Great country craftsman： Li Shugan, a worker inventor of cutting-edge bearing technology

Picture default title

　　International Online Report (Reporter Li Meng): The interview of "Chinese Dream-Great Craftsman" was transferred from Benxi to Wafangdian on the 28th. The interviewee of this trip is Li Shugan, a maintenance electrician of Wafangdian Bearing Group Co., Ltd. (Wazhou). Why did you choose him? Because Li Shugan is the kind of person who has studied, carried forward and passed on the craftsman spirit for decades, he has solved many difficult problems in the field of bearing manufacturing heat treatment in China with his diligence and wisdom, and is known as "the worker inventor who dares to challenge the cutting-edge technology of the industry".

　　What are bearings for? What kind of enterprise is Wazhou? In Li Shugan’s words, running on the ground, flying in the sky and swimming in the water are all inseparable from rotation, and as long as there is rotation, there will be bearings. "We all know ‘ Liaoning ’ The aircraft carrier, when its carrier aircraft lands on the deck, will have a steel cable to hook it. The bearing used in this steel cable is made by us. " Wazhou Company, however, is the only super-large state-owned enterprise left in China bearing industry at present, and its history can be traced back to 1938. In addition, the reporter also saw that the military representative office of our Air Force, Navy and General Armament Department in Dalian is located in this company.

　　Li Shugan is a national model worker in 2015, a winner of the National May 1st Labor Medal, an expert enjoying special government allowance, the leader of the national Li Shugan Skills Master Studio, and the leader of the first "Li Shugan Demonstration Model Worker Innovation Studio" in Dalian … … Of course, there are many, many honors.

　　Li Shugan has been engaged in electrical debugging and maintenance of major precision imported production equipment for a long time. He is good at digesting and absorbing the high-end technology of imported equipment, and is good at quickly diagnosing and eliminating difficult faults of electrical equipment. His skill level is superior, and he is recognized as an electrical maintenance expert and praised by many colleagues at home and abroad.

　　Engaged in electrical maintenance for more than 40 years, he has solved more than 300 production equipment problems, reformed more than 150 sets of equipment, completed more than 270 technical innovations, and repaired several sets of equipment, which effectively guaranteed and improved the quality of bearings and created tens of millions of economic benefits for enterprises.

　　Give a specific example to illustrate. In the rapid development of China’s high-speed railway, Wazhou Group Company undertakes the heavy responsibility of R&D and manufacturing of railway speed-increasing bearings, and the heat treatment process once became a "bottleneck". Li Shugan and other technical experts of the company undertook the development task of quenching press. He took the initiative to undertake the research and development design of the new machine tool circuit, and innovated the static quenching of the machine tool into dynamic rotary quenching, which increased the hardness of the core of the railway speed-increasing bearing by 25%, reduced the deformation of the product by 30%, and achieved a leap in the heat treatment quality of the railway speed-increasing bearing.

　　Li Shugan proved that precision high-end bearings can not only be "made in China", but also be "created in China". This self-developed equipment can replace imported machine tools, saving 12 million yuan in purchase funds. This technical achievement won the "National Excellent Technical Achievement Award for Employees".

　　However, Li Shugan is far from satisfied with this. He said frankly, "In fact, there are no bearings on high-speed trains in our country at present. The relevant departments have set up a project team to study the independent manufacture of high-speed train bearings. Wazhou Group is one of the members of this project team, and Wazhou is working hard to this goal."

　　In 2010, a multifunctional carburizing electric furnace heating actuator imported from Germany in Wazhou Company was burnt out. German experts insisted on replacing the original parts, but it needed to be imported from abroad, and the production and market could not wait. Li Shugan relied on his own ability to absorb and digest the imported technology and boldly selected domestic parts to repair it, so that German experts had to give a thumbs up to China workers. Later, together with German experts, he optimized the operation program of electric furnace to a higher level, which prolonged the service life of heating actuators and saved 300,000 US dollars in foreign exchange.

　　Li Shugan has also made two outstanding contributions to technological innovation and invention. One is called "electric furnace running beat controller", which can automatically control the running beat of electric furnace according to the technological requirements of products, improve product quality, improve equipment efficiency by more than 65%, and automatically feed back information for equipment maintenance, effectively reduce the failure rate of electric furnace by more than 85%, and save production funds and maintenance costs for enterprises by 3.5 million yuan every year.

　　The other is called "heating control method of carburizing electric furnace". The traditional temperature control method often leads to the damage of electric furnace heater and short service life. The new invention has overcome this technical difficulty, improved the working efficiency of electric furnace, and saved 1.2 million yuan in electrical material cost for enterprises every year.

　　Li Shugan, born in 1955, has reached retirement age. As the leader of the national skill master studio, he has long insisted on teaching technology to young workers, and compiled his reading notes, maintenance experience and unique skills for more than 30 years into training materials, and taught them to young workers without reservation.

