanity; 　　2. Destroy anything that bothers your mind, without hurting people, but you can overcome your greed, anger and ignorance. Dragon Juesha nunchaku 　　During Bruce Lee’s stay in the United States, he learned nunchakus and Filipino nunchakus from Dan Enosando, a famous American Filipino nunchakus and nunchakus, who was also a teacher, friend and apprentice. Under his guidance, he learned nunchakus and nunchakus and became an expert in using sticks. 　　Bruce Lee used nunchakus for the first time in the Hollywood drama The Green Hornet. Nunchakus are two round hardwood sections, which are connected by chains or pimps. They can be slammed and strangled, combining the rigidity of the stick with the femininity of the whip. An American martial arts monograph once introduced: "One end of a waving nunchakus can produce a force of 1,600 pounds, while a human bone can be crushed with only eight and a half pounds of force. Bruce Lee nunchakus performs, and once the chain or pimp connecting nunchakus is wrapped around each other’s neck, it is enough to hang people with a gentle pull. " Bruce Lee often carries nunchakus for self-defense. 　　Now, many states in the United States prohibit the use and possession of nunchakus by law. The reason is that some young Americans have seen Bruce Lee’s Kung Fu movies, or heard about the power of nunchakus, and they have also played with nunchakus, resulting in human lives and being condemned by public opinion. Dragon Juesha Cunquan 　　Bruce Lee Invincible Inch Boxing evolved from Wing Chun’s Inch Strength Boxing, which is a particularly advanced killer skill in Jeet Kune Do. Bruce Lee’s "inch fist" can hit a person who weighs more than 75 kilograms several meters away. 　　Wing Chun Boxing has a special way of exerting strength, which is called inch strength. The so-called inch strength refers to the short, brittle explosive force that suddenly accelerates the contraction of muscles when it is very close to the target or when the action is about to be completed. In the wing wing gate, the wing wing master can launch a continuous and compact attack without gaining momentum, and knock down the opponent at a distance of 1 to 3 inches or even in a close-fitting state. According to the principle of mechanics, the force produced by an object after acceleration is the greatest. Therefore, if the strength of a fist is large, it must also be slammed after bending the arm to ensure that there is enough distance to accelerate. The inch strength is the opposite, requiring a large force in the shortest distance. 　　After the founding of the People’s Republic of China, the state advocated "martial arts fitness", and many sects further promoted "martial arts to get rid of diseases", which attracted a large number of patients to join the ranks of martial arts. However, they passed on martial arts to the younger generation, which made a lot of self-defense techniques lost. This historical lesson is worth reflecting on …

