On May 18th, the State Council Press Office held a routine briefing on the State Council policy, introducing the situation of supporting SMEs to solve difficulties and develop healthily, and answering reporters’ questions. At the meeting, Xu Xiaolan, vice minister of the Ministry of Industry and Information Technology, said that since the beginning of this year, the economic operation of small and medium-sized enterprises has started smoothly. Statistics from the Bureau of Statistics show that the operating income and profits of small and medium-sized industrial enterprises above designated size increased by 14.1% and 6.5% respectively in the first quarter, which fully reflected the resilience and vitality of small and medium-sized enterprises. However, at present, the complexity and uncertainty of the domestic and international environment have obviously increased. We also see that many small and medium-sized enterprises like the service industry and those at the end of the industrial chain have some operational difficulties. Small and medium-sized enterprises generally report that it is difficult to find orders, reduce costs, collect accounts, finance, people and logistics, and make normal production and operation difficult.

Xu Xiaolan said that the new round of epidemic has brought a great impact on the economic operation of small and medium-sized enterprises, but we must see that the long-term fundamentals of China’s economy have not changed. In this regard, the Ministry of Industry and Information Technology, in conjunction with relevant departments and localities, fully implemented the decision-making arrangements of the CPC Central Committee and the State Council, focused on the practical difficulties and needs of SMEs, and implemented detailed policies through horizontal coordination of departments, vertical linkage of ministries and provinces, and demonstration and guidance, and went all out to support SMEs to solve problems and develop healthily.

Original Chinese people’s political consultative conference newspaper

In 1991, China’s first blind road was built and used in Beijing Haidian Landian Factory.

More than 30 years have passed, and on September 1, the barrier-free environment construction law was formally implemented. Is the blind road smooth all the way now? What are the remaining problems? What improvements are needed? Our reporter conducted a field visit and found that the situation is not optimistic.

In the North Road of Landianchang, Haidian District, Beijing, the reporter saw that a blind road set at the corner of the intersection was separated by four manhole covers by more than 3 meters. For a healthy person, it takes only a few steps to walk, but if you are in the dark, every step will be trembling.

Although the cut-off place is paved with a dot reminder brick, it is not easy for the visually impaired to find the starting point of the next section. The reporter blindfolded and tried many times to find the next blind road, all of which ended in failure.

In Sanhuqiao North Road, Haidian District, there is also a truncated blind road, between which there are two telephone poles and a telephone booth. At the entrance of a residential area on the south side of the driveway ditch of Zizhuyuan Road, the iron gate of the residential area directly crosses the middle of the blind road like a roadblock.

During the visit, the reporter also found that with the increase of bike-sharing and electric bicycles, it is not uncommon for blind roads to be occupied.

At the exits of Baishiqiao South Station and Erligou Station of the subway, the dense bike-sharing surrounded the blind road into a "maze". Due to the limited space, more than ten electric vehicles parked directly along the blind road. Not only that, the reporter saw many private cars and engineering vehicles crossing the blind road along the way, which was worrying.

The same situation is not uncommon. At the northeast exit of Yangzhuang subway in Shijingshan District, the blind road directly became the parking lot for electric bicycles, and several rows of electric vehicles were parked. In a section of Haidian District, the reporter saw several blind roads interrupted for various reasons on the sidewalk less than 500 meters short. There is even a situation where a high platform suddenly appears on the blind road. If the blind people pass through this section, they have to go up four or five steps and then down four or five steps before they can find a new blind road. What’s more, the blind road suddenly disappeared on the road, and at the end of the blind road, it was actually a spherical marble isolation pier nearly 1 meter high. When the blind people walked here, they were easily tripped. Moving on, the reporter found that electric vehicles occupied blind roads everywhere. In the west section of this road, because there was a big tree in the middle of the sidewalk, the blind road disappeared after turning right, but just where the blind road disappeared, it was full of bicycles, cars and trolleys of surrounding merchants.

The reporter also observed that the blind roads in some sections have collapsed, damaged and loosened to varying degrees, and the connection between the sidewalk blind roads and bus stations, subway stations and other municipal facilities is insufficient.

Mr. Jia, the supervisor of barrier-free environment construction in Beijing, told the reporter that he had persistently reported all kinds of "chaos" on this blind road to relevant departments through various channels, but "the effect was not great". Mr. Jia said that the formal implementation of the regulations is a good start, and I hope that it can be truly implemented step by step in the future to make our society truly barrier-free.

In addition, our reporter randomly visited on the way of business trip and found that there was a blind road at the departure floor of terminal T2 of Changsha Huanghua Airport, which extended to the vicinity of the check-in area. However, after the security inspection area and the security inspection passage, there is no blind road on the ground of the waiting area of the whole terminal.

On the grounds that relatives of blind people at home need to go out by plane, the reporter consulted the relevant staff, and replied that they could contact the airline in advance to handle the unaccompanied service, which would be sent to the designated place by relatives and friends, signed by the staff and sent to the plane. Upon arrival, there are also special staff to pick up the plane.

