力学刺激对软骨细胞整合素亚单位的调控

骨关节炎（osteoarthritis,OA）是以关节软骨退变、关节缘骨质增生为主要改变的疾病。机械应力可以调节细胞的多种功能,而整合素作为细胞表面应力受体之一,主要介导细胞与细胞外基质（extracellularmatrix,ECM）间的黏附,在传导力学信号从而调节细胞的生理功能方面起着重要作用。因此,在软骨病变早中期选择适当的良性刺激（如推拿手法）作用于软骨,调控整合素的表达影响软骨细胞的功能,修复损伤的软骨细胞,延缓关节软骨退变,这对于骨关节炎的治疗有重要意义。

Effects of mechanical stimulation on expession of integrin subunits in chondrocyte

Osteoarthritis(OA) is a kind of degenerative disease characterized by hyperosteogeny at the joint margins and articular cartilage degeneration. Mechanical stress can regulate the multiple functions of cells. The integrin as one of the mechanoreceptors on the surface of cells,mainly mediated adhesion between cells and extracellular matrix,which plays an important role in the mechanical signal transmission to regulate the physiological functions of cell . Therefore,it is very important to select proper mechanical stimulation(such as naprapathy) in the early and middle stage of osteoarthritis,which regulate the expression of integrins to affect the function of chondrocytes,repair the damaged chondrocyte and delay the articular cartilage degeneration.
