【摘要】:目的:研究盆腔器官脫垂(pelvic organ prolapse,POP)患者陰道壁、骶主韌帶的組織結(jié)構(gòu)特點(diǎn)、神經(jīng)纖維損傷及血管活性腸肽(VIP)、神經(jīng)肽Y(NPY)表達(dá)的特點(diǎn),分析與POP疾病發(fā)生的相關(guān)性。 方法:選擇廣西醫(yī)科大學(xué)第一附屬醫(yī)院婦產(chǎn)科2013年1月~2014年3月收治的35例患者,分為三組:POP(Ⅰ-Ⅱ)組7例、POP(Ⅲ-Ⅳ)組8例和對(duì)照組(非POP患者)20例。標(biāo)本選取陰道前壁、子宮骶韌帶及主韌帶組織,采用HE染色和免疫組化染色,光鏡下觀察各組切片組織結(jié)構(gòu)及神經(jīng)纖維束特點(diǎn),計(jì)算神經(jīng)纖維束密度,采用Leica Owin系統(tǒng)測(cè)定血管周圍VIP、NPY灰度值,采用t檢驗(yàn)、方差分析(AVOVA)檢驗(yàn)方法對(duì)數(shù)據(jù)進(jìn)行分析。 結(jié)果:⑴陰道分娩次數(shù)對(duì)照組與POP(Ⅰ-Ⅱ)組、POP(Ⅲ-Ⅳ)組分別比較,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05),POP(Ⅰ-Ⅱ)組與POP(Ⅲ-Ⅳ)組比較,差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05);⑵HE染色結(jié)果顯示POP患者陰道壁、骶主韌帶組織結(jié)構(gòu)薄弱,其嚴(yán)重程度與POP病情呈正相關(guān);骶韌帶和主韌帶組織結(jié)構(gòu)具有相似性;⑶POP患者陰道壁、骶韌帶及主韌帶神經(jīng)纖維損傷主要表現(xiàn)為神經(jīng)纖維束結(jié)構(gòu)改變,與POP病情呈正相關(guān),而神經(jīng)纖維束密度三組之間比較,差異均無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05),同一患者骶、主韌帶神經(jīng)纖維束密度比較,差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05);⑷陰道壁、骶韌帶及主韌帶組織中血管周圍VIP、NPY灰度均值三組間比較,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05),對(duì)照組<POP(Ⅰ-Ⅱ)組<POP(Ⅲ-Ⅳ)組,灰度均值越高表示VIP、NPY表達(dá)量越低。 結(jié)論:⑴陰道分娩次數(shù)是陰道壁、骶主韌帶神經(jīng)損傷及POP發(fā)生的主要高危因素。⑵骶韌帶和主韌帶組織結(jié)構(gòu)相似,神經(jīng)纖維束密度相當(dāng),提示骶、主韌帶具有同源性。⑶POP患者陰道壁、骶主韌帶組織中神經(jīng)纖維損傷主要表現(xiàn)為神經(jīng)纖維束結(jié)構(gòu)的改變,而非神經(jīng)纖維束密度,且VIP、NP表達(dá)量減少,導(dǎo)致盆底組織結(jié)構(gòu)改變而發(fā)生POP,提示VIP、NPY表達(dá)在POP的發(fā)生、發(fā)展中起重要作用。
