开展卫勤指挥员任职培训的教学实践和体会

近几年来,第二军医大学卫生勤务学系承担了大量卫勤指挥员的任职培训任务.通过几年的理论研究和实践摸索,在教学的组织、管理、实施、保障等方面积累了一些经验,获得了一些具体的体会.我们认为要做好卫勤指挥员的任职培训教学必须明确培训目标,科学制定教学方案,精心安排教学内容,做好施训教员的培训,并在教学中注重合理运用教学方法,特别是要做好下部队调研,切实提高教学实效.

腰穿术后平卧方法的临床观察

目的 通过腰穿术后病人平卧方法舒适度的临床观察比较,从而探讨选择术后最佳的平卧方法.方法 观察并记录2001-02～2006-09的1070例门诊腰穿术后病人,2种平卧方法(即去枕仰卧位和低枕卧位)的舒适度.结果 随机分2组2种平卧方法临床观察,低枕卧位明显优于去枕仰卧位.结论 腰穿术后低枕卧位方法的选择对病人术后的尽快恢复,有较好的帮助.     

扩张程度和皮肤血运关系的实验研究

目的研究扩张皮肤血运和扩张程度的关系。方法以扩张容量和扩张皮肤面积作为扩张程度的指标，观察猪皮肤在不同程度超量扩张下的皮肤激光多普勒血流值（LDF）和血管造影。结果超量扩张下LDF呈下降的趋势，而血管密度却是增加的，主要以小静脉和微小静脉的增生扩张为主。结论超量扩张下虽然皮肤血管密度增加，但皮肤血运却逐渐下降。本文浅略解释了这一特殊现象的机制。     

Continuing professional development for radiographers

Purpose: The purposes of this survey were to identify the current participation in Continuing Professional Development (CPD) of radiographers in the South and West Regional Health Authority (SWRHA), and to invite them to comment on issues related to CPD activities.Methods: A questionnaire was sent to 1686 diagnostic and therapy radiographers in the SWRHA. This was designed to gain a profile of those radiographers currently practising and their participation in, and comments on, CPD activities.Results: A response rate of 51% was achieved, although only 634 questionnaires were used for the final analysis. The population of radiographers who responded were predominantly diagnostic, in the age range 26–45 years, female and employed on a full-time basis. Most respondents did not hold any post-registration qualifications, and only 149 respondents were involved in formal studies. Most respondents were involved in statutory CPD activities such as resuscitation and manual lifting, and fewer, although a majority, were involved in activities associated with changing roles and developing new competencies. Other CPD activities which respondents considered as benefiting their professional role were wide ranging. Most of the issues raised concerning CPD related to provision, support and funding.Conclusions: The challenge for the future is to develop a coherent, progressive and affordable scheme of CPD to meet the needs of individual radiographers, the health services, the patient and the profession.     

美托洛尔对急性心肌梗死早期QT离散度的影响

目的 :探讨急性心肌梗死早期应用美托洛尔对QT离散度 (QTd)的影响。方法 :选择符合条件的 14 2例急性心肌梗死 (AMI)患者 ,男 95例 ,女 47例 ,平均年龄 5 7± 12 3岁 ,随机分为治疗组 78例 ,对照组 64例 ,两组病例性别、年龄等基本情况相似。在AMI常规治疗的基础上 ,治疗组给予美托洛尔 6 2 5～ 5 0mg口服 ,2次 /d ;对照组仅常规治疗。治疗前及治疗 1周后同步记录体表常规 12导联心电图 ,每一导联连续测量 3个Q -T间期 ,取其均值。最大QT间期 (QTmax)与最小QT间期 (QTmin)之差为QTd。结果 :治疗组在常规治疗基础上早期给予美托洛尔后 ,QTd、QTcd显著缩小 (P <0 0 1) ,QTmax无明显改变 (P >0 0 5 ) ,QTmin显著延长 (P <0 0 5 ) ,心率显著减慢 (P <0 0 1)。而对照组QTd、QTcd、QTmax、QTmin、HR均无明显变化 (P >0 0 5 )。结论 :AMI早期应用 β1 受体阻滞剂美托洛尔治疗 ,可显著延长正常心肌的复极过程 ,从而防治早期恶性心律失常 ,降低猝死率。     

The Development and Teaching of the Ethical Principles and Guidelines for Family Scientists*

This article describes the development of the Ethical Principles and Guidelines for Family Scientists that the National Council on Family Relations Board of Directors unanimously approved. Furthermore, it discusses the importance of ethics education for family professionals and provides suggestions for educators. Finally, the ethical principles and guidelines are delineated. We argue that the development of a scholarship on ethics education is important for current and future family scientists.

PBL-CBL整合教学在内分泌科轮转临床医学专业学位研究生培养中的应用

目的 探讨以问题为基础的学习（problem-based learning,PBL）-以案例为基础的学习（case-based learning,CBL） 整合教学在内分泌科轮转临床医学专业学位研究生培养的效果。方法 将80名在内分泌科轮转的临床医学专业学位研究生随机分为试验组（采用PBL-CBL整合教学）和对照组（采用传统教学）,每组40人,轮转期为3个月。记录两组学生入科和出科时专业考试成绩,并通过问卷调查分析自信心、学习主动性和人际交往能力。采用SPSS 20.0进行t检验、卡方检验。结果 两组学生基线情况一致,经过3个月的转轮期后,与入科前相比,试验组学生的出科考试成绩、自信心、学习主动性和人际交往能力明显提升,差异均有统计学意义（P<0.001）。结论 PBL-CBL整合教学效果优于传统教学,有助于提高临床医学专业学位研究生在内分泌轮转的学习能力和成绩,值得推广。
