目的研究不同類型(囊狀、梭狀型)先天性膽總管囊腫壁細(xì)胞凋亡與增殖的關(guān)系,了解細(xì)胞凋亡/增殖在膽總管囊腫中的作用。方法以膽總管囊狀擴(kuò)張組32例、梭狀擴(kuò)張組35例及膽總管結(jié)石致膽管擴(kuò)張組(對(duì)照組)25例為研究對(duì)象。術(shù)中取部分膽總管壁送檢,觀察膽總管壁損傷情況。用免疫組織化學(xué)法檢測(cè)細(xì)胞凋亡的相關(guān)指標(biāo)bcl2、bax及細(xì)胞增殖指標(biāo)PCNA的表達(dá); 用TUNEL法檢測(cè)細(xì)胞凋亡情況。結(jié)果囊狀擴(kuò)張組膽總管壁粘膜上皮細(xì)胞破壞嚴(yán)重,梭狀擴(kuò)張組鏡下所見(jiàn)與囊狀擴(kuò)張組相似,但程度較輕。對(duì)照組膽總管粘膜上皮細(xì)胞破壞最輕,其凋亡細(xì)胞呈散在分布,上皮細(xì)胞和成纖維細(xì)胞凋亡陽(yáng)性率較低,分別為(2.74±1.00)%和(2.95±0.87)%; bcl2、bax表達(dá)率較低,水平相似(P gt;0.05); PCNA表達(dá)率較高,分別為(3.74±1.00)%和(3.71±1.77)%。囊狀擴(kuò)張組與梭狀擴(kuò)張組囊壁殘留上皮中的bcl2和PCNA表達(dá)率低,分別為(0.99±0.51)%和(0.90±0.38)%; bax呈高表達(dá),bcl2呈低表達(dá),凋亡細(xì)胞陽(yáng)性率較高,分別為(13.94±4.77)%和(7.51±3.46)%; 成纖維細(xì)胞中的PCNA表達(dá)率較高,分別為(9.91±2.91)%和(9.70±3.18)%,bax呈低表達(dá),bcl2呈高表達(dá),凋亡細(xì)胞陽(yáng)性率較低,分別為(3.74±2.12)%和(4.46±2.41)%。兩組之間上述各項(xiàng)指標(biāo)比較無(wú)明顯差異(P gt;0.05),但兩組的bcl2和bax的表達(dá)與對(duì)照組比較則明顯升高(P<0.05)。結(jié)論細(xì)胞凋亡在膽總管囊腫形成中有一定的促進(jìn)作用。
