Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

本论文研究的目的在于借鉴国外有关医疗废物在立法、执法、法律制度等方面的经验，完善适合我国医疗废物管理的相关法律，提出我国有关医疗废物管理的立法构想，完善各项相关的法律制度，以达到规范医疗废物管理、保护环境、保护人类健康的目的。本论文为完善我国医疗废物管理的立法、执法和法律制度提出初步设想，由于我国有关医疗废物的法律制度规定得太原则、太抽象，通过本论文研究，使得我国医疗废物法律制度更具体、更明确，增强在实践中的操作性，使立法精神充分得到体现。同时可以为我国医疗废物管理工作提供法理依据和决策支持。我国医疗废物管理体制的问题加大了医疗废物治理的难度，立法、执法、监督等方面的完善有利于加强对我国医疗废物的管理；在保障可持续发展的环境安全和人类健康领域也具有理论意义和应用价值。本文共分为四个部分，第一部分说明了我国目前医疗废物管理的现状，介绍了医疗废物的概念、危害、进行管理的必要性、当前我国医疗废物的立法现状和法律制度现状。第二部分介绍了美国、欧盟、日本、韩国关于医疗废物管理的立法概况及对我国医疗废物管理的启示。第三部分指出了我国医疗废物管理存在的法律问题，包括立法问题、执法问题和法律制度问题。第四部分针对我国医疗废物管理存在的法律问题提出了相应的建议。建议要提高立法层次、完善立法内容、加强执法力度、实行生产者负责分类回收的法律制度、集中处置法律制度、惩罚性赔偿制度、经营许可证制度、环境责任保险制度和风险基金制度。

In the "History of the Roman Breviary" by Batiffol, 15, we read: In proportion as the Church in extending itself had grown colder, there had taken place within its bosom a drawing together of those souls which were possessed of the greatest zeal and fervour. These consisted of men and women, alike, living in the world without severing themselves from the ties and obligations of ordinary life, yet binding themselves by private vow or public profession to live in chastity all their life, to fast all the week, to spend their days in prayer. They were called in Syria Monazonites and Parthenae, ascetics and virgins. They formed, as it were, a third order, a confraternity. In the first half of the fourth century, we find these associations of ascetics and virgins established in all the great Churches of the East, at Alexandria, Jerusalem, Antioch, Edessa.

， 15 ，我们读到："在比例作为教会在扩大本身增加了寒冷，有发生在其bosom图纸一起，这些灵魂，其中拥有最大的热情和热潮，这些构成的男人和女人，无论是生活在世界上没有切断自己从关系和义务的普通生活，但自己有约束力的由私人或公共的誓言界人士住在贞节所有他们的生活，快速所有的一周内，用他们的天在祈祷中，他们被称为在叙利亚monazonites和parthenae ，修道和处女，他们形成的，因为它被，第三个命令， confraternity ，在上半年的第四个世纪，我们找到这些协会的修道者和处女成立于所有伟大的教堂东，在亚历山大，耶路撒冷，安提阿，伊得撒"。
