1、妊娠中期测定孕妇血清β-HCG、AFP及UE3水平对预测妊高征的意义【摘要】目的探讨测定中期妊娠孕妇血清β-HCG、AFP及UE3水平及测定MAP对预测妊高征的关系。方法对2363例中期妊娠孕妇抽取血标本测定血β-HCG、AFP及UE3值,同时测量MAP,并随访至分娩,观察上述指标与妊高征的关系。结果有177例因各种原因除外后,余2186例随访至分娩,发生妊高征179例,占8.2%。妊高征组血β-HCG、AFP值分别为(61.75±9.78)IU/L及(328.3±41.52)μg/L,显著高于正常孕妇组的(20.65±7.61)IU/L及(15
2、1.96±36.06)μg/L,P<0.01。UE3为(53.7±20.11)ng/L,显著低于正常组的(81.45±34.36)ng/L,P<0.05。当血β-HCG升高≥2MOM,AFP值升高≥2.5MOM时,预测妊高征发生率分别为39.8%(45/125)及29.8%(42/141),显著高于对照组的6.3%(134/2090)及6.4%(137/2045)。UE3下降≤0.5MOM时预测妊高征发生率为29.8%(42/141),显著高于对照组的6.7%(137/2045)。当MAP>12kPa时,预测妊高征发生率为26.
3、4%(112/425)。在179例妊高征患者中有40例上述四种指标均明显高于预示值水平,且大多为重度子痫前期患者。结论测定中期妊娠孕妇血清β-HCG、AFP及UE3及MAP对预示妊高征发生均有一定价值。当应用多指标联合监测可显著提高阳性预测率。【关键词】中期妊娠;β9-HCG;AFP;UE3;MAP;妊娠高血压综合征;预示[Abstract]ObjectiveToinvestigatetherelationshipbetweenpredictingPIHanddetermingserumβ-HCG,AFPandUE3levelsinmidtrim
