近年来,近视发病率逐年增高,尤其在青少年中已成为重大公共卫生问题。重组人生长激素(rhGH)作为青少年矮小症的主要治疗手段,其潜在促进近视进展的风险引起广泛关注。近期研究发现GH可能通过其下游信号通路\〖如胰岛素样生长因子-1(IGF-1)\〗、细胞信号传导(如MMP/TIMP平衡、Wnt/β-catenin通路)及表观遗传机制(如miR-29a和DNA甲基化)等多种途径,起到调控巩膜细胞外基质代谢、眼轴长度等参与近视发展的作用。文章对GH在近视发生发展中的作用研究进展进行综述,以期为矮小症患儿在使用GH治疗期间如何更好地保护视力,避免近视提供参考。

[Abstract]
In recent years, the incidence of myopia has been increasing annually, emerging as a significant public health issue, particularly among adolescents. Recombinant human growth hormone(rhGH), a primary treatment for short stature in children, has raised widespread concern due to its potential to promote myopia progression. Recent studies have revealed that growth hormone(GH)may contribute to the development of myopia by regulating scleral extracellular matrix metabolism and axial length through multiple mechanisms, including downstream signaling pathways\〖e.g., insulin-like growth factor-1(IGF-1)\〗, cellular signaling pathways(e.g., MMP/TIMP balance and the Wnt/β-catenin pathway), and epigenetic mechanisms(e.g., miR-29a and DNA methylation). Therefore, this article reviews recent research progress on the role of GH in the pathogenesis and progression of myopia, with the aim of providing insights into visual protection and myopia prevention strategies for children receiving GH therapy for short stature.
