Inclusion Criteria
  • Before starting treatment, the child is diagnosed as GHD according to medical history,clinical symptoms and signs, GH provocation tests and imaging examinators and other examinators.
  • According to the height statistical data of Chinese children's physical development in nine cities in 2015, the height of the child is lower than the third percentile of normal children's growth curve in the same age and same gender.
  • Height velocity (HV) ≤5.0 cm/yr.
  • GH provocation tests with two different mechanisms showed that GH peak concentration of the child is < 10.0ng/ml.
  • Bone age (BA) ≤9 years in girls or ≤ 10 years in boys, and the BA is 1 year less than the CA.
  • Prepuberty status (Tanner I stage), age ≥3 years old, girls and boys are acceptable.
  • The child did not receive the treatment of growth hormone within 6 months.
  • Subjects are willing and able to cooperate to complete scheduled visits, treatment plans and laboratory tests and other procedures, and they sign informed consent.
Exclusion Criteria
  • The child is dysfunction of liver and kidney (ALT) 2 times of the upper limit of normal value, Cr> the upper limit of normal value).

Primary Outcome Measures
NameTimeMethod
The change of Height Standard Deviation Score for Chronological Age before and after the treatment (ΔHtSDSCA)26 weeks

HtSDSCA = (Height at the evaluated time point- the mean value of normal children in the same gender and same age) / the height SD of normal children in the same gender and same age

Secondary Outcome Measures
NameTimeMethod
HtSDSBA26 weeks

HtSDSBA = (height at the evaluated time point-the mean value of normal children in the same gender and same age) / height SD of normal children in the same bone age and same gender

Bone Maturation26 weeks

Bone Maturation = (BA at the end of treatment-BA at the beginning of treatment)/ the treatment duration (Year)

Annual height velocity26 weeks

Annual Growth Velocity (cm/yr) = 12×(Height at the end of treatment-Height at the beginning of treatment)/the treatment duration (month)

Standard Deviation Score of serum IGF-1 (IGF-1 SDS)26 weeks

IGF-1 SDS = (actual concentration of IGF-1-the median of IGF-1 concentration of normal children in the age and same gender) / SD of IGF-1 concentration of normal children in the same gender and same age
