补肾活血方联合骨髓间充质干细胞-藻酸钙复合体修复关节软骨缺损研究
China Journal of Traditional Chinese Medicine and Pharmacy(2017)
Abstract
目的:观察补肾活血方联合骨髓间充质干细胞(BMSCs)-藻酸钙复合体体治疗大鼠膝关节软骨缺损的疗效,探讨其作用机制.方法:48只大鼠全层软骨缺损造模随机分成4组:模型组、补肾活血组、BMSCs-藻酸钙组、补肾活血联合BMSCs-藻酸钙组.补血活血组术后8周每天给予补肾活血方灌胃;其余组术后每天给予等量0.9%氯化钠溶液灌胃.在第4、8周分批处死,收集并作相关检测.结果:形态学、病理组织学染色及Mankin评分结果表明,模型组软骨缺损损伤加重,伴有纤维组织增生.其余组缺损可见组织填充修复,尤以补肾活血联合BMSCs-藻酸钙组修复组织最佳.Real-time PCR结果证实,补肾活血联合BMSCs-藻酸钙组修复组织中Ⅱ型胶原、聚集蛋白聚糖的mRNA表达明显高于其余各组(P<0.01).结论:补肾活血方和BMSCs-藻酸钙复合体单独使用对关节软骨缺损均具有一定的修复治疗作用,两者联合使用时通过增加Ⅱ型胶原和聚集蛋白聚糖合成,软骨修复效果达到最好.
