为了探讨肺癌发生时人体内硒水平变化的机制及生物学意义,本文分析了肺癌患者血、发和肺硒水平与肺癌某些临床特征的关系。经病理学检查确诊的原发性肺癌患者,采集肺癌病人血、发样132份,癌旁肺组织72个,肺癌组织68个。用荧光法分析上述样品的硒含量。单因素分析表明,肺癌的转移距离对癌、肺、发和血硒水平均无影响。肺癌的分化程度不影响发,肺 In order to investigate the mechanism and biological significance of changes in selenium levels in humans at the time of lung cancer development, this paper analyzed the relationship between serum selenium levels in lung cancer patients and some clinical features of lung cancer. In patients with primary lung cancer diagnosed by pathological examination, 132 blood and hair samples were collected from lung cancer patients, 72 para-tumor lung tissues, and 68 lung cancer tissues. The selenium content of the above sample was analyzed by fluorescence. Univariate analysis showed that lung cancer metastasis distance has no effect on cancer, lung, hair and blood selenium levels. Lung cancer differentiation does not affect hair, lung
