城市社区医疗预防保健人员知识与技能的需求调查

通过对405名城市基层医疗预防保健人员的知识和技能的需求调查看出,面对医学模式的转变,社区居民医疗预防保健需求的不断增长,他们现有的知识和技能已极不适应。2/3以上的人员认为以往所学的知识不够用,较普遍地要求增加预防医学、临床医学等课程的学习,提高疾病诊断、群众工作、组织交往、科研的能力。调查为基层在职医学教育提供了参考依据。

重组人干扰素α-2b鼻腔喷雾剂预防治疗恒河猴感染SARS-CoV的试验研究

目的评价重组人干扰素α-2b鼻腔喷雾剂对恒河猴感染SARS-CoV的预防治疗作用。方法采用鼻腔喷雾法(剂量为60万单位/鼻孔)研究了重组人干扰素α-2b鼻腔喷雾剂对感染SARS-CoV的恒河猴预防治疗效果。结果试验组(5只)和对照组(5只)相同时间检测的咽拭子等标本中,Real-time PCR检测和病毒分离均未检出病毒。攻毒后病毒导致机体产生的中和抗体和IgG抗体的反应也较对照组弱。血液学指标检测结果表明试验组动物攻毒后各项指标较试验前比较没有显著性改变;病理结果显示试验组2只恒河猴肺组织形态基本正常,其余3只猴有肺间质性炎,表现肺间隔增厚、单核样细胞为主的炎细胞浸润,其中1只增厚的肺间隔有局灶相互融合,这3只猴肺部病变与对照组的病变表现相似,且病变累及范围较对照组小;其他各受检脏器均未见明显异常。结论重组人干扰素α-2b鼻腔喷雾剂可以有效阻断或减弱SARS-CoV对恒河猴的感染。     

Alcohol and obesity: A new look at high blood pressure and stroke

Summary An investigation of the staff of a car assembly plant (3,351 persons) revealed a similarity between the change in relative body weight and diastolic blood pressure with age. There is a good temporal correlation between the course of alcohol consumption during life and the change of the relative body weight. German women had significantly less blood pressure for the same relative body weight than German men, and foreign employees had lower blood pressure than Germans In both cases the main cause is the difference in alcohol consumption. Besides obesity and hereditary factors, alcohol is the main cause of essential hypertension today. Epidemiological and experimental data indicate that there are two ways from alcohol to high blood pressure, a more direct one and an indirect one via obesity. Alcohol causes obesity via a change in metabolism (hyperinsulinism) rather than by higher caloric intake. In both ways alcohol is an important cause of stroke. To reduce body weight and blood pressure, a reduction of alcohol consumption should be recommended in addition to reduced caloric intake and increased physical activity as means of preventive neurology.     

Minimal interventions for weight control: a cost-effective alternative

Two studies were conducted to evaluate simpler, less intensive interventions for weight control which presumably would be more cost-effective and efficient than a "full-length" behavioral treatment program. In Study 1, participants in a minimal intervention (MI1) program who attended no regularly scheduled meetings and initially only received three simple verbal instructions about how to lose weight, lost an average of 11.1 lb. by 7-month follow-up. Subjects in three variations of a shortened, less intensive, 6-week behavioral weight loss program lost 7.8, 6.5 and 6.3 lb. but did not significantly differ from MI1 subjects in the amount of weight lost. In Study 2, MI2 subjects lost 5.5 lb. compared to subjects in two variations of a full-length program who lost 8.1 and 11.1 lb. by 6-month follow-up. Again, none of the groups significantly differed from each other in the amount lost. It was concluded that a minimal intervention program seems to produce weight loss and to be a cost-effective and efficient method for some subjects. The difference between the two minimal intervention programs may be related to the payment of a monetary deposit; a model for future research was presented to investigate simpler, less intensive interventions in combination with more complex ones in a "stepped-care" fashion.     

PBL教学模式对预防医学生课程教学效果的系统评价

目的 系统评价PBL教学模式对预防医学生课程教学效果的影响。方法 检索PubMed、CNKI、WanFang Data、CBM和VIP数据库,搜集PBL应用于预防医学生教学的RCT研究,采用R软件（3.6.2版本）进行Meta分析。结果 共纳入23篇文献,包括2 108例研究对象。Meta分析结果显示,PBL组预防医学生的理论成绩［ SMD =1.13,95% CI (0.65,1.60)］、实践操作成绩 ［ SMD =1.27,95% CI (0.91,1.63)］、教学满意度［ RR =1.33,95% CI (1.17,1.52)］、学习兴趣［ RR =1.61,95% CI (1.37,1.89)］、自主学习能力 ［ RR =1.63, 95% CI (1.39,1.92)］、团队协作能力［ RR =2.11,95% CI (1.54,2.89)］、解决问题能力［ RR =1.58,95% CI (1.36,1.83)］均显著优于LBL组。亚组分析结果显示PBL联合教学组预防医学生的理论成绩［ SMD =1.27,95% CI (0.46,2.09)］、实践操作成绩［ SMD =1.39,95% CI (0.82,1.96)］、团队协作能力［ RR =2.27,95% CI (1.41,3.64)］均优于单独使用PBL组,PBL在毒理学课程中对提高预防医学生的理论成绩［ SMD =1.44,95% CI (1.10,1.79)］和实践操作成绩［ SMD =1.16,95% CI (0.74,1.59)］效果均较为显著。结论 PBL对预防医学生的教学效果具有显著影响;PBL联合教学比单独使用PBL的教学效果更显著;未来需纳入更多严谨的试验设计来验证其应用效果。

Removing risk stratification in food allergy prevention guidelines

There is now level one evidence based on randomized controlled trials that early ingestion of allergenic solids in infancy has a preventive effect against food allergy development. As a result, guidelines now recommend early ingestion of allergenic solids as a means of food allergy prevention. However, guidelines in Canada currently focus this intervention specifically on infants at risk, defined currently as an infant who has a history of atopy such as eczema or food allergy, or who has an immediate family history of atopy. However, this definition fails to account for studies supporting early ingestion as a preventive measure within the broader population. Not all of these risk factors (such as immediate family history of atopy) are consistently supported by the literature to date. Finally, a more universal approach to food allergy prevention simplifies the message, decreases stigmatization, and reduces medicalization of infant feeding. It also has the potential to reduce reticence to feed in infancy. The goal of this commentary is to argue that food allergy prevention guidelines should focus their interventions on the broader population and not just those defined as at higher risk.     

强化预防战略意识 深化医学教育改革

在临床医学专业的学生中进行预防医学实践,是医学教育史上的一项改革.我们打破了传统的医学教育模式,建立了以服务为前提的服务教学科研相结合的农村教学基地,改变了过去那种“只治不防”的被动局面.这种改革符合我国“预防为主”的战略思想,是实现世界卫生组织提出的“2000年人人享有卫生保健”这一目标的有力措施.
