摘要 目的探讨雷尼酸锶对骨质疏松股骨折愈合的影响。方法选用成年雌性SD大鼠40只,采用双侧卵巢切除和骨折手术方法建立骨质疏松股骨折(OPF)模型。将大鼠分为对照组和实验组,实验组给予雷尼酸锶(Strontium ranelate,SR),对照组给予同体积生理盐水。X线观察骨折断端愈合情况,检测二组大鼠股骨骨密度(BMD),HE染色观察骨痂组织,免疫组织化学方法检测骨形态发生蛋白-2(BMP-2),抗酒石酸酸性磷酸酶染色检测破骨细胞数。结果①OPF术后6周实验组骨折断端骨痂较大,有连续骨痂通过骨折断端;对照组骨折断端骨痂较小;②OPF术后2周,实验组BMP-2表达阳性细胞数高于对照组(P<0.05)。术后6周,实验组较对照组骨折愈合明显,BMP-2表达高于对照组(P<0.05);③OPF术后6周时,实验组骨小梁面积比和骨小梁平均宽度高于对照组,骨小梁平均间隔小于对照组(P<0.05)。④实验组破骨细胞数量减少(P<0.05)。⑤OPF术后2、6周,实验组BMD高于对照组(P<0.05)。结论研究结果提示雷尼酸锶可促进骨质疏松股骨折愈合,增加骨密度,抑制破骨细胞。
