背景急性心肌梗死(AMI)是威胁全球公众健康的主要原因之一。虽然已有相应的再灌注治疗策略,但AMI相关的主要不良心脑血管事件(maCCEs)仍然是全世界人口死亡的原因之一。尤其合并糖尿病的AMI患者,因冠状动脉病变复杂,病变程度严重,尽早发现和判断该部分患者远期预后相对困难,因此寻找相对简便、易获得的实验室指标,有利于为2型糖尿病(T2DM)合并AMI患者经皮冠状动脉介入(PCI)术后maCCEs的预测提供依据。目的探讨血清C反应蛋白(CRP)/白蛋白(Alb)比值(CAR)对T2DM合并AMI患者PCI术后远期maCCEs的预测价值。方法纳入2014—2019年就诊于宁夏医科大学总医院心血管内科1683例T2DM合并AMI患者为研究对象,收集患者的一般临床资料与检查结果。对所有患者进行电话或门诊随访,以全因死亡、非致死性心肌梗死、再发不稳定型心绞痛、非致死性脑卒中、新发心力衰竭或心力衰竭加重再入院、再次血运重建作为maCCEs。根据患者随访期间是否发生maCCEs分为maCCEs组(508例)和非maCCEs组(1175例)。采用单因素及多因素Logistic回归分析探讨T2DM合并AMI患者maCCEs事件的影响因素。采用Kaplan-Meier法绘制患者的生存曲线,生存曲线的比较采用Log-rank检验。采用受试者工作特征(ROC)曲线分析CAR对T2DM合并AMI患者远期发生maCCEs的预测效能,使用净重分类改善指标(NRI)和综合判别指数(idI)评价CAR对T2DM合并AMI患者预后评估的改善效果。结果1683例患者中508例(30.18%)患者发生maCCEs。多因素Logistic回归分析显示高血压病[OR(95%CI)=1.994(1.142~3.483)]、冠状动脉植入支架长度[OR(95%CI)=1.031(1.002~1.062)]、CRP[OR(95%CI)=0.950(0.915~0.986)]、Alb[OR(95%CI)=0.933(0.880~0.989)]及CAR[OR(95%CI)=5.582(1.705~18.277)]是T2DM合并AMI患者PCI术后发生maCCEs的影响因素(PmaCCEs发生率高于CARmaCCEs的ROC曲线下面积为0.728(95%CI=0.702~0.754),最佳截断值为0.576,灵敏度为0.617,特异度为0.747。在基线模型基础上,与CRP、Alb相比,CAR能明显改善对患者发生maCCEs的预测效果(NRI=0.377,idI=0.166,C指数=0.690;PmaCCEs发生风险的有效预测指标。

Endoplasmic reticulum(ER) viscosity has emerged as a new potential biomarker for hepatic fibrosis(HF). Herein, we report the first ER-targeting viscosity-responsive near-infrared(NIR) fluorescent probe HBT-PP for investigations of HF *** twisted intramolecular charge transfer(TICT) and the excited state intramolecular proton transfer(EsIPT) are combined to endow HBT-PP with the selective response towards viscosity(～62-fold) and a super large stokes shift(～320 nm). HBT-PP mainly targets organelle ER and is able to image the drug-or alcohol-induced viscosity elevation in living cells. significantly,HBT-PP was successfully applied to visualize the gender difference in HF and the protective role of estrogen in restraining HF progression. Of note, after 10 min of stain with HBT-PP, HF lesions showed a.s.a.e-based response, indicating the potential of this probe in fast and early diagnosis of HF. These results clearly demonstrated the promising application of HBT-PP as a new tool for exploring ER viscosity-involved physiological and pathological processes.

