Objective To study the effects of three kinds of endoscopic therapy on gastric varices. Methods In this study, the efficacies of endoscopic band ligation ( EVL) , endoscopic injection of tissue adhesives (histoacryl) and sclerotic agent (EIS) for gastric varices were assessed. Forty consecutive, non-randomized patients with gastric varices were prospectively studied. EVL was done for 11 cases, Histoacryl 15 cases, and EIS 14 cases, to control and prevent relapse of bleeding. Results In the following-up ( six months) period, the effective rate of EVL, histoacryl and EIS were 100. 0% , 100. 0% and 72. 7% ; the e-radicative rate 25. 0% , 30. 8% ,0 (P

Objective To investigate the effects of Arctigenin ( ATG ) on concanavalin ( ConA )-stimulated cell proliferation and cytokine secretion in mouse spleen cells, and its possible mechanism. Methods The toxicity of ATG on mouse spleen cells was determined by MTT assay. The inhibition of proliferation was investigated by tritiat-ed thymidine incorporation method. Secreted cytokines (IFN-γand IL-2) were analyzed by ELISA. The associated proteins and phosphorylation levels of mTOR pathway ( mTOR/P70 S6 K/Akt/AMPK/Raptor ) were detected by Western blot. Results ATG had no significant toxicity to mouse spleen cells. ATG significantly inhibited mouse primary spleen cells proliferation induced by ConA. ATG suppressed IL-2 and IFN-γ production of mouse spleen cells in a concentration-dependent manner. ATG remarkably suppressed the phosphorylation of mTOR and P70S6K, and enhanced the phosphorylation of upstream AMPK and Raptor, while the phosphorylation of Akt did not change significantly. Conclusion ATG markedly suppresses the proliferation of mouse spleen stimulated by ConA cells and secretion of IFN-γand IL-2 , which may be correlated to the abilities of enhancing the phosphoryla-tion of AMPK and Raptor, inhibiting the phosphorylation of mTOR and P70S6K.

In order to evaluate the effect of multimedia-assisted teaching on stomatology courses and find out the appropriate teaching methods for non-stomatology medical students,we investigated the distribution of examination scores,diagnostic accuracy of ordinary diseases and accuracy of problem-based learning(PBL) results of multimedia-assisted teaching and traditional teaching means.The examination scores were closer to standard distribution,and the diagnostic and PBL results accuracy increased among students with multimedia-assisted teaching.Compared with traditional teaching means,multimedia-assisted teaching may improve the teaching quality in non-stomatology medical courses.

Objective To compare the anti-hemorrhage effect and safety of hemocoagulase and epinephrine (1∶10 000) during endoscopic mucosal resection (EMR) or polyps electrocautery. Methods Between April and November 2007,totally 60 patients received EMR or endoscopic piecemeal mucosal resection (EPMR) in our hospital because of local lesions in the esophagus,stomach or colon. The patients were randomly divided into hemocoagulase and epinephrine groups (30 cases in each) before receiving the operation. After the resection,the hemorrhage at the surgical area was measured. During the operation,the blood pressure,heart rate,and adverse effects including palpitation,dizziness,pain,and nausea were recorded. Results Immediate hemorrhage was detected in 1 case of hemocoagulase group (1/30,3%),and 6 cases of epinephrine group (6/30,20%,?2=2.588,P=0.108). No hemorrhage was observed at 24 hours in both the groups. No significantly difference was noticed in the injection volume between the two groups [(11.0?6.0) ml (5-30 ml) in hemocoagulase group vs. (11.9?7.0) ml (5-28 ml); t=-0.535,P=0.595]. In epinephrine group,the mean artery blood pressure and heart rate increased significantly after the injection [(96.9?7.9) mm Hg vs. (99.9?8.1) mm Hg,t=-3.005,P=0.005; 79.8?7.9/min vs. 84.3?8.1/min,t=-3.585,P=0.001]. Whereas,no such differences were noticed in hemocoagulase group. Five cases in epinephrine group showed transient dizziness and palpitation,and 2 patients who had esophageal lesions complained of pain at the injection site. None of the hemocoagulase group had postoperative complications. Conclusions Hemocoagulase shows same anti-hemorrhage effect as epinephrine during EMR without leading to adverse effect.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective To study the independent risk factors of early rebleeding after endoscopic variceal ligation (EVL) and/or endoscopic injection of fibrin tissue adhesive.Methods Data of 370 patients who had cirrhosis and accepted 396 procedures of EVL and/or endoscopic injection of fibrin tissue adhesive were retrospectively studied.Independent risk factors for early rebleeding were determined by Logistic regression analysis.Results Results of all the factors that were significantly different between the re-bleeding and non-rebleeding patients,the portal vein diameter,ascites volume,Child-Pugh score and serum albumin were independent ones of early rebleeding after EVL and/or endoscopic injection of fibrin tissue adhesive ( P ＜ 0.05).Larger volume of ascites,wider portal vein diameter,reduced albumin,Child-Pugh score greater than 10 were indicative factors of rebleeding.Conclusion The early rebleeding rate after EVL and/or endoscopic injection of fibrin tissue adhesive is determined by portal vein diameter,ascites volume,ChildPugh score,and serum albumin.

Objective To assess the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for pancreaticobiliary diseases in children. Methods Data of 9 patients younger than 14 years who underwent ERCP at between November 2004 and May 2010 were indentified through a computer database search. Therapeutic methods, success rate and procedure-related complications were evaluated.Results A total of 9 patients underwent 17 ERCP procedures under anesthesia, including 16 therapeutic and 1 diagnostic procedure. The success rate was 94. 1% (16/17) and the complication rate was 11.8%(2/17), including 1 mild pancreatitis and 1 peri-pancreatic infection. Conclusion ERCP is an important tool with high safety and efficacy for diagnosis and treatment of pancreaticobiliary diseases in children.

Objective To evaluate the value of double stapling technique with curved cutter stapler in colorectal anastomosis,especially in low colorectal anastomosis. Methods The clinical data of 168 cases of rectal carcinomas treated with double stapling technique with curved cutter stapler were retrospectively reviewed.The intraoperative condition,postoperative complications and findings during follow up were analysed. Results During the operations,the processes of closure and anastomosis of all the patients were satisfactory,and no operative death occurred.After the operations,4 cases(2.4%) had anastomotic leakage,3 cases(1.8%) had anastomotic bleeding,and 2 cases(1.2%) had rectovaginal fistula.All the complications were cured.There was no anastomotic stricture. Conclusion Double stapling technique with curved cutter stapler may help to accomplish low colorectal anastomosis which is a difficult task for handed suture.
