Patients’ satisfaction with waiting time and the facilities in eye clinics is an important indication of the patients’ assessment of the quality of service in the eye clinic. In this study, waiting time was defined as time spent from arrival to time when the patient is seen by a doctor. Some factors that affect patients’ waiting time in health clinics include: healthcare setting, availability of adequate resources and personnel, efficient deployment of available resources and competence of healthcare workers, and punctuality of healthcare workers. The physical environment, comfort of patients, and level of infrastructure in the hospital also influence patients’ satisfaction. This observational, descriptive, cross-sectional study was conducted among patients that attended an eye care clinic, in a tertiary hospital, and 348 respondents were interviewed. Most of the respondents were aged 40 years and above (64.4%), females (63.5%), Igbos by tribe (94.8%), married (63.2%), Christians (96.6%), and had at least a secondary level of education (78.4%). Most perceived waiting time as being very long or long (60.1%), and only 48.8 were satisfied or very satisfied with the waiting time. Most also perceived the cleanliness of the eye clinic as being clean or very clean (85.0%), and 70.7% perceived the ventilation as being adequate or very adequate. The majority reported that a health talk was given (71.6%), and 62.7% were satisfied or very satisfied with the talk. More respondents (46.8%) perceived the waiting space as very inadequate or inadequate, as against 43.4% that perceived it as adequate or very adequate. More reported that prescribed drugs were completely unavailable or few available (48.0%), while 42.3% reported drugs as being reasonably or completely available. It is important that management of health facilities that offer eye care services, work towards improving patients’ perception and satisfaction with services provided in the eye clinics.

Intra-tumor heterogeneity in head and neck cancer and its clinical implications

引用

World Journal of Otorhinolaryngology-Head and Neck Surgery 2016年第2期2卷 -页

作者： edmund A. Mroz James W. Rocco Department of 0tolaryngology-Head and Neck Surgery The James Cancer Hospital and Solove Research Institute The 0hio State University Columbus 0H USA

The presence of heritable differences among cancer cells within a tumor, called intra-tumor genetic heterogeneity, has long been suspected of playing a role in poor responses to therapy. Research over the past decade has documented the existence of such heterogene-ity within tumors of individual patients and documented its potential clinical significance. The research methods for identifying this heterogeneity were not, however, readily adaptable to widespread clinical application. After a brief review of this background, we describe the devel-opment of a measure of intra-tumor genetic heterogeneity, based on whole-exome sequencing of individual tumor samples, that could be applied to biopsy specimens in a clinical setting. This measure has now been used in head and neck squamous cell carcinoma (HNSCC) to docu-ment, for the first time, a relation of high intra-tumor genetic heterogeneity to shorter overall survival in a large, multi-institutional study. The implications of heterogeneity for research and clinical care thus now need to be addressed. Copyright a 2016 Chinese Medical Association.

Recurrent thrombotic occlusion of a transjugular intrahepatic portosystemic stent-shunt due to activated protein C resistance

引用

World Journal of Gastroenterology 2005年第32期11卷 5064-5067页

作者： Elmar Siewert Jan Salzmann edmund Purucker Karl Schürmann Siegfried Matern Department of Internal Medicine ⅢAachen University AachenGermany Department of Diagnostic RadiologyAachen University AachenGermany

The transjugular intrahepatic portosystemic stent-shunt (TIPS) has successfully been used in the management of refractory variceal bleeding and ascites in patients with portal hypertension. Major drawbacks are the induction of hepatic encephalopathy and shunt dysfunction. We present a 59-year-old woman with alcoholic liver cirrhosis who received a TIPS because of recurrent bleeding from esophageal varices. Stent occlusion occurred 4 mo after placement of the TIPS. Laboratory testing revealed resistance to activated protein C (APC). Combination therapy with low-dose enoxaparin and clopidogrel could not prevent her recurrent stent occlusion. Finally, therapy with high-dose enoxaparin was sufficient to prevent further shunt complications up to now (follow-up period of 1 year). In conclusion, early occlusion of a TIPS warrants testing for thrombophilia. If risk factors are confirmed,anticoagulation should be intensified. There are currently no evidence-based recommendations regarding the best available anticoagulant therapy and surveillance protocol for patients with TIPS.

