摘要
目的:研究人脑胶质瘤巢蛋白(nestin)和CD34表达与预后的关系。方法:采用免疫组化方法检测63例人脑胶质瘤中的nestin、CD34的表达情况,并将结果与临床预后随访结果进行综合分析。结果:nestin总阳性表达率为71.4%,其中强表达16例(25.4%),中度表达14例(22.2%),弱表达15例(23.8%),不表达18例(28.6%),统计有显著性差异(P〈0.01)。nestin表达水平与胶质瘤恶性程度相关(x2=41.44,P〈0.01)。胶质瘤I级、Ⅱ级、Ⅲ级-Ⅳ级CD34标记的平均微血管密度(microvesselsdensity,MVD)分别为(35±14)、(69±33)、(119±49)个,具有显著性差异(P〈0.01)。CD34表达与nestin表达水平相关(P〈0.01)。nestin表达与生存时间负相关(P〈0.01)。结论:CD34和nestin表达有一定相关性,CD34与脑胶质瘤新生血管生成有关。CD34、nestin联合检测可准确判断患者的预后。
Objective: We investigated the expressions of nestin and CD34 in human glioma and their correlations with prognosis. Methods: Immunohistochemistry assay was conducted on the expressions ofnestin and CD34 in 63 specimens of human gliomas. We also analyzed the influence of nestin expression on survival rate. Results: Strong expressions of nestin were observed in 16 of the 63 cases (25.4%). Moderate expressions were observed in 14 cases (22.2%) and weak expressions in 15 cases (23.8%). No expressions were found in the remaining 18 cases (28.6%). Statistically significant differences existed among these groups (P〈0.01). The expression of nestin increased with higher pathological grades (x2=41.44; P〈0.01). The microvessel densities of positive CD34 cells were 35 ±14, 69 ±33, 119± 49 for grade I, II, and II - IV gliomas, respectively. Statistically significant differences existed among these groups (P〈0.01). CD34 and survival time were significantly and negatively correlated with the expression level of nestin (P〈0.01), respectively. Conclusion: The expressions of CD34 have definite correlations with nestin. CD34 is correlated with the formation ofneo-vessels in gliomas. The expressions of nestin and CD34 can be used for accurately assessing the prognosis of glioma patients.
