背景:国家指南推荐伴有外周动脉疾病(PAD)的冠状动脉疾病患者采取二级预防。然而既往PAD对急性冠状动脉综合征(ACS)患者的治疗和预后的影响尚不完全清楚。本研究旨在评估有既往PAD的ACS患者的治疗和院内预后。方法:分析1999—2004年间进行的大型、多国参与GRACE研究资料,该研究包括41108例年龄≥18岁的ACS患者。结果:41108例患者中,4003例(9.7%)既往曾患有PAD。

社区冠心病死亡率的变化趋势

世界核心医学期刊文摘（心脏病学分册） 2006年第6期2卷 24-25页

作者： goldberg R.j. Glatfelter K. Burbank- Schmidt E. 赵君 Division of Cardiovascular Medicine Department of Medicine University of Massachusetts Medical School 55 Lake Avenue North Worcester MA 01655 United States Dr.

Background: Relatively little data are available, particularly from the more generalizable perspective of a population- based investigation, describing recent trends in death rates due to coronary heart disease(CHD). The objectives of this observational study were to describe changes over a twelve year period(1990- 2001) in death rates due to CHD and acute myocardial infarction(AMI) in residents of the Worcester, Massachusetts, metropolitan area(2000 census=478,000). A secondary study goal was to describe changes in death rates attributed to CHD over time separately in men and in women, in persons of different ages, and according to location of death. Methods: Death datatapes were obtained from the Massachusetts Department of Public Health for greater Worcester residents who died over the period 1990 to 2001. Results: Marked declines were observed in the population death rates(per 100,000) due to CHD(1990 death rate=322; 2001 death rate=224) and AMI(1990 death rate=137; 2001 death rate=87) in the greater Worcester population. Declines in the annual death rates attributed to CHD were observed in both the hospital(4.4% decline) and out- of- hospital setting(1.6% decline) as well as for patients dying from AMI(annual declines of 4.8% and 1.9% respectively). Reductions in CHD death rates over time were observed in men and in women and in persons of all ages. Conclusions: The present results demonstrate encouraging declines in community death rates due to CHD and AMI over time and the impact of evolving primary and secondary prevention efforts.

In arbitrary Riemannian 4-spaces, continuity equations are constructed which could be interpreted as conservation laws for the energy and momentum of the gravitational field. Special attention is given to general relativity to obtain, of natural manner, the pseudotensors of Einstein, Landau-Lifshitz, Moeller, goldberg and Stachel, and also the conservation equations of Komar, Trautman, DuPlessis and Moss.

目的研究喉全切除气管断端膜样部食管吻合分流发音重建术的长期疗效.方法利用自制的随访表,对白求恩国际和平医院48例患者做长期随访,其中喉癌行喉全切除发音重建术46例,下咽癌行喉全切除发音重建术2例.观察他们的发音和吞咽情况,并对手术并发症和生存率做了统计分析.结果 35例无喉者的言语水平接近正常喉言语水平,他们的最大发音时程较长、听距较远、言语可懂度高、较流利.5例发音效果较差,但言语可懂度仍高.发音成功率83.3%(40/48).成功组中,40.0%无喉言语者(16/40)有不影响正常进食的轻微误吸.另8例不能发音,也没有误吸.气管瘘口、气管-食管分流口感染和咽瘘是影响发音重建成功的重要因素.生存率与单纯喉全切除术相当.结论该术式一期完成,操作简单,发音成功率高,一些病例虽有轻微误吸,但不影响正常进食,值得推广运用.