LNG设施通常包括天然气液化、LNG储运及运输等。在中国天然气供应链对经济民生影响重大。天然气供应链或供应系统中关键设备的非计划及计划性维修导致的天然气供应中断,都可能造成巨大的经济损失。本项目应用可靠性、可用性及可维修性(RAM)分析方法对于液化天然气储备库及附属设施的可靠性指标进行评估,定量分析LNG供应链中关键设备的失效及维修时间对于整个供应链可靠性指标的影响。RAM分析可以用来预测在指定的运行周期内整个LNG供应链的运行绩效。RAM分析辨识关键设备的失效模式,确定失效数据,并采取Monte Carlo的模拟计算,获得LNG供应链或系统中,关键设备失效对于可靠性指标影响。本文通过国内某LNG储备库项目的 RAM分析,应用以Monte Carlo模拟为基础的系统可靠性分析软件ReliaSuite?,评估LNG储备库系统设计能否满足可靠性指标。并且对LNG储运设施的卸料臂进行了失效模式及关键性影响分析(FMECA)。通过对LNG储备库各子系统对于项目整体可靠性的贡献进行敏感性分析,找到影响项目整体可靠性的瓶颈及解决方案。

为更好了解与试样电火花烧蚀有关的实验现象,我们设计了一种新算法,并报道了其用于测定夹杂物尺寸的结果。在此算法中,用元素氧化物、硫化物和氮化物测量通道的单火花强度分析技术测定了某一特定类型夹杂物中各元素的浓度,包括铝、钙、镁、锰、钛以及硅等。对每个相关通道,计算了指定类型夹杂物有关的强度峰值对应的强度值之和与所有强度值和之间的比值。在光谱化学分析中,此比值与测试浓度相乘,所得结果为指定类型夹杂物中元素的平均浓度。结合单火花烧蚀质量与夹杂物成分的化学计量学分析,可以估算夹杂物的尺寸。通过进一步的分析可以实现夹杂物尺寸(小、中和大级别)的辨别。本方法的创新性在于,单火花源强度既不需要漂移修正也不需要校正。本算法可以直接用于计算钢中大部分常见夹杂物的平均浓度和尺寸的分析,例如氧化物、硫化物和尖晶石。测定结果显示夹杂物的平均直径在1～10μm之间。

The University of Applied Sciences in Vienna has offered university degree programs in the field of construction for more than twenty years and has thus gained great expertise in developing its curriculum. Founded in 1996, the department of Building and Design consists of six university degree programs. A major strength of the department is the possibility to adapt to recent challenges in a timely manner. As shown in Figure 1, in the winter term 2008/2009, the master’s degree program, Sustainability in the Construction Industry, was held for the first time;it was transformed into the master’s degree program, Architecture-Green Building, in 2016. In 2013/14 the bachelor’s degree program, Architecture-Green Building, started with the first students graduating in 2016. For ten years the department has focused on sustainability within the building, planning and designing processes.

Pancreatitis, both acute and chronic, causing the development of acute chylous ascites and peritonitis has rarely been reported in the English literature. This is the fourth published case of acute chylous ascites mimicking acute appendicitis in the literature.

随着人类社会的发展,人口激增,生活垃圾的种类及数量迅速增长,这些生活垃圾侵占了大量土地,污染空气、传播细菌疾病等。城市垃圾治理问题日益突出,城市垃圾治理问题不仅仅影响到城市的环境和生活质量,而且也对城市居民的身体健康产生重要的影响。如何对城市垃圾进行有效地处理,为人们创造一个良好的工作和生活环境,已成为城市管理者长期以来一直困扰而且急需解决的难题。而目前现有的城市垃圾箱不能有效的容纳和管理垃圾,不能有效的解决产生异味等相关环境问题,同时消耗的大量人力和资金。本文针对城市垃圾管理问题,研究设计了一个太阳能智能垃圾箱。依据仿生学,设计灵感来自于木槿花开花原理。整个智能垃圾桶系统依据TRIZ原理进行设计,通过矛盾矩阵以及发明原理解决问题。并提出了垃圾管理自动化的先进方法,其中采用射频识别(RFID)技术,并利用射频(RF)标签和网络支持,该系统包括四个主要子系统,即智能垃圾系统(STS),本地基站(LBS),智能车辆系统(SVS)和智能监控小屋(SMCH)。该系统将能够实现垃圾监测过程的自动化和整个收集过程的管理,以高效和简便的方式处理和处置日常垃圾。基于TRIZ理论对问题的分析和解决,整个智能垃圾箱箱体由12V太阳能变压器供电,箱体配置一个电池和一个灭火器,节能安全。采用LCD屏幕用于显示垃圾箱收集垃圾的状态、指示电源和位置信息。箱体外观可以根据业主需要进行定制,能和谐融入于不同的城市环境。智能垃圾箱能够实现对垃圾的自我管理和实时监控垃圾箱使用状态,便于城市管理合理安排垃圾管理工作,减少人员和时间消耗,节约垃圾管理成本,相较于传统城市垃圾桶更加节能、环保、高效和安全。
