　　As the leader of the medical treatment team in Shanghai centralized isolation point, Chen Erzhen, vice president of Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, is the "fire fighting captain" in the construction of Shanghai’s "shelter". At present, his new stop is the National Convention and Exhibition Center (Shanghai), which will soon become a super shelter isolation point with 50,000 beds.

　　On April 8, Shanghai reported that there were more than 20,000 new positive people the day before. Can the intensive construction of shelter meet the needs of admission? How can such a huge shelter hospital ensure the treatment and life of infected people after they check in? Dajiangdong Studio once again interviewed Chen Erzhen.

　　Chen Erzhen was interviewed by Dajiangdong. Gu Haimin

　　Dajiangdong: With such a large-scale shelter hospital, how will we ensure the treatment and daily life of infected people after admission?

　　Chen erzhen:This is the largest shelter hospital with the largest capacity in history. There are 14 cabins in total. In the future, there will be more than 50,000 people who are infected with COVID-19, 5,000 to 6,000 medical personnel and nearly 10,000 security personnel, which adds up to 60,000 to 70,000 people. This is similar to opening a large exhibition in peacetime.

　　To ensure safety and prevent secondary disasters, we must be more detailed and practical, and we must think more about many details, plans for problems and possible unexpected situations, and we must have many countermeasures.

　　At the same time, efforts should be made to improve the living environment of infected people. With the construction of shelter hospitals, our experience is getting richer and richer, and we try our best to make the hardware conditions better. For example, sanitary facilities, many citizens will not adapt at once, which is too different from the environment at home, but we are trying our best to improve them. For example, the problem of taking a bath and going to the toilet must be much better this time.Taking a bath can meet the basic shower requirements.For example, 10 minutes for lesbians and 5 minutes for gay men will improve the turnover rate, but it is better than nothing. In terms of barrier-free access, it has also been greatly improved.If the earliest shelter hospital in Shanghai was version 1.0, it was later developed into version 2.0, and this time it is version 3.0.

　　The management process has also been continuously improved and optimized. After the shelter is completed, logistics support is very important. How many materials do so many people need to eat and drink Lazar? To ensure that so many people get effective medical observation, once there is sudden medical treatment, how much medical equipment should there be? How to arrange our personnel reasonably?We can neither waste precious medical staff nor increase the risks they are exposed to. We must ensure that they are in place and standardize their protection.

　　Dajiangdong: How many other provinces and cities support the medical team here now? How to manage it properly?

　　Chen erzhen:Our demand is about 5000 people. The most important thing is to build this place quickly, so people can’t come and wait outside, and the connection must be done well. Human resource management is very challenging, and information security is also very critical. It also includes nucleic acid testing. Sixty or seventy thousand people test nucleic acids once a day, and the amount is also very large.

　　We often say that sparrows are small and complete, so there are many details to be considered for such a behemoth (Fangcang Hospital). If it is not properly managed, the effect will be very, very poor. The city attaches great importance to it, with special classes and coordination in all aspects.Through these efforts, I believe that in the process of construction, we will continue to explore experience and refine management methods to ensure that this shelter can be opened and used safely and orderly, and play a role in the great battle against epidemic in Shanghai.

　　Dajiangdong: There are more cabins in Shanghai at present. What kind of system is this? Is it enough?

　　Chen erzhen:At present, Shanghai is a city-level and district-level shelter hospital system construction, such as the National Convention and Exhibition Center (Shanghai), the New International Expo Center, the Expo Exhibition Hall, the Renaissance Pavilion of the Expo, and the Yangshan Special Protection Zone in Lingang are relatively large — — Together, these five large cabins can accommodate more than 80,000 people for medical observation, which is managed at the municipal level. At the same time, each district should build corresponding cabins. From the current resources, Shanghai can have more than 40 cabins of different sizes, with a total bed of more than 100,000.

　　Next, the shelter will be in a state of "in and out", and many people have begun to leave the hospital.Everyone is more concerned about whether the shelter construction can meet the needs of new positive people in Shanghai. I think the most important thing is whether our early prevention and control measures and restrictions on people’s activities are in place. If there are still infected people moving around the society and spreading the virus everywhere, there will be a large number of new ones every day; If everyone cooperates with epidemic prevention and stays indoors, I believe that the turning point will come earlier after the spread speed slows down.