It is worth mentioning that on the way to the boarding gate, the reporter found that there are two eye-catching devices providing self-help wheelchairs in the distance of two or three hundred meters.

"Nowadays, the barrier-free environment has been greatly improved, but there are still some details to be improved. I hope that the setting of blind roads can be more humanized." Liang Jiangbo, a visually impaired person, told reporters that barrier-free facilities "are not available, but useful".

During the interview, many CPPCC members also believed that only with "heart and love" can accessibility be truly realized.

With the formal implementation of the barrier-free environment construction law, strengthening the supervision of blind roads has become increasingly prominent. Jiang Xinlu, a member of the Political Consultative Conference of Ningxia Hui Autonomous Region who submitted the Proposal on Strengthening Supervision of Blind Roads this year, called for the cooperation of the Disabled Persons’ Federation, transportation, sanitation, telecommunications, electric power and other departments in the construction, maintenance and supervision of blind roads. He suggested that in daily work, the responsibilities related to the construction, maintenance and supervision of blind roads within the management scope of departments should be implemented, and the supervision and prevention work should be strengthened so that barrier-free facilities such as blind roads can really play their due roles.

"Accessibility is not a form, but a way of life." After more than 10 years of concern and advice on barrier-free environment construction, Zhong Qian, a member of Jinan CPPCC, Shandong Province, felt most deeply that the implementation of legislation is only the first step in barrier-free environment construction. How to implement it exactly and accurately is the key, and more patience and continuous improvement are needed. Everyone is a participant, beneficiary and promoter.

The formal implementation of the barrier-free environment construction law can guarantee the disabled and other people to participate in social life independently, safely and conveniently with a higher standard. During a recent visit, the reporter found that only blind roads, a barrier-free facility, have many problems, such as missing blind roads, being occupied by non-motor vehicles, unscientific design and so on. The road to barrier-free travel for the disabled and the elderly still has a long way to go.

Recently, a photovoltaic dealer broke the news that it was said to be the internal document of Shandong Power Grid Corporation. According to the document, the national subsidy funds for household natural heat distributed projects that were put into operation in parallel from June 1, 2018 to October 31, 2019 will be replenished, which are mainly divided into two categories.

(Source: WeChat WeChat official account "Photovoltaic Policy")

The first category is natural person distributed photovoltaic power generation projects that have been filed and started construction before May 31, 2018 (inclusive) and put into operation in parallel before June 30, 2018 (inclusive). The on-grid electricity price of natural person distributed photovoltaic power generation projects in the "full grid connection" mode is 0.75 yuan/kWh, and the on-grid electricity in the "self-use and surplus grid connection" mode is 0.3949 yuan/kWh, which is subsidized according to the power generation.

The document emphasizes that the national compensation standard and payment method of natural person distributed projects that have paid the national compensation in accordance with the normal settlement cycle remain unchanged, and those that have not paid the national compensation funds, this compensation liquidation is in place.

In the second category, in addition to the above-mentioned subsidy policy before May 31, 2018, other natural person distributed projects with "spontaneous self-use, surplus internet access" mode and "full internet access" mode that were put into operation in parallel from June 1, 2018 (inclusive) to October 31, 2019 (inclusive) were included in the fiscal scale of 2019, and the subsidy standard for full power generation was 0.18 yuan/kwh.

According to the document, the national compensation fund for this kind of natural person distributed project is in place this time.

The document on the second page also states that the recovery period of state-funded funds for the above-mentioned natural and distributed projects is from the date of grid connection to December 2019 (settlement cycle). Since January, 2020, the above-mentioned distributed natural person projects refer to the settlement mode of distributed national supplementary funds for natural persons connected to the grid before May 31, 2018 (inclusive), and the national supplementary funds will be paid normally according to the settlement cycle.

Significant benefits to household photovoltaics

If the documents of the power grid company are issued, it is bound to greatly benefit household photovoltaics, and the household photovoltaic subsidies owed since 531 can be issued in this liquidation. It shows that Shandong Power Grid Corporation strongly supports the development of photovoltaic power generation, especially the care of household photovoltaic power generation, and has taken the initiative to advance the household photovoltaic subsidy that has been in arrears for one and a half years without waiting for the funds of the Ministry of Finance, thus protecting the interests of ordinary people.

Shandong Electric Power Company protects the interests of ordinary people and actively advances household photovoltaic subsidies, which proves the excellent market environment in Shandong Province. Local power supply companies are friendly to photovoltaic power generation, and the grid connection is smooth, and they also actively solve the problem of subsidy arrears. The timely issuance of subsidies has set a good example for other provincial and municipal power companies, and it is believed that the arrears of subsidies nationwide will be properly resolved.

If you haven’t got the household photovoltaic subsidy, don’t worry, the internal documents of the power grid company have been notified, and the money will arrive soon.

　　[car home Professional Evaluation] The scene of getting Tesla Model Y is somewhat similar to that of two years ago. When the imported Model 3 just entered China, we also got the test car first at the beginning of the new year. Time flies, and we can’t catch it. In the past two years, Tesla’s sales and market value have doubled continuously. The gathering of attention also makes the arrival of Model Y more direct than that of Model 3. Therefore, in this article, you can not only see the measured product data, but also see the changes in Tesla products in details.

