| 1 | The role of gut microbiota(commensal bacteria)and the mucosal barrier in the pathogenesis of inflammatory and autoimmune diseases and cancer:contribution of germ-free and gnotobiotic animal models of human diseases显示文摘Metagenomic approaches are currently being used to decipher the genome of the microbiota(microbiome),and,in parallel,functional studies are being performed to analyze the effects of the microbiota on the host.Gnotobiological methods are an indispensable tool for studying the consequences of bacterial colonization.Animals used as models of human diseases can be maintained in sterile conditions(isolators used for germ-free rearing)and specifically colonized with defined microbes(including non-cultivable commensal bacteria).The effects of the germ-free state or the effects of colonization on disease initiation and maintenance can be observed in these models.Using this approach we demonstrated direct involvement of components of the microbiota in chronic intestinal inflammation and development of colonic neoplasia(i.e.,using models of human inflammatory bowel disease and colorectal carcinoma).In contrast,a protective effect of microbiota colonization was demonstrated for the development of autoimmune diabetes in non-obese diabetic(NOD)mice.Interestingly,the development of atherosclerosis in germ-free apolipoprotein E(ApoE)-deficient mice fed by a standard low-cholesterol diet is accelerated compared with conventionally reared animals.Mucosal induction of tolerance to allergen Bet v1 was not influenced by the presence or absence of microbiota.Identification of components of the microbiota and elucidation of the molecular mechanisms of their action in inducing pathological changes or exerting beneficial,disease-protective activities could aid in our ability to influence the composition of the microbiota and to find bacterial strains and components(e.g.,probiotics and prebiotics)whose administration may aid in disease prevention and treatment. | Helena Tlaskalova-Hogenova Renata Stepankova Hana Kozakova Tomas Hudcovic Luca Vannucci Ludmila Tuckova Pavel Rossmann TomasHrncır Miloslav Kverka Zuzana Zakostelska Klara Klimesova Jaroslava Pribylova Jirina Bartova Daniel Sanchez Petra Fundova Dana Borovska Dagmar Sru˚tkova Zdenek Zıdek Martin Schwarzer Pavel Drastich David P Funda | 2011 | Cellular & Molecular Immunology2011，8，2： | 47 |

| 3 | Longitudinal molecular characterization of endoscopic specimens from colorectal lesions显示文摘AIM: To compare molecular profiles of proximal colon, distal colon and rectum in large adenomas, early and late carcinomas. To assess feasibility of testing directed at molecular markers from this study in routine clinical practice. METHODS: A prospective 3-year study has resulted in the acquisition of samples from 159 large adenomas and 138 carcinomas along with associated clinical parameters including localization, grade and histological type for adenomas and localization and stage for carcinomas. A complex molecular phenotyping has been performed using multiplex ligation-dependent probe amplification technique for the evaluation of Cp G-islandmethylator phenotype(CIMP), PCR fragment analysis for detection of microsatellite instability and denaturing capillary electrophoresis for sensitive detection of somatic mutations in KRAS, BRAF, TP53 and APC genes.RESULTS: Molecular types according to previously introduced Jass classification have been evaluated for large adenomas and early and late carcinomas. An increase in CIMP+ type, eventually accompanied with KRAS mutations, was notable between large adenomas and early carcinomas. As expected, the longitudinal observations revealed a correlation of the CIMP+/BRAF + type with proximal location. CONCLUSION: Prospective molecular classification of tissue specimens is feasible in routine endoscopy practice. Increased frequency of some molecular types corresponds to the developmental stages of colorectal tumors. As expected, a clear distinction is notable for tumors located in proximal colon supposedly arising from the serrated(methylation) pathway. | Petra Minarikova Lucie Benesova Tereza Halkova Barbora Belsanova Stepan Suchanek Jiri Cyrany Inna Tuckova Jan Bures Miroslav Zavoral Marek Minarik | 2016 | World Journal of Gastroenterology2016，22，20： | 2 |

| 16 | Improved specimen adequacy using jumbo biopsy forceps in patients with Barrett's esophagus显示文摘AIM:To assess the sampling quality of four different forceps(three large capacity and one jumbo) in patients with Barrett's esophagus.METHODS:This was a prospective,single-blind study.A total of 37 patients with Barrett's esophagus were enrolled.Targeted or random biopsies with all four forceps were obtained from each patient using a diagnostic endoscope during a single endoscopy.The following forceps were tested:A:FB-220 K disposable large capacity;B:BI01-D3-23 reusable large capacity;C:GBF-02-23-180 disposable large capacity;and jumbo:disposable Radial Jaw 4 jumbo.The primary outcome measurement was specimen adequacy,defined as a well-oriented biopsy sample 2 mm or greater with the presence of muscularis mucosa.RESULTS:A total of 436 biopsy samples were analyzed.We found a significantly higher proportion of adequate biopsy samples with jumbo forceps(71%)(P < 0.001 vs forceps A:26%,forceps B:17%,and forceps C:18%).Biopsies with jumbo forceps had the largest diameter(median 2.4 mm)(P < 0.001 vs forceps A:2 mm,forceps B:1.6 mm,and forceps C:2mm).There was a trend for higher diagnostic yield per biopsy with jumbo forceps(forceps A:0.20,forceps B:0.22,forceps C:0.27,and jumbo:0.28).No complications related to specimen sampling were observed with any of the four tested forceps.CONCLUSION:Jumbo biopsy forceps,when used with a diagnostic endoscope,provide more adequate specimens as compared to large-capacity forceps in patients with Barrett's esophagus. | Jan Martinek Jana Maluskova Magdalena Stefanova Inna Tuckova Stepan Suchanek Zuzana Vackova Jana Krajciova Marek Kollar Miroslav Zavoral Julius Spicak | 2015 | World Journal of Gastroenterology2015，21，17： | 0 |
