Objective To elucidate the expression pattern of E-cadherin/catenin adhesion complex and its association with pathologic features in nasopharyngeal carcinoma(NPC).Methods Fifty-two non-keratinizing NPC specimens with adjacent non-neoplastic mucosa were examined for E-cadherin,?-CATenin,?-CATenin.Results Abnormal expression rate of E-cadherin,?-catenin and ?-catenin in NPCs were 48.1%(25/52),32.7%(17/52) and 34.6%(18/52),respectively,whereas all adjacent non-neoplastic tissues normally expressed these proteins.Difference of expression of E-cadherin,?-catenin and ?-catenin between tumor tissues and non-cancerous tissues was statistically significant(P

Background Diabetic retinopathy (DR) is one of the most important microvascular complications of diabetes,which has become one of the leading causes of blindness.Neovascularization is the main pathological manifestations of DR,but its mechanism is unknown.There is a clear need to investigate its pathogenesis which can offer potential therapeutic targets.Objective The aim of this study was to investigate the expression and distribution of visfatin and vascular endothelial growth factor (VEGF) in diabetic model rats.Methods This study was approved by Animal Ethic Committee of Inner Mongolia Medical University.Sixty SPF 8-week-old male SpragueDawley rats were randomized into the diabetic group and control group.The rats were housed under a condition that alternated between 12 hours of light and darkness,with free access to rat food and water.Diabetes was induced by intraperitoneal injection of 60 mg/kg (0.60 ml/100 g) of streptozotocin (STZ) and control rats received equivalent volume of buffer.The models were regarded as successful when blood glucose was ≥ 16.7 mmol/L.Rats were sacrificed 12 weeks after the injection of STZ and retinal specimens were prepared to detect the expression of visfatin and VEGF.Total retinal protein was isolated from the retinas of experimental and control eyes,and the expression of visfatin and VEGF was assessed by Western blot.Frozen cross sections of retinas of 5 μm thickness were used to perform double immunofluorescence staining with anti-visfatin and anti-VEGF antibodies.Results Mean body weight of the diabetic rats was (189.02±11.34) g and that of the control rats was (489.57 ± 14.48) g at 12 weeks post-injection,showing a significant difference between them (t =5.236,P =0.003).Mean blood glucose level was (29.25±3.86) mmol/L in the diabetic group and (5.32±1.01) mmol/L in the control group,demonstrating a significant difference (t =11.778,P =0.000).Double immunofluorescence staining showed reduced expression of visfatin and VEGF in the retinal nerve fibrous layer and glial cells in the control rats.A stronger staining for visfatin and VEGF was found in the various layers of the retina in the diabetic rats,with an expression level of visfatin (A value) of 346.26±41.23,which was considerably higher than that of the control group (102.07±65.01) (t =8.291,P =0.000) in 12 weeks after injection.Furthermore,the expression of VEGF in the retina was elevated in the diabetic group compared with the control group (A value) (415.88±92.15 vs.113.06±32.06) (t=10.067,P=0.000).Conclusions Visfatin might contribute to the pathologic progression of diabetic retinal,neovascularization and it might play a synergistic role with VEGF in the pathophysiology of DR.

Objective To evaluate the effect of various herniorraphy in treating inguinal hernia. Methods The clinical data of 108 patients who underwent conventional Bassini herniorraphy (BH), tension free herniorraphy (TH), or laparoscopic herniorraphy (LH),respectively were analysed and comparated. Results The operation time in TH was less than that in BH, and in LH was longer than that in TH. The ability recovery, hospita stay and postoperative complication in TH and LH were less than those in BH.All the patients were followed up for at least 1 year.Of them, 1 recurred after BH, but there was no recurrence after TH and LH. The blood neutrophils, serum level of fibrin, C-reactive protein and alpha-1 antitrypsin increased significantly in the patients undergoing herniorraphy, which were significantly higher in the patients underwent TH and LH. Conclusions The curative effect of TH and LH is much better than that of BH in treating ingumal hernia. Application of marlex for herniorraphy might increase inflammation response, but it will not increase the incidence of infection.

Objective To compare the effect of application of autologous iliac alone and NovaBone combined with autologous iliac in the acetabular osteotomy of children with developmental dislocation of the hip (DDH).Methods Data of 113 cases of children with DDH who had undergone open reduction and acetabular osteotomy surgery from 2007 to 2011 were retrospectively analyzed.According to bone material using after acetabular osteotomy,the patients were divided into autogenous iliac bone graft group (52 cases,60 hips) and NovaBone combined with autologous iliac bone graft group (61 cases,67 hips).There were no statistical differences in gender,age,side,dislocation type,osteotomy and acetabular index between the two groups.The patients were evaluated by Lane's scoring criteria,Severin standards and McKay standards at 6 weeks,3 months,6 months,1-year and 2-year post-operation follow-up.The bone healing of acetabular osteotomy zone,radiography and function of hip were compared.Results 6 weeks and 3 months after operation,Lane bone healing score in NovaBone combined with autologous iliac bone graft group (6.4±1.3 points and 9.6±1.7 points respectively) was obviously superior to autogenous iliac bone graft group (4.7±1.5 points and 7.8±1.2 points respectively).And 6 months and 1 year after operation,the two groups were basically reached bone healing.The Severin standard results showed that the rate (94％,63/67) of Excellent and Good in NovaBone combined with autologous iliac bone graft group (excellent:41 hips,good:22 hips,Fair:4 hips) was significantly higher than the rate (83.3％,50/60) in autogenous iliac bone graft group (excellent:28 hips,good:22 hips,Fair:10 hips).The rate (16.7％,10/60) of Fair in autogenous iliac bone graft group was significantly higher than the rate (6.0％,4/67) in NovaBone combined with autologous iliac bone graft group.McKay standard results were consistent with the results of radiological evaluation.Conclusion As a novel bone defect repair material,NovaBone can promote early bone healing process of acetabular osteotomy areas.It also can improve the resistance of osteotomy area.NovaBone can get a satisfied result in acetabular osteotomy in children with DDH.

Objective To study the characteristics of plasma adiponectin levels exhibiting in gestation women and newborns, as well as the relationships between adiponectin levels and fetal birth weight. Methods Totally 98 subjects have been considered in this study, in-cluding venous blood samples of 36 healthy non-pregnant women (control group), 31 uncomplicated pregnant women (pregnancies group) and the cord blood samples taken at delivery of their singleton infants born at term (newborns group). The concentrations of adiponectin and insulin were determined by radioimmunoassay technique. And SPSS was used for statistical analyses. Results The adiponectin level in women of late period of gestation (WLPG) (11.10±5.72)g/ml was lower than that of other two groups, and the newborns average cord plasma level of adiponectin was (30.71±12.77) g/ml significantly higher than that of the control group (16.52±6.87) g/ml. The adipone-ctin level for WLPG was correlated with FINS and HOMA-IR (r = -0.411, -0.393, P <0.05). The adiponectin level in cord plasma was positively correlated with birth weight(r = 0.416, P < 0.05). The adiponectin level in WLPG was correlated neither with the adiponec-tin level nor body weights of their newborns. Conclusions The average cord plasma adiponectin level of newboms is significantly higher than that of the control group and WLPG. It is positively correlated with birth weight, which suggests that adiponectin may be involved in reg-ulating fetal growth. The adiponectin level in WLPG is correlated neither with the adiponectin level nor body weights of their newborns.
