Objectives: To study the inhibitory effects of grape juice on human prostate carcinoma PC-3 cells and its possible mechanism. Method: PC-3 cells were treated with grape juice in different concentration(16, 32, 64 ?l/ml) and resveratrol for 48 h; and the proliferation of PC -3 cells were measured by growth curve and MTT assay. TUNEL was used to observe the morphology of apoptotic cells and flow cytometry to analyze the PC-3 apoptosis. Results: Resveratrol and grape juice could markedly inhibit the proliferation of PC-3 cells, and TUNEL positive cells were detectable. The percentages of apoptotic cells were 6.0%,18.5%,30.0%, 12.7% in experimental groups and resveratrol group respectively. The effect on PC-3 cells was enhanced with increasing amount of grape juice. The effect of low dose group was weaker than that of resveratrol group, but medium and high dose groups were stronger. Conclusion: The anti-prostate cancer effect of grape juice is not only related to resveratrol contained but also to synergism with other components, and its mechanism might be the induction of PC-3 cells apoptosis.

Objective To assess the therapeutic effect of human adipose-derived mesenchymal stem cells on radiation-induced vascular injury in the small intestine of rat. Methods A total of 34 male Sprague-Dawley rats were enrolled in this study. To establish a model of radiation-induced intestinal injury, each rat was irradiated with 15 Gy in whole abdomen. 17 rats were randomly selected and infused intraperitoneally with passage 6 ( P6 ) Ad-MSCs, and the other 17 rats that received PBS were set as control. 10 days post-irradiation, the number of CD31+ endothelial cells in the small intestine villus was measured by flow-cytometry, the expressions of CD31, CD105 and isolectin-B4 in the na?ve endothelial cells with detected by IHC-staining, and the vascular integrity was evaluated by measuring VE-Cadherin. The origination of na?ve endothelial cells within injured intestine was also analyzed. In addition, total mRNA were extracted from irradiated small intestine to assay the expressions of VEGF, bFGF, Flk-1 and SDF-1 using quantitative Real-time PCR. Results Compared to the control, the amount of CD31-postive endothelial cells within irradiated intestine was significantly increased after Ad-MSCs infusion ( t=12?15, P<0?05). The microvascular density in the injured sites was also significantly increased by the infusion of Ad-MSCs (20 d:t=10?33, P<0. 05;30 d:t=32?85, P<0?05). Moreover, the expressions of VEGF, bFGF, Flk-1 and SDF-1 were significantly up-regulated after delivery of Ad-MSCs ( VEGF:t =10?34, bFGF:t=11?25,Flk-1:t=6?73, SDF-1:t=6?73, all P<0?05), which was beneficial in maintaining the integrity of intra-villus blood-vessels as well as promoting neovascularization in the injured sites. Conclusion Ad-MSCs had potentials in healing radiation-induced vascular injury in rat small intestine.

Objective To evaluate the therapeutic effect of adipose-derived mesenchymal stem cells on radiation enteritis.Methods A total of 52 male Sprague-Dawley rats were used in the present study.Herein,46 rats were randomly selected and irradiated with a dose of 15 Gy at their abdomens.Two hours post-irradiation,23 rats were randomly selected and infused intraperitoneally with adipose-derived mesenchymal stem cells in passage 6 from young-female donor.The other 23 rats were intraperitoneally infused with PBS.The rest 6 rats were set as normal control.During the first 10 days post-irradiation,peripheral blood-samples from irradiated rats were harvested for testing the levels of IL-10 in serum using ELISA assay.Additionally,after isolating the thymic cells and peripheral blood mononuclear cells,the percentages of CD4/CD25/Foxp(3)-positive regulatory T cells in thymus and peripheral blood were tested by flow-cytometry.Finally,infiltration of inflammatory cells and deposition of collagens within irradiated small intestine were analyzed by H&E staining and Masson Trichrome staining,respectively.Based on the MPO-immunohistochemistry staining,the type of infiltrated cells was identified.The Kaplan-Meier method was used for analyzing the survival rate of irradiated rats.Results During a period of 30 days post-irradiation,the irradiated rats receiving adipose-derived mesenchymal stem cells survived longer than those receiving PBS (t =4.53,P ＜ 0.05).Compared to the irradiated rats with PBS-treatment,adipose-derived mesenchymal stem cells could elevate the level of IL-10 in serum (7 d:t =13.93,P ＜ 0.05) and increase the percentages of CD4/CD25/Foxp(3)-positive regulatory T cells in both peripheral blood (3.5 d:t =7.72,7 d:t=11.11,10 d:t =6.99,P ＜0.05) and thymus (7 d:t =16.17,10 d:t =12.12,P＜ 0.05).Moreover,infiltration of inflammatory cells and deposition of collagens within irradiated small intestine were mitigated by adipose-derived mesenchymal stem cells.Conclusions Adipose-derived mesenchymal stem cells were capable of curing radiation enteritis.