　　"The core task of this studio is training, because only through training can the technology be passed down like a baton." Nowadays, among Li Shugan’s more than 30 apprentices, there are both workers and college students, all of whom have become technical backbones of enterprises, and some have become highly skilled talents.

Expert： China is getting closer to the center of the world stage.

　　In the report of the 19th National Congress of the Communist Party of China, General Secretary of the Supreme Leader put forward a far-sighted judgment that "Socialism with Chinese characteristics has entered a new era", which has both a world outlook and a methodology, and also reflected China’s diplomacy and international relations. The report pointed out that this new era is an era when China is approaching the center of the world stage and making greater contributions to mankind.

　　In the five years since the 18th National Congress of the Communist Party of China, China has comprehensively promoted the diplomacy of a big country with China characteristics, and constantly approached the center of the world stage, which means that the diplomacy of a big country with China characteristics should make a difference. The greater the ability, the greater the responsibility. In his report, the Supreme Leader General Secretary put forward new requirements for China’s diplomacy, and made it clear that the diplomacy of a big country with China characteristics should promote the construction of new international relations and a community of human destiny.

　　Socialism with Chinese characteristics entered a new era and contributed China wisdom and China plan to solve human problems. "China Wisdom" is some diplomatic principles, norms and standards that China has been practicing since the founding of New China, and it also contains the essence of China’s traditional culture, such as harmony without difference, don’t do to others what you don’t want them to do to you, and the world is one. The "China Plan" refers to the application of China’s wisdom and foreign policy principles to put forward China’s plan on the common problems faced by all mankind, to promote the construction of a new type of international relations featuring mutual respect, fairness, justice, cooperation and win-win, and to promote the building of a community of human destiny.

　　It can be seen that the diplomacy of a great country with China characteristics in the new era not only has a global vision and enterprising spirit, but also is more open and inclusive, showing the world feelings that the Communist Party of China (CPC) people have always maintained, not only to solve their own affairs, but also to make contributions to all mankind. As General Secretary of the Supreme Leader said in the report of the 19th National Congress of the Communist Party of China, "it provides a brand-new choice for countries and nations in the world who want to accelerate their development and maintain their independence".

Expert explanation：＂12345＂ of China-Pakistan Economic Corridor

　　Wang Yiwei Senior Research Fellow, Chongyang Financial Research Institute, Renmin University of China, and Senior Research Fellow, Chahar Institute.

　　Moody’s, an internationally renowned credit rating agency, recently commented that the China-Pakistan Economic Corridor project has obviously promoted Pakistan’s economy. Driven by the China-Pakistan Economic Corridor, Pakistan’s economy is expected to maintain a growth rate of 5% in the next two years.

　　For Pakistan, the China-Pakistan Economic Corridor is a real project, bearing the heavy responsibility of economic take-off and even national rise. For China, this project will help to promote regional interconnection and promote the common development and prosperity of regional countries.

　　This is the supporting dock facilities of Hubu coal-fired power plant under construction, which was photographed by drone in Hubu area of Balochistan province, Pakistan on March 21, 2017. China Electric Power International Co., Ltd. participated in the construction of the Hubu coal-fired power station project, and held a groundbreaking ceremony in Hubu District, Balochistan Province on the 21st. This marks the official groundbreaking of another large-scale energy project in the China-Pakistan Economic Corridor. The construction contents of the project mainly include power plants and special coal terminals, with a planned total installed capacity of 1,320 MW. After the project is completed and put into operation, it can supply 900 million kWh of electricity every year, meeting the electricity demand of 4 million households in Pakistan.

　　China-Pakistan Economic Corridor: The Sweet Opening Song of the Symphony "Belt and Road"

　　The China-Pakistan Economic Corridor starts in Kashgar, Xinjiang, and ends in Gwadar Port, Pakistan, with a total length of 3,000 kilometers. It is connected to the Silk Road Economic Belt in the north and the 21st Century Maritime Silk Road in the south. It is a key hub connecting the North and South Silk Roads and a trade corridor including roads, railways, oil and gas and optical cable channels. Regarding this "flagship project" of the Belt and Road Initiative, Foreign Minister Wang Yi once said: "If we say ‘ Belt and Road ’ If it is a symphony that benefits many countries, then the China-Pakistan Economic Corridor is the sweet opening song of this symphony. "

　　In April 2015, the Chinese and Pakistani governments initially formulated a long-term plan to build a "four-in-one" channel covering roads, railways, oil and gas pipelines and optical cables from Kashgar, Xinjiang to Gwadar Port, the southwest port of Pakistan. China and Pakistan will build transportation and power facilities along the route. It is estimated that the total project cost will reach 45 billion US dollars, and it is planned to be completed in 2030.

