Methods: The active ingredients and related targets of Chuanxiong and Angelica sinensis were screened by TCMSP database, and the related targets were obtained by searching GeneCard, OMIM, DrugBank and Disgenet databases. The Venny2.1 Venn diagram was used to obtain the common targets of the drugs and diseases, and then entered into the Cytoscape 3.9.1 software to draw the network diagram of “Angelica sinensis and Rhizoma Ligustici Chuanxiong - common targets - acute ischaemic stroke”. The protein interaction PPI network was constructed by using STRING database and Cytoscape 3.9.1 software, and the gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were carried out through DAVID database, and the bubble diagrams of the enrichment analyses were made by using Microbiology Letter. The molecular docking was verified by AutoDock software and visualised by Pymol software. Result: Nine active ingredients and 53 potential targets of Angelica sinensis and Rhizoma Ligustici Chuanxiong in the treatment of acute ischemic stroke, and the key targets were JUN, ESR1, CASP3 and PTGS2. Conclusion: The pair of Angelica sinensis and Rhizoma Ligustici Chuanxiong can be used in the treatment of acute ischemic stroke through a variety of pathways, active ingredients and targets. The therapeutic effects of this drug on acute ischaemic stroke are mainly related to the calcium signaling pathway and the phosphatidylinositol 3-kinase (PI3K)-AKT pathway, which provides theoretical support for the subsequent study of the mechanism of this drug in the treatment of acute ischaemic stroke.展开更多
