Figure 1. Individual heights at the start of the study (○) and after 7 yr of GH treatment (•) in groups A, B, and C, respectively. Twelve girls had completed the trial during the 7-yr study period (▪). Reference curves for healthy Dutch girls (3rd, 10th, 50th, 90th, and 97th percentiles) and for untreated girls with TS (North European references; 3rd, 50th, and 97th percentiles) are given.

生长落后的机制
Turner综合征患儿生长落后的具体机制不清 • 生长激素(GH)分泌异常。
关于Turner综合征患儿的GH分泌情况存在着争议
• SHOX基因缺陷:与性腺发育不良和矮身材有关。
Turner综合征患者GH分泌状况
• GH治疗可持续到生长速率<2cm/y,或BA超过15y 。 • 早期足量应用 GH可以使 TS 患儿达到正常身高范围
• 一项对68例2-11岁患儿的研究表明,GH治疗剂量为0.27IU/Kg.d 时,促生长作用明显优于小剂量的 0.1IU/Kg.d
