浅析高校图书馆报纸的人文管理

报纸是一种形式普及、内容广泛、报道及时的信息资源,是研究某一地区、某一国家,特定历史时期社会状态不可或缺的文献资料。对报纸实行人文管理不仅仅是高校图书馆提高自身水平的要求,也是报纸自身特点的要求,更是满足广大师生对信息收集的要求。如何针对性地满足读者的各种信息需求,加大对报纸人文管理和利用,是高校图书馆最根本的职责。     

现代女性视角的人文关注——论中国现代女作家对西方人文精神的审视和接受

中国现代文学是在全面、广泛接受外来影响的背景下产生和发展起来的,无疑,中国现代女作家的创作也受到了外来的冲击。但相比现代男作家,女作家对外来文学的审视有着自己独特的视角。她们关注并接受了西方女性人文主义,对女性自身的命运充满了关切和同情,明显带有女性意识。这些特点鲜明地体现在中国现代女作家的创作中,并影响到当代女作家的创作。     

ASVCP guidelines: quality assurance for portable blood glucose meter (glucometer) use in veterinary medicine

Portable blood glucose meters (PBGM, glucometers) are a convenient, cost effective, and quick means to assess patient blood glucose concentration. The number of commercially available PBGM is constantly increasing, making it challenging to determine whether certain glucometers may have benefits over others for veterinary testing. The challenge in selection of an appropriate glucometer from a quality perspective is compounded by the variety of analytic methods used to quantify glucose concentrations and disparate statistical analysis in many published studies. These guidelines were developed as part of the ASVCP QALS committee response to establish recommendations to improve the quality of testing using point‐of‐care testing (POCT) handheld and benchtop devices in veterinary medicine. They are intended for clinical pathologists and laboratory professionals to provide them with background knowledge and specific recommendations for quality assurance (QA) and quality control (QC), and to serve as a resource to assist the provision of advice to veterinarians and technicians to improve the quality of results obtained when using PBGM. These guidelines are not intended to be all‐inclusive; rather they provide a minimum standard for management of PBGM in the veterinary setting.     

Evaluation of transpulmonary ultrasound dilution cardiac output in piglets: accuracy,precision and trending ability with room temperature injectate

ObjectiveTranspulmonary ultrasound dilution (TPUD) is a minimally invasive technique to measure cardiac output (CO) using a 1 mL kg^–1 isotonic 37 °C saline injectate indicator. The objective was to evaluate the performance of TPUD using a room temperature saline injectate.Study designProspective experimental trial.AnimalsA total of seven anesthetized male Yorkshire piglets.MethodsPiglets aged 1 month and weighing 7.7–9.0 kg were anesthetized with detomidine–ketamine–hydromorphone–isoflurane and a pulmonary artery flow probe (PAFP) placed via a median sternotomy. The thoracic cavity remained open during measurement of CO by PAFP and TPUD. The TPUD indicators of 1 mL kg^–1 0.9% saline at 37 °C and 20 °C were compared during infusions of phenylephrine and dobutamine, blood withdrawal and replacement. Bias, limits of agreement (LoAs) and percentage error (PE) between each iteration of PAFP and TPUD were measured with Bland–Altman plots. Trending ability via concordance, angular bias and radial LoA were compared.ResultsBland–Altman plots showed negligible bias with varying LoAs. PEs of 22% and 38% were found for 37 °C and 20 °C saline injectates, respectively. In the four-quadrant plots, the concordance rate was 94% and 100% for measurements obtained with 37 °C and 20 °C saline injectates, respectively. Angular bias for both were < ±5 °, with radial LoA < ±7 °.ConclusionsTPUD was accurate when using 1 mL kg^–1 of isotonic saline at 37 °C in a range of CO within 0.2–0.8 L minute^–1, and it reliably tracked positive and negative changes in CO. Room temperature (20 °C) indicator was less accurate but equally able to track direction of changes in CO.Clinical relevanceThe use of room temperature injectates allows an easy, readily available clinical application of TPUD CO monitoring while preserving the trending ability of the monitor.
