【摘要】 为了探讨垂体肿瘤转化基因(PTTG)与碱性成纤维细胞生长因子(bFGF)在急性白血病中的表达及其与急性白血病预后的相关性,采用免疫细胞化学染色方法检测53例急性白血病患者及15例非急性白血病患者的PTTG蛋白和bFGF的表达水平。结果表明,急性白血病组PTTG蛋白和bFGF表达较非急性白血病组明显升高,两者呈显著性差异(P<0.01)。在急性白血病组中,化疗后完全缓解的患者与初发的病人比较有显著差异(P<0.01),并且PTTG蛋白和bFGF的表达呈正相关(r=0.61,P<0.01)。结论:PTTG蛋白和bFGF在急性白血病中高表达,而且与化疗疗效密切相关,这提示PTTG蛋白与bFGF的检测对于急性白血病的诊断、疗效评价及预后估计均有一定意义,PTTG与bFGF参与了急性白血病的发展。更多还原

【Abstract】 To investigate the expression of pituitary tumor-transforming gene(PTTG) and basic fibroblast growth factor (b-FGF) in acute leukemia , as well as the relationship of their expression with prognosis in acute leukemia, expressions of PTTG and b-FGF in acute leukemia (AL) specimens were detected by immunocytochemical technique. The results showed that the expressions of PTTG and b-FGF in AL group were higher than that in the control group significantly (P<0.01). In AL group, after chemotherapy, the expression of PTTG and b-FGF in de novo patients group was higher than in the complete remission patient group significantly (P<0.01). The expressions of PTTG and b-FGF showed positive correlation (r=0.61, P<0.01). It is concluded that Up-regulation of PTTG and b-FGF expression may be involved in the progression of acute leukemia and correlated closely with therapeutic effect. Associated detection of PTTG and b-FGF may help to judge the malignancy degree and prognosis of acute leukemia.更多还原
