6%, 26.9%, 18.6%, 13.6%, 10.2% and 10.1% respectively with overlaps. Irrespective of the symptoms, endoscopic peptic ulcer disease was found

in 6.5% patients. Major indication for biopsy had been presence of endoscopic gastropathies which included antral gastritis, pangastritis, gastric ulcers and gastric carcinomas. Gastric carcinomas were found in 0.6% of the total cohort. Gastric ulcers and gastric carcinomas phosphatase inhibitor library are found in 3.3% and 2.0% respectively among chronic antral gastritis patients. Conclusion: Rapid urease test had a low correlation with antral gastritis due to multiple reasons. The significance of antral gastritis with symptoms was unclear perhaps with exception dyspepsia, gastric ulcers and gastric carcinomas. Prevalence of peptic ulcer disease and gastric malignancies was low with chronic antral gastriris in this series. Key Word(s): 1.

China Objective: Helicobacter pylori outer-membrane proteins (hom), especially learn more the homB gene, have been suggested as a novel virulence factor. However, few studies has been conducted in China regarding the association between these genes

and clinical outcome. In this study homA and homB gene were detected, to determine whether the homA and homB associated with clinical outcome of H. pylori infection, especially with gastric cancer. Methods: Pre-separation of the 170 clinical H. pylori strains for resuscitation culture, and extraction its genomic DNA; PCR was performed to study the presence of the homA and homB. Results: In the 170 strains, among them, gastric cancer 28 strains, gastric ulcer 19 strains, duodenal ulcer 75 strains, gastritis 48 strains. The expression rate of homA in gastric cancer, gastric ulcer, duodenal ulcer and gastritis were 25.0% (7/28), 26.3% (5/19), 32.0 (24/75), 31.3 (15/48), respectively; no significant difference among four groups (P > 0.05). The expression rate of homB in gastric cancer, gastric ulcer, duodenal ulcer and gastritis were 78.6% (22/28), 78.9% (15/19), 86.7 (65/75), 89.6 (43/48), respectively; no significant difference among four groups (P > 0.05). Conclusion: In all digestive diseases homB was highly expressed, especially in gastritis. Hom genes might not be a good indicator for disease prediction in the China. More studies are needed to confirm these results and determine the function of intermediate length hom. Key Word(s): 1. Helicobacter pylori; 2. Digestive diseases; 3.
