摘要(Abstract)：

[目的]检测Sox9及软骨特异性标记物Ⅱ型胶原及Aggrecan在青少年特发性脊柱侧凸(adolescent idiopathic scoliosis, AIS)患者关节突软骨细胞中的表达,探讨其与AIS发生、发展的关系。[方法]收集我院行后路脊柱侧凸矫形术的15例AIS患者的关节突软骨标本,设为AIS组;取同年龄段无脊柱侧凸行脊柱融合术的10例患者正常软骨标本,设为对照组。分别分离软骨细胞体外培养,分别采用RT-PCR,免疫组化,免疫荧光染色和Westen-blotting等方法检测AIS组及对照组软骨Sox9及Ⅱ型胶原及Aggrecan的表达情况,进行两组间比较和AIS组凸侧与凹侧间比较。[结果] AIS组患者软骨细胞内的Sox9及软骨特异性标记物CollagenⅡ及Aggrecan的表达明显高于非AIS组患者。相比于凹侧,AIS患者顶椎凸侧原代软骨细胞中Sox9及软骨特异性标记物CollagenⅡ及Aggrecan表达明显升高。[结论] Sox9在AIS患者体内及原代软骨细胞中的表达异常是AIS患者体内软骨发育异常及脊柱不平衡生长的重要原因,可能是AIS发生、发展的原因之一。