60 seconds to quickly understand the full text:

　　1. Under the test standard of car home EV AH-100, the high-speed endurance performance (90 2 km/h) of the 2021 Tesla China Model Y long-endurance all-wheel drive model (hereinafter referred to as Model Y) is as follows.356km; Urban low-speed endurance (30 2 km/h)387km;

　　2. The measured acceleration of the car at 0-100km/h is 5.06 seconds; 100-0km/h braking measured 37.89 meters;

　　At present, Tesla Model Y has only launched two models in China, the long-life version and the high-performance version. Our test car this time is2021 Tesla China Model Y long-life all-wheel drive model.. As for the performance of high-performance models, we will also bring you practical tests in the future.

● Endurance test

　　In this test, we used the latest version of car home EV AH-100 test standard, and made some adjustments in some test details and results display. If you want to know the adjustment details of the new test standard, please click here to read the interpretation article of the new standard.

○ Endurance test at low speed.

　　It should be noted in advance that the outdoor ambient temperature of Tesla Model Y is about -5℃ during the endurance test under high and low speed conditions, so this endurance test is a winter test, and the low temperature will have a negative impact on the endurance of pure electric vehicles.Before starting the endurance test at low speed, we fully charge the vehicle, and after the first full battery jump, we conduct three times of charging operation to avoid virtual power.

　　Although the NEDC cruising range of Model Y is 594km, the remaining cruising range after full charge is only 489km. After verifying with Tesla officially, the cruising range of the car isDynamic display based on EPA working conditionTherefore, the battery life of its full meter will vary according to the driver’s comprehensive car habits, vehicle electrical appliances, environmental temperature and other factors; However, turning off the air conditioner or turning on the air conditioner will not affect its battery life.

　　Tesla Model Y does not provide traditional driving modes such as energy saving and sports, and it is an "energy saving state" to adjust the acceleration mode to be relaxed; At the same time, the kinetic energy recovery intensity of the vehicle is only two levels adjustable, and the "standard" means that the kinetic energy recovery intensity is the largest; "Stop Mode" is set to "Hold", that is, the vehicle will not creep at low speed. Of course, before we start the endurance test, we have to turn on the air conditioner to 23℃ for automatic air volume and zero the subtotal mileage.

　　Regarding air conditioning, Tesla Model 3 used PTC air conditioning before, while the new Model 3 and Model Y used heat pump air conditioning. PTC air conditioner has strong heating capacity and high energy consumption. When the ambient temperature is not very low, the heat pump air conditioner has good heating efficiency and low energy consumption, but when the ambient temperature is lower than -10℃ or even colder, the heating effect of the heat pump air conditioner will be relatively general. For the ambient temperature of -5℃ in this test, heat pump air conditioning should be able to play a high efficiency advantage.

　　According to the test standard of EV AH-100, we stopped the endurance test of Model Y at low speed after driving 100.7km. The average vehicle speed was 30.98km/h, and its apparent power consumption was 14.6kWh/100km. After the test, we immediately recharged it, and finally charged it with 20.06kWh, but failed to start it three times. Finally, we get that the energy consumption of the car in this low-speed endurance test is19.9kWh/100kmAccording to the capacity calculation of vehicle power battery, the cruising range of the vehicle under low-speed working conditions is387km. For a medium-sized pure electric SUV, its low-speed energy consumption performance is normal.

　　In that endurance phase of the low-speed work condition,The reduction ratio of actual mileage and apparent cruising range of vehicles is maintained at about 1:1.05.That is, the vehicle travels 20km, and the battery life is reduced by about 21km. Regardless of the endurance of Model Y, its dynamic endurance display based on EPA working conditions can indeed provide more valuable reference for our daily car.

○ Endurance test at high speed.

　　Before starting the high-speed endurance test, we also fully charged the vehicle and recharged it for three times. When the vehicle was fully charged, the cruising range was 488km. At the same time, we will speed up to the easy mode, the kinetic energy recovery will be adjusted to the standard mode, the air conditioner will be turned on to 23℃ for automatic air volume, and the subtotal mileage will be cleared.

　　According to the test standard of EV AH-100, we stopped this high-speed endurance test after driving for 204.2km, and the remaining power of the vehicle was 48%, with a remaining cruising range of 233km.

　　Finally, we charged it with 44.07kWh of electricity. According to the actual mileage and charging amount, the energy consumption of Model Y under this high-speed endurance test is calculated as follows21.6kWh/100kmThe cruising range of the car under this working condition is356km.

　　In the endurance part of high-speed working conditions, the ratio of the actual mileage and the apparent cruising range of the vehicle before 40km is about 1:1.6, that is, the vehicle travels 20km and the apparent cruising range is reduced by about 32km.

　　With the continuous increase of mileage, the proportion of vehicle power failure is slowly decreasing and tends to be stable; After driving for 100km,The reduction ratio of actual mileage and apparent cruising range of vehicles can basically be stabilized at about 1:1.1.High-speed battery life once again verified our point of view given in low-speed battery life:The battery life of Model Y can provide more valuable reference for our daily car..

