骨骼为身高和运动提供机械支持,保护重要器官,并控制矿物质的体内平衡。健康的骨骼必须通过不断的骨骼建模来维持,以在整个生命中执行这些关键功能。骨重建包括通过破骨细胞去除旧骨或受损骨(骨吸收),以及随后通过成骨细胞形成新骨(骨形成)。正常的骨重建需要骨吸收与骨形成的紧密耦合,以保证每个重建周期后骨量或质量没有改变。然而,这一重要的生理过程可能会受到各种因素的影响,包括更年期相关的激素变化,年龄相关因素,身体活动的变化,药物和继发性疾病,导致女性和男性发生各种骨骼疾病。我们回顾了骨重建的主要疾病,强调我们目前对潜在的病理生理机制的理解。
The skeleton provides mechanical support for stature and locomotion, protects vital organs, and controls mineral homeostasis. A healthy skeleton must be maintained by constant bone modeling to carry out these crucial functions throughout life. Bone remodeling involves the removal of old or damaged bone by osteoclasts (bone resorption) and the subsequent replacement of new bone formed by osteoblasts (bone formation). Normal bone remodeling requires a tight coupling of bone resorption to bone formation to guarantee no alteration in bone mass or quality after each remodeling cycle. However, this important physiological process can be derailed by a variety of factors, including menopause-associated hormonal changes, age-related factors, changes in physical activity, drugs, and secondary diseases, which lead to the development of various bone disorders in both women and men. We review the major diseases of bone remodeling, emphasizing our current understanding of the underlying pathophysiological mechanisms.
