ObjectiveTo investigate the expression of TESTIN gene in endometrial carcinoma and explore the functions of this gene in tumor development and progression.MethodsqRT-PCR and immunochemical staining assay were used to determine the mRNA and protein level of TESTIN in the tumor tissues,and the relationship between TESTIN expression and clinical pathology characteristics was analyzed.Results Compared to normal tissue,76.5％ (52/68) tumor tissues showed TESTIN reduced ( P ＜ 0.01 ),furthermore,this reduction in the subgroup of endometrioid adenocarcinoma was significant,but it was rarely observed in the subgroup of serous papillary adenocarcinoma.ConclusionsTESTIN was obviously down regulated in endometrail carcinoma,especially in endometrioid adenocarcinoma,which indicated TESTIN played an important role in tumorigenesis of uterine.

Objective To discuss clinical effect and feasibility of laparoscopic pelvic lymphadendenectomy assisted radical vaginal hysterectomy (LARVH) in the treatment of cervical cancer. Methods Laparoscopic pelvic lymphadendenectomy assisted radical vaginal hysteretomy was performed in 38 patients with cervical cancer. The operative quality and postoperative recovery effects were analyzed. Results All 38 patients were successfully performed with LARVH and no complications. The radical vaginal hysteretomy were performed in all of patients, 21.4±2.2 pelvic lymph nodes were removed. The average duration of surgery was (240±25.6) min and the average hemorrhage was (340±40.2) ml. There were 7 patients who needed blood transfusion during operation. After operation, the mean time for passage of gas by anus was (2±0.26) days, and the mean recovery time of bladder function was (10.5±1.3) days. Patients were discharged after (9.2±1.1) days on average. 38 patients had no complication. Conclusions For the treatment of uterine neoplasm, LARVH decreased operative damage with more short recovery time, same operative extent as laparotomy. It is an ideal way to treat uterine neoplasm currently.

Objective To explore the immunosuppression effects,outcomes and clinical significance of mesenchymal stem cells (MSCs) transplantation in burn treatment by comparing the levels of WBC,C-reaction protein (CRP),interferon-γ(IFN-γ),interferon-o (TNF-α),interleukin-6 (IL-6),interleukin-10 (IL-10) between control burn models and models conducting MSCs transplantation.Methods After stripping Wharton's Jelly from the neonatal umbilical cord,MSCs was cultured and expanded.Burn models were constructed in male SD rats weighted at (200± 5) g,and randomly grouped for control and MSCs transplantation.The rats in transplantation group were injected subcutaneously with hUCMSCs (1.5× 106) at 24 h after burning.The content of WBC,CRP,IFN-γ,TNF-α,IL-6,IL-10 in blood samples at 0,1,2,3,5 and 7 d after burning were detected by enzyme-linked immunosorbent assay (ELISA).The ELISA results,the wound healing rate at 7,14,21 and 28 d,as well as wound healing time were compared and analyzed statistically by ANOVA between the two groups.Results WBC in control group increased significantly at 1 and 2 d,and CRP in control group increased substantially at 2 and 3 d.IFN-% IL-6 and IL-10 levels in serum showed increase on 5 d,and TNF-α arrived at its peak value at 7 d.By contrast,WBC,CRP,TNF-α,IL-6 and IL-10 of the MSCs transplantation group showed slightly increase after burning and the differences were convinced by statistical analysis,while IFN-γ showed little difference among the two groups.The MSCs transplantation group also showed significantly higher wound healing rate at 14,21,28 d and shorter wound healing time than that of the control.Conclusions MSCs transplantation can suppress the over-inflammatory response by significantly mediating the inflammatory cytokines as WBC,CRP,TNF-α,IL-6,IL-10 in burn.IFN-γseems not affected by MSCs transplantation.MSCs would be suitable to promote wound healing and repair in burn,which is achieved not only by differentiation and paracrine,but also by subtle immunoregulation.

