中国大企业自主创新能力的实证测度与分析研究

 大企业是国家自主创新的重要生力军,是国家经济实力的基础和依托。本文基于灰色白化权函数定权聚类法构建了大企业自主创新能力的评价模型,并运用AHP法对测度指标进行了赋权,以33个制造业大企业为样本,对其自主创新能力进行了实证测度。结果显示：当前我国大企业自主创新能力总体状况很不乐观,其主要测度指标的表现也很不理想,与世界知名创新型企业尚有较大差距,挑战严峻,形势紧迫。     

The neutrophil-lymphocyte ratio to predict poor prognosis of critical acute myocardial infarction patients: a retrospective cohort study

IntroductionInflammation is closely related to adverse outcomes of acute myocardial infarction (AMI). This study aimed to evaluate whether neutrophil-lymphocyte ratio (NLR) can predict poor prognosis of critical AMI patients.Materials and methodsWe designed a retrospective cohort study and extracted AMI patients from the “Medical Information Mart for Intensive Care-III” database. The primary outcome was 1-year all-cause mortality. The secondary outcomes were 90-day and in-hospital all-cause mortalities, and acute kidney injury (AKI) incidence. The optimal cut-offs of NLR were picked by X-tile software according to the 1-year mortality and patient groups were created: low-NLR (< 4.8), high-NLR (4.8 - 21.1), and very high-NLR (> 21.1). Cox and modified Poisson regression models were used to evaluate the effect of NLR on outcomes in critically AMI patients.ResultsFinally, 782 critical AMI patients were enrolled in this study, and the 1-year mortality was 32% (249/782). The high- and very high-NLR groups had a higher incidence of outcomes than the low-NLR group (P < 0.05). The multivariate regression analyses found that the high- and very high-NLR groups had a higher risk of 1-year mortality (Hazard ratio (HR) = 1.59, 95% CI: 1.12 to 2.24, P = 0.009 and HR = 1.73, 95% CI: 1.09 to 2.73, P = 0.020), 90-day mortality (HR = 1.69, 95% CI: 1.13 to 2.54, P = 0.011 and HR = 1.90, 95% CI: 1.13 to 3.20, P = 0.016), in-hospital mortality (Relative risk (RR) = 1.77, 95% CI: 1.14 to 2.74, P = 0.010 and RR = 2.10, 95% CI: 1.23 to 3.58, P = 0.007), and AKI incidence (RR = 1.44, 95% CI: 1.06 to 1.95, P = 0.018 and RR = 1.34, 95% CI: 0.87 to 2.07, P = 0.180) compared with low-NLR group. NLR retained stable predictive ability in sensitivity analyses.ConclusionBaseline NLR is an independent risk factor for 1-year mortality, 90-day mortality, in-hospital mortality, and AKI incidence in AMI patients.

关于我国对俄罗斯、东欧图书馆学研究的再认识

我国的一些优秀图书情报学专家的学术成就证明，有中国特色的高水平的研究，必须广泛借鉴东西方的学术思想，否则将导致学术研究中的片面性和片断性，难以形成完整的学术体系和科学思想，要批判地借鉴国外图书情报学流派，还必须克服固守传统和追随新潮这两种倾向。恰当地对待国外近代图书情报学的传统及其成果。
