摘要 目的探讨Bcl—2和ki—67蛋白在星形胶质细胞反应性增生与低级别星形胶质细胞瘤中表达的区别及意义。方法应用组织芯片和免疫组化染色技术检测正常脑组织、星形胶质细胞反应性增生、低级别(I~Ⅱ级)和高级别(Ⅲ~Ⅳ级)星形胶质细胞瘤中Bcl—2和ki—67蛋白的表达情况。结果正常脑组织中两者均为阴性表达;星形胶质细胞反应性增生组中Bcl—2和ki—67阳性率分别为26.7%、22.2%;低级别星形胶质细胞瘤组中Bcl—2和ki—67阳性率分别为50.0%、70.2%;高级别星形胶质细胞瘤组中Bcl—2和ki—67阳性率分别为79.2%、95.2%。Bcl—2和ki—67在各实验组问比较均差异显著(P〈0.01);Bcl—2和ki—67表达与组织学分级密切相关(P〈0.01);Bcl—2与ki—67表达密切相关(P〈0.05)。结论Bcl—2在星形胶质细胞瘤的发生、发展中起重要作用;Bcl—2和ki—67联合应用在星形胶质细胞反应性增生与低级别星形胶质细胞瘤的鉴别诊断中可能会有一定的意义。