　　For infectious diseases, controlling the source of infection, cutting off the route of transmission and protecting vulnerable people are international common means.Among these three "pillars", controlling the source of infection means "should be separated"; Cutting off the route of transmission is to control the flow of people.

　　Surface spread may also be a way, depending on its temperature, humidity and material, and the basic research in this area should be strengthened. Is there any other way? Is there any "darkness" in the virus?It is very important for us to continue to strengthen our research to see if there are any routes of transmission that we have not found and neglected.

　　Dajiangdong: Now the proportion of asymptomatic infected people is very, very high, which is different from the previous situation? Is there any change in diagnosis and treatment standards?

　　Chen erzhen:A large-scale epidemic in Shanghai has been going on for 20 days. In this process, our understanding of the virus is also deepening. According to the characteristics of patients and the summary of experience, it is necessary to standardize the diagnosis and treatment, and there should be corresponding changes in the management and isolation, including the hospital infection protection system. It should be analyzed according to scientific data and provide good countermeasures, which will help to scientifically and accurately deal with the current epidemic prevention and control situation and improve our epidemic prevention system in the future.Make a more scientific, operable and effective diagnosis and treatment plan to make it quick.

　　Dajiangdong: With the emergence of a large number of patients, the work intensity of medical staff is also great. How should we prevent hospital feeling?

　　Chen erzhenFrom the management point of view, hospital feeling is not allowed to happen. There is no doubt that if you can’t protect your own employees and let them work safely, what’s the fight?

　　We protect the safety of medical care in order to treat and protect more patients. But as a "war", it may be inevitable that there will be "casualties" and "material damage". If there is a sense of hospital in the subsequent case, we must first analyze the reasons and why it happened. It should be analyzed from hardware, software, personnel and other aspects, such as whether the infrastructure construction is right or not, and whether there will be "air leakage" everywhere; Whether the process is correct and the setting is reasonable; How is people’s compliance, and whether wearing masks and protective clothing is standardized … … Specific problems should be treated accurately and solved quickly, and there should be scientific and objective analysis.

　　No mistakes are allowed, there is no doubt about it. We must be strict with requirements and standards. But to err is human, how to analyze the reasons for making mistakes, is it preventable or not? How to learn from failure?

　　Recently, although I was very busy, I watched The Battle at Lake Changjin — — In such a difficult environment, we all defeated the enemy, so now we are facing a "war without smoke", and we still have to win the greatest victory with the least cost.

　　Dajiangdong: We will welcome many citizens who leave the cabin and turn to the shade one after another. What do you think of this process for themselves and society?

　　Chen erzhen:Epidemic situation, from a professional point of view, is also a kind of disaster. Everyone will have a stress reaction when they encounter such a disaster. Even if it is not isolated in the shelter, even if it is sealed in the community, it will feel depressed, which is a common psychological reaction after the disaster.

　　Different people will have different psychological reactions. Some people will be anxious all the time, some people may forget everything after sleeping, some people will remember this paragraph forever as time goes by, and some people will have nothing. We must have a psychological team and the help of volunteers. This is a social systematic project. Establishing a psychological assistance team to help everyone solve the psychological burden after the epidemic is what we call an important process of "post-disaster reconstruction".

　　　　Then the discharged patients will return to the community and go home for health management as required. I believe that with the construction and operation of our shelter hospital, we will soon usher in a discharge peak. (Li Hongbing Ju Yunpeng)

CCTV News:Wearing navy flame-retardant work clothes, quietly sitting on the edge of the console, wearing a mask and welding cap, a right-hand welding torch and a left-hand welding wire, Liu Hongguang slowly moved the tools in his hand to the joint of the test piece on the console, stared at it for a few seconds and closed his eyes.

Press the control switch of the welding torch, the silvery white arc lights up, the welding torch of the right hand slowly translates, and the left hand rhythmically adds a little bit of wire. After about 20 seconds, the arc is put away and the welding is over. Liu Hongguang opened his eyes, looked at the symmetrical "fish scale pattern" shining with metallic luster at the joint of the test piece, and nodded slightly … …

Liu Hongguang, the deputy head of the welding team and the first "Chief Technician" appraised and hired by China Aerospace Science and Industry Corporation, showed his stunt — — "Blind welding".

