用原子吸收光谱仪对６６例常见上胃肠道疾病患者的血清、胃液中微量元素进行测定，并检测幽门螺杆菌（ＨＰ）感染情况，结果表明，萎缩性胃炎、胃溃疡、胃癌患者血液、胃液中铜、硒以及铜锌比例存在着差异，锌在３种疾病患者的胃液中亦存在明显差异。同时３种疾病均有不同程度ＨＰ阳性。提示上胃肠道疾病中存在着微量元素代谢紊乱，但与ＨＰ感染无一定相关性
The contents of trace elements in serum and gastric juice of 66 patients with common upper gastrointestinal diseases were measured by atomic absorption spectrometry and the infection of Helicobacter pylori (HP) was detected. The results showed that atrophic gastritis, gastric ulcer, gastric cancer, There are differences in copper, selenium and copper and zinc ratio, zinc in gastric juice in patients with three diseases there are also significant differences. At the same time, three kinds of diseases have different degrees of HP positive. Tip on the existence of gastrointestinal tract disorders of trace elements metabolism, but no certain relevance HP infection
