摘要:目的 探讨儿童青少年血清胰岛素生长因子-1(IGF-1)及胰岛素因子结合蛋白-3(IGFBP-3)的正常参考值。方法 选取2018年1月~2019年1月在我院体检的312例健康的儿童、青少年为研究对象,分别测定其IGF-1、IGFBP-3水平,并分析IGF-1、IGFBP-3与年龄、性别、发育阶段的关系。结果 男孩血清IGF-1峰值为13岁,女孩为11岁;男孩血清IGFBP-3峰值为14岁,女孩为11岁;高峰值出现后,IGF-1、IGFBP-3水平随年龄增长缓慢下降或维持高峰值;同年龄比较男孩血清IGF-1水平高于女孩、IGFBP-3水平低于女孩,差异有统计学意义(P<0.05);年龄、发育阶段与血清IGF-1值呈正相关(r=0.241,P<0.01),IGFBP-3与年龄呈正相关(r=0.323,P<0.01)。结论 建立儿童青少年IGF-1、IGFBP-3水平正常参考值,可与监测其生长、临床症状以及生长激素治疗后随访具有重要的参考价值。

Abstract:Objective To investigate the normal reference values of serum insulin growth factor-1 (IGF-1) and insulin factor binding protein-3 (IGFBP-3) in children and adolescents. Methods A total of 312 healthy children and adolescents who were examined in our hospital from January 2018 to January 2019 were enrolled in this study. The levels of IGF-1 and IGFBP-3 were measured, and IGF-1, IGFBP-3 and age were analyzed. Relationship between gender, developmental stage. Results The peak of serum IGF-1 in boys was 13 years old and that in girls was 11 years old. The peak of serum IGFBP-3 in boys was 14 years old and that in girls was 11 years old. After high peak appeared, the levels of IGF-1 and IGFBP-3 decreased slowly with age. The peak of serum IGF-1 was higher than that of girls and IGFBP-3 was lower than that of girls,the difference was statistically significant (P<0.05); age and developmental stage were positively correlated with serum IGF-1 (P<0.01), and IGFBP-3 was positively correlated with age (P<0.01). Conclusion The establishment of normal reference values of IGF-1 and IGFBP-3 levels in children and adolescents can be important for monitoring the growth, clinical symptoms and follow-up of growth hormone therapy.

胰島素生长因子-1(insulin growth factor-1,IGF-1)是生长激素刺激靶细胞产生的多肽,血液中90%的IGF-1都是肝脏合成[1]。IGF-1在血液中会与胰岛素因子结合蛋白-3(IGFBP-3)、胰岛素因子结合蛋白结合,然后输送至周围组织中发挥作用。生长激素在机体内通过IGF-1介导发挥促进骨骼生长的租用,并且IGF-1也依赖生长激素。生长激素释放属于脉冲式,故随机抽检无诊断价值。而血液IGF-1、IGFBP-3水平可以反应儿童生长激素的分泌情况,且IGF-1、IGFBP-3在血液中的浓度相对稳定。因此,临床常通过检测IGF-1、IGFBP-3以协助诊断生长激素缺乏症,或对使用生长激素治疗的儿童进行用药检测和疗效评定[2]。本研究选取2018年1月~2019年1月在我院体检的312例健康的儿童、青少年的临床资料,分析IGF-1、IGFBP-3水平的影响因素,为建立血清IGF-1、IGFBP-3的正常参考值提供依据,现报告如下。