Liu Hongguang, Welder of Rocket Engine Shell

Become famous at a young age: from an apprentice to a chief technician

When I first joined the work, there were many people and few jobs. Generally speaking, I may not get a chance to weld alone after three or four years as an apprentice. In order to master the welding technology better, Master stood by and watched all the time while welding, never letting go of every detail. After the work, use scattered time to find some scraps to practice. During his apprenticeship, he welded countless test pieces. At that time, colleagues often joked with him: "Xiao Liu is thin as corn stalks, and his little face is baked into potato skins!" Hard work is hard work, and day after day’s practice has enabled him to master solid basic skills.

In 1998, the factory held the first mentoring activity at that time, and was lucky enough to become a mentor with Master Chen Yong. With the guidance and help of Master Chen Yong, Liu Hongguang won the first place in theoretical examination and practical operation, becoming the first skilled worker in the history of the factory to be directly promoted from a junior worker to a senior worker.

Welders are sometimes regarded as "hard work without wisdom, hard work without showing their faces". This also reflects the monotony of this type of work and the lack of hard work for others. Sometimes in some workplaces with narrow space, when welding a workpiece, one posture should be kept for a whole day, and when it is over, one usually can’t stand up straight. In summer, the flame emitted by the welding torch is more than 200 degrees Celsius, which is basically an arc roast on the face and a "sauna" on the body; In winter, sometimes you need to lie on cold products, and your joints are often numb and blue. Welders also have another feature, which affects the whole body, sometimes breathing or shaking their arms will affect the overall quality of the weld. Once, when welding products, a large piece of fiery red welding slag fell on the protective clothing. At first, I didn’t notice it. When I felt my legs burning, the thick clothes had burned a hole the size of a bowl. Even so, I could only gently bounce off the welding slag on my clothes and continue to finish the work at hand.

"Because of the particularity of welding work, the welding torch in his hand is the life of aerospace products, and he must keep 100% concentration at all times, feel every weld with his heart, and condense every solder joint with his heart", which is the principle he has practiced for many years. In 2000, Liu Hongguang participated in the fourth welder technical competition in Inner Mongolia and won the Excellence Award. He was named "Excellent Young Post Expert in the Region". In 2002, he won the third place in the first China Aerospace Science and Technology Industry Vocational Skills Competition, and in the same year, he was awarded the honorary title of "National Technical Expert"; In 2004, he was awarded the position of youth expert by Aerospace Science and Industry Corporation; In 2005, he was awarded the title of "Young Master in Central Enterprises" and "Chief Technician" in 2009.

Ensure the weld is perfect from the inside out.

After painstaking study, a weld is a lifeline.

As the heart of aerospace products, engine welding is an important part. "Every weld is a lifeline, and one weld will be qualified." In his work, Liu Hongguang never let go of every detail and every seam. He kept exploring, studying and improving, and summed up the working method of "looking, smelling, asking and cutting" in his years of work.

"Looking" means "observing", which is the first key in work. Up to now, Liu Hongguang still remembers the embarrassment when he first entered the factory. When he first came, he couldn’t handle anything, even the welding torch was unstable, and there was no product to be used for welding. The best way to learn was to watch the master’s work. Whenever the master did a job, he stared at every detail, observing the master’s "when to get off the gun, where to start, and how long to weld", all of which were memorized by heart, as if he were more devoted and more than the master.

"Although there is a molding process in welding, sometimes the technique is very important, and skilled welding feeling is an indispensable condition to ensure the quality of products", which is Liu Hongguang’s second secret "cutting", which means "practice". Due to the high quality of aerospace products and the particularity of materials, in the first few years as an apprentice, we can only use the scrap of different types of old steel plates and covered electrode for welding practice. In practice, we can weld test pieces from multiple angles and directions, and constantly explore and accumulate experience. In order to complete the welding task of a difficult product, he improved the welding gun nozzle, used several abandoned non-standard nozzles, and after several days of polishing, he ground out the nozzle suitable for welding this type of product.

