[摘要] 目的 探讨幼年型粒单核细胞白血病(JMML)实验室诊断和临床特征对提高确诊率的意义。 方法 对血液科住院患者进行骨髓穿刺及外周血象实验室检测和临床资料分析。 结果 幼年型粒单核细胞白血病实验室诊断外周血象检测指标与正常对照组比较，除ReT(‰)与对照组比较差异无统计学意义(P>0.05)，其他检测指标与正常对照组比较差异有统计学意义(P<0.01)。临床特征分析以发热、肝脾肿大、淋巴结肿大、皮肤浸润为主要表现。结论 幼年型粒单核细胞白血病实验室诊断和临床特征分析相结合对明确诊断是重要的。

    [Abstract] Objective To investigate the significance of juvenile myelomonocytic leukemia (JMML) laboratory diagnosis and clinical characteristics in improving the diagnosis rate. Methods The inpatients in the department of hematology received bone marrow aspiration and peripheral hemogram examination for laboratory testing and clinical data analysis. Results The laboratory diagnosis and peripheral hemogram detection indexes in juvenile myelomonocytic leukemia and the normal control group were compared. There was no significant difference in ReT(‰) (P>0.05) of the research group and the control group. The differences in other detection indexes of the research group and the control group were statistically significant(P<0.01). The main manifestations of clinical characteristics were fever ......
