摘要 目的观察采用小间隙桥接法修复大鼠坐骨神经损伤时套管内Gap-43 mRNA含量的变化。方法SD大鼠78只,随机分为13组,每组6只。其中6组切断右侧坐骨神经并原位缝合,另6组切断右侧坐骨神经采用小间隙桥接法修复,1组为正常对照。分别于术后1d、3d、5d、7d、14d、28d以吻合口为中心,取上下各5mm共1cm坐骨神经提取总RNA,采取实时荧光定量反转录聚合酶链(Real-time RT—PCR)技术检测组织中Gap-43 mRNA含量变化。结果鼠周围神经中Gap-43 mRNA含量在正常组织有低水平表达,在损伤后1d即升高,在损伤后28d降低,但仍高于正常坐骨神经内表达水平。桥接缝合组Gap-43表达高于外膜缝合组。结论大鼠坐骨神经损伤后采用不同修复方法其Gap-43基因表趋势相似,但由套管形成的封闭空间蕴含了较高的神经再生相关因子,有利于神经再生。
