[Textual research principles and suggestions on function and indication of ancient classical formulas].
Indication and functions is an important key information in the research and development of the ancient classical formulas, which directly affects the clinical positioning of the compound formulas and their reasonable, effective and safe use after marke-ting. It is also the embodiment of the ultimate vitality of ancient classical formulas. ⋯ Based on the analysis of the provenances, classification of clinical indications, and functions of 100 prescriptions in the Catalogue of Ancient Classical Formulas(First Batch), this paper summarized the incompleteness, irregularity and inconsistency in the original text, the differences in terminology between ancient and modern times, and the evolution of the meanings of prescriptions in different dynasties. In addition, under the guidance of the general principle of textual researh on ancient classical formulas, which is to inherit the essence, make the past serve the present, link up the past and the present, and bulid consensus, this paper proposed the following ideas: respecting the original meanings and provenances of ancient classical formulas, taking full consideration of the development and evolution, serving the current clinical application and health needs, accurately linking up the ancient and modern terminologies, standardizing the expression of traditional Chinese medicine(TCM) terminology, highlighting the characteristics of TCM, attaching importance to the textual research principles and suggestions of post-marketing evidence-based and clinical positioning research, so as to determine the the functions and indications of the ancient classical formulas in a scientific, standardized and reasonable way and better guide the clinical application of the classical formulas.

[Critical quality attribute assessment of big brand traditional Chinese medicine: process quality control method of Suhuang Zhike Capsules intermediate based on physical properties of powder and granules].
The physical properties of powder and granules are the critical quality attributes for the process control of Suhuang Zhike Capsules, a big brand traditional Chinese medicine. This paper took the production of 25 batches of real-world Suhuang Zhike Capsules dry extract powder and granules intermediates as the research object. Firstly, a method for testing the physical properties of Suhuang Zhike Capsules powder and granules with 19 physical indicators was established. ⋯ The results showed that the physical fingerprint similarity of 25 batches of dry extract powder was 0.639-0.976, and the physical fingerprint similarity of the gra-nules was 0.716-0.983. With the similarity of 0.85 as the threshold, the batches with abnormal physical properties could be identified. In this study, the process quality control method of Suhuang Zhike Capsules based on the physical properties of powder and granules was established finally, which realized the identification of abnormal batches, and provided a reference for the process quality control of Suhuang Zhike Capsules.

[Theoretical thinking on guiding research and development of new drugs of traditional Chinese medicine].
This article proposes that the research and development of new Chinese medicines should be based on the clinical values of traditional Chinese medicine(TCM), and expounds the multiple clinical values of new Chinese medicines such as therapeutic effects, adjuvant treatment effects, improvement of disease symptoms, improvement of quality of life, prevention of diseases, etc., so as to broaden the clinical indications of new Chinese medicines. It is pointed out that the clinical value of TCM determines the clinical efficacy evaluation method of new Chinese medicines, so as to construct a clinical evaluation system of new Chinese medicines with the characteristics of TCM. It is proposed that the clinical value of new Chinese medicines should be found under the guidance of TCM theo-ry and clinical practice, and the theoretical innovation of TCM should be emphasized. ⋯ In view of the characteristics of new Chinese medicine research and development, it is proposed that the supporting role of human experience should be emphasized, and the technical points of clinical trials of new syndrome-type Chinese medicines should be explained. The use of objective indicators for syndrome evaluation, the selection of appropriate scales, and the formulation of reasonable treatment courses are advocated. During the research and development of new Chinese medicines, it is not only necessary to pay attention to modern medical safety indicators, but also to observe the evolution of TCM syndromes and specific TCM symptoms.

[Application of add-on-design in post-marketing evaluation of traditional Chinese medicine].
Post-marketing evaluation of traditional Chinese medicine(TCM) is an important research stage in the life cycle of a drug, and the add-on-design is a common method for its post-marketing evaluation. This article introduces the basic concept of add-on-design, and points out that it is suitable for use based on the principles of medical ethics when the standard treatment should not be interrupted. The post-marketing evaluation of TCM should be carried out based on human experience and in compliance with regulations and ethics. ⋯ Besides, the research conclusions are easily put into clinical application. But there are also many difficulties, such as the influence of confounding bias, the "ceiling" effect of clinical efficacy, and the difficulty of interpretation of adverse events. Therefore, a rigorous research quality assu-rance system should be established, and the quality control of evaluation consistency of researchers should be emphasized to ensure strict quality control in the research process.

Meta Analysis[Pharmacoeconomic evaluation of Shexiang Tongxin Dropping Pills combined with conventional Western medicine treatment for coronary heart disease by Markov model].
This research was to evaluate the economics of Shexiang Tongxin Dropping Pills combined with conventional therapy for patients with coronary heart disease(CHD) in Chinese medical environment. From the perspective of medical insurance, a Markov model was established in this study based on the results of Meta-analysis comparing the effectiveness and safety of Shexiang Tongxin Dripping Pills combined with conventional treatment and conventional treatment alone. The experimental group was treated with She-xiang Tongxin Dropping Pills combined with conventional Western medicine treatment, while the control group was treated with conventional Western medicine treatment alone. ⋯ Compared with the conventional treatment alone, the Shexiang Tongxin Dropping Pills combined with conventional treatment had lower long-term cost and higher health output, with advantages of cost-utility and pharmacoeconomic advantages. The sensitivity analysis results showed that the conclusion was relatively stable. Based on the above results, it is considered that compared with the conventional Western medicine alone, Shexiang Tongxin Dropping Pill combined with conventional Western medicine is a treatment regimen with pharmacoeconomic advantages for the treatment of CHD.
