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.     

荧光猝灭法测定冷沉淀凝血因子中的纤维蛋白原含量

目的 建立冷沉淀凝血因子中纤维蛋白原含量测定的新方法,实现纤维蛋白原含量的简单、快速、准确测定。方法 纤维蛋白原(Fib)与羊抗人纤维蛋白原(抗-Fib)能够发生特异性的结合,进而形成抗原抗体复合物。当溶液中有Fib存在时,标记有异硫氰酸荧光素(FITC)的羊抗人纤维蛋白原(FITC-抗-Fib)因免疫复合物的形成导致FITC的荧光发生猝灭。在一定浓度范围时,FITC-抗-Fib的荧光猝灭程度与Fib浓度(c_Fib)呈正相关。结果 当c_Fib为(0.007 8～0.560 0)g/L时,FITC-抗-Fib的荧光猝灭程度[(I₀-I)/I₀]与ln(c_Fib)的线性关系为(I₀-I)/I₀=15.53ln(c_Fib)+80.79 (R²=0.99);利用本法测定Fib,回收率为(96.77～102.43)%;利用本法分别测定高、中、低三个浓度的Fib,得到的日内变异系数分别为0.31%、0....

重组人骨形态发生蛋白2调节人脂肪间充质干细胞表达血管内皮生长因子

背景：重组人骨形态发生蛋白2可以促进组织工程骨血管化,但是对于其作用于人体细胞时的生物学规律不明确。目前对于重组人骨形态发生蛋白2调节人体细胞血管内皮生长因子表达的规律国内还未见相关报道。 目的：从基因和蛋白水平观察比较不同时间点重组人骨形态发生蛋白2诱导下人脂肪间充质干细胞血管内皮生长因子的表达。 方法：从成人脂肪组织中分离培养脂肪间充质干细胞,取第3代细胞用于实验,分为诱导组和对照组。诱导组采用终浓度为100 μg/L重组人骨形态发生蛋白2诱导人脂肪间充质干细胞,分别诱导3,6,12,18,24,36,48 h后收集样本,用RT-PCR和ELISA分别从基因水平和蛋白水平检测血管内皮生长因子的表达,并与空白对照组比较。 结果与结论：重组人骨形态发生蛋白2调节人脂肪间充质干细胞表达血管内皮生长因子具有时间依赖性,在不同时间点血管内皮生长因子表达量不同。与空白对照组相比,3-6 h时间段重组人骨形态发生蛋白2抑制血管内皮生长因子表达(P < 0.05),18-24 h时间段重组人骨形态发生蛋白2促进血管内皮生长因子表达(P < 0.05),当利用重组人骨形态发生蛋白2促进组织工程骨血管化时这两个时间段应当引起特别关注。     

快速浓集自体脂肪干细胞促进移植异体骨早期血管化

背景：目前可满足骨修复的组织工程骨的快速构建方法尚不成熟,植入物早期血管化仍是研究热点。 目的：将快速浓集自体脂肪干细胞直接置于植骨周围,通过正电子发射型计算机断层显像/CT直观观察其对植入异体骨的早期血管化影响,从而探索一种可用于临床的快速组织工程骨构建方法。 方法：将45只雄性新西兰大白兔随机等分为异体骨组、复合组和自体骨组,分别在腰5,6横突间植入同种异体髂骨条、同种异体髂骨条复合快速浓集自体脂肪干细胞和自体髂骨条,各组于植入后1,3,5周注射18F-NaF,通过正电子发射型计算机断层显像/CT对各组动物进行扫描显像,对比各组植骨区标准摄取值。 结果与结论：异体骨兔植骨区中段放射性分布低,血供及代谢未见明显改善,而复合快速浓集自体脂肪干细胞组植骨区18F-NaF的标准摄取值均不同程度地高于异体骨组(P < 0.05),提示快速浓集自体脂肪干细胞可促进植入骨的早期血管化,有效改善植骨区的血供和代谢,为临床快速构建组织工程骨提供了一种新思路。
