Methods:TCMSP and BATMAN-TCM online prediction database were used to screen and collect the active ingredients and targets of Mori cortex-Lycii cortex based on oral bioavailability and drug-like. Predictive analysis of disease targets was conducted through PubMed,GeneCards and DrugBank databases. The component-target regulation network was constructed by using Cytoscape 3.7.2 software,and the network topology of the core target was analyzed. Finally,the Bioconductor platform and R language were used for GO function analysis and KEGG pathway enrichment analysis,and the target-key pathway network diagram was constructed. Results:A total of 43 active components,including quercetin,kaempferol,acacetin,and beta-sitosterol,were identified with 242 potential targets. There were 3 271 pneumonia targets in children,among which the key targets were IL-6,AKT1,MAPK8,etc. There were 31 common targets of MMP9,TNF,AKT1 and so on. GO biological processes included the response to lipopolysaccharides,molecule of bacterial origin,metal ions,regulation of apoptotic signaling pathway,and T cell activation. The KEGG signaling pathways involved mainly included TNF,PI3 K/AKT and MAPK signaling pathway. Conclusion:Quercetin,kaempferol,beta-sitosterol and acacetin in Mori cortex-Lycii cortex may act on several signal transduction pathways such as TNF,PI3 K/AKT,MAPK signal pathways through AKT1,MAPK8,IL-6 and MMP9 targets,then treat children pneumonia via antiinflammation action. The results can provide references for the further study on the treatment of pneumonia in children with Mori Ccortex-Lycii cortex.展开更多

In Asian traditional medicine, Mori Cortex is widely used for the treatment of diabetes and hyperlipidemia. However, whether it has a therapeutic effect on T2 DM associated with NAFLD is still unknown. The present study showed that the oral treatment with Mori Cortex extract(MCE; 10 g·kg-1·d-1) lowered the blood lipid levels and reversed insulin resistance(IR) in high fat-diet/streptozotocin-induced type 2 diabetes in rats. The expression levels of sterol receptor element-binding protein-1 c(SREBP-1 c) and carbohydrate-responsive element binding protein(Ch REBP), which are involved in steatosis in NAFLD rats, were measured in the liver samples. MCE decreased the protein and m RNA expression levels of SREBP-1 c and Ch REBP. In conclusion, down-regulation of SREBP-1 c and Ch REBP might contribute to the protective effect of MCE on hepatic injury and IR in the rats with T2 DM associated with NAFLD.展开更多
