Colony forming unit-megakaryocytes （CFU-MK） of 46 ITP patients with HCMV infection were incubated from patients＇ bone marrow mononuclear cells （MNC）. Reverse transcriptase-polymerase chain reaction （RT-PCR） was subsequently used for CFU-MK for HCMV-late mRNA detection, Ganciclovir therapy was given to both HCMV-late mRNA positive and negative groups for comparison of therapeutic effectiveness, The results in 19 of 46 CFU-MK culture cells specimens with positive HCMV-DNA by PCR or positive CMV-IgM by enzyme linked immunosorbent assay （ELISA） in the correspondent serum of peripheral blood were positive for HCMV-late mRNA, Sixteen out of 19 patients with positive HCMV-late mRNA CFU-MK had a positive response to ganciclovir. Amongst 27 patients with negative HCMV-late mRNA CFU-MK, only 4 positive responders to ganciclovir therapy were observed. Curative effectiveness of ganciclovir in HCMV-late mRNA positive group was significantly higher than that in HCMV-late mRNA negative group （P〈0.01）, It was suggested that HCMV could directly infect CFU-MK, which might be one of the mechanisms responsible for HCMV related ITE The ganci- clovir is an effective therapy in resulting in the increases in thrombocyte in the ITP patients whose HCMV- late mRNA was positive in their CFU-MK.展开更多
目的了解地塞米松(D X M)对特发性血小板减少性紫癜(ITP)骨髓涂片中巨核细胞的形态学改变。方法收集42例ITP初诊患者作为ITP组和22名健康人作为对照组,其中ITP组标本分别在大剂量D X M治疗前和治疗两周后采样,即D X M治疗前和D X M治疗...目的了解地塞米松(D X M)对特发性血小板减少性紫癜(ITP)骨髓涂片中巨核细胞的形态学改变。方法收集42例ITP初诊患者作为ITP组和22名健康人作为对照组,其中ITP组标本分别在大剂量D X M治疗前和治疗两周后采样,即D X M治疗前和D X M治疗后。然后分别采集上述分组对象的骨髓并涂片,与对照组骨髓片一并在显微镜下对巨核细胞进行分类,并记录D X M治疗前、D X M治疗后以及对照组的血小板数目。结果 D X M治疗前比值与D X M治疗后比值、对照组比值相比较,差异均具有统计学意义(P<0.01),但治疗后比值与对照组比值相比较,差异无统计学意义(P>0.05);同时,D X M治疗后外周血小板数较治疗前明显升高(P<0.01),但与对照组相比仍较低(P<0.01)。结论 D X M在治疗ITP过程中,可直接或间接促使巨核细胞凋亡,从而使血小板生成增加。展开更多