Charge rate test

　　After the endurance test, we also tested the fast charging speed of Model Y. It takes 52 minutes to charge the car from 30% to 80% on the 120kW DC fast charging pile of State Grid, which is not fast. In the process of fast charging, we recorded the charging power of the vehicle, and the highest charging power was about 47.9kW and the lowest charging power was about 42.9kW.

Summary:

　　According to the actual endurance test results, we calculated the comprehensive endurance performance of Tesla Model Y according to the ratio of 35%+65% intercity high speed+urban low speed.376km；Compared with the NEDC cruising range of Model Y, the actual cruising performance of this car is basically about 60% off. In the low temperature environment, such endurance is not excellent, but it should not be bad. Finally, let’s preview it. In the near future, we will also launch the actual endurance test results of Model Y at room temperature, so stay tuned.

　　Since September 2021, China’s regulatory policy on virtual currency has been upgraded in an all-round way, and various provinces, cities and autonomous regions have successively carried out relevant special rectification actions. On January 26th, the Inner Mongolia Development and Reform Commission issued a notice, deciding to implement the differential electricity price for the virtual currency "mining" project and the "eliminated" enterprise electricity price, with the price increase standard of 1 yuan per kWh (per kWh).

　　On December 3, 2021, Hainan Provincial Development and Reform Commission took the lead in issuing a notice, deciding to classify virtual currency "mining" activities as obsolete industries, and implement differential electricity prices, with the price increase standard of 0.8 yuan per kWh (kWh).

　　A bitcoin investor told The Paper that the policy of differential electricity price is not to allow bitcoin mining, and the policy of cracking down on bitcoin mining is still going on.

　　"The main cost of digging bitcoin is electricity. When bitcoin mining was not cracked down before, the approximate cost of large mines was more than 30 cents for thermal power in winter and cheaper for hydropower in summer. And if the electricity bill increases by 0.8-1 yuan, then digging bitcoin is bound to be a serious loss. " The investor said.

　　Sun Yulin, a senior researcher at Ou Ke Cloud Chain Research Institute, also told The Paper that the implementation of differential electricity prices in Inner Mongolia and Hainan will obviously increase the cost of bitcoin mining. According to the master data on the Okeyun chain, according to the current differential electricity price, the annual electricity fee for each bitcoin mining machine is about 10,000 yuan, and the mining time is about 2 years. After the differential electricity price is implemented, the return time is far away and the electricity cost will increase by about 4 times. Currency price of mainstream mining institutions (data source: f2pool)

　　Take the ant miner S19 as an example, its rated computing power is 95TH/s and its power consumption is 3250w. On January 22nd, based on the electricity fee of 0.1 USD/kWh (i.e. about 0.6 yuan/kWh), f2pool calculated that the pure electricity fee cost (i.e. the shutdown price calculated by f2pool) of this type of mining machine for "mining" a bitcoin was about 17,590 USD. If the electricity fee is increased in 1 yuan, it will be about 2.7 times of the original price, and the pure electricity cost for each bitcoin dug by Ant Mining Machine S19 will also be increased to about 46,907 dollars. At present, the price of Bitcoin is about 35,000-36,000 US dollars, which is far lower than the pure electricity cost of Bitcoin "mining".

　　"Now Bitcoin ‘ Mining ’ If you can make a profit, you can either build a mine overseas, or put a few mining machines at home to steal and make money. " The above investors said.

　　On December 27th, it was learned from the press conference of the State Council Office that in 2025, Spring Festival travel rush will last for 40 days from January 14th to February 22nd. The Ministry of Transport predicts that with the release of policies by all parties, the demand for travel in Spring Festival travel rush will be stronger in 2025, and the total amount of travel and the peak value of a single day may reach a record high. To this end, the Ministry of Transport has taken the lead in setting up a special class for comprehensive transportation in Spring Festival travel rush, striving to achieve the goal of "Safe Spring Festival travel rush, Warm Spring Festival travel rush and Convenient Spring Festival travel rush".

　　At the same time, at the end of the year and the beginning of the year, Li Yang, vice minister of the Ministry of Transport, also published the report card of traffic work in 2024, expressing that he was "very proud, excited and full of confidence" in his achievements.

　　Talking about the source of confidence in the development of the transportation industry, Li Yang pointed out that one of them stems from the endogenous power generated by huge demand. Looking back at Spring Festival travel rush in 2024, the cross-regional mobility reached 8.4 billion person-times. The number of people traveling in the 7 days of the National Day holiday reached 2 billion, especially on the first day of the National Day holiday, the travel data reached a new high: the total number of people traveling reached a peak of 330 million on October 1; Railway passenger traffic reached 21.44 million passengers, a single-day high; The traffic volume of expressways reached 68.41 million, of which new energy vehicles accounted for 15.9%. The strong travel demand injected strong impetus into traffic development.

