Study on mechanism of Yangxue Qingnao Granule for the treatment of vascular dementia disease based on network pharmacology and bioinformatics / 国际中医中药杂志

ABSTRACT

Objective:To explore the possible mechanism of Yangxue Qingnao Granule for the treatment of vascular dementia (VaD) based on network pharmacology and bioinformatics.Methods:The active components and potential targets of Yangxue Qingnao Granule in the treatment of VaD were obtained from TCMSP database, BATMAN-TCM database, GEO database and OMIM database, etc. The heatmap was visualized by using the pheatmap packages in R. Cytoscape 3.8.2 software and the CytoNCA plugin were utilized to build a network of "Chinese materia medica-active component-potential target". CytoNCA plug-in was used to analyze PPI network topology. Metascape was used for GO and KEGG pathway enrichment analyses. Finally, AutoDock Vina 1.5.6 software was applied to construct molecular docking between the active components and potential core targets. Resuls A total of 135 active components of Yangxue Qingnao Granule were screened and 186 potential targets of Yangxue Qingnao Granule against VaD were obtained. GO function enrichment analysis found protein kinase binding, transcription factor binding and other biological functions. KEGG pathway enrichment analysis identified PI3K-Akt signaling pathway, AGE-RAGE signaling pathway, TNF signaling pathway, etc. Molecular docking showed that the main active components of Yangxue Qingnao Granule had good binding activity with the potential targets. Conclusion:Yangxue Qingnao Granule has the characteristics of multi-targets and multi- pathways in the treatment of VaD. It may play a therapeutic role in VaD by inhibiting neuronal apoptosis and reducing inflammatory response.
