目的:探讨脑胶质瘤中Survivin和Fhit的表达与细胞凋亡的相关性。方法:取90例术前无放化疗
史的脑胶质瘤手术标本和10例正常脑组织标本,利用组织阵列仪制成组织芯片,采用免疫组织化学s-p法分
别检测Survivin和Fhit的表达;并应用TUNEL技术进行细胞凋亡指数的检测。结果:在脑胶质瘤中Suvvivin
蛋白阳性率为61%,明显高于对照组(0.0%)(χ2=11.22,P<0.001),其表达率随着肿瘤级别的增高而表达增
强。Fhit蛋白的阳性率为51.1%,明显低于对照组(100%)(χ2=6.859,P<0.01),其表达率随着肿瘤级别的增
高而表达减弱(χ2=6.859,P<0.01)。应用TUNEL技术进行细胞凋亡指数的检测,脑胶质瘤中Survivin阳性
组凋亡指数明显低于阴性组P<0.01),Survivin蛋白的表达与凋亡指数呈负相关。Fhit阳性组凋亡指数明显高
于阴性组(P<0.01),Fhit蛋白的表达与凋亡指数呈正相关。结论:Suvivin和Fhit均参与细胞周期调控和细胞
凋亡,两者生物学效应相反。二者联合检测可为进一步研究脑胶质瘤提供理论依据。

[Abstract]
Objective:To explore expression of Survivin and Fhit and their roles in apoptosis
microarray.Methods:The tissue chip,which were made by tissue arrayer,composed tissue from
90cases of glioma carcinoma without history of chemo or radiation therapy and 10normal brain
tissue as control subject.Immunohistochemistry and TUNEL were employed to determine the
expression of Survivin、Fhit and apoptosis index.Results:The positive rate of Survivin in glioma
was 61%,which was much higher than control tissue(0.0%)(χ2=11.22,P<0.01).The
protein expression of Survivin in glioma was positive correlation with malignancy grade of glioma.
The positive rate of Fhit in glioma was 51.1%,which was much lower than control tissue
(100%)(χ2=6.859,P<0.01).The protein expression of Fhit in glioma was decreased in high
-grade glioma(χ2=6.859,P<0.01).The results obtained from TUNEL showed that apoptosis
index in glioma cells with positive Survivin was lower than that with negative Survivin(P<
0.01).The expression of Survivin was negatively relatived to apoptosis index.Conclusions:Sur-vivin and Fhit all take part in cell cycle control,cell apoptosis and the biologic process of glioma
cells,however they act as opposite biological effects.Combined derection of Survivin and Fhit
may offer a neccssary theory evidence in the further study of glioma.
