Mechanism and compatibility efficacy of Astragali Radix-Chuanxiong Rhizoma drug pair in treating ischemic stroke based on network regulation
Based on the association network of"drug pair-disease",the effect characteristics of Astragali Radix-Chuanxiong Rhizo-ma drug pair in the treatment of ischemic stroke(IS)with Qi deficiency and blood stasis and the matching mechanism of the two were explored.Through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and SwissTargetPre-diction Database,the effective chemical components of the drug pair were screened,and the candidate targets were predicted.Databa-ses such as GeneCards,DrugBank,Online Mendelian Inheritance in Man(OMIM),and Therapeutic Target Database(TTD)were searched to obtain gene targets related to IS.Through STRING and Cytoscape 3.9.1 software,the protein-protein interaction(PPI)network was constructed by using the interaction information of disease syndrome-related genes and candidate targets of drug pairs,and the core targets were screened according to the network topological feature values.Based on the Metascape platform and DAVID data-base,the biomolecular interaction information was integrated to analyze the Kyoto Encyclopedia of Genes and Genomes(KEGG)and mine biological functions,so as to further explore the mechanism of action and compatibility characteristics of Astragali Radix-Chuan-xiong Rhizoma.The results showed that the candidate biological process was mainly involved in the regulation of functional modules such as immune,blood circulation,neurotransmitter,and oxidative stress,and it was enriched in lipid and atherosclerosis,calcium signaling pathway,and platelet activation.Astragali Radix and Chuanxiong Rhizoma have their own characteristics.Astragali Radix has a regulatory response to growth factors while maintaining the body's immune balance,while Chuanxiong Rhizoma mainly improves the circulatory system and participates in hormone metabolism,so as to indicate the compatibility mechanism of Astragali Radix-Chuanxiong Rhizoma drug pair for multi-target and multi-pathway synergistic treatment of IS.Through further experimental verification,it was found that the Astragali Radix-Chuanxiong Rhizoma drug pair could significantly down-regulate the expression of key targets including TLR4,NF-κB,IL-1β,F2R,PLCβ1,and MYLK.This study preliminarily reveals that the Astragali Radix-Chuanxiong Rhizoma drug pair may play the three replenishing effects of promoting blood circulation,benefiting Qi,and clearing collaterals by correcting immune di-sorders,blood circulation disorders,and inflammation,which provide support for the clinical research on the subsequent improvement of Qi deficiency and blood stasis in the treatment of IS and provide a new idea for the analysis of modern biological connotation of the compatibility of seven emotions of traditional Chinese medicine.
