目的通过对55例农村乳母乳汁中表皮生长因子、胰岛素样生长因子Ⅰ和转化生长因子β1等生长因子的测定,探讨其在婴幼儿期乳母乳汁中的含量及分布情况。方法随机整群选取陕西省澄城县5个村55名身体健康的农村乳母,测定其乳汁中生长因子表皮生长因子、胰岛素样生长因子Ⅰ和转化生长因子β1的浓度。结果1～17个月乳母乳汁中表皮生长因子、胰岛素样生长因子Ⅰ和转化生长因子β1的浓度变化不大(P>0.05)。结论母乳中表皮生长因子、胰岛素样生长因子Ⅰ和转化生长因子β1可促进婴幼儿生长发育,建议在合理添加辅助食品的情况下适当延长母乳喂养至1岁半。
Objective To investigate the content and distribution of growth factor in epistaxis, insulin-like growth factor-Ⅰ and transforming growth factor-β1 in 55 cases of breast milk from rural nursery. Methods A total of 55 healthy rural maternity chicks from 5 villages in Chengcheng County, Shaanxi Province were randomly selected. The concentrations of EGF, IGF - Ⅰ and TGF - β1 in breast milk were determined. Results The concentrations of epidermal growth factor, insulin - like growth factor Ⅰ and transforming growth factor β1 in breast milk from 1 to 17 months did not change much (P> 0.05). Conclusions Epidermal growth factor, insulin - like growth factor Ⅰ and transforming growth factor - β1 in breast milk may promote the growth of infants and young children. It is suggested that breastfeeding may be prolonged to 1 year and a half with proper supplementation of supplementary food.
