Objective: To compare the pharmacodynamic action of Radix Notoginseng after fermented by different strains bioconversion.Methods:The models of cerebral ischemia and hypoxia were established,thrombosis in vivo were induced by collagen-Adr,ventricular fibrillation of mice by chloroform,and perfusion experiment of the ex vivo heart of cavia cobaya was used.Results:100,200mg/kg doses of all samples had protective effects on ischemia and hypoxia mice,1# sample can inhibit thrombosis induced by collagen-adrenaline obviously after intraperitoneal injection in dosage of 200mg?kg-1?d-1 for 5days.All groups significantly reduced the incidents of ventricullar fibrillation induced by chloroform in mice except 100mg/kg dose of 1#,furthermore,compared with control high dose group(5#),the incidents of high dose groups of 3、4# deceased significantly.All samples had the effect of dilating coronary artery,but there effects on myocardial contractile force and cardiac preload were different.Conclusion:The primary cardiovascular related pharmacological researches demonstrated the vary action changes of 1-4# samples compared with the sample 5#.This result has revealed that the chemical structure of Radix Notoginseng transformed and that is coincide with initial analysis of phytochemical analysis.

OBJECTIVE To clarify the core content of traditional Chinese medicine (TCM) policy in the provinces of China, so as to provide reference for optimizing the structure of the policy system of traditional Chinese medicine in China and assisting the inheritance and innovation of TCM industry in various regions. METHODS The websites of directly affiliated organs in 31 provinces, excluding Hong Kong, Macao and Taiwan, were retrieved to collect the TCM policies released from 2000 to 2021. The importance of keywords in the TCM policies of each province was measured based on term frequency-inverse documentation frequency (TF-IDF) keyword extraction method, and the similarities and differences were analyzed among TCM policies. RESULTS & CONCLUSIONS A total of 99 documents related to TCM policies of various provinces were obtained in this study, most of which were released after 2016. The theme of national TCM policy covered four aspects: building TCM talent team, perfecting TCM service system, strengthening TCM resource management and promoting TCM industry innovation. The TF-IDF values of “medical institutions”“traditional Chinese medicine”“medical treatment” were higher than other keywords in each province, indicating that the provinces paid more attention to the construction of TCM service system and the management of TCM resources than other aspects. Anhui and Jiangsu, Beijing and Henan, Hubei and Jilin, Hubei and Tianjin, and Hubei and Yunnan had the more degree of similarity in TCM policies, which all contained 16 of the same keywords. Therefore, the above regions should be encouraged to strengthen exchanges and cooperation and realize mutual promotion and joint development. Among all the keywords whose importance ratio was greater than 0.2,“ Tibetan medicine” was unique to Qinghai and Tibet,“ disease type” was unique to Guangdong, and the TF-IDF value of “supervision and management” in Beijing was higher, indicating that the emphasis of TCM policy formulation in different provinces was various. Meanwhile, the top 10 keywords of TF- IDF value in all provinces did not have words related to financial input, and the TF-IDF values of “informatization” in most provinces did not rank at the top. It is suggested to increase financial input or encourage social financing, and add “Internet+new business” in the field of TCM.
