Clinical observations on the use of the Chinese herbTripterygium wilfordii Hook for the treatment of nephrotic syndrome

A preparation of extracts from the root of the Chinese medicinal herbTripterygium wilfordii Hook was administered orally at a dose of 1 mg/kg body weight per day to 13 children with idiopathic nephrotic syndrome. Eight children, including 4 who were steroid resistant, went into remission which was maintained in 4 for up to 3 years after withdrawal of treatment. In 3 children the proteinuria lessened with the return of plasma protein concentration to normal, and in 1 child this improvement was maintained for 4 years after treatment ceased. No serious side-effects were noted, but a temporary anti-fertility activity has been noted in other studies of both men and women.     

How do clinicians learn to request permission for autopsies?

A postal survey of 434 clinicians at four local hospitals was undertaken in order to identify the methods by which clinicians learn how to request permission for hospital autopsies and to assess the preferred techniques and timing of relevant communication skills training. The majority of 128 responding clinicians had learnt through personal experience with some assistance from senior colleagues and peers. Few clinicians appeared to have learnt through formal training. The preferred methods for the provision of communication skills training were training in small groups (such as seminars or tutorials) and observation of clinicians at work. The most desirable time for the provision of this training was considered to be between the beginning of the final undergraduate year and the end of the pre-registration house officer year. The communication skills training provided within medical education is in need of improvement. More emphasis should be given to clinical-task- or situation-specific applications such as requesting permission for autopsies.     

基础医学教师课堂教学质量评价

为了了解本科教师的教学质量和教学效果 ,教学专家和学生评价了 14 7位基础医学教师。结果显示 ,讲师以上职称教师的教学质量明显好于初级职称教师 (P<0 .0 5 ) ,高级职称教师教学的科学性、艺术性和思想性明显好于讲师和助教 (P<0 .0 5 )。文章还对教学中存在的问题和对策进行了讨论。     

Why do long-distance runners not have more bone? A vital biomechanical explanation and an estrogen effect

Inanimate structures cannot detect and repair their fatigue damage or microdamage, so to minimize it they need more structural material and strength. Living bone handles this matter differently. Bone modeling drifts adapt bone architecture and strength to the loads on bones in ways that tend to keep strains from exceeding a “modeling threshold” range. Strains (or equivalent features) above that threshold switch mechanically controlled modeling ON. Where strains stay below that threshold, this modeling goes OFF. Repeatedly loading-deloading a bone causes microdamage in it, and basic multicellular unit (BMU)-based bone remodeling normally repairs it. Where strains stay below an operational “microdamage threshold,” remodeling can repair whatever microdamage happens for as long as it happens. Strains above that threshold can cause too much microdamage to repair completely and lead to fatigue fractures of trabeculae or whole bones. The modeling threshold normally lies comforably below the microdamage threshold. Since modeling normally adjusts bone architecture to keep strains from exceeding the modeling threshold, this keeps strains below the microdamage threshold, too, and voluntary activities do not cause more microdamage than remodeling can repair. Therefore, long-distance runners do not need more bone mass and strength than nonrunners of comparable age, sex, and body size.     

上海市卢湾区部分医院X-CT诊断医疗照射频率分析

目的了解我区部分医院X—CT检查占所有放射检查的比例，并分析2002至2004年X-CT各部位阳性检出率。方法分析X-CT诊断医疗照射频率的调查资料。结果CT检查占所有放射检查的比例为23．04％；除个别部位外，大部分阳性检出率均有所提高。结论X—CT检查的频率应予以控制，通过质控提高阳性检出率。
