1、福建医科大学硕士学位论文退变腰椎间盘髓核组织中ADAMTS-5蛋白表达的临床意义姓名:卢永江申请学位级别:硕士专业:外科学(骨外科)指导教师:徐杰20100301中文摘要退变腰椎间盘髓核组织中ADAMTS.5蛋白表达的临床意义目的:研究ADAMTS.5在退变的腰椎间盘髓核组织中的表达,探讨其对腰椎间盘退变的影响。方法:①实验组:退变的腰椎间盘髓核组织,取1112009年3月至2009年9月期间在福建省立医院骨二科住院手术的腰椎间盘突出症患者行手术摘除的髓核标本,共30例(男15例,女15例),平均年龄40.58(24"-63)岁。②对照组:外伤性腰
2、椎骨折患者的腰椎间盘髓核组织,取自同期在福建省立医院骨二科住院手术的腰椎骨折,共28例(男18例,女10例),年龄13"--22岁,平均(15.254-1.54)岁。所有标本分别制作为石蜡和冰冻切片,用HE染色法对两组髓核标本进行组织形态学比较,免疫组织化学研究ADAMTS.5在实验组和对照组中的表达情况。结果:1、HE染色组织学观察在退变间盘中,各标本均表现出一定的退变特征,髓核细胞空泡化,出现肥大软骨细胞巨克隆,呈现出软骨细胞的“巢状”结构,软骨样软骨细胞外周胶原纤维排列混乱。2、免疫组织化学S-P法检测椎间盘细胞ADAMTS一5的蛋白表达,在
