Clinical Application and Quality Analysis of Classical Formula Xiaoyaowan： A Review / 中国实验方剂学杂志

Xiaoyaowan has the effects of soothing the liver， invigorating the spleen， regulating menstruation， and nourishing blood. It is often used to treat the distending pain of the chest and hypochondriac， loss of appetite， dizziness， and irregular menstruation caused by liver depression and spleen deficiency. The formula originated from the Sinisan of Treatise on Cold Damage（《伤寒论》） in the Han dynasty and was officially formulated in the Song dynasty's Taiping Royal Prescriptions（《太平惠民合计局方》）. In the Ming and Qing dynasties， it was developed into more comprehensive formulas such as modified Bazhentang， modified Xiaoyaowan， and other formulas. In recent years， Xiaoyaowan has become a classic formula for treating many symptoms of liver depression. The Pharmacopoeia of the People's Republic of China（《中华人民共和国药典》）， 2020 edition， records Xiaoyaowan and modified Xiaoyaowan. Modern clinical research has further expanded the therapeutic range of this formula. Through literature research， it is found that there are certain reports on the clinical application and quality analysis of Xiaoyaowan， but the relevant literature lacks collation so far. Therefore， relevant literature was consulted and sorted out. The paper summarized the treatment of mammary hyperplasia， depression， irregular menstruation， melasma， menopausal syndrome， and polycystic ovary syndrome with Xiaoyaowan， as well as the quality analysis of paeoniflorin， ferulic acid， and glycyrrhizinic acid of Xiaoyaowan. It is expected to lay a foundation for further research on clinical application， pharmacodynamic mechanism， and quality control of this classic formula.

Research on Preparation Process and Quality Evaluation of Traditional Chinese Medicine Dispensing Granules and Its Consistency with Traditional Decoction： A Review / 中国实验方剂学杂志

Traditional Chinese medicine dispensing granules（TCMDGs）is the new type of decoction pieces with the development of modernization of TCM， which has received mixed opinions since its practical application. In 2021， the national departments issued Announcement on Ending the Pilot Work of TCMDGs， marking the end of the 28-year pilot work of TCMDGs， and eligible TCM enterprises can produce TCMDGs after filing. However， this does not mean that the preparation process， quality standard and efficacy research of TCMDGs have been developed and matured， on the contrary， there are still some problems that need to be solved and gradually improved. For example， in the production process， there are problems such as unclear， unified and non-standardized preparation parameters. In terms of quality control， there are some problems such as lack of producing area regulation， variety selection and processing specification. In terms of consistency evaluation with traditional decoction， there are problems such as unclear relationship between the chemical constituents and pharmacological effects of the two. Therefore， in view of some prominent problems of TCMDGs at present， this paper takes the published literature as the main data source and combines the specific requirements of the code or technical standards such as the 2020 edition of Chinese Pharmacopoeia， Publicity of the Unified Standard on the Varieties of TCMDGs， Quality Control and Standard Formulation Technical Requirements of TCMDGs. The production process of TCMDGs， the origin and variety of raw materials， the processing of decoction pieces， the quality control standard and the consistency evaluation of formula granules and traditional decoction were sorted out and visualized by literature mining， data analysis and list comparison. Based on the analysis results， the following suggestions were made. In terms of preparation process， the completeness and standardization of process parameters should be strengthened. In terms of quality evaluation， attention should be paid to the relationship between the authenticity， variety， processing and quality of medicinal materials. In the consistency evaluation of formula granules and traditional decoction， the deep difference and mechanism between TCMDGs and traditional decoction were discussed by combining structural Chinese medicine， quality marker（Q-Marker） theory and physicochemical characterization， so as to provide reference for the application and development of TCMDGs.