　　On April 21st, 2015, the Supreme Leader of president delivered an important speech entitled "Building a Community of Destiny between China and Pakistan and Opening a New Journey of Win-Win Cooperation" in the Pakistani Parliament. In his speech, President Xi pointed out that the China-Pakistan Economic Corridor is an important starting point for China and Pakistan to achieve common development. We should give full play to the leading role of corridor construction in pragmatic cooperation between the two countries, and form a "1+4" cooperation layout with corridor construction as the center and Gwadar Port, energy, infrastructure construction and industrial cooperation as the focus. Corridor planning and layout should take into account all regions of Pakistan, so that the fruits of development can benefit all people in Pakistan, and then benefit the people of all countries in the region.

　　"12345" of China-Pakistan Economic Corridor

　　The connotation and trend of China-Pakistan Economic Corridor can be summarized by "12345".

　　A corridor:That is, the China-Pakistan Economic Corridor, which is the flagship corridor of the six economic corridors of the Belt and Road Initiative.

　　Two countries:The China-Pakistan Economic Corridor is a symbol and sublimation of the friendship between China and Pakistan.

　　Three stages:The construction of China-Pakistan Economic Corridor is mainly divided into three stages. The early stage is from 2013 to 2020, focusing on energy and infrastructure construction, which is the premise of industrialization, like building a house and laying a foundation. The medium-term stage is from 2021 to 2025, which is the take-off stage of industrialization, just like building a building. The long-term stage is from 2025 to 2030, and the construction focuses on culture, finance, tourism, trade, industry and commerce, transportation and other fields, such as interior decoration of buildings. At present, Pakistan has basically completed the long-term corridor planning.

　　Four pillars:The four pillars of the China-Pakistan Economic Corridor include energy such as electricity, infrastructure such as roads, railways, air routes, oil roads and information superhighways, Gwadar Port and Karachi Export Processing Zone.

　　Five major effects:First, the demonstration effect of China-Pakistan cooperation: encouraging more countries to learn from the China model; The second is the industrial transfer effect, realizing the third wave of Asia’s rise; Third, the north-south balance effect: connecting Eurasia (with Xinjiang as the core) with the Indian Ocean, realizing the great balance between the north and the south, and realizing geopolitics — Geo-economy — Logical transfer of geo-civilization; Fourth, the regional cooperation effect of Greater South Asia: through the cooperation of China, Pakistan, Afghanistan, China, Pakistan and India, the spillover effect of China-Pakistan economic corridor will be realized, which will serve the trinity of "development, security and governance" and attract foreign countries to participate and form an international cooperation demonstration; Fifth, the global governance effect, through pragmatic cooperation between China and Pakistan, to solve Pakistan’s "long-term poverty — Tribal violence — The vicious circle of terrorist attacks.

　　Confucius said, "If you want to stand and be a man, you want to reach and be a man.". The China-Pakistan Economic Corridor is the flagship corridor of the Belt and Road Initiative. It undertakes the mission of extending China’s industrial chain, helping Pakistan realize industrialization, modernizing its national governance capacity and governance system, and jointly building a community of destiny between China and Pakistan.

Dangerous and immoral experiment! 122 experts approve the British ＂unblocking＂ plan

　　BEIJING, July 9 (Xinhua) According to foreign media reports, the British government recently announced the details of the final phase of the "unblocking" plan in England, so that the economy can be restarted as soon as possible. However, at present, the number of confirmed cases in COVID-19 is still high. More than 100 scientists and medical experts recently published an open letter in the authoritative medical journal The Lancet, criticizing the authorities for lifting all restrictions, which is like conducting a "dangerous and immoral experiment".

　　On July 5, local time, British Prime Minister David Boris Johnson announced a series of measures to unblock the next stage at the press conference of the Prime Minister’s Office, including: the restrictions on the number of indoor and outdoor parties in England were cancelled; The bar reopened; The requirement to keep a social distance of one meter was cancelled; Masks are not mandatory, and the rules for working at home are cancelled. The government will evaluate these measures in a week and finally decide whether to implement them from the 19th of this month.

　　In this regard, as many as 122 scientists and medical experts, including the Chairman of the Board of Directors of the British Medical Association, the head of SAGE, and scientists from Oxford University and University College London, signed an open letter criticizing the decision to lift the epidemic prevention restrictions as "hasty and immature" and saying that any strategy that can tolerate high levels of infection is "illogical".

　　Nagpaul said that the number of confirmed cases in Britain is soaring. Although the relationship between confirmed cases and hospitalization and death has weakened, it has not been cut off. At present, the number of patients who need to be hospitalized and use ventilators due to Covid-19 infection has doubled compared with the same period of last month. He also mentioned that about 1 in 10 patients had sequelae of "long new crown", and as many as 2 million people still felt unwell after more than three months, but the government deliberately played down the seriousness of "long new crown".

　　"We know that masks can effectively prevent the spread, so it is absurd and dangerous for the government to cancel the mandatory wearing of masks in indoor public places such as public transportation from July 19."

　　Many joint experts are very worried about the issue of "long new crown", pointing out that its impact can last for months or even years. Strang, a senior clinical lecturer at the University of Exeter and a coronavirus researcher, said that many people in the scientific community urged Dzhavid, the new British health minister, to consider the long-term Covid-19 problem when evaluating the unsealing.

