为研究食管幽门螺杆菌（ＨＰ）与炎症的关系，设原发性食管炎１１０例为观察组，食管粘膜正常５０例对照组。全部病例经胃镜和食管粘膜分点活检组织学确诊。应用Ｗ－Ｓ染色显示和镜下观察ＨＰ分布。结果显示食管炎组有２５例ＨＰ感染，感染率２２．７３％，食管内ＨＰ感染各年龄组无差异（Ｐ＞０．０５），对照组未检出ＨＰ。提示患原发性食管炎时存在ＨＰ感染，推测这可作为致病因素之一
In order to study the relationship between Helicobacter pylori (HP) and inflammation, 110 cases of primary esophagitis were selected as observation group and 50 cases of normal esophageal mucosa as control group. All cases were confirmed by endoscopy and esophageal mucosa biopsy histology. W-S staining was used to display and microscopically observed HP distribution. The results showed that there were 25 cases of HP infection in esophagitis group, the infection rate was 22.73%. There was no significant difference in the HP infection among the esophageal groups (P> 0.05), but not in the control group. Suggesting that there is HP infection in patients with primary esophagitis, presumably as one of the risk factors
