慢性萎缩性胃炎(CAG)是消化系统常见病,目前病因尚不清楚,且临床缺乏满意疗效。近年来国内外学者对胃内幽门螺旋杆菌(HP),进行了多方面的研究,多数人认为HP感染与胃窦炎、溃肠病密切相关,但是否能引起萎缩性胃炎尚未定 Chronic atrophic gastritis (CAG) is a common disease of the digestive system. The etiology is not yet clear, and there is a lack of clinical efficacy. In recent years, scholars at home and abroad have conducted various researches on Helicobacter pylori (HP) in the stomach. Most people think that HP infection is closely related to antral gastritis and ulcer disease, but whether it can cause atrophic gastritis has not yet been determined.
