不同喂养方式对足月新生儿血清瘦素水平的影响

目的比较不同喂养方式对足月新生儿血清瘦素水平的影响。方法选择河北医科大学第一医院产科出生的健康足月新生儿66例,其中母乳喂养儿35例,人工喂养儿31例。在66例新生儿出生第3、7、28天采集母乳2mL于洁净试管中;于新生儿出生第7天,抽取其清晨空腹静脉血2mL,留取血清标本装洁净试管,均置于-70℃冰箱保存。配方乳采用雀巢力多精奶粉,按1匙奶粉加30mL水的比例冲调,水温为50℃。采用放射免疫法对足月新生儿血清、母乳及配方乳中瘦素水平进行测定。结果1.健康足月儿66例出生第3、7、28天母乳瘦素水平分别为(1.31±0.67)μg·L-1、(1.33±0.14)μg·L-1、(1.26±0.98)μg·L-1,不同时间母乳瘦素水平比较差异无统计学意义(F=1.78,P>0.05)。配方乳中未检测到瘦素。2.母乳喂养组新生儿出生第7天血清瘦素水平为(3.38±1.54)μg·L-1,人工喂养组新生儿出生第7天血清瘦素水平为(1.91±0.32)μg·L-1,二组血清瘦素水平比较差异有统计学意义(t=3.176,P<0.05)。结论母乳中含有一定水平的瘦素,是新生儿血中瘦素的重要来源。母乳喂养有利于维持新生儿期血...

Effect of Different Feeding Practices on the Serum Leptin Levels in Full Term Neonates

Objective To compare the effect of different feeding practices on the serum leptin levels in full term neonates.Methods Venous blood samples about 2 mL were obtained from 66 cases of 7 day-old healthy full term neonates,35 cases of them were breast-fee-ding,and 31 cases of them were formula-feeding.On the 3rd,7th,28th days of the 66 neonates after delivery,breast milk samples about 2 mL were drawn.And on the 7th day,venous blood about 2 mL were drawn in the morning at the fasting state.The serum and breast ...
