目的本研究旨在寻找一种简便可靠的诊断ＨＰ新方法。方法采用生化分析法测定了１００例经病理切片染色法 检出的各级ＨＰ感染患者空腹胃液氨浓度。结果：ＨＰ（－）２８例（１０．９７±２．３３ｍｍｏｌ／Ｌ，ＨＰ（＋）２８例（２１．９６±６．９８ｍｍｏｌ／Ｌ），ＨＰ （＋＋）３２例（３１．７９±１３．５４ｍｍｏｌ／Ｌ），ＨＰ（＋＋＋）１２例（４５．６８±１６．２３ｍｍｏｌ／Ｌ）组间差异（Ｐ＜０．０１）有非常显著意义。以１３、２９、 ４５ｍｍｏｌ／Ｌ为上限诊断ＨＰ（＋）（＋＋）（＋＋＋）感染，其敏感性分别为７８．６％，８７．５％，１００％，特异性分别为８７．３％，８９．５％，９２．８％。 故可作为定量诊断整体胃粘膜ＨＰ感染程度的一个有效指标。
Purpose The purpose of this study is to find a simple and reliable method for diagnosing HP. Methods The biochemical analysis was used to determine the fasting gastric ammonia concentration in 100 patients with HP infection at all levels detected by pathological staining. Results: HP (-) in 28 cases (10.97 ± 2.33mmol / L, HP (+) 28 cases (21.96 ± 6.98mmol / L, HP 32 cases (31.79 ± 13) 54mmol / L), HP (+++) in 12 cases (45.68 ± 16.23mmol / L), there was a significant difference (P <0.01) +) (+++), the sensitivity was 78.6%, 87.5%, 100%, respectively, and the specificity was 87.3%, 89.5%, 92.8% Quantitative diagnosis of overall gastric mucosal HP infection level of a valid indicator.
