If someone says that Hawking can stand up with just a few injections, people will most likely be suspicious. Hawking may shake his head: this is impossible. When magical stem cells appear in front of ordinary patients, rational judgment will soon lose their defense in the "flashing hope".
Scientists are still exploring the safety and effectiveness of stem cell therapy. However, under the advice of some "experts", patients eager to treat the disease also want to enjoy this "future technology" in advance. As a result, omnipotent stem cells rushed into the hospital bed, and danger and chaos came one after another.
At the 48th Academician Salon held yesterday, Shen Mingxian, a researcher of the Shanghai Academy of Social Sciences and director of the National Human Genome South Research Center ’s ethics department, revealed that China ’s first "ethical code for stem cell research and application" has entered the approval process of the Ministry of Health. Will be officially introduced.
Stem cell therapy caught in "gray zone"
In the fields of nerve damage and organ repair, universal stem cells have high hopes. China has always been encouraging the research on stem cells. At present, all trials are limited to the scope of research. So far, no pass has been issued for the clinical application of stem cell therapy other than hematopoietic stem cells.
When the patient is in a hurry, the "miracle stem cell therapy" continues to attract patients to start the "white mouse" willingly. "Right now, the so-called 'stem cell therapy' carried out by some institutions is in a 'gray zone' of science and non-science, norms and irregularities." Entrusted by the Ministry of Health, Shen Mingxian and a group of well-known ethicists from 2009 to 2010 Investigate the current status of stem cell therapy in China.
The chaotic status quo really caused experts to pinch the sweat: some people under the banner of stem cell treatment, bragging about the hype, claiming that "stem cells are cells that do everything", even exaggerating the efficacy, attracting with data such as 90% efficiency Patients; some institutions do not conduct research, or use research as the name, and apply technologies that have not been reviewed by scientists and ethical review in a hurry to the clinic and charge high fees.
"Crazy stem cells" have attracted the attention of foreign media. "Nature" and "Economist" magazines have successively commented on this. "Nature · Biotechnology" refers to this phenomenon as "Chinese Stem Cell Syndrome".
Strictly distinguish the research and application of new technologies
For cutting-edge biotechnology, it is difficult for ordinary patients to judge the authenticity and assess the risks. The management of relevant departments and the necessary regulations can protect the rights and interests of patients.
Shen Mingxian revealed that the forthcoming "Ethical Standards for Stem Cell Research and Application" will continue to support the research and application of stem cells, with the premise of strictly distinguishing preclinical research, clinical trials, and clinical applications. That is to say, from preclinical research to clinical trials belong to the category of research, and patients should not be charged; clinical application must be subject to administrative approval by relevant departments.
In fact, it is not the first time for patients to pursue “new technologyâ€. From "cranium detoxification" to "artificial heart implantation" to the "Shaw's reflex arc surgery" that was fired up a while ago, the various injuries caused by "new technology" to patients are, to a certain extent, all It is due to the haste on the road from research to application.
Shen Mingxian believes that a strict distinction between research and application is of universal significance for the standardized development of new medical technologies. "Shore's Reflected Arc technology has found a new way. From the perspective of scientific exploration, it may be a valuable research direction. Due to the lack of necessary specifications, it eventually ruined its future."
The rise of translational medicine highlights the importance of ethics
Compared with the "prudent promotion" attitude held by ethicists, advocating "translational medicine" from "lab to bed" is precisely to bridge the gap in the application of new technologies. As a virtuous circle with no end point, translational medicine is a continuous, two-way, open research process, which means that it will face the development of "stem cells" more directly and frequently.
"If you compare ethics to a bridge, with this bridge, it will be much smoother from research to clinical; without this bridge, research may not reach clinical, or you will have to go wrong, or even go astray." Shen Mingxian said The rise of translational medicine highlights the indispensability of ethics, making medical ethics research an unavoidable problem for every researcher and clinician.
In March 2009, as soon as he took office, Obama "slackened" stem cell research in the United States; previously, the US FDA (Food and Drug Administration) approved a stem cell clinical trial. Shen Mingxian regards this series of actions as a successful "rush run" planned by the US government-all trials and research are public, and whoever does what, what, and how much time is used is announced by the FDA; this is not only a powerful push The transformation of stem cell research into clinical practice has also paved the way for occupying a possible market in the future. It is undeniable that ethics has played a considerable role in it.
