血脂在免疫相关性血细胞减少症病情评估中的作用

目的：探讨血脂水平与血细胞计数的相关性,以及血脂检测在免疫相关性血细胞减少症（IRH）病情评估中的价值。方法：选取33例免疫相关性血细胞症患者（IRH组）及30例健康人（对照组）为研究对象,检测血常规、总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL-C）和低密度脂蛋白胆固醇（LDL-C）。结果：IRH组治疗前TC、TG中位数分别5.5 mmol/L、2.5 mmol/L,分别高于对照组的4.80 mmol/L和1.09 mmol/L,差异均有统计学意义（P＜0.05）;IRH组治疗前白细胞、血红蛋白、血小板计数分别为4.3×109/L,102.85g/L和71.0×109/L,分别低于对照组的6.05×109/L,140.57 g/L和220.50×109/L,差异均有统计学意义（P＜0.05）。IRH组治疗后血红蛋白、血小板计数分别为109.06 g/L和172.0×109/L,较治疗前明显升高,差异均有统计学意义（P＜0.05）;TC、TG分别为4.60 mmol/L和1.46 mmol/L,较治疗前显著下降,差异均有统计学意义（P＜0.05）。对照组中血小板与TG存在弱相关（rs=0.431,P=0.017）,与TC、HDL-C和LDL-C无关（P＞0.05）。IRH组治疗前血小板与各项血脂指标均不具有相关性（P＞0.05）,但治疗后血小板与TG存在弱相关（rs=0.386,P=0.026）,而与TC、HDL-C及LDL-C不存在相关关系（P＞0.05）。结论：血脂水平对免疫相关性血细胞减少症患者病情评估有重要作用,高水平的TC、TG提示较为严重的病情。

X射线胸部摄影曝光剂量与图像质量相关性研究

目的 研究数字化X射线胸部高千伏摄影曝光剂量与图像质量的关系,确定数字化X射线摄影最佳曝光剂量。方法 选择胸部高千伏摄影管电压120 kV,摄影mAs从1 mAs逐档增加至25 mAs,对模拟人体胸部厚度摄影体模与CDRAD 2.0对比度细节体模进行摄影,测量体模表面X射线入射剂量,由5位观察者独立阅读体模影像,比较任意两曝光条件组之间的图像质量因子（IQF）,确定高千伏胸部摄影最佳条件。比较4和10 mAs条件下正常人体胸部摄影图像质量评分。结果 胸部高千伏摄影体模曝光条件从1 mAs增加到25 mAs,体模表面X射线入射剂量从0.067 mGy增加至1.468 mGy。随着X射线入射剂量的增加,影像质量影响因子IQF值不断减小,观察者阅读体模信号的IQF差异有统计学意义（F=31.00,P<0.05）,曝光剂量条件选择在1~4 mAs时所对应的IQF均值差异有统计学意义（F=15.3,P<0.05）,4~10 mAs时所对应的IQF差异无统计学意义,10~25 mAs时所对应的IQF均值差异有统计学意义（F=9.74,P<0.05）。曝光剂量条件选择4和10 mAs所对应的体模表面入射剂量为0.250和0.606 mGy,两种条件下胸部图像质量的综合评分分别为（24.8±1.64）、（25.8±2.05）分,差异无统计学意义。结论 随着数字化X射线摄影剂量的增加所获得图像信息量增加。满足临床诊断的标准人体胸部高千伏数字化X摄影最佳剂量为0.250 mGy左右。     

鼻底解剖特征与阻塞性睡眠呼吸暂停低通气综合征的相关性分析

目的　分析鼻底及相关上气道解剖特征与阻塞性睡眠呼吸暂停低通气综合征（obstructive sleep apnea hypopnea syndrome,OSAHS）的相关性。方法　50例OSAHS患者和40例对照组研究对象均接受多道睡眠图监测及上呼吸道三维CT检查。对比组间各参数差异,分析上气道解剖特征与睡眠监测参数间的相关性。结果　两组间多个CT指标均具有显著性的差异,包括腭咽腔与舌咽腔的最小左右径及最小截面积、腭咽腔的最小前后径以及鼻底气道宽度（P 均<0.05）。logistic回归分析提示腭咽最小截面积及鼻底气道宽度是OSAHS发生与否的独立预测因素（风险比值比分别为0.978及0.589,P <0.05）。相关分析提示鼻底气道宽度及鼻底气道面积均与多项咽腔CT指标显著相关（P <0.05）,其中二者与腭咽腔最小截面积的相关系数分别为0.536及0.425。结论　鼻底及腭咽腔狭窄是OSAHS发生的独立解剖危险因素,鼻底部位的气道特征与下游咽腔的解剖特征相关。     

典型与不典型免疫表型慢性淋巴细胞白血病的预后相关因素分析

Objective To analyze the proguostic factors for chronic lymphocytic leukemia (CLL) with typical and atypical immunophenotype. The parameters analyzed included sex, age, Binet stages, abso-lute lymphocyte count (ALC), immunoglobulin heavy-chain variable region (IgVH) gene mutation status, ZAP-70 protein, CD38 expression and cytogenetic aberrations. Methods According to the clinical guideline and scoring system for CLL in Britain, among 77 patients, 61 patients with score 5 called typical immunophe-notype CLL, 16 with score 4 or 3 were atypical immunophenotype CI,L. Multiparameter flow cytometry was employed for immunophenotypic analysis in 77 CLL patients for CD5, CD19, CD23, FMC7, slg, CD20, CD79h expression and ZAP-70 protein and CD38. IgVH mutation status was detected by multiplex RT-PCR and sequencing of the purified PCR amplification products. Fluorescence in situ hybridization (FISH) and a panel of probes were used to detect cytogenetic aberrations. Results There was no significant difference be-tween the two groups in sex, age, ZAP-70 and IgVH mutation status (P =0.398, P =0. 189, P =0.268 and P =0. 131, respectively). The incidence of ALC≥50 × 109/L, Binet B + C, CD38 ≥30% in atypical CLL patients(43.8%, 87.5% and 43.8%, respectively) were higher than that in typical group (16.4%, 36.1% and 16.4%, respectively) (P = 0. 026, P < 0. 01 and P = 0. 026, respectively). The proportion of typical patients (26. 8%) with a 13q14 deletion as sole abnormality was higher than that of atypical patients (7.6%), and that with deletion of 11q22 or 17p13 was lower than that of atypical patients (12.2% vs 46.2%) (P = 0. 022). Conclusion There were obvious differences between the typical immunophenotype CLL and atypical CLL in ALC, Binet stages, CD38 expression level and cytogenetic aberrations.
