| 1 | Cholecystectomy and the risk of alimentary tract cancers:A systematic review显示文摘AIM: To investigate the association between cholecystectomy and gastro-intestinal tract(GIT) cancers.METHODS: We conducted a systematic review according to the PRISMA guidelines. A MEDLINE search was performed with predefined search criteria for English Language articles on the association between cholecystectomy and GIT cancers. Additional articles were retrieved by manual search of references. All relevant articles were accessed in full text. Data onstudy type; cases; controls; country; effect estimate; adjustments for confounders and quality of publication were extracted. The quality of the publications were scored by adherence to the STROBE checklist. The data for each part of the GIT were presented in separate tables.RESULTS: Seventy-five studies and 5 meta-analyses satisfied the predefined criteria for inclusion and were included in this review. There were inconsistent reports and no strong evidence of an association between cholecystectomy and cancers of the oesophagus(Adenocarcinoma), pancreas, small bowel and rightsided colon cancers. In squamous cancer of the oesophagus, cancers of the stomach, liver, bile ducts, small bowel and left sided colon cancers, good quality studies suggested a lack of association with cholecystectomy. Equally, distal colon and rectal cancers were found not to be associated with cholecystectomy. Several mechanisms for carcinogenesis/promotion of carcinogensis have been proposed. These have focused on a role for bile salts in carcinogenesis with several potential mutagenic molecular events and gut metabolic hormones signaling cell proliferation or initiation of carcinogenesis.CONCLUSION: This is a comprehensive review of the association between GIT cancers and cholecystectomy. This review found no clear association between cholecystectomy and GIT cancers. | Maria Coats Sami M Shimi | 2015 | World Journal of Gastroenterology2015，21，12： | 12 |
| 2 | 胆囊切除术与消化道癌症的风险:一项系统性综述显示文摘目的研究胆囊切除术与胃肠道(gastro-intestinal tract,GIT)癌症的关系。方法我们遵循PRISMA(译者注)指南进行了这项系统性综述。借助Medline用预设检索标准对有关胆囊切除与GIT癌症的英文文献进行检索。通过手工查询参考文献的方法得到其他文献。所有文献都得到了全文。从中提取的数据包括:研究类型、病例数、对照、国家、效度、混杂因素的校正和文献质量。采用STROBE(译者注)核查表对文献质量进行评分。GIT每个部位的数据录入不同的表格。结果有75项研究和5项meta分析符合预选标准进入这项综述。入选的研究结果相互矛盾,没有强的证据表明胆囊切除与食管癌(腺癌)、胰腺癌、小肠癌以及右半结肠癌有关。高质量的研究中,胆囊切除与食管鳞癌、胃癌、肝癌、胆管癌、小肠癌、左半结肠癌没有关系。同样,远端结肠癌和直肠癌也没有观察到与胆囊切除有关。文献提出了一些致癌或促癌的机理,这些机理集中在胆汁酸盐对一些潜在突变分子的致癌作用以及作用于GIT代谢激素,这些代谢激素信号可以导致细胞增殖或癌症生成。结论这是一项关于胆囊切除与GIT癌症关系的综合性综述,结果没有显示胆囊切除与GIT癌症之间有明确的联系。 | 郭绍红 Maria Coats Sami M Shimi | 2017 | 中国微创外科杂志2017，17，1： | 12 |
| 3 | Is the pain in chronic pancreatitis of neuropathic origin? Support from EEG studies during experimental pain显示文摘AIM: To prove the hypothesis that patients with chronic pancreatitis would show increased theta activity during painful visceral stimulation. METHODS: Eight patients and 12 healthy controls underwent an experiment where the esophagus was electrically stimulated at the pain threshold using a nasal endoscope. The electroencephalogram (EEG) was recorded from 64 surface electrodes and 'topographic matching pursuit' was used to extract the EEG information in the early brain activation after stimulation. RESULTS: A major difference between controls and patients were seen in delta and theta bands, whereas there were only minor differences in other frequency bands. In the theta band, the patients showed higher activity than controls persisting throughout the 450 ms of analysis with synchronous brain activation betweenthe channels. The