　　The second is a stronger foundation for development. China’s comprehensive three-dimensional transportation network has reached a new level, with a mileage of 6 million kilometers. Major projects such as the Shenzhen-China Passage are completed and put into operation. Civil aviation is expected to add five certified civil transport airports, with a railway mileage exceeding 160,000 kilometers, including 46,000 kilometers for high-speed railways, about 50,000 kilometers for new highways and 8,000 kilometers for newly rebuilt and expanded expressways. There has also been a major breakthrough in international transportation channels, such as trans-Caspian transportation corridor, direct highway transportation and the opening of Qiankai Port in Peru, opening up new routes for China-Europe and China-Latin America trade.

　　The third is full of development potential. A series of economic incremental policies have continuously released the traffic dividend, and the policies of "duality" and "two innovations" have continued to be effective. In November, the growth rate of freight volume and port cargo throughput increased, accelerating by 4.2% and 3.7% respectively year-on-year, which has saved enough stamina for subsequent development and continuously promoted the steady progress of the transportation industry.

　　Looking forward to 2025, Li Yang believes that there are challenges and opportunities, and the opportunities outweigh the challenges. On the one hand, hold the policy "baton" and promote the construction of major projects. The list of major projects in 2025 has been drawn up, and the Pinglu Canal under construction, Shanghai Port Xiaoyangshan North Container Terminal, Shanghai-Chongqing-Rongjiang high-speed railway and other projects are speeding up the weaving of the national comprehensive three-dimensional transportation network.

　　Furthermore, give full play to the advantages of comprehensive transportation to help reduce costs and increase efficiency. It is estimated that in 2025, it is expected to reduce the logistics cost of the whole society by 300 billion yuan, providing solid support for the real economy, especially the manufacturing industry. It will also deepen the reform of the comprehensive transportation system, promote the reform of the railway system, accelerate the development of general aviation and low-altitude economy, and release the vitality of development through reform.

　　In addition, pay close attention to safety production and let people travel with peace of mind. In 2025, Spring Festival travel rush will carry out two nationwide investigations and rectification of potential safety hazards before and after May Day. For the Spring Festival, May Day and National Day holidays, "30 hard measures" were adopted to improve holiday safety with stricter standards. (Wu Na)

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.

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.

　　When spring comes, you should be careful of excessive liver fire and cardiovascular and cerebrovascular health. Mothers who need to accompany them to do their homework should take care of themselves. "Roar" is too strong and their blood pressure rises. If they run into deformed blood vessels, they may really burst them!

　　On the afternoon of March 29th, Professor Liang Donghui, Director of zhujiang hospital Department of Traditional Chinese Medicine of Southern Medical University, visited Guangzhou Daily to make an appointment with famous doctors for micro-class, giving advice on cardiovascular and cerebrovascular maintenance and disease prevention in spring. He reminded that it is still the peak period of cardiovascular and cerebrovascular diseases, and many times cardiovascular and cerebrovascular diseases are accompanied by mental and emotional problems such as anxiety and depression. It is very important to "treat both body and mind".

　　Text/Guangzhou Daily All-Media Reporter Zhou Jieying Correspondent Wu Xiaodan

　　Spring is coming, "heart disease" still needs to be prevented.

　　Many old patients with cardiovascular and cerebrovascular diseases will feel that the most dangerous winter has passed and they can breathe a sigh of relief. Liang Donghui reminded that research shows that cardiovascular and cerebrovascular diseases have two peak periods every year, one in autumn and winter and the other in spring.

　　External cause: the climate is hot and cold.

　　Especially in spring in Lingnan area, the climate is changeable, and it is hot and cold, which is easy to cause acute attacks of cardiovascular and cerebrovascular diseases. In particular, patients with hypertension and coronary heart disease are prone to angina pectoris, even myocardial infarction and stroke. Therefore, the folk proverb of "covering spring and freezing autumn" is very reasonable. "Spring cover" means that the temperature in spring has just warmed up, so it is not appropriate to take off winter clothes too early, because it is warm and cold at this time, and the temperature difference between morning and evening is relatively large. It is difficult to adapt to taking off winter clothes too early, once the temperature drops, the human body’s resistance will decrease and blood pressure will fluctuate greatly, which will easily lead to the increase of myocardial oxygen consumption index and increase the heart load.

　　When blood vessels are stimulated by cold, they will spasm. People with atherosclerotic plaques, those unstable plaques will rupture and fall off, resulting in myocardial infarction and cerebral infarction.

　　Internal cause: hyperactivity of liver and emotional uncertainty.

　　In addition to external factors, spring "heart disease" is prone to internal factors. Traditional Chinese medicine believes that spring belongs to wood in the five elements, and the liver belongs to wood in the five internal organs of the human body (heart, liver, spleen, lung and kidney). Spring qi passes through the liver, and liver qi rises vigorously. Many people with high blood pressure have a common physical feature — — Hyperactivity of liver yang and vigorous liver fire. In spring, their mood is often very unstable, and they are prone to lose their temper. When they lose their temper, their blood pressure will increase, and cardiovascular and cerebrovascular diseases will easily occur.

　　Do three things to protect cardiovascular and cerebrovascular diseases in spring.

