Scientists develop advanced instruments to predict

Returnee scientists have developed advanced instruments that can predict stroke and myocardial infarction

the number of deaths from cardiovascular and cerebrovascular diseases in China is as high as 3million every year, accounting for half of the total deaths in China every year. Last year, Dr. lizhiyong, a returnee, came to Nanjing to start a business with his R & D product "vulnerable plaque evaluation system", which can predict stroke and myocardial infarction in advance by introducing cerebrovascular hemodynamic function detection parameters. Patients only need to go through more than 10 points. The solution is to check whether the power line connected to the experimental machine is connected normally; Check whether the emergency stop switch is screwed up; Check whether the power supply voltage connected to the experimental machine is normal; Check whether the fuse on the machine socket is a test similar to B-ultrasound. More than 80% of high-risk patients can detect it in advance, which is 75% more accurate than the existing clinical detection methods

Li Zhiyong, 36, came to the vascular Biomechanics Laboratory of the University of Cambridge to do research after finishing his doctorate in biomedical engineering at the University of London. No. 3 slag Portland cement, pozzolanic Portland cement and fly ash Portland cement have been the director of the laboratory since then, mainly engaged in research in the field of vascular biomechanics. He was awarded the title of "Britain's top young scientist and engineer" by the British House of Representatives. Even with such achievements, Li Zhiyong decided to return home. He said: "My relatives and most of my friends are in China. They feel at home only after returning home. In the past two years, the domestic research and development, innovation and entrepreneurship platform has also become better and better. Apart from these, I think China needs me. The morbidity, mortality and disability rates of cardiovascular and cerebrovascular diseases in China are very high, accounting for one fifth of the deaths of similar diseases in the world. In particular, stroke, the mortality rate in China is the first, which is very severe. I want to apply what I have learned over the years Serve the people and the motherland. " At the end of 2009, Li Zhiyong returned to teach at the school of Bioscience and medical engineering of Southeast University. His wife and children also came to Nanjing to live together

after returning home, Li Zhiyong has been teaching and doing research at Dongda, mainly studying the risk assessment and early warning system of stroke and myocardial infarction. Li Zhiyong, who has been devoted to learning, did not want to run his own company before returning home. He told that in foreign countries, the relationship between industry, University and research is very close, and the forms of cooperation are also diverse. I hope our research and development can play a role as soon as possible, so I have a plan to set up a company. In August last year, Li Zhiyong and the technical team established Nanjing jiantuo Biotechnology Co., Ltd. in Jiangning Economic and Technological Development Zone. At present, the company has 8 core technicians, all from the clinical medical school of Cambridge University, and has the world's leading core technology of vascular and blood flow imaging

lizhiyong told that cardiovascular and cerebrovascular diseases, such as myocardial infarction and stroke, which are difficult to maintain their current position if the fixture is replaced, are mostly atherosclerotic diseases caused by plaque rupture. This plaque is invisible and untouchable, and it is a major "killer" hidden in human blood vessels. Although the formation of plaque is a very slow process, and patients often have no obvious symptoms, secondary lesions caused by plaque, such as myocardial infarction, often occur suddenly, and sometimes even take people's lives within a few minutes, which makes people caught off guard, The current clinical testing instruments and equipment at home and abroad are also difficult to clearly detect the risk of plaque. The "vulnerable plaque evaluation system" developed by Li Zhiyong and his team is based on the principles of vascular imaging technology and blood flow dynamics to find vulnerable plaques before plaque rupture, especially the tortuous stress corrosion testing machine of blood vessels, which can carry out tortuous experiments on large-scale samples and prototype samples to the extent of occlusion, deformity and stenosis, and make timely judgments on whether treatment is needed, It is suggested that the severity should be treated with medication or surgery in time

at present, the technical service of the "vulnerable plaque evaluation system" has been put on clinical trial in Addenbrooke Hospital of Cambridge University, and the series of products are also in the final stage of integration, which is expected to be available in China within two years. Li Zhiyong also plans to cooperate with some domestic physical examination centers in the near future to carry out a large number of patient tests, obtain basic data, and further improve the system; Free testing points are set up in hospitals to provide free testing services for middle-aged and elderly people, hoping that the products can be recognized by the masses
