Objective The objective of this study was to investigate the role of sulindac in sensitization effects of NF-κB on apoptosis induced by TNF-α in human breast cancer.Methods The human breast cancer MCF-7 cell line was added sulindal in the logarithmic growth phase and the final concentrations of sulindac were 0.5 and 1.0 mmol/L.The cells in control group was cultured without adding succinic acid.After sulindac treatment for 48 h,flow cytometry,MTT and Western blotting were used to analyze the effect and mechanism of cell growth in MCF-7 cells.Results The inhibitory rate of cell proliferation was(29.17±1.23)% and(38.15±1.51)% in MCF-7 cells treated with 0.5 and 1.0 mmol/L of Sulindac for 48 h,respectively,when compared to the control group(1.15 ± 0.02)%(P<0.05).Compared with the control group,0.5 and 1.0 mmol/L of sulindac were significantly increased the G0/G1 phase in MCF-7 cells(P<0.05).The apoptosis rate of sulindac in MCF-7 cells was significantly higher than that in the control group(P<0.05).The expression levels of TNF-α were(2.09±0.67)% and(1.18±0.09)% in the concentrations of 0.5 and 1.0mmol/L sulindac,respectively,in MCF-7 cells when compared to the control group(7.42±0.56)%.Conclusion Sulindac has a certain effect on the growth of human breast cancer cells,which can promote the prolongation of cell cycle at the G0/G1 phase and improve sensitization of apoptosis.This mechanism may be related to the inhibition of TNF-α activity.

Objective To evaluate intra-biliary tunnel electro-resection and aspiration approach during ERCP for severe biliary stricture.MethodsA total of 14 patients with severe benign or malignant biliary stricture,which failed in previous ERCP,were recruited. First the guide wire was passed gently through the narrow segment under fluoroscopy,then the double-lumen needle knife was placed near the stricture and wire cutter was protruded.The tunnel electro-resection and aspiration was performed along the guide wire until the narrow segment could be passed through under fluoroscopy by the expanding balloon dilator for the following procedures.ResultsOf 14 patients with severe biliary strictnres,electro-resection and aspiration procedure were successful in 12 (85.7％).Metal stents were implanted in all 7 patients with malignant biliary strictures.Plastic stents were placed after balloon dilatation in 5 patients with benign stenosis.Three out of 5 patients received double plastic stents,while the two others only needed a single plastic stent.The procedure was failed in 2 patients ( 14.3％ ) with malignant biliary strictures as hilar cholangiocarcinoma invaded the left and right hepatic duct,forming a right angle in biliary stenosis,so that needle knife could not go through,and the following procedure was aborted.There were no severe complications like massive bleeding,perforation or death observed.ConclusionThe intra-biliary tunnel electro-resection and aspiration approach can significantly increase the success rate of ERCP in severe biliary strictures.

Objective To investigate the incidence of adverse pregnancy outcomes among women with syphilis in Zhejiang province during 2013-2014,and to explore the influence of anti?syphilis treatment on pregnancy outcomes. Methods A retrospective study was carried out according to the Information Management System for preventing mother?to?child transmission(PMTCT)of syphilis in Zhejiang province during 2013-2014. The incidence of adverse pregnancy outcomes was compared between women with syphilis and general women without syphilis, between treated and untreated women with syphilis, as well as between women with syphilis receiving and not receiving standard anti?syphilis treatment. The effects of anti?syphilis treatment and standard anti?syphilis treatment on pregnancy outcomes were analyzed. Results Data were collected from 3 985 women with syphilis and their children. Of these women, 12 had a stillbirth, and 3 973 a live birth. Totally, 3 210(80.55%)women received anti?syphilis treatment, 967(30.12%, 967/3 210) women received substandard treatment, and 775(19.45%)did not receive anti?syphilis treatment. Of the 3 985 fetuses or neonates born to women with syphilis, 45(1.13%)had abnormal clinical symptoms/signs. The incidence rates of low birth weight and early neonatal death were 7.00%(279/3 985) and 1.13%(45/3 985) respectively in fetuses or neonates born to women with syphilis, both significantly higher than those in fetuses or neonates born to general women without syphilis (3.18%[26 092/819494] and 0.13%[1 029/819 494], respectively, both P < 0.01). Among 775 untreated women with syphilis, the incidence rates of premature birth, low birth weight, early neonatal death, congenital syphilis and abnormal neonatal symptoms/signs were 15.61%(121/775), 10.84%(84/775), 2.45%(19/775), 3.48%(27/775)and 2.84%(22/775)respectively, all significantly higher than those in 3 210 women receiving anti?syphilis therapy (8.26%, 6.07%, 0.81%, 0.81% and 1.03%,respectively, all P < 0.01). Besides, the 967 women receiving substandard anti?syphilis treatment showed higher incidence rates of premature birth, low birth weight, early neonatal death, congenital syphilis and abnormal neonatal symptoms/signs than the 2 243 women receiving standard treatment (10.44%vs. 7.31%, 8.17%vs. 5.17%, 1.55%vs. 0.49%, 1.65%vs. 0.45%, 1.96%vs. 0.62%, respectively, all P<0.01). Conclusions The incidence of adverse pregnancy outcomes is high among women with syphilis in Zhejiang province during 2013-2014. Untreated and inadequately treated maternal syphilis is strongly associated with adverse pregnancy outcomes.

