Abstract: 【Objective】 The experiment was aimed to study the effective components and corresponding gene targets of Salvia miltiorrhiza and Ligusticum chuanxiong in the treatment of ischemic stroke through network pharmacology, and to explore its mechanism of action.【Method】 Using Traditional Chinese Medicine System Pharmacology Enumeration Platform (TCMSP), GeneCards and OMIM database, the potential targets of Salvia miltiorrhiza and Ligusticum chuanxiong for the treatment of ischemic stroke were screened, and GO function and KEGG pathway enrichment analysis were carried out.The sham-operated group, the model group, and the low-dose, medium-dose and high-dose Salvia miltiorrhiza-Ligusticum chuanxiong groups were set up respectively, and the cerebral ischemia-reperfusion model rats prepared by suture were intervened by means of preventive and therapeutic administration.The 24-h blood reperfusion model rats were scored for neurological function by Zea-longa method, and hematoxylin-eosin (HE) staining was used to observe the pathological changes of brain tissue for preliminary verification.【Result】 In this study, a total of 72 main active ingredients of Salvia miltiorrhiza-Ligusticum chuanxiong pairs were screened, 7 from Ligusticum chuanxiong, 65 from Salvia miltiorrhiza, and 1 972 target genes for ischemic stroke.There were 94 common targets, including IL6, IL10, TNF, MMP9, VEGFA, CASP3, etc.The results of GO function and KEGG pathway enrichment suggested that the treatment of ischemic stroke by Salvia miltiorrhiza-Ligusticum chuanxiong was related to PI3K-Akt, cGMP-PKG, VEGF and other signal pathways.Animal experiments showed that Salvia miltiorrhiza-Ligusticum chuanxiong could reduce the pathological changes of brain tissue, reduce neurological deficits, and improve cerebral ischemia-reperfusion injury.【Conclusion】 Salvia miltiorrhiza-Ligusticum chuanxiong medicine pair might improve cerebral ischemia-reperfusion injury through PI3K/Akt signaling pathway, and played an anti-apoptotic effect.
