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

Cortex Lycii is an herb from Asia mostly used in traditional Chinese medicine. Although its main purpose is not for lowering blood glucose levels, there are studies on Cortex Lycii with other substances which have proven it can lower glucose level in type 2 diabetes rat. Unlike other experiments, this experiment only used Cortex Lycii as a single unit to see if there was any effect on blood glucose level. Also an observation was done on if Cortex Lycii could reduce blood glucose level after ingesting a high glucose diet. Rattus norvegicus was used in this project and in order for the subject to consume Cortex Lycii, the herb was boiled and the liquid was given for consumption. In order to increase the rats’ glucose levels, corn syrup and white sugar were added to the mixture. The data showed significant decrease of blood glucose when Cortex Lycii liquid was ingested. This research has shown that Cortex Lycii can be a potential treatment for hyperglycemia or diabetes. With further research, there can be an alternative treatment rather than injecting external hormones (Insulin).展开更多
