| 1 | Helicobacter pylori vac A genotype is a predominant determinant of immune response to Helicobacter pylori CagA显示文摘AIM To evaluate the frequency of Helicobacter pylori(H. pylori) Cag A antibodies in H. pylori infected subjects and to identify potential histopathological and bacterial factors related to H. pylori Cag A-immune response.METHODS Systematic data to H. pylori isolates, blood samples, gastric biopsies for histological and molecular analyses were available from 99 prospectively recruited subjects. Serological profile(anti-H. pylori, anti-Cag A) was correlated with H. pylori isolates(cag A, EPIYA, vac A s/m genotype), histology(Sydney classification) and mucosal interleukin-8(IL-8) m RNA and protein expression. Selected H. pylori strains were assessed for H. pylori Cag A protein expression and IL-8 induction in co-cultivation model with AGS cells.RESULTS Thirty point three percent of microbiologically confirmed H. pylori infected patients were seropositive for Cag A. Majority of H. pylori isolates were cag A gene positive(93.9%) with following vac A polymorphisms: 42.4% vac A s1m1, 23.2% s1m2 and 34.3% s2m2. Anti-Cag AIg G seropositivity was strongly associated with atrophic gastritis, increased mucosal inflammation according to the Sydney score, IL-8 and cag A m RNA expression. V a c A s a n d m p o l y m o r p h i s m s w e r e t h e m a j o r determinants for positive(vac A s1m1) or negative(vac A s2m2) anti-Cag A serological immune response, which also correlated with the in vitro inflammatory potential in AGS cells. In vitro co-cultivation of representative H. pylori strains with AGS cells confirmed functional Cag A translocation, which showed only partial correlation with Cag A seropositivity in patients, supporting vac A as major co-determinant of the immune response.CONCLUSION Serological immune response to H. pylori cag A + strain in H. pylori infected patients is strongly associated with vac A polymorphism, suggesting the crucial role of bacterial factors in immune and clinical phenotype of the infection. | Alexander Link Cosima Langner Wiebke Schirrmeister Wiebke Habendorf Jochen Weigt Marino Venerito Ina Tammer Dirk Schlüter Philipp Schlaermann Thomas F Meyer Thomas Wex Peter Malfertheiner | 2017 | World Journal of Gastroenterology2017,23,26: | 12 |

| 3 | Sporadic versus hereditary gastrinomas of the duodenum and pancreas: Distinct clinico-pathological and epidemiological features显示文摘Gastrinomas are defined as gastrin secreting tumors that are associated with Zollinger-Ellison syndrome (ZES). ZES is characterized by elevated fasting gastrin serum levels, positive secretin stimulation test and clinical symptoms such as recurrent peptic ulcer disease, gastroesophageal re?ux disease and occasional diarrhea. Genetically, nonhereditary (sporadic) gastrinomas are distinguished from hereditary gastrinomas, which are associated with multiple endocrine neoplasia type 1 (MEN1) syndrome. In general, duodenal gastrinomas are small and solitary if they are sporadic and multiple as well as hereditary. The sporadic gastrinomas occur in the duodenum or in the pancreas while the hereditary gastrinomas almost all occur in the duodenum. Our series of 77 sporadic duodenal neuroendocrine tumors (NETs) includes 18 patients (23.4%) with gastrinomas and ZES. Of 535 sporadic NETs in the pancreas collected from the NET archives of the departments of pathology in Zürich, Switzerland, and Kiel, Germany, 24 patients (4.5%) suffered from sporadic pancreatic gastrinomas and ZES. These NETs have to be distinguished fromtumors with immunohistochemical positivity for gastrin but without evidence of ZES. An additional 19 patients suffered from MEN1 and ZES. These patients showed exclusively duodenal gastrinomas, but