晚期糖基化终末产物(AGEs)是由蛋白质经非酶催化的Maillard反应所形成,糖尿病时AGEs的形成和积累加速.AGEs与其受体(RAGE)结合后,引起氧化应激及炎性反应,继而导致成骨细胞、破骨细胞及骨髓间充质干细胞功能改变；同时AGEs与骨基质中胶原蛋白交联还可使骨强度下降,是造成糖尿病性骨质疏松的主要原因.检测血清及尿液中的AGEs成分,可作为评估糖尿病患者骨折发生风险的有效指标.

Advanced glycation end products (AGEs) are chemical modifications of proteins by nonenzymatic Maillard reaction.The formation and accumulation of AGEs have been known to be accelerated when suffered from diabetes.Combinations of AGEs and their receptors (RAGE) cause oxidative stress and inflammation,which result in functional alterations of osteoblasts,osteoclasts and bone mesenchymal stem cells.On the other hand,overcrossslinking of AGEs and collagen can also cause loss of flexibility and elasticity and increase brittleness of bone.Accordingly,AGEs play an crucial role in the development of diabetic osteoporosis.Measurement of serum and urinary AGEs composition can be effective for predicting diabetic osteoporosis.
