The abvent of the ASOG and UNIFAC group-contribution methods for the prediction of activity coefficients approximately 15 years ago was a significant boost to the ability of chemical engineers to model chemical processes. This paper reviews the status and recent progress in the group-contribution approach to predicting liquid-phase activity *** different types of liquid mixtures arc considered: non electrolyte mixtures with normal-boiling components; mixtures with dissolved gases; mixtures with polymers; and mixtures including strong electrolytes. It is concluded that in recent years much progress has been made in the development of group-contribution models for the prediction of activity coefficients. It is in addition shown that combining activity coefficient models with equations of state renders the group-contribution approach applicable also to the highpressure *** to space limitation, this review emphasizes UNIFAC and related models.

背景和目的颅内动脉粥样硬化可导致众多患者发生缺血性卒中。过去10年里的技术发展使颅内动脉粥样硬化狭窄的血管内治疗成为可能。因颅内动脉粥样硬化狭窄而接受血管成形术或支架辅助血管成形术的患者数量不断增加。鉴于在对血管成形术或支架辅助血管成形术治疗颅内动脉粥样硬化狭窄或闭塞的临床和放射学评价、技术和转归进行报道时，尚缺乏普遍接受的定义，本文的目的是为其报道标准、术语和书面定义提供共识性推荐意见。报道摘要本文是由技术评价委员会、神经介入外科学会、介入放射学学会、美国神经外科医师协会和神经外科医师大会的脑血管神经外科联合分会以及美国神经病学学会卒中和介入神经病学分会组成的联合写作组起草完成的。对1997年1月—2007年12月美国国立医学图书馆文献数据库（PubMed）进行计算机检索，以确定已发表的涉及狭窄性颅内动脉粥样硬化的介入治疗数据，以此作为质量评价的基准。我们设法确定那些可能影响操作成功和并发症风险的危险因素。本文针对颅内动脉粥样硬化狭窄或闭塞的血管内治疗临床试验设计的重要因素，提出了各种临床和技术方面的基本原则。本指南还包含了对这类临床试验统一报道标准的建议。这些定义和标准主要用于研究目的；不过，它们对于临床实践也应有所帮助，并且适用于所有出版物。结论总之，这些建议的定义代表了为构建有效研究数据集的推荐意见。其目的是促进科学而严谨的研究结果的产生，使类似研究之间和内部进行可靠的比较成为可能。在某些情况下，本指南中的一些定义由写作组的专家团队一致推荐，以使报道和发表一致。这些定义应能让不同研究小组发表能够进行直接比较的研究结果。

Background : In many animal experiments, it is vital to detect sudden changes in cardiac output(CO). This porcine study compared CO that was measured with a SwanGanz pulmonary catheter with the gold standard(which was a transit-time flow probe around the pulmonary artery) during interventions that caused hemodynamic *** : In one series, 7 pigs were exposed to sudden changes in CO. In another series, 9 pigs experienced more prolonged changes in CO. All the pigs had a Swan-Ganz catheter placed into the pulmonary artery and a flow probe around the pulmonary artery. Adrenaline infusion and controlled hemorrhage were used to increase and decrease CO, respectively. The measurements of CO before and after each intervention were compared for correlation, agreement, and the time delay that it took each method to detect at least a 30% change in CO. A Bland– Altman test was used to identify correlations and agreements between the *** : In the first series, there was a delay of 5– 7 min for the Swan Ganz catheter to register a 30% change in cardiac output, compared with the flow probe. However,during prolonged changes in CO in the second series, there was a good correlation between the 2 methods. Mixed venous oxygen saturation reacted faster to changes than did CO;both were measured via the Swan-Ganz *** : In many animal studies, the use of Swan-Ganz catheters is suitable;however, in experiments with sudden hemodynamic instability, the flow probe is the most advantageous method for measuring CO.

背景有症状颅内动脉粥样硬化性疾病（intraeranial atherosclerotic disease，ICAD）是全世界范围内最常见的卒中原因之一。研究显示，严重ICAD患者的复发性卒中风险很高，亟需有效的预防手段。药物治疗是治疗ICAD的基础，对所有患者都至关重要。血管内治疗也是一种潜在的治疗选择，但在最佳的技术和患者选择方面仍需进一步探索。本指南旨在为ICAD患者提供诊断和血管内治疗的推荐意见。方法进行文献回顾，以选#2000年至2011年期间发表的有关ICAD的文献。根据美国心脏协会（AmericanHeartAssociation，AHA）庄荚国卒中协会标准对证据进行评估和分类。在神经介入外科学学会标准委员会对现有证据进行评价的基础上制定推荐意见。按照美国神经病学学会（AmericanAcademyofNeurology，AAN）、AHA卒中委员会以及牛津大学循证医学中心（CentreforEvidenceBasedMedicine，CEBM）建议的循证医学指南进行评估。结果总共选定59篇文献。支架置人术与强化药物治疗预防颅内动脉狭窄患者复发性卒中（StentingversusAggressiveMedicalManagementforPreventingRecurrentStrokeinIntracranial＆enosis。SAMMPRIS）研究是现有的唯一一项前瞻性随机对照试验，文献的证据级别被归类为AHA B级、AANⅡ级和CEBM1b级。有症状椎动脉或颅内动脉粥样硬化性疾病支架置人术（StentingofSymptomaticAtheroscleroticLesionsintheVertebralorIntracranialarteries，SSYLVtA）试验是由独立的神经科医生进行转归评价的一项前瞻性非随机研究，文献的证据级别被归类为AHAB级、AANⅢ级和CEBM2级。其他研究均为非对照性或未进行客观的转归评价，因此证据级别被归类为AHAC级、AAHIV级和CEBM4级。结论对于有症状ICAD患者，阿司匹林＋氯毗格雷联合治疗3个月和强化控制危险因素是一线治疗方案。对于经过选择的有症状ICAD患者，球囊血管成形／支架置入术是一种可供选择的治疗方案。需要进一步研究，以确定合适的患者选择标准以及针对各种亚组患者的最佳治疗方案。
