摘要： 调查显示,头颈部恶性肿瘤发病人数呈逐年上升趋势,已经成为世界上第六大常见癌症,同时也是全球第八大致死性癌症。我国头颈部恶性肿瘤的发病率>5%,其主要的治疗方式为手术和化疗。有超过70%的患者需要在治疗过程中同步进行放疗、生物治疗等联合康复治疗。在整个治疗过程中,患者一般会有较为严重的副作用,再加上自身外观的变化,极易导致患者产生相关心理疾病。

摘要： 目的分析研究糖尿病患者凝血四项检验及血脂检验的方法及临床价值。方法选择本院于2016年7月至2018年7月收治的2型糖尿病患者92例作为研究资料,均行凝血四项检验和血脂检验,为观察组,另选择同时间段本院接收的健康体检者92例作为对照组,行凝血四项检验和血脂检验检测,比较两组凝血四项指标(血浆纤维蛋白原、血浆凝血酶原时间、部分凝血活酶时间及凝血酶时间)和血脂指标(三酰甘油、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇)。结果观察组凝血四项指标血浆纤维蛋白原、血浆凝血酶原时间、部分凝血活酶时间及凝血酶时间与对照组各指标比较均差异显著,P <0.05;观察组三酰甘油,总胆固醇,高密度脂蛋白胆固醇,低密度脂蛋白胆固醇与对照组各指标比较均差异显著,P <0.05。结论针对糖尿病患者加强凝血四项检验和血脂检验对评估其凝血异常情况、血脂异常情况具有较高价值,实现相关并发症尽早发现,尽早防范,利于预后,值得推广。

摘要： 医学检验高等教育在我国发展迅速,但随着市场经济的发展和社会的进步,医学检验高等教育呈现出一些"不适应"。产学结合为医学检验人才培养提供了新思路。文章在产学结合的背景下,结合医学检验专业教育现状和存在的问题对医学检验专业产学结合的重大意义、存在的问题及发展策略进行了深入的探讨,旨在促进医学检验教育产学结合的可持续发展。

关键词： Affinity propagation   Sample entropy   EEMD   Intrinsic mode functions   Bearing fault signal classification  

摘要： For bearing fault signal classification, the performance of the affinity propagation (AP) method is limited by its way of measuring similarity. In this paper, we have proposed an improved version for the AP method, which is termed as IMFSE-AP. The key point of the proposed IMFSE-AP method is the improvement on the way of measuring signal similarity. Instead of the Euclidean distance, a novel method based on the sample entropy of IMFs (IMFSE) is proposed, which can measure signal similarities better with respect to data complexity. In the proposed similarity measurement method, signals are first decomposed into IMFs by the EEMD method. Then the distances of sample entropy vectors of IMFs are computed to evaluate similarities between signals. Numerical experiments conducted on synthetic signals and real bearing fault signals illustrate the good performance of the proposed method. (C) 2020 Elsevier Inc. All rights reserved.

关键词： EMSLIBS contest   Chemometrics   Laser-induced breakdown spectroscopy (LIBS)   Machine learning   Classification benchmark  

摘要： We present results of the classification contest organized for the EMSLIBS 2019 conference. For this publication, we chose only the five best approaches and discussed their algorithm in detail. The main focus of the contest reflected both recent and long-term challenges of Laser-Induced Breakdown Spectroscopy (LIBS) data processing. The contest was designed with a purpose to raise a challenge in handling and processing a very large dataset, containing high-dimensional elemental spectra. For the contest, 138 samples were measured using a lab-based LIBS system. In total, the data set consisted of 70,000 spectra, separated into 12 classes according to their elemental composition. Due to its extensivity and complexity, the data set is unique within the LIBS community. The central idea was to simulate the so-called "out-of-sample" classification (i.e. according to similar elemental composition), implying various real-world applications. Even more, it reflects the current level of expertise in the LIBS community and the capability of the LIBS method itself.

关键词： Autism spectrum disorder   Autism-related traits   Military   Suicide risk   Unit cohesion  

摘要： Background: Suicide rates are elevated among United States (U.S.) military service members. Research has found that service members with autism spectrum disorder-related (ASD-related) traits are at increased risk for suicide. Complementary lines of inquiry have suggested that unit cohesion is a protective factor against developing suicidal ideation in military service members. However, given the social difficulties inherent in ASD, it is unclear whether unit cohesion might protect against suicide risk in this population. Method: Our sample consisted of 285 active duty U.S. military service members recruited online. We examined the interaction between ASD-related traits (as measured by the Autism Spectrum Quotient [AO] ), unit cohesion, and suicide risk (as measured by the Suicidal Behaviors Questionnaire-Revised [SBQ-R]). We also conducted exploratory analyses to examine whether unit cohesion attenuates the association between ASD-related traits and suicidal intent. Results: Elevated ASD-related traits were independently associated with higher levels of global suicide risk;however, unit cohesion was not independently associated with suicide risk. Unit cohesion did not significantly interact with ASD-related traits to predict suicide risk. Finally, we found that elevated ASD-related traits and unit cohesion have an independent effect on current suicidal intent. Discussion: Our findings suggest that unit cohesion might not buffer the effect of ASD-related traits on suicide risk. However, our results do show that greater unit cohesion may be independently associated with decreased suicidal intent. This study is limited by a cross-sectional design and use of self-report measures.

关键词： 糖尿病患者   血脂检验   继发性并发症  

摘要： 目的:研究血脂检验在糖尿病患者中的应用效果及对继发性并发症发生的作用。方法:2018年4月-2019年5月收治糖尿病患者40例作为试验组,同时选取同期体检的健康志愿者40例作为对照组。比较两组高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、甘油三酯(TG)、总胆固醇(TC)及载脂蛋白(ApoA1、ApoB)水平。结果:试验组HDL-C、ApoA1水平显著低于对照组,LDL-C、TG、TC、ApoB水平显著高于对照组,差异均有统计学意义(P<0.05)。结论:对糖尿病患者给予血脂检验能够对其继发性并发症的发生进行有效判断,有利于制定相应的治疗预防措施,具有良好的检验价值。

关键词： 企业家精神   创新精神   冒险精神   企业成长  

摘要： 本文对企业家精神、企业成长及二者相互关系的研究文献进行了回顾,归纳提出了3个基本假设和16个从属假设。借助剔除了缺失项后的2321个中国上市公司面板数据,利用结构方程模型分析工具,透过研究所构建的模型,对本文提出的各个研究假设进行了检验。本文基于样本公司数据,测算了企业家精神水平,并对不同类型企业家精神水平进行了简单分析。研究检验了样本公司数据与所构建模型的拟合性,发现样本公司数据能够与模型较好拟合。隐变量模型检验发现,关于冒险精神与创新精神之间存在互为因果关系的假设,以及冒险精神对企业成长具有显著负向影响的假设,得到了检验的严格的支持;但创新精神与企业成长之间存在显著正向影响的假设没能得到严格支持。在观察变量之间关系方面,只有4个从属假设得到了检验的严格支持。此外,研究发现,子样本与总体样本之间的检验结果存在显著差异,子样本之间在模型匹配性与输出结果上都存在显著差异;只有民营企业与制造业子样本能够与模型很好拟合,并输出有效检验结果。