Dragon journey 　　Bruce Lee was born in San Francisco, USA, and spent his childhood and adolescence in Hongkong. Bruce Lee was very thin when he was young. His father taught his son to practice Tai Ji Chuan when he was 7 years old for his strong physique. At the age of 13, Bruce Lee systematically studied Wing Chun Boxing with the famous teacher Ye Wen, and set up a wooden stake at home, practicing against it every day. In addition, he also practiced Hongquan, Baihe Boxing, Tan Leg, Shaolin Boxing, Poke Foot and other boxing styles, which laid a solid foundation for later creating Jeet Kune Do. 　　In order to improve the level of martial arts, Bruce Lee not only studied China’s boxing, but also studied western boxing. While attending western boxing training classes, he saved his pocket money to buy a documentary about the boxing match of Louis, the world champion, from which he learned the footwork, posture, boxing and training methods of the champion. He also often participates in boxing competitions inside and outside the school, constantly enriching his actual combat experience. 　　Go to the United States for further study and create Jeet Kune Do. 　　Fearing that Bruce Lee would fail in school, at the age of 18, Bruce Lee’s parents decided to send Bruce Lee to study in the United States. Bruce Lee’s life in Seattle is quite hard. After he entered the university, he devoted all his energy to studying martial arts besides studying. He organized a "China Kung Fu Team" at school, and often conducted training and performances on campus, which won the praise of teachers and students. 　　Bruce Lee gradually became proficient in Kung Fu and even reached a higher level through continuous improvement. Among them, "Li Sanjiao", "Inch Fist" and "Hooking Hands" are his unique skills. Bruce Lee is a generalist. Besides mastering all kinds of boxing, he is also good at various instruments such as long sticks, short sticks and nunchakus, and he also studies Qigong and hard work. 　　In order to promote Chinese martial arts, Bruce Lee rented a corner of a parking lot on campus during his sophomore year, and put up the brand of "Zhenfan National Art Museum". He practiced while teaching and worked hard, and his skills improved greatly, especially his leg skills. In the Zhenfan National Art Museum, he met Linda, a female medical student who came to study martial arts. After more than a year of communication, they gradually developed feelings. In August 1964, they officially got married. After their marriage, Bruce Lee and his wife both dropped out of school and joined forces to run a martial arts school. 　　Since the news that Bruce Lee subdued four knife-wielding gangsters in Chinatown, Florida, and bravely saved Chinese girls was published in the newspaper, Bruce Lee’s name has spread all over the United States, and TV stations such as Florida have also asked him to perform leg skills, and China Kung Fu has attracted people’s attention. And the museum of Zhen Fan Guo Shu, which he founded, has gradually flourished. In order to expand his influence, Bruce Lee often participated in martial arts competitions everywhere, and successively opened martial arts branches and apprentices in Seattle, Oakland and Los Angeles. The scale and equipment of the martial arts museum are constantly improving, and many prominent martial arts stars in the world, such as American karate champion Rolex, are vying to worship him as a teacher, and famous Hollywood movie stars such as James Hempin and Steve are his disciples. Ali, the world champion, also paid a visit to exchange experiences with him. Boxers of various schools in the United States often gather in the martial arts school in Bruce Lee to discuss martial arts, and his aim of "making friends with martial arts" has achieved the expected results. 　　Set foot in the film industry, kung fu shocked the world. 　　In the early 1970s, a wave of China Kung Fu movies swept the world. The resounding name of Bruce Lee shocked the whole world. 　　In the summer of 1971, Bruce Lee accepted the invitation of Hong Kong Golden Harvest Film Company, and signed two films for 15,000 US dollars. The first film was "Tangshan Big Brother" with the theme of China martial arts. The film’s budget is only $100,000, and the script was written while filming. In this case, it has set a record for the highest box office since the opening of Hong Kong, reaching HK$ 3 million. After Big Brother in Tangshan, Bruce Lee filmed Jingwumen, which doubled the budget compared with Big Brother in Tangshan and caused a greater sensation. Bruce Lee’s fearless spirit and amazing fighting skills in the film, especially his performances of "Li Sanjiao", "Lying Boxing" and "nunchakus", are full of praise. Since then, Bruce Lee has organized the Concord Film Company, edited, directed and acted in the films "The Raptors Crossing the River" and "The Game of Death", and also co-filmed "enter the dragon" with Warner Film Company of the United States, and personally played the leading role. Just as Bruce Lee was ambitious and ready to finish filming The Game of Death, he died suddenly in Hong Kong on July 20th, 1973 at the age of 32 due to drug allergy. 　　The cause of death is a mystery 　　Bruce Lee died more than 30 years ago, and the cause of death is still a mystery. After studying Bruce Lee’s autopsy report, an American expert on the cause of death thought that Bruce Lee died of a rare sudden epileptic death, rather than brain edema caused by drug allergy, because drug allergy only made the patient’s neck swell. 　　Phil Jenkins, an expert at Cook County Death Cause Research Office in Chicago, USA, pointed out that Sudden Epilepsy can cause epileptic symptoms, leading to the failure of the heart or lungs. This disease causes nearly 500 deaths in the UK every year, and the main victims are men aged 20 to 40. Lack of sleep and stress will increase the chances of getting sick. Bruce Lee’s case is in line with the relevant conditions. He was in his prime at the time of the incident and was under great physical and mental stress. 　　Bruce Lee’s autopsy report after death indicated that the cause of death was cerebral edema, and it was suspected that he was allergic to the painkillers he took. However, Phil Jenkins said that drug allergy often leads to swelling of the neck rather than brain, so he didn’t believe that Bruce Lee died of drug allergy.

