Objective : To investigate the protective effect of adiponectin APN on myocardial injury caused by sep⁃ sis and its possible mechanism. : Methods Results : Compared with sham group , the expression of Bax , cleaved Caspase3 protein increased and the expression of Bcl⁃2 protein decreased in LPS group. Compared with LPS group , the injury in APN + LPS group was significantly alleviated , showing that the expression of Bax , cleaved caspase3 protein decreased and the expression of Bcl⁃2 protein increased. Meanwhile , compared with sham group , the expression of Cx43 increased in LPS group and decreased in APN + LPS group. Conclusion Adiponectin can attenuate LPS⁃induced cardiac injury in septic mice. The mechanism may be through the inhibition of apoptotic signal pathway and the expression of Cx43.

【Objective】 To study the mechanism of Apocynum leaves in the treatment of sepsis by network pharmacology method in order to explore the multi-dimensional research method of Xinjiang ethnic medicine treatment of infectious diseases and provide scientific theoretical basis for clinical medication. 【Methods】 TCMSP and literature collection were used to screen the main active components of Apocynum venetum leaf, and target prediction analysis was conducted by SwissTarget Prediction database. We used Genecards database to screen relevant targets for sepsis, used Omicshare to calculate Venn figure of the intersection targets, constructed the protein-protein interaction network diagram in the STRING database, used Ensembl for name conversion of protein targets, then entered Omicshare server for Go function and KEGG pathway enrichment of dynamic analysis. Last we used Cytoscape3.6.0 software to construct "Apocynum venetum leaf-the active ingredients-targets-Go-KEGG-sepsis" network to explore the mechanism of action of Apocynum’s resistance to sepsis. 【Results】 Kaferol, luteolin, proanthocyanidin B1 and phytosterol in Apocynum venetum leaves may treat sepsis by controlling signal transduction, regulating hormone level and anti-infection through predictive biological targets such as Akt1, VEGFA, MAPK3, EGFR, Src and PTGS2. They can play an important role through VEGF, EGFR, erbB, HIF-1, RAS and other enrichment pathways. 【Conclusion】 The active components of Apocynum venetum leaves can fight against sepsis through multiple targets and multiple pathways.
