ABSTRACT
Objective: To explore the mechanism of Salvia miltiorrhiza in treatment of microcirculatory disturbance based on network pharmacology. Methods: The targets of S. miltiorrhiza’s active components for treatment of microcirculatory disturbance were screened and predicted by utilizing TCMSP, PubChem Search, Genecards database and Swiss target prediction online tool. Cytoscape 3.3.0 software was adopted to construct an active component-microcirculatory disturbance target network. The protein-protein interaction (PPI) network was established by using STRING database. DAVID database was used to analyze metabolism pathway in target gene ontology (GO) biological process, Kyoto encyclopedia of genes and gnomes (KEGG). Results: Totally 65 active components of S. miltiorrhiza and nine related targets were screened. GO and KEGG pathway enrichment analysis revealed that active components of S. miltiorrhiza participated in oxidation-reduction process, cellular calcium ion homeostasis and other biological processes, and S. miltiorrhiza may regulate VEGF signaling pathway, cholinergic synapse signal transduction, oxytocin signaling pathway, aldosterone-regulated sodium reabsorption pathway and so on. Conclusion: This study reflects the characteristics of multi-components, multi-targets, and multi-pathways of S. miltiorrhiza in the treatment of microcirculation disturbance, which may provide new ideas and methodology for further research on the treatment of microcirculatory disturbance using S. miltiorrhiza.