Ten pharmacophore models of beta-tubulin inhibitors were established from the training set of seventeen beta-tubulin inhibitors (two categories) with comformer analysis by using the Catalyst software. The optimal pharmacophore model with two hydrophobic units and two hydrogen bond acceptor units were confirmed (RMS = 0.43, Correl = 0.98, Weight = 2.06, Config = 15.97). This pharmacophore model is able to predict the activity of known beta-tubulin inhibitors and can be further used to identify structurally diverse compounds with higher activity.

Objeetive To explore the situation of rotavirus infection and extraintestinal organe damage in children in Yueqing city.Methods Two hundred and eighty-seven cases with acute rotavirus gastroenteritis in our hospital were analyzed for prospective study from October 2011 to January 2013 by stool tests.Results Rotavirus infection was found to be more common in autumn and winter.There were 223 cases (17.7％) got extraintestinal organe damage,175 cases (60.80％) got myocardial lesion,and 78 cases (27.18％) got respiratory infection.At the same time,there were 51 cases (17.77％) and 21 cases (7.31％) got liver function lesion and convulsion respectively.Among the metabolic acidosis(48 cases),39 cases were combined with myocardial lesion.While non metabolic acidosis were 239 cases (81.25％),and 136 cases were combined with myocardial lesion.Therefore,the myocardial lesion was significant correlation with metabolic acidosis (P ＜ 0.01).Iron deficiency anemia was 123 cases and combined with 15 cases (12.19％) convulsion,while the convulsion prevalence rates of non iron deficiency anemia was 6 cases (3.65 ％).There was a statistically significant difference between the convulsion prevalence rates of iron deficiency anemia and that of non iron deficiency anemia (P ＜ 0.01).Conclusion Rotavirus diarrhea can lead to extraintestinal organe damage,and the clinical doctors should pay attention to them.

Objective To investigate the efficacy of holmium laser coagulation under choledochoscope for the treatment of intrahepatic hemobilia.Methods The clinical data of 55 patients with intrahepatic hemobilia who received holmium laser coagulation under choledochoscope at the General Hospital of Chengdu Military Area from June 2003 to August 2011 were retrospectively analyzed.After the hemobilia was confirmed with choledochoscopy,an optical fiber of holmium laser was inserted into the intrahepatic bile duct from the hole of choledochoscope.The top of the optical fiber was posed close to the bleeding region,and then the laser was stimulated for coagulation under direct vision.If the observation of the bleeding area was influenced by the bleeding,the porta hepatis was temporarily occluded with a rubber hose combined with pressurized liquid injection bag.For patients with distal bile duct stenosis and bleeding,the narrow area was first expanded by biliary balloon or laser,then hemostasis was completed after the flow of bile duct was restored.Results The hemorrhage of the 55 patients was controlled,with an average time of 5.5 minutes (range,2-15 minutes).Temporary hepatic portal clamping was applied for 16 patients (27 times),and the average blocking time was 2.2 minutes (range,1-4 minutes).Biliary rehaemorrahagia occurred after operation in 2 patients,and they were cured by non-surgical treatment.All patients were discharged after successful hemostasis.The time of follow-up was 35-49 days.The epithelium of the bile duct coagulated by intraoperative holmium laser restored flat in 41 patients,and new biliary stricture was not found in the other 14 patients.Conclusion Holmium laser coagulation under choledochoscope for intrahepatic hemobilia is simple and effective.

