摘要(Abstract):
目的观察五福饮对大鼠退变椎间盘聚蛋白聚糖与Ⅱ型胶原表达的影响。方法将48只SD大鼠分成空白对照组、模型组及五福饮组各16只,模型组及五福饮组大鼠应用细针纤维环穿刺结合肿瘤坏死因子-α椎间盘内注射进行造模,造模成功后3组大鼠分别给予生理盐水、生理盐水及五福饮灌胃治疗8周。采用Micro-CT检测脊柱退变情况,HE染色观察椎间盘退变特征,RT-PCR检测椎间盘聚蛋白聚糖与Ⅱ型胶原mRNA的表达。结果造模后,大鼠椎间盘出现明显退变特征,表明造模成功。灌服五福饮8周后,大鼠造模椎间隙相对高度及组织学退变均有改善。五福饮组大鼠与模型组大鼠相比较,椎间盘聚蛋白聚糖与Ⅱ型胶原mRNA表达均有明显提高(P<0.05)。结论五福饮可防治椎间盘退变,提高聚蛋白聚糖与Ⅱ型胶原表达可能是其作用机制。
