测定食管癌患者血液中与自由基反应有关的微量元素 (Se,Cu,Zn,Mn,Cd)、维生素、超氧化物歧化酶、谷胱苷肽过氧化酶、丙二醛等 13种生化指标 ,并进行因子分析 ,建立因子对变量的回归方程 ,选取主因子 F1,F2的得分值作二维平面图 ,结果显示 :食管癌患者与对照组有明显分区 ,判别准确率为 95.3% .分析结果可作为食管癌的辅助诊断方法 .
To determine the 13 biochemical parameters of trace elements (Se, Cu, Zn, Mn, Cd), vitamins, superoxide dismutase, glutathione peroxidase and malondialdehyde in the blood of esophageal cancer patients , And factor analysis, the establishment of the regression equation of the factors on variables, select the main factor F1, F2 scores for two-dimensional plan, the results showed: esophageal cancer patients and the control group were significantly zoning, the accuracy rate of 95.3%. The results can be used as an auxiliary diagnosis of esophageal cancer.
