何首乌相关肝损伤研究进展

Research progress of liver injury induced by Polygoni Mulitiflori Radix

何首乌为蓼科植物何首乌Polygonum multiflorum的干燥块根,是一种传统的滋补中药,具有补肝肾、益精血以及乌发等作用,在临床和保健品中得到广泛使用。近年来,临床上有关何首乌及其制剂不良反应的报道日益增加,引起广泛关注。关于何首乌所致肝损伤的实验结果也不断增多,并且有实质性的研究进展。根据近十年有关何首乌肝损伤的临床报道,该文从使用方法、用药剂量以及使用时长等方面进行分析,发现何首乌生制不分,且长期大剂量服用是造成肝损伤的主要原因;此外,何首乌引起的肝损伤为特异质肝损伤,个体因素也是出现不良反应的重要原因。同时根据文献报道,整理了何首乌中的化学成分在不同病理动物模型中的作用,发现何首乌中的二苯乙烯苷是引起肝损伤的主要成分;结合何首乌引起肝损伤的临床表现,对有关机制如一些化学成分对胆红素和胆汁酸代谢的影响进行分析研究。该文就何首乌相关肝损伤研究进展进行综述。

Polygoni Mulitiflori Radix, or dried root tuber of Polygonum multiflorum(PM), is a traditional Chinese tonic medicine, with the effect in nourishing liver and kidney, and benefiting blood essence and hair. It is widely used in clinical and healthcare products. In recent years, more and more reports about adverse reactions of root tuber of P.multiflorum and its preparations have been reported. Fortunately, there is also substantial progress in the experimental study on liver injury induced by PM. According to the literature review, the possible causes of liver injury were found to be the mixture of raw and processed PM and long-term high-dose administration. In addition, the liver injury induced by PM is idiosyncratic liver injury, and individual factors are also the important cause. At the same time, according to the literature reports, the effects of chemical components in different pathological animal models were summarized, finding that 2,3,5,4′-tetrahydroxystilbene-2-O-β-D-glucoside was the main component for liver injury;based on the clinical manifestations of liver injury induced by PM, the effects of some chemical components on bilirubin and bile acid metabolism were analyzed. This paper reviews the study progress of liver injury induced by PM.
