关键词： 新生儿   溶血   生化检验  

摘要： 目的分析新生儿溶血样本对生化检验结果的作用及优化措施。方法选取我院2012年5月-2014年8月期间实施生化检验的68例新生儿作为研究对象,所有患儿均常规采集血液标本,每例患儿采集两管,一管作为溶血标本,另一管作为未溶血标本,检测两组标准的谷丙转氨酶、总胆红素、直接胆红素、尿酸、谷氨酰转肽酶、谷草转氨酶水平并进行对比。结果研究结果显示,两组新生儿谷丙转氨酶、总胆红素、直接胆红素、尿酸、谷氨酰转肽酶、谷草转氨酶水平比较差异有统计学意义(P<0.05)。结论新生儿溶血样本会对生化检验结果造成很大的影响,尤其是谷丙转氨酶、总胆红素、直接胆红素、尿酸、谷氨酰转肽酶、谷草转氨酶水平,需引起临床人员重视,在开展溶血检验过程中积极通过合理选择采血点、采血方式等优化措施,避免或减少溶血发生。

摘要： 目的分析研究在贫血的鉴别诊断中血液检验所起到的作用。方法选取杭州市拱墅区米市巷街道社区卫生服务中心2012年8月-2014年4月经检验的贫血患者60例,作为观察组,其中30例为溶血性贫血患者,作为观察组1,另30例为缺铁性贫血患者,作为观察组2,再选取30例正常人作为对照组,均对其血细胞进行检测,观察3组患者血液中的RBC、MCV、Hb、MCH、RDW指标的差异,以及观察组中两组的灵敏度,特异性和符合率的差异。结果观察组1中RBC指标低于对照组,观察组2中Hb指标明显低于观察组1和对照组,对照组中MCH明显高于观察组1和观察组2,组间对比差异具有统计学意义(P<0.05)。观察组1与观察组2灵敏度、特异度和符合率的差异不具有统计学意义(P>0.05)。结论血液检验在贫血类型的鉴别诊断中,发挥重要的作用,具有一定的临床价值。

摘要： Detection and identification of natural or intentional contamination have become very critical in drinking water. Feature selection plays an important role in both detection and classification and has become an active research area in pattern recognition, statistics and data mining communities. As the dimensionality enlarges, the feature set increases in size. Feature selection is a pre-processing technique commonly used in all high dimensional data. The focus of feature selection is to select the subset of features (variables) from the input, which can efficiently describe the input data, by identifying irrelevant data or noise to produce high- quality results of prediction. A feature is one of the measurable properties of the process being observed. In this research, an attempt has been made to investigate the pre-processing framework for feature selection in drinking water dataset, using Back Propagation Neural Network (BPNN) and Support Vector Machine (SVM). The main purpose of this work is to select a subset of features or list of attributes or variables which help to describe data for constructing models. Selection of features and training of the model are performed simultaneously in this work. The wrapper based method is used to select the subset of features, and the model is trained with SVM classifier. SVM and BPNN classifiers are used to train drinking water dataset for two different seasons, and comparisons are made between two classifiers, to conclude that the performance of SVM is better when compared to BPNN.

摘要： The research examined the role played by bank inspection in the viability of commercial banks ( a case study of UBA). It adopted a questionnaire-based method of evaluation based on five point likert scale and tested the efficacy of the Hypothesis using the chi-square method. The study revealed that the Bank inspection functions have not been effective in creating stability in the commercial banking system. Bank inspection functions have not been effective in improving Corporate Governance issues in commercial banking system. Bank inspection have not stemmed the incidence of widespread bad loan portfolio in the commercial banking system. Effective inspection would boost the volume and the value of transactions witnessed in commercial banks.

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.

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。
