Objective To investigate the effects of human umbilical mesenchymal stem cells (hUCMSCs) on Wistar rat models of stress urinary incontinence and its possible mechanism.Methods hUCMSCs cells were separated and extracted from human umbilical cord of cesarean delivery of full-term pregnancy women.The models of stress urinary incontinence (SUI) of Wistar rats were established by imitating delivery damage and ovary removing surgery,and then randomly divided into three groups:model group,transforming growth factor-β1 (TGF-β31) group,hUCMSCs group,and normal rats as normal group;and every group included ten rats.Maximal bladder capacity (MBC),leak point pressure (LPP),abdominal leak point pressure (ALPP),and sneezing experiment of rats including normal rats,model rats and model rats accepted TGF-β1 or hUCMSCs treatment were examined.When the treatment accomplished,the rats were killed and urethral sphincter were separated and examined by hematoxylin eosin (HE) staining and the proteins of troponin Ⅰ (TnI),troponin C (TnC),troponin T (TnT),tropomyosin (Tm),actin (AT),myosin heavy chain (MHC) and myosin light chain (MLC) of urethral sphincter was detected with Western blot method.Results The cells of hUCMSCs were extracted and authenticated,SUI models of Wistar rats were successfully established and authenticated.Compared to model group and TGF-β1 group,the MBC,LPP and ALPP of hUCMSCs group dramatically improved (P ＜ 0.05),while the positive rate of sneezing experiment significantly dropped (P ＜ 0.05).HE staining showed urethral sphincter became attenuation,fracture,sparse and disorder,simultaneously the proteins of TnI,TnC,TnT,Tm,MHC and MLC of urethral sphincter reduced (P ＜ 0.05).While the damaged urethral sphincter basically restored the normal structure and the proteins of TnI,TnC,TnT,Tm,MHC and MLC of urethral sphincter up-regulated through hUCMSCs treatment (P ＜ 0.05).Conclusions The treatment of hUCMSCs translation could observably improve the clinic symptoms of SUI Wistar rat models,and its mechanism may be related to enhancement of the protein expression of TnI,TnC,TnT,Tm,MHC and MLC of urethral sphincter,and were involved in the rehabilitation and reconstruction of urethral sphincter.

OBJECTIVETo discuss the mechanism of gambogenic acid (GNA) in inducing the apoptosis of melanoma B16 cells.

METHODThe inhibitory effect of GNA on the proliferation of B16 cells was measured by the methyl thiazolyl tetrazolium (MTT) assay. The effect of GNA on B16 cells was detected by the Hoechst 33258 staining. The transmission electron microscopy was used to observe the ultra-structure changes of B16 cells. The changes in PI3K, p-PI3K, Akt, p-Akt, p-mTOR, PTEN proteins were detected by the Western blotting to discuss the molecular mechanism of GNA in inducing the apoptosis of B16 cells.

RESULTGNA showed a significant inhibitory effect in the growth and proliferation of melanoma B16 cells. The cell viability remarkably decreased with the increase of GNA concentration and the extension of the action time. The results of the Hoechst 33258 staining showed that cells processed with GNA demonstrated apparent apoptotic characteristics. Under the transmission electron microscope, B16 cells, after being treated with GNA, showed obvious morphological changes of apoptosis. The Western blot showed a time-dependent reduction in the p-PI3K and p-Akt protein expressions, with no change in p-PI3K and p-Akt protein expression quantities. The p-mTOR protein expression decreased with the extension of time, where as the PTEN protein expression showed a time-dependent increase.

CONCLUSIONGNA could inhibit the proliferation of melanoma B16 cells and induce their apoptosis within certain time and concentration ranges. Its mechanism in inducing the cell apoptosis may be related to PI3K/Akt/mTOR signaling pathways.
