Objective To investigate the therapeutic effect of combined administration of lactobacilli and clostridium butyricum on acute mice ulcerative colitis, and explore its therapeutic mechanism.Methods Dextran sulfate sodium (DSS)-induced mice model of acute ulcerative colitis was established. After administration of lactobacilli and clostridium butyricum, the pathological change of tunica mucosa coli was observed and the expression levels of tumor necorisis factor (TNF-α) and tissue factor (TF) were measured.Results Lactobacilli and clostridium butyricum significantly alleviated the damage of tunica mucosa coli and suppressed the expression of TNF-αand TF. By comparison, there were the lightest histological damage and the lowest expression of TNF-αand TF when lactobacilli and clostridium butyricum were administrated combined.Conclusion Both lactobacilli and clostridium butyricum show therapeutic effect on DSS-induced mice ulcerative colitis. The coordinate repression on expression of TNF-αand TF may be the molecular mechanism of the co-effect on mice UC.

Objective To evaluate the role of intravasc ular ultrasound (IVUS) in determining strategy for coronary artery stenosis of intermediate severity.Methods The study population consisted of 75 patients who had de novo coronary lesions of intermediate severity (40% to 70% diameter stenosis) in coronary angiography. IVUS examination was performed in all patients using standard methodology. Minimal lumen cross-sectional area (MLA) ≤ 4.0- mm 2 or percent area stenosis≥60% were identified as an IVUS index of functionally severe coronary stenosis, and used as an indication of coronary stenting. Major adverse cardiac events (cardiac death, acute myocardial infarction and recurrent angina) and the use of nitrates were recorded during follow-up. Results There were 44 patients (59%) with functional coronary artery stenosis, and all underwent successful coronary stenting. Acute coronary syndromes, soft plaque and positive coronary arterial remodeling were more common compared with the remaining 31 patients (41%) only treated medically. During a mean of (14?7) months of follow-up, there was no cardiac death and acute myocardial infarction. Readmission occurred in 5 patients (11%) due to in-stent restenosis in patients with interventional therapy and 4 patients (13%) due to exacerbation of coronary artery stenosis in patients with medical therapy. The use of nitrates was discontinued in 18(41%) and 14(45%) patients treated with interventional therapy and medical therapy, respectively. Conclusions It is valuable to perform IVUS examination in clinical decision making for intermediate coronary artery stenosis. IVUS criteria of MLA≤ 4.0- mm 2 or area stenosis≥60% may be a reliable index of functional coronary stenosis, determining the therapeutic strategy in patients with intermediate coronary artery stenosis.

Objective To investigate the role of c-Jun N-terminal kinase (JNK1/2) signaling pathway in enterovims 71 (EV71) infection.Methods The effects of different concentrations of SP600125 on the activity of human rhabdosarcoma (RD) cells were detected by trypanbalu staining.The levels of VP1 mRNA and protein in EV71-infected RD cells were detected by real time Q-PCR and western blot,respectively.The levels of total and phosphorylated JNK1/2,c-Fos and c-Jun protein were determined by western blot.Last,the effects of.JNK1/2 inhibitor SP600125 on EV71 replication and JNK1/2 signaling pathway were analyzed.Results The results of trypanbalu staining showed that 5 and 10 μmol/L of SP600125 didn't influence on the activity of RD cells (P ＞ 0.05),while 20 μmol/L of SP600125 decreased the survival of RD cells significantly (P ＜ 0.05).Compared with the control,the expression levels of VP1 mRNA and protein in EV71-infected RD cells decreased obviously at 8 hours post-infection (P ＜0.01).In addition,after RD cells were infected EV71,the levels of phosphorylated JNK1/2,c-Fos and c-Jun increased significantly (P ＜ 0.05).However,the pretreatment of SP600125 decreased the phosphorylation levels of JNK1/2,c-Fos and c-Jun protein obviously (P ＜ 0.05).Conclusion EV71 infection may effectively activate the JNK1/2 signaling pathway in RD cells,which may be related to EV71 replication.

Objective To evaluate the significance of color Doppler EUS in the pancreatic pseudo-cysts drainage. Methods EUS - guided cystoenterostomy was performed in 3 patients. A needle and drainage tube was inserted in a one - step procedure into the cyst through the accessory channel of echoendoscope under EUS. The nasal plastic drainage tube was released immediately after insertion. Results When gastric ulcer and bleeding or the bulge of stomach were not found endoscopically in all patients . The needle with its stylet inserted through the gastric wall into the cyst at the site with minimal distance between them . The mean size of the pseudocysts was approximately 8 cm located at pancreatic tail ,body or the junction of them. In 3 cases but one, the blood flow signal around the cyst was not found . No significant echo of laminated structure between gastric and cyst wall was found . After aspiration or installation of naso-cystic drainage catheter, abdominal pain remitted at 2 days, 2 days and 3 days; the sonography demonstrated that cyst size decreased began from 3rd day ,and the cyst obliterated at 14 and 30 days after drainage. The only complication was found in one patient with gastric mucosal ooze, which recovered after noradrenaline spray . Infection or perforation never occurred. No recurrence of pseudocysts observed at a mean follow - up period of 3. 6 months (range 2-7 months). Conclusions The EUS-guided drainage of pancreatic pseudocysts in one-step is a rather simple and practical procedure with minimal risk of hemorrhage and infection.

0.05).Multivariate analysis showed that the recurrence was related to the number and diameter of the tumors,with the hazard ratios being 1.877(P=0.001)and 1.391(P=0.029 4),respectively;injection of MMC had no influence on the recurrence.There was no significant difference in the time of disease-free survival(DFS)between the 2 groups,with the median time of DFS of MMC injection group being 5 months and of control group being 3 months after the first operation(P=0.125 3).The recurrence rates in the MMC group and control group were 65.79% vs 68.57%(P=0.800 4) 6 months after operation,81.58% vs 94.29%(P=0.099 0)1 year after operation,89.47% vs 97.14%(P=1.679 55) 2 years after operation and 92.11% vs 97.14%(P=0.344 7)3 years after operation.Conclusion: Injection of 10mg MMC via great omentum vein during resection of IHCC may have no definite effect on the recurrence of IHCC;however,perspective study is needed to verify this finding.

Objective To evaluate the clinical efficacy of coroflex (BRAUN, Germany) intracoronary stent. Methods To retrospectively analyze the immediate angiographic and clinical follow-up outcomes of 81 patients (pts) receiving coroflex intracoronary stenting. Results 88 coroflex intracoronary stents were implanted in 81 pts. According to ACC/AHA classification, 38 lesions were type A-B 1, 50 lesions were type B 2-C. 52 lesions were de novo, 22 were suboptimal results after PTCA and 14 lesions were bailout for dissections. Stent deployment was successful in 82/88 (93.2%). High-pressure (16-18 atm) balloon was used for stent deployment in 3 lesions with severe calcification. Dissection was occurred at distal of stent in 2 lesions but no inducing flow reduction. Angiography showed TIMI 2 grade after intracoronary stenting in 1 diffused lesion. There were no adverse events occurred during hospital stay. Clinical follow-up of in 75 pts were conducted for 7.5?3.0 (3-13) months, there were no cardiac death or myocardial infarction reported. Complain of angina (CCS class Ⅰ) occurred in 17 pts (22.7%). Repeat angiography was performed in 7 pts, there were 2 in-stent restenosis with successful revascularization. Conclusion Coroflex intracoronary stenting appears to be safe and effective in the treatment of coronary lesions with favorable outcomes.
