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

静脉药物配置中心的建立在临床中的应用

静脉输液药物集中配置、管理是我国医院管理的一项新举措.长期以来,临床静脉输液中的加药工作一直是由护士在治疗室独立完成,这种方式存在着很多不足之处.在这种环境污染下,职业健康安全管理越来越受到各国政府的重视.为了提高服务质量,预防和控制可能存在的环境污染及职业健康安全风险,国家颁布 GB/T24001～ 1996<环境管理体系规范和使用指南>, GB/T28001-2001<职业健康安全管理体系规范>标准,引进国外的先进管理模式,此项工作由药师和护士共同完成,以期达到合理用药减少药物的流失和浪费,科学配置、降低输液反应.静脉药物配置中心把静脉药物配置从普通环境的治疗室转为在具有洁净条件的配置中心进行集中管理配置,保证配置出来的药品安全无菌、有效.需要输液的患者在舒适、整洁和安静的环境下进行输液,减少临床护理工作量的目的,把更多的时间还给病人.这为顺利实施静脉配置中心的项目提供了保障,确保了输液中心正常运行.     

水泥型羟基磷灰石人工骨的制备及性能分析

Objective: To prepare hydroxyapatite cement (or calcium phosphate cement,CPC) and analyze its capability. Methods: Tetracalcium phospluge (TTCP ) was prepared by the method of high heat. TTCP reacted with in simulated body situation and produced CPC. Its capability was analyzed by scanning electron microscopy ( SEM), X-ray diffraction( XRD). Its density, absorbing water coefficient, macroporosity and compressive strength were measured also. Results: The main element of CPC is hydroxyapatile (HA), its microstructure comprised of petal crys-tals. The diameter of micropore was 4-10μm, density was 1. 922 g/cm^3, macroporosity was 29. 777%, absorbing coefficient was 15. 503%, compressive strength was 42.70 Mpa. Conclusion: This CPC has three-dimensional spatial structure, its strength meets the need of cancellous bone grafting.     

水泥型羟基磷灰石人工骨的制备及性能分析(英文)

目的:制备水泥型羟基磷灰石人工骨,并进行性能分析。方法:高温法制备出磷酸四钙,然后在模拟体内环境下将其与无水磷酸氢钙发生水化固化反应,合成水泥型羟基磷灰石人工骨,采用X线衍射、扫描电镜观察、体积密度、吸水率、孔隙率及耐压强度测量进行性能分析。结果:该人工骨主要成分为低结晶度的羟基磷灰石;微观结构呈针状或花瓣状晶体构成,微孔直径约4-10 μm,孔隙相互交通;平均体积密度为1.922 g·cm~(-3);平均吸水率为15.503％;孔隙率为29.777％;耐压强度为42.70 MPa。结论:本研究所制人工骨具有三维空间结构,力学性能符合人体非负重骨植骨要求。     

水稻亚种间杂种优势利用研究

本试验探讨了华南双季稻区利用亚种同杂种优势的特点和问题,结果表明:当前,两系亚种问杂种一代主要存在的问题是结实率低和谷草比低;籼粳交杂种易受环境条件的影响;每穗实粒数和单株有效穗数是决定单株产量的重要因子;每穗实粒数增加的关键在于结实率的提高,本文还就提高结实率和谷草比等问题提出了意见。     

A Biomechanical Double Sac (Pericardium-Pebax) for Specially Shaped Artificial Ventricles: A Computerized Study to Evaluate Its Mechanical and Volumetric Properties

Abstract: For original ovoid shaped artificial ventricles. a biomechanical double sac consisting of a biological sac (porcine pericardium) as the blood contact interface and a synthetic sac (Pebax 3533) as the mechanical support to assume systolic-diastolic dynamic constraints was conceived. The volumetric and mechanical properties were assessed with a three-dimensional modeling of Pebax sacs and computerized simulations of their systolic distortions for both right and left ventricular configurations. The stresses and strains of these sacs were represented as quantitative mappings for a maximum end-systolic state and were below the respective threshold values above which the Pebax material is jeopardized for permanent structure impairment. After fatigue tests applied on Pebax strips under the alleged working conditions of Pebax sacs, the material structure was unchanged and maintained its intrinsic mechanical properties. The theoretical maximum stroke volumes were 74.4 cm³ and 62.4 cm for the left and right ventricular configurations, respectively. With these mechanical and volumetric features, the biomechanical double sac concept was considered valid and could be provided for a consequent specific total artificial heart.