　　Dr. Gu Erda Sani, a senior lecturer and epidemiologist at Queen Mary University, said: "The government intends to expose children to large-scale infections, not to protect them or vaccinate them in schools." This is immoral and unacceptable. "Our young people have suffered so much in the past year, and now they have to bear the consequences of this dangerous experiment."

　　Horton, the editor-in-chief of The Lancet, supported the opinion of the co-signers, pointing out that contrary to what the British government scientists said, there is still no consensus on the comprehensive lifting of epidemic prevention measures in Britain, and many scientists are opposed to the decision. "Many scientists are very worried that the proportion of people who have completed vaccination is not ideal at present, and the infection rate is rising rapidly. We are at a very dangerous moment of pandemic."

　　Corey, an epidemiologist at Imperial College London, believes that it is too early to claim that it can coexist with the virus. Delaying the lifting of restrictions will give the authorities more time to stop the spread of the virus, including vaccinating people with booster vaccines and injecting children.

　　On July 7th, local time, WHO held a regular press conference in COVID-19. Michael Ryan, the head of WHO’s health emergency project, said that countries should be extra careful now. Although the number of hospitalizations and new deaths in many countries began to decrease, the number of new cases increased in many regions around the world last week. In Europe, for example, the number of new cases increased by 33%.

　　Ryan stressed that the current epidemic curve is not flat, but in a state of growth, and it cannot be wrongly assumed that the spread of the virus will not increase again. Ryan called on governments all over the world to hold on to the achievements made in fighting the epidemic and open their societies cautiously.

Can palpitation cause sudden death？ Don’t panic, it’s different!

　　Palpitation is a kind of physical discomfort that we often encounter. It can be manifested as "the heart is jumping fast", it can be "the heart is empty", it can also be "feeling flustered in the heart", or "being all over and fidgeting" and so on. Especially when winter comes, the incidence of cardiovascular and cerebrovascular diseases is high, and then it is a "panic group". Don’t worry, the doctor told you that you are a little flustered and don’t worry.

　　Sudden death is often caused by a heart attack.

　　Is palpitation a serious heart disease? Will it cause sudden death like some stars? Many flustered patients will have such worries.

　　In fact, most of the causes of sudden cardiac death are often acute myocardial infarction, commonly known as acute myocardial infarction. Acute myocardial infarction is generally caused by acute occlusion of the coronary artery supplying blood to the heart. Palpitation, on the other hand, is an electrical change that is responsible for stimulating and maintaining the heartbeat. The two are very different. Is the so-called electrical palpitation very serious? Compared with acute myocardial infarction, the disease that leads to palpitation is much lighter. If you want to know the harm of palpitation, you must know what happened to your heart when you were flustered.

　　The feeling of palpitation comes from the change of heart rate and rhythm. For example, the heartbeat is particularly fast, particularly slow, and the jump is irregular, which will lead to palpitation. In the three cases, there is no need to worry about some fast and irregular heartbeats.

　　This sudden heartbeat is nothing serious.

　　First of all, some rapid heartbeats are physiological, so there is no need to worry. For example, students are nervous during exams, climb mountains very hard, and are very annoyed when they are angry, all of which will lead to an end, that is, sympathetic excitement. The activities of the human body are finely regulated by the sympathetic and parasympathetic nervous systems to achieve a balance. Sympathetic nerve excitation can cause rapid heartbeat, rapid breathing and high blood pressure; On the other hand, parasympathetic nerve excitation is just the opposite, which makes people’s heartbeat slow, breathing slow, blood pressure drop, etc., such as sleep state.

　　Sometimes, when I have a nightmare at night, my heart beats very fast when I wake up, because my body is in a state of extreme sympathetic excitement in my dream. The rapid heartbeat in these cases is an adaptive adjustment made by the human body to meet the needs of the environment and body functions. When you are no longer nervous, tired or angry, your heartbeat will be better. It’s not good if you force medication to keep your heartbeat down.

　　There is no need to worry about sympathetic nerve excitement caused by physiological reasons, resulting in accelerated heartbeat or premature arrhythmia.

　　In this case, you can take some medicine as appropriate

　　In addition to emotional factors such as anger, labor, tension, etc., exciting drinks such as drinking, tea, coffee, etc. can also lead to sympathetic excitement, which leads to palpitation. These conditions are also caused by physiological factors, that is, the influence of food. Under normal circumstances, there is no need to worry and there is no need to use drugs.

　　Some patients never drink alcohol, and the palpitation caused by occasional drinking may last for a long time and always be uncomfortable. In this case, some drugs that inhibit sympathetic neurotransmitters can be used appropriately, such as beta1 receptor blocker — — Metoprolol, wait.

