目的探讨各级高血压病与颈动脉硬化之间的关系。方法对558例高血压病患者的颈动脉内膜中层厚度（IMT）、斑块发生率进行检查分析,并与209例健康成人对照。结果各级高血压患者颈动脉IMT与对照组相比均有明显增加;各级高血压病患者颈动脉IMT之间进行比较亦显示出显著性差异;颈动脉IMT随高血压分级增加而逐渐增厚。结论血压增高与高血压病患者颈动脉变化密切相关,颈动脉超声检测对于防治高血压及其并发症具有重要意义。     

冠心病患者血浆同型半胱氨酸变化及叶酸的干预治疗

目的 了解血浆同型半胱氨酸(Homocysteine，Hcy)、叶酸和维生素(Vit)B12水平与冠心病的关系；观察叶酸干预治疗高Hcy血症的疗效．方法 经冠脉造影确诊的冠心病患者97例、亚冠心病患者58例及完全正常3l例，用高效液相色谱法测血浆Hcy水平，用放免法测血浆叶酸和VitB12浓度．其中高Hcy血症病人每天服用叶酸5mg，观察4周和8周后血浆Hcy水平变化．结果 冠心病和亚冠心病患者血浆Hcy水平明显高于正常人，叶酸和VitB12水平则明显下降；冠心病患者冠脉病变支数越多，血浆Hcy升高和叶酸、VitB12下降越明显；叶酸治疗高Hcy血症患者4周和8周，分别使血浆Hcy水平下降12．5％和38．5％．结论 冠心病和亚冠心病患者血浆Hcy水平明显升高，高Hcy血症是冠心病的危险因素之一．血浆Hcy水平变化与冠脉病变程度正相关．叶酸干预治疗可使高Hcy血症患者血浆Hcy浓度明显降低．

探析深度学习表征的一种新方法:社会认知网络特征(SENS)

近年来,深度学习在教育领域越来越受到重视,它被划分为三大维度:认知领域、人际领域和自我领域。已有的基于问卷、测试题和访谈等方式进行的学习效果分析,难以满足人们对于深度学习中的动态、过程和综合的分析需求。作为一种新的研究方法,社会认知网络特征(SENS)结合了社会网络分析(SNA)和认知网络分析(ENA)两种分析方法,能够很好地对深度学习的三个领域进行分析。通过对原有的SENS方法进行改进,提出了适合深度学习SENS方法的一般步骤,并对每个步骤进行详细的介绍;通过以两个典型案例展示如何利用SENS来促进深度学习,并将深度学习和在线协作数据分析相结合;提出了应用SENS的一些经验与建议,以期为今后研究深度学习提供新的思路和方法。

Spinoza,Deep Ecology and Education Informed by a (Post)human Sensibility

Abstract

This article explores the influence of Spinozism on the deep ecology movement (DEM) and on new materialism. It questions the stance of supporters of the DEM because their ecosophies unwittingly anthropomorphise the more-than-human-world. It suggests that instead of humanising the ‘natural’ world, morality should be naturalised, that is, that the object of human expression of ethics should be the more-than-human world. Moreover, the article discusses Deleuze’s Spinozism that informs new materialism and argues that stripping the human of its ontological privilege does not deprive the human animal from its ethico-normative distinctiveness. Implications of the discussion for an education aimed at cultivating (post)human sensibilities are explored.     

Deep lingual arterial chemoembolization of tongue carcinoma with microcapsuled anticancer drug

Objective: Microcapsule chemoembolism is a promising treatment of tumors. We describe a deep lingual arterial embolization of tongue carcinoma with microcapsuled carboplatinum. Methods: Lingual artery cast specimens from cadavers were microscopically examined, and 78 patients with tongue cancer were recruited and treated with the deep lingual arterial embolization therapy. Results: Microcapsule embolism occurred approximately at the fifth or sixth level of the deep lingual artery branches. The five-year survival rate was 88.5% (69 out of 78), and the ten-year survival rate 52.6% (41 out of 78). Conclusion: The deep lingual arterial embolization of tongue carcinoma with microcapsuled carboplatinum is an effective therapy to treat carcinoma in mid-margin or mid-body of the tongue.     

Slow thinking and deep learning: Tversky and Kahneman's taxi cabs

This article is based on classroom application of a problem story constructed by Amos Tversky in the 1970s. His intention was to evaluate human beings' intuitions about statistical inference. The problem was revisited by his colleague, the Nobel Prize winner Daniel Kahneman. The aim of this article is to show how popular science textbooks can serve as a source for rich classroom activity, with a little care in the implementation by teachers. Kahneman describes the problem as ‘standard’ and answers using a fixed point number. I describe how I have encouraged my students to challenge the certainty of this assertion by identifying ambiguities that are left unexplained in the story. This way, I claim to stimulate individuals to indeed move towards Thinking, Fast and Slow, the title of Kahneman's book.     

马里亚纳海沟Challenger Deep的岩石圈流变结构与动力学分析

马里亚纳海沟是西太平洋板块边缘沟-弧-盆体系构造演化的关键地区,其南端的Challenger Deep不仅是地球表面最深点,也是马里亚纳海沟、马里亚纳岛弧、马里亚纳海槽、西马里亚纳洋脊和帕里西维拉海盆的构造汇聚点。开展岩石流变结构与动力学过程研究对于认识Challenger Deep的形成演化具有重要的科学意义。利用综合地球物理资料,通过对重、磁数据的计算分析,研究马里亚纳沟-弧-槽-盆系统的等效黏滞系数和岩石圈强度等流变学特征。利用地震资料,勾绘海沟之下贝尼奥夫带随深度变化的特征以及陡变形态。计算结果表明：对应马里亚纳海沟-岛弧-海槽系统,自由空气重力异常向东凸出,形成弧型异常区;区内异常表现为串珠状线性特征,异常值中间高,两侧低。不同深度岩石圈累积强度比值表明,海沟南北两侧地壳上硬下软,海沟中部地壳上软下硬。在给定应变速率条件下计算的等效黏滞系数东高西低,说明西侧构造体地壳比东侧构造体地壳更容易变形。Challenger Deep岩石圈强度较大,等效黏滞系数较高,具有上硬下软的流变学特征,为板块俯冲在该区的弯曲、撕裂与快速翻转提供了重要条件。地震与重力剖面分析表明,Challenger Deep处的岩石圈累积应力强度和有效粘滞系数条件,可以使马里亚纳海沟俯冲带在重力作用下弯曲、开裂,或部分向南翻转、变陡。
