摘要 目的探讨维吾尔族急性早幼粒细胞白血病(APL)患者的免疫表型特征。方法 39例维吾尔族APL患者,按FAB和我国标准诊断为M3a者35例,M3b者4例。起病时外周血WBC≤10×109/L者22例(中低危组),WBC>10×109/L者17例(高危组)。抽取患者骨髓置于EDTA抗凝管,采用四色流式细胞术检测胞膜/胞质抗原,分析免疫表型。结果 39例维吾尔族APL患者细胞均表达髓系特异性抗原CD13CD33、CD38,CD34和HLA-DR阳性表达率分别为7.7%和15.4%,CD56、CD15、CD2阳性表达率分别为7.7%、30.8%、0。按CD34和HLA-DR的表达强度,将39例APL患者分成CD+34或HLA-DR+(6/39,15.4%)、CD34-和HLA-DR-(33/39,84.6%)两组,两组间CD56阳性率为分别为50%、0(P<0.05)。中低危组、高危组CD15阳性率分别为50%、5.9%(P<0.005)。结论维吾尔族APL患者的免疫表型特征为CD34、HLA-DR多阴性,CD13CD33高表达,而CD56、CD2低表达,CD15表达偏高。
