入选标准
- •Diagnosed as GHD before starting treatment, according to medical history, clinical symptoms and signs, GH provocation tests and imaging and other examinations:
- •According to statistical height data of physical development of Chinese children in nine cities in 2005, the height is lower than 3rd percentile growth curve of the same age, same sex normal children;
- •Height velocity (HV) ≤5.0 cm / yr;
- •GH provocative tests (with two drugs of different mechanism of action) confirmed plasma GH peak <10.0 ng / ml;
- •bone age for girl≤9 years old, for Boy≤10 years old, bone age is one year or more later than the actual age, that is the actual age - bone age ≥ 1 year;
- •Before puberty (Tanner I stage), age≥3 years old, male or female;
- •Have not received hormone therapy within 6 months;

研究组 & 干预措施
PEG-somatropin
30IU/10 mg/3ml/kit, 0.1-0.2mg /kg/w, once per day for 26 weeks.
干预措施: PEG-somatropin (Biological)
结局指标
主要结局
Ht SDSca (Height Standard Deviation Score for Chronological Age)
时间窗: Baseline
Ht SDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age
Change of yearly growth velocity from baseline to 26 weeks
时间窗: Baseline, 26 weeks after initiating treatment
Height velocity calculate by formula
Ht SDSca
时间窗: 26 weeks after initiating treatment
Ht SDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age
次要结局
- Skeletal maturity(Baseline,26 weeks after initiating treatment)
- IGF-1 SDS (IGF-1 Standard Deviation Score)(Baseline,26 weeks after initiating treatment)
- Ht SDSBA (Height Standard Deviation Score for Bone Age)(Baseline,26 weeks after initiating treatment)
- IGFBP-3 SDS (IGFBP-3 Standard Deviation Score)(Baseline,26 weeks after initiating treatment)
