摘要
看起来是在 Helicobacter pylori (H pylori ) 和胃的癌症之间的强壮的协会。我们在胃的致癌作用上关于 H pylori 感染的效果考察了最近的证据,分类进传染病学,胃的粘膜变化的动力学, DNA 损坏,毒力因素,主人因素,和胃的恶意的来源。通过在对源于 H pylori 紧张之间的差别的毒力因素的研究取得的可观的进步,例如 cagA 确实,以及进主人因素,例如基因多型性,包括胃的癌症, H 联系 pylori 的疾病的一个多样的系列把自己正在借给说明。当发展研究上的胃的恶意的潜在的来源与兴趣尚待分晓,建议骨头髓的 Houghton 等推进的新奇假设的影响导出干细胞(BMDC ) 。进一步作为胃的癌症的可行预防在对 H pylori 根除,以及进胃的致癌作用的机制的研究进行,是急切地被等候当前的年并且在以外。
There appears to be the strong association between Helicobacter pylori (H pylori) and gastric cancer. We reviewed the latest evidences about the effects of H pylori infection on gastric carcinogenesis, classified into epidemiology, dynamics of gastric mucosal changes, DNA damages, virulence factors, host factors, and source of gastric malignancy. Through the considerable progress made in research into virulence factors resulting from differences between Hpylori strains, such as cagA positivity, as well as into host factors, such as gene polymorphisms, a diverse spectrum of H pyloriassociated diseases, including gastric cancer, is beginning to lend itself to elucidation. The impact of the novel hypothesis advanced by Houghton et al proposing bonemarrow derived stem cells (BMDC) as a potential source of gastric malignancy on evolving research remains to be seen with interest. Further progress in research into H pylori eradication as a viable prophylaxis of gastric cancer, as well as into the mechanisms of gastric carcinogenesis, is to be eagerly awaited for the current year and beyond.
