探讨Ｈｐ在胃癌高危人群胃内的分布情况。对胃癌高发区成年人群５３３人做内镜、快速尿素酶试验及４块胃粘膜活检组织学检查，Ｈｐ以组织学检查为标准，所有数据均做χ２检验。结果：１．人群Ｈｐ的检出率为６４．５４％。２．Ｈｐ在不同疾病及病变的检出率中，以活动性胃炎最高（９２．４３％），其次为十二指肠溃疡（８９．４７％），胃溃疡为（８３．３３％）。３．Ｈｐ在胃内分布情况：胃底部检出率最高（６１．５１％），其次为体小弯（５５．６６％），窦大弯（５１．２４％），窦小弯（５０．８５％）。胃底部Ｈｐ检出率明显高于窦部（Ｐ＜０．０１）。４．对不同活检部位进行组合比较Ｈｐ的检出率：胃窦小弯，体小弯，加胃底部３块组织的Ｈｐ检出率基本代表取４块组织的Ｈｐ检出率。
To investigate the distribution of Hp in the stomach of high-risk gastric cancer patients. 533 adult population of patients with high incidence of gastric cancer endoscopy, rapid urease test and 4 gastric biopsy histological examination, Hp to histological examination as a standard, all data were done χ2 test. Results: 1. The detection rate of human Hp was 64.54%. 2. The detection rate of Hp was the highest in active disease gastritis (92.43%), followed by duodenal ulcer (89.47%) and gastric ulcer (83.33%). 3. The distribution of Hp in the stomach was highest in the stomach (61.51%), followed by small bends (55.66%), large bends of the antrum (51.24%), and small bends of the antrum %). The detection rate of gastric Hp was significantly higher than that of the sinus (P <0.01). 4. The detection rate of Hp in different biopsy sites: The detection rate of Hp in the three tissues at the bottom of gastric antrum with small curve and slight curvature, and the bottom of gastric canal basically represents the detection rate of Hp in four tissues.
