ABSTRACT

AIM To study the efficacy of different extractions of Huidouba,a Tibetan medicine to mice with type Ⅱ diabetic kidney disease (DKD).METHODS The type Ⅱ DKD mice models induced by the injection of streptozotocin (STZ) on base of high glucose and high fat diet subsequently treated with different extractions of Huidouba were studied to investigate the protective effects of Huidouba on renal injury.The mice were given high dose (200 mg/kg) and low dose (100 mg/kg) of Huidouba ethanol extract,Huidouba water extract and Huidouba polysaccharide respectively for 8 weeks.Their serum creatinine (SCr),blood urea nitrogen (BUN),urine protein (mg/24 h),glycosylated serum protein (Gsp) and advanced glycation end products (AGEs),their histological changes of renal pathology were detected and analyzed.Meanwhile their protein levels of fibronectin (FN),intercellular adhesion factor (ICAM-1) and transforming growth factor (TGF-β1) were identified by Western blot.RESULTS The different extractions of Huidouba,demonstrating a portfolio of capacity in decreasing levels of serum glucose and AGEs,inhibiting the expression of target protein,alleviating the glomerular basement membrane thickening,improving mesangial matrix,renal tubular and epithelial cells degeneration and other pathological conditions,improved the renal function of DKD mice.CONCLUSION The three extractions of Huidouba highlight the renal improvements in type Ⅱ DKD mice.

ABSTRACT

The aim of this paper was to find out the active components of Epimedium brevicornum using network pharmacology, and find the potential targets and mechanisms. The TCMSP database was used to screen the active ingredients, and TTD and DrugBank databases were used to predict the potential targets with the literature mining. The pathway annotation was used to enrich and analyze the active ingredients and potential targets of E. brevicornum. The results showed that E. brevicornum had34 potential target active ingredients, including 21 flavones components, such as icariin, epimedin A, epimedin B, epimedin C, Yinyanghuo A, Yinyanghuo C and so on, 2 lignans involved in (+)-cycloolivil and olivil, 3 sterols consisting of sitosterol, 24-epicampesterol and poriferast-5-en-3beta-ol. The main predicted targets included Ptgs2, NCOA6, RANK, OPG, WNT9B, PTH1R, BMPs, SMAD4A and so on. There were 88 signaling pathways involved in 10 signaling pathways which was related to inflammation, such as NF-kappa B signaling pathway, T cell receptor signaling pathway, IL-17 signaling pathway and 10 pathways which was related to cancer included breast cancer, bladder cancer, pancreatic cancer and so on, and estrogen related signaling pathways included estrogen signaling pathway. This laid the foundation for the discovery of the active components of Epimedium and the study on its mechanism of action.
