根据胃液成分的6项参数,用POMS程序,就6种(510例)慢性胃病,按3种组合进行 Bayes 准则逐步判别。结果显示:1.胃癌、胃溃疡和萎缩性胃炎之间具有十分显著的差异,有判别作用的参数依次为 DNA、胆汁酸以及蛋白酶和游离酸;其判别距阵示萎缩性胃炎的符合率达78%。2.胃癌、胃溃疡和十二指肠溃疡3种病之间,胃液参数判别的差异亦十分显著;粘液、DNA、胆汁酸及 pH 值的判别效果有显著性;胃癌和十二指肠溃疡的判别符合率分别为63.3%及92%。3.浅表性、浅表-萎缩性和萎缩性胃炎进行判别时差异有显著意义,本组有判别作用的参数则依次为粘液、胆汁酸以及蛋白酶和pH值4项;判别距阵显示的符合率,萎缩性胃炎为51%,浅表性胃炎为75.8%,而浅表-萎缩性仅13%,表明后者具有很高的重叠性。
According to the six parameters of gastric juice composition, using the POMS procedure, 6 kinds (510 cases) of chronic gastropathy were progressively discriminated according to Bayes criteria according to 3 combinations. The results showed that:1. There were significant differences between gastric cancer, gastric ulcer and atrophic gastritis. The discriminating parameters were DNA, bile acid, protease and free acid. The discriminant distance from the array showed atrophic gastritis. 78%. Gastric juice, gastric ulcer and duodenal ulcer, the difference between the three kinds of gastric juice parameters is also very significant; mucus, DNA, bile acid and pH value discriminatory effect was significant; gastric cancer and duodenal ulcer The discriminant coincidence rates were 63.3% and 92%, respectively. The differences between superficial, superficial-atrophic and atrophic gastritis were significant. The discriminating parameters in this group were mucus, bile acid, protease and pH4; Conformity rates were 51% for atrophic gastritis, 75.8% for superficial gastritis, and only 13% for superficial-atrophic, indicating that the latter has a high degree of overlap.
