摘要 目的:探讨活化的造血免疫细胞回输对高剂量化疗患者的免疫保护作用。方法:经过3~6个疗程的常规化疗或常规放疗未完全缓解或缓解后复发的恶性肿瘤26例,随机分为造血免疫细胞活化组(简称活化组)16例和未活化组10例。活化组患者化疗前用GMCSF动员5 d后,从外周血分离出单个核细胞,用GMCSF、抗肿瘤抗T细胞双功能抗体、IL2在体外活化和扩增粒系祖细胞和免疫细胞,在亚去髓性化疗后回输给患者。结果:(1)与未活化组相比,活化组患者的中性粒细胞绝对数(ANC)从<0.1×109/L升至>0.5×109/L的时间缩短6.1 d;(2)体外培养CFU-GM增加9.8倍,有核细胞数增加3.4倍;(3)T淋巴细胞对抵抗NK活性的肺癌细胞株PC 84045的杀伤率从10%提高至55%,对K 562细胞杀伤率从28%提高至46%。结论:用活化的造血免疫细胞回输能加快高剂量化疗后造血和免疫功能的重建。关键词 高剂量化疗;造血细胞活化;免疫细胞活化;恶性肿瘤;治疗

Abstract Objective:To investigate the immunoprotection of patients with makignancy receiving highdose chemotherapy by activated immunohematopoietic cekk infusion.Methods:Twentysix patients with makignancy,whose responses were incompkete remission or rekapse after chemotherapy or radiotherapy for 36 courses,were randomky divided into infusion group(16 cases)and noninfusion group(10 cases).In infusion group ......
