绝经后女性血清脂肪因子瘦素、抵抗素、内脂素及Apelin与骨转换生化指标的关系

目的探讨绝经后女性血清脂肪因子瘦素(Leptin)、抵抗素(Resistin)、内脂素(Visfatin)及Apelin与骨转换生化指标的关系。方法酶联免疫吸附试验测定287名40～80岁健康绝经后女性血清Leptin、Resistin、Visfatin和Ape-lin,以及血清骨特异性碱性磷酸酶(Bonealk aline phosphatase,BAP)和Ⅰ型胶原交联氨基末端肽(cross-linked N-telopep-tide of type I collagen,NTx);用双能X线骨密度扫描仪(dual energy X-ray absorptiometry,DEXA)测定总体、腰椎正位、左前臂、总髋部骨密度(bone mineral density,BMD)以及体脂、瘦体质量;以方差分析、直线相关(Pearson)分析它们之间的关系。结果BAP与总体BMD、腰椎BMD、髋部总体BMD、前臂BMD均呈负相关(r=-0.210、-0.236、-0.223、-0.226,P0.05),校正年龄和BMI后,相关性都依然存在(r=-0.168、-0.187、-0.169、-0.175,P0.05)。NTx与总体BMD、腰椎BMD、髋部总体BMD、前臂BMD均呈负相关(r=-0.238、-0.232、-0.239、-0.221,P0.05),校正年龄和BMI后,相关性依然存在(r=-0.201、-0.189、-0.193、-0.185,P0.05)。Leptin、Resistin、Visfatin、Aplein与BAP、NTx相关差异均无统计学意义。绝经后骨质疏松女性与健康对照组间血清Leptin、Resistin、Visfatin、Apelin水平差异无统计学意义(P0.05)。结论Leptin、Resistin、Visfatin及Apelin不是骨代谢的关键调控因子。

Relationship Between Serum Leptin,Resistin,Visfatin,Apelin and Bone Turnover Biological Marker in Postmenopausal Women

Objective To investigate the correlation between serum leptin,resistin,visfatin,apelin and bone turnover biological marker in postmenopausal women. Methods The serum leptin,resistin,visfatin,apelin and bone alkaline phosphatase (BAP),cross-linked N-telopeptide of type I collagen (NTx) of 287 healthy women aged from 40 to 80 years were measured by ELISA. Bone mineral density (BMD) of total body,lumbar spine,total hip,total forearm,fat mass and lean tissue weight were evaluated by dual energy X-ray absorptiom...
