结果：三组完全流产率、孕囊排出时间、出血时间及月经复潮时间差异无显著性；a组妊娠小于6周者完全流产率与妊娠6周～8周者相比差异有显著性；疗程短者出现副反应小，三组差异均有显著性。结论：米非司酮服用时间越短，其胃肠反应与头晕乏力等副作用越小；a组具有用时短、疗效确切、副作用小等优点，尤其对孕周小于6周患者流产效果好。

Nutrition solution culture, ICP-AES, the differential centrifugation technique and sequential chemical extraction method, suppression subtractive hybridization , RAPD were used in this thesis to study the mechanisms of copper tolerance and accumulation by Commelina communis grown in copper mine deposit which was reported to be a Cu hyperaccumulator, compared with C. communis grown in normal soil. Several aspects were examined, including: difference of copper tolerance and accumulation between C. communis grown in copper mine deposit and that grown in normal soil; difference of growth and nutrient accumunation between C. communis grown in copper mine deposit and that grown in normal soil under copper treatment; physiological differences between between C. communis grown in copper mine deposit and that grown in normal soil under copper treatment; subcellular distribution and chemical forms of Cu in C. communis; identification of cDNA fragments differentially expressed in C. communis grown in copper mine deposit; genetic diversity and copper tolerance of C. communis, tolerance mechanisms to copper in C. communis are discussed.
