Periodically measure both groups’ ?-HCG, test the mass reduction with B ultrasonic exam. [Result] For the study group, the cure rate was 91.2%; 83.3% for the control one, without statistical meaning; the ?-HCG negative rate and mass reduction rate were better in study group than the control one, with marked difference; moreover, the study group had less side effect, less in-hospital time.