　　Liang Donghui said that a healthy body needs active and continuous maintenance. For middle-aged and elderly people, especially those with cardiovascular and cerebrovascular diseases and high-risk groups, it is very important to do seasonal prevention work, which can reduce the incidence and reduce the serious harm caused by diseases. Care for blood vessels in spring should pay attention to the following three aspects:

　　1. Don’t let your body catch cold, keep warm and reduce the heart load.

　　Pay attention to the change of weather, add and reduce clothes in time, and would rather wear more clothes than freeze. Especially when going out in the morning and evening, pay attention to keep warm and wear a good hat to prevent cold wind from invading the body, causing blood pressure fluctuation and vasospasm, avoiding the rupture of unstable plaques and causing myocardial infarction, and also reducing the heart load.

　　2. Eat a reasonable diet and eat more bud vegetables in spring, which will help the yang to rise.

　　For patients with cardiovascular diseases, it is necessary to keep your mouth shut at all times, and eating and drinking may cause illness at any time. To prevent cardiovascular and cerebrovascular diseases, the diet is mainly coarse grains and vegetables, and it should be low in oil, salt, fat and sugar.

　　In the season when the yang rises in spring, the human body’s yang conforms to nature, and it is scattered upward and outward. You can eat foods that warm and tonify the yang and disperse the temperature rise, such as onions, garlic, ginger and leeks. Sprouting vegetables such as bean sprouts, Toona sinensis, tender bamboo shoots and spinach also contribute to the rise of yang. You can eat more onions, tomatoes, loofah, eggplant, fungus, etc. These foods can resist arteriosclerosis and reduce blood fat. Edible foods that are sweet and spleen-nourishing, such as jujube and yam. Eat more fresh fruits and vegetables to help calm and nourish the liver.

　　3. Keep a good mood, and avoid mood swings of great joy and great sorrow.

　　Spring is the time when the liver is flourishing. Chinese medicine believes that the liver governs the release of qi, which means that maintaining psychological balance and emotional stability is beneficial to the health of the heart and blood vessels and can reduce the incidence of cardiovascular and cerebrovascular diseases.

　　Never avoid the emotional fluctuation of great joy and great sorrow, which will easily lead to blood pressure fluctuation, autonomic nerve dysfunction and cardiovascular and cerebrovascular diseases. Especially those patients with cardiovascular and cerebrovascular diseases with depression and anxiety at the same time should be more vigilant.

　　If you want "heart" health, you must also pay attention to "mood" health

　　Often "heart jam" for some daily trifles may lead to real "heart jam" for a long time. Liang Donghui said that in clinical practice, it is found that more and more patients with cardiovascular and cerebrovascular diseases have mental and psychological problems. The comorbidity rate of cardiovascular and cerebrovascular diseases with depression and anxiety disorder is very high.

　　Some research data show that the proportion of cardiovascular patients with depression and anxiety is 22.8% and 70.9% respectively, and the incidence rate of women is higher than that of men; The incidence of post-stroke depression was 36%, and mild depression accounted for 80%. Psycho-psychological factors are the risk factors to promote the occurrence and development of cardiovascular and cerebrovascular diseases, and these two kinds of diseases interact with each other and jointly lead to the deterioration of the diseases.

　　Some patients with organic heart disease have experienced first aid, surgery and other blows, as well as a variety of maladjustments after illness, which will lead to psychological problems such as anxiety and depression. Some patients are uncomfortable, but after all kinds of examinations, all kinds of indicators are normal. This is often not a "job", but it is probably a physical manifestation of mental and psychological disorders such as depression and anxiety. If we don’t intervene, it will probably develop into a real body organic disease, that is, it will really evolve into cardiovascular and cerebrovascular diseases such as coronary heart disease.

　　Experts remind that if someone in the family always feels uncomfortable and can’t find the reason for going to the hospital, they must be patient, understand more, explain more, and seek help from mental and psychological professionals when appropriate.

　　Daily chest distress and palpitation can be relieved by pressing two acupoints.

　　Liang Donghui said that if the patient is diagnosed with "double heart disease" with cardiovascular disease and psychological disorder at the same time, the doctor should conduct corresponding dual diagnosis and treatment and "treat both mind and body". However, the family and society should also have corresponding support, and patients should "relax" and face the disease positively. Sometimes they might as well do health exercises, Tai Ji Chuan and Ba Duan Jin under the guidance of Chinese medicine practitioners.

　　If there are some symptoms such as chest tightness and palpitation at ordinary times, what method can be temporarily relieved? Liang Donghui introduced two methods of acupressure. In case of cardiovascular and cerebrovascular diseases, you can massage yourself while waiting for the arrival of professional ambulance personnel, which has good anti-angina and anti-arrhythmia effects. Daily massage can also play the role of health care and heart protection, and patients with atrial fibrillation, premature beats, arrhythmia and other diseases can use it to regulate themselves.

　　1. Neiguan point: Regular pressing has the functions of calming the heart, calming the nerves, regulating qi and relieving pain, and is called Baoxin Yaoxue. Sometimes gastrointestinal discomfort, such as nausea and vomiting, and even motion sickness, can be relieved by pressing this point.

