摘要
目的:探讨血清视黄醇结合蛋白4(RBP4)与2型糖尿病(T2DM)骨转换指标骨钙素(OC)、Ⅰ型胶原C-末端交联顶端肽(CTX)及骨密度(BMD)水平的相关性。方法:128例门诊初诊T2DM患者及同期门诊或体检中心健康体检者,其中正常葡萄糖耐量(NGT)组46例和T2DM组82例,进一步分男女亚组(M-NGT,F-NGT,M-T2DM,F-T2DM)。ELISA测定血清中RBP4,OC,CTX水平;双能X线骨密度仪(DXA)测定各部位BMD。结果:T2DM组无论男性或女性,lnRBP4与lnCTX均存在显著正相关(M-T2DM,r=0.564,P<0.01;F-T2DM,r=0.386,P=0.018),与lnOC不相关;校正年龄、吸烟、血肌酐清除率(CCr)、腰臀比后,M-T2DM的正相关仍显著(r=0.536,P<0.01),而F-T2DM组lnRBP4与lnCTX相关性消失(r=0.317,P=0.072)。NGT组,lnRBP4与lnOC及lnCTX无相关性;无论NGT组还是T2DM组,lnRBP4与各部位BMD均不相关。结论:T2DM患者的血清RBP4可能与骨代谢相关。
Objective:To determine the relation between serum concentration of retinol binding protein (RBP) 4 and markers of bone metabolism, bone mineral density (BMD) in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 82 patients newly diagnosed with T2DM and 46 subjects with normal glucose tolerance (NGT) enrolled in the cross-sectional study. Subset analyses were performed, dividing subjects on the basis of gender into M-T2DM, F-T2DM, M-NGT, and F-NGT. The serum concentrions of RBP4, osteocalcin (OC) and C-terminal telopeptide of collagen type Ⅰ (CTX) were measured with ELISA. The BMD was measured by dual-energy X-ray absorptiometry (DXA) with a Hologic QDR4500A device. Results: In both the T2DM groups, lnRBP4 showed a positive relationship with lnCTX (M-T2DM, r=0.564, P〈0.01; F-T2DM, r=0.386, P=0.018), but no association with lnOC. After adjusting for age, smoking, creatinine clearance rate (CCr), and waist-to-hip ratio (WHR), lnRBP4 still showed a strong association with lnCTX in the M-T2DM group (r =0.536, P〈0.01), but not in F-T2DM (r =0.317, P=0.072). In the NGT group, there was no relation between lnRBP4 and lnCTX or lnOC. LnRBP4 showed no association with BMD in all groups.Conclusion:The level of serum RBP4 may be correlated with the bone metabolism in patients withT2DM.
