目的:了解巨幼细胞性贫血患者骨髓及实验室检查结果。方法:对222例巨幼细胞性贫血患者的骨髓象及血液的红细胞、白细胞、血小板和血清叶酸、维生素B12等结果进行总结分析。结果:有129例(58.1%)表现为全血细胞减少,以叶酸缺乏为主185例(83.3%)。叶酸、维生素B12缺乏越严重,骨髓中巨变等病态造血越明显。结论:巨幼细胞性贫血患者骨髓造血病态的程度往往反映患者营养不良的程度。 Objective: To understand the bone marrow and laboratory findings of patients with megaloblastic anemia. Methods: The bone marrow of 222 patients with megaloblastic anemia and blood red blood cells, white blood cells, platelets and serum folic acid, vitamin B12 and other results were analyzed. Results: 129 cases (58.1%) showed pancytopenia, the main folate deficiency 185 cases (83.3%). Folic acid, vitamin B12 the more serious lack of bone marrow changes in the pathogenesis of the more obvious morbidity. Conclusion: The degree of bone marrow hematopoietic disease in patients with megaloblastic anemia often reflects the degree of malnutrition in patients.
