AIM:To investigate the mechanism of action of Tamarix chinensis Lour.on streptozotocin-induced type 2 diabetes mellitus(T2DM)through network pharmacology,molecular docking and ex-perimental validation.METHODS:Using the TCSMP database and Swiss Target Prediction tools screen the active components and predict potential tar-gets in Tamarix chinensis Lour..Retrieving potential disease targets associated with T2DM from data-bases such as GeneCards,OMIM,and DisGeNET.The intersection targets of Tamarix chinensis Lour.and T2DM disease was obtained through Venny platform.The STRING database was used to con-structed PPI network,and Cytoscape 3.8.0 soft-ware was use to visualized.GO function enrich-ment and KEGG pathway enrichment analysis were performed through the Metascape database.Dock-ing of important target proteins and compounds was carried out by AutoDock software.SPF grade male rats were randomly divided into normal group,model group,MET group(88.5 mg/kg),TE high-dose(800 mg/kg)group,TE medium-dose(400 mg/kg)group and TE low-dose(200 mg/kg)group(n=10).High-fat and high sugar feed com-bined with low dose STZ(45 mg/kg)was used to in-duce T2DM rat model,and the rats were adminis-tered orally for 5 weeks.Fasting blood glucose(FBG),insulin(FINS)level and HOMA-IR index,bio-chemical indicators[superoxide dismutase(SOD),malondialdehyde(MDA),glycosylated hemoglobin A1c(HbA1c)and inflammatory factor[interleukin-1β(IL-1β),tumor necrosis factor α(TNF-α),vascu-lar cell adhesion molecular(VCAM-1)levels of the rats were also observed;morphological changes of renal tissue was observe by HE staining.RESULTS:Based on the screening conditions of oral bioavail-ability(OB)≥ 30％and drug like properties(DL)≥0.18,a total of 19 main active ingredients with po-tential therapeutic effects on T2DM were screened from Tamarix chinensis Lour.,including ergosta-5,24(28)-dien-3,7,16-triol,quercetin-3,3'-dimethyl ether,kaempferol,quercetin,and others.By analyz-ing the potential targets of Tamarix chinensis Lour.for treating T2DM,a total of 185 potential target genes were screened,including SRC,EGFR,HSP90AA1,AKT1,ESR1,H1F1A,TNF,PIK3R1,etc,in-volving cancer signaling pathways,insulin resis-tance,MAPK signaling pathways,PI3K Akt signaling pathways,etc.Molecular docking results showed that the binding energies were all less than-5.0 kcal/mol,indicating that a strong binding abili-ty between the active ingredients screened by Tam-arix chinensis Lour.and the potential targets for the treatment of T2DM.The animal experiment re-sults showed that compared with the model group,the weight loss of rats in the MET and TE groups was slowed down,and the levels of FBG,FINS,MDA,HbA1c,IL-1β,TNF-α,VCAM-1,HOMA-IR in-dex were reduced,the SOD level was increased,and the differences were statistically significant(P＜0.05,P＜0.01),Renal tissue cellular morphology also showed notable improvement.Most importantly,all these results demonstrating dose-dependent ef-fects.CONCLUSION:Tamarix chinensis Lour.dis-plays a significant therapeutic effect on T2DM through multi-component,multi-target,and multi-pathway synergistic actions to improve blood glu-cose levels.The findings of this study provide a the-oretical basis for the clinical application of Tamarix chinensis Lour.in the treatment of T2DM.

It has been popular and challenging to undertake researches on the delay of acquired resistance of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI). As key cells for tumor initiation, cancer stem cells (CSC) play an important role in the process of resistance to EGFR-TKI. Although preliminary studies found that traditional Chinese medicine (TCM) could inhibit CSC properties and delay EGFR-TKI resistance, the specific molecular mechanism remains unclear. By summarizing the empirical syndrome treatment of EGFR-TKI resistance via TCM and combining recent researches on TCM intervention in CSC to delay EGFR-TKI resistance, this review discussed the potential molecular pathways and mechanisms of deceleration in resistance to EGFR-TKI by TCM via inhibiting CSC characteristics, in order to expand the research ideas of TCM in combination with targeted therapy.
