Objective To investigate the effects of basic fibroblast growth factor(bFGF)and sucralfate on healing of experimental gastic ulcer in rats. Methods Thirty-two famale Sprage-Dawley rats were divide into 4 groups,averagely.bFGF 100 ng?100 g -1 ?d -1 , sucralfate 40 mg?100 g -1 ?d -1 , bFGF 100 ng?100 g -1 ?d -1 + sucralfate 40 mg?100 g -1 ?d -1 and normal saline were used in experimental gastric ulcer rats induced by acetic acid for 21 days. Contents of gastric acid and pepsin were measured,and the healing rate and quality of gastric ulcer and the number of capillaries in ulcer bed were evaluated. Results The amount of gastric acid and pepsin in bFGF group had no different from those of normal saline group. The ulcer areas in bFGF group and sucralfate group were (2.9 ?0.8) mm 2 and (3.2?1.2) mm 2 respectively,which were significantly smaller than that of normal saline group (6.8? 1.4 ) mm 2, P

Objective To study the safety and efficacy of endoscopic sphincterotomy (EST) and endoscopic papillary balloon dilation (EPBD) in the treatment for extrahepatic bile duct stones.Methods A total of 164 patients underwent endoscopic treatment for extrahepatic bile duct stones.Seventy eight underwent EST and EPBD (the EST + EPBD group),86 others underwent EST only (the EST group).The complication rate,complete stone clearance rate and gravel incidence rate were compared between the two groups.Results Hyperamylasemia occurred in 3 cases,mild acute pancreatitis in 2 cases of the EST and EPBD group,while hyperamylasemia occurred in 5 cases,mild acute pancreatitis in 3 and hemorrhage in 2 of the EST group.There were no severe complications like severe acute pancreatitis or intestinal perforation.The complication rate of the EST + EPBD group ( 6.4％,5/78 ) was slightly lower than that of the EST group ( 11.6％,10/86),(x2 =1.340,P =0.288),so was gravel incidence (33.3％ vs.60.5％,x2 =12.073,P =0.001 ).While complete stone clearance rate of this group was obviously higher than that of the EST group (100.0％ vs.93.0％ ),(x2 =5.649,P=0.030).Conclusion EST combined with EPBD is safe and effective for extrahepatic bile duct stone removal,especially for large stones or poor duodenal papilla.

Objectives To investigate the clinical characteristics and the regularity of seasonal changes that influence peptic ulcer (PU) in Nanehang area and to provide a theoretical basis for the treatment and prevention of PU.Methods Data collected from patients with PU diagnosed by clinic and gastroendoseopy between October 2003 to May 2008 were retrospectively analyzed.The PU was further divided into gastric ulcer,duodenal ulcer and complex ulcer.The lesion of gastric ulcer was calculated by five locations that were antral,angular,corporal,pyloric canal,fundic and cardia.The lesion of duodenal ulcer was calculated by five locations that were anterior wall of bulb,posterior wall,lesser curvature, greater curvature and postbulbar.The climate changes that influnced the incidence of PU disease were also observed.The detective rates of different types of PU were analyzed and its association with gender,age, lesion locations,seasons,Helicobacter pylori (Hp) infection and complications were also investigated. Results Among 83 888 patients who underwent endoscopy,PU was found in 21 308 patients (25.4%) including 66.33% duodenal ulcer,24.88% gastric ulcer and 8.79% complex ulcer.The male and femal ratio was 2.44 : 1 in PU,2.53 : 1 in duodenal ulcer,2.26 : 1 in gastric ulcer,and 2.33 : 1 in complex ulcer.The average age of patients with gastric ulcer was 48.0 years that was about 6.7 years higher than that of patients with duodenal ulcer.The prevalence of duodenal ulcer and gastric ulcer peaked in the 30- 39 years and 50-59 years,respectively.PU was more common from December to February (30.17%) and less common from June to August (22.54%) (P＜0.01) .The 57.43% of duodenal ulcer was found on anterior wall of bulb,18.26% on greater curvature,13.21% on lesser curvature,7.34% on posterior wall and 3.76% on postbulbar.The 45.69% of gastric ulcer was found on antral,20.54% on angular, 15.54% on corporal,9.36% on pyloric canal,and 8.87% on fundic and cardia.The 91.83% (12 318/ 13 414) of patients were positive for Hp infection.There was no significant difference of Hp infection among patients with different types of PU.The complications in patients with PU were bleeding (4.94%),pyloric obstruction (3.51%) and chronic perforation(0.04%).Conclusions The detective rate of PU in Nanchang area is 25.4%,which is higher than that in northern area of China.The incidence of PU is highly associated with sex,age,seasons and ulcer locations,with high Hp infections and a low incidence of complications.

