1Roux-en-Y versus BillrothⅠreconstruction after distal gastrectomy for gastric cancer:A meta-analysis显示文摘AIM:To conduct a meta-analysis to compare Rouxen-Y(R-Y) gastrojejunostomy with gastroduodenal Billroth Ⅰ(B-Ⅰ) anastomosis after distal gastrectomy(DG) for gastric cancer.METHODS:A literature search was performed to identify studies comparing R-Y with B-Ⅰ after DG for gastric cancer from January 1990 to November 2012 in Medline,Embase,Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in The Cochrane Library.Pooled odds ratios(OR) or weighted mean differences(WMD) with 95%CI were calculated using either fixed or random effects model.Operative outcomes such as operation time,intraoperative blood loss and postoperative outcomes such as anastomotic leakage and stricture,bile reflux,remnant gastritis,reflux esophagitis,dumping symptoms,delayed gastric emptying and hospital stay were the main outcomes assessed.Meta-analyses were performed using RevMan 5.0 software(Cochrane library).RESULTS:Four randomized controlled trials(RCTs) and 9 non-randomized observational clinical studies(OCS) involving 478 and 1402 patients respectively were included.Meta-analysis of RCTs revealed that R-Y reconstruction was associated with a reduced bile reflux(OR 0.04,95%CI:0.01,0.14;P < 0.00 001) and remnant gastritis(OR 0.43,95%CI:0.28,0.66;P = 0.0001),however needing a longer operation time(WMD 40.02,95%CI:13.93,66.11;P = 0.003).Metaanalysis of OCS also revealed R-Y reconstruction had a lower incidence of bile reflux(OR 0.21,95%CI:0.08,0.54;P = 0.001),remnant gastritis(OR 0.18,95%CI:0.11,0.29;P < 0.00 001) and reflux esophagitis(OR 0.48,95%CI:0.26,0.89;P = 0.02).However,this reconstruction method was found to be associated with a longer operation time(WMD 31.30,95%CI:12.99,49.60;P = 0.0008).CONCLUSION:This systematic review point towards some clinical advantages that are rendered by R-Y compared to B-Ⅰ reconstruction post DG.However there is a need for further adequately powered,welldesigned RCTs comparing the same.Jun-Jie Xiong Kiran Altaf Muhammad A Javed Quentin M Nunes Wei Huang Gang Mai Chun-Lu Tan Rajarshi Mukherjee Robert Sutton Wei-Ming Hu Xu-Bao Liu 2013World Journal of Gastroenterology2013,19,7:33
2Meta-analysis of laparoscopic vs open liver resection for hepatocellular carcinoma显示文摘AIM:To conduct a meta-analysis to determine the safety and efficacy of laparoscopic liver resection(LLR) and open liver resection(OLR) for hepatocellular carcinoma(HCC).METHODS:PubMed(Medline),EMBASE and Science Citation Index Expanded and Cochrane Central Register of Controlled Trials in the Cochrane Library were searched systematically to identify relevant comparative studies reporting outcomes for both LLR and OLR for HCC between January 1992 and February 2012.Two authors independently assessed the trials for inclusion and extracted the data.Meta-analysis was performed using Review Manager Version 5.0 software(The Cochrane Collaboration,Oxford,United Kingdom).Pooled odds ratios(OR) or weighted mean differences(WMD) with 95%CI were calculated using either fixed effects(Mantel-Haenszel method) or random effects models(DerSimonian and Laird method).Evaluated endpoints were operative outcomes(operation time,intraoperative blood loss,blood transfusion requirement),postoperative outcomes(liver failure,cirrhotic decompensation/ascites,bile leakage,postoperative bleeding,pulmonary complications,intraabdominal abscess,mortality,hospital stay and oncologic outcomes(positive resection margins and tumor recurrence).RESULTS:Fifteen eligible non-randomized studies were identified,out of which,9 high-quality studies involving 550 patients were included,with 234 patients in the LLR group and 316 patients in the OLR group.LLR was associated with significantly lower intraoperative blood loss,based on six studies with 333 patients [WMD:-129.48 mL;95%CI:-224.76-(-34.21) mL;P = 0.008].Seven studies involving 416 patients were included to assess blood transfusion requirement between the two groups.The LLR group had lower blood transfusion requirement(OR:0.49;95%CI:0.26-0.91;P = 0.02).While analyzing hospital stay,six studies with 333 patients were included.Patients in the LLR group were found to have shorter hospital stay [WMD:-3.19 d;95%CI:-4.09-(-2.28) d;P < 0.00001] than their OLR counterpart.Seven studies including 416 patients were pooled together to estimate the odds of developing postoperative ascites in the patient groups.The LLR group appeared to have a lower incidence of postoperative ascites(OR:0.32;95%CI:0.16-0.61;P = 0.0006) as compared with OLR patients.Similarly,fewer patients had liver failure in the LLR group than in the OLR group(OR:0.15;95%CI:0.02-0.95;P =0.04).However,no significant differences were found between the two approaches with regards to operation time [WMD:4.69 min;95%CI:-22.62-32 min;P = 0.74],bile leakage(OR:0.55;95%CI:0.10-3.12;P = 0.50),postoperative bleeding(OR:0.54;95%CI:0.20-1.45;P = 0.22),pulmonary complications(OR:0.43;95%CI:0.18-1.04;P = 0.06),intra-abdominal abscesses(OR:0.21;95%CI:0.01-4.53;P = 0.32),mortality(OR:0.46;95%CI:0.14-1.51;P = 0.20),presence of positive resection margins(OR:0.59;95%CI:0.21-1.62;P = 0.31) and tumor recurrence(OR:0.95;95%CI:0.62-1.46;P = 0.81).CONCLUSION:LLR appears to be a safe and feasible option for resection of HCC in selected patients based on current evidence.However,further appropriately designed randomized controlled trials should be undertaken to ascertain these findings.Jun-Jie Xiong Kiran Altaf Muhammad A Javed Wei Huang Rajarshi Mukherjee Gang Mai Robert Sutton Xu-Bao Liu Wei-Ming Hu 2012World Journal of Gastroenterology2012,18,45:25
