Decalcification of the mitral annulus: surgical experience in 81 patients ［J］.

These women, ages 61, 72 and 74 years, receiving long-term pergolide therapy for Parkinson's disease or restless legs syndrome, had valvular abnormalities strikingly similar to those induced by fenfluramine, ergot derivatives, or carcinoid. All three had severe, unexplained tricuspid regurgitation; two had predominantly right-sided congestive heart failure; and two had moderate aortic and mitral valve regurgitation. Histology revealed surface fibroproliferative lesions with preserved underlying valve architecture. Carcinoid was excluded, and none of the patients had taken anorectic drugs or ergots other than pergolide.

这3位妇女年龄分别为61、72及74岁，都长期服用pergolide来治疗帕金森氏症或睡眠脚动症，而且也都有不明原因的严重三尖瓣闭锁不全，就像因fenfluramine、麦角衍生物，或类癌肿瘤所引起的瓣膜异常情形一样；其中2位主要有右心衰竭，2位有中度的主动脉及二尖瓣的闭锁不全，组织学检查显现表面有纤维增生性的损伤，但瓣膜的结构仍然还在；类癌是被排除在外的，而且这3位妇女除了pergolide之外，都不曾服用过厌食剂或麦角类药物。

Based on the model of round axial symmetry turbulent jet, three simplified categories of the mitral regurgitant jet were proposed.

通过Field II软件模拟了二尖瓣返流的各种情况，建立了相应的返流数学模型和返流评价标准。

The valve replacement with partly or whole mitral valve structure can improve the ventricular internal diameter, ejection fraction, cardiac index and stroke volume, thus improving cardiac function. However, bicuspid valve restenosis should be avoided through active observation.

保留部分或全部二尖瓣结构的瓣膜置换能更好地改善左心室内径大小、射血分数、心指数、每搏输出量，从而改善心脏功能，但要积极观察以避免出现二尖瓣再狭窄。

A thorough family history should be taken because many cardiac disorders （eg, coronary artery disease , systemic hypertension, bicuspid aortic valve, hypertrophic cardiomyopathy, mitral valve prolapse） have a heritable basis.

很多心脏疾病（如冠状动脉疾病、全身性高血压、二叶主动脉瓣疾病、肥厚型心肌病、二尖瓣脱垂）都有遗传基础，因此应收集详尽的家族病史。

Congenital heart disease ; Mitral insufficiency ; Mitral valvoplasty

先天性心脏病；二尖瓣关闭不全；二尖瓣成形术

Two (8%) patients ultimately required mitral valve replacement for recurrent mitral insufficiency.

最初手术的10例患者与后15例患者比较，后者耗时明显缩短：总手术室停留时间分别为318.5分钟和275.1分钟；夹闭时间，97.6对81.1分钟；后瓣切除或修补26.2对15.6分钟；瓣膜成形术，31.9对24.8分钟；住院天数分别为4.2和1.67天。5例患者术后出现房颤，2例患者（占8%）因最终出现二尖瓣功能不全而进行了瓣膜置换术。

Mastering the pathophysiology, clinical manifestations and diagnosis of rheumatic valvular disease such as mitral stenosis, mitral insufficiency, aortic stenosis and aortic insufficiency ; generally understanding surgical methods.

掌握先天性心脏病动脉导管未闭，房间隔缺损，室间隔缺损，法洛四联症，主动脉缩窄的概念，病理生理；了解这几种先天性心脏病的病理分型，临床表现，诊断及治疗。

The percutaneous mitral clip repair will find its place in the treatment armamentarium for mitral regurgitation, but several aspects of the study design raise questions, according to Dr. J. Scott Millikan, a cardiothoracic surgeon in Billings Montana.

来自蒙大拿州比林斯的心胸外科医师 Scott Millikan 博士表示，经皮二尖瓣夹合器修补将会在众多二尖瓣关闭不全疗法中找到自己的位置，但该研究设计的几个方面存在问题。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
