Objective To observe the clinical effect of different doses of simethicone on the colonoscopy bowel preparation.Methods One hundred and fifty outpatients who received colonoscopy were randomly divided into three groups:group A1 (PEG plus 5 ml simethicone),group A2 (PEG plus 10 ml simethicone) and group B (PEG =polyethylene glycol electrolyte).The colonic cleaness,effect of removing bubbles,total procedure time,patients' satisfaction and tolerance were observed during the examination.Results The satisfaction with bubbles removal were 98.0％ (49/50),100.0％ (50/50) and 80.0％ (40/50) with significant difference(x2 =17.855,P =0.000).However,there was no difference in cleaness (x2 =1.500,P =0.472),total procedure time (Z =-0.333,P =0.765),patients' satisfaction (x2 =6.303,P =0.178) and tolerance (x2 =8.238,P =0.083).Conclusion Simethicone is of benefit for colonoscopic bowel preparation in removing air bubbles,which can enhance visibility.Five ml dose of simethicone can meet the basic need of removing air bubbles,and 10 ml dose of simethicone can exert better effects.

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.

Objective To compare the differences between antrum and corpus in endoscopic and histological diagnosis in non-ulcer dyspeptic patients.Methods 132 cases from out-patient department who had been ordered to undergo gastroendoscopy for dyspepsia were enrolled in the study.After endoscopy,different signs including redness,erosion,intramural bleeding and rugal atrophy were described.Histological diagnosis was defined according to the classification of chronic inflammation,polymorphonuclear neutrophil activity,glandular atrophy,intestinal metaplasia,helicobacter pylori and dysplasia.The differences between antrum and corpus in endoscopic and histological diagnosis were analyzed.Results Redness and erosion under endoscopy,glandular atrophy and chronic inflammation in histological diagnosis were found more frequently in antrum than in corpus.P values were less than 0.001,0.01,0.001 and equaled to 0.025 respectively.Conclusion In functional dyspeptic patients,there are differences in the endoscopic and histological findings between antrum and corpus.Redness and erosion in endoscopic diagnosis,glandular atrophy and chronic inflammation in histological diagnosis are more common in antrum when compared with that in corpus.

Objective To explore the safety and efficacy of endoscopic retrograde cholangiopancreatography(ERCP)by using carbon dioxide for malignant biliary obstruction.Methods A total of 60 patients with malignant biliary obstruction, hospitalized from September 2008 to February 2010, were randomly divided into 3 groups to receive ERCP by using carbon dioxide, contrast agent or magnetic resonance cholangiopancreatography(MRCP)without any agent.The safety and efficacy of 3 contrast methods were compared.Results Successful stent or drainage tube insertion was achieved in all patients.Carbon dioxide was superior to contrast agent in terms of lowering postoperative infection rate(P ＜ 0.05), and it was also superior to MRCP for more effective drainage(P ＜ 0.05).There was no significant difference in occurrence of postoperative pancreatitis and hyperamylasemia between 3 groups.Conclusion Using carbon dioxide during ERCP, safe and effective, is superior to use of contrast agent in less leukocyte increase, and to MRCP in more adequate drainage in patients with malignant biliary obstruction.Furthermore, there is no more risk of pancreatitis and hyperamylasemia.

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.

For observation of the therapeutic effect of some foods on hyperlipi-demia in men, study was perfomed with subjects of hyperlipidemia by using mushroom, soya bean meat, beans, garlic, spring onions, prawn, chives, walnut seeds, peanut seeds, fishes etc. After 3 months treatment, the average values of serum total cholesterol and triglyceride were decreased significantly. The percentage of serum high-density lipoprotein cholesterol in the total cholesterol was increased from 24.7% to 31.3%; the percentage of serum low-density lipoprotein cholesterol was decreased from 61.8% to 49.2%. The curative rates of subjects with hypercholesterolemia were 93.3%, and the subjects with hypertriglyceridemia were only 50.0% and 57.1%. The effective rates were 79-87%.

Objective To investigate the clinical effects of Kangfuxin Solution used together with Baofukangshuan on chronic cervicitis after having been processed cervical LEEP circumcision.Methods Retrospective analysis was made among 176 out-patients diagnosed of chronic cervicitis from November 2007 to January 2009.Of all these patients,90 patients were treated with Kangfuxin Solution and Baofukangshuan after LEEP circumcision(the treatment group),and 86 patients were treated with simple cervical LEEP circumcision(the control group).The wound healing,vaginal discharge,bleeding volume,and side effects were observed in both groups.Results The method in the treatment group significantly reduced the amount of vaginal discharge and the duration,decreased the amount of bleeding and the duration;excluded wound infection and adverse reactions,and facilitated cervical wound recovery.The curative rate(98.89%)in the treatment group was significantly higher as compared to the control group(86.05%)after 8 weeks of the treatment.Conclusion Cervical LEEP circumcision surgery supplemented by Kangfuxin solution and Baofukangshuan therapy has better efficiency than treated by simple cervical LEEP circumcision.
