结直肠癌化疗患者营养状况及营养治疗研究进展

结直肠癌是常见的消化道肿瘤，其营养不良发生率高且严重。化疗是结直肠癌常见治疗方式之一，并与营养不良独立相关，化疗后患营养不良风险增大且营养不良进一步加重。同时，营养不良可导致患者化疗疗效差及预后不良，并增加化疗相关不良反应、影响患者生活质量及降低生存率等。营养治疗能够有效改善患者营养状况，在肿瘤综合治疗中有重要作用，且多学科团队合作是有效的营养干预模式。目前营养治疗主要包括营养咨询、口服营养补充剂、肠内营养和肠外营养等，相关指南和研究表明在营养治疗时应首选口服营养补充剂及肠内营养，仅在采用以上治疗后仍存在营养不足或无法进行肠内营养时行肠外营养。本文主要对结直肠癌患者营养状况与化疗之间关系、营养治疗的最新研究进展及相关指南进行综述，以期引起临床上对结直肠癌化疗患者营养治疗方面重视并提供参考。     

营养支持在重症心脏瓣膜病外科的临床应用

目的 探讨营养支持在重症心脏瓣膜病外科治疗中的作用。方法2000年5月-2005年5月对182例重症心脏瓣膜病行瓣膜置换术，围术期采用营养支持疗法。其中单瓣病变74例，二尖瓣合并主动脉瓣病变108例。135例行三尖瓣成形术，37例行左房折叠术。结果 182例住院死亡5例，死亡率2.7%，术后并发低心排15例，死亡1例，随访151例，结论 科学的应用营养支持方案，可以明显地提高重症心脏瓣膜病外科手术成功率。     

The Influence of Academic Support on Latino Adolescents’ Academic Motivation

Abstract: The current study examined the extent to which mothers, fathers, teachers, and teenage friends influenced Latino adolescents’ academic motivation. Using path analysis, separate models were tested for 154 Latino boys and 156 Latina girls. Findings indicated that mothers’ and teachers’ academic support were positively related to adolescent girls’ academic motivation, and fathers’ and teachers’ academic support were positively related to adolescent boys’ academic motivation. The salience of teachers’ support, possible reasons for gender differences, and implications for future research are discussed.     

管理人员职业紧张常模及转换表研制

目的中高层管理人员、一般管理人员职业紧张常模、应用表、分级标准研究。方法采用职业紧张量表(OSI-R),对中高层管理人员263例、一般管理人员569例,共计832例常模样本进行研究。结果首先,采用OSI-R量表分别研制了中高层管理人员、一般管理人员职业紧张常模;其次,在常模的基础上,分别研制了常模样本粗分转换为T分表。职业紧张程度分级职业任务和紧张反应问卷中,T分≥70分者,为高度职业紧张、紧张反应;T分在60分至69分范围内者,为中度职业紧张、紧张反应;T分在40分至59分范围内者,为适度职业紧张和紧张反应;处于正常范围。T分低于40分者,为相对缺乏职业紧张和紧张反应。在应对资源问卷中,T分低于30分者,表明高度缺乏应对资源;T分在30分至39分范围内者,表明中度缺乏应对资源;T分在40分至59分范围之间者,具有适度的应对资源,属于正常范围;T分≥60分者,表明有很强的应对资源。结论将职业紧张的模式结合中高层管理人员、一般管理人员职业紧张常模及应用表,分别针对不同个体主要紧张源、紧张反应、应对资源,采取有针对性的干预(组织、个体)措施,以降低中高层管理人员、一般管理人员职业紧张程度,保护和促进工作能力是职业卫生领域面临的重要任务之一。     

Making clinical decisions for dental care: concepts to consider

Clinical decisions are often made with incomplete information, yet patient care decisions are made every day. Patients vary clinically, uncertainty exists in diagnostic and prognostic information, and many preventive and treatment alternatives have not been formally assessed for their effectiveness. Because scientific information will never answer all clinical questions, clinical decisions are partially based on probabilistic information.
This paper describes how to apply clinical decision making to diagnosing and managing dental caries and periodontal diseases. By using explicit information to quantify probabilities and outcomes, clinical decision making analyzes decisions made under uncertain conditions and the uncertain impact of clinical information.
Clinical decision making incorporates concepts for preventing, diagnosing and treating dental caries and periodontal diseases: risk assessment, evidence-based dentistry, and multiple oral health outcomes. This information can serve as a tool for clinicians to augment clinical judgment and expertise.     

社会支持对企业员工工作倦怠的影响

目的了解企业员工的工作倦怠状况，探讨社会支持对企业员工工作倦怠的影响并提出组织管理建议。方法以社会支持问卷和MBI-GS问卷对588名企业员工进行调查。结果企业员工的工作倦怠程度并不高，但仍存在．且以情绪耗竭的程度教高；社会支持与工作倦怠及共各构面部分呈显着负相关，社会支持对工作倦怠及其各构面具有显着的预测力，结论社会支持对企业员工工作倦怠有一定的影响．应引起管理者的重视。     

Cancer support groups – are they effective?

Cancer causes significatlt emotional distress to a considerable majority of patients. Many of these patients typically receive little formal psychological intervention. Support groups, however, have provided one forum from which patients can attempt to gain help and can use to overcome some psychological trauma that accompanies the cancer hagnosis, subsequent treatment and relapse. This article reviews past studies of professionally run cancer support groups as opposed to psychological intervention groups. These studies are considered in light of the proposed benefits and the methodological limitations frequently inherent in such studies.     

多模式临床支持系统的研究进展

目的探讨多模式临床支持系统的研究进展。方法通过了解国际多模式临床支持系统发展和运作情况,并与传统的临床支持系统进行对比,探讨多模式临床支持系统的国际研究进展情况。结果在多模式临床支持系统概念、目的及特点认识的基础上,了解了多模式临床支持系统的国际进展情况。结论临床支持系统模式的发展和演变,为多学科协作诊治模式提供了新的临床辅助,加强了循证医学的临床实践和相应的提升体系,但临床支持系统项目在目前我国医院的应用还需要进一步探讨和研究。
