Professor Chuan University 3D printed blood vessels, 30 test monkeys lived well
Release date: 2016-12-14 3D bioprinted blood vessels for implant replacement. Professor Kang Yujian's research has created a new era of vascular disease treatment. An amazing data More than 1.7 billion people with cardiovascular and cerebrovascular diseases worldwide, accounting for a quarter of the world's population a successful experiment To solve the problem of endothelialization of artificial blood vessels, at least 100 million people need such technology every year. a major breakthrough Successful cases of scientific and technological achievements will be applied to the human body in the next three to five years. a lifetime of accumulation Professor Kang Yujian has been accumulating for at least 20 years, and the time invested cannot be measured in terms of length. On December 11th, the experiment of 3D bioprinting blood vessel implantation into rhesus monkeys was successful and caused a sensation. Some analysts believe that this marks a successful solution to the problem of endothelialization of artificial blood vessels that has plagued the clinical half-century, and has brought good news to more than 1.7 billion cardiovascular patients worldwide. At 8:40 pm on the evening of the 12th, Huaxi Dushi Bao reporter saw the head of the monkey experiment in a hotel lobby in Chengdu, Professor of Reproductive Medicine Research Center of West China Hospital of Sichuan University, and Kang Yujian, CEO and chief scientist of Blu-ray Inno. At that time, he was discussing the problems of the big health industry with two experts from Beijing and Chengdu. Nearly sixty years old, his face could not help but show a trace of fatigue, and occasionally he took off his glasses and licked his face. "I am going to Kunming on the 13th. There is a big health industry forum on the 14th. I want to make a report on the forum." Kang Yujian is very busy. On his face, I don't see much success. Some are just one. The rigor and perseverance of a scientist. Experimental significance "Initiated a new era in the treatment of vascular diseases" As of December 1, 2016, 30 rhesus monkeys have been subjected to 3D bioprinting in vivo implantation experiments, and the survival rate of experimental animals was 100%. Kang Yujian has only three simple evaluations of his research results. "The success of this experiment has created a new era in the treatment of vascular diseases." Kang Yujian said that artificial blood vessels have been appearing for more than half a century, but the problem of re-clogging of artificial blood vessels has not been solved. "3D bioprinting blood vessels completely solve the problem of endothelialization of artificial blood vessels, and there is no reocclusion." Kang Yujian said that the second meaning of the experiment is that "the new era of 3D bioprinting in medical applications has been opened up." Kang Yujian said that the significance of the experimental results is also to create a new direction in the field of stem cells. According to the World Health Organization, the number of patients with cardiovascular and cerebrovascular diseases in 2012 has exceeded 1.7 billion, accounting for a quarter of the global population. "Now from a global perspective, at least 100 million people need such technology every year." Kang Yujian told reporters that it will be applied to the human body in the next three to five years. Face up to question "The only metric is useful and useless." Kang Yujian’s good friend, also a mechanical engineering expert returning from overseas study, and Xia Yingqi, secretary general of Beijing Zhongguancun Forum Association, bluntly said that he is a questioning faction. "I was happy when I first started to hear about it," Xia Yingqi said at the beginning. "It is almost impossible." Although he is a well-known industry expert and professor, Xia Yingqi still calls Kang Yu as "Kang Kang". “When Dr. Kang returned to China in 2009, we met in 2010 and kept in touch.†Xia Yingqi said that he has been paying attention to the results of each stage of 3D bio-printing blood vessels, and he has also changed from questioning to ambiguity. "In the field of life sciences and 3D bio-printing, there are many people studying, but there are no obvious results." The research results obtained by Kang Yujian, in Xia Yingqi's view, "is a very great thing, the future is limitless." In fact, the questioning of Kang Yujian is far more than that. “After 3D printing was applied in the medical field, everyone was questioning, thinking that this is a gimmick, how useful can it be?†Kang Yujian said that he never cares about being questioned. “I’m not sure if I’m doing this. The only measure that is useful is useless." Transformation research “Sichuan monkeys and young people left me here†Before returning to China, Kang Yujian was already a full professor at the University of Louisville School of Medicine and director of the Center for Basic Research in Gastrointestinal and Liver Diseases. In 2009, Kang Yujian returned to China and started full-time work at the Center for Regenerative Medicine of West China Hospital of Sichuan University. When it comes to choosing to stay in Chengdu, Kang Yujian is attributed to the monkeys and young people here. "The research I have done has reached a stage. I used to experiment with mice in the United States, hoping to use people." Kang Yujian told reporters, but the experiment can not jump directly from the mouse to the human body, there must be Transition, "is a monkey." “Sichuan has a wealth of monkey resources. The best macaques in the world are in Sichuan, and only the Animal Experimental Center of Huaxi Hospital is the only unit that allows legal experiments with monkeys, which can satisfy my research on transformation,†he said. But this is only a factor of monkeys, not enough to let Kang Yujian stay in Sichuan. Another reason for Kang Yujian’s stay is the young people in Sichuan. “In this impetuous environment, the young people here can still do things in a down-to-earth manner. It is a great encouragement to me and it will take me. Stay in this place firmly." Kang Yujian once said that it is a pity that he did not live in Sichuan, but he has to find a cemetery in Sichuan to leave it to himself... Have one say one Jianyan Researcher “Accumulation is very important, don’t rush to publish an article†The success of 3D bioprinting blood vessels in rhesus monkeys is not only a major breakthrough in scientific research, but also a clinical application in the near future. This is undoubtedly a successful case of the transformation of scientific and technological achievements. But in fact, according to statistics released by the National Development and Reform Commission, China's scientific and technological achievements conversion rate is only 10%, far lower than 40% of developed countries. In this regard, Kang Yujian believes that the current management and evaluation mechanism of scientific research institutions in China is “not encouraging the transformation of scientific research resultsâ€. "For example, the 3D bioprinting blood vessel experiment is a very sensational thing in the outside world, but I have accumulated at least 20 years. During this period, I did not publish an article." Kang Yujian said. Kang Yujian told reporters that he was studying 3D bioprinting. "The time invested can't be measured in terms of length. This is my life's investment." In the eyes of Others, it is only a scientific research result, but for researchers, "is a very long process." "Now some young people come out of school, don't understand anything, don't have enough accumulation, just want to publish an article quickly, and think about it before they mature." Kang Yujian said, therefore, there are many people, "This life is published." A lot of articles, but Dongyi Shantou West has a stick. In the end, it is difficult to have the result of industrial transformation. Advise international students "Returning to your hometown, you must first have the ability to return." Kang Yujian, who went abroad to study in the late 1980s, is now the country's first batch of national special experts for the “Overseas High-level Talents Introduction Program†(Thousand Talents Program). His old friend Xia Yingqi said that after returning from this group of overseas students, "the emphasis is on achieving personal goals and value to society." In recent years, more and more young people have chosen to study abroad. Kang Yu has his own views on this phenomenon. "People who go abroad have always reported their feelings about the country. No matter where they are, they will never forget their hometown. This is human nature." Kang Yujian said. However, as to whether or not you can return to your hometown, it depends on two conditions. "First of all, I have to see if I have this ability. Otherwise, I will go out and come back. What should I return to my hometown?" Kang Yujian said that the second condition is to have the opportunity to return home. The so-called opportunity is to see what is needed in the hometown. "There is no channel in my hometown. I am going back to build a canal. This is an opportunity."
