Abstract:
Objective To explore the role of growth hormone (GH),leptin (Lep),T3,T4,TSH in cord blood in intrauterine growth.Methods 120 healthy newborns (60 males,60 females) were enrolled in this study.The neonates were divided into AGA,LGA and SGA groups according to the relationship between birth weight and gestation.The head circumference,birth length,birth weight,body mass index,biparietal diameter,and placental weight,the levels of GH,Lep,T3,T4,TSH in the cord blood were measured.Results There were significantly statistical differ ences in growth indexs (all P ＜ 0.05),the levels of GH and TSH were significantly increased [(21.52 ± 2.13) ng/L vs (15.64 ± 1.28) ng/L ; (8.6 ± 0.67) mIU/L vs (3.34 ± 0.29) mIU/L,t =3.042,4.367,all P ＜ 0.05] and Lep,T3,T4 were significantly decreased in LGA group when compared with the AGA group [(7.53 ±0.81) g/L vs (9.55 ± 1.26) g/L; (1.25 ± 0.42) nmol/L vs (1.48 ± 0.37) nmol/L; (69.45 ± 10.07) nmol/L vs (76.68 ± 8.22) nmol/L; t =1.749,1.905,1.783,all P ＜ 0.05],the level of Lep in LGA group was significantly higer than that in AGA group [(14.61 ±2.05) g/L vs (9.55 ±1.26) g/L,t =3.064,P ＜0.05].And GH,Lep,T3,T4 were positively correlated with head circumference,birth length,birth weight,body mass index,biparietal diameter,and placental weight (all P ＜ 0.05).TSH was negatively correlated with growth indexs.Conclusion The levels of Lep,T3,T4,TSH in cord blood were associated with fetal growth and could be used as indicators of intrauterine growth.
