Study on mechanism of Xixian Tongshuan Capsules based on network pharmacology / 中国中药杂志

ABSTRACT

Xixian Tongshuan Capsules with functions of promoting blood circulation and removing blood stasis,dispelling wind and resolving phlegm,relaxing muscles and activating collaterals,restoring consciousness and inducing resuscitation,has significant effects on main and concurrently symptoms of apoplexy. In this research,908 chemical compounds of Xixian Tongshuan Capsules were collected,and 337 potential targets were discovered by pharmacophore based reverse target identification. Protein interaction network( PIN)was then constructed and Identifying Protein Complex Algorithm( IPCA) was used to obtain the modules of the capsule and analyze the potential action mechanism. According to the research,Xixian Tongshuan Capsules could play a therapeutic role for hyperlipidemia and hypertension by regulating lipid metabolic process and blood pressure,the most direct risk factors of apoplexy. It could be used to treat the cerebral thrombosis and irreversible death of nerve tissue caused by insufficient supply of cerebral tissue blood and oxygen,in a way of regulating blood circulation system and nervous system. Xixian Tongshuan Capsules could also treat stroke-induced inflammation and inflammatory immune response through its regulatory effect on inflammatory immune response. Based on the network analysis,the antiinflammatory activity of Xixian Tongshuan Capsules extracts was investigated by measuring the NO release with Griess reagent method through LPS-induced in vitro inflammation model of RAW264. 7 cells. The results showed that Xixian Tongshuan Capsules extracts inhibited the secretion of NO by LPS-induced RAW264. 7 cells,indicating favorable anti-inflammatory activity. This research illuminates the mechanism of Xixian Tongshuan Capsules based on the PIN analysis at molecular network level,providing a scientific basis for its clinical application.
