In recent years, emerging technology medical devices have developed rapidly. How to more scientifically and more efficiently regulate these novel medical devices so as to improve access to advanced medical technology while ensuring safety and effectiveness is a new challenge faced by regulatory authorities, and is also the core topic of regulatory science. New tools, new standards and new methods are important means to achieve regulatory science. "Medical Device Development Tool" proposed by the U.S. FDA is a novel medical device regulatory science tool, which can help medical device developers to predict and evaluate product performance more efficiently. It is also helpful for regulatory authorities to make regulatory decisions more efficiently. This study introduces the concept, qualification process, role of MDDT in medical device regulation and MDDT examples, and makes some discussion on the device evaluation from the perspective of reliability and validity. MDDT can facilitate the developing of novel medical device.

3.Thoughts and suggestions on registration and classification of traditional Chinese medicines.
China Journal of Chinese Materia Medica 2020;45(16):4004-4008
In this paper, we reviewed the history of the registration and classification changes of traditional Chinese medicines(TCM) since the establishment of China's drug regulatory agency, and put forward relevant suggestions. Although China's drug regulatory agency has gone through 22 years, the whole regulatory system was gradually built on the basis of the generic pharmaceutical industry at that time and through continuous exploration and summary of simply experience from foreign regulatory agencies. To a certain extent, the supervision of TCM drugs was also affected by some immature supervision ideas during this period. Based on the newly issued Drug Administration Law and Provisions for Drug Registration, the author puts forward some personal thoughts on the classifications of TCM drug registration. It is hoped that experts in the industry and regulatory agencies will work together to explore and improve the relevant system of TCM registration administration.

Chinese patent orthopedic medicines feature complex components, mainly including desperate and toxic herbal pieces, narrow safety window, more clinical contraindications and frequent adverse drug reaction/events (ADR/ADE). To study the general safe medication regularity of Chinese patent orthopedic medicines, define key points in the medication education and ensure rational clinical medication, the authors took 80 types of commonly used Chinese patent orthopedic medicines as the study objects, collect 237 cases from 164 ADR/ADE documents through a system retrieval strategy, make a multidimensional literature analysis to determine the common risk factors for safe and rational medication of Chinese patent orthopedic medicines and establish an ADR/ADE prevention regularity. First, in the aspect of clinical symptoms, skin allergy is the most common ADR/ADE and closely related to the toxic ingredients, particularly accumulated liver or kidney damage caused by some drugs. Second, there are three time nodes in the ADR/ADE occurrence; The ADR/ADE occurred in 30 minutes is closely related to the idiosyncrasy; the ADR/ADE occurred between several months and half a year is related to the drug-induced liver and kidney damages; The most common ADR/ADE was observed within 7 days and predictable according to the pharmacological actions; Third, toxicity is an important factor in the occurrence of ADR/ADE of Chinese patent orthopedic medicines. Fourth, emphasis shall be given to the special medication factors, such as the combination with western medicines and Chinese herbal decoctions, overdose and long-course medication and self-medical therapy. In conclusion, the general ADR/ADE prevention regularity for Chinese patent orthopedic medicines was summarized to provide supports for clinicians in safe and rational medication and give the guidance for pharmacist in medication education.

The safety of Chinese patent medicine has become a focus of social. It is necessary to carry out work on post-marketing clinical safety evaluation for Chinese patent medicine. However, there have no criterions to guide the related research, it is urgent to set up a model and method to guide the practice for related research. According to a series of clinical research, we put forward some views, which contained clear and definite the objective and content of clinical safety evaluation, the work flow should be determined, make a list of items for safety evaluation project, and put forward the three level classification of risk control. We set up a model of post-marketing clinical safety evaluation for Chinese patent medicine. Based this model, the list of items can be used for ranking medicine risks, and then take steps for different risks, aims to lower the app:ds:risksrisk level. At last, the medicine can be managed by five steps in sequence. The five steps are, collect risk signal, risk recognition, risk assessment, risk management, and aftereffect assessment. We hope to provide new ideas for the future research.

According to the existing Provisions for Drug Registration (SFDA Order No. 28), applications for new drugs of traditional Chinese medicine are divided into two parts: the applications for drug clinical trial and for drug production (including new drug certificate). It will last for about 10 years from the application for drug clinical trial to get approving, and it also remains many problems and the low probability to succeed. From the sight of pharmaceutical review, there are mainly two aspects of regulatory compliance and technical issues, mainly for changes without approval of the competent authorities of the country. For example, sample preparation and approval of clinical trial process are significant changes. Technical problems are reporting incomplete data or information submitted does not comply with the technical requirements for review, such as: production process validation does not provide information, the preparation of samples for clinical trials and field inspection, production information, or the information provided does not meet the technical requirements. This paper summarizes the frequently asked questions and to make recommendations to advise applicants concerned, timely detection of problems, avoid risk, improving the quality and efficiency of the application for registration.
