目的：建立人侵蚀性葡萄胎裸鼠皮下移植瘤模型，探讨其生物学特性。
Objective: to establish subcutaneous transplanted model of human invasive mole in nude mice and to explore their biological properties.
结论：CDFI对侵蚀性葡萄胎的诊断以及观察其疗效是一个非常有价值的方法。
Conclusion: CDFI is a useful method in the diagnosis of invasive hydatidiform mole and in monitoring the tumor response to chemotherapy.
方法运用扫描电镜技术观察葡萄胎90例（良性6 0例，侵蚀性30例） ，以10例正常早期胎盘绒毛作对照。
METHODS SEMT was performed to observe 90 cases with hydatidiform moles (60 cases with benign and 30 cases with invasive hydatidiform moles) and 10 cases with normal placental villis as the control.
