Abstract:
ObjectiveBased on the protective effect of Dengzhan Shengmai capsules （DZSM） on chronic cerebral hypoperfusion （CCH）， network pharmacology was employed to investigate the molecular mechanism. MethodCCH model was established by right common carotid artery ligation. The mice were divided into sham operation group， model group， ginaton group （48 mg·kg-1）， DZSM low- and high-dose groups （0.040 5， 0.162 g·kg-1）. The efficacy was evaluated by the Morris water maze test and open-field test. The underlying mechanism of DZSM for CCH was analyzed by network pharmacology and verified by molecular biology experiments. PubChem， GeneCards， Metascape and other databases were used for targets collection and enrichment analysis. Besides， the association of ingredients targets of DZSM with disease targets of CCH， core target network and chemical components-core targets-pathways network were constructed by STRING 11.0 and Cytoscape 3.7.1. ResultThe escape latency of CCH mice significantly shortened on the 3rd to 5th day after DZSM low-dose treatment， the crossing times， time spent in the target quadrant， movement distance and distance in the central region of CCH mice significantly increased after DZSM low-dose and high-dose treatment. The results of network pharmacology indicated that DZSM might play a key role by regulating inflammatory response， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， cytokine-cytokine receptor interaction， tumor necrosis factor （TNF） signaling pathway， blood circulation， angiogenesis， extracellular matrix and other related biological processes and pathways， and acting as targets such as interleukin-6 （IL-6）， TNF， insulin-like growth factor 1 （IGF1）， vascular endothelial growth factor A （VEGFA）， epidermal growth factor （EGF）. The results of biological experiments showed that DZSM could reduce the expression of IL-6 in brain tissue of CCH mice. ConclusionDZSM provides a protective effect during CCH， and its multi-component， multi-pathway， multi-target mechanism is also revealed， which provides a basis for further study of the mechanism.
