Analysis of Pharmacovigilance Thoughts in Herbal Masterpieces of Ming Dynasty / 中国实验方剂学杂志

Based on the pharmacovigilance thoughts of Chinese medicine of cognition, application, prevention and rescue of drug toxicity, to sort out the pharmacovigilance information in representative herbal works of the Ming dynasty, and to analyze the characteristics of the pharmacovigilance thoughts of the Ming dynasty, so as to provide reference for rational drug use in modern clinical practice. Taking Bencao Pinhui Jingyao, Bencao Gangmu, Paozhi Dafa, Bencao Shengya Banjie, Bencao Mengquan as the blueprints, and taking the traditional Chinese medicines in these books as the research objects, the text information was extracted from the four aspects of drug identification, drug use, drug prevention and detoxification, and the idea of pharmacovigilance was summarized. In Ming dynasty, pharmacovigilance had a systematic understanding, and cognition of drug toxicity was clear in identifying poison and correcting the mistakes of predecessors, in the aspects of using and preventing poisons, the use of poisons was prominent, the compatibility and process of poisons were emphasized, and the methods and mechanism of poison relief were clear in detoxification. Ming dynasty has initially formed the whole pharmacovigilance theoretical frame of cognition, application, prevention and rescue of drug toxicity, which has certain guiding and reference significance for modern clinical rational drug use.

Research Status of Gouty Arthritis at Home and Abroad-Visual Analysis Based on CiteSpace Software / 中国实验方剂学杂志

Objective:To analyze the research status of gouty arthritis at home and abroad in the past 15 years，and to provide reference for for further in-depth research in this field. Method:With “Gouty arthritis” as the research topic, the related papers during 2004—2019 were searched in Web of science core collection database and CNKI databases respectively. The results were statistically sorted out according to publication year，author，institution，literature source and key words，etc，and were visualized by CiteSpace software. Result:A total of 5 071 Chinese papers and 1 136 English papers were included. The amount of domestic and foreign publications continued to rise，forming a core team represented by LI Zhao-fu，XIONG Hui，SCHLESINGER NAOMI and other authors. The research hotpots focused on the pathogenesis，diagnosis methods， Chinese and Western medicine treatment，clinical observation，risk assessment and other aspects of gouty arthritis. Both of them had their own emphases. Domestic researches tended to focus on the treatment of gouty arthritis with traditional Chinese medicine，while foreign ones focused on the pathological research and clinical investigation of gouty arthritis. Conclusion:The number of researches in the field of gouty arthritis is on the rise as a whole，and there are both consistency and differences in the research content and hot topics between domestic and foreign literature. Therefore， we should strengthen cooperation and exchange between different teams and countries，so as to promote the overall development of this field.

Toxicological research and safety consideration of coumarins / 中国中药杂志

Coumarin is an important class of natural organic compounds, which widely exists in a variety of plants and microorganisms. Coumarins have many biological activities and wide clinical applications, such as anti-tumor, anti-HIV, anti-bacterial, anti-inflammatory, anti-oxidation, anti-coagulation, but they have obvious toxic effects in rodents. It was found that the toxicity of coumarins in different animals and organs was significantly different, and high dose oral administration was more likely to produce toxic reactions. Based on the research and analysis of domestic and foreign literatures in recent 60 years, this paper mainly summarized the hepatotoxicity and pulmonary toxicity induced by coumarins, and probed into their possible mechanisms. It was found that the toxicity of coumarins had metabolic differences and species differences. The liver of rats and lungs of mice were more susceptible to coumarins. Toxic reactions occurred mainly in the second metabolic pathway of coumarin metabolism in vivo. In order to put forward safety considerations and evaluate the impact of coumarin on human body, it was found that coumarin is unlikely to produce hepatotoxicity at normal exposure level. It was also suggested that species differences due to different metabolic patterns in model animals should be carefully considered when assessing coumarin toxicity, in order to provide reference for clinical research and rational use of coumarins and improve the rational use of coumarins.