　　【 Acupoint selection method 】 The transverse palmar stripes are pointed upwards by three fingers, and the midpoint of the two tendons is Neiguan point, between the palmar longus tendon and the flexor carpi radialis tendon.

　　[Massage method] Press the thumb on Neiguan point, press the index finger on the corresponding Waiguan point on the outer side of the arm, and force the finger vertically downward, and it is appropriate to feel sore. After pressing for 20~30 seconds each time, gradually release it, and then press it down again. Press each hand for 3~5 minutes, and then change the inner and outer points at the corresponding position on the other side for the same time and method.

　　2. Taichong point: Regular pressing has the effect of calming the liver and suppressing yang, which can relieve hypertension, dizziness and headache.

　　【 Acupoint selection method 】 It is located at the back of the foot, at the front depression of the joint of the first metatarsal and the second metatarsal.

　　[Massage Method] Press your fingers down on the acupoints, then massage them, with moderate intensity, so as to produce a feeling of soreness. Press each acupoint repeatedly for 1-2 minutes, and then change one side to the corresponding position of the other foot, and massage in the same way.

　　February 4th is the 17th World Cancer Day, and this year’s theme is "WE CAN, I CAN". The member of the Standing Committee of Cancer Radiotherapy Committee of China Anti-Cancer Association and the president of Cancer Hospital said: At present, 70% of cancer patients in our city are in the middle and late stage when they are diagnosed, so it may be a better choice for them to eliminate the fear of cancer and realize coexistence with cancer.

　　70% of cancer patients need to live with tumors.

　　Mr. Luo, who lives in Yubei District, is 55 years old. He is used to working from nine to five every day. If no one tells him, no one will think that he is actually a cancer patient. Five years ago, he suddenly felt that he was always urinating, but he couldn’t urinate. At first, he thought he was getting angry. But a pile of heat-clearing drugs didn’t improve after eating, and the more urgent the urine, the less smooth it was, and sometimes it was accompanied by pain. At this time, he thought about going to the hospital for examination.

　　I didn’t want to be diagnosed with prostate cancer and have bone metastasis. I have lost the best opportunity for surgery and can only use antiandrogen drugs to control my condition. In the face of cancer, he did not intend to give up, but actively cooperated with the treatment. After one year, his condition gradually stabilized, and Mr. Luo began to plan to go to work in the unit.

　　Professor Dean of the Municipal Cancer Hospital said that according to the "2015 China Cancer Statistics" issued by the National Cancer Center, there were 4.3 million new cancer cases in China in 2015, and the number of cancer deaths exceeded 2.8 million; In Chongqing, there were about 80,000 new tumors and more than 50,000 cancer deaths in 2014. Because the incidence of tumor is relatively concealed, more than 70% of cancers are found in the middle and late stages, and the best opportunity for surgical treatment is lost. For them, survival with tumor may be a better choice.

　　Unfortunately, in real life, there are not many patients who can scientifically understand the survival with tumors like Mr. Luo. As soon as many patients heard that they could not operate, their spirits suddenly collapsed and they thought they were hopeless. In fact, surgical treatment is not the only treatment for all tumors; Even if we miss the best opportunity for surgical treatment, it doesn’t mean that there is no cure. At present, tumor treatment advocates comprehensive treatment, which includes surgery, chemotherapy, radiotherapy, endocrine therapy, traditional Chinese medicine treatment and other ways. Experienced specialists will choose the appropriate treatment according to the results of tumor pathological examination, course of disease and development trend.

　　"It is very important for cancer patients and their families to accept" survival with tumor ",which is a more pragmatic method for treating advanced cancer." Dean said that cancer is essentially a genetic disease, and all cancers come from genetic mutation, which is caused by genetic mutation and epigenetic regulation. At present, human beings can’t use drugs to reverse this genetic mutation and "kill all cancer cells" in the body.

　　It is also a pragmatic choice for patients in the middle and late stage to realize long-term "survival with tumor" and "peaceful coexistence" with tumor. Everyone should treat it as a medical disease with disease, and treat tumor as a chronic disease such as hypertension, diabetes and coronary heart disease, which is more conducive to treatment.

　　The misunderstanding of survival with tumor needs to be vigilant

　　There may be many people who don’t understand that living with a tumor is not cured. There is a tumor in the body, and the condition may deteriorate at any time. Can this be safe? Dean Wu Yongzhong said that in fact, survival with tumor is not to let it go, but to choose a suitable treatment model, which is also the core of "individual medicine" developed from "evidence-based medicine" in recent years. First of all, we should recognize the fact that the dream of conquering tumor has not been realized.

　　WHO has regarded tumor as a chronic disease, because its condition has a process of development, which can not be cured and exists for life, just like diabetes, hypertension and coronary heart disease. Secondly, sometimes over-active treatment is also a kind of injury. In clinic, some elderly cancer patients are often encountered. When children hear that they can have surgery and treat at all costs, they have not achieved good results. This is because the elderly, especially those over 80 years old, have degraded their physical functions and cannot tolerate surgery and chemotherapy at all.

