后囊连续环形撕囊在儿童人工晶体植入术的应用

后发障是儿童白内障最常见的并发症，是导致术后视力下降的主要原因，故降低后发障的发生率对提高术后视力及减少弱视的发生非常重要，以往文献报道大多是术后行ND-YAG激光后囊切开术来治疗后发障。笔者近年对儿童白内障采用白内障摘除人工晶体植入联合后囊连续环形撕囊术预防人工晶体术后后囊混浊，效果肯定，报告如下。     

低调做人，踏实做事——访上海麦迪逊医疗器械有限公司总经理赵在玉先生

从2004年下半年到2005年上半年,世界超声联合会以及中华医学会超声学会共同举办了5次较大规模的超声学术研讨会,上海麦迪逊医疗器械有限公司作为唯一的赞助商承担了全部研讨会的组织运行工作,投入了很大的人力、财力、物力,但是在研讨会上却没有看到他们任何与商业有关的活动.上海麦迪逊的这种作法引起了我的注意,于是我找来麦迪逊公司的简单资料:     

Coping with economic crisis: policy development in China and India

This paper explores health policy options in response to economiccrises in developing countries. The paper is based upon thepremise that policy is best pursued within a broad understandingof the determinants of health of populations. To provide anempirical base for analysis, the health status and health caresystems of China and India are compared. A conceptual frameworkon the determinants of the health status of populations is thendeveloped, incorporating both the performance of health caresystems and non-medical factors which influence health. Usingthe China and India experiences, the paper reviews the strengthsand weaknesses of traditional tools used in the analysis ofhealth policy. Significant policy change, it is argued, is bestimplemented through structural change of several health caresystem components simultaneously. Health policy analysis, itis further argued, must consider the broader political economyof the society. Moreover, there remain many imperfectly understoodsociocultural aspects of behaviour which enable some familiesto produce good health despite economic constraints. The paperconcludes that economic crisis presents an opportunity for astructural review of a society's health systems. Health policyoptions in response to economic crisis cannot be confined tothe health care sector. Rather, health policy should be viewedas only one, perhaps important, element of a package of socioeconomicpolicy options. Critical to policy choices are reliable informationon the condition of the poor and high political priority tominimize the adverse impact of economic crisis on the health,nutrition and social welfare of disadvantaged groups.

Dry skin in dermatology: a complex physiopathology

Dry skin (xerosis) is a common dermatosis affecting people of varying skin types and ages and various areas of the body. It is associated with both skin thickening and skin thinning and is triggered by both exogenous (e.g. climate, environment, lifestyle) and endogenous (e.g. medication, hormone fluctuations, organ diseases) factors. Skin requires a water content of 10–15% to remain supple and intact. This water is either ‘static’ (i.e. bound) or ‘dynamic’. The predominance of hydrophobic substances in intercellular constituents is a means of regulating the humidity of the skin. Emollients, highly effective treatment adjuncts in the management of all dry skin disorders, help to restore damaged intercorneocyte lipid structures and increase the water content of the skin, helping to reduce scaling and improving its barrier function.
