摘要 目的:探讨不同治疗方式对恶性胆汁淤积性黄疸患者外周血自然杀伤(na-ture killer,NK)细胞的数目和功能的影响。方法:30例胆汁淤积性黄疸住院患者,按随机数字表随机分为引流组(15例)与根治组(15例),选取同期8名体检正常人群作为正常对照组。采用流式细胞术检测引流组和根治组患者治疗前及治疗后第7、13日,对照组单次外周血NK细胞占外周血总淋巴细胞比例(NK细胞比例)及perforin阳性细胞占NK细胞的比例(perforin阳性细胞比例)。结果:胆汁淤积性黄疸患者治疗前外周血NK细胞比例及perforin阳性细胞比例均低于正常对照组(均为P<0.05)。与治疗前比较,引流组与根治组治疗后第7、13日,NK细胞比例及perforin阳性细胞比例明显上升(P<0.05~0.01)。治疗后第13日,根治组的NK细胞比例及perforin阳性细胞比例明显高于引流组(P<0.05)。结论:未经治疗的恶性胆汁淤积性黄疸患者外周血NK细胞比例及perforin阳性细胞比例较正常人降低。胆道引流或根治手术切除肿瘤都可以提高该病患者的NK细胞比例及perforin阳性细胞比例,以根治手术的改善效果较为明显。
