IABP在心脏直视手术围术期低心排的应用

为了探讨主动脉内球囊反搏（IABP）治疗心脏手术围术期低心输出量综合征（LCOS）的临床疗效,对16例心脏手术围术期LCOS患者,经过股动脉放置IABP导管于降主动脉内进行左心辅助治疗,IABP治疗前、后监测患者连续有创动脉收缩压（SABP）、有创平均动脉压（MABP）、中心静脉压（CVP）、动脉血氧分压（PaO2）、心率（HR）、尿量和血管活性药物的使用。结果显示,IABP辅助治疗时间25h～116h,平均（78．5±40．5）h。行IABP治疗后,SABP、MABP、PaO2较术前明显提高（P〈0．05）,HR、CVP明显下降（P〈0．05）,尿量增加,血管活性药物使用量明显减少（P〈0．05）,12例患者心功能好转而脱离IABP,11例（69．3％）存活,4例死于心源性休克,1例死于多器官功能不全综合征（MODS）。提示正确及时地使用IABP能明显改善心脏手术围术期LCOS患者的血流动力学指标,减少血管活性药物的使用,建议对有适应证者应尽早应用,适时撤离。     

超声心动图与心血管造影X线引导下先心病介入封堵治疗的比较

目前先天性心脏病介入治疗已成为介入心脏病学的新热点,而先心病介入治疗离不开影像学引导,目前临床上常用的影像学引导方式主要有超声心动图和心血管造影两种,本文针对两者优缺点,从治疗方式、疗效、费用等方面进行比较,为临床治疗思路提供借鉴。     

古埃及疾病医治理念透析

疾病医治理念是古埃及文明的重要组成部分。古埃及人针对不同类别疾病有着相应的医治理念：药物、魔法与意志是内科疾病的医治理念;河渠原理是医治外科疾病的理念;对于治疗心理疾病主要是寻求神灵的拯救;预防疾病的理念是保持圣洁。挖掘、梳理这些医治理念,可以加强医学史的学科建设,对某些疾病的治疗有参考价值。     

Issues Involving Informed Consent for Research Participants with Alzheimer’s Disease

Alzheimer’s disease is the most common form of dementia which is estimated to impact 350,000 people over 65 years of age in Canada. The lack of effective treatment and the growing number of people who are expected to be diagnosed with Alzheimer’s disease in the near future are compelling reasons why continued research is in this area is necessary. With additional research, there needs to be greater recognition of the complexity of seeking ongoing informed consent from those with Alzheimer’s disease. This complexity is because the impairment of memory and cognitive ability does not diminish in a linear manner, but rather fluctuates between periods of impairment and relatively normal cognitive lucidness. There is limited discussion in the guidelines of those progressing from early stages of Alzheimer’s disease who have intermittent cognitive function. Guidelines to research and Research Ethics Boards require further development to facilitate researcher including those with Alzheimer’s disease while protecting this growing pool of potential participants.     

Impulsivity as a predictor of newly-diagnosed peptic ulcer disease: A prospective cohort study

We examined the role of impulsivity in the development of peptic ulcer disease (PUD). The subjects were initially healthy 4636 hospital employees aged 19–62 who responded to a questionnaire on personality, health habits, mental health, and PUD in 1998 and 2000. We used multivariate logistic analyses to determine the relationship between impulsivity and newly-diagnosed PUD among those employees who did not have PUD at baseline. Impulsivity was assessed with the Karolinska Scale of Personality. High level of impulsivity was associated with increased 2-year incidence of doctor-diagnosed PUD after adjustment of age, gender, education and shift work (odds ratio = 2.42, 95% confidence interval = 1.21–4.82). Additional adjustment for the effects of smoking, alcohol consumption, BMI, physical activity, minor psychiatric morbidity and diagnosed depression and other psychiatric disease had little effect on this relationship. The present study suggests that impulsivity may be a risk factor for the development of PUD.     

呼吸危重症临床决策中的若干问题

在临床实践中,呼吸危重症的诊断和治疗存在着一些不同的观点。就其中某些热点问题,如慢性阻塞性肺疾病合并哮喘的诊断和机械通气的指征、肺栓塞的诊断、急性呼吸窘迫综合征的治疗、呼吸重症监护病房的建设和呼吸危重症的伦理学问题进行阐述,以期提高对呼吸危重症的认识。     

骨科疾病诊治中的临床思维

医学哲学是对医学科学成就总的概括,并以此为基础探讨生命活动和病程的一般规律,研究医学科学的思维方式,直至疾病预防、诊断治疗。同时研究辩证规律和范畴在医学科学中的表现,从而指导骨科医师解决在骨科疾病诊治中遇到的诸多问题,并有助于形成正确的临床思维。结合临床工作体会,探讨医学哲学在骨科疾病诊治临床思维中的应用。     

从能量观疾病

能量在机体的各种离子、分子、细胞、器官、组织、系统间协调分布,共同维持着健康状态。某一病因作用于人体后,“协调分布”会被不同程度地打破,当超过一定的阈值,就会产生疾病。对于人体,各种能量的直接表现形式和能量的携带者——各种营养物质,都与疾病之间有着千丝万缕的联系。从“能量”角度,我们既可进一步探讨尚未阐述清楚的疾病发生机制,又可以设计更为完美的治疗方案与医学仪器。     

非传统理念指导下的传统技术导致应用医学重大课题的突破--关于2005年诺贝尔生理学或医学奖

发现幽门螺杆菌(Helicobacter pylori,以下简称Hp)导致慢性胃炎和消化性溃疡,是沃伦和马歇尔获得2005年诺贝尔医学奖的原因.他们在1982年得出的这一假说,违反了关于这一类慢性病传统的发病机制理念.可能因为这一理念的反传统性,其假说被世界同行基本接受大概经历了20年时间.值得强调的是,对HP的观察、分离、培养、鉴定和人体试验,以及它与疾病相关的诊断、治疗、临床流行病学等研究,应用的都是传统的医学技术.从而表明,即使到了20世纪80年代,传统技术仍能导致诺贝尔奖级科研成果的出现.
