摘　　要：目的探讨重组人生长激素（r-h GH）对特发性矮小（ISS）儿童的糖、脂代谢及甲状腺功能的影响。方法选取2009年1月至2013年1月应用r-h GH治疗并定期随访的ISS儿童47例,年龄为10±3岁,治疗期限为3~24个月,随访间隔为每3个月1次,检测治疗后0~1年及治疗后1~2年时的空腹血糖、胰岛素、血脂、甲状腺功能等指标的变化。结果 r-h GH治疗后,患儿空腹血糖、胰岛素水平、胰岛素敏感指数、空腹血糖/胰岛素比值（FGIR）与治疗前比较差异无统计学意义,但FGIR有下降趋势;FGIR〈7（提示胰岛素抵抗）的患儿治疗前为13%（6/47）,治疗后1~2年为18%（4/22）。治疗后动脉粥样硬化指数较前下降,而总胆固醇、甘油三酯、高密度脂蛋白、低密度脂蛋白水平及BMI与治疗前比较差异无统计学意义。治疗前后甲状腺功能无明显变化。结论 r-h GH治疗ISS儿童是安全可靠的,可改善脂代谢,对甲状腺功能、空腹血糖、胰岛素水平无明显影响,但有胰岛素敏感性降低的可能。Objective To study the effects of recombinant human growth hormone （r-hGH） replacement therapy on glucose and lipid metabolism and thyroid function in children with idiopathic short stature （ISS）. Methods Forty- seven ISS children with a mean age of 10±3 years treated between January 2009 and January 2013 were enrolled. All children underwent r-hGH replacement therapy for 3-24 months and were followed up once every 3 months. Fasting blood glucose （FBG）, insulin （INS）, blood lipids and thyroid function were measured before treatment and after 0-1 and 1-2 years of treatment. Results After treatment with r-hGH, there were no significant changes in FBG, INS, insulin sensitivity index （ISI）, and FBG/INS ratio （FGIR）, but the FGIR showed a declining trend. The percentage of patients with FGIR〈7 （a marker of insulin resistance） was 13% before treatment compared to 18% 1-2 years after treatment. The atherosclerosis index decreased after r-hGH treatment, but there were no significant changes in total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and BMI. Furthermore, no significant change in thyroid function was observed after r-hGH therapy. Conclusions r-hGH therapy can improve lipid metabolism, without significant impacts on thyroid function, FBG and INS. It seems to be a safe and reliable therapy for children with ISS. However, this therapy possibly reduces insulin sensitivity.
