摘要
The effects of Helicobacter pylori infection are strongly associated with chronic gastritis, gastric and duodenal ulcer, gastric cancer, and MALT lymphoma. The microorganism has been classified as a type I carcinogen by the World Health Organization. Varying clinical results from H. pylori infection are believed due, in part, to differences in virulence among species. The cag pathogenicity island is a complex of virulent genes and a coding region for the type IV phosphorylated secretion system. Through this system, many virulent gene products or proteins are phosphorylated into the host cells. This study demonstrated the positive CagA-phosphorylation effect of H. pylori in patients with chronic gastritis and benign gastric ulcer and revealed significantly different rates of CagA phosphorylation between these two diseases (P<.05).
