Objective To evaluate the effect of anisodamine on expression of Toll-like receptor 4 (TLR4) in the kidneys of exhausted rats.Methods Forty-eight male SD rats weighing 200-220 g were randomly divided into 3 groups:control group (group Ⅰ ) (.n =8) ; exhaustion group (group Ⅱ ) ( n =24) and anisodamine group (gronp Ⅲ) (n =16).In groups Ⅱ and Ⅲ exhaustion was induced by exhausting swimming and defined by (1) the animal sank to the bottom and stayed for＞ 10 s during swimming,(2) uncoordinated swimming,and (3) the animal lost escape/righting reflex when placed on the table In group Ⅲ intraperitoneal anisodamine 10 mg/kg was administered at 20 min before swimming.The animals were sacrificed immediately (T1 ),6 h (T2 ) and 24 h (T3 ) after exhaustion respectively.Their kidneys were obtained for detection of apoptosis and determination of TLR4 protein (by immuno-histochemical staining) and mRNA (by RT-PCR).Results Exhaustion significantly increased the number of apoptotic cells and up-regulated TLR4 protein and mRNA expression in group Ⅱ as compared with group Ⅰ,and anisodamine significantly attenuated the exhaustion-induced increase in the number of apoptotic cells and up-regulation of TLR4 protein and mRNA expression in group Ⅲ as compared with group Ⅱ.Conclusion Anisodamine can decrease apoptosis in renal cells in exhausted rats bydown-regulating TLR4 expression.

Clinical data of 83 patients with obscure gastrointestinal bleeding (OGIB) undergoing capsule endoscopy were reviewed retrospectively.The results showed that the overall detection rate of gastrointestinal lesions for OGIB by capsule endoscopy was 81.9％ (68/83), most lesions (77. 1％, 64/83 )were located in small intestine. Of all the small intestinal lesions, arteriovenous malformation (AVM) was the most common (22 cases, 26.5％ ),followed by small intestinal space-occupying lesion (18 cases,21.7％ ) and single or multiple ulcers of small intestine ( 16 cases, 19. 3％ ). Four cases (4. 8％ ) had lesions outside of the small intestine. Small intestinal AVM was the leading cause of OGIB in patients ＞ 50 y,space-occupying lesion was the most common in patients aged 30 -50 y, while ulcer was the leading cause in patients ＜ 30 y. Bowel obstruction was not found in this group of patients. The results indicate that capsule endoscopy has great diagnostic value in detecting causes of OGIB. Small intestinal AVM is the most common cause of OGIB, followed by space-occupying lesion and ulcer.

Objective To compare the transurenthral resection to radical cystectomy on muscle invasive bladder cancer, and to explore the factors affecting the prognosis. Methods Data of 74 patients with muscle invasive bladder can?cer were retrospectively analyzed. There were 38 cases underwent radical cystectomy (group A), and were treated with intra?venous chemotherapy after operation. There were 36 cases underwent transurenthral resection (group B), and were treated with intravenous and urinary bladder irrigation chemotherapy. All patients were followed up 61 (5-91) months. Data were compared between two groups including duration of surgery, intraoperative blood loss, the cumulative length of hospital stay, cancer recurrence rate and 5-year survival rate . The factors may affecting the prognosis in patients were collected and ana?lyzed by the Log-rank univariate and Cox multivariate analyzed. Results The values of operation time, intraoperative blood loss and the cumulative length of hospital stay were significantly lower in group B than those of group A ( P<0.01). There were no significant differences in cancer recurrence rate and 5-year survival rate between two groups (P>0.05). Results of the Log-rank univariate analysis showed that the tumor size≥5 cm and T3 stage were the important factors of 5-year relapse-free survival rate and 5-year overall survival rate. Results of the Cox multivariate analysis showed that the tumor size≥5 cm (RR=3.687, 95%CI:1.913-7.105, P<0.001) was the important factor of recurrence in patients after operation. T3 stage (RR=3.325, 95%CI:1.437-7.695, P=0.005) and tumor size≥5 cm (RR=5.017, 95%CI:2.440-10.317, P=0.002) were the risk fac?tors of the 5-year overall survival rate. Conclusion The transurenthral resection with intravenous and urinary bladder irri?gation chemotherapy deserves recommendation for the treatment of muscle invasive bladder cancer. Tumor size ≥5 cm and T3 stage are the important factors for the prognosis.

Objective To explore the effect of Buyanghuanwu decoction on blood glucose control and renal function protection in patients with early diabetic nephropathy.Methods 170 cases of patients with early diabetic nephropathy from May 2012 to June 2013 in wenzhou hospital of integrated traditional chinese and western medicine were selected,all patients were divided into observation group and control group,the control group was given routine treatment,the observation group treatment with Buyanghuanwu decoction based on control group .The clinical effective rate was compared between the two groups after treatment,the levels of blood lipids, 24 h urine microalbumin and hemorheology were compared between the two groups before and after treatment.Results After treatment, the total effective rate of the observation group was 90.59%,which was significantly higher than the control group 76.47% (P<0.05).Compared with before treatment,the levels of triglycerides and cholesterol decreased in two groups,high-density lipoprotein levels increased,24 h urine microalbumin decreased,whole blood viscosity,whole blood viscosity trimming and fibrinogen decreased,the difference was statistically significant(P<0.05).Compared with the control group,the levels of triglycerides and cholesterol in observation group was lower,high-density lipoprotein was higher,24 h urine microalbumin was lower,whole blood viscosity,whole blood viscosity trimming and fibrinogen were lower,the difference was statistically significant(P<0.05).Conclusion Buyanghuanwu decoction in the treatment of diabetic nephropathy is effective in treating diabetic nephropathy,it can effectively reduce blood lipids and blood viscosity,significantly reduce urinary protein excretion and protect the kidneys.

Objective To investigate the relationship between serum nesfatin-1 and gestational diabetes mellitus (GDM). Methods The serum nesfatin-1 concentrations were measured in 45 GDM patients and 44 NGT pregnant women , as well as 47 non-pregnant healthy women served as control. Serum nesfatin-1 were measured by sandwich enzyme linked immunosorbent assay (ELISA). Meanwhile FPG、 lipoid、 FFA、 FINS、 C-tide were also measured. Result Serum nesfatin-1 level in GDM were significantly higher in GDM patients than in NGT and control (P < 0.01), while serum nesfatin-1 in NGT was significantly lower than in control (P < 0.01). Correlation analysis showed that serum nesfatin-1 was positively correlated with FINS , C-tide , HOMA-IR , triglycerides FBG and OGTT 1 hour glucose, HbA1c (P < 0.05). Conclusion Serum nesfatin-1 level in pregnant women significantly decreas, while in GDM patients significantly increase. Serum nesfatin-1 level in pregnant women is positively correlated with Insulin resistance (IR) and triglycerides level.