　　Some palpitations are not rooted in the "heart"

　　Some cases are pathological, but the disease itself is not in the heart, but in other systems of the whole body. For example, when diabetic patients have hypoglycemia, they will show palpitation caused by rapid heartbeat and discomfort such as shaking hands and sweating. At this time, it is not simply to reduce the heart rate, but to solve hypoglycemia. If you can take high-sugar foods such as chocolate, candy and biscuits, you will quickly improve palpitation. Another example is cervical spondylosis, which can also lead to palpitation, manifested as long-term desk work or sudden stress on the neck, such as palpitation, dizziness, sweating, nausea, and even chest tightness. At this time, there is no need to rush to use drugs to reduce the heartbeat, but to improve the environment of the neck. For example, doing actions such as raising your head and whistling, watching a play through a partition wall, or doing exercises of the muscles of the shoulder and neck to improve the strength distribution of the muscles attached to the cervical spine; Anemia can also lead to palpitation. The first manifestation is a rapid heartbeat, often accompanied by shortness of breath and chest tightness after activities. At this time, blood tests are needed to determine; Similarly, abnormal thyroid function will also lead to palpitation, and the diagnosis also requires blood tests.

　　Need to remind everyone that after excluding the factors mentioned before, if you still have palpitation and can’t find the reason, you should go to the hospital in time to find out the reason. It is the most important thing to treat the cause.

AITO asks about the upcoming appearance of the medium and large SUV M8, and the space is upgraded to a bright spot.

The M8, the latest medium and large SUV built by AITO, may meet the public soon. Judging from the renderings, the shape design of M8 reminds people of Land Rover Range Rover, which also reminds people of the success of Xiaomi SU7 by "paying tribute" to the shape of Porsche Taycan.

Compared with the M7, its wheelbase is only 2.82 meters, which makes the third row space of the 6-seat version narrower. However, as can be seen from the spy photos, the body size of M8 is obviously larger than that of M7, and the wheelbase is expected to exceed 3 meters. It is expected that the space in the third row will be significantly improved.

In the current market, the two most popular domestic brands of large SUV——, Ideal L9 and Wenjie M9, both provide extended-range power versions, and they are all six-seat models, and the third row space can completely rival the MPV of the same level. It is expected that the M8 will also provide extended-range models. Combined with its spacious cockpit space, the sales prospect is highly anticipated.

The introduction of M9 has already impacted the market position of Ideal L9. At the same time, the world M7 also performed well in the competition with the ideals L7 and L6. If the listed price of M8 is competitive, it will put great pressure on the ideal L8 with similar positioning.

Wenjie M8 is expected to adopt the embracing cockpit design, and be equipped with high-end configurations such as Shuyun double-seat, zero-gravity seat, dual wireless mobile phone fast charging and Huawei self-developed hi-fi audio. Referring to the M9, the M8 may also be equipped with air suspension, CDC variable damping shock absorber and intelligent four-wheel drive system to further improve ride comfort and driving stability.

After three years of collecting and collecting cardiac stents, more than 3.7 million patients have benefited, and the burden of medical treatment has been significantly reduced.

CCTV News:Cardiac stent implantation is an important measure to treat acute myocardial infarction. Before centralized procurement, the average price of cardiac stents was as high as 13,000 yuan, and the price of imported stents was close to 20,000 yuan. The masses strongly reflected the high price. In January, 2021, cardiac stents were collected, and the average price dropped to 700 to 800 yuan. In the past three years, more than 3.7 million patients have been implanted with the selected cardiac stent, accounting for more than 95% of the cardiac stent usage.

Mr. Xianglin, who is over 80 years old this year, is the first patient in Hunan Province to use the national centralized coronary stent. In the early morning of January 1, 2021, Xianglin suffered an acute myocardial infarction and was rushed to the First People’s Hospital of Xiangtan City by her family. Then the doctor performed a cardiac coronary stent implantation for her, each stent was 798 yuan. More than three years later, when the reporter saw Xianglin again, the living conditions of the elderly were still good.

At present, the First People’s Hospital of Xiangtan City carries out more than 400 cardiac and coronary stent implantation operations every year. More and more patients have used the price-reduced stents, and the burden of myocardial infarction treatment has been significantly reduced.

Lu Bangfu, chief physician of the first ward of Cardiology Department of Xiangtan First People’s Hospital, Hunan Province, said that the average cost for a patient to have a stent (implantation operation) before the collection is at least 30,000 to 40,000. At present, the total cost, including radiography, only costs more than 13 thousand, and the patient only pays about 6 thousand to 7 thousand yuan after medical insurance reimbursement.

According to the provisions of the National Medical Insurance Bureau, all localities can retain the medical insurance funds saved by the centralized procurement of cardiac stents by medical institutions according to a certain proportion, so that medical institutions and medical personnel can share the reform dividend.

Wu Yongjun, vice president of the First People’s Hospital of Xiangtan City, Hunan Province, said,After the expenses (surplus funds) are returned to the hospital through the method of surplus retention, we return them to the clinical medical team through the examination, which reflects the labor value of medical staff. After turning into income under the sun, the enthusiasm of the whole medical service team to serve the people is also obviously enhanced.