Objective To investigate the clinical features of gastric stump ulcer (GSU)after partial gastrectomy due to gastroduodenal ulcer.Methods From January 1st 2007 to October 31th 2013,272 patients with partial gastrectomy for gastroduodenal ulcer underwent gastroscopy due to upper gastrointestinal symptoms were collected.Among them,there were 237 male patients and 35 female patients with the average age (55 .4 ± 13.0 )years.The lesion location,symptoms and pathological changes of GSU were analyzed.Chi-square test and Fisher exact probability analysis were used for count data comparison.The t test was performed for measurement data comparison.Results There was no significant difference between patients with GSU after Billroth Ⅰ gastrectomy and Billroth Ⅱ gastrectomy in the incidence of dysphagia,nausea and vomiting,retrosternal pain,retrosternal buring sensation,upper abdominal pain, abdominal distention, acid regurgitation and (or) epigastric buring sensation, hematemesis and (or)melena (all P >0.05 ).The proportion of ulcer located in remnant stomach and anastomotic stoma of patients with Billroth Ⅰ gastrectomy (24.7%,18/73 and 72.6%,53/73 )was higher than those of patients with Billroth Ⅱ gastrectomy (10.1 %,20/199 and 58.3%,116/199 )and the difference was statistically significant (OR=2.929 and 1 .896,95 %CI :1 .448 to 5 .927 and 1 .055 to 3.409,χ2 =9.482 and 4.649,P =0.002 and 0.031 ).There was no significant difference between the proportion of afferent loop and efferent loop ulcer in patients with Billroth Ⅱ gastrectomy and the proportion of duodenal ulcer in patients with Billroth Ⅰ gastrectomy (P =0.619).The diameter of GSU of patients with BillrothⅠ((1.1±0.7)cm)was larger than that of ulcer of patients with BillrothⅡ((0.8±0.6)cm) and the difference was statistically significant (t = 3.591 ,P = 0.007 ).The incidence of intestinal metaplasia and atypic hyperplasia of GSU was 8.1 % (22/272),and there was no significant difference in gastric ulcer,stoma ulcer,nek ulcer,afferent loop and efferent loop ulcer (all P >0.05).The incidence of gastric stump cancer of GSU was 4.0% (11/272)and that of gastric ulcer,stoma ulcer,nek ulcer,afferent loop and efferent loop ulcer was 13.2% (5/38 ),2.4% (4/169 ),1.8% (1/55 )and 1/10,respectively.The incidence of gastric stump cancer of gastric ulcer was significantly higher than that of stoma ulcer and nek ulcer, the differences were statistically significant (OR =6.250 and 8.182,95%CI :1.593 to 24.519 and 0.915 to 73.126,χ2 =8.687 and 4.788,P =0.012 and 0.040).There was no statistically significant difference in the incidence of gastric stump cancer of GSU in other gastric parts (all P > 0.05 ).There was no statistically significant difference in the incidence of intestinal metaplasia,atypic hyperplasia and gastric stump cancer between case with BillrothⅠgastrectomy and case with Billroth Ⅱ gastrectomy (P =0.650 and 0.733).Among the 11 gastric stump cancers,the number of cases with the onset time with 20 years,20-30 years and beyond 30 years after gastrectomy were one,three,seven,respectively.Conclusion The incidence of intestinal metaplasia, atypic hyperplasia and gastric stump cancer of patients with GSU was high,and the predilection site of GSU was the remnant stomach.

