细胞免疫功能的正常与否．影响着肿瘤的发生、进展及患者的预后。胃癌患者存在有细胞免疫及铜锌含量的异常。外周血T细胞亚群作为反映细胞免疫功能的重要指标，研究其与血清钢锌含量变化的相关性，以期为提高患者细胞免疫功能的方法提供理论依据。方法研究对象：随机选择52例胃
Cellular immune function is normal or not. It affects the occurrence and progression of the tumor and the prognosis of the patient. Patients with gastric cancer have abnormal cellular immunity and copper and zinc levels. Peripheral blood T cell subsets as an important indicator to reflect the cellular immune function, to study its correlation with the changes in serum zinc content, in order to provide a theoretical basis for improving the patient’s cellular immune function. Methods Study Object: Randomly selected 52 cases of stomach
