摘要: 目的 探討垂體腫瘤轉化基因 1( PTTG1) 和神經膠質瘤相關癌基因 1( Gli1) 在腦膜瘤中的表達水平及其與患者臨床病理特征和預后的關系。方法 選擇 2010 年 10 月至 2014 年 7 月神經外科確診的腦膜瘤患者 98 例,同期選擇 72 例腦膜瘤癌旁組織作為對照組,采用酶聯免疫吸附法測定腦膜瘤組織及癌旁組織 PTTG1、Gli1 蛋白含量、免疫組化法測定 PTTG1、Gli1 蛋白在腦膜瘤組織及癌旁組織中的表達,分析 PTTG1、Gli1 蛋白的表達情況與腦膜瘤患者臨床病理特征及腦膜瘤患者預后的關系。結果 腦膜瘤組織 PTTG1、Gli1 蛋白水平高于癌旁組織,差異均有統計學意義( t = 13. 474、14. 859,P < 0. 01) ; 腦膜瘤組織 PTTG1、Gli1 陽性率高于癌旁組織,差異有統計學意義 ( P < 0. 01) ; 腦膜瘤組織 PTTG1、Gli1 蛋白表達水平不同年齡間比較差異無統計學意義( P > 0. 05) ; 不同病理學分級、TNM 分期、浸潤深度及有無淋巴血管間隙浸潤和淋巴結轉移者的 PTTG1、Gli1 蛋白表達差異有統計學意義( P < 0. 05) ; PTTG1、Gli1 陰性組 3 年生存率及生存期均明顯高于 PTTG1、Gli1 陽性組,差異有統計學意義( χ2 =
14. 654、13. 875,t = 13. 097、12. 982,P < 0. 05) 。結論 PTTG1、Gli1 蛋白在腦膜瘤組織的表達量高于癌旁組織,PT-
TG1、Gli1 蛋白在腦膜瘤的發生發展過程中起促進作用; PTTG1、Gli1 蛋白陰性表達者能獲得較好的預后。

Abstract: Objective To investigate the expression levels of pituitary tumor transforming gene 1 ( PTTG1) and glioma related oncogene 1( Gli1) in meningioma and the clinical significance. Methods The meningioma tissues of 98 patients with meningioma who were diagnosed as meningioma in neurosurgery department of Second Affiliated Hospital of Hainan Medical University from October 2010 to July 2014 and 72 cases of para-cancerous tissues ( control group) at the same period were selected. Enzyme linked immunosorbent assay ( ELISA) was used to detect contents of PTTG1 and Gli1 proteins in meningioma tissues and para-cancerous tissues. Immunohistochemical method was used to detect the expressions of PTTG1 and Gli1 proteins. The associations of the expressions of PTTG1 and Gli1 proteins and the clinicopathological features and prognosis of meningioma patients were analyzed. Results The PTTG1 and Gli1 proteins contents in meningioma tissues were significantly higher than those in para-cancerous tissues ( t = 13. 474,14. 859,P < 0. 05 ) . The positive expression rates of PTTG1 and Gli1 proteins in meningioma tissues were significantly higher than those in para- cancerous tissue ( χ2 = 25. 847,27. 399,P < 0. 05) . There were no significant differences in expressions of PTTG1 and Gli1 proteins among different age groups( all P > 0. 05 ) . There were significant differences in the expressions of PTTG1 and Gli1proteins for different pathological grading,different TMN staging,different depth of invasion,with or without lymph- vascular space invasion and with or without lymph node metastasis( all P < 0. 05) . The 3-year survival rate and survival period in PTTG1 and Gli1-negative groups were significantly higher than those in PTTG1 and Gli1-positive groups( χ2 =
14. 654,13. 875,t = 13. 097,12. 982; all P < 0. 05) . Conclusion The expression levels of PTTG1 and Gli1 proteins in meningioma tissues are higher than those in para-cancerous tissues which suggests that PTTG1 and Gli1 proteins play a promoting role in the occurrence and development of meningioma,and PTTG1 and Gli1 proteins negative expressions can achieve better prognosis.
