| 1 | 人类与自然耦合系统显示文摘人类与自然系统不断地相互作用促使人类与自然耦合系统(CHANS)的形成与发展。近期的研究揭示了人类与自然耦合系统在组织、空间以及时间上耦合的复杂性。这些耦合在相互作用方面从直接演化到更间接;在联结方面从邻近演化到更远距离;在尺度上,从局部演化到全球;在模式和过程上,从简单演化到复杂。解开如相互影响和突发属性的复杂性,能够导致新的科学发现,并且对于开发生态和社会经济可持续性的有效政策是非常重要的。以解决关于人类与自然耦合系统的基本问题和迎接社会的空前挑战为目的的,真正整合不同学科的机会正显现出来。 | 刘建国 Thomas Dietz Stephen R.Carpenter Carl Folke Marina Alberti Charles L.Redman Stephen H.Schneider Elinor Ostrom Alice N.Pell Jane Lubchenco William W.Taylor 欧阳志云 Peter Deadman Timothy Kratz William Provencher 张淑敏 | 2007 | AMBIO-人类环境杂志2007，36，B12： | 13 |
| 2 | β-受体阻断剂对门肺高压患者运动能力及血流动力学的不良影响显示文摘Background &Aims: It has been suggested that β-blockers might be harmful in pulmonary arterial hypertension. However, no study has evaluated the effect of β-blockers in these patients. The aim of this study was to investigate the effect of β-blockers on exercise capacity and pulmonary hemodynamics in patients with portopulmonary hypertension receiving β-blockers for the prophylaxis of variceal bleeding. Methods: Ten consecutive patients with moderate to severe portopulmonary hypertension (mean pulmonary artery pressure of 52 [10]mmHg) underwent a 6 minute walk test and a right heart catheterization at baseline and 2 (1) months after β-blocker withdrawal. Results: Following β-blocker withdrawal, 9 of 10 patients increased their 6 minute walked distance with a mean increase in the whole group of 79 (78) meters (P = .01). Cardiac output increased by 28%(P < .01) with no change in mean pulmonary artery pressure, resulting in a 19%decrease in pulmonary vascular resistance (P < .01). Increases in cardiac output were related to a 25%increase in heart rate (P < .01), whereas stroke volume was unchanged (P = .65). The improvements in exercise tolerance were associated with increases in chronotropic response (maximal heart rate minus resting heart rate) from 18 (9) to 34 (12) beats/min (P < .01) during the 6-minute walk test. Conclusions: In patients with moderate to severe portopulmonary hypertension, β-blockers are associated with significant worsening in exercise capacity and pulmonary hemodynamics. These deleterious effects support the contraindication of β-blockers in patients with portopulmonary hypertension. | Provencher S. Herve P.
