腮腺多形性腺瘤术式选择的思考

通过对腮腺多形性腺瘤手术切除范围确定的历史回顾,认为正是由于对腮腺多彤性腺瘤生物学行为研究的不断深入,使得腮腺多形性腺瘤手术切除范围的确定更趋于规范与科学;而生物医学模式向生物-心理-社会医学模式的转变,促进了对腮腺多形性腺瘤术式的不断改进,以最大程度减少并发症,获得更为满意的疗效.     

The Big Five personality traits,Big Two metatraits and social media: A meta-analysis

This article reported a meta-analysis of the relationships between social network site use and the Big Five (neuroticism, extraversion, openness, agreeableness, and conscientiousness) as well as the Big Two (plasticity and stability) personality meta-traits. A random effect meta-analysis model was used to calculate the meta-results of Big Five. Extraversion and openness were the strongest predictor of SNS activities (e.g. gaming, SNS interaction, etc.), while conscientiousness, neuroticism, and agreeableness only correlated with a few of the SNS activities. A meta-analytical structural equation model further demonstrated that plasticity was positively correlated with SNS activities, whereas stability was a negative predictor. Practical implications for social media industry and users were discussed.     

The effect of company recruitment web site orientation on individuals’ perceptions of organizational attractiveness

The use of company web pages to attract prospective job applicants has experienced tremendous growth in recent years. To date, very little is known about the process by which recruitment web sites influence individuals’ desire to pursue employment with an organization. This study attempts to address this issue by using an experimental design to investigate the relationships among recruitment web site orientation, individuals’ expectations concerning the use of Internet technology, web site usability, and organizational attractiveness. Survey results from 252 business students indicated that web site orientation and outcome expectancy influenced organizational attractiveness perceptions through influencing the perceived usability of the website. The implications of such results for firms interested in using recruitment web sites to attract applicants are discussed.     

抗菌药物的围手术期预防性应用

手术部位感染在所有医院感染中占第三位,大肠埃希菌、金黄色葡萄球菌、铜绿假单胞菌、表皮葡萄球菌和肠球菌属是主要病原菌,是外科临床十分关心的问题,围手术期预防使用抗菌药物能降低外科部位感染的发生率。在围手术期使用抗菌药物中,应针对不同部位的手术以及可能的病原体以及本院或本地区病原体药物的敏感性选择抗菌药物,同时应注意给要时间应在手术前30min-1h静脉使用足量抗菌药物,以保持抗菌药物的有效浓度覆盖整个手术过程。预防手术部位感染同时应关注其他综合性预防措施。     

论我国刑法妨害传染病防治罪的完善

认为妨害传染病防治罪的可罚范围有待拓宽,应将一些乙类传染病和其他突发性强、致死率高的传染病纳入本罪规制的范围;行为方式有待明确,运用刑法典与附属刑法相配合的立法模式是一种较为理想的做法;刑罚设置上有待进一步完善,增加罚金刑的适用,对后果特别严重的情形可以结果加重犯来处理。     

压力性生活事件与青少年自尊：被动性社交网站使用和人生意义感的中介作用

采用青少年生活事件量表、被动性社交网站使用量表、生命意义感量表以及自尊量表对605名青少年施测,旨在探讨压力性生活事件对自尊的效应以及被动性社交网站使用和人生意义感的中介作用。结果发现：被动性社交网站使用和拥有人生意义感在压力性生活事件与自尊之间起中介作用,压力性生活事件分别通过被动性社交网站使用、拥有人生意义感的中介作用和被动性社交网站使用与拥有人生意义感的序列中介作用对自尊产生效应。     

Sham surgery: An ethical analysis

Surgical clinical trials have seldom used a "sham" or placebo surgical procedure as a control, owing to ethical concerns. Recently, several ethical commentators have argued that sham surgery is either inherently or presumptively unethical. In this article I contend that these arguments are mistaken, and that there are no sound ethical reasons for an absolute prohibition of sham surgery in clinical trials. Reflecting on three cases of sham surgery, especially on the recently reported results of a sham-controlled trial of arthroscopic surgery for arthritis of the knee, I present an ethical analysis that focuses on the methodological rationale for use of sham surgery, risk-benefit assessment, and informed consent.     

Self-presentation and belonging on Facebook: How personality influences social media use and motivations

The present study examined the relationship between the Big Five and the use of Facebook to fulfill belonging and self-presentational needs. One hundred and eighty four undergraduates completed a survey assessing personality and Facebook behaviors and motivations. High agreeableness and neuroticism were the best predictors of belongingness-related behaviors and motivations. Extraversion was associated with more frequent use of Facebook to communicate with others. Self-presentational behaviors and motivations were best predicted by low conscientiousness and high neuroticism. Results suggest that conscientious individuals are cautious in their online self-presentation. Neuroticism, agreeableness, and extraversion were positively associated with the tendency to express one’s actual self. Neuroticism was positively associated with the expression of ideal and hidden self-aspects. The motivation to express these self-aspects mediated the relationship between neuroticism and self-disclosure.     

浅谈颈椎后纵韧带骨化症的手术治疗

摘要：颈椎后纵韧带骨化（OPLL）是一种由于后纵韧带异位骨化导致脊髓和神经根受压而产生的疾病,其病因尚未明确。手术治疗是一种有效的治疗手段,但是手术时机的选择仍充满争议。手术方法根据手术入路可分为颈前路、颈后路和前后路联合入路手术。内固定及融合方式也很多,即使同样的手术入路,也有多种不同的内固定及融合方式可供选择。不同的手术方法有不同的适应证和优缺点。本文就颈椎后纵韧带骨化症的手术治疗进行综述。     

Diagnosis and treatment of respiratory tract infections in primary health care by the nurse versus the physician: Efficacy and patient attitudes

Abstract

Five district physicians and one registered nurse were compared regarding their effectiveness in diagnosing and treating acute upper respiratory tract infections in patients (n=186) at a Swedish community health centre. Attitudes and views of the patient, or of the accompanying adult when the patient was a child, regarding the consultation itself, as well as more general aspects of health care were investigated (n=99) using a questionnaire. The questionnaire included 42 propositions of a “fuzzy” type to be judged on a 100-point truth-value scale, 18 of them concerning the consultation and 24 the more general aspects. No differences between the physicians and the nurse were found in their efficacy of diagosis and treatment. Subjects' overall attitudes were found to be positive toward both the physicians and the nurse. Results of multivariate analyses of variance performed for the consultation and general aspects of health care items separately and concerning type of persons providing health care (physician/nurse), treatment (antibiotics/no antibiotics) and patient age (child/adult), revealed overall differences in questionnaire response as regards patient age in relation to the consultation items.