Improve the interventional operation ability of primary medical institutions

Cardiac stent implantation is an important measure to treat acute myocardial infarction. Coronary artery is the blood vessel that supplies blood to the heart. Once stenosis occurs, myocardial blood supply is insufficient, which will seriously lead to myocardial necrosis, affect cardiac function and even endanger life. For patients, time is life. With the collection of cardiac stents and the reduction of consumables prices, more and more primary medical institutions can carry out such operations more conveniently.

At Shuangfeng County People’s Hospital in Loudi City, Hunan Province, He Weidong, 54, comes for a follow-up visit every three months. In January, 2022, He Weidong was rushed to hospital by his family for persistent chest pain. After being diagnosed with acute myocardial infarction, the doctor immediately performed heart stent implantation. However, in the past, medical institutions in Shuangfeng County were unable to carry out such operations because of insufficient hardware and expensive cardiac stents, and patients with acute myocardial infarction could only be transferred to higher-level hospitals.

Wang Gang, executive vice president of Shuangfeng County People’s Hospital, said that when patients with acute myocardial infarction could not undergo interventional surgery on our side, they had to go to places like Loudi (city) and Changsha (city), and the journey might take one or two hours. The risks on the road and the recovery of the final patients were very unfavorable.

In August 2021, the Interventional Medical Center of Shuangfeng County People’s Hospital was established, which was also the first medical institution in the county to carry out such first aid.

Wang Gang, executive vice president of Shuangfeng County People’s Hospital, said that due to the centralized mining policy (landing), the stent is so cheap, and the pressure on the hospital is also very small, and the pressure on the people is also very small. We are now able to carry out stent surgery 24 hours a day. For patients with acute myocardial infarction, our rescue success rate, patient recovery and recovery have been greatly improved.

The reporter learned from the National Medical Insurance Bureau that nationwide, after the centralized procurement, the number of medical institutions carrying out cardiac stent implantation increased from more than 2,400 in 2020 to more than 3,600 in 2023, among which the number of secondary medical institutions increased from 1,200 to nearly 1,700, which is inseparable from the efforts of health departments to strengthen the capacity building of county-level chest pain centers in recent years. Patients with acute myocardial infarction can have stent implantation in more county hospitals, and get back more precious rescue time in the race to save lives.

Starting with the ＂single structure＂, we should point out the revitalization of Northeast China.

　　Editor’s note:In the past two years, the economy of Northeast China has fallen into weakness, and foreign media have written one observation and comment article after another about the economic malaise in Northeast China, which has broken the heart for the black land thousands of miles away. What happened to the northeast economy? How to do a new round of economic revitalization in Northeast China? In order to answer these questions, from January 9 to 14, the theme activity of "Directly Attacking Northeast Economy" directed by the Central Network Information Office was launched simultaneously in Liaoning, Jilin and Heilongjiang. A joint interview group composed of online media and authoritative experts went to the three northeastern provinces for field research to solve the "new prescription" of the northeast dilemma. Guangming. com published the third series of expert manuscripts on "Directly Attacking Northeast Economy" for readers.

　　Authors: Sun Jiuwen, School of Economics, Renmin University of China; Yao Peng, Institute of Industry and Economics, Chinese Academy of Social Sciences; Hu Hengsong, Hebei Institute of Finance.

Starting with the "single structure", we should point out the revitalization of Northeast China.

　　In recent years, Northeast China, Shanxi, Hebei and other "single structure" areas, the economic growth rate has declined, the fiscal revenue has declined, and development is difficult. This development in Northeast China is a typical "depression disease".

　　The reason of "depression disease" is that the industrial structure is single.

　　The economic decline in Northeast China in recent years is closely related to the "single structure" of industries in Northeast China. The "single structure" in Northeast China is characterized by the dominance of energy and raw materials industries, and the imperfect development of modern manufacturing and modern service industries. Due to the oversupply of bulk products in the world, it affects the production of domestic bulk products industry, and all areas with heavy industrial structure have experienced different degrees of speed decline. Therefore, although there are many reasons for the economic downturn in Northeast China, the "single structure" of the industry is undoubtedly one of the important reasons.

Starting with the "single structure", we should point out the revitalization of Northeast China.

　　The emergence of a single region with industrial structure is not accidental, but has profound historical and theoretical reasons. Theoretically, for a certain aspect of development theory — — The excessive emphasis on the theory of professional development has caused disastrous consequences; From the development mode, the planned economy after the founding of New China copied the former Soviet Union. The former Soviet Union advocated regional specialization and "a game of chess in the whole country". Every region is a specialized region, and only by cooperating with other regions can its own development be guaranteed. After the disintegration of the Soviet Union, the retrogression of the economies of the former participating republics is an outcome of this specialized production. China’s industrial layout is not entirely the former Soviet model, but the northeast and other regions have still laid the brand of the Soviet model.

　　Prescription 1: Introduce targeted industrial policies.

