网织红细胞参数在急性白血病化疗中的应用价值

目的研究急性白血病化疗前后网织红细胞参数变化的临床意义。方法 32例急性白血病化疗的患者,化疗后好转。用自动化血液分析仪Sysmex 2000检测患者的网织红细胞比率(RET%)、网织红细胞绝对值((RET#)、低荧光强度的网织红细胞(LFR)、中荧光强度的网织红细胞(MFR)、高荧光强度的网织红细胞(HFR)、白细胞(WBC)、中性粒细胞绝对值(ANC)以及未成熟网织红细胞比率(IRF)。结果急性白血病化疗患者IRF、MFR、HFR化疗后一直减低,化疗第7天降到最低,在化疗第14天开始恢复,化疗第21天恢复至化疗前水平。LFR于化疗第7天开始升高,化疗14d开始降低,WBC和网织红细胞绝对值计数于化疗第7、14天一直降低,化疗21d开始恢复。结论 IRF、MFR、HFR、LFR是反应骨髓恢复的敏感指标,较WBC和网织红细胞的绝对值早7d。

Application value of reticulocyte parameters in chemotheraphy of acute leukemia

Objective To study the clinical significance of reticulocyte parameters change before and after chemotheraphy in acute leukemia.Methods Thirty-two chemotherapeutic patients suffered from acute leukemia were improved after chemotherapy.The percentage of reticulocyte(RET%),reticulocyte absolute value(RET#),low fluorescent reticulocyte percentage(LFR),middle fluorescent reticulocyte percentage(MRF),high fluorescent reticulocyte percentage(HFR),white blood cells(WBC) and absolute neutrophils count (ANC) and immature reticulocyte fraction(IRF) were detected by using the Sysmex 2000 automatic blood cell analyzer.Results IRF,MFR and HFR after chemotherapy in the patients with leukemia were always declined,reached the lowest on 7 d of chemotherapy,began to recover on 14 d after chemotherapy,and recovered to the level before chemotherapy on 21 d of chemotherapy.LFR began to increase on 7 d of chemotherapy,and began to decrease on 14 d of chemotherapy.WBC and RET# were always decreased on 7,14 d of chemotherapy,and began to recover on 21 d of chemotherapy.Conclusion IRF,MFR,HFR and LFR are the sensitive indicators reflecting the bone marrow recovery and are earlier than WBC and RET# by 7 d.
