In order to judge the future development trend of science and technology, plan ahead and lay out the frontier technology fields and directions, China Association of Chinese Medicine(CACM) has launched consultation projects for collecting "major scienti-fic issues and engineering technology difficulties in traditional Chinese medicine(TCM)" for the industry for three consecutive years since 2019. Up to now, 18 projects have been selected as major issues for research, and some experience and achievements have been made. These projects have been applied in important scientific and technological work such as scientific and technological planning and deployment at all levels of national, local, and scientific research institutions, the selection and cultivation of major national scientific and technological projects, and the construction of innovation bases, giving full play to the role of the think tank advisory committee of CACM. This study reviewed the selection of major issues for the first time, systematically combed its application in the national layout of science and technology, and put forward the existing problems and improvement suggestions, aiming to provide new ideas for further improving the selection of major issues and research direction, providing a theoretical basis and decision support for the national scientific and technological layout in the field of TCM, and promoting scientific and technological innovation to facilitate the high quality development of TCM.

Objective:<italic>Auxiliary Verse on Drugs and</italic> <italic>methods</italic> <italic>for Zang-Fu Organs （Fuxingjue Wuzangyongyao Fayao）</italic> written by TAO Hong-jing from the Liang dynasty covered many contents from<italic> </italic>a missing prescription book<italic> Classic of Decoction （Tangye Jingfa）</italic>， including a map revealing the compatibility principle of Chinese herbs， namely the Tangye Jingfatu. Represented by a centrosymmetric pentagon， the map describes a unique theoretical system for deficiency-excess syndrome differentiation of five Zang organs （liver， heart， spleen， lung and kidney） and the tonification-purgation and compatibility theory of five flavors （pungent， salt， sweet， sour and bitter）. Each Zang organ fixedly corresponds to one "property" flavor （purgation）， one "function" flavor （tonification） and one "transformation" flavor （harmonization） resulting from the combination of the former two. For example， the liver can be purged by sour， tonified by pungent， and moderated by sweet transformed by the combination of sour with pungent. The heart can be purged by bitter， tonified by salt， and astringed by sour transformed by the combination of bitter with salt. The spleen can be purged by pungent， tonified by sweet， and dried by bitter transformed by the interaction between pungent and sweet. The lung can be purged by salt， tonified by sour， and dispersed by pungent transformed by the combination of salt with sour. The kidney can be purged by sweet， tonified by bitter， and moistened by salt transformed by the combination of sweet with bitter. This study selected appropriate mathematical tools to analyze the fixed relationship between "property" flavor， "function" flavor and "transformation" flavor among the five Zang organs in “Tangye Jingfatu” and establish a mathematical model revealing the compatibility-transformation relationship among five flavors. Method:Based on the group representation of five elements （wood， fire， earth， metal， and water）， the correlations of "property" flavor， "function" flavor， and "transformation" flavor with five elements’ generation-restriction were deduced based on matrix calculation and group theory. The three-dimensional calculation method for vector product was expanded for establishing the mathematical operator of five flavors' compatibility-transformation. Result:<bold>and</bold> Conclusion:There is a mapping relationship of the purging， tonifying， and harmonizing functions represented by the "property" flavor， "function" flavor， and "transformation" flavor of the five zang organs in the "Tangye Jingfatu" with the five elements' generation-restriction. The established mathematical operator contributes to explaining the fixed collocations of five flavor transformation. Based on such algorithm， the tonifying and purging characteristics of five flavors in 10 representative classic prescriptions have been clearly expounded.

Objective::To observe the intervention effect of Yiqi Huoxue recipe (YQHX) on ventricular remodeling in rats with chronic heart failure, in order to explore its mechanism. Method::Among 40 male SD rats, 10 were randomly selected as the sham operation group. The left anterior descending coronary artery ligation was performed to construct the chronic heart failure(CHF) rat model. After modeling, they were randomly divided into model group, captopril group(13.5 mg·kg-1·d-1) and YQHX group (20 g·kg-1·d-1), and orally given the corresponding drugs. After 8 weeks of intervention, cardiac tissues were collected, body mass and heart mass were weighed, and echocardiography were performed to detect the changes in cardiac structure. Masson staining was performed to determine the myocardial interstitial collagen volume fraction. Western blot was used to detect the expression levels of mitochondrial fusion protein optic atrophy 1 (Opa1) and cleavage protein dynamic-related protein 1 (Drpl). The quantitative real-time fluorescence polymerase chain reaction(Real-time PCR)was applied to detect the expressions of Wnt/β-catenin pathway-related factors such as lipoprotein receptor-related protein 6 (LRP6), glycogen synthase kinase-3β (GSK-3β) and β-catenin. Result::Compared with the sham group, the left ventricular wall of the model group was significantly thickened (P<0.05), the cardiac cavity was significantly enlarged, and the content of collagen in the myocardial interstitium was increased (P<0.01). The expression level of Opal decreased, the expression level of Drp1 increased (P<0.05), the mRNA expression level of LRP6, GSK-3, and β-catenin increased (P<0.01). Compared with the model group, YQHX group can reduce ventricular wall thickening, heart chamber enlargement, myocardial interstitial collagen content, up-regulate the low expression of Opa1, but down-regulate the high expressions of Drpl, LRP6, GSK-3β, β-catenin(P<0.05, P<0.01). Conclusion::YQHX can effectively alleviate ventricular remodeling and improve mitochondrial energy metabolism in rats with CHF. The mechanism may be related to the inhibition of Wnt/β-catenin related factors.

Angiogenesis involves the occurrence and development of serious diseases such as cardiovascular and cerebrovascular diseases and malignant tumors. Promoting or inhibiting angiogenesis is considered to be a key factor in controlling the progression of the disease. Chinese materia medica (CMM) has become a research hotspot because of its good clinical therapeutic effect and significant intervention on angiogenesis. The zebrafish model as an ideal animal model also provides a good experimental basis for the study of angiogenesis. CMM monomers, extracts, prescriptions and Chinese patent medicine, and other forms of intervention were selected as the research object. Based on zebrafish animal model experiments, we summarize domestic and foreign relevant research and review the research progress of the effect of CMM on angiogenesis in zebrafish, aiming to provide reference for further development and application of zebrafish as a model and further study of CMM intervention in angiogenesis.