　　At this time, you don’t have to think about eliminating the tumor at all. You can choose radiotherapy alone or other treatments, so as to survive with cancer. Advocating survival with tumor again also means waiting for treatment conservatively. If it can be cured by surgical resection, radiotherapy and other treatment methods, tumor patients should still be encouraged to actively treat.

　　Age-related macular degeneration (AMD) mostly occurs in people over the age of 50, and it is one of the main blinding diseases of the elderly in the world. According to statistics in 2010, there are more than 23 million AMD patients worldwide. The patient’s chief complaint is decreased vision, which is characterized by the absence of central visual field (see schematic diagram).

　　Normal visual field (left), central visual field damage caused by AMD (right)

　　Age-related macular degeneration can be divided into Dry AMD and Wet AMD. Dry amd is characterized by no vascular proliferation, while wet amd is characterized by obvious vascular proliferation in macular area. There is almost no treatment for dry age-related macular degeneration, while wet age-related macular degeneration is mainly aimed at vascular proliferation. For vascular proliferation, Genentech’s Ranibizumab (trade name: Lucentis) is a fragment antibody against VEGFA, and it costs two thousand dollars for a shot. However, many places bypass Ranibizumab and choose Avastin (Avastin), which is also anti-VEGF, for only fifty dollars. It can be seen that there are policies and countermeasures, which are available to people at all times and all over the world, but the interests are accelerating. In addition, laser therapy is also aimed at vascular proliferation. Although there is symptomatic treatment for vascular hyperplasia, it is also a temporary solution, because macular degeneration itself has not improved.

　　A core problem of macular degeneration is degeneration of retinal pigment epithelial cells (RPE). These cells are close to the interlayer between Choroid and optic nerve cells in retina, and are responsible for bringing blood nutrition to optic nerve cells. If this layer of cells degenerates, the optic nerve cells will not get nutrition, so the vision will decrease. There’s an old saying in China, what can I do without fur? Is the image explanation of this disease.

　　A remarkable pathological feature of macular degeneration is yellow sediment distributed on the retina, which is a mixture of protein and lipid, but its source is unknown, and it may be an inflammatory product, and its pathological function is to destroy retinal pigment epithelial cells (RPE). See the figure below.

　　Since it is a degenerative disease, the research and development of drugs lacks molecular targets, which are a bit like Alzheimer’s disease and neurodegeneration, and there are not many effective targets. In contrast, the stem cell technology that surfaced in the past ten years is an ideal choice. Stem cells are induced to differentiate into retinal pigment epithelial cells (RPE), which provides a feasible and effective method for the treatment of macular degeneration.

　　Can normal retina replace diseased retina? A few decades ago, someone replaced the diseased retina with the baby’s retina (of course, the source was the baby who died in a car accident under two years old), and the success rate was very low, because the source of newborn retina was difficult, the protection was difficult, and the operation was difficult, which were all restrictive factors. However, some people have gained some vision (such as light perception and figure) through retinal replacement. This scheme can at least prove that infant retinal replacement is a direction that can be improved. However, it is not successful to replace the bad eye retina with the good eye retina of the same adult, which shows that the physiological age of retina is an important reason. Nowadays, retinal pigment epithelial cells (RPE) can be produced from stem cells, whether from embryonic sources (hESC) or from self-induced sources (iPSC), and they can be made into Sheet, which is beneficial to surgical implantation. Of course, there are many technical problems, mainly the problem of eye surgery and the problem of ensuring the survival of cells after implantation. A positive factor is that the eye is an immune escape, so don’t use immunosuppressants, immune rejection should be small, which is conducive to survival.

　　Regenerative medicine is a new field, and big pharmaceutical companies are unwilling to take this risk. Seven years ago, the author worked in the world’s largest ophthalmic pharmaceutical company (Allergan) and once recommended this project, but the decision makers are interested in Miu Miu. At present, several small companies have pushed the application of regenerative medicine in senile macular degeneration into the clinical stage. Although I dare not predict when it will be approved by the FDA, it is still expected as a promising direction. After all, there is no other way at present. Although the experiment of regenerative medicine is still in the "primary stage of socialism", the AMD market is very large, and there are still some large and medium-sized pharmaceutical companies to follow up. Not long ago, Astra, the second largest pharmaceutical company in Japan, bought Ocata Therapeutics LLC to jointly develop this method for treating AMD, which mainly focuses on hESC inducing retinal pigment epithelial cells (RPE).

　　Regenerative medicine is not only dedicated to age-related degenerative macular degeneration (AMD), but also can be used to treat another cause of blindness, Retinal pigmentosa. It also damages retinal pigment epithelial cells (RPE), but retinal pigment degeneration damages peripheral visual field, and other eye diseases such as glaucoma and corneal burn. In order to give you a big picture of regenerative medicine in treating ophthalmic diseases, the author summarizes the general situation of some companies entering clinical trials at present. I sincerely hope that these companies can succeed in regenerative medicine and bring good news to patients with ophthalmic diseases.