According to the traditional practice, for welding a certain type of product, the technicians should first work out the process, such as how much current and voltage to use, what kind of welding wire to choose, how fast to add wire, and what welding method to use, and this process is relatively fixed. But in fact, the process often gives a range of parameters, and which value is the best condition depends on practice. Old masters used to rely on feelings and experience, but Liu Hongguang combined these feelings and experiences with every production practice, and defined more specific parameters for many processes. According to these parameters and processes provided by him, he helped colleagues to weld finished products directly.

Liu Hongguang’s third secret is "smell". Learning from books is his persistent habit all the year round. In my own home, the small study is full of all kinds of books, most of which are welding. In the past few years, he used his spare time to teach himself a large number of books on welding, machining, science and technology, technology, etc., and made 20 Yu Ben in his work notes alone, and successfully completed the courses of RTVU and obtained the undergraduate diploma. As the saying goes, "there must be a teacher in a threesome." At work, always learn from others and practice, and learn creatively, break the usual thinking habits and work patterns, learn from others’ unique skills and turn them into their own skills.

"Asking" means "thinking", which is the fourth secret of Liu Hongguang. When the solid power cause is not completed, it will always be in progress, and new problems will be constantly encountered in the work. It is his working habit to keep asking questions to difficult problems and bottlenecks for many years. It is precisely because of this work habit that he explored and developed a variety of welding methods according to the characteristics of different models of products.

There is a notebook in his workshop locker with work summary, process optimization record, product defect solution, etc. The latest record is about the analysis of weld cracks detected by a certain igniter in the later stage. This is an old problem that has existed for more than 10 years. Liu Hongguang took the unqualified products back and dissected them to find out the reasons. After improving the method, the late pass rate of this type of products increased from about 30% to over 90%. 　 　 　 　

Here, I have to mention Liu Hongguang’s unique skill "blind welding". His best manual welding needs two hands to cooperate. The distance between the welding wire and the tungsten electrode at the top of the welding torch is calculated in millimeters, and the distance between the tungsten electrode and the weldment is also kept at about 1 millimeter. If it is far away, it will affect the welding effect and even lead to welding failure. "Blind welding" means that the grasp of this 1 mm distance depends not on the eyes, but only on the feeling on the hands and the change of welding sound.

No matter how irregular weldments and materials are difficult to control, Liu Hongguang can finally "give" them a weld with a symmetrical and beautiful appearance and a uniform and dense structure inside. This kind of weld looks like pieces of fish scales stacked at random, and the width of each piece is basically the same, so it is called "fish scale pattern".

In August 2014, the "Jiake" Cup International Welding Skills Competition was held, with 28 central enterprises sending players and 11 foreign teams. In this competition, Liu Hongguang performed the stunt "blind welding". In the end, Liu Hongguang won the praise of foreign judges with his impeccable performance. Several Russian experts were very interested in his blind welding technology, and kept taking pictures of his English operation introduction with their cameras. For Liu Hongguang, a short performance of 10 minutes condensed his first-line welding practice and innovation for more than 20 years.

Skill inheritance, master studio transmits skills and brings talents.

In 2015, the factory established the "Liu Hongguang Skills Master Studio" named after Liu Hongguang. In 2016, Liu Hongguang Skills Master Studio was selected as the first batch of employee innovation studios in the national defense post and telecommunications industry in Inner Mongolia Autonomous Region. After the establishment of the studio, Liu Hongguang’s work became busier. In addition to doing his own job well, he took the inheritance of skills as another important mission. After using his work, he put every technological innovation into words for colleagues in the studio to learn and communicate. Over the years, the summary of all aspects has accumulated nearly 100 thousand words.

With the help of the studio platform, we organized many activities, such as the exhibition of skilled talents’ unique skills, the "Maker Salon" for employees, the promotion of innovative achievements, and technical research. Master Liu Hongguang’s studio has achieved hardware, team, projects and achievements, and has become an "innovative home for employees" that plays the role of model workers, unites the strength of employees, cultivates innovative spirit, incubates innovative achievements and guides employees to innovate and create efficiency.

In many years’ work, Liu Hongguang has trained 1 welder stunt technician, 2 senior technician successors, 2 technicians and 7 senior workers in China Aerospace Science and Industry Group through various forms such as mentoring and technical guidance.

