摘要： 检验是通过各种手段配合仪器对排泄物、分泌物、呕吐物、血液、体液和脱落细胞进行检测化验.检验报告从一个侧面反映了病人的病情变化,是临床诊疗的重要参考依据.检验报告是护士解决护理问题的重要参考信息.[1]要得到一份准确的检验报告,除了检验科自身的软硬件以外,护理工作在这中间起着非常重要的作用[2].由于传统的医护分工,检验报告在护理临床缺乏足够的重视,护士忽视了检验报告在护理临床的重要意义,从而影响了护理质量的提高.本文从检验标小的质量控制和重视报告的阅读两方面,阐述护士在检验标本的质量控制和检验报告的阅读中的重要作用.

摘要： 辩证法认为一个系统是以各要素的属性为基础经由特定关系而形成的属性不可分割的整体[1]。系统所固有的属性是由各要素属性的综合性反映。临床检验在医学领域显示越来越重要的作用,特别在疾病的诊断、疗效评定等方面都起到显著的作用。基因诊断也叫DNA诊断、分子诊断,是通过从患者体内提取样本用基因检测方法来判断患者是否有基因异常或携带病原微生物[2]。基因诊断是近年来发展起来的一种诊断技术,是由生物技术发展到一定程度而产生的高新技术手段。基因诊断的出现是否取代临床检验以及两者之间的关系如何?本文将系统分析基因诊断与临床检验的关系,并就基因诊断在临床检验中的重要性做一综述。1基因诊断与临床检验的辩证关系人体细胞有23对染色体,人体的遗传性状是由位于染色体的遗传基因决定的。最近的科学研究表明,人体基因不仅决定人体表面性状,而且也决定一个人一生中是否得某些疾病,或者成为某些疾病的易感人群。于是,一种新的诊断治疗方法诞生了。它就是在临床诊断、血清诊断、生化诊断之外的基因诊断方法。基因诊断是在基因的基础上对疾病或健康作出诊断的一种技术。医学上称其为第四代的诊断技术。基因诊断是临床检验的一个部分,是临床检验发展较快的一个领域。临床检验...

摘要： 将径向基函数网络与红外光谱分析技术相结合,对正品和非正品大黄样品进行分类判别。采用小波变换对原始数据进行压缩,将原来的775个数据点压缩到4 9个变量,既保持了原来的特征谱峰又提高了网络的训练速度。对4 5种样品进行了测定和鉴别,正确率可以达到97 78%。并对影响分类结果的网络参数,目标误差和分布函数对样品分类的影响做了讨论。红外光谱法与神经网络相结合用于中草药的分类鉴定更加快速和方便。

摘要： Background Research has identified three personality subtypes in patients with eating disorders: emotionally dysregulated, constricted and high-functioning/perfectionistic. Aims To see whether the subtypes are distinguished in ways indicative of valid classification, notably in patterns of adaptive functioning, comorbidity, treatment response and therapeutic interventions. Method A random sample of experienced clinicians provided data on 145 patients with bulimic symptoms, including data on eating disorder symptoms, DSM-IV comorbidity, personality pathology, treatment response and treatment interventions. Results Patients categorised as dysregulated had the poorest functioning, most comorbidity and worst outcome, followed by patients in the constricted and high-functioning groups. The three subtypes elicited different therapeutic interventions and accounted for substantial incremental variance in outcome, holding constant the severity of eating disorder symptoms and presence of other Axis I disorders. Conclusions The data provide accumulating evidence for the validity of three personality subtypes in patients with eating disorders.

关键词： meta-analysis   partial least squares   penalized partial least squares   gradient directed path   squared error loss  

摘要： With an increasing number of publicly available microarray datasets, it becomes attractive to borrow information from other relevant studies to have more reliable and powerful analysis of a given dataset. We do not assume that subjects in the current study and other relevant studies are drawn from the same population as assumed by meta-analysis. In particular, the set of parameters in the current study may be different from that of the other studies. We consider sample classification based on gene expression profiles in this context. We propose two new methods, a weighted partial least squares (WPLS) method and a weighted penalized partial least squares (WPPLS) method, to build a classifier by a combined use of multiple datasets. The methods can weight the individual datasets depending on their relevance to the current study. A more standard approach is first to build a classifier using each of the individual datasets, then to combine the outputs of the multiple classifiers using a weighted voting. Using two quite different datasets on human heart failure, we show first that WPLS/WPPLS, by borrowing information from the other dataset, can improve the performance of PLS/PPLS built on only a single dataset. Second, WPLS/WPPLS performs better than the standard approach of combining multiple classifiers. Third, WTPLS can improve over WPLS, just as PPLS does over PLS for a single dataset.

关键词： fraud detection   wine vinegar   molasses vinegar   NIR spectroscopy   orthogonal signal correction   potential functions  

摘要： The most common fraudulent practice in the vinegar industry is the addition of alcohol of different origins to the base wine used to produce wine vinegar with the objective of reducing manufacturing costs. The mixture is then sold commercially as genuine wine vinegar, thus constituting a fraud to consumers and an unfair practice with respect to the rest of the vinegar sector. A method based on near-infrared spectroscopy has been developed to discriminate between white wine vinegar and alcohol or molasses vinegar. Orthogonal signal correction (OSC) was applied to a set of 96 vinegar NIR spectra from both original and artificial blends made in the laboratory, to remove information unrelated to a specific response. The specific response used to correct the spectra was the extent of adulteration of the vinegar samples. Both raw and corrected NIR spectra were used to develop separate classification models using the potential functions method as a class-modeling technique. The previous models were compared to evaluate the suitability of near-infrared spectroscopy as a rapid method for discrimination between vinegar origin. The transformation of vinegar NIR spectra by means of an orthogonal signal-correction method resulted in notable improvement of the specificity of the constructed classification models. The same orthogonal correction approach was also used to perform a calibration model able to detect and quantify the amount of exogenous alcohol added to the commercial product. This regression model can be used to quantify the extent of adulteration of new vinegar samples.

摘要： The objectives of this investigation were to determine the mercury content inan assortment of commercially available processed tuna samples and unprocessed fish fillet andseafood samples by applying a direct mercury analysis technique. The mercury concentrations in theprocessed tuna products ranged from 0.0329 to 0.412 mg/kg. Significant variability in the measuredmercury content was observed across all tuna packing and packaging methods, even for products fromthe same manufacturer. Products that were labelled to contain albacore tuna generally had highermercury levels than products that were labelled to contain light tuna, although overlap in mercurycontent was observed. The mercury content of fish fillets ranged from 0.00351 to 1.85 mg/kg. Thedetermined mercury concentrations for the catfish fillet, tilapia fillet, shrimp, and scallopsamples were all relatively low (<0.0400 mg/kg) compared to the other unprocessed seafood *** tuna and swordfish fillet samples had higher mercury content relative to the test samples, withconcentrations ranging from 0.0833 to 0.575 mg/kg and 0.872 to 1.85 mg/kg for tuna and swordfish,respectively..
