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.

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.
