关注生长激素轴和性激素及其受体后信号对青春期生长调控和相关治疗的意义

Notion to the significance of somatotropic axis, gonadal hormones with their post receptor signaling for growth modulating, and relevant treatment during adolescence with growth disorders

青春发育年龄呈年代提前的趋势已是众所周知.性征发育和线性生长突增是青春期并列的两大事件.青春期生长呈加速-减速-停止生长的模式为人类所特有,并受性腺轴和生长激素轴的协同调控.本文阐述近年来青春期生长调控机制的进展,尤其是生长板局部的调控,有助于解读青春期的生长模式、指导对青春期生长的合理评估.同时也将从促进骨骼的线性生长/成熟正平衡的概念出发,讨论围绕改善影响成年身高的青春期生长障碍的治疗现状.

It is well known that a decline secular trend evaluated in the age of puberty onset.Sexual characteristics and linear growth spurt are two major events for puberty.The growth pattern of puberty characterized as acceleration-deceleration-cessation in growth velocity is specific for human being.It is modulated symphonically by both gonadal and somatotropic axes.This article reviews the advances in the modulming mechanisms of pubertal growth,particularly in the local sites of growth plate,and the concept of keeping positive balance between skeletal lineal growth and maturation.Finally,various therapeutic strategies for improving the final adult height in individuals with growth disorders during adolescence are discussed.
