对63例临床疑诊HGH分泌缺乏的儿童进行精氨酸激发试验，A组30例，行胰岛素激发试验石组33例行运动激发试验。以激发后测得HGN最高值为峰值，峰值≥10ng／ml为激发试验阳性，＜10ng／ml为阴性。结果三种激发试验HGH峰值出现时间不同。激发试验阳性率精氨酸为20．6％，胰岛素70．0％，运动试验12．1％，胰岛素激发试验阳性率与精氨酸和运动试验比较有显著性差异（P＜0．001），精氨酸与运动试验阳性率比较无显著性差异（P＞0．05）。提示胰岛素激发试验阳性率最高，最为敏感。
Sixty-three children with clinically suspected HGH secretion were challenged with arginine challenge test. A group of 30 patients underwent insulin challenge test stone group 33 exercise stimulation test. In order to stimulate the measured peak value of HGN peak, peak ≥ 10ng / ml positive test for challenge, <10ng / ml was negative. Results Three kinds of excitation test showed different appearance time of HGH peak. The positive rate of provocation test was 20.6% for arginine, 70.0% for insulin and 12.1% for exercise test. The positive rate of insulin provocation test was significantly different from that of arginine and exercise test (P <0.001) There was no significant difference between arginine and exercise test (P> 0.05). Prompt insulin test the highest positive rate, the most sensitive.
