摘　　要：目的探讨肺癌患者血样中硒含量的变化。方法采集肺癌组和对照组血样,用硝酸、过氧化氢混合液微波消解样品,采用原子荧光光谱法测定血样中硒的含量。结果肺癌组和对照组硒平均质量浓度分别为0.087、0.123 mg/L。结论肺癌患者血样硒含量明显降低,缺硒可能是导致肺癌高发的重要因素。Objective The paper investigates the change of the selenium content in the blood samples of patients with lung cancer. Methods The writer applies miscible liquids of nitric acid and hydrogen peroxide to the digestion of the collected blood samples from lung cancer group and the control group,using atomic fluorescence spectrometry to determine the content of selenium in blood samples. Results The average content of selenium in the lung cancer group and control group in average content of selenium are 0. 087 mg /L and 0. 123 mg /L respectively. Conclusion The content of selenium significantly lowered in the blood samples collected from patients with lung cancer. Selenium deficiency may be an important factor leading to high incidence of lung cancer.
