慢性髓细胞性白血病与血管生成因子关系

Relationship of chronic myelocytic leukemia and angiogenesis factors

目的 :了解血管生成因子在慢性髓细胞性白血病 (CML)患者中的分泌和基因表达 ,初步探讨血管生成在CML发病和发展中的作用。方法 :用ELISA方法检测CML患者和对照组外周血血管内皮细胞生长因子 (VEGF)浓度 ,取骨髓组织活检 ,用CD34单抗标记检测骨髓微血管密度 (MVD) ,同时取外周血和骨髓细胞 ,采用RT PCR法检测VEGF、b FGF基因表达。结果 :研究组外周血VEGF浓度 (177.5 3± 15 3.4 5pg/ml)明显高于对照组 (73.12± 19.82pg/ml) (P <0 .0 5 ) ,差别有统计学意义。骨髓细胞和外周血RT PCR检测结果基本吻合 ,没有受到骨髓中其他细胞的干扰。研究组VEGF和b FGF基因高表达 (P <0 .0 5 ) ,两组差别有统计学意义。结论 :CML与血管生成之间存在着明显的关系 。

Purpose:To study the secretion and gene expression of Angiogenesis factors in the patients with CML and study the effect of Angiogenesis in the occurrence and development of CML. Methods:Concentration of VEGF in peripheral blood was determined by using ELISA. Myeloid tissue was extracted from all CML cases and ITP patients to detect MVD by using CD34 labelling. At the same time the level of VEGF,b-FGF were detected by using RT-PCR in both peripheral blood and myeloid cells.Results:Our results showed that the concentration of VEGF was obviously higher in the peripheral blood of CML patients(177.53±153.45 pg/ml) than in those of control group(73.12±19.82 pg/ml). The gene expression of VEGF and b-FGF were both higher than those of control group. The difference has statistical significance(P<0.05).Conclusions:We can demonstrate a marked relation between CML and angiogenesis.Anti-angiogenesis therapy maybe an effective method to treat CML.[