not pancreatic gastrinomas. The prognosis of sporadic and MEN1- associated duodenal gastrinomas is better than that of pancreatic gastrinomas, since they progress slowly to liver metastasis. In summary, sporadic and MEN1- associated gastrinomas in the duodenum and pancreas show different clinico-pathological and genetic features. The incidence of sporadic duodenal gastrin-producing tumors is increasing, possibly due to optimized diagnostic procedures. In contrast, pancreatic MEN1- associated gastrinomas seem to be extremely rare. A considerable subset of tumors with immunohistochemical expression of gastrin but without evidence of ZES should be designated as functionally inactive NETs expressing gastrin, but not as gastrinomas. | Martin Anlauf Nele Garbrecht Tobias Henopp Anja Schmitt Regina Schlenger Andreas Raffel Markus Krausch Oliver Gimm Claus F Eisenberger Wolfram T Knoefel Henning Dralle Paul Komminoth Philipp U Heitz Aurel Perren Günter Klppel | 2006 | World Journal of Gastroenterology2006,12,34: | 7 |
| 4 | Dynamic magnetic resonance defecography in 10 asymptomatic volunteers显示文摘AIM: Evaluation of the wide range of normal findings in asymptomatic women undergoing dynamic magnetic resonance (MR) defecography. METHODS: MR defecography of 10 healthy female volunteers (median age: 31 years) without previous pregnancies or history of surgery were evaluated. The rectum was filled with 180 mL gadolinium ultrasound gel mixture. MR defecography was performed in the supine position. The pelvic floor was visualized with a dynamic T2-weighted sagittal plane where all relevant pelvic floor organs were acquired during defecation. The volunteers were instructed to relax and then to perform straining maneuvers to empty the rectum. The pubococcygeal line (PCGL) was used as the line of reference. The movement of pelvic floor organs was measured as the vertical distance to this reference line. Data were recorded in the resting position as well as during the defecation process with maximal straining. Examinations were performed and evaluated by two experienced abdominal radiologists without knowledge of patient history. RESULTS: Average position of the anorectal junction was located at -5.3 mm at rest and -29.9 mm during straining. The anorectal angle widened significantly from 93° at rest to 109° during defecation. A rectocele was diagnosed in eight out of 10 volunteers showing an average diameter of 25.9 mm. The bladder base was located at a position of +23 mm at rest and descended to -8.1 mm during defecation in relation to the PCGL. The bladder base moved below the PCGL in six out of 10 volunteers, which was formally defined as a cystocele. The uterocervical junction was located at an average level of +43.1 mm at rest and at +7.9 mm during straining. The uterocervical junction of three volunteers fell below the PCGL; described formally as uterocervical prolapse. CONCLUSION: Based on the range of standard values in asymptomatic volunteers, MR defecography values for pathological changes have to be re-evaluated. | Andreas G Schreyer Christian Paetzel Alois Fürst Lena M Dendl Elisabeth Hutzel René Müller-Wille Philipp Wiggermann Stephan Schleder Christian Stroszczynski Patrick Hoffstetter | 2012 | World Journal of Gastroenterology2012,18,46: | 7 |
| 5 | 鸡后根神经节多巴胺细胞在体及体外培养中的免疫细胞化学观察显示文摘应用免疫细胞化学PAP法,研究了鸡胚和雏鸡后根神经节细胞内多巴胺递质的表现与胚胎发育过程中的变化,并在细胞培养条件下研究了周围靶组织——皮肤对后根节细胞胚胎发育的影响。鸡后根节细胞内多巴胺的免疫反应最先出现于E_(10),只占后根节细胞的0.8%,E_(18)时达5.6%,出壳后雏鸡为8.6%。在鸡后根节内,多巴胺免疫反应阳性细胞主要为较大的A类细胞,和极少较小的B类细胞。免疫反应阳性的周围神经末梢位于皮肤和交感干内。当取自E_9的鸡胚后根节细胞经7天培养后,部分神经细胞出现多巴胺免疫反应阳性;而取自E_6的鸡胚后根节细胞虽经10天培养后仍为免疫反应阴性;然而,将取自E_6后根节细胞与皮肤组织联合培养10天后,少量神经细胞及轴突出现多巴胺免疫阳性反应。作者认为:鸡后根节多巴胺细胞在胚胎时期的发育有赖于周围靶组织的作用。 | 周长满 Philippe E Audet G Geffard M Gaulin F | 1992 | 神经解剖学杂志1992,8,2: | 4 |
