骨髓活组织检查在慢性粒-单核细胞白血病中的诊断意义

目的评价骨髓活检在慢性粒-单核细胞白血病（CMML）中的诊断价值。方法观察42例CMML病人的骨髓涂片与骨髓活检切片，并做出比较和分析。结果骨髓涂片与切片相互结合起到相互补充的作用。结论骨髓切片与涂片结合起来更能提高CMML的检出率。     

Bone marrow histological findings in systemic lupus erythematosus with hematologic abnormalities: a clinicopathological study

BACKGROUND: The histopathologic features characterizing the involvement of the bone marrow (BM) in systemic lupus erythematosus (SLE) have not been systematically analyzed to date. OBJECTIVES: The aim of this study was to assess morphologic and immunohistochemical characteristics of BM involvement in SLE. PATIENTS AND METHODS: Clinical and serological data of 40 SLE patients with unexplained cytopenias were studied. Ten patients with myelodysplasia of refractory anemia (RA) were used as controls. BM aspiration, BM biopsy (BMB), and immunohistochemistry were carried out in patients and controls. BM fibrosis, BM necrosis, stromal edema, and abnormal localization of immature precursors (ALIP) were assessed according to standard criteria. RESULTS: Dyserythropoiesis and megakaryocytic atypias were uniform findings in SLE patients. The disruption of the normal BM architecture was a predominant SLE BM feature affecting cells of all three hemopoietic lineages, with both erythroid and megakaryocytic precursors tending to assume paratrabecular locations and ALIP aggregates being present in 27 cases. In addition, BM was hypocellular in 23 cases. BM necrotic alterations were evident in 90% of the cases. The density of reticulin content was generally increased. Vascular changes including dilatation of sinuses were manifest and were associated with the presence of necrotic alterations (P = 0.008). Hemoglobin levels correlated inversely with the presence of ALIP (P = 0.016). Upon comparing BMB features between SLE and RA controls there were striking similarities. CONCLUSIONS: BMB in patients with SLE and unexplained cytopenias presents a variety of histopathologic findings including BM necrosis, stromal alterations, hypocellularity, dyspoiesis, and distortion of normal BM architecture, characterized primarily by the presence of ALIP aggregates.     

骨髓增生异常综合征患者舌象与骨髓象相关性研究

目的:比较骨髓增生异常综合征(myelodysplastic syndromes,MDS)患者不同舌象下的骨髓象差异,探索其舌象与骨髓象的相关性及舌象的MDS预后评估价值.方法:回顾325例住院第一诊断为MDS的患者病历资料,收集并记录入组MDS患者的舌象资料(舌色、舌体、苔色、苔质、舌苔干腻情况)及骨髓检查资料(原粒...     

骨髓增生异常综合征40例病理观察分析

目的观察分析骨髓增生异常综合征(MDS)的骨髓病理表现。方法采用骨髓活检方法取髂后上棘骨髓组织40例,进行固定、脱钙、石蜡包埋、切片、HE染色,观察骨髓增生程度,红细胞(红系)、粒细胞(粒系)、巨核细胞(巨核系)三系髓细胞及间质的病理改变。结果骨髓增生极度活跃30%,明显活跃42.5%,增生活跃7.5%,增生减低20%;三系病态造血是红系67.5%,粒系62.5%,巨核系85%;95%骨髓可见幼稚前体细胞异常定位(ALIP)现象;间质改变17.5%;MDS合并骨髓纤维化3例(7.5%)。结论骨髓细胞的病态造血是MDS诊断的主要依据;ALIP现象和小巨核细胞出现是MDS诊断的重要依据;骨髓活检对MDS的诊断及判断预后具有重要意义。
