摘要 目的检测骨髓增生异常综合征(MDS)和再生障碍性贫血(AA)患者骨髓原始细胞免疫表型特征,探讨其对二者发病机制、诊断、分型诊断及鉴别诊断的临床意义。方法选用多种单克隆抗体,应用直接免疫荧光法、流式细胞术和CD45/SSC设门,对MDS组23例、AA组14例、正常对照组9例的骨髓原始细胞各免疫标志的表达率进行检测。结果MDS组与正常对照组相比其造血干/祖细胞抗原CD34、HLA-DR、髓系早期抗原CD13、CD33、单核系抗原CD14、T淋巴细胞抗原CD7的表达率增高,髓系成熟抗原CD15、B淋巴系抗原CD19、CD20的表达率降低,DI值增高(P<0.05);RAEB组与RA组相比CD34、HLA-DR、CD13、CD33、CD14、CD7的表达率增高,CD15、CD3、CD19、CD20的表达率减低,DI值增高(P<0.05)。AA组与正常对照组相比其CD34、CD13、CD33、CD15的表达率降低,CD3、CD7、CD25、CD22的表达率增高(P<0.05)。MDS组与AA组相比其CD34、HLA-DR、CD13、CD33、CD14的表达率增高,CD3、CD5、CD7、CD15、CD19、CD20、CD22、CD25的表达率显著降低(P<0.05)。结论MDS和AA患者骨髓细胞免疫表型分析,有助于揭示二者的发病机制,为临床提供新的诊断、分型及鉴别诊断方法。 Objective To explore the role of immunophenotyping in the pathogenesis,diagnosis,classification and differential diagnosis of myelodysplastic syndrome(MDS) and aplastic anemia(AA).Methods A panel of monoclonal antibodies and flow cytometry using CD45/SSC gating strategies were used for immunophenotyping in bone marrow nucleated cells of 23 patients with MDS,14 patients with AA and 9 healthy controls.Results Compared with the control group,expressions of haemopoietic stem/progenitor cell surface markers CD34...