塑造并引导个体着眼长远的激励体系是当前推进科技自强亟待破解的理论难题。现有研究多以横截面研究为主,忽视了动态视角下的时间效应。鉴于绩效报酬激励体系在激发创造力的过程中产生的两种目标导向:着眼于当下追求短期价值的表现目标导向(PGO)和着眼于学习发展寻求长期价值的精熟目标导向(MGO)。而目标的选择取决于基于时间折扣的利弊权衡“算计思维”。据此,基于时间动机理论,本文构建了一个有关绩效激励的时间动机模型,并据此设计两项研究,旨在探索考虑时间折扣影响下的短期和长期绩效报酬如何影响个体目标导向的选择进而决定其创造力。研究1的横截面研究揭示,短期内,绩效报酬强度促进个体趋近PGO远离MGO,从而负向预测创造力。研究2通过纵向的潜变量增长模型和HLM模型结果揭示,长期内,绩效报酬强度促进个体趋近MGO远离PGO,从而正向预测创造力。研究揭示了绩效报酬激励效应的时间变化轨迹和目标导向逆转现象,即随着时间的推移,绩效报酬制度引导员工逐渐从趋近PGO远离MGO,转向趋近MGO远离PGO,从而形成一个长短期“悖论”:绩效报酬制度在短期内抑制创造力而在长期内促进创造力。本文的贡献在于创建了一个时间心理计量框架,为完善以绩效报酬为核心的激励制度提供了理论和管理启示。

identification of meta-instable stress state based on experimental study of evolution of the temperature field during stick-slip instability on a 5° bending fault

引用

science China Earth sciences 2012年第6期55卷 869-881页

identification of the meta-instable stress state and study of its mechanism and evolution of relevant physical fields would be of great significance for determination of potential seismic risks and estimation of critical times. In laboratory experiments, that the specimen enters the meta-instable is marked by accelerated stress release. Could we use the experimental result to identify the earthquake in natural conditions? Because the observational data from one station can only reflect the stress state beneath this station, the key problem for identification of the meta-instability is how to recognize regional stress state through observational data from many stations. In this work, we choose the evolution of the temperature field over varied deformation stages during a stick-slip event on a 5 bending fault as an example, and attempt to find the response features of the physical quantity when the fault enters the meta-instable state. We discuss the characteristics of stages for the stress build-up, stress-time process deviating from linearity before instability, meta-instability, instability, and post-instability, respectively. The result shows that the fault instability slide is a conversion process from independent activities of each fault segment to synergism activity. The instability implies completion of the synergism. The stage deviating from linearity is the onset of stress release, and it is also the onset of the synergism. At the meta-instability stages, stress release becomes dominant, while the synergism tends to finish. Therefore, the analysis of the regional overall stress state should not start from individual stations, and instead it should begin with the evolution of the whole deformation field.

spectral principal component analysis of the Hβ region of low-redshift sDss quasars

引用

Research in Astronomy and Astrophysics 2019年第12期19卷 169-178页

作者： Bin ma Zhaohui shang Michael s.Brotherton National Astronomical Observatories Chinese Academy of Sciences.Beijing 100101China school of Astronomy and space science University of Chinese Academy of SciencesBeijing 100049China Tianjin Astrophysics Center Tianjin Normal UniversityTianjin 300387China Department of Physics and Astronomy University of WyomingLaramieWY 82071.USA

studying the relationships among quasar spectral features is essential to unveil the origins of the emission lines and the quasars’ physical processes. Principal component analysis(PCA) is a powerful tool to investigate correlations between variables. Here, we present the results of PCA on the spectra of low-redshift sDss quasars. The rest-frame wavelength range studied is 4000 – 5500 ?, involving some typical features of quasar spectra, such as Hβ, [O Ⅲ] and Fe Ⅱ emission lines. The first principal component is the anti-correlation between [O Ⅲ] and Fe Ⅱ, the well-known eigenvector one(EV1). The next six principal components also show clear(anti-)correlations between line strengths and/or velocity widths of various features, which agree well with measured spectral properties. By comparing the weights of these principal components with other quasar properties, we can identify their underlying drivers. We find that the second principal component represents spectral slope, and can quantify quasar host fraction, intrinsic slope and reddening well. The third component exhibits the velocity width variation of Hβ, and may be a proxy for orientation. In addition, we calculate the fractional-contribution spectra to investigate which components dominate the variance at individual wavelength ranges. Our results also indicate that the optical Fe Ⅱ emission may have distinct origins.
