摘要
本研究观察骨髓增生异常综合征(MDS),主要是难治性贫血(RA)骨髓及外周血细胞形态学特点,并与其它贫血性疾病(慢性再生障碍性贫血、溶血性贫血、巨幼细胞性贫血)进行比较分析。取患者骨髓及外周血制成涂片行瑞氏染色,骨髓分类500个有核细胞,外周血分类100个有核细胞,观察红系、粒系、巨核系病态细胞特点。结果发现,外周血中性分叶核细胞浆内颗粒稀少或缺如、Pelger核异常改变、幼粒细胞数及检出率、单核细胞检出率以及骨髓粒系各阶段细胞出现颗粒缺如,红系奇数核、核出芽,巨核系小巨核及单圆核巨核细胞等在RA与慢性再生障碍性贫血、溶血性贫血、巨幼细胞性贫血比较均有显著性差异(P<0.05)。结论:细胞形态学是MDS诊断的基础,外周血及骨髓细胞形态学异常在MDS与其他贫血性疾病的鉴别诊断中具有重要作用。
This study was purposed to investigate the cell morphological features of bone marrow and peripheral blood in patients with myelodysplastic syndrome, mainly with refractory anemia, and to compare them with other anemia diseases including chronic aplastic anemia, hemolytic anemia and megaloblastic anemia. The bone marrow and peripheral blood were taken from patients for preparing the smears with Wright staining. 500 karyocytes in bone marrow and 100 karyocytes in peripheral blood were detected, and the features of morbid cells of erythrocyte, granulocyte and megakaryocytic series were observed. The results showed that differences between refractory anemia, chronic aplastic anemias and hemolytic anemia as well as megaloblastic anemia were statistically significant （ P 〈 0.05 ） in the granules scarce and absence in the intracytoplasm of segmented neutrocyte in peripheral blood, Pelger dyskaryosis, the numbers and detected rate of immature granulocytes, monoeyte detected rate, the granules scarce in all stage of granulocytic series in bone marrow, odd number and prolification of nucleolus in erythrocytic series, little macronucleus and single circle nucleus macronucleus. It is concluded that cell morphology is the foundation of diagnosing the MDS, the abnormality morphology both in peripheral blood and bone marrow play the consequence role in the diagnosis of MDS.