3Elevated serum alpha fetoprotein levels promote pathological progression of hepatocellular carcinoma显示文摘AIM:To investigate the biological role of alpha fetoprotein (AFP) and its clinical signif icance in carcinogenesis of hepatocellular carcinoma (HCC).METHODS:Clinical analysis of HCC patients and im-munohistochemical examination were conducted to evaluate the relationship between serum AFP level and patient mortality. Confocal microscopy,Western blotting, dimethylthiahzolyl-2,5-diphenyl-tetrazolium bromide,Cell Counting Kit-8 assays and flow cytometry were performed to explore the possible mechanism.RESULTS: Among the 160 HCC patients enrolled in this study,130 patients survived 2 years (81.25%),with a survival rate of 86.8% in AFP < 2 0 μg/L group,88.9% in AFP 20-250 μg/L group,and 69.6% in AFP > 250 μg/L group, demonstrating a higher mortality rate in HCC patients with higher AFP levels. Surgical treatment was benef icial only in patients with low AFP levels.The mortality rate of HCC patients with high AFP levels who were treated surgically was apparently higher than those treated with conservative management.The results of immunohistochemistry showed that AFP and AFP receptor were merely expressed in tissues of HCC patients with positive serum AFP.Consistently,in vitro analysis showed that AFP and AFPS were expressed in HepG2 but not in HLE cells. AFP showed a capability to promote cell growth,and this was more apparent in HepG2 cells,in which the proliferation was increased by 3.5 folds. Cell cycle analysis showed that the percent-age of HepG2 cells in S phase after exposure to AFP was modestly increased.CONCLUSION:HCC patients with higher AFP levels show a higher mortality rate,which appears to be attributable to the growth promoting properties of AFP.Peng Li Shan-Shan Wang Hui Liu Ning Li Michael A McNutt Gang Li Hui-Guo Ding 2011World Journal of Gastroenterology2011,17,41:23
4Antihepatoma effect of alpha-fetoprotein antisense phosphorothioate oligodeoxyribonucleotides in vitro and in mice显示文摘AIM To evaluate antihepatoma effect ofantisense phosphorothioate oligodeo-xyribonucleotides (S-ODNs) targeted to alpha-fetoprotein (AFP) genes in vitro and in nudemice.METHODS AFP gene expression was examinedby immunocytochemical method or enzyme-linked immunosorbent assay. Effect of S-ODNson SMMC-7721 human hepatoma cell growth invitro was determined using microculturetetrazolium assay. In vivo antitumor activitiesof S-ODNs were monitored by measuring tumorweight differences in treated and control micebearing SMMC-7721 xenografts. Induction of cellapoptosis was evaluated by fluorescence-activated cell sorter (FACS) analysis.RESULTS Antisense S-ODN treatment led toreduced AFP gene expression. Specificantisense S-ODNs, but not control S-ODNs,inhibited the growth of heaptoma cells in vitro.In vivo. only antisense S-ODNs exhibitedobvious antitumor activities. FACS analysisrevealed that the growth inhibition by antisenseS. ODNs was associated with their cell apoptosisinduction.CONCLUSION Antisense S-ODNs targeted toAFP genes inhibit the growth of human hepatomacells and solid hepatoma, which is related totheir cell apoptosis induction.Xing Wang Wang~1 Jin Hui Yuan~1 Ru Gang Zhang~1 Li Xia Guo~1 Yong Xie~2 Hong Xie~1 ~1Department of Biotherapy,Shanghai Institute of Cell Biology,Chinese Academy of Sciences,Shanghai 200031,China ~2Department of Biology,Hong Kong University of Science and Technology,ChinaDr.Xing Wang Wang earned Ph.D.from Shanghai Institute of Materia Medical,Chinese Academy of Sciences in 1997.Now a professor at Shanghai Institute of Cell Biology,Chinese Academy of Sciences. 2001World Journal of Gastroenterology2001,7,3:21

7Targeting Gut Microbiota Dysbiosis: Potential Intervention Strategies for Neurological Disorders显示文摘It is well known that the gut microbiota plays an extremely important role in modulating host physiological functions such as immunity and metabolic homeostasis.In recent years,accumulated evidence has revealed that the gut microbiota can regulate the functions of the central nervous system(CNS)through the gut-brain axis,which provides a novel insight into the interactions between the gut and brain.This review focuses on the molecular mechanism of the crosstalk between the gut microbiota and the brain via the gut-brain axis,and on the onset and development of neurological disorders triggered by gut microbiota dysbiosis.These topics are followed by a critical analysis of potential intervention strategies targeting gut microbiota dysbiosis,including the use of probiotics,prebiotics,synbiotics,and diets.While research on the microbiota-gut-brain axis is still in its relative infancy,clarifying the molecular mechanism that underlies how the gut microbiota regulates neurological functions not only holds the promise of revealing potentially novel pathogeneses of neurological disorders,but also may lead to the development of potential diagnosis biomarkers and intervention strategies targeting microbiota dysbiosis for neurological disorders.Wanqiang Wu Qingmin Kong Peijun Tian Qixiao Zhai Gang Wang Xiaoming Liu Jianxin Zhao Hao Zhang Yuan Kun Lee Wei Chen a 2020Engineering2020,6,4:7
