[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.

[Application of objective performance criteria in post-marketing evaluation schemes of traditional Chinese medicine].
Traditional Chinese medicines(TCMs) have certain limitations in the clinical research design in their post-marketing evaluation, so that randomized controlled programs cannot be strictly implemented in some studies, while the objective performance criteria is a reasonable external controlled research method that has been gradually recognized at home and abroad in recent years in addition to randomized controlled trial(RCT) method. It is more mature in medical devices, surgery and other research fields, but there is no relevant report in the field of post-marketing evaluation of Chinese patent medicines. ⋯ However, in the application process, we should pay attention to the key issues such as the selection of index, research population, follow-up period and the reference selection, to ensure the quality of research. This research group has carried out some exploration and practice in the field of post-marketing evaluation of TCM injections by using single arm combined with the objective performance criteria, hoping to establish the key technology in this field, and provide certain research and design reference for the secondary development of Chinese patent medicines.

[Conception and practice of "three dimensions and four stages" clinical orientation method for post-marketing evaluation of traditional Chinese medicine].
The article summarized the relevant researches on the clinical orientation of Chinese patent medicines, and put forward the post-marking principle and strategies of the clinical orientation. The principle could be illustrated by four criteria: overall design, step-by-step implementation, from easiness to hardness, gradual concentration. The strategies were as follows: first carrying out the projects with little cost of money and time, and then the projects requiring much cost of money and time, so that the possibility of fai-lure would be put forward at an early stage to reduce the loss caused by research failure as much as possible by consolidating the research projects with less investment at the early stage and gradually increasing the research projects with more investment at the later stage. ⋯ Medicines, diseases and patients were the "three dimensions", so we should understand the features and interaction of the target indications, symptoms and population to establish a three-dimensional clinical positioning coordinate system. "Four stages" were the four steps of clues analyzing, hypothesis orientation, preliminary verification and clinical validation. Each latter stage should be started after full completion of the former one, and the latter stage results shall be used to validate and revise the former clinical orientational hypothesis, continuously forming a feedback circle. Based on the sufficient verification of previous study, prospective clinical trials were implemented at last to get the best evidence-based evidence of clinical orientational hypothesis.
