Objective To summarise the clinical characteristics, treatment and prognostic analysis of relapse in vaginal stump after treatment of cervical cancer and endometrial cancer, and to offer assistance to clinical diagnosis and treatment. Methods Clinical data of 28 patients (admitted in our hospital from Sepetember 2002 to July 2014) with cervical cancer and endometrial cancer after a simple hysterecto-my were retrospectively analyzed. According to the illness, the 28 cases were given partial vagina resection, total vaginal resection and ex-panded vaginal resection. Observe whether the prognostic is in correlation with lymph node metastasis, adjacent organs involvement, interval of recurrence and tissue differentiation degree. Results Median survival time of patients with well or poor differentiation were 40 and 15 months respectively(P<0. 05);and the 3 year survival rates were 66. 1% and 30. 7% respectively (P=0. 03). Median survival time of pa-tients with or without lymph node metastasis were 18 and 40 months respectively (P< 0. 05);and the 3 year survival rates were 0 and 24%respectively(P<0. 05). Median survival time for interval of recurrence of more than 24 months and less than or equal to 24 months were 28 and 16 months respectively (P<0. 05). Conclusion The surgical treatment of vaginal stump carcinoma is safe and effective, and the prog-nostic is in correlation with lymph node metastasis, adjacent organs involvement, interval of recurrence and tissue differentiation degree.

Objective To investigate levels of IL-17 and IL-22 mRNA in the blood of type 2 diabetes(T2DM)patients with the different stages of kidney injury and explore the relationship between the gene expression levels of IL-17,IL-22 and renal lesions in patients with diabetic nephropathy(DM).Methods Subjects included 60 T2DM patients with or without kidney injury and 20 normal controls(NC,n=20).Diabetes patients were divided into 3 groups by level of urinary albumin to creati-nine ratio (ACR):no proteinuria group (NA,ACR<30 mg/g,n=22),microalb uminuria group (MA,30 mg/g>ACR>300 mg/g,n=18)and diabetic nephropathy group (DN,ACR>300 mg/g,n=20).Quantitative Real-Time RT-PCR was used to detect IL-17 and IL-22 mRNA levels.Analysis differences of IL-17 and IL-22 mRNA levels among NA,MA,DN and NC groups.Results The levels of IL-17 and IL-22 mRNA were significantly higher in DN group than that in MA,NA and NC group (P <0.01,respectively),However,there were not significant difference among MA,NA and NC group (P >0.05,re-spectively).Conclusion Levels IL-17 and IL-22 mRNA were increased in blood of T2DM patients with nephropathy.IL-17 and IL-22 may play role in the pathogenicity of diabetic nephropathy.

Objective To investigate the effects of exogenous transforming growth factor-β3 (TGF-β3) on the expression of endogenous TGF-β3 and proliferation of rat hepatic stellate cells (HSC).MethodsRat HSC cells were seeded in 24-well plates and were divided into 2 groups.One group of cells were exposed to TGF-β3 of different concentrations (0.08,0.4,2,10 and 50 ng/ml) for 2 hours and then the cell culture supernatant was collected; the other group of cells were exposed to 10 ng/ml TGF-β3 and the cell culture supernatant was collected at different time point (0.25,0.5,1,2,4,8 and 13 h).The content TGF-β3 was determined by ELISA method.Some other HSC cells were seeded in 96-well plates and divided into 2 groups.One group of cells were cultured in the presence of exogenous TGF-β3 of different concentrations (0.001,0.005,0.02,0.08,0.32,1.25,5,20,100,500 ng/ml) for 24 hours and then the cell proliferation was detected; the other group of cells were treated with 5 ng/ml TGF-β3 for 24 and 48 hours.The cell proliferation was measured by MTT method.The HSC cell morphology of control group and TGF-β3 treated group was observed under inverted microscope. Results The endogenous TGF-β3 expression of HSC cells obviously increased after exogenous TGF β3 treated at 2 ng/ml and reached the peak at 3 hour [(0.845±0.028) ng/ml vs (0.026±0.021) ng/ml,F=210.168,P=0.00].Low concentrations of exogenous TGF-β3 did not affect the proliferation of HSC cells.Above 0.32 ng/ml,exogenous TGF-β3 could promote HSC proliferation.There was no dose-dependent relationship between HSC cell proliferation and the concentration of exogenous TGF-β3 (F=0.68,P=0.57).Under microscope,lhere was no significant difference in HSC cell morphology between control group and TGF-β3 treated group.Conclusions Exogenous TGF-β3 can promote the expression of endogenous TGF-β3 in HSC cells,and can promote HSC cell proliferation.There is no obvious effect of exogenous TGF-β3 on HSC morphology.

Natural products especially flavonoids are being explored for their therapeutic potentials in reducing bone loss and maintaining bone health. The present study is to investigate the effects of isoquercitrin from Craibiodendron yunnanense with different concentrations at 1 x 10(-4), 1 x 10(-5), 1 x 10(-6), 1 x 10(-7) mol x L(-1) on proliferation, differentiation and mineralization of MC3T3-E1. Cell proliferation was assessed by CCK-8 kit at 1, 3, 5 and 7 days of culture. Alkaline phosphatase (ALP) activity were performed qualitatively and quantitatively on day 7, and alizarin red S staining was employed to access the mineralization of cells on day 21. The osteogenic markers ALP, collagen type I (COL 1A1), runt-related transcription factor 2 (Runx-2) and Osterix were detected to analysis early osteogenic differentiation of cells on day 3 by RT-PCR. The results showed that isoquercitrin had a dose-dependent effect on the proliferation, osteogenic differentiation, mineralization and gene expression of MC3T3-E1 in the range from 1 x 10(-7) to 1 x 10(-5) mol x L(-1). At concentrations above 1 x 10(-4) mol x L(-1) isoquercitrin showed cytotoxicity, while 1 x 10(-6) mol x L(-1) is the optimal concentration of isoquercitrin to improve the osteoblastic activity. All these results implied that isoquercitrin might be the major composition of traditional Chinese medicine C. yunnanense to treat bone fractures.
