生长激素 (GH)/胰岛素样生长因子-1 轴不仅对于儿童时期的线性身体生长很重要,而且也是成人骨量的主要决定因素之一。研究表明,GH 治疗可以增加啮齿类动物以及缺乏 GH 的成人的骨量,但 GH 治疗对健康人骨量的影响迄今为止并不显着。最近,开发出了一类新的 GH 促分泌素 (GHS)。在人类中,GHS 治疗会影响骨转换的生化标志物,并提高患有或不患有 GH 缺乏症的矮个子儿童的生长速度。在啮齿动物中,GHS 治疗会增加骨矿物质含量,但尚未表明 GHS 治疗会影响成年人的骨量。
The growth hormone (GH)/insulin-like growth factor-1 axis is not only of importance for linear body growth during childhood, but it is also one of the major determinants of adult bone mass. Studies show that GH treatment increases bone mass in rodents as well as in adult GH-deficient humans, but the effect of GH treatment on bone mass in healthy humans has so far not been impressive. Recently, a new class of GH secretagogues (GHSs) has been developed. In humans, GHS treatment affects biochemical markers of bone turnover and increases growth velocity in selected short children with or without GH deficiency. In rodents, GHS treatment increase bone mineral content, but it has not yet been shown that GHS treatment can affect bone mass in adult humans.
