感染性休克患者术前应用盐酸戊乙奎醚的临床疗效

观察盐酸戊乙奎醚在感染性休克患者中作为术前药应用的临床疗效.感染性休克手术患者40例,随机分为2组:实验组术前30min肌注盐酸戊乙奎醚1mg,对照组肌注东莨菪碱0.3mg.于各时间点检测血乳酸值、血气(PaO<,2>、PaCO<,2>)及胃黏膜二氧化碳分压(PgCO<,2>).结果示实验组血乳酸下降、PaO<,2>上升,PgCO<,2>-PaCO<,2>降低幅度均高于对照组(P<0.05).盐酸戊乙奎醚术前应用对感染性休克患者手术有良好的临床疗效.     

关于晚期消化道肿瘤姑息性手术治疗的思考

晚期消化道肿瘤预后差,生存期短,容易合并某种或某些严重影响脏器功能、甚至危及生命的并发症,如果手术无法彻底根治,需要尽快处理,采取姑息性手术治疗能够缓解症状、减轻痛苦、改善生活质量,甚至达到延长生命的目的。在综合治疗过程中,外科手术能够为下一步治疗提供基础,创造条件。多年以来,对于晚期消化道肿瘤的治疗,姑息性手术取得一...

高校毕业生求职行为的影响机制研究

基于计划-行为理论,考察了836名高校毕业生求职行为的预测因素及其影响机制。层次回归和结构方程分析表明,控制了城乡和政治面貌的效应后,求职自我效能、求职期望、情绪控制、人格外倾和主观支持是影响求职行为的有效因素,其中求职自我效能、情绪控制、人格外倾和主观支持分别正向预测求职行为,而求职期望则负向预测求职行为;求职意向在求职期望和求职行为、情绪控制和求职行为、主观支持和求职行为之间的中介效果均显著,在求职自我效能和求职行为以及人格外倾和求职行为之间的中介效果不显著。     

Naturalized truth and Plantinga’s evolutionary argument against naturalism

There are three major theses in Plantinga’s latest version of his evolutionary argument against naturalism. (1) Given materialism, the conditional probability of the reliability of human cognitive mechanisms produced by evolution is low; (2) the same conditional probability given reductive or non-reductive materialism is still low; (3) the most popular naturalistic theories of content and truth are not admissible for naturalism. I argue that Plantinga’s argument for (1) presupposes an anti-materialistic conception of content, and it therefore begs the question against materialism. To argue for (2), Plantinga claims that the adaptiveness of a belief is indifferent to its truth. I argue that this claim is unsupported unless it again assumes an anti-materialistic conception of content and truth. I further argue that Plantinga’s argument for (3) is not successful either, because an improved version of teleosemantics can meet his criticisms. Moreover, this version of teleosemantics implies that the truth of a belief is (probabilistically) positively related to its adaptiveness, at least for simple beliefs about physical objects in human environments. This directly challenges Plantinga’s claim that adaptiveness is indifferent to truth.     

信息的实在性与非实在性

If taking information as a philosophical concept, we will find an important philosophical problem: whether or not is it of reality? This problem also produces such a paradox: If we accept its reality, we will eliminate the difference between information and matter, and attribute information to a physical phenomena,or clear up the independent features, value and significance of information. But if we deny the reality of information, we will deny the objectivity of information or existence of any objective in...     

薪酬差距:对公司盈余管理与经营绩效的影响

本文以我国993家上市公司为样本,对高管层的薪酬差距与公司盈余管理行为和公司绩效的相关性进行了实证检验.发现上市公司高管层薪酬差距的扩大,有利于减少高管层的盈余管理串谋,从而抑制为了提高薪酬而进行的盈余管理行为.同时,薪酬差距的加大会激励高管层更加努力地工作,体现在薪酬差距大的公司总资产收益率更高.这一结果印证了锦标赛理论,而组织公平理论所主张的薪酬差距的加大对组织内部合作的破坏等负面效应目前在我国上市公司中尚未产生显著的影响.     

结直肠癌相关肿瘤标志物的最新研究进展

结直肠癌是最常见的恶性肿瘤之一。其起病隐匿、病死率较高,治疗成功的关键在于早期发现、早期诊断,结直肠癌相关肿瘤标志物曾为此做出了贡献。近年又发现了许多新的结直肠癌相关肿瘤标志物,其中有的已进入临床应用,还将有更多标志物为结直肠癌的早期诊断、疗效观察、预后判断和复发监测提供新思路和新方法。
