摘要 目的 探讨姜黄素对钛颗粒诱导的小鼠气囊植骨模型溶骨的保护作用。方法 取30只雌性适龄BALB/c小鼠制备气囊植骨模型,将其随机分为空白组、模型组、姜黄素组,每组10只。造模结束后,观察骨片与气囊组织形态,TRAP染色检测破骨细胞数目,RT-qPCR法检测小鼠破骨细胞中TRAP、NFATc1、OPG、RANKL mRNA表达,ELISA法检测小鼠植入颅骨中TNF-α、IL-1β、IL-6、OPG、RANKL水平,检测各组小鼠血清中ALT、AST、Cre、BUN活性。结果 与模型组比较,姜黄素组小鼠植入骨片破坏缓解,破骨细胞数量减少(P<0.05),破骨细胞活跃减弱,颅骨组织中TRAP、NFATc1、RANKL mRNA表达降低(P<0.05),OPG mRNA表达升高(P<0.05);空白组与姜黄素组小鼠血清中ALT、AST、Cre、BUN活性比较,差异无统计学意义(P>0.05)。结论 姜黄素可通过抑制RANKL信号通路来减轻钛颗粒诱导的小鼠气囊植骨模型的炎症骨溶解。
