Cannabis and driving: A new perspective

Cannabis and driving is an emerging injury‐prevention concern. The incidence of driving while affected by cannabis is rising in parallel with increased cannabis use in the community. Younger drivers are at particular risk. Improvements in research methodology, technology and laboratory testing methods have occurred in the last 10 years. These cast doubt on earlier results and conclusions. Studies now show that cannabis has a significant impairing effect on driving when used alone and that this effect is exaggerated when combined with alcohol. Of particular concern is the presence of cannabis as the sole psychoactive drug in an increasing number of road fatalities and the lack of any structural response to this problem. A review of testing methods, laboratory and real driving studies, and recent epidemiological studies is presented. Suggestions for methods of further data collection and future public policy are made.

免疫调节药在肿瘤患者住院治疗中的应用分析

目的 了解肿瘤住院患者使用免疫调节药的现状，为临床合理用药提供参考。方法对2003～2005年免疫调节药应用情况运用药物使用频度（DDDs）、年均增率（AARG）等分析方法，进行统计分析。结果 免疫调节药销售金额年均增长率达106.69%。生物反应修饰剂销售金额占总金额的65.93%。生物反应修饰剂和增强免疫功能中成药用药频度相当。排序靠前的是金黄色葡萄球菌滤液注射液、参芪扶正注射液，用量上升最快的是香菇多糖注射液、胸腺素α1注射液。结论 免疫调节药是肿瘤放化疗必备用药，在肿瘤患者住院治疗中应用广泛。整体上该类药物的应用基本合理。疗效显著且作用广泛的药物成为临床首选。     

Cost and workforce implications of subjecting all physicians to aviation industry work hour restrictions: A response

In recent years, the surgical profession has attempted to incorporate into clinical practice certain techniques that the airline industry has used to improve safety. These mechanisms have proven to be valuable components of our efforts to ensure that surgical patients receive safe, high-quality care. However, as the authors of “Cost and workforce implications of subjecting all physicians to aviation industry work hour restrictions” note, it would be a mistake to extend aviation's work-hour restrictions to medicine, particularly to resident training programs.     

Studies on Toxicity of Nitroquine-Dapsone Compound and Therapeutic Effects of Folic or Folinic Acid on Toxicated Animals

The toxic effects of nitroquine-dapsone compound(NQD)in mice and dogs were studied.The therapeutic index of NQDin mice is 1911,the greatest among the 6 antimalarials tested.Thetoxic effects of NQD(50 mg/kg/day for 3 days per os)and nitro-quine in dogs were manifested by injuries on the adrenal cortexand intestinal epithelium.When folic acid(4 mg/kg/day for 4 days)or calcium leucovorinum(0.3 mg/kg/day for 4 days)were usedconcomitantly with NQD,the death rate and the incidence of dia-rrhea in the toxicated dogs were greatly reduced,the injury on theintestinal epithelium was much milder,and the goblet cells weremuch more numerous than those without treatment.The results suggestthat folic acid and calcium leucovorinum can protect the undifferen-tiated cells in the intestinal crypts from being injured by NQD.     

The relational underpinnings of quality internal auditing in medical clinics in Israel

Internal auditing is a key mechanism in enhancing organizational reliability. However, research on the ways quality internal auditing is enabled through learning, deterrence, motivation and process improvement is scant. In particular, the relational underpinnings of internal auditing have been understudied. This study attempts to address this need by examining how organizational trust, perceived organizational support and psychological safety enable internal auditing. Data collected from employees in medical clinics of one of the largest healthcare organizations in Israel at two points in time six months apart. Our results show that organizational trust and perceived organizational support are positively related to psychological safety (measured at time 1), which, in turn, is associated with internal auditing (measured at time 2).     

中药血清化学在中药及中药复方研究中的应用

中药血清化学是在传统的口服给药模式的基础上,依据中药口服后只有移行入血的成分才可能发挥药效的思路,通过综合运用现代的提取、分析技术,对药物口服吸收后含药血清中的原型药物及其代谢产物进行分析研究,从而可直接筛选和判断出中药及复方中的有效成分并据此较快速地探明其药效物质基础,同时辅助阐明中药复方的配伍机制和意义,对中药新药的研发起到加速和推动作用。文中作者总结了一些血清药物化学的成功实践经验,并对血清药物化学的研究方法进行了归纳和概述。
