摘　　要：目的应用超声观测胸腺,评价不同喂养方式对婴儿早期胸腺发育的影响。方法42例婴儿按喂养方式不同分成单纯母乳喂养组24例,单纯人工配方奶粉喂养组18例。在出生和4个月时,超声探查胸腺,计算胸腺指数,同时记录婴儿体质情况。结果42例婴儿出生和4个月时胸腺图像显示清晰。两组婴儿的胸腺指数在出生时无明显差异;4个月时,单纯母乳喂养婴儿胸腺指数为26.3±12.0,单纯人工配方奶粉喂养婴儿胸腺指数为20.1±10.6,两组比较有显著性差异(P<0.05)。结论人乳喂养婴儿胸腺发育明显优于人工喂养婴儿,人乳对婴儿早期胸腺的发育有重要影响;超声是监测评价婴儿早期胸腺发育状况有效的方法。Objective To evaluate the effect of feeding pattern on thymus development during the early time of infant by ultrasound. Methods Forty- two infants were divide into two groups according to feeding patterns, breast feeding infants（ n = 24）and formula feeding infants（ n = 18）. The thymus of forty- two infants were assessed by ultrasound at birth and 4 months, the thymus index was calculated, condition of infants constitution was registered. Results The thymus ultrasonic appearances of 42 cases were clear and easily achieved through breast bone at birth and age 4 months. There were no significant differences in thymus index at birth of the two groups. At 4 months the thymus index was 26.3±12.0 in breast feeding group and 20.1±10.6 in formula feeding group, there was significant differences between the two groups（ P 〈 0.05）. Conclusion The development of infants thymus in breast feeding is better than that of formula feeding, and breast feeding has important effect on the development of thymus during the early time of infant. Ultrasound is an effective method to monitor and evaluate the development of thymus during the early time of infant.
