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.

The Leguminosae perennial vines of Callerya and Millettia have many species and wide distribution, not only can be used for medicines, but also they have ornamental and insecticidal effects. With increasing demand for Spatholobi Caulis, and the reserves of wild medicinal materials are on the verge of exhaustion, resulting in the increasing number of mixtures and substitutes in the market, which makes it urgent to study the origin of Spatholobi Caulis. By referring to related literature, there are three major origins of Spatholobi Caulis, including Callerya, Millettia and Spatholobus. Callerya is separated from Millettia, they are divided and united for many times, now the official website of Flora of China has accepted the revision of them as two genera. This paper intends to compare the chemical components and pharmacodynamic effects of Callerya and Millettia, aiming to explore the similarities and differences between the two genera, so as to determine the rationality and necessity of separating Callerya from Millettia. After comparing, it was found that the chemical composition and pharmacodynamic effects of the two genera were different, which supported the separation of Callerya from Millettia, and it was not recommended to mix use of them.
