赖氨酰氧化酶(LOX)在盆腔器官脱垂中的异常表达及临床意义

目的:通过对阴道前壁组织中赖氨酰氧化酶(LOX)蛋白表达水平的检测及其相关性的研究,分析赖氨酰氧化酶(LOX)与盆底器官脱垂(POP)发生的关系及与年龄、产次、体重指数、绝经时间的相关性分析。方法:取绝经前后POP组和对照组共4组46例患者,应用Western blotting方法检测LOX蛋白表达水平,并应用相关理论作统计学分析。结果:绝经前POP患者阴道前壁组织中赖氨酰氧化酶(LOX)蛋白表达水平明显低于绝经前对照组(p<0. 01),减少44%;绝经后POP患者阴道前壁组织中LOX蛋白的含量明显减少,平均减少幅度为82%;而且其LOX蛋白的表达在POP组与年龄、体重指数、绝经时间、POP的程度呈负相关,而与产次无相关性;在对照组则与产次呈负相关,而与年龄、体重指数无相关性。结论:①POP患者阴道前壁组织中胶原含量减少可能是由于局部LOX蛋白表达减弱所致,提示LOX蛋白表达减弱可能通过影响结缔组织的胶原含量和结构,进而参与POP发生;②POP的发生与年龄、体重指数和绝经状态密切相关。

Expression and clinical significance of lysyl oxidase on pelvic organ prolapse

Objective:To determine the expression of lysyl oxidase(LOX) in subjects with pelvic organ prolapse as compared to asymptomatic controls,to explore whether the alteration in LOX expression could contributed to pelvic organ prolapse (POP) and analysis the relationship between LOX and etiology of POP.Method:Transvaginal biopsies were obtained from the anterior vaginal in POP and in comparable control.Forty- six women participated in the study and they were divided into 3 groups. Western blotting study was perf...
