摘要 目的 探讨肺癌患者手术前后自然杀伤(NK)细胞、T细胞亚群及辅助性T细胞(Th)1、2亚群细胞因子的变化.方法 应用流式细胞术对40例肺癌患者术前、术后不同时期外周血NK细胞、T淋巴细胞亚群和TH1、TH2亚群细胞因子的变化进行检测.结果 肺癌患者术后外周血T淋巴细胞亚群明显异常,CD+3、CD+4、CD+8T细胞及NK细胞均较术前降低[(52.6±4.2)%、(31.2±1.3)%、(23.8±3.5)%1,而CD+4CD+25CDlow127高调节性T细胞水平则较术前明显增高[(10.6±2.1)%].肺癌患者术后TH1亚群细胞因子较术前明显降低[(8.62±0.93)%、(6.83±1.35)%、(6.34±1.02)%],而TH2亚群细胞因子水平则较术前升高[(2.87±0.38)%、(2.87±0.76)%、(2.46±0.48)%.结论 围手术期T细胞亚群、NK细胞和Th1、Th2亚群细胞因子的监测是反映肺癌患者免疫功能变化的客观指标,对指导患者的临床治疗有重要的参考价值.
