ABSTRACT
OBJECTIVE To compare and study the supporting policies for the filing man agement system of traditional Chinese medicine preparation prepared by traditional technology （hereinafter referred to as “TCM preparation ”）in medical institutions issued by the state and various provinces ，and their development ，so as to provide reference for the improvement of the follow-up supervision and management of the filing works. METHODS According to Announcement on the Filing Management of TCM Preparations Prepared by Medical Institutions Using Traditional Processes issued by former National Food and Drug Administration （hereinafter referred to as the Announcement）as well as notices and specific implementation rules issued by provincial bureaus ，the filing work data of 10 provinces in recent 3 years were selected for comparison ，sorting，statistics，classification and induction. The policy characteristics and progress of filing work were studied. RESULTS & CONCLUSIONS According to the local actual situation，some provinces had refined or expanded the contents of several parts of the Announcement，such as the scope of TCM preparations，the situation not allowed to record ，the filing process and working time requirements ，the disclosure ，change and cancellation of filing information ，and the implementation of supervision and management. The statistical results of filing data in 10 provinces showed that compared with 2019，the number of TCM preparation declared for filing and medical institutions declared for filing had increased with growth rate of 91.0％ and 48.8％ respectively in 2020. There is still room for improvement in the supporting policies for the filing of TCM preparations ，which can be optimized by referring to the features of some provinces ’ implementation policies ，refining the construction of norms and standards ，and strengthening the construction of regulatory system platform. It is necessary to optimize policy and strengthen the capacity building of reporting institutions in advance ；carry out daily supervision and control risk based on risk during the filing management ；emphasize follow-up supervision ，strengthen the construction of ADR monitoring system in medical institutions ，and carry out life cycle supervision and management constructively afterwards，in order to promote the further development of TCM preparations in medical institutions.

ABSTRACT
Chinese medicinals feature different medicinal parts and enriched components, which makes their powders show obvious microscopic identification characteristics and specific physical properties. On this basis, the commonly used Chinese medicinals can be divided into several categories, such as powdery, fibrous, sugar, oil, and brittle materials, which is of great importance to the research and development of personalized Chinese medicinal preparation technology. However, the existing classification methods are highly subjective and thus difficult to meet the requirements for the development of personalized Chinese medicinal preparations with high quality. In this study, 55 representative Chinese medicinals, such as Dioscoreae Rhizoma and Leonuri Herba, were selected, and the physical properties of their powders were systematically characterized by comprehensive powder tester, torque rheometer, texture analyzer, etc., based on which a data set encompassing physical properties of these powders was built. The typical physical fingerprints of powders from the above 5 categories were established by multivariate statistical analysis. Then, the Chinese medicinals were classified according to the Euclidean distance between each of them and the typical value in the PCA score plot. For those with multiple material properties, whose classification boundary was fuzzy, the proportions of different types of materials were calculated with the combination of Euclidean distance, powder properties, microscopic identification characteristics, and chemical composition, so as to achieve the multivariate quantitative classification of Chinese medicinals. This lays the foundation for the further creation of intelligent personalized Chinese medicinal preparation technology.

ABSTRACT
Excavating and characterizing the dosage forms characteristics of classic Chinese medicine preparations is the basis for the innovation of modern preparations of Chinese medicine. Through the combing statistics of the National Natural Science Foundation of China (NSFC) on the establishment of traditional Chinese medicine preparations, the research literature on Chinese medicine preparations at home and abroad, and the registration of new Chinese medicines in the past ten years, this paper finds that the research projects of classic Chinese medicines have been greatly reduced. The market share of traditional Chinese medicine classics has shrunk year by year. The modern preparation produced in the "preparation of traditional Chinese medicine by western medicine technology" mode dominates the market. However, because of its "degraded" effect, it is less competitive. Therefore, with the wave of classic dosage forms research promoted by national policies, accelerating the study of classical Chinese medicine preparations will not only promote the development of pharmaceutical discipline of traditional Chinese medicine, enhance the classic medical culture literacy, but also promote the protection and inheritance of classic medicine.
