1、山西醫(yī)科大學(xué)碩士學(xué)位論文Fascin和MVD的表達(dá)與垂體腺瘤侵襲性的關(guān)系中文摘要目的檢測Fascin及MVD在侵襲性和非侵襲性垂體腺瘤中的表達(dá),探討其與垂體腺瘤侵襲性的關(guān)系及它們之間的相關(guān)性。方法1.選取垂體腺瘤手術(shù)標(biāo)本45例(包括侵襲性垂體腺瘤24例和非侵襲性垂體腺瘤21例)。全部組織經(jīng)10%福爾馬林固定,常規(guī)脫水后石蠟包埋,連續(xù)切片。2.采用免疫組化Envision法檢測Fascin在侵襲性垂體腺瘤、非侵襲性垂體腺瘤中的表達(dá)水平,測定垂體腺瘤組織MVD。3.統(tǒng)計(jì)學(xué)分析兩組之間Fasicn蛋白的表達(dá)、MVD計(jì)數(shù)的差異,以及侵襲性垂體腺瘤中Fascin
2、的表達(dá)與MVD計(jì)數(shù)之間的相關(guān)關(guān)系。結(jié)果1.在24例侵襲性垂體腺瘤中,F(xiàn)ascin陽性表達(dá)18例,占75.0%,而在21例非侵襲性垂體腺瘤中Fascin表達(dá)陽性者為9例,占42.9%,兩組比較,有顯著性差異(χ2=4.821,P=0.028)。2.MVD計(jì)數(shù),在侵襲性垂體腺瘤中為42.27±8.04,在非侵襲性垂體腺瘤中為30.31±6.16,經(jīng)統(tǒng)計(jì)學(xué)分析有明顯差異(t=5.539,p=0.000)。3.經(jīng)統(tǒng)計(jì)學(xué)分析,侵襲性垂體腺瘤中Fascin的表達(dá)水平均與MVD計(jì)數(shù)呈正相關(guān)(r=0.713,p=0.000)。結(jié)論1.與非侵襲性垂體腺瘤組相比,F(xiàn)asc
3、in在侵襲性垂體腺瘤中均有高表達(dá),提示侵襲性垂體腺瘤的生物學(xué)行為與Fascin的高表達(dá)有關(guān)。2.侵襲性垂體腺瘤組中MVD計(jì)數(shù)明顯高于非侵襲性垂體腺瘤組,提示垂體腺瘤的侵襲性與血管生成密切相關(guān)。3.侵襲性垂體腺瘤組工Fascin的表達(dá)均與垂體腺瘤中MVD計(jì)數(shù)成正相關(guān),提示Fascin可能通過促進(jìn)腫瘤的微血管生長來促進(jìn)腫瘤的生長、侵襲甚至轉(zhuǎn)移。關(guān)鍵詞:垂體腺瘤,F(xiàn)ascin,MVD,侵襲性I山西醫(yī)科大學(xué)碩士學(xué)位論文ExpressionoffascinandcorrelateswiththeinvasionofpituitaryadenomaAbstract
