【摘要】 目的:比较重组人生长激素(rhGH)对儿童生长激素缺乏症(GHD)、特发性矮小症(ISS)、小于胎龄儿(SGA)和骨及软骨相关矮小症(BCD)治疗效果。方法:观察胰岛素样生长因子-1(IGF-1)、胰岛素样生长因子结合蛋白-3(IGFBP-3)、骨龄(BA)、生长速率(GV)、骨代谢指标(胶原羧基末端肽同分异构体(CTX)、骨钙素(OC)、碱性磷酸酶(AKP)等在治疗前后变化的情况。通过对比治疗前后基线水平的改变来判断药物的疗效,治疗后各组的对比来判断药物对不同矮小症患儿的疗效及可能发生的机制。结果:治疗6个月后,四组IGF1、IGFBP-3、AKP、OC、CTX较治疗前均显著升高(P<0.05)。GHD组身高、生长速率升高最明显,而BCD组升高最少(P<0.01)。GHD组IGF1和IGFBP-3及骨形成指标OC和AKP均改变最显著,而BCD组水平低于其他组(P<0.01)。结论:rhGH治疗矮小症能通过促进IGF1、IGFBP-3的调节来提高生长速率,加快骨吸收和骨形成,促进骨量的积累和软骨及骨细胞的生长,且不会导致骨骺线提前闭合。rhGH治疗GHD疗效最佳,其他患儿疗效均优于BCD患儿。

【Abstract】 Objective:To compare the effects of Recombinant Human Growth Hormone(rhGH)in the treatment of growth hormone deficiency(GHD),idiopathic short stature(ISS),small for gestational age(SGA),and short stature related with bone and cartilage diseases(BCD).Method:The change of insulin-like growth factor-1(IGF-1),insulin-like growth factor binding protein-3(IGFBP-3),bone age(BA),growth velocity(GV),and bone metabolism index including isomer of carboxyl terminal peptide of collagen(CTX),osteocalcin(OC),alkaline phosphatase(AKP)of before and after rhGH treatment of four groups were observed.Result:After 6 months of treatment,the levels of IGF1,IGFBP-3,AKP,OC and CTX in four groups were significantly higher than those of before treatment(P<0.05).Compared with four groups,the height and growth rate of GHD group increased most obviously,while those of BCD group increased the least(P<0.01).The changes of IGF1 and IGFBP-3 and bone formation index OC and AKP in GHD group were most significant and in those of BCD group were lower than those of the other groups(P<0.01).Conclusion:rhGH in the treatment of short stature can promote the growth rate,accelerate bone resorption and bone formation,promote bone mass accumulation and cartilage and bone cell growth by promoting the regulation of IGF1 and IGFBP-3,without causing the epiphyseal line to close early.The effect of rhGH in GHD is the best,and BCD is less effective than those of the other children.

隨着人们生活水平的提高,社会竞争压力的加大,身高成为在儿童成长过程中家长越来越关注的问题之一。儿童矮小症是指小儿身高处于同种族、同年龄、同性别正常健康儿童生长曲线第3百分位数以下,或低于两个标准差。人们不断探索矮小症的发病机制,研究新的治疗方法(如IGF-1治疗、基因治疗等)。但是目前皮下注射外源性的重组人生长激素仍然是治疗儿童矮小症公认的治疗方法。本研究选择2014年8月-2017年10月在本院就诊的矮小儿童184例进行研究。现报道如下
1 资料与方法
1.1 一般资料 选择2014年8月-2017年10月在本院就诊的矮小儿童184例,其中男104例,女80例,年龄3.5~9.7岁,平均(6.3±2.7)岁。纳入标准:足月小于胎龄患儿、青春期前(TannerⅠ期)、身高低于同龄同性别儿童平均身高2个标准差、骨龄≤实际年龄+1、出生胎龄≥37周、空腹血糖浓度小于5.6 mmol/L;排除标准:非足月矮小患儿、之前接受过其他针对矮小症治疗者、有明显的遗传或代谢性疾病导致的矮小症。……