Objective To observe the effect of adding on glimepiride in treating type 2 diabetic patients who had suffered the disease for more than 10 years and were poorly controlled with insulin combined with nonsulfonylureas drugs. Methods Seventy-five type 2 diabetic patients poorly controlled with insulin combined with non-sulfonylureas drugs were randomly divided into glimepiride-added group (INS+GM, n = 39 )and continuation of insulin group ( INS, n = 35 ). HbA1c, plasma glucose, daily insulin dose, number of hypoglycemic events, body weight, plasma lipid concentration,and high-sensitive C-reactive protein (hs-CRP)were recorded at weeks 0, 12,and 24. The levels of plasma free fatty acid ( FFA), adiponectin, and tumor necrosis factor-α ( TNF-α ) were measured before and 24 weeks after the therapy. Results At 12 and 24 weeks, fasting blood glucose, 2 h postprandial blood glucose,and HbA1c were improved in INS+GM group more markedly than in INS group, and daily insulin dose and body weight were decreased in INS+GM compared with INS ( P＜0. 05 ). The number of hypoglycemic events and plasma lipid concentration did not differ between two groups ( P＜0.05 ). The levels of plasma FFA,TNF-α,hs-CRP, and HOMA-IR were lower in INS+GM than INS ( P＜0.05 ), the adiponectin was higher in INS + GM than INS ( P ＜ 0.05 ). Conclusion Adding glimepiride to insulin therapy resulted in a sustained better glycemic control with less insulin daily dose, decresed body weight, and no increase in hypoglycemic events as compared with the continuing insulin therapy group. Increased adiponectin, as well as decreased plasma FFA and TNF-α may underlie the improvement of insulin resistance with glimepiride treatment.

Objective To investigate the effects of peptide-binding domain (PBD) of heat shock protein (HSP) 72 on epithelial to mesenchymal transition (EMT) in rat renal tubular epithelial cells.Methods The expressions of wild-type HSP72,mutant of HSP72 lacking peptide binding domain (HSP72-△PBD) and HSP72-PBD were induced by plasmid transfection.NRK-52E ceils were stimulated by TGF-β1 for 48 h.The expressions of α-smooth muscle actin (α-SMA),E-cadherin,HSP72 and Smad3/p-Smad3 were detected by Western blot and immunofluorescence.Results After NRK-52E cells were stimulated by TGF-β 1 (10 μg/L) for 48 h,the expression of α-SMA was increased and the protein level of E-cadherin was decreased.Western blotting and immunofluorescence showed that over-expression of both HSP72 and PBD inhibited TGF-β1-induced up-regulation of protein α-SMA expression,down-regulation of protein E-cadherin.However,overexpression of HSP72-△PBD did not change the protein level of E-cadherin and α-SMA.In addition,over-expression of HSP72 and PBD significantly inhibited the phosphorylation of Smad3.Conclusion Inhibition of Smad3 activation and EMT by HSP72 is associated with the function of PBD.

Objective To study the application of standardized patients practice and agent physician system in digestion medical clinical practice. Methods One hundred and fifty five-year-clinical medical students who began digestion medical clinical practice from 2008 to 2009 were selected and randomly divided into teaching reform group and control group, each group containing 75 people. According to teaching reform group students' willingness and through the selection, 69 were identified as agent physician. Standardized patients and agent physician simulation clinical training were applied in the teaching reform group while conventional teaching methods were used in the control group. Sta-tistical analysis of the experimental data was conducted using SPSS 11.0 statistical package. Measure-ment data use independent-samples t test and rank sum test was used for heterogeneity of variance. Results Teaching reform group students' inquiry contents and skills scores for each project were higher than those of control group and the score difference was statistically significant (P<0.05) in chronological order, the transition language, interrogation schedule, repeated questions, summary records, citing verification, instrumentation courtesy, friendly behavior, praise and encouragement, eliciting the patient's views, concerns about the effects of disease, care and support and assistance aspects. After the end of the third internship, two groups were compared in operation results, reform history collection, physical examination skills group score and the excellent and good rate being higher (P=0.002, 0.001). After three times' practice, teaching group students' scoring pass rate in medical ethics demeanor, interrogation techniques and physical examination skills, case analysis is higher than that of the control group students, and the difference was statistically significant(P<0.05). Conclusion Application of standardized patients and implementing agency resident simulation clinical training in the guide teaching of digestion department of internal medicine has achieved good effect.

