医科院校师生对考试现状看法的调查与分析

医科院校的考试主要是学科考试。调查显示，教师和学生对目前的学科考试模式评价均不高，存在的最主要弊端是考试方法单一，考试管理不够科学、严谨，考风不好；认为作弊的主要原因在于学生自己学习不努力、社会风气影响以及学校对教师和学生要求不够严格。因此，要搞好考试改革，提高考试质量，必须着重从改革考试方法、加强考试管理的改革与研究、整顿考风、制定科学的成绩评定方法、加强能力考核、实施教考分离等方面进行探索与实践。     

Requiring Consent vs. Waiving Consent for Medical Records Research: A Minnesota Law vs. the U.S. (HIPAA) Privacy Rule

The use of medical records in research can yield information that is difficult to obtain by other means. When such records are released to investigators in identifiable form, however, substantial privacy and confidentiality risks may be created. These risks become more common and more serious as medical records move to an electronic format. In 1996, the state of Minnesota enacted legislation with respect to consent requirements for the use of medical records in research. This legislation has been widely criticized because--it is claimed--it creates an unnecessary impediment to research. In this article, we show that these arguments rest upon misinterpretation and/or misrepresentation of the 1996 legislation. A consent requirement had actually been present in Minnesota since 1976 (though codified in a patient rights statute rather than a privacy statute). The 1996 law does not require specific consent, as often claimed, but rather only a general authorization. The campaign against the Minnesota legislation appears to have been motivated by concern with respect to the then impending federal privacy rule. The HIPAA rule, as enacted, is in fact less stringent with respect to consent than the Minnesota consent law. On the other hand, the Minnesota consent law has not been effectively applied or enforced. As we change the way we manage sensitive medical information, new efforts are needed to provide protection against the confidentiality risks in research. Patient consent is an important tool in this regard. New instrumentalities are needed to solicit and document consent.     

加强保健措施 降低孕产妇死亡率的试点研究

经调查河南省七县1988～04～1989～03孕产妇死亡率为136.1/10万,高于全国平均水平(94.7/10万)。从七县中选择了死亡率偏高的三个县(147.9/10万)为样本.进行厂降低农村孕产妇死亡率保健措施的研究。自1990年4月1日～1992年3月31日。在三县采取了以下保健措施:①加强基层妇幼卫生建设,特别是中心乡卫生院的建设,②整顿和完善三级保健网;③建全孕产妇系统管理制度,高危妊娠筛查,转化和转诊制度,④配备必要设备,建立联合小产院,实行定点接生。两年内孕产妇死亡率,由1989年的147.9/10万下降到67.7/10万,下降幅度为54.44%,最高达72.1%。此工作为实现2000年孕产妇死亡率下降一半的规划目标提供了依据。     

介入治疗并发症的发生与防治

介入治疗是融合了内科药物治疗、外科手术治疗及医学影像学的一种特殊的治疗体系 ,其疗效受到世人瞩目并成为目前发展最为迅速的学科之一。但是 ,再好的方法也会存在不足之处 ,介入治疗也不例外。随着介入治疗在各家医院的普遍应用 ,并发症的发生也会越来越多 ,迫使人们关注这个问题。所谓介入治疗并发症 ,是指因血管造影及 (或 )血管内治疗所引起、需要一定治疗、使病人的治疗复杂化或延长病人住院时间的不良反应 ,就其全身多系统而言 ,介入治疗引发并发症的原因大致可归纳为两个主要因素即介入器材操作和引入人体内的物质(包括介入治疗所…     

桡骨头切除对肘关节稳定性影响的生物力学研究

目的：探讨桡骨头粉碎性骨折不同治疗方法对肘关节稳定性的影响。方法：将10个尸体标本，分别测定在其它组织无损伤时，肘内侧副韧带切断时，肘内侧副韧带和前臂骨间膜均切断时的力－位移曲线（纵向位移）及肘外翻角。结果：肘内侧副韧带切断时的纵向位移及肘外翻角均大于其它组织无损伤时；肘内侧副韧带和前臂骨间膜均切断时的纵向位移及肘外翻角均大于其它组织无损伤时和肘内侧副韧带切断时，两两间比较均有显著性差异（P＜0．001）。结论：在其它组织无损伤时，单纯桡骨头切除是安全的；合并肘内侧副韧带损伤时，可在有效修补韧带的同时作单纯头切除，必要时行假体置换；合并肘内侧副韧带和前臂骨间膜均损伤时，最好作假体置换。     

Migration and chemical modification of silicone in women with breast prostheses

Studies using magnetic resonance spectroscopy in human volunteers to evaluate their livers in vivo and to analyze their blood in vitro suggest that there are measurable amounts of silicon compounds in the blood of some women with implants and that there is migration of silicone to other organs such as the liver.     

Integrating human factors into the medical curriculum

Background  The study of human factors is a scientific discipline that deals with the interactions between human beings and the elements of a system. This is important because shortcomings in these areas, if unchecked, can result in adverse outcomes. Research into human factors in industries where safety is paramount has provided the basis of countermeasures against human error. Adverse outcomes in medicine resulting from human error exact a high cost in both patient suffering and financial outlay.
CRM training  One of the approaches used to minimise the effect of human error is to train people in a set of knowledge, skills and attitudes that underpin the domain-specific competencies for that profession. These are referred to as non-technical skills (NTS). In aviation, such an approach has been shown to be both translatable from the training environment to the workplace and effective in reducing adverse outcomes.
Discussion  Medicine has incorporated this style of training, usually centred around simulator-based courses, but as yet in a piecemeal, episodic fashion which relies on participants volunteering to attend courses. Unlike other industries there is no systematic approach to linking the content of this teaching with the more conventional range of topics. As a consequence it is difficult to assess the impact of human factors training in medicine. This is partly because very little work has been done to date in identifying the key non-technical skills required in medicine, and the overall experience of workplace based assessment is limited. Lessons from other high reliability organisations may help to address the main challenges of developing the content, integrating it into the curriculum, reinforcing the concepts in the workplace through staff development and establishing its role in summative assessment.     

免疫性血小板减少性紫癜辨证分型与血小板表面相关抗体及T淋巴细胞亚群的关系

为探讨免疫性血小板减少性紫癜（ITP）中医辨证分型与免疫机理的关系,将ITP患者中医辨证分型结合血小板相关抗体（PAIg）及T淋巴细胞亚群进行分析。发现作为本病主要抗体的PAIgG脾肾阴亏型明显高于脾虚失统型（P<0.01）;OKT₈⁺值亦显著高于脾虚失统型（P<0.05）,OKT₄⁺/OKT₈⁺比值则明显低于脾虚失统型（P<0.05）。提示脾肾阴亏型的免疫损伤程度较脾虚失统型严重。     

Potassium and sodium ions in the nerve tissue of emotionally overstrained rabbits

Measurement of K⁺ and Na⁺ concentrations in samples of individual brain nuclei and in ganglia of the autonomic nervous system from rabbits subjected to severe emotional stress (ES) through aperiodic stimulation of ventromedial hypothalamic nuclei and electrocutaneous stimulation revealed significantly altered levels of these ions in locus ceruleus samples from animals predisposed to ES-induced cardiovascular disorders and in samples of neurons of the caudal part of the brainstem from those resistant to such disorders.
