Objective To investigate the value of microsphere embolism in hepatocellular carcinoma with TACE. Methods A prospective controlled study was performed. One hundred and eighty patients were divided into the microsphere embolism embolization group, the lipiodol embolization group and the united embolization group. Comparations of the TTP, the interphase of treatment before TTP and the survival curves were performed among the three groups. Differences of the liver function, the WBC number, changes of vascular morphology and complications before and 1 month after treatment were analyzed. Results No statistic differences in the TTP, the survival curves, the liver function, the WBC number, changes of vascular morphology and complications were found among the three group (P > 0.05). No significant difference in the interphase of treatment before TTP was found between the embolism embolization group and the lipiodol embolization group (P>0.05). Significant difference of the interphase of treatment was found between the lipiodol embolization group and the embolism embolization group or the united embolization group(P<0.05). Conclusion The microspheres embolism with TACE is safe, which can extend the interphase of treatment before TTP, but can not extend the TTP and survival curves.

Stem cells are those with long-term self-renewal and produce differentiated cells at least one end of the cell capacity. Stem cell transplantation can be used for the treatment of many kind of liver diseases which includes acute liver failure, inherited metabolic liver diseases, as well as end-stage liver disease. This Article summarizes the types of stem cell types applied for treatment of liver diseases, stem cell tracing technology, as well as the clinical application of stem cells. It also discusses the problems existed and the research focus.

Objective KG1This study is to evaluate defectography in postoperative defecation function of Hirschsprung′s disease (HD). KG2MethodsKG1 Between 1979 and 1993, 30 HD cases were treated operatively and followed-up by defectography. KG2ResultsKG1 Thirty cases were classified into 3 groups, according to the standard quantitative clinical scoring systems with the stooling score from 0 to 14. There were 4 cases (13%) graded as excellent (maximum score of 14) with normal bowel habit, 21 cases (70%) as good (score between 10～13) with minor continence problems, 5 cases (16 7%) as fair (score between 5～9) with marked limitations in social life. Anorectal manometry study showed that the anal resting pressure and voluntary sphincter force (maximal queeze pressure minus resting pressure) in fair group were significantly lower than that in control group( P

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 investigate the risk factors for post-ERCP complications. Methods Data of the patients who underwent ERCP in the First Affiliated Hospital of Nanchang University from 1 January 2011 to 31 December 2013 were retrospectively analyzed. Post-ERCP complications were analyzed by univariate and multivariate analyses. Results A total of 277 patients out of 1 951 developed complications, 101(5.18%)pancreatitis, 54(2.77%)hyperamylasemia(not including pancreatitis), 134(6.87%) biliary infection,8(0.41%)hemorrhage,1(0.05%)obstruction and 1(0.05%)perforation.Multivariate analyses showed cholangiocarcinoma(P=0.002,OR=2.39, 95% CI:1.38-4.14), long operation time(>60 min)(P=0.020,OR=3.77,95%CI:1.23-11.53)and endoscopic sphincterotomy(EST)(P=0.008, OR=2.56,95% CI:1.28-5.14)and entrance of guidewire to pancreatic duct(P=0.012,OR=1.43, 95%CI:1.08-1.87)were independent risk factors for PEP. Cholangiocarcinoma(P<0.01, OR=2.93, 95%CI:1.88-4.56),multiple times of ERCP during the period of hospitalization(P<0.01, OR=2.53, 95%CI:1.63-3.93)were independent risk factors for post-cholangitis. However, EST(P=0.03, OR=0.65,95%CI:0.44-0.97)and antibiotics prophylaxis after ERCP(P=0.03, OR=0.64, 95% CI:0.39-0.95)were protective factors for post-cholangitis. ConclusionCholangiocarcinoma, endoscopic sphincterotomy, long operation time(> 60 min)and entrance of guidewire to pancreatic duct were independent risk factors for PEP. Cholangiocarcinoma and multiple ERCP during the period of hospitalization are independent risk factors for post-cholangitis.EST and antibiotics prophylaxis after ERCP might reduce the occurrence of cholangitis.

Objective To investigate the effects of antibiotic prophylaxis on post-operation complications after endoscopic retrograde cholangio-pancreatography (ERCP).Methods From January 1st,2011 to December 31st,2013,1 951 patients undergoing ERCP were enrolled and divided into postoperative antibiotic prophylaxis group (antibiotics group,630 cases) and postoperative non-antibiotic treatment group (non-antibiotics group,1 321 cases).Complications after ERCP were compared between the two groups.Chi square test,single factor analysis and multiple factor analysis were performed for statistical analysis.Results Among the 1 951 patients,277 patients had postoperative complications:101 patients (5.18％) with post-endoscopic retrograde cholangio-pancreatography pancreatitis (PEP),54 patients (2.77％) with hyperamylasemia,134 patients (6.87％) with biliary infection,eight patients (0.41％) with hemorrhage,one patient (0.05％) with intestinal obstruction and one patient (0.05％) with perforation.The incidence of postoperative biliary infection of antibiotics group was 4.44％ (28/630),which was lower than that of non-antibiotics group (8.02％,106/1 321),and the difference was statistically significant (x2 =8.546,P =0.030).The incidences of PEP of antibiotics group and nonantibiotics group were 4.92％ (31/630) and 5.30％ (70/1 321),respectively.The incidences of postoperative hyperamylasemia of antibiotics group and non-antibiotics group were 3.02％oo (19/630) and 2.65％ (35/1 321),respectively.The incidences of upper gastrointestinal hemorrhage were 3.02％ (19/630) and 2.65％ (35/1 321),respectively.The incidences of intestinal obstruction were 0 (0/630) and 0.08％ (1/1 321),respectively,while the incidences of perforation post-operation were 0.16％ (1/630) and 0 (0/1 321),respectively,and the differences were not statistically significant (all P＞0.05).Cholangiocarcinoma (odd ratios (OR)=2.93,95％ confidence interval (CI) 1.88 to 4.56,P＜0.01) and repeated ERCP during hospitalization (OR=2.53,95 ％ CI 1.63 to 3.93,P＜0.01) were the independent risk factors of cholangitis after operation.However,endoscopic sphincterotomy (OR=0.65,95 ％ CI 0.44 to 0.97,P =0.030) and antibiotics prophylaxis (OR =0.64,95％ CI 0.39 to 0.95,P =0.030) were the protective factors.Conclusions Antibiotic prophylaxis after ERCP can reduce the occurrence of postoperative cholangitis.Paitents with cholangiocarcinoma,repeated ERCP procedures during hospitalization or without endoscopic sphincterotomy should be recommended for antibiotic prophylaxis.
