National Study of Emergency Department Visits for Acute Exacerbation of Chronic Obstructive Pulmonary Disease, 1993–2005

Objectives: Little is known about recent trends in U.S. emergency department (ED) visits for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) or about ED management of AECOPD. This study aimed to describe the epidemiology of ED visits for AECOPD and to evaluate concordance with guideline‐recommended care. Methods: Data were obtained from National Hospital Ambulatory Medical Care Survey (NHAMCS). ED visits for AECOPD, during 1993 to 2005, were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD‐9‐CM) codes. Concordance with guideline recommendations was evaluated using process measures. Results: Over the 13‐year study period, there was an average annual 0.6 million ED visits for AECOPD, and the visit rates for AECOPD were consistently high (3.2 per 1,000 U.S. population; P_trend = 0.13). The trends in the use of chest radiograph, pulse oximetry, or bronchodilator remained stable (all P_trend > 0.5). By contrast, the use of systemic corticosteroids increased from 29% in 1993–1994 to 60% in 2005, antibiotics increased from 14% to 42%, and methylxanthines decreased from 15% to <1% (all P_trend < 0.001). Multivariable analysis showed patients in the South (vs. the Northeast) were less likely to receive systemic corticosteroids (odds ratio [OR] = 0.6; 95% confidence interval [CI] = 0.4 to 0.9). Conclusions: The high burden of ED visits for AECOPD persisted. Overall concordance with guideline‐recommended care for AECOPD was moderate, and some emergency treatments had improved over time.     

改良低压回肠代膀胱术的疗效评价

目的 总结改良原位低压回肠代膀胱术的疗效及患者生活质量。方法 膀胱癌患者53例，平均年龄61岁，均施行根治性膀胱全切术。截取末端35—45cm回肠，“U”形缝合形成代“膀胱”，并与输尿管形成抗返流的“乳头”缝合。结果 术后所有患者血生化及电解质均正常，随访3—6个月，51例患者白天完全可控排尿，完全夜间可控制排尿25例。47例无残余尿，5例有残余尿20-35mL。结论 改良低压回肠代膀胱术，膀胱容量大、压力低、无返流、效果好、无吸收性酸中毒，患者白天均能够控制尿液，夜间需定时排尿，生活质量高，多数患者满意。

急性心肌梗死患者睡眠质量的临床研究

目的 对急性心肌梗死（Acute Myocardial Infarction，AMI）患者睡眠状况进行观察，研究其规律性及与心肌梗死发生、转归的关系。方法 对75例AMI患者分别进行睡眠质量观察和评估。结果 AMI患者按睡眠质量总分分组后，高得分组（≥5．06分，40例）的平均住院时间、梗死面积、合并症数目均明显高于低得分组（〈5．06分，35例），而低得分组的日常生活能力得分却明显高于高得分组（P〈0．05）。结论 AMI患者有明显的睡眠质量下降，并影响其梗死面积、合并症、日常生活活动能力和住院时间。     

Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009     

绝经后骨质疏松症中药治疗研究文献的质量评价

目的 了解目前国内中药治疗绝经后骨质疏松症的临床治疗研究的现状。方法 对检索到的50篇有关中药治疗绝经后骨质疏松症的临床研究论文，按照牛津循证医学中心证据水平标准和临床试验的没计原则，从诊断标准、纳入和排除标准、组间基线可比性、随机、对照、双盲、统计学方法、疗效判断、疗程及药物的不良反应、随访等多个方面进行分析评价。结果 50篇相关文献中，按照牛津循证医学中心证据水平标准评价，推荐级别为B级的占44.0％，C级的占56.0％；证据水平为2b级的占40.0％，3b级的占4.0％，4级的占56.0％；随机对照试验文献占44.0％；临床对照试验文献占4.0％；采用随机双盲者占9.1％，随机单盲者占18.2％，说明组间基线可比的占31.8％，有诊断标准的占90.9％，有纳入和排除标准的占86.4％，说明统计方法的占52.4％，有客观疗效评价指标的占90.9％，说明药物不良反应的占9.1％。结论 有关中医药治疗绝经后骨质疏松症的临床研究论文日益增多，但随机对照试验比例偏低，研究设计及论文撰写水平有待进一步提高。     

体外循环质量管理体系在心脏手术中的应用

目的 探讨心脏手术期间体外循环质量管理的定量评价方法。方法 将可控的生理指标作为体外循环质量目标管理的基础，分析体外循环质量变化的规律，确定体外循环的质量水平与围手术期恢复之间的关系。结果 体外循环质量管理控制项目得分与住院费用呈负相关，R=-0．446，P=0．001，与呼吸机使用时间及ICU停留时间呈负相关，R分别为-0．412、-0．463，P分别为0．041、0．02。呼吸机使用时间与ICU停留时间呈正相关，R=0．06，P=0．001。成人得分偏低的项目是血液稀释不足和静脉混合血氧饱和度偏高，儿童得分偏低的项目是尿量不足、静脉混合血氧饱和度偏高。结论 该体系可以用于心脏手术期间体外循环质量管理的定量评价。