Bruce Lee (third from left)’ s family photo at the age of 5. Long family 　　Dragon parents 　　Bruce Lee’s father is named Li Haiquan. Li Haiquan is a well-known comedian in Guangdong, one of the four famous and ugly Cantonese operas, and often takes his family to tour all over the world, which is why Bruce Lee was born in the United States. Bruce Lee’s mother, He Jintang, is half German and handsome. 　　As a child, Bruce Lee was very naughty, didn’t like studying, had a strange personality and liked being alone. However, he was very dedicated in making movies, and with his talent, he became a famous child star, which was very popular with girls. Bruce Lee was also a man of temperament since childhood, and making friends with girls was also his hobby. At the age of 13, he entered Ye Wen’s door to learn martial arts, looking for people to fight everywhere, and won the Hong Kong Inter-school Boxing Championship in 1957 and the Hong Kong Cha-cha Open Championship in 58. Bruce Lee and his wife Linda. 　　Mrs. Long　 　　Bruce Lee’s wife, Linda Emily, was his classmate at the University of Washington, and their love experience was quite bumpy. When Linda met Bruce Lee, Bruce Lee was dating Amy, a Japanese girl. Later, Linda joined the "Zhen Fan Guo Shu Guan" founded by Bruce Lee, and learned Kung Fu from Bruce Lee. It can be said that Bruce Lee and Linda had a mentoring relationship at first. Later, Bruce Lee and Amy broke up, and Linda gradually entered Bruce Lee’s life. In 1963, they officially started to associate, and in 1964, they entered the wedding hall. Linda became the lover of Bruce Lee’s life. 　　Linda, Bruce Lee’s wife, gave up her studies for the sake of her family. She always followed Bruce Lee. She didn’t expect Bruce Lee to become an international superstar in the future. She just wished Bruce Lee to achieve her ideal. Bruce Lee’s happiness and success are the greatest happiness in her life. She is a woman who deeply loves Bruce Lee. She has been under a lot of pressure, but her love for Bruce Lee has never changed. Perhaps this is what we call true love for life. After Bruce Lee’s death, Linda remarried and later divorced her husband. Linda also established the Jeet Kune Do Association with Bruce Lee’s disciples in the United States, so as to carry forward and inherit Bruce Lee’s martial arts. Linda, who is nearly seventy years old, now lives in Seattle, USA. Bruce Lee’s son Brandon Lee. 　　Son of the Dragon 　　When Bruce Lee died, Brandon Lee was only 8 years old. Brandon Lee was born a stubborn child, and with a tall and strong body, he has always been king of the children. When he was in middle school, he became famous for being "unreasonable, outrageous and nonsense" and was expelled from three schools successively. When Brandon Lee was 9 years old, his mother, Lianda, began to let him take martial arts classes. Since then, Brandon Lee has embarked on the road of martial arts. Brandon Lee, who is nearly 20 years old, easily stepped into the Hollywood film and television circle with her perfect body shape. As soon as she entered the film industry, she became famous for her exquisite martial arts. 　　In the American film Rapsa Fire (1992), Brandon Lee became first hero, which established his star status in Hollywood. In 1993, Brandon Lee took on an action film with a grotesque style-The Crow. Late at night on March 31st, the filming has come to an end. Brandon Lee will perform a scene in which the hero is shot by a "drug dealer", but after the gunshot, the prop gun in the hand of the "drug dealer" shoots a real bullet and hits Brandon Lee. On the afternoon of April 1st, Brandon Lee died in a nearby hospital, and the death of Brandon Lee became an unsolved mystery. Bruce Lee’s daughter Li Xiangning 　　Little Dragon Maiden 　　In April 1969, Bruce Lee’s daughter Li Xiangning was born. She was five years younger than her brother Brandon Lee. After growing up, Li Xiangning tried to be a martial arts star in addition to co-managing the Bruce Lee Fund with her mother. However, she has always been interested in joining the music industry and hopes to become a singer. Li Xiangning met Brad Laner, a musician of the five-member band Medicine, and reorganized Medicine to make a new album, The Mechanical Forcesof Love. Now Li Xiangning is still active in the art world. She recently participated in the production of the TV series legend of bruce lee, and she is one of the producers of the drama.

　　On September 26, 2012, the first self-developed high-end light truck – "Beyond", which has attracted much attention from the industry, was grandly rolled off the production line at the Nanjing Jiangning factory. Xiao Guopu, vice president of SAIC Motor Group and chairperson of Nanjing Iveco Automobile Co., Ltd., Fabio Mingrino, global vice president of Iveco, Zhou Liang, general manager of Nanjing Iveco Automobile Co., Ltd., and Ni Feng, executive deputy general manager of Nanjing Iveco Automobile Co., Ltd., attended the ceremony and delivered speeches. Famous movie star Jiang Wu was also present as the spokesperson of this high-end light truck.

　　The advent of Transcendence officially sounded the clarion call for Nanjing IVECO to fully enter the high-end light truck field, indicating that Nanjing IVECO’s market strategy has taken a landmark step.

　　High-end, win "quantitative change" with "qualitative change"

　　In recent years, the domestic light truck market structure is accelerating transformation. From the perspective of the proportion of each model, the market share of low-end models is gradually being covered by mid-to-high-end models. Especially after the implementation of the "Twelfth Five-Year Plan", the state actively encourages enterprises to compete and transform, and the commercial automobile industry is also facing a "transition from big to strong". With the continuous improvement of safety standards, emission regulations and fuel economy requirements, the requirement for light truck technology upgrades is becoming more and more urgent, and the high-end industry has become an inevitable trend in the future development of the light truck market.

