虫草素在骨质疏松症中的骨保护作用

The Bone-Protective Effect of Cordycepin in Osteoporosis

摘要: 骨质疏松是绝经后的妇女和老年人面临的一个主要临床问题，其本质在于骨重塑(bone remodeling)失衡，即成骨细胞(osteoblast)介导的骨形成与破骨细胞(osteoclast)介导的骨吸收之间的动态平衡被打破，导致骨骼脆性增加，发生骨折的概率升高，这会造成身体残疾、医疗费用升高、生活质量受损等后果。目前研究发现炎症、氧化应激、骨稳态失衡等因素会严重影响骨骼的生理功能，从而引发骨质疏松等骨类疾病。因此，找到合适的药物对骨类疾病进行预防和修复尤为重要。虫草素是从蛹虫草内提取出来的活性物质，具有抗炎、抗氧化、改善代谢紊乱等多个功能，并且有多项研究发现虫草素对骨具有明显的修复作用。因此，本篇综述对虫草素在骨质疏松症中的骨保护作用进行梳理，从抗炎、抗氧化、调节骨稳态和骨源细胞因子多个方面进行论述，为治疗骨类药物的研制和开发提供更多的理论依据。

Abstract: Osteoporosis is a major clinical issue faced by postmenopausal women and the elderly. Its essence lies in the imbalance of bone remodeling, where the dynamic equilibrium between osteoblast-mediated bone formation and osteoclast-mediated bone resorption is disrupted. It leads to increased skeletal fragility and a higher likelihood of fractures, resulting in disability, higher medical costs, and a reduced quality of life. Recent studies have found that factors such as inflammation, oxidative stress, and imbalance of bone homeostasis significantly impact bone physiology, contributing to the onset of bone diseases like osteoporosis. Therefore, it is crucial to identify suitable drugs for the prevention and repair of bone diseases. Cordycepin, an active substance extracted from Cordyceps sinensis, has anti-inflammatory, antioxidant, and metabolic regulatory properties. Several studies have shown that cordycepin exerts significant bone-repairing effects. This review examines the bone-protective effects of cordycepin in osteoporosis, focusing on its mechanisms involving anti-inflammation, antioxidant activity, modulation of bone homeostasis, and bone-derived cytokines, providing a theoretical foundation for the development and design of therapeutic agents for bone diseases.
