1、·416·实用肝脏病杂志2013年l0月第16卷第5期JClinHepatol,Oct.2013.Vo1.16No.5·肝肿瘤·原发性肝癌患者射频消融治疗前后外周血T细胞亚群及NK细胞的变化邓俊陈卫陆忠华周颜【摘要】目的观察原发性肝癌患者射频消融(RFA)治疗前后T细胞亚群及NK细胞的变化。方法23例原发性肝癌患者接受RFA治疗;采用流式细胞仪检测患者和23例健康体检人群外周血CD3q'细胞、CD4~T细胞、CD4+/CD8*、CTL细胞及NK细胞水平。结果原发性肝癌患者CD3+T细胞、CD4q"细胞、CTL细胞、NK细胞的比例及CD4+/CD8比值
2、分别为61.94-13.8%、33.34-5.0%、10.34-4.9%、4.44-1.3%和1.44-0.6,均显著低于健康人群(75.74-12.3%、41.14-10.1%、19.74-5.8%、16.74-8.2%、1.74-0.6,P<0.05);CD8q"细胞的比例为25.54-5.1%,高于健康人(21.74-6.7%,P<0.05);RFA治疗后1周和2周,CD3q'细胞(72.14-9.8%、73.34-7.3%)、CD4q"细胞(39.64-10.9%、39.04-10.0%)、CTL细胞(14.84-9.6%、12.34-7.4
3、%)、NK细胞(11.14-4.9%、12.84-8.1%)均较治疗前上升,而CD8+T细胞(22.6士5.8%、22.04-9.6%)EL例下降,CD4~/CD8+比值(1.74-0.8、1.94-0.4)上升,差异均有统计学意义(P<0105)。结论原发性肝癌患者大多处于免疫抑制状态,RFA治疗可调节其T细胞亚群的平衡,升高NK细胞水平。【关键词】原发性肝癌;射频消融术;T淋巴细胞亚群;自然杀伤细胞doi:10.39690.issn.167275069.2013.05.010ChangesinperipheralT—‘celsubsetsandn
