摘 要:目的:观察凋亡调节蛋白的表达与脑膜瘤级别、复发的关系。方法:用LSAB免疫组织化学方法对80例脑膜瘤细胞中凋亡调节蛋白BCL-2、Bax和Bcl-XL的表达进行分析。结果:恶性组BCL-2瘤蛋白阳性率(88%)明显高于良性组(37%)(P<0.05)。分别比较良性组、非典型组和恶性组中Bax、BCL-XL癌蛋白表达阳性率,无显著差异(P>0.05)。而BCL-2+BCL-XL/Bax与脑膜瘤级别有统计学相关性(P<0.01)。非复发组、复发组首次手术组、再次复发组中BCL-2、Bax和Bcl-XL癌蛋白阳性率两两比较均无显著性差异(P>0.05)。结论:BCL-2、Bax和Bcl-XL在脑膜瘤发生中起调节作用,BCL-2+BCL-XL/Bax是脑膜瘤生物学行为的有效检测法。Objective: To explore the relationship between expression of apoptosis-modulating proteins and histopathological grade and recurrence in meningioma. Methods: Immunohistochemistry method (LSAB) was used to detect the expression of BCL-2, Bax and BcI-XL, in 80 cases of meningioma including benign group (38cases), atypical group (26cases) and malignant group(16cases). 48 cases of selected whole materials were classified as recurrence (16 cases) and non-recurrence (22 cases). Results: Expression of BCL 2 oncoprotein positive in malignant group (88%) was significantly higher than benign group (37%) (P〈0.05). The expression of Bax and BCL XL oncoprotein positive in benign, atypical and maligant rneningiomas were not significant different (P〉0.05). But BCL-2+ BCL-XL/Bax was associated statistically with meningioma grade (P〈0.01). The expression of BCL-2 and Bax,BCL-XL oncoprotein positive in non-recurrent, initially resected recurrent and recurrent meningiomas, were not significant differenl (P〉0.05). Conclusion: BCL-2, Bax and Bcl-XL might play important roles in meningioma and BCL-2 + BCL-XL/Bax was useful parameters for estimating of biological behavior of meningiomas.
