Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

OBJECTIVE To investigate the improvement mechanism of hyperoside （HYP） on non-alcoholic fatty liver disease （NAFLD）. METHODS Male C57BL/6 mice were randomly divided into normal （NFD） group， model （HFD） group and HYP group， with 8 mice in each group. Except for NFD group， the mice in other groups were fed with HF60 high-fat diet to establish NAFLD model； HYP group was simultaneously given HYP 100 mg/kg intragastrically every day， for 16 consecutive weeks. The body weight and liver weight of mice in each group were recorded 16 h after the last medication； the histopathological changes and lipid accumulation in the liver were observed， and the contents of triglyceride （TAG） in liver tissue and serum contents of TAG， aspartate transaminase （AST） and alanine transaminase （ALT） were measured； LC-MS/MS method was adopted to detect lipid changes in the liver tissue of mice for lipidomics analysis， and protein expressions of lipid synthesis-associated proteins peroxisome proliferator-activated receptor α （PPARα） were also tested. Human hepatocellular carcinoma cell line HepG2 was divided into normal control group， model group， HYP low-concentration group （50 μmol/L）， HYP high-concentration group （100 μmol/L）， HYP low-concentration+GW6471 （PPARαinhibitor） group， and HYP high-concentration+GW6471 group. Except for normal control group， the remaining cells were induced with oleic acid and palmitic acid to establish a high-fat cell model. The accumulation of lipid droplets in each group of cells was observed， and the TAG content was detected. RESULTS Compared with HFD group， HYP group exhibited significant reductions in liver fat vacuoles， lipid accumulation， liver weight， and TAG content in liver tissue， as well as serum contents of ALT， AST and TAG （P＜0.05）. Additionally， the expression of PPARα protein in liver tissue was significantly increased （P＜0.05）， and the pathological morphological changes associated with NAFLD were alleviated. Lipidomic analysis revealed that HYP significantly reduced the levels of TAG， diacylglycerol and other lipids in the liver. Compared with model group， cellular lipid droplet accumulation and TAG content decreased significantly in HYP low- and high-concentration groups （P＜0.05）； GW6471 could significantly reverse the improvement effect of HYP on above indicators （P＜0.05）. CONCLUSIONS HYP can effectively ameliorate NAFLD induced by a high-fat diet in mice， and the mechanism may be related to the activation of PPARα to regulate hepatic lipid synthesis.

Objective:To construct a temperature-sensitive hydrogel (PF-CA@AS-IV hydrogel) composed of Pluronic F-127 (PF-127)/calcium alginate (CA) loaded with astragaloside IV (AS-IV), and to explore its repair effect and potential mechanism on diabetic skin ulcers (DSU).Methods:The PF-CA@AS-IV hydrogel loaded with AS-IV and gelling at 37 ℃ was prepared. Its temperature sensitivity, rheological properties, and morphology were characterized. A rat model of DSU was established, and the rats were randomly divided into blank control group, model group, AS-IV spray group, PF-CA hydrogel group, and PF-CA@AS-IV hydrogel group ( n=5 each). After 21 days of intervention, the wound healing rate of each group was evaluated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of granulation tissue, and immunohistochemistry was applied to detect the expression level of CD34, a marker of new blood vessels. Results:Rheological analysis showed that the storage modulus (G′) of PF-CA@AS-IV hydrogel began to exceed the loss modulus (G″) at 33 ℃, and a stable three-dimensional network structure was formed at 37 ℃. Scanning electron microscopy confirmed its loose and porous microstructure. Animal experiment results indicated that compared with the blank control group, the model group had a significantly lower wound healing rate, massive infiltration of inflammatory cells, and fewer new capillaries and CD34 expression (all P<0.05). Compared with the model group, each treatment group can promote wound healing, reduce inflammatory infiltration and increase the positive expression of CD34 to varying degrees (all P<0.05), and the curative effect of PF-CA@AS-IV hydrogel group is the most significant, which is better than that of AS-IV spray group and PF-CA hydrogel group (all P<0.05). Conclusions:PF-CA@AS-IV hydrogel can effectively regulate inflammatory response and promote angiogenesis through sustained release of AS-IV, thereby accelerating DSU healing, and has good translational potential in the field of chronic wound repair.
