急诊工作的"预防为主"以及"濒危意识"和"濒危状态"

危险性急症的发现、诊断和抢救，是全部急诊工作中最重要、也是最困难的工作。如果一个急诊医生已经具有了很强的“危机意识”、掌握了急诊工作的全部思维特点，因此具备了很强的“三快”能力，从而能够迅速地发现并且抢救危险性急症，那么是否可以认为他是一个优秀的急诊医生呢？     

论"热痹"与"痹热"

中医学对痹病的认识有2000多年历史,无数医家对其病因、病机治疗等方面进行了广泛而深入的探讨,并积累了许多宝贵的经验.     

"健康"从"心"开始

据2006年世界心脏联盟统计,在全世界范围内,每死亡3人,就有1人的死因是心血管病症。中国40岁以上的人群中,62%的人不同程度地存在心血管病或危险因素,80%的人尚未充分了解如何保持心脏健康。为此,本刊在世界心脏日来临之际,推出特别策划:     

浅谈"久病入络"

清代医家叶天士提出的"久病入络"的学术思想,发前人未发之旨,并创立治络之法,在临证中"治经千百,历有明验",至今仍对临床疑难杂症的治疗发挥着指导作用.兹仅对其在理论上作一简要阐述.     

"死亡率"与"病死率"的区别

某疾病死亡率(cause—specific death rate)：因某种疾病所致的死亡率，是死因分析的重要指标，它反映各病伤死亡对人们生命的危害程度。其算式为：     

"游泳"与"抚触"对新生儿健康的临床研究

目的探讨"游泳"与"抚触"活动对新生儿健康的影响.方法将95例正常新生儿按分娩顺序分为观察组("游泳"与"抚触")48例;对照组(单纯沐浴)47例.统计对比2组新生儿的出生体重、出生后第10天体重、出生后第42天体重、生理性黄疸开始消退时间、生理性黄疸完全消退时间.结果观察组新生儿第10天平均体重3 500g,第42天平均体重4 560 g,对照组新生儿第10天平均体重3 300 g,第42天平均体重4 080 g.观察组生理性黄疸开始消退时间(5.5±1.3)天,生理性黄疸完全消退时间(11.87±1.2)天.对照组生理性黄疸开始消退时间(6.3±1.1)天,生理性黄疸完全消退时间(13.67±1.7)天.结论新生儿"游泳"与"抚触"有助于新生儿身心的健康发育.     

"医声"刊首语

医院是救死扶伤的圣洁之地,医护人员长期以来被喻为白衣天使.在广大就诊者的心目中,医生、护士是保证他们生命的最后一道屏障.然而,近几年来,医患关系日趋紧张,各种媒体有关医生拿回扣、开大处方、对病人不负责任的报道不绝于耳,医护人员的良好社会形象一落千丈.医护从业者面临着政府的期盼、行业的要求、患者的不解等多方面的精神压力.     

如何解读"空腹"

实验诊断学是临床医学生必修课程之一,名词解释即定义在实验诊断学课程中是最基本的学习内容,正确理解和掌握定义的本质和外延至关重要,不仅影响现阶段的学习,更直接影响其后续课程的学习,其教学效果甚至可能涉及学生毕业以后的职业生涯,因此对医药院校从事实验诊断学教学的教师提出了更高的要求.     

Simian Blood Groups Two "New" Blood Factors of Gibbon Blood, Ag and Bg

By isoimmunization of gibbons with blood of other gibbons, isoantisera have been obtained for two previously unknown blood factors of gibbon red cells designated A8 and B8 respectively. The small number of gibbons available up to the present time has prevented satisfactory statistical analysis of the findings. The findings do indicate, however, that the blood factors A8 and B8 are not related to the human-type A-B-O or M-N-S blood group systems of gibbons.     

Agglutinins for "Null" Red Blood Cells

The sera from two patients with unexplained anemia gave a pattern of agglutination in vitro which was the converse of that described for Rh-like antibodies associated with autoimmune hemolytic anemia. These sera reacted with not only Rh_null red blood cells but also U negative, Bombay and other cells lacking in usual agglutinogens. They appeared to contain antibodies directed against antigenic structures which are either absent or covered on the surface of red blood cells of the more usual types.     

Selection of "Safe" Group O Blood

One hundred random group O bloods were tested for their content of anti-A and/or anti-B saline agglutinins, "immune" antibodies and hemolysins. The screening tests which, according to the AABB Standards for a Blood Transfusion Service (4th Ed.) should be used for selection of group O blood which is used for other than group O recipients, were applied to the group O bloods.
The results seem to indicate that the saline 1:50 screening test is not a satisfactory test for (election of "safe" group O blood. The immune 1:20 screening test is probably the best test but preferably should be used in combination with the hemolysin screening test.     

"My Two-week-old Daughter Is Throwing up Blood"

Swallowed maternal blood at the time of delivery or from cracked nipples during breastfeeding is the most common cause of suspected gastrointestinal bleeding in the neonate. In this case, the Apt–Downey test is a useful diagnostic tool. The Apt–Downey test can effectively differentiate neonatal from maternal hemoglobin based on the conversion of oxyhemoglobin to alkaline globin hematin when mixed with alkali.     

杭州“7·5”公交纵火事件中血液资源管理与实践

目的采供血应急保障体系的有效运作对突发事件血液资源管理的管理的重要性。方法采供血应急保障体系的启动,掌握突发事件血液资源经历应急聚积、理性控制和平稳三个阶段特征分阶段进行有效的血液安全宣传,招募引导保留血液资源。结果 7·5事件发生后采供血应急保障体系的有效运作是应对此次事件的关键。通过本次血液资源应急管理的三阶段控制步骤,有效避免血液过期浪费的风险。回顾性分析血液报废率与同期相比无明显改变,说明此次事件中的血液安全可控。结论血站应进一步锻炼以血源和血液保障预案为核心,以后勤、信息、新闻应对等预案为辅的应急保障体系。
