文摘目的:探讨在肿瘤细胞生物治疗单个核细胞采集中,影响终产品单个核细胞计数(mononuclear cell,MNC)和采集效率(collection efficiency,CE)的因素。方法:对共计142例肿瘤患者和健康供者的采集数据进行分析,包括年龄、性别、身高、体重、身体质量指数(body mass index,BMI)、全身血容量、诊断类别、血管通路、操作者、终产品量、ACD抗凝剂用量、流速、循环次数、采前血红蛋白(Hb)、红细胞计数(RBC)、血小板计数(Plt)、白细胞计数(WBC)、淋巴细胞计数、单核细胞计数、中性粒细胞计数、去掉抗凝剂的循环血量、终产品单个核细胞计数和单个核细胞的采集效率。其中单个核细胞CE(%)=终产品MNC×100/(采前MNC×去掉抗凝剂的循环血量)。采用T检验和多元线性回归分析研究影响终产品MNC和CE的因素。结果:肿瘤患者的CE高于健康供者(24.41±1.91,20.01±0.99,P=0.043),不同操作者之间CE不同(P=0.01,H=18.59)。终产品MNC与终产品容量、ACD抗凝剂用量、采前淋巴细胞计数呈正相关(P=0.00,P=0.01,P=0.00,r=0.811);MNC的CE与流速、采前RBC计数呈负相关,与操作者工作年限、ACD抗凝剂用量呈正相关(P=0.01,P=0.04,P=0.03,P=0.00,r=0.495)。结论:采前淋巴细胞计数越高、ACD抗凝剂用量和终产品容量越多,终产品MNC越多;ACD抗凝剂用量越多,操作者资历越高单个核细胞CE越高;采前RBC越高、采集流速越快,单个核细胞CE越低。