After 27 years of persistence, we have left a series of solid footprints: national technical expert, national "youth post expert", Inner Mongolia Autonomous Region "excellent youth post expert", "central enterprise youth post expert", chief technician of group company, and "Top Ten Youth" of Sixth Hospital & HELIP; … "For a complete solid rocket engine shell, welding is only one of the unobtrusive links, but if there is a problem with the accuracy of this link, the consequences will be unimaginable." Liu Hongguang said seriously. (Source: China National Defense Posts and Telecommunications Union)

Beijing Youth Daily-Knowing the news of WeChat WeChat official account, on November 25th, Committee member the Political Bureau of the Communist Party of China (CPC) Central Committee and Liu He, Vice Premier of the People’s Republic of China published a signed article in People’s Daily-"Accelerating the Construction of a New Development Pattern with Domestic Macrocycle as the Main Body and Domestic and International Dual Cycle Promoting each other".

The article mentioned, "It is necessary to adhere to the positioning that houses are used for living, not for speculation, adhere to both renting and purchasing, and improve the long-term rental policy to promote the stable and healthy development of the real estate market.. "

Zheng Zhijun noticed that recently, including Liu He, two The Politburo Standing Committee (PSC) and four members of the Political Bureau of the Communist Party of China Central Committee published signed articles in People’s Daily:

On November 18th, The Politburo Standing Committee (PSC) and Li Keqiang, Premier of the State Council of the People’s Republic of China published an article entitled "Guiding Principles for Economic and Social Development during the Tenth Five-Year Plan".

On November 19th, The Politburo Standing Committee (PSC) and Han Zheng, Vice Premier of the State Council of the People’s Republic of China published an article: "The long-term goal of basically realizing socialist modernization by 2035".

On November 20th, members of the Political Bureau of the Communist Party of China Central Committee, Secretary of the Secretariat of the Central Committee, Director of the General Office of the Central Committee and Director of president Office published an article: "Insist on and Improve the System and Mechanism of the Party Leading Economic and Social Development".

On November 23rd, members of the Political Bureau of the Communist Party of China Central Committee, Secretary of the Secretariat of the Central Committee and Minister of Propaganda Department of the Central Committee Huang Kunming published an article: "Promoting the Construction of a Powerful Socialist Culture". On November 24th, members of the Political Bureau of the Communist Party of China Central Committee and Wang Chen, Vice Chairman of the Standing Committee of the National People’s Congress published an article: "Promoting the Self-improvement and Development of Socialism with Chinese characteristics’s Political System".

On November 25th, members of the Political Bureau of the Communist Party of China Central Committee and Liu He, Vice Premier of the People’s Republic of China published an article: "Accelerating the construction of a new development pattern with domestic macro-cycle as the main body and domestic and international dual-cycle promoting each other".

These articles have revealed many signals.

Each has its own emphasis.

From the content point of view, the above six articles are all intended to "study and implement the spirit of the Fifth Plenary Session of the 19th CPC Central Committee".

But the focus is different.

Among them, Li Keqiang, Premier of the State Council of the People’s Republic of China, as well as Vice Premier Han Zheng and Liu He of the State Council, all focused on economic issues.

Ding Xuexiang, director of the General Office of the Central Committee, put forward requirements for leading cadres at all levels in the article; Huang Kunming, Minister of Publicity Department of the Communist Party of China, focused on "building a strong socialist cultural country"; Wang Chen, Vice Chairman of the Standing Committee of the National People’s Congress talked about "Socialism with Chinese characteristics’s political system".

Each of these articles is worthy of serious study and reading. Today, Zheng Zhijun wants to focus on two points, one is economic issues, and the other is leading cadres.

economy

Look at the economy first.

Li Keqiang’s article focuses on the guiding principles of economic and social development during the Tenth Five-Year Plan period, Han Zheng talks about "basically realizing the long-term goal of socialist modernization by 2035", and Liu He talks about "accelerating the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other".

Li Keqiang believes that under the complicated and changeable international economic and political situation, for such a large economic volume, in a certain sense,Steady is progress..

Han Zheng mentioned innovation.

