妊娠高血压综合征（PIHS）是常见的妊娠合并症，是导致孕妇和围产儿死亡的重要原因。近年，已有许多预测好高征的方法[1]，但均有一定的局限性。我们测定了276例孕中期血β－hCG含量、平均动脉压（mABP）、尿钙含量及Ca／Cr比值，以冀探讨4项指标联合检测用于预测妊高征的价值 Pregnancy-induced hypertension (PIHS) is a common complication of pregnancy, an important cause of death in pregnant women and perinatals. In recent years, there are many methods for predicting good symptoms [1], but all have some limitations. We measured 276 cases of second trimester blood β-hCG levels, mean arterial pressure (mABP), urinary calcium and Ca / Cr ratio in order to explore the four indicators combined detection of the value of the prediction of pregnancy-induced hypertension
