通过对３０例胃癌患者的粘膜表面ｐＨ的测定来分析其酸碱环境情况，用以探讨胃癌与胃酸、胃癌与胃泌酸功能的关系。其结果为：低酸占５６．７％，无酸１３．３％，正常酸３０．０％，高酸０。总的胃酸缺乏占７０％。说明胃癌的发生与胃内低酸环境关系密切，提示恢复泌酸功能，改善胃内酸碱环境是防治胃癌的一条重要途径。
By measuring the pH value of mucosal surface in 30 patients with gastric cancer, the acid-base environment was analyzed to investigate the relationship between gastric cancer and gastric acid, gastric cancer and oxyntic acid function. As a result, low acid accounted for 56.7%, no acid 13.3%, normal acid 30.0%, and high acid 0. The total stomach acid deficiency accounts for 70%. It shows that the occurrence of gastric cancer is closely related to the low-acid environment in the stomach, suggesting that restoring oxyntic function and improving the acid-base environment in the stomach is an important approach to prevent and treat gastric cancer.
