本文分析６１５例幽门螺杆菌相关性胃炎及３８５例幽门螺杆菌非相关性胃炎。结果表明两者在非典型增生、肠上皮化生以及相关病变之间具有显著性差异（Ｐ＜０．０１）。据此结果，作者认为幽门螺杆菌的感染是胃粘膜非典型增生及肠上皮化生的危险因素之一。

The results showed that there was a significant difference between atypical hyperplasia, intestinal metaplasia and related pathological changes (P <0.01). According to the results, the authors believe that Helicobacter pylori infection is one of the risk factors of gastric mucosal atypical hyperplasia and intestinal metaplasia.