"The problem of insufficient development imbalance in China is still outstanding, and the task of reforming key links in key areas is still arduous, especially the innovation ability does not meet the requirements of high-quality development.The situation that key core technologies are controlled by people has not been fundamentally changed. Many fields, such as high-end chips and basic components, are stuck in the neck. Under the situation that the development of science and technology is facing external repression and containment, it is urgent to speed up the pace of independent innovation.. "

Liu He, who published today, focused on "fully implementing the decision-making and deployment to accelerate the construction of a new development pattern".

Liu He mentioned the current domestic and international background at the beginning of the article.

He wrote, "The world today is experiencing a great change that has never happened in a hundred years. China’s development is still in an important period of strategic opportunities, but there are new developments and changes in both opportunities and challenges.Many of the problems we encounter are long-term and many of them have never been experienced before, so we need to deepen our understanding and deal with them effectively from a strategic perspective.. "

Liu He believes that building a new development pattern is a development issue, but it is essentially a reform issue.

"We must use reform thinking and methods to form a dynamic market subject, establish an effective incentive mechanism and create an institutional environment to encourage innovation.Remove the system, concept and interest fetters that hinder the smooth flow of the domestic big cycle and the domestic and international double cycle.”。

Liu He’s article also talked about "scientific and technological innovation", "supply creates and leads demand", "finance better serves the real economy", "new urbanization and coordinated development between urban and rural areas" and "expanding employment and raising income level".

Some details are also worth pondering.

Zheng Zhijun noted that Liu He mentioned in the article that investment should play a key role in optimizing the supply structure, expand the investment space, optimize the investment structure, and promote the equipment renewal and technological transformation of enterprises.Promote the construction of a number of major projects with strong foundation, increased functions and long-term benefits..

Liu He believes that the real estate industry affects investment and consumption, which is related to people’s livelihood and development.

"insist on it.The house is for living, not for speculation.ofPositioning, adhere to both rent and purchase, and make policies according to the city.Improve the long-term rental policyTo promote the stable and healthy development of the real estate market. "

The Party’s Leadership over Economic and Social Development

"Party, government, military and civilian studies, east, west, north and south, the party is leading everything.Strengthen the party’s leadership over economic and social development, is the proper meaning of upholding the party’s overall leadership. "

On November 20th, members of the Political Bureau of the Communist Party of China Central Committee, Secretary of the Central Secretariat, Director of the General Office of the Central Committee and Director of president Office Ding Xuexiang issued a document.

In the article, Ding Xuexiang mentioned that the more severe and complicated the situation is, the more contradictory risks and challenges are increasing, and the stronger the leadership core is, the more stable and far-reaching the economy and the social stability and harmony are ensured.

Zheng Zhijun noticed that Ding Xuexiang also talked about some current problems in his article.

He wrote that at present, the implementation of the "two maintenances" in the economic and social fields is generally good, but there are also some noteworthy problems:

Some people think that "two maintenance" is mainly a matter of political attitude and has little to do with the specific work of economic and social development.

Some express their views on the decision-making and deployment of the CPC Central Committee quickly and with high tone, butWhen local interests, departmental interests, overall interests and overall interests conflict, when the requirements of the central authorities are inconsistent with their own customary thinking and practices, they hesitate and are not determined enough to implement them, and even engage in "policies from above and countermeasures from below" in a different way.

Ding Xuexiang believes that all these problems should be prevented and corrected.

This article also puts forward requirements for leading cadres at all levels, such as:

It is necessary to enhance the courage of innovation, dare to be the first to eat crabs, and not stick to the old ways and stand still.

In-depth study of major issues in the economic and social fields, on how to accelerate the cultivation of a complete domestic demand system, how to accelerate the self-reliance of science and technology, how to promote the optimization and upgrading of industrial chain supply chain, how to promote the modernization of agriculture and rural areas, how to improve people’s quality of life, how to firmly hold the bottom line of safe development, etc., comprehensively understand the situation and find the key points.Think clearly about the countermeasures

To strengthen the economic security risk early warning, prevention and control mechanism and capacity building, to achieveImportant industries, infrastructure, strategic resources, major science and technology and other key areas are safe and controllable.

Ding Xuexiang also wrote that to coordinate development and safety, we should not only put the weight on safety and put development in a secondary position, but should give more consideration to safety factors in development and strive to promote high-quality development while ensuring safety.

“It is wrong to ignore potential risks and challenges for development; It is also wrong to hold back on development for safety.. "
