【摘要】:目的通過免疫組化獲取GDF-15、ZEB1、TIP30在各級膠質瘤及正常腦組織中的表達情況,探討GDF-15、ZEB1、TIP30在膠質瘤病變的發(fā)生、發(fā)展中可能存在的關系以及可能機制,為進一步研究膠質瘤的發(fā)病機理、發(fā)生和發(fā)展提供新的研究基礎和理論依據,為膠質瘤的臨床治療提供更多的指導。方法選取1998年以來在開灤總醫(yī)院神經外科收入的69例患者術中切除的膠質瘤組織標本納入實驗組(所有標本均在液氮中保存),再選取15例腦出血切除術后的正常腦組織納入對照組。然后根據世界衛(wèi)生組織(WHO)中樞神經系統(tǒng)腫瘤的分類及分級法(2007版)將實驗組分為三亞組:第一組:I-II級膠質瘤27例;第二組:Ⅲ級膠質瘤,22例;第三組:Ⅳ級膠質瘤,20例;再把實驗組按照腫瘤大小分為兩個亞組:大于5cm組,38例,小于5cm組,31例。采用常規(guī)HE染色及免疫組化染色獲取各組GDF-15、ZEB1、TIP30的基因表達情況。最后通過SPSS 17.0中文版進行統(tǒng)計分析,陽性率組間比較用卡方檢驗,三種因子表達陽性率與膠質瘤級別之間關系用spearman等級相關分析,三種因子表達陽性率之間相關性比較用spearman等級相關分析。結果1 TIP30蛋白在對照組、膠質瘤組中總體表達陽性率分別為86.7%(13/15)、47.8%(33/69),在I-II、III、IV級組的陽性表達率分別為66.7%(18/27)、45.5%(10/22)、25.0%(5/20)。在小于5cm組、大于5cm組中的表達陽性率分別為64.5%(20/31)、34.2%(13/38)。差異有統(tǒng)計學意義(P0.05),2 GDF-15蛋白在對照組、膠質瘤組中表達陽性率分別為20.0%(3/15)、55.1%(38/69),在I-II、III、IV級組的陽性表達率分別為37.0%(10/27)、59.1%(13/22)、75%(15/20)。在大于5cm組、小于5cm組中的表達陽性率分別為65.8%(25/38)、41.9%(13/31),差異有統(tǒng)計學意義(P0.05),3 ZEB1蛋白在對照組、膠質瘤組中表達陽性率分別為6.7%(1/15)、34.7%(24/69),在I-II、III、IV級組的陽性表達率分別為14.8%(4/27)、40.9%(9/22)、55.0%(11/20)。在小于5cm組、大于5cm組中的表達陽性率分別為19.4%(6/31)、47.4%(18/38)。差異有統(tǒng)計學意義(P0.05),4 TIP30與GDF-15表達呈負相關(r=-0.261,P=0.017),ZEBI與GDF-15在膠質瘤中表達呈正相關(r=0.250,P=0.022),TIP30與ZEB1表達陽性率呈負相關(r=-0.350,P=0.001)。結論1 GDF-15、ZEB1在腦膠質瘤組中的表達陽性率明顯增高,在對照組中陽性表達率較低,提示GDF-15、ZEB1與膠質瘤有密切的關系,GDF-15、ZEB1陽性表達率隨著膠質瘤惡性級別提高而進一步增高,提示GDF-15、ZEB1與膠質瘤的惡性級別呈正相關;2 TIP30在膠質瘤組中的表達陽性率低于對照組,提示TIP30與膠質瘤之間關系密切,TIP30隨著各亞組膠質瘤惡性度提高而降低,提示TIP30與膠質瘤的惡性級別呈負相關;3 TIP30與GDF-15、ZEB1在膠質瘤中的陽性表達呈負相關,GDF-15與ZEB1在膠質瘤中的陽性表達呈正相關,提示TIP30有可能對GDF-15、ZEB1起到抑制作用,而GDF15有可能與ZEB1之間存在促進關系。

Methods 69 glioma tissue specimens collected from neurosurgery in Kailuan General Hospital since 1998 were included in the experimental group (all specimens were preserved in liquid nitrogen). Another 15 cases of normal brain tissue after intracerebral hemorrhage resection were included in the control group. Then, according to the classification and classification of (WHO) central nervous system tumors (2007 edition), the experimental group was divided into three subgroups: group 1: 27 cases of I-II grade gliomas, group 2: grade 鈪,
