目的：探讨动态监测B超、β-hCG、孕酮对早期先兆流产预测价值。方法：动态监测380例早期先兆流产患者B超、β-hCG、孕酮的变化，以了解流产的病因并评价预后。结果：318例保胎成功，继续妊娠：62例流产。流产组血清孕酮、β-hCG值低于继续妊娠组，动态检测血清孕酮、β-hCG无升高或升高速度极慢；流产组54例B超发现胚囊变形、胎心消失。结论：B超动态监测、β-hCG、孕酮可作为早期先兆流产预后的评价指标。

英文摘要：

Objective：To evaluate the value of serum β-HCG and progesterone combined with dynamic B- uhrasonography in the diagnosis of early threatened abortion. Methods： The combination of β-HCG,progesterone and dynamic B-ultrasonography were performed in 380 patients with early threatened abortion. Results： 318 cases of miscarriage were prevented successfully, levels of serumβ-HCG and progesterone were significantly lower in threatened abortion group. Conclusion： The combination of serum β-HCG, progesterone and B-ultrasonography are effective in the diagnosis of early threatened abortion.
