摘要: 目的:探讨肿瘤患者末梢血多形核白细胞(PMN)活性氧(ROS)强度和超氧化物歧化酶(SOD)水平与肿瘤发生、发展的关系。方法:采用流式细胞仪法及邻苯三酚自氧化法对60例肿瘤患者及60例健康体检者末梢血PMN的ROS强度、SOD活性进行检测。结果:PMN的活性氧产生肿瘤组[(387.12±2.87)MFI]明显高于对照组[(112.34±3.64)MFI](P<0.01),原发组[(493.56±3.44)MFI]高于转移组[(269.42 ±3.66)MFI](P<0.01);SOD水平肿瘤组[(218.80±4.59)U·g-1 Hb]明显低于对照组[(320.57±3.35)U·g-1  Hb](P<0.05),原发组[(189.4±2.85)U·g-1 Hb]低于转移组[(256.13±3.66)U·g-1 Hb](P<0.05)。结论:肿瘤患者存在活性氧代谢失衡,且活性氧代谢情况可能与肿瘤的不同发展阶段有关。

Abstract: Objective To study the relationship between reactive oxygen species(ROS) in polymorphonuclear granulocytes (PMN),SOD of peripheral blood and tumor′s genesis and aggression.Methods Sixty patients with cancer and sixty healthy persons were chosen. FACS and pyrogallol auto-oxidation test were used to detect ROS in PMN, SOD activity of peripheral blood. Results ROS in PMN in cancer group (387.12±2.87 MFI) was higher than that in control group (112.34±3.64 MFI) (P<0.01);ROS in PMN in primary cancer group (493.56±3.44 MFI) was higher than that in metastatic cancer group (269.42±4.10 MFI) (P<0.05); SOD level in peripheral blood in cancer group (218.80±4.59 U·g-1 Hb) was lower than that in control group (320.57±3.35 U·g-1 Hb)(P<0.05), and SOD level in peripheral blood in primary cancer group (189.41±2.85 U·g-1 Hb) was lower than that in metastatic cancer group (256.13±3.66 U·g-1 Hb) (P<0.05). Conclusion There is metabolic disturbance of ROS in patients wi th cancer and ROS may be associated with the stage of cancer.