Objective To observe the difference between skeletal age of hand and wrist and chronological age and explore the reliability of CHN radiographic atlas method to assess the skeletal age of hand and wrist in children and adolescent.Methods Total 1397 healthy children (666 boys,731 girls;age range,1.0-18.0 years old) with hand and wrist injury from 2007 to 2011 were selected.Forty groups (n =20 for boys and girls,respectively) were classified according to CHN radiographic atlas method.The radiographs of hand and wrist were assessed by CHN radiographic atlas method,the relations between skeletal age and chronological age were investigated by using Wilcoxon signed ranks test.Results According to the CHN radiographic atlas method,the difference in 1.0 to 3.9 years old,7.0 to 7.9 years old and 9.0 to 15.9 years old boy groups between skeletal age and the chronological age had statistical significance (P ＜0.05) ; the difference in 1.0 to 2.9 years old,8.0 to 11.9 years old,12.6 to 14.9 years old,and 17.0 to 18.0 years old girl groups between skeletal age and the chronological age had statistical significance (P ＜ 0.05).Besides,these skeletal age was higher than the chronological age.Conclusions Skeletal age assessed by the CHN radiographic atlas method in a majority of age groups was higher than chronological age.It should be cautious to estimate the contemporary Chinese children skeletal age of hand and wrist when using the CHN radiographic atlas method.

Objecfive To investigate the change of V-ATPase B subunits on epithelial to mesenchymal transition (EMT)in rat renal tubular epithelial cells (NRK52E) stimulated by transforming growth factor β1 (TGF-β1). Methods NRK52E cells were stimulated by TGF-β1 (10 μg/L)for O h(control),12 h,24 h,48 h,72 h after sefrum-free culture for 24 h.The mRNA and protein expression of E-cadherin,α-SMA,B2 and B1 subunits of V-ATPase were detected by real-time PCR,Western blotting and immunofluorescence. Results After stimulated by TGF-β1 (10 μg/L)for 48 h,the expression of α-SMA was markedly increased(P<0.05),but the expression of E-cadherin was dramatically decreased(P<0.05).Meanwhile,the expressions of V-ATPase subunit B2 was significantly increased (P<0.05).However,the B1 subunit distributed rarely in NRK 52E cells,and did not increase after TGF-β1 stimulation.Double-label immunofluoerscence staining also showed that the V-ATPase B2 subunit was increased in the cytosol.tending to accumulate to the cell membrane after TGF-β1 stimulation. Conclusions The main isoform of V-ATPase distributed in NRK52E cells is B2 subunit.B2 subunit is increased alone with TGF-β1-induced EMT.It may suggest that V-ATPase B2 subunit may play a potential role in TGF-β1-induced tubular EMT and renal fibrosis.

Objective To explore the effect of Numb on tubular epithelial-to-mesenchymal transition (EMT) in rat proximal epithelial cells. Methods NRK52E cells were treated with different concentrations of recombinant human transforming growth factor-β1 (TGF-β1) (0, 1, 5, 10, 15, 20 μg/L) for 48 h or 10 μg/L TGF-β1 for different times (0, 24, 48, 72 h) in vitro. The expressions of E-cadherin, a-smooth muscle actin(α-SMA) and Numb in NRK 52E cells were detected by RT-PCR, Western blot and immunofluorescence staining. Meanwhile Numb siRNA oligo was transfected into NRK 52E cells with lipofectamine before TGF-β1 treatment, then Western blot was applied to detect the protein expression of E-cadherin, α-SMA and Numb in NRK52E cells. Results TGF-β1 could induce EMT in NRK52E cells in dose- and time-dependent manner. During the progress of TGF-β1-induced EMT, the protein expression of Numb in 5, 10, 15, 20 μg/L group was 1.33 folds (P=0.024), 1.39 folds (P=0.035), 1.45 folds (P=0.025), 1.51 folds (P=0.000) respectively as compared to 0 μg/L group. Likewise, the protein and mRNA expression of Numb in 24 h, 48 h, 72 h group was 1.48 folds (P=0.046) and 1.56 folds (P=0.012), 1.54 folds (P=0.011) and 1.82 folds (P=0.008), 1.79 folds (P=0.028) and 1.82 folds (P=0.002) respectively as compared to 0 h group. Moreover, large amount of Numb was accumulated in the cytoplasm. Down-regulation of Numb expression by siRNA transfection did not influence the basal expression of E-cadherin and α-SMA in NRK 52E cells, but attenuated the progression of EMT in NRK52E cells induced by TGF-β1. The up-regulation of α-SMA protein was reduced to 18.1% (P=0.004) while the down-regulation of E-cadherin protein was reversed to 2.19 folds (P=0.004). Conclusion Numb can promote EMT in rat proximal epithelial cells.