Objective To evaluate the safety of endoscopic retrograde cholangiopancreatography (ERCP) for elder patients (age more than or equal to 80 years).Methods Data of 464 patients (age ≥ 80 years) who underwent ERCP procedures from June 2008 to June 2014 in the First Affiliated Hospital of Nanchang University were compared with those of patients less than or equal to 60 years old,randomly chosen at 1∶4,for comorbidity,feature of disease distribution,intraoperative situation and postoperative complications of ERCP.Results The comorbidity rates of coronary heart disease,hypertension,chronic pulmonary disease and type 2 diabetes in observation group were significantly higher than those in the control group(P＜0.05),but there was no significant difference between two groups regarding to the comorbidity rate of arrhythmia(P =0.111).The main feature of disease distribution in two groups was choledocholithiasis,but the rate of malignant tumor in observation group was higher than that in the control group(P＜0.05).The success rate of ERCP showed no significant difference in two groups (98.92％ VS 99.35％,P=0.358).There was no significant difference between the two groups in the complication rates of acute pancreatitis (4.96％ VS 3.18％,P =0.064),infection (0.43％ VS 0.54％,P =1.000) and hemorrhage (1.08％ VS 0.59％,P=0.259).However the rate of perforation in observation group was lower than that in the control group (0.43％ VS 0.05％,P =0.043).Conclusion ERCP is safe and effective for elder patients.

Objective To compare the difference of the effects and safety of endoscopic submucosal dissection (ESD) and surgery for early gastric cancer. Methods We searched the Pubmed, CBM, Embase, Cochrane Library, CNKI, CQVIP and WanFang data from January 1990 to June 2016 studies comparing endoscopic resection with gastrectomy for treatment of early gastric cancer. We selected the eligible studies according the including and excluding criteria. The quality of the included studies was assess using the Newcastle-Ottawa Scale (NOS), then using Revman 5.3 to make the Meta analysis. Result The meta-analysis enrolled 12 studies with 4331 patients, all of the studies were retrospectively analyzed. The result of the meta-analysis showed that there were no significant difference regarding the recurrence rate [(22/2586, 0.85%) vs (6/1134, 0.53%), P = 0.370] and five-year survival rate [(852/909, 93.72%) vs (707/746, 94.77%), P = 0.340] between endoscopic resection and gastrectomy. Gastrectomy was associated with higher en bloc resection rate, which were 100.00% and 92.23% respectively. However, gastrectomy was also related to longer operative time (SMD = -3.04, 95%CI: -3.64 ~ -2.45, P = 0.000) and hospital stay (SMD = -2.53, 95%CI: -3.73 ~ -1.32, P = 0.000). The postoperative complication was also higher than endoscopic, which were (45/816, 5.50%) vs (101/686, 14.72%) respectively. Conclusion There were no significant difference regarding recurrence rate and five-year survival rate between endoscopic and gastrectomy. While the en bloc resection rate was lower than gastrectomy, endoscopic offers a shorter hospital stay, shorter operative time with minimal invasive and fewer operating and postoperative complications than gastrectomy. Endoscopic should be recommended as a standard treatment for early gastric cancer with indications.

Objective To evaluate the safety of anesthesia endoscopic retrograde cholangio pancreatography (ERCP) under general anesthesia.Methods From January 1st,2008 to June 30th,2016,patients underwent ERCP under general anesthesia were enrolled as anesthesia group and from January 1st,2005 to December 31st,2007,patients accepted ERCP without anesthesia were enrolled as control group.Chi-square test was performed to analyze disease composition,conditions during operation,success rate of operation and complications in these two groups.Results A total of 14 724 patients with ERCP under general anesthesia and 2 102 patients received ERCP without anesthesia were enrolled.In 14 724 patients with ERCP under general anesthesia,1 799 cases had malignant biliary and pancreatic diseases and 12 925 cases with biliary and pancreatic diseases.During the operation,transient hypoxemia occurred in 441 cases (3.00％) and relieved by increasing oxygen flow,lower anesthetic dose or lifting lower jaw.The success rate of ERCP in the anesthesia group (98.41 ％,14 490/14 724) was higher than that in the control group (97.34％,2 046/2 102),and the difference was statistically significant (x2 =11.500,P=0.001).The incidence rate of post-ERCP pancreatitis in the anesthesia group was 2.35％ (346/14 724),which was lower than that in the control group (3.85％,81/2 102),and the difference was statistically significant (x2 =16.813,P＜0.01).Conclusion ERCP under general anesthesia is safe,which could increase the success rate of operation and reduce the incidence rate of post-ERCP pancreatitis.

