摘要

目的

观察重组人生长激素（rhGH）对儿童特发性矮小症（ISS）的治疗效果，建立rhGH治疗后生长速率的预测模型并加以验证。

方法

选取2020年6月至2021年12月在乌鲁木齐市第一人民医院采用rhGH治疗的152例ISS患儿为研究对象，比较治疗前后各时期生长指标变化。以治疗12月后年生长速率（GV）为因变量，采用多元逐步回归方法确定rhGH疗效的相关预测因素并构建预测模型，并对模型准确度予以验证。

结果

rhGH治疗6个月、12个月的身高（Ht）、身高标准差比值（HtSDS）均逐渐升高（

0.05），rhGH治疗12个月的身高增长（△Ht）、GV均低于治疗6个月（

0.05）；同时治疗6个月与12个月GV均与生活年龄（CA）、Ht、骨龄指数（BAI）、GH峰、垂体高度呈负相关（

0.05），与遗传靶身高（TH）、骨龄差（BAD）呈正相关（

0.05），而治疗6个月GV还与HtSDS呈正相关（

0.05）；将治疗12个月GV作为因变量，治疗前Ht（

）、BAD（

）、GH峰（

）及治疗6个月GV

（

）被纳入方程，建立预测模型：

=4.338-0.062

+0.012

-0.030

+0.772

，

=0.731，并通过外部验证。

结论

rhGH对ISS患儿的生长发育具有较好疗效，且治疗中身高的增长是非匀速连续生长。治疗后患儿GV与多因素相关。以治疗前Ht、BAD、GH峰，及治疗6个月GV为预测因素构建的多元回归模型具有较好的预测效能。

Abstract

Objective

To observe the curative effect of recombinant human growth hormone (rhGH) on idiopathic short stature (ISS) children

and to establish a predictive model of growth rate after rhGH treatment and verify it.

Methods

A total of 152 ISS children treated with rhGH in Urumqi First People's Hospital from June 2020 to December 2021 were selected as the study objects. The growth indexes were compared before and after treatment. And with growth velocity (GV) at 12 months as the dependent variable

the multiple stepwise regression method was used to determine the relevant predictors of rhGH efficacy and construct a prediction model

and the accuracy of the model was verified.

Results

Height （Ht） and height standard deviation scores （HtSDS） gradually increased at 6 and 12 months of rhGH treatment (

0.05)

and △Ht and GV at 12 months of rhGH treatment were lower than those at 6 months of treatment (

0.05). At the same time

GV at 6 and 12 months of treatment was negatively correlated with chronological age （CA）

bone age index （BAI）

GH peak

and pituitary height (

0.05) and positively correlated with target height （TH） and bone age difference （BAD） (

0.05)

while GV at 6 months of treatment was also positively correlated with HtSDS (

0.05). In addition

GV at 12 months of treatment was used as the dependent variable

and Ht (

)

BAD (

)

GH peak (

)

and GV

(

) at 6 months of treatment were included in the equation to establish a prediction model:

=4.338-0.062

+0.012

-0.030

+0.772

=0.731

and the model was verified externally.

Conclusion

The rhGH treatment has a good curative effect on the height growth of ISS children

and the increase in height during treatment is non‑uniform

with continuous growth. After treatment

GV was associated with multiple factors. The multiple regression model constructed with Ht

BAD

GH peak before treatment

and GV at 6 months after treatment as predictors had good predictive power.
