关键词： 血脂检验   临床诊断   检测   多指标  

摘要： 血脂检验是临床重要的检测之一，但由于常规拉网检测需要检测的指标较多，因此耗时较长，成本较大，而许多指标结果对临床诊断并无帮助[1]。从经济、实用性方面进行考虑，分级检测可能更加有价值。本研究对血脂检验中分级检验的作用进行分析，现报道如下。

关键词： 快递服务   合同   格式条款  

摘要： 目前,快递企业飞速发展,实践中快件延时、丢失、毁损现象屡见不鲜,而快递行业普遍使用限制性赔偿条款来应对这些风险,这内容往往被记载于快递单背面的格式条款中,这种赔偿并不能使消费者获得有效补偿,因而纠纷频发,从一定程度上阻碍了电子商务的健康发展。因此,本文从快递服务格式合同概念入手,梳理了快递服务合同格式条款主要表现形式,并分析了格式条款的适用条件,以期能够减少由此引发的诉讼与纠纷。

关键词： 糖尿病   早期肾损伤   尿微量   尿糖   诊断价值  

摘要： 目的探讨糖尿病患者早期肾损伤时采用尿微量和尿糖联合检验方法的作用,从而为疾病的有效诊断提供科学的理论依据。方法以该院在2010年12月—2012年12月收治的100例糖尿病患者作为实验组研究对象,另外随机选取同期健康体检者100例作为对照组研究对象。通过尿微量和尿糖联合检测的方法对两组人群进行检测,对比观察两组的检测结果。结果通过检验发现,实验组糖尿病早期肾损伤患者中尿微量白阳性率为54%,尿糖的阳性率为82%,而在对照组正常人群中均未发现尿糖和尿微量白蛋白阳性者。通过统计学方法进行检验分析,上述两组间的差异具有统计学意义(P<0.05)。结论对于糖尿病患者早期肾损伤时,联合使用尿微量和尿糖的检验方法具有重要的诊断价值,因此,该方法值得在临床上进一步推广和使用。

关键词： Self-report   Misclassification   Biochemical verification   Youth smoking  

摘要： Introduction: In Florida, since 1998, identical survey items have been used to measure youth smoking status for the CDC sponsored state school-based survey and the tobacco control program evaluation telephone survey. The two surveys should parallel one another to track tobacco use. Tobacco items collected in the two surveys closely paralleled one another until recently. Since 2008, data show dramatically divergent youth smoking estimates (e.g., relative differences as high as 50%), which cannot be explained by differences in survey and sampling design. As a first step in detecting misclassification of smoking status, we examined the feasibility of asking youth to self-report their smoking behavior and collect a biological sample, with the expectation that some youth will misreport their smoking status. Methods: Using a cross-sectional population level telephone survey, youth were randomly assigned to one of three groups to test mode effects of collecting biological data with self-reported survey data (n = 303). Results: It showed two groups of youth (those who are not asked for a biological and those asked for a biological with an indirect explanation of its use) had similar response rates and self-reported smoking status, while the third group (biological request with a direct explanation of its use) had a substantially lower response rate and self-reported smoking status. Conclusions: The data show youth who are given an indirect explanation of how biological data are to be used were as likely to self-report their smoking status as youth who were not asked to provide a biological sample.

关键词： 临床微生物检验   感染检测   医院内   介入性诊疗技术   医院感染   发病风险   医务人员   抗菌药物  

摘要： 医院感染是指患者或医务人员在医院内获得的感染,部分医院感染潜伏期较长,患者在离开医院后才发病,但也归属于医院感染的范畴。近年来,由于滥用抗菌药物、激素、介入性诊疗技术,增加了医院感染发病风险,因此医院感染的监测是医院工作的重点。临床微生物检验作为医院感染检测的主要方法,在各个环节中具有举足轻重的作用和地位。

关键词： 专业认证   医学检验专业   教学改革  

摘要： 医学检验是临床医学与医学实验技术相结合的一门学科,是医学领域中不可或缺的重要组成部分。医学检验专业起步晚、发展快,自创办以来便面临诸多困难与挑战,2012年全国医学检验专业本科教育实施大改革后,寻找合理的教学方法、探索本专业未来的发展道路更是当务之急。虽然我国医学专业认证起步不久,但专业认证已成为高等医学教育发展的必然趋势。结合医学检验专业目前面临的问题以及专业认证的特点,对医学检验实行专业认证将有助于保障检验医学教育质量,深化教学改革,实现人才培养与社会需求接轨,促进检验专业走向国际化。

关键词： 食品包装   图形   类别  

摘要： 图形是食品包装视觉构成要素中最重要的组成部分,其可通过创意和构思将相关信息进行有效传达,从而让消费者获得快速的认知。本文根据食品包装中图形的不同艺术表现手法,将其大致分为了摄影图形、插画图形、比喻图形、抽象图形这四种,希望能够对食品包装的设计提供一些的理论依据。

关键词： cross-level analysis   interactions   measurement models   quantitative multilevel research  

摘要： Cross-level interaction effects lay at the heart of multilevel contingency and interactionism theories. Also, practitioners are particularly interested in such effects because they provide information on the contextual conditions and processes under which interventions focused on individuals (e.g., selection, leadership training, performance appraisal, and management) result in more or less positive outcomes. We derive a new intraclass correlation, , to assess the degree of lower-level outcome variance that is attributed to higher-level differences in slope coefficients. We provide analytical and empirical evidence that is an index of variance that differs from the traditional intraclass correlation and use data from recently published articles to illustrate that assesses differences across collectives and higher-level processes (e.g., teams, leadership styles, reward systems) but ignores the variance attributed to differences in lower-level relationships (e.g., individual level job satisfaction and individual level performance). Because and provide information on two different sources of variability in the data structure (i.e., differences in means and differences in relationships, respectively), our results suggest that researchers contemplating the use of multilevel modeling, as well those who suspect nonindependence in their data structure, should expand the decision criteria for using multilevel approaches to include both types of intraclass correlations. To facilitate this process, we offer an illustrative data set and the icc beta R package for computing in single- and multiple-predictor situations and make them available through the Comprehensive R Archive Network (i.e., CRAN).

关键词： Dust sample   Sample preparation   Classification   Heavy metal contamination  

摘要： Information on the size dependence of the concentration of pollutants in fine-grained residues is required for the design of classification processes for their processing. For such an analysis, the samples have to be classified prior to chemical analysis. Depending on the particle size range of the residue, a classification method has to be selected. For very fine material, air classification is a suitable method. In this work, the results of the classification of fly ash from a biomass combustion plant with an air classifier are discussed with respect to the observed sample contamination. The chemical analysis of the produced size classes for heavy metals yielded unexpected results. For most heavy metals, the mass balance resulted in a recovery rate of about 100 %;however, for Cr and Ni, the recovery rate was way above 100 %. A more detailed analysis of the data revealed that the ratio of the excess of Cr to Ni in the fly ash was nearly the same as the ratio of Cr to Ni in the material of parts of the classifier. Therefore, erosion of some material from the classifier can be assumed to have caused the contamination of the sample. For the classification of samples, which have to be analysed for Cr and Ni, a classifier has to be used which is made of a material other than stainless steel.