main theta components oscillated with 4.4 Hz in the patients and 5.5 Hz in the controls. The energy in the delta (0.5-3.5 Hz) band was higher in the controls, whereas the patients only showed scattered activity in this band. CONCLUSION: The differences in the theta band indicate that neuropathic pain mechanisms are involved in chronic pancreatitis. This has important implications for the understanding and treatment of pain in these patients, which should be directed against drugs with effects on neuropathic pain disorders. | AsbjФrn M Drewes Maciej Gratkowski Saber AK Sami Georg Dimcevski Peter Funch-Jensen Lars Arendt-Nielsen | 2008 | World Journal of Gastroenterology2008，14，25： | 4 |
| 4 | Effectiveness of hepatitis B virus vaccination program in Egypt:Multicenter national project显示文摘AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated children.METHODS:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to < 10,10 to < 15 and ≥ 15 years respectively compared to those < 5 years and 1.1 among girls compared to boys with P < 0.01. HBs Ag was positive in 0.11% and breakthrough infection was 0.36% and 0.39% depending on positivity of anti-HBc and DNA detection respectively. The prevalence of HBV infection was significantly higher among children aged ≥ 7 years(0.59%) compared to 0.07% among younger children with odds ratio equal to 8.4(95%CI:1.1-64.2) and P < 0.01.The prevalence was higher among girls(0.48%) than boys(0.29%) with P > 0.05. C ON C LU S I ON :T he E gy pt ian c ompuls or y H B V vaccination program provides adequate protection. Occult HBV infection exists among apparently healthy vaccinated children. Adherence to infection control measures is mandatory. | Iman I Salama Samia M Sami Zeinab Nabil Ahmed Said Manal H El-Sayed Lobna A El Etreby Thanaa M Rabah Dalia M Elmosalami Amany T Abdel Hamid Somaia I Salama Aida M Abdel Mohsen Hanaa M Emam Safaa M Elserougy Amal I Hassanain Naglaa F Abd Alhalim Fatma A Shaaban Samia A Hemeda Nihad A Ibrahim Ammal M Metwally | 2015 | World Journal of Hepatology2015，7，22： | 2 |
| 5 | Prevalence of microscopic colitis in patients with diarrhea of unknown etiology in Turkey显示文摘AIM: To investigate the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey. METHODS: Between March, 1998 to July, 2005, 129 patients with chronic non-bloody diarrhea of unexplained etiology who had undergone full colonoscopy with no obvious abnormalities were included in the study. Two biopsies were obtained from all colonic segments and terminal ileum for diagnosis of microscopic colitis. On histopathologic examination, criteria for lymphocytic colitis (intraepithelial lymphocyte ≥ 20 per 100 intercryptal epithelial cells, change in surface epithelium, mononuclear infiltration of the lamina propria) and collagenous colitis (subepithelial collagen band thickness ≥ 10 μm) were explored. RESULTS: Lymphocytic colitis was diagnosed in 12 (9%) patients (Female/Male: 7/5, mean age: 45 year, range: 27-63) and collagenous colitis was diagnosed in only 3 (2.5%) patients (all female, mean age: 60 years, range: 54-65).CONCLUSION: Biopsy of Turkish patients with the diagnosis of chronic non-bloody diarrhea of unexplained etiology and normal colonoscopic findings will reveal microscopic colitis in approximately 10% of the patients. Lymphocytic colitis is 4 times more frequent than collagenous colitis in these patients. | Levent Erdem Sadιk Yιldιrιm Nihat Akbayιr Banu Yιlmaz Necati Yenice Orhan Sami Gültekin nder Peker | 2008 | World Journal of Gastroenterology2008，14，27： | 2 |
