Objective To evaluate the extraoral bow headgear traction on the correction of moderate to high degree of crowding associated with the clinical efficacy of high angle cases. Methods 18 cases of severe crowding dentition in patients with high-angle, high application of headgear traction strengthen teeth extraoral arch anchorage, and a high degree of control teeth, the tooth extraction with fixed appliance treatment. Results 18 patients were aligned dentition, face has been maintained or have a good improvement in molar and canine relations have reached a neutral, maintain or reduce the mandibular plane angle. Conclusion headgear extraoral bow of moderate to severe crowding in high angle cases with the treatment of teeth can play a high degree of control and strengthen the role of molar anchorage.(maybe)

【Abstract】Objectives: To evaluate clinical effect of dental orthodontic as of headgear facebow higher traction on middle to severe crowded dentition with high-angle cases. Methods: 18 patients with middle to severe crowded dentition besides high-angle were applied with headgear facebow higher traction and reinforcement on molar anchorage, while height of molar teeth should be managed and corrective treatment as exodontia combining with fixed appliance. Results: 18 cases got appropriate arrangement, facial forms of such cases remained the same or got well beautified, relation between molar and canine teeth reached middle level and, mandibular plane angle (MPA) kept unchanged or decreased. Conclusions: Treatment with headgear facebow for middle to severe crowded dentition with high-angle cases could manage height of molar teeth and reinforce molar anchorage.【Keywords】headgear facebow, crowded dentition, high-angle供参

Objective To evaluate acute and long2term angiographic and clinical outcomes of longstent or multiple overlapped stents (length ≥ 20 mm) implantation for diffuse atherosclerosis lesions inoctogenarians. Methods Long stent or multiple overlapped stents implantation was performed on 111diffuse native coronary lesions ( Group O : 47 lesions in 44 octogenarians ; Group Y: 64 lesions in 58 patientsaged under 60) . Baseline demographic , lesion characteristic , angiographic and procedural details weresimilar in these 2 groups. Six2month clinical and angiographic follow2up was completed in all cases. In2hospital and long2term outcomes were evaluated. Results Procedure success was 100 %for both had in2hospital major adverse cardiac events (MACE) . There was no significant difference inangiographic binary restenosis ( ≥50 % diameter stenosis) rate between the groups at follow2up ( Group Ovs. Group Y, 1218 % vs1 1019 % at 32month , 2918 % vs. 2616 % at 62month , P > 0105) . The rates oftarget lesion revascularization and MACE at follow2up were less in Group Y, but it showed no statisticalsignificance (718 % vs. 1016 % and 816 % vs. 1114 % at 32month , 1516 % vs. 2314 % and 2017 % % at 62month , respectively , P > 0105) . Conclusions Long stent implantation for diffuse lesionsin octogenarians appears safe and feasible , with high procedural success and favorable long2term outcomes.

医学英文论文摘要的写作方法

1. 论文摘要的作用：     “The function of the abstract of a scientific paper is to provide an overview of the paper so that the readers know the main story and a few essential details of your work without reading the hole text of the paper. The abstract should make sense both when read alone and when read with the paper.” – URMSMJ 1.    摘要的分类： 摘要分为两大类：通报性或指示性摘要（indicative abstract）和报道性或资料性摘要（informative abstract） 1)  指示性摘要：只通报论文主题，不介绍研究的材料、方法和结果，一般用现在时表述。许多专业杂志在其目录页的标题下都有一个指示性摘要，特别是编者认为较重要的一些文章标题后。如：Free transfer of two undamaged fingers from a non-replantable left arm to a mutilated right hand in a 16-month-old boy is reported. （本文报道将一无法再植的左臂上的两个未受损伤的手指移植给一16岁男孩被切断的右手。） 1） 资料性摘要：告诉读者研究的总体情况，使他们了解研究的目的、材料、方法、结果、结论以及存在的问题。资料性摘要分为传统型或非结构式（non-structured）和结构式(structured)两大类型。无论何种形式的摘要，都应包含以下几个基本要素： 1）主题（Main topic as in title) 2）目的（Purpose of research） 3）方法（Methodology） 4）材料（Materials） 5）结果（Results) 6）结论（Conclusions） 非结构式摘要：段落不明，给编辑、审稿、阅读及计算机处理带来诸多不便。 1）全结构式（full-structured）摘要： 1974年4月，加拿大McMaster 大学医学中心的Dr R Brian Haynes首先提出建立临床研究论文的结构式摘要。在 Dr Edward J Huth创导下，美国《内科学记事》（Annuals of Internal Medicine）在国际上率先采用了全结构式（full-structured）摘要。 Haynes所提出的全结构式摘要包含8个要素： 1．目的（Objective）：说明论文要解决的问题 2．设计（Design）：说明研究的基本设计，包括的'研究性质 3．地点（Setting）：说明进行研究的地点和研究机构的等级 4．对象（Patients' participants or subjects）：说明参加并完成研究的病人或受试者的性质、数量及挑选方法 5．处理（Interventions）：说明确切的治疗或处理方法 6．主要测定项目（Main outcome measures）：说明为评定研究结果而进行的主要测定项目 7．结果（Results）：说明主要客观结果 结论（Conclusion）：说明主要结论，包括直接临床应用意义与非结构式摘要相比，全结构式摘要观点更明确（more explicitness），信息量更大（more information），差错更少（fewer errors），同时也更符合计算机数据库的建立和使用要求。但其缺点也是显而易见的，即烦琐、重复、篇幅过长' 而且不是所有研究都能按以上8个要素分类的。于是更多的杂志扬长避短，采用半结构式（semi-structured）摘要。 1）半结构式(semi-structured)摘要：半结构式摘要也称为四要素摘要，包括：目的（objective/purpose/aim）、方法（methods）、结果（results）和结论（conclusion）采用何种摘要形式要根据各杂志的具体要求而定。目前国内许多杂志正从非结构式摘要向半结构式摘要过度。 3．摘要中时态的应用： 我们在Unit One 讨论了论文中时态应用的基本原则。这些基本原则同样适用于摘要的写作中。1）目的部分：背景介绍：一般现在时或现在完成时目的说明：一般现在时/现在完成时，或一般过去时2）材料、方法和结果部分：除指示性说明外，一律用一般过去时。过去完成时只用于说明研究前的情况或研究中某一点时间之前发生的情况' 上文半结构式摘要示例中“At the end of pregnancy' the hypothysis had increased in vertical' anteroposterior' and transverse dimensions'…” 便是一例。3）结论部分：凡陈述研究的材料、方法和结果时，一律用过去时；分析结果或发现的原因时，或者提出结论性意见时，如果作者认为具有普遍意义，可用现在时；如果作者认为自己的分析或结论只限于本研究范围或者仅是一种可能性，则用一般过去时为好