　　The "single structure" area is faced with the problem of industrial choice first, and then how to develop it. Only by grasping the order of industrial selection and development, can a single structure region enter a reasonable path in industrial transformation. Therefore, to revitalize Northeast China, we should find the root of "depression disease" and take measures against the problem of "single structure".

　　The concrete suggestions are as follows: Benxi, Liaoyang, Panjin and Chaoyang are the "single structure" cities in Northeast China; Jilin Province has Changchun City, Tonghua City, baishan city City and Baicheng City; Heilongjiang Province includes Daqing, Yichun, Jiamusi, hegang, qitaihe city, Suihua, Shuangyashan and Daxinganling. Our basic judgment is that the development of "single structure" is not a global problem, but a problem of some cities. It is necessary to introduce targeted industrial policies to revitalize "single structure" cities in Northeast China and give consideration to all aspects.

Starting with the "single structure", we should point out the revitalization of Northeast China.

　　Prescription 2:Increasing the added value of products and developing emerging industries

　　Second, the "single-structure" cities in Northeast China, except Changchun and Tonghua, are basically the main producing areas of coal, oil, grain and wood, and the main reason for their sluggish development is the impact of lower global commodity prices. Ideas for adjustment: First, maintain production capacity and reduce production scale. Through the extension and expansion of industrial chain, we can improve the depth of product processing and increase the added value and technical content of products.

　　Second, the cyclical fluctuation of commodity prices is an inevitable law of world economic development, and we need to treat depressed industries differently. Oil, grain and timber are not industries with absolute surplus, so it is necessary to maintain production capacity. Only coal has overcapacity, and "de-capacity" needs to be accelerated.

　　The third is to introduce and develop emerging industries. It is the idea of incremental development to develop emerging industries without giving up the original industries. Cultivating and promoting the development of emerging industries in these cities includes taking some strong measures to mobilize and guide the investment of various private capitals, so as to gradually form a comprehensive and diversified industrial structure.

Starting with the "single structure", we should point out the revitalization of Northeast China.

　　Prescription 3: EstablishmentThe Long-term Mechanism of "Single Structure" Regional Transformation and Development

　　The establishment of a long-term mechanism for regional transformation with "single structure" plays a certain role in promoting the transformation and development of "single structure" regions (cities), such as compensation mechanism for resource development, assistance mechanism for declining industries, and support mechanism for emerging industries. Vigorously developing small and medium-sized enterprises and small and micro enterprises is also one of the important ways to solve the problem.

　　Because most small and medium-sized enterprises are diversified industries, they are unlikely to get involved in energy and other fields. Therefore, developing small and medium-sized enterprises plays an obvious role in structural adjustment. Increase support for small and medium-sized enterprises and small and micro enterprises to promote diversified development.

Starting with the "single structure", we should point out the revitalization of Northeast China.

　　Prescription 4: Give full play to the role of the capital market

　　The role of capital is very important in the process of northeast transformation. Due to the serious heavy industrialization of industries in "single structure" areas, the capital demand for revitalizing economic development can no longer be met only through central financial support and bank loans. This requires finding new financing channels. Considering the current economic situation, only by giving full play to the role of the capital market can the development of the old industrial base in Northeast China have effective capital operation space. Make full use of the capital market’s credit policy structure adjustment and "helping the weak" function, and formulate and organize its implementation around the actual situation of the national industrial policy orientation and the revitalization of old industrial bases.

　　Prescription 5: Push hardCombination of industry and finance

　　The core function of capital market is financing. Only when capital enters the real economy and circulates can it really drive the development of regional economy. At the same time, through the causal circulation, the rapid development of the industry produces huge financing demand, which can promote the prosperity of the regional capital market. The combination of industry and finance is a way to deepen the capital market for the transformation of heavy chemical industry in "single structure" areas.

　　To successfully realize the transformation and development of the old industrial base in Northeast China, we must first solve the problem of "single structure", which requires that we must take a different path from the development of traditional manufacturing and heavy industry, and its development should rely more on the development of venture capital and financial support for heavy chemical industry. Therefore, in the face of the narrow investment and financing channels of the real economy in the old industrial base in Northeast China, it is the key to revitalize the old industrial base in Northeast China to vigorously promote the combination of industry and finance and realize the combination of virtual capital and industrial economy.

Sino-Russian agricultural cooperation continued to develop in depth.

　　International Online Report (Reporter Li Jie): Sino-Russian agricultural products trade has become one of the highlights of bilateral cooperation. In 2017, the bilateral trade volume of agricultural products exceeded 4 billion US dollars. Russia mainly exports grain, flour and seafood to China, while China mainly exports vegetables and fruits to Russia. The two countries are constantly improving the level of cooperation in agricultural investment, agricultural product processing and production.

