目的：将脐动脉血流速度波形多普勒测量的ＵｍＡＦＶＷＡ／Ｂ值和血清人胎盘泌乳素（ＨＰＬ）的结果结合分析，以期仅通过１２次检查来评估胎盘功能和出生儿结果好、坏．方法：对５０例正常和４０例高危妊娠做了ＵｍＡＡ／Ｂ和ＨＰＬ测定．结果：非连续性测定时Ａ／Ｂ和ＨＰＬ值大小变化相关不显著，ｒ＝－００６－０５３，Ｐ＞００５；高危妊娠中，Ａ／Ｂ，ＨＰＬ异常者多于正常组；Ａ／Ｂ升高，ＨＰＬ降低可同时检出，而在正常组和出生儿正常的高危妊娠中均未能见到此种改变．结论：两项检查同时异常者可伴有出生儿结果不良，敏感度虽较低，约５８３％，但特异度和阳性预期值均达１０００％，较Ａ／Ｂ或ＨＰＬ单独使用时高 OBJECTIVE: To analyze the relationship between UmAFVWA / B measured by Doppler waveforms of umbilical artery blood flow and serum human placental prolactin (HPL), so as to evaluate placental function and birth outcomes only by 12 tests. Methods: UmAA / B and HPL were measured in 50 normal and 40 high risk pregnancies. Results: There was no significant correlation between the changes of A / B and HPL in the non-continuity test, r = -006-053, P> 005. Among the high-risk pregnancies, there were more abnormal A / B and HPL than normal Group; A / B increased, HPL decreased can be detected at the same time, but in the normal group and normal high-risk pregnancies are not seen in such changes. CONCLUSIONS: The two tests with abnormalities may be associated with poor outcome in infants. Although the sensitivity is low at 583%, the predictive value of specificity and positive predictive value were both 1000%, which were lower than those of A / B or HPL alone High
