摘要: 目的 研究环氧化合酶-2 (COX-2) 和生存素 (Survivin) 在人成釉细胞瘤 (AB) 中的表达情况。方法 收集 60 例 AB 患者的肿瘤组织和正常口腔黏膜组织。60 例 AB 患者中原发 40 例, 复发 20 例; 组织学分型: 棘皮瘤型 12 例, 滤泡型 18 例, 丛状型 18 例, 基底细胞型 6 例, 促结缔组织增生型 6 例。采用免疫组化法和蛋白质免疫印迹法检测 AB 和正常口腔黏膜中 COX-2 和 Survivin 的表达, 比较不同组织及分型的 AB 表达情况。结果 AB 中 COX-2 蛋白的阳性表达率(82.7%)高于正常口腔黏膜(10.0%), Survivin 表达阳性率(83.3%)高于正常口腔黏膜(16.7%)。AB 中 COX-2 蛋白表达水平为 0.781±0.142, 高于正常口腔黏膜组织的 0.179±0.056; Survivin 蛋白表达水平为 0.447± 0.139, 高于正常口腔黏膜组织的 0.072±0.017, 差异均有统计学意义。COX-2 与 Survivin 的表达呈正相关(r=0.778, P<0.05)。不同组织学分型 AB 中的 COX-2 和 Survivin 表达阳性率差异无统计学意义。结论 COX-2、 Survivin 在 AB 中高表达, 可能与 AB 的发生发展有关。

Abstract: Objective To investigate the expression of cyclooxygenase-2COX-2and Survivin in ameloblastoma (AB) tissues. Methods A total of 60 AB samples (primary AB 40 cases, recurrent AB 20 cases) and 60 normal oral mucosas were collected from the Affiliated Hospital of Chengde Medical College. The AB samples included 12 acanthomatous types, 18 follicular patterns, 18 plexiform patterns, 6 basal cell ameloblastomas and 6 desmoplastic ameloblastomas. The expression levels of COX-2 and Survivin were detected by immunohistochemistry and Western blot methods in AB and normal oral mucosa. The expressions of COX-2 and Survivin were compared between different types and tissues of AB. Results The positive rate of COX-2 was significantly higher in AB (82.7%) than that in normal oral mucosa (10.0%). The positive rate of Survivin was significantly higher in AB (83.3%) than that in normal oral mucosa tissues (16.7%). The expression of COX-2
(0.781±0.142) was higher in AB than that of normal oral mucosa tissues (0.179±0.056). The expression of Survivin (0.447± 0.139) was significantly higher in AB than those in normal oral mucosa tissues (0.072±0.017). There was a positive correlation between the expression of COX-2 and Survivin (r=0.778P0.05). There were no significant differences in the positive expressions of COX-2 and Survivin between different types of AB (P>0.05). Conclusion COX-2 and Survivin were overexpressed in AB, which may be involved in the occurrence and development of AB.