　　Since 1958, our country’s first self-developed light truck leap into the market, after more than 50 years of development, as an important part of China’s automobile industry, light trucks have become the most concentrated independent brands in China’s automobile industry and the largest export share of the sub-sector. After joining the WTO, light trucks account for an increasing proportion in China’s automobile export strategy, but the export market has always been dominated by Asia, Africa, South America and other regions, making it difficult to enter the European and North American markets with higher emission standards and safety performance requirements.

　　In order to improve the global competitiveness of its own brands, break through existing bottlenecks, and achieve new results in the global market, China’s light trucks must establish new development ideas, while maintaining cost-effective advantages, increase product technology research and development efforts, from low-end to high-end, win quantitative change with qualitative change, and comprehensively improve product quality.

　　"Beyond", a new benchmark for autonomous high-end light trucks

　　As one of the most successful cooperative enterprises between China and Italy, Nanjing IVECO has always taken the global strategy of "based at home and going global" as its development direction. While meeting the needs of the domestic low-end market, it integrates its advantageous resources and increases the integration of high-tech. It uses the world’s most advanced light truck products as a benchmark and competitive model. Relying on the advantageous resources of SAIC Motor Group and the technical heritage of Italy IVECO, under the cooperation of many parties, it tracks the new global automotive technologies and processes, and studies the regulations and market needs of China and other countries in the world. Through the new model of "joint development and independent innovation", it has created a high-end light truck model that surpasses this cutting-edge technology, laying a solid foundation for expanding the international market including Europe, America and other countries.

　　It is reported that this high-end light truck named "Beyond" is Nanjing Iveco, with the full support of the shareholders of SAIC Motor Group and Italy Iveco, through the cooperation of Chinese and foreign technicians, costing hundreds of millions of dollars and four years of painstaking research, before it can be manufactured. The product, whether it is power system, safety performance, intelligent technology or comfort, has international synchronization and domestic leading standards.

　　As a product with the most cutting-edge technology level today, Transcendence has the four characteristics of "high efficiency, safety, consideration and quality". It is a high-end light truck that integrates strong power, avant-garde shape, environmentally friendly emissions, low carbon and energy saving. Transcendence adopts the technology-leading Fiat power chain system, equipped with an F1C engine that can be upgraded to the national V standard, turbocharged intermediate cooling and a 4-valve high-pressure common rail EFI system, ensuring the product characteristics of high power and low fuel consumption, and the comfort and handling of the vehicle are also improved.

　　Beyond the full use of European standard design, with up to 32 patents and 15 key technologies. During the entire development process of the product, the company has conducted a lot of experiments and know the real situation for mainstream light truck products at home and abroad. From dynamic performance to internal and external styling, various performance objectives are finely divided into 482 subjective and objective evaluation indicators, which are used as the general requirements for design, manufacturing and verification. In addition to conducting strict performance tests, the R & D team of Nanjing IVECO has also formulated a complete subjective evaluation system to investigate the subjective feelings of drivers and passengers on the product. The subjective evaluation team composed of multi-national technicians repeatedly evaluated the prototype and put forward improvement opinions, providing a scientific basis for the improvement of various performance levels of the vehicle.

　　The scientific and rigorous development process runs through the entire development process of the product from R & D to production: VE/VA value engineering, SE engineering, quality engineering, vehicle matching engineering; 3 million-kilometer reliability test, RGT and other life tests; SQE review; WCM global manufacturing system…, beyond not only carries the expectations of Nanjing IVECO to fight the high-end light truck market with science and technology as the core competitiveness, but also will serve as a new benchmark product for independent high-end light trucks to fight the high-end light truck market.

　　The Road to "Created in China"

　　The advent of transcendence will break the current pattern of Japanese products thriving in the domestic high-end light truck market, form a situation in which Europe and Japan compete and divide equally, and gradually create a new era of "independent brands synchronizing the world". As Zhou Liang, general manager of Nanjing IVECO, said: The development of a brand requires a long-term accumulation process. From "Made in China" to "Created in China" is by no means achieved overnight. To achieve this transformation, Chinese commercial vehicles must first build a "reliable Made in China brand". Independent research and development and innovation do not mean building cars behind closed doors, but rather combine superior brands, combine their own strength, and integrate core technologies to create a reliable and respected independent brand.

　　To complete the revival of independent brands, not only must we have ordinary products as support, but also need to form breakthroughs and innovations in the high-end field. The advent of Nanjing Iveco’s high-end light truck "Transcendence" has found a broader development path for China’s light trucks. I believe that in the near future, more domestic light truck manufacturers can create their own high-end light trucks through a research and development model such as Nanjing Iveco’s "joint development and independent innovation".
