摘  要:[目的]探讨非小细胞肺癌(NSCLC)患者外周血中Treg和Th17细胞的变化及其意义。[方法]收集40例NSCLC患者和20名健康对照的外周血样本,采用流式细胞术检测外周血中Treg和Th17细胞占CD4+T细胞的比例,酶联免疫吸附实验法检测TGF-β和IL-17水平。[结果]肺癌患者外周血中Treg细胞和Th17细胞比例均显著性高于健康对照组(分别为6.65%±3.70%vs 4.06%±1.23%和1.20%±1.19%vs 0.44%±0.13%,P〈0.05)。外周血Treg和Th17细胞表达与NSCLC患者分期等无相关性(P〉0.05)。肺癌患者外周血TGF-β和IL-17水平明显高于对照组(分别为25.05±3.19 vs 15.96±3.65和4.36±2.79 vs 2.01±1.83,P〈0.05)。[结论]NSCLC患者外周血中Treg和Th17细胞以及相关细胞因子均高表达,Treg细胞以及Th17细胞参与了肺癌的发生和发展。[Objective] To determine the levels of Treg and Th17 cells in peripheral blood of patients with non-small cell lung cancer(NSCLC) and their significance. [Methods] The peripheral blood samples of 40 NSCLC patients and 20 health subjects were collected. The Treg and Th17 cells in peripheral blood were detected by flow cytometry,the serum TGF-β and IL-17 levels were measured by ELISA.The relationship between the expression of Treg and Th17 cells and clinicopathological features of NSCLC patients was analyzed.[Results] The expression of Treg and Th17 cells in peripheral blood of NSCLC patients were significantly higher than that in healthy controls(6.65%±3.70% vs 4.06%±1.23% and 1.20%±1.19% vs 0.44%±0.13%,both P0.05).However the levels of Treg and Th17 were not correlated with the stage of NSCLC(P0.05).The serum TGF-βand IL-17 levels in NSCLC patients were significantly higher than those in controls(25.05±3.19 vs15.96±3.65 and 4.36±2.79 vs 2.01±1.83,both P0.05). [Conclusion] Treg and Th17 cells and their associated cytokines TGF-β and IL-17 are highly expressed in peripheral blood of NSCLC patients.
