"For patients with discrete lesions in saphenous vein bypass grafts, the use of DES reduces short-term angiographic restenosis," said Sheldon Goldberg, MD, of Hahnemann University Hospital, Philadelphia."These results cannot be extrapolated to patients with larger grafts, restenotic lesions total occlusions."

菲律宾Hahnemann大学医院的Sheldon Goldberg说，"对局限的大隐静脉桥血管病变患者DES 可以显著降低造影再狭窄，这一结果不能推广到较大移植桥血管、再狭窄或完全闭塞病变。"

Helical CT angiography provides a means to rapidly and noninvasively evaluate the vasculature, both intracranially and extracranially, in acute, subacute, and chronic stroke settings and thus to provide potentially important information about the presence of vessel occlusions or stenoses.

螺旋CT血管成像（helical CT angiography， helical CTA）可以快速、无创地评价急性、亚急性、慢性卒中时颅内及颅外血管状况；因此，可以提供血管闭塞或狭窄的信息。该技术用于急性卒中患者的可行性已被证实。

It shows in clinic as tooth sensitivity, pulpitis,periodontitis,food impaction ,deformation of basifacial caused of loss of occlusal height, temporomandibular disorder syndrome, etc. The wear property of artificial tooth material will lead a direct effect to restoration result, when it exists in oral environment. It will cause tooth enamel loss too much in a very short period, if the wear property of artificial tooth superior to tooth enamel; but if it is inferior to tooth enamel, serious wear will occur on restoration occlusions, which will lead to loss of bite functions and even decrease of occlusal vertical dimension, disorder of bite functions, etc. Therefore, it is important to artificialtooth material not only it"s biotic compatibility, mechanical function, chemistry property but also it"s wear property.

当口腔中存在修复体时，人工牙材料的磨耗性能也直接影响临床修复的效果，当其磨耗性能强于天然牙釉质门时，将会引起天然牙釉质过度磨耗；当其磨耗性低于天然牙釉质时，又会在较短时期内引起修复体咬合面磨损过度，失去咬合功能，严重者甚至出现咬合垂直距离降低，咬合功能紊乱等症状因此，对于人工牙材料除了考虑生物相容性、机械性能及化学性能外，还应考虑到材料的磨耗性能，而磨耗率的测定一直是评价天然牙及人工牙磨耗性能的优越指标之一。

Objective:To evaluate the efficiency and safety of the Amplatz thrombectomy divice in acute thromboembolic occlusions of iliofemoral veins.

目的：评价Amplatz血栓消融器在急性下肢深静脉血栓形成介入治疗中的效用和安全性。

Methods: Fourteen patients of infraocclusion which was caused by defect of dentition or excessive abrasion with temporomandibular internal derangement were choosed, transitional prosthesis were applied to hoist the occlusions.

选取14例因牙列缺损或重度磨耗所致低位咬合同时伴有颞下颌关节结构紊乱患者，采用暂时性修复体升高咬合，3个月后待症状缓解行永久性修复治疗，治疗完成3个月后复查。
