摘　　要：目的 探讨细菌和真菌感染患者骨髓巨核细胞的形态学改变.方法 选择浙江大学医学院附属第二医院微生物培养阳性并行骨髓检查的细菌感染患者56例,真菌感染患者20例;随机选择30例排除感染,血液系统疾病和其他严重疾病者作为对照.回顾性分析细菌感染患者血小板、巨核细胞数量、功能,并对巨核细胞胞体、细胞核分叶、空泡变性、逸核进行半定量分析比较.结果 细菌感染组巨核细胞胞体、核分叶、空泡变性、逸核积分分别为2.20±0.21、2.11±0.23、0.51±0.11和0.74±0.11;真菌感染组分别为2.21±0.16、2.10±0.19、0.52±0.10、0.79±0.10;对照组分别为1.40 ±0.10、1.36±0.12、0.28±0.06和0.54±0.09,细菌感染组和对照组间比较差异有统计学意义(t值分别为14.52、12.19、9.33和6.61,p值均＜0.05),真菌感染组和对照组间比较差异有统计学意义(t值分别为16.27、12.34、7.85、6.49,p值均＜0.05).革兰阴性(g-)菌感染组巨核细胞体积、核分叶、空泡积分分别为2.29±0.20、2.22±0.26和0.57±0.10;革兰阳性(g+)菌感染组分别为2.13±0.20、2.04±0.18和0.46±0.09,两组间比较差异亦有统计学意义(t值分别为2.07、3.03和3.56,p值均＜0.05).细菌感染组巨核细胞产板功能为31.4±7.6,真菌感染组为32.4±6.4,对照组为41.3 ±5.5,细菌感染组和真菌感染组与对照组比较差异均有统计学意义(t分别为4.78和3.98,p值均＜0.05);g-菌感染组巨核细胞产板功能为28.0 ±6.7,g+菌感染组为34.4±7.2,两组间比较差异亦有统计学意义(t=2.41,p＜0.05).结论 细菌和真菌感染患者骨髓巨核细胞胞体增大、核分叶增多、空泡变性明显、逸核增多,产板功能减低,其中g-菌感染组巨核细胞的上述表现较g+菌感染组明显. abstract： objective to investigate the morphological changes of bone marrow megakaryocytes in patients with bacterial and fungal infection.methods totally 76 patients with microorganism infection fromObjective To investigate the morphological changes of bone marrow megakaryocytes in patients with bacterial and fungal infection.Methods Totally 76 patients with microorganism infection from the Second Affiliated Hospital,Zhejiang University School of Medicine from January 2008 to August 2009 were enrolled,including 56 bacteria infected patients and 20 fungal infected patients.All patients received bone marrow examinations,and were positive in microorganism culture.Thirty subjects without infection,hematological disease and other severe diseases were randomly selected as controls.The number and function of megakaryocytes were examined retrospectively, and the size, nuclear lobulation, and vacuolar degeneration of megakaryocytes were quantitative analyzed and compared among the groups.Results The size,nuclear lobulation,vacuolar degeneration,and Yat nuclear of megakaryocytes in bacterial infected group were 2.20 ±0.21,2.11 ±0.23,0.51 ±0.11 and 0.74 ±0.11 respectively,those in fungal infected group were 2.21 ±0.16,2.10 ±0.19,0.52 ±0.10 and 0.79 ±0.10 respectively;while those in control group were 1.40 ±0.10,1.36 ±0.12,0.28 ±0.06 and 0.54 ±0.09 respectively.The differences between bacterial infected group and control were of statistical significance(t values were 14.52,12.19,9.33 and 6.61 respectively,P ＜ 0.05),and the differences between fungal infected group and control were of statistical significance(t values were 16.27,12.34,7.85 and 6.49 respectively,P ＜ 0.05).The size,nuclear lobulation,and vacuoles of megakaryocytes in gram-negative(G-)bacteria group were 2.29 ±0.20,2.22 ±0.26 and 0.57 ±0.10,while those in the gram-positive(G+)bacteria group were 2.13 ±0.20,2.04 ±0.18 and 0.46 ±0.09,and the differences were also significant(t values were 2.07,3.03and 3.56 respectively,P ＜ 0.05).The production of platelet by megakaryocytes in bacterial infected group,in fungal infected and the control were 31.4 ±7.6,32.4 ±6.4 and 41.3 ±5.5,and the differences between bacterial infected group and con