Objective To investigate the efficacy and safety of perioperative use of different hemostatic drugs in elderly patients undergoing transurethral resection of the prostate (TURP).Methods A total of 480 elderly patients with benign prostatic hyperplasia (BPH) admitted to the Departments of Urology and Gerontology of our hospital from January 2010 to October 2014 were selected and randomly divided into 6 groups (n =80,each).Patients in all groups were given preoperative oral finasteride for 1 week,with each of the non-control groups receiving perioperative heamocoagulase agkistrodon,mangabeys hemocoagulase,reptilase,ethylenediamine diaceturate,or dicynone + paraaminomethyl benzoic acid (PAMBA).Intraoperative bleeding,perioperative hematocrit,hemoglobin change,continuous bladder irrigation time,adverse reactions and other clinical parameters were recorded.Results Operations went smoothly with all patients.Changes in perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time had significant differences between the control group and the groups treated with hemostatic drugs (all P＜0.05).No significant differences in perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time were found between groups treated with heamocoagulase agkistrodon,mangabeys hemocoagulase and reptilase,or between groups treated with ethylenediamine diaceturate and dicynone+PAMBA (all P＞ 0.05).There were significant differences in the perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time between the groups with and without blood coagulation enzymes (all P ＜0.05).Fibrinolytic responses occurred in 2 patients in the heamocoagulase agkistrodon group and were mitigated after drug withdrawal and fibrinogen infusion.Conclusions A reasonable perioperative dose of a hemostatic drug has good clinical effects in elderly patients undergoing TURP.Hemostatic drugs such as blood coagulation enzymes have certain advantages including safety over other types of hemostatic drugs,but their doses should not be too large.

Objective:This study aimed to investigate the relationships between anthropometric parameters and carotid elasticity by real-time vascular quantification stiffness technique (R-VQS), and to identify the predictive value of anthropometric parameters for cardiovascular disease risk.Methods:A total of 563 adults were recruited for this study and were divided into two groups by gender. The anthropometric indices [body mass index (BMI), waist circumference (WC), a body shape index (ABSI), body round index (BRI), and visceral adiposity index (VAI)] were calculated. R-VQS technique was used to assess the parameters of carotid elasticity: pulse wave velocity (PWV). The correlations between the anthropometric indices and PWV were analyzed. Linear regression was used to analyze the predictive factors of PWV.Results:⑴ The BMI, WC, ABSI, BRI, VAI and PWV were higher in men than those in women ( P<0.05); ⑵ In men and women, all the anthropometric parameters positively correlated with systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglycerides (TG), and negatively correlated with high-density lipoprotein (HDL) ( P<0.05); ⑶ diabetes mellitus (DM) and hypertension history were predictors of PWV in men ( β=0.110, 0.101, respectively, P<0.05); DM, hypertension history and smoking status were predictors of PWV in women ( β=0.061, 0.095, 0.067, respectively, P<0.05); ⑷ After adjusting for diabetes, hypertension and smoking, ABSI and VAI were predictors of PWV in men ( β=0.078, 0.068, P<0.05); BMI, WC, ABSI, BRI and VAI were predictive factors of carotid PWV in women ( β=0.131, 0.123, 0.204, 0.153, 0.196, P<0.05). Conclusions:Among the anthropometric indexes, ABSI and VAI have good correlations with carotid elasticity in wen and women, represented by PWV. These results suggest that ABSI and VAI may be convenient, highly cost-effective and simple parameters for obesity and are associated with cardiovascular disease (CVD) risk in clinical practice. R-VQS is a convenient, real-time and rapid technique for the early assessment of the carotid elasticity.

LPS stimulation of macrophages production of IFN-beta plays a key role in innate immunity defending the microbial invasion. In this study, the effect of S632A3 promoting LPS-induced IFN-beta production and the underlying mechanism were investigated, mRNA level was measured by real-time PCR, cytokine production was determined by ELISA, GSK-3beta activity was investigated by kinase assay, protein phosphorylation and expression were evaluated by Western blotting. The results revealed that S632A3 significantly augmented IFN-beta production by LPS-stimulated macrophages. S632A3 inhibition of the activation of GSK-3beta, reduced the threonine 239 phosphorylation of transcription factor c-Jun but increased the total level of c-Jun in LPS-stimulated macrophages. Moreover, small interfering RNA-mediated knockdown of c-Jun level abrogated the ability of S632A3 to augment IFN-beta. The study thus demonstrates S632A3 being a new anti-inflammation lead compound and provides a molecular mechanism by which S632A3 promoted LPS-induced IFN-beta production in macrophages through inhibiting the activation of GSK-3beta.