Objective To observe the efficacy and safety of endoscopic variceal ligation (EVL) and esophageal variceal sclerotherapy (EVS) with different hardeners for esophageal variceal bleeding (EVB).Methods Clinical data of 314 patients with EVB were retrospectively reviewed.The patients were divided into 5 groups according to the endoscopic treatments they have received,i.e.,endoscopic variceal ligation (EVL) group (n =112),sodium morrhuate sclerotherapy (EVS1) group (n =48),lauromacrogol sclerotherapy (EVS2) group (n =40),EVL plus sodium morrhuate sclerotherapy (EVLS1) group (n =26) and EVL plus lauromacrogol sclerotherapy (EVLS2) group (n =88).The efficacy,variceal recurrence rate and complication rate were evaluated.Results There was no significant difference in efficacy of stop bleeding among 5 groups,which was 85.7％ (96/112) in EVL group,83.3％ (40/48) in EVS1 group,92.5％(37/40) in EVS2 group,92.3％ (24/26) in EVLS1 group and 94.3％ (83/88) in EVLS2 group (P ＞0.05).The complete cure rates in EVLS1 group (88.5％,23/26) and EVLS2 group (87.5％,77/88)were significantly higher than those in 3 other groups (P ＜ 0.05).Rebleeding rates in EVS1 group (18.8％,9/48) and EVL group (11.6％,13/112) were significantly higher than those in other 3 groups (P ＜0.05).The patients were followed up for 6-18 months,and the varices recurrence rate was highest in group EVL (23.2％,26/112) and lowest in EVLS2 (10.2％,9/88,P ＜0.05).The complication rate in group EVS1 (32.2％,49/152) was significantly higher than that in other 4 groups (P ＜0.05).Conclusion EVL plus EVS,either with sodium morrhuate or lauromacrogol EVS is safe and effective for EVB,especially EVL plus Lauromacrogol EVS,may become an optimal therapy to control esophageal variceal bleeding and rebleeding.

Objective Dieulafoy's lesion is a rare cause of upper gastrointestinal bleeding. The purpose of this study was to recognize the clinical characteristics of gastric Dieulafoy and to identify possible predictive factors of rebleeding. Methods Retrospective study of patients with gastrointestinal bleeding secondary to Dieulafoy's lesion from January 2009 to June 2016. We analyzed the clinical data and endoscopic findings and the correlated with rebleeding risk factors with Dieulafoy's lesion. Results 111 patients were included in the study, 97 (87.4%) patients were male; the most common location of the bleeding lesions were Proximal stomach of 53 cases (47.7%); According to the Forrest type, 46.8% of the cases were arterial (spurting), 52.3% of the cases were arterial (oozing), there were 101 (91.0%) patients treated by endoscopic combined drug therapy. The success rate of Endoscopic hemostatic treatment was 84.2%, endoscopic hemostatic treatment success rate was as follows: single endoscopic, 85.0%; two endoscopic, 84.8%; three endoscopic, 75.0%. The hemostatic treatment success rate of 101 patients with endoscopic combined drug was as follows: Proximal stomach, 83.7%; mid-stomach, 82.1%; and distal stomach, 88.9%. Age (P = 0.002) and blood transfusion (P = 0.004) were risk factors for rebleeding in the study. Blood transfusion was associated with a higher recurrence rate for bleeding (P = 0.018, OR=37.77, 95% CI = 1.86~766.47) for 101 patients with endoscopic in combination with drug. Conclusion Endoscopic therapy is effective for treating Dieulafoy's lesion. The blood transfusion was associated with a high rate of bleeding recurrence. There were no significant differences between the rebleeding and non-rebleeding groups with respect to bleeding location or hemostatic methods.
