摘要: 目的 了解血小板减少性疾病患者外周血未成熟血小板分数(IPF)、高荧光强度未成熟血小板分数(H-IPF)、未成熟血小板绝对值(IPF#)和血小板平均侧向荧光强度(PLT-X)的变化,探讨其在血小板减少性疾病中的临床意义。 方法 选取血小板减少性疾病86例[特发性血小板减少性紫癜(ITP)50例、再生障碍性贫血(AA)15例、急性白血病(AL)21例]、骨髓增生性疾病(MPD)32例[慢性粒细胞白血病(CML)11例、原发性血小板增多症(ET)16例、真性红细胞增多症(PV)5例]和健康对照者50名。应用SYSMEX XE-5000全自动血液分析仪检测各疾病组及健康对照组外周血血小板(PLT)、IPF、H-IPF、IPF#和PLT-X。将ITP组按PLT计数结果分为0≤30×109/L、(>30~<60)×109/L、(60~<100)×109/L 3组,并比较各组IPF。  结果 ITP组IPF、H-IPF、IPF#和PLT-X测定值分别为(19.8±12.7)%、6.7(4.7~12.3)%、3.1(2.0~12.1)×109/L和(27.8±8.6)ch;AA组IPF、H-IPF、IPF#和PLT-X测定值分别为(5.6±2.5)%、1.9(0.7~4.0)%、0.8(0.4~1.4)×109/L和(17.3±2.4)ch;AL组IPF、H-IPF、IPF#和PLT-X测定值分别为(6.3±3.4)%、2.1(1.2~4.1)%、2.4(1.5~3.2)×109/L和(18.7±3.0)ch;MPD组IPF、H-IPF、IPF#和PLT-X测定值分别为(3.1±1.6)%、0.9(0.7~1.4)%、19.2(14.0~22.5)×109/L和(16.9±2.3)ch;健康对照组IPF、H-IPF、IPF#和PLT-X测定值分别为(4.1±1.3)%、1.2(1.0~1.7)%、9.3(7.4~12.1)×109/L和(18.4±1.5)ch。ITP组IPF、H-IPF和PLT-X明显高于AA组、AL组、MPD组和健康对照组(P<0.05);ITP组IPF#与AA组、AL组、MPD组比较差异均有统计学意义(P<0.05),和健康对照组比较差异无统计学意义(P>0.05)。ITP各组间IPF差异无统计学意义(P>0.05)。  结论 检测血小板相关参数(IPF、H-IPF和PLT-X)可能有助于血小板减少性疾病的鉴别诊断。

Abstract: ,Objective To investigate the variation of immature platelet fraction(IPF),high-fluorescence intensity of immature platelet fraction(H-IPF),absolute value of immature platelet(IPF#)and mean side fluorescence intensity of platelet(PLT-X)in patients with thrombocytopenic diseases and their clinical significance in the thrombocytopenic diseases.   Methods The platelet(PLT),IPF,H-IPF,IPF# and PLT-X of peripheral blood in 86 patients with thrombocytopenic diseases [50 cases of idiopathic thrombocytopenic purpura(ITP),15 cases of aplastic anemia(AA)and 21 cases of acute leukemia(AL)],32 patients with myeloproliferative disorders(MPD)[11 cases of chronic myelogenous leukemia(CML),16 cases of essential thrombocythemia(ET)and 5 cases of polycythemia vera(PV)] and 50 healthy subjects were determined by automatic hematology SYSMEX XE-5000 analyzer. According to the results of PLT,the 50 cases of ITP were classified into ≤30×109/L,(>30-<60)×109/L and(60-<100)×109/L groups,and the results for IPF were compared.  Results The IPF,H-IPF,IPF# and PLT-X in ITP group were(19.8±12.7)%,6.7(4.7-12.3)%,3.1(2.0-12.1)×109/L and(27.8±8.6)ch,respectively. The IPF,H-IPF,IPF# and PLT-X in AA group were(5.6±2.5)%,1.9(0.7~4.0)%,0.8(0.4~1.4)×109/L and(17.3±2.4)ch,respectively. The IPF,H-IPF,IPF# and PLT-X in AL group were(6.3±3.4)%,2.1(1.2~4.1)%,2.4(1.5~3.2)×109/L and(18.7±3.0)ch,respectively. The IPF,H-IPF,IPF# and PLT-X in MPD group were(3.1±1.6)%,0.9(0.7~1.4)%,19.2(14.0~22.5)×109/L and(16.9±2.3)ch,respectively. The IPF,H-IPF,IPF# and PLT-X in healthy subject group were(4.1±1.3)%,1.2(1.0~1.7)%,9.3(7.4~12.1)×109/L and(18.4±1.5)ch,respectively. Compared with the AA,AL,MPD groups and healthy subject group,the IPF,H-IPF and PLT-X of ITP group wrer higher(P<0.05),and the difference in the IPF# between ITP group and the other 3 groups was significant(P<0.05),but there was no statistical significance in the IPF# between ITP group and healthy subject group(P>0.05). There was no statistical significance for IPF in the different groups of ITP(P>0.05).
