Clinical trial, an important research method, plays a crucial role in the development of medicine. It provides important decision support for medical workers. Medical research proposal should be posted at clinical trial registries. Researchers should update original data and research results, which contributes to data sharing. Clinical trial registration can avoid repetitive research and make clinical trials more transparent and standardized. This paper briefly introduces the clinical trial registration, including the definition, the significance, the history, the scope of registration, the organization of registration, and some common problems in the process of registration. Taking the application of clinical trial registration in the field of neurological research as an example, the article describes the current application status of clinical trial registration and explores it’s value and deficiency in specific clinical research, to provoke the awareness on trial registration, which can help to improve the quality of clinical trials.
Objective To summarize the methods and experience of animal experiment ethics training at home and abroad, analyze the opportunities and problems, and explore the ethics training methods suitable for the current situation of animal experiments in China. Methods Documents relating to animal experiment ethics training from January 2012 to February 2022 were searched in PubMed, Embase, China National Knowledge Infrastructure and Wanfang Data databases. After literature screening and data extraction by 2 researchers independently, descriptive analysis was performed. Results A total of 44 documents were selected, including 19 in Chinese and 25 in English, involving 44 institutions. According to the literature analysis, in the United States, Britain and other developed countries, the welfare and ethical laws for laboratory animals were relatively perfect, such as the Animal Welfare Act of the United States, the Animals (Scientific Procedures) Act of Britain, the Animal Welfare Act of German, and the Act on Welfare and Management of Animals of Japan, while in China administrative regulations were the main ones, and most of the institutions were restricted by management regulations; the ethics of personnel involved in animal experiments were uneven; the training time of some domestic institutions was less than that of institutions abroad; domestic training methods and contents needed to be improved. Basing on the comparative results at home and abroad and combining the training experience, West China Hospital of Sichuan University improved the animal experiment ethics training system. Conclusion It is suggested that the animal experimental institutions in China should improve the training methods, to enhance the awareness and cognition of people involved in animal experiments more systematically and scientifically, and strengthen the ethical review.
In the new era of development, countries in the world have realized the importance of cultivating interdisciplinary and innovative talents, and China is also paying more and more attention to the cultivation of medicine-engineering talents. Compared with the cultivation of single discipline postgraduates, the cultivation of medicine-engineering postgraduates involves effective integration of multiple disciplines, and its cultivation difficulty is greater. At present, China is still in the exploration stage of the medicine-engineering postgraduates training model. Therefore, this article intends to summarize the relatively mature and advanced medicine-engineering postgraduates training models at home and abroad, and extract experiences that are in line with China’s actual development, providing some suggestions for the establishment of postgraduates training systems of medicine-engineering interdisciplinary in China.