　　In recent years, the Russian government has vigorously developed agriculture and continuously expanded the grain planting area through preferential policies. In 2017, Russia’s grain output was 130 million tons, exceeding the historical record of 127 million tons in 1978 during the former Soviet Union. While satisfying the domestic market, Russia has been the world’s largest wheat exporter for many years. Russian President Vladimir Putin has repeatedly stated that agriculture has become the locomotive of Russian economic development. "In 2000, we were heavily dependent on imported food, but now the situation has fundamentally changed. In the past four years, we began to export food to the European market, and the export volume exceeded the total import volume. Now we should increase the export of local products and deep-processed products and increase the added value. "

　　In 2017, Russian agricultural exports reached US$ 20 billion, surpassing the military industry to become Russia’s second largest industry. Putin proposed in the "May Decree" issued this year that the export of agricultural products will reach 45 billion US dollars by 2024.

　　China is the world’s largest importer of agricultural products. From July 2017 to May 2018, it imported more than 1.2 million tons of grain and food from Russia, a record high, including 840,000 tons of soybeans. Boris Dubrovski, governor of Chelyabinsk, Russia, believes that the food trade volume between the two countries has great room for improvement. "At present, our state exports flour, grain, macaroni, vegetable oil and other foods to China. Although the two sides have great development potential in the field of food trade, we hope that China enterprises will increase their direct investment in agricultural production and processing. "

　　Russia has more than 3 million hectares of arable land, and only two-thirds of the land is currently developed, which has great potential for agricultural production. China has obvious advantages in capital, technology and market. Based on this complementary advantage, China and Russia have carried out fruitful cooperation in agricultural investment and deep processing of agricultural products while optimizing the trade structure of agricultural products. Heilongjiang Province has achieved rapid development in agricultural cooperation with Russia in recent years. Wang Wentao, governor of Heilongjiang Province, said not long ago: "At present, our province has built 18 economic and trade cooperation zones in Russia. In 2017, the cooperative planting area of our province with Russia reached 8.7 million mu, and there were more than 200 enterprises engaged in agricultural development in Russia. Our province’s agricultural cooperation with Russia has formed a development trend of the whole industrial chain from planting and breeding to processing, warehousing, logistics and wholesale. "

　　According to Xing Zhiguang, deputy director of the Agriculture Committee of Heilongjiang Province, Chinese enterprises are currently planting varieties in Russia, including soybeans, corn, rice and vegetables, and are engaged in aquaculture. The two sides have continuously expanded the fields of technical exchanges and cooperation. Heilongjiang Province has established substantive cooperative relations with more than 30 Russian agricultural scientific research units and carried out in-depth cooperation in the fields of seed resource exchange and plant protection.

　　Harbin Dongjin Group, founded in 1995, has rented farmland in Khabarovsk Krai since 2017, forming a modern large-scale cross-border agricultural industry demonstration zone. Zhang Dajun, chairman of Dongjin Group, introduced that this is a large-scale industrial project integrating modern agricultural planting, breeding, processing, warehousing, port and logistics. "The project construction period is 5 years. Since 2017, the investment in equipment and capital has been 220 million yuan. The farm covers an area of 69,000 hectares, breeds 3,500 cows and has two dairy processing plants. Employ more than 200 Russian employees. "

　　Zhang Dajun introduced that the enterprise invested 170 million yuan to build an agricultural free port integrating port, warehousing, processing agriculture and logistics in Khabarovsk, with an annual storage capacity of 100,000 tons and an annual throughput of 300,000 tons of agricultural products, thus solving the transportation difficulties of Russian agricultural products exported to China and other regions.

　　Although large-scale agricultural cooperation between China and Russia has just started, it has shown great development potential and bright prospects.

Shandong Gaotang promotes agricultural socialization service to make spring ploughing more green and efficient.

CCTV News:Gaotang County, Liaocheng City, Shandong Province, vigorously promotes the socialized agricultural service based on production trusteeship, and relies on socialized service organizations to promote the green, high-quality and efficient development of agricultural production and help increase grain production and income.

At present, more than 800,000 mu of wheat in Gaotang County has entered the jointing stage, and the work of spring ploughing and spring management is in full swing. In the wheat field of Beijie Village, Zhaozhaizi Town, plant protection drones and self-propelled plant protection robots are carrying out sprinkler irrigation. Gaotang county is a traditional grain-producing county, and the planting area of grain crops has remained above 1.4 million mu all the year round.

Zhang Xiangui, Chairman of Gaotang Green Jiayuan Vegetable Planting Professional Cooperative:We will play a role as a bridge and provide intermediary services when the cooperative signs a custody agreement with the farmers door to door, and then the cooperative signs an agreement with the agricultural service company.

On this basis, the local government accelerated the construction of high-standard farmland and vigorously developed contract agriculture. Large-scale grain enterprises directly connect with trust enterprises or cooperatives, uniformly plant characteristic varieties of wheat, and implement excellent grain and excellent purchase.

Li Xuqiang, a villager from Qianye Village, Yinji Town, Gaotang County:My land used to be saline-alkali land, and the output has been unable to go up. I have no other good way. In the past two years, through the trusteeship service, their scientific and technical management of soil testing formula has almost doubled (mu yield), and I am very happy.
