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.     

16层螺旋CT对肋骨骨折的诊断价值

随着工业化进程的加速及交通事故的增加,胸部创伤日渐增多。国内报道在45 569例创伤中,胸部创伤占1·47%[1],其中肋骨骨折非常常见。随着螺旋CT检查临床应用日趋广泛,其高敏性、快速成像的特性及强大的后处理功能越来越在肋骨骨折中显现重要作用。本文对53例肋骨骨折患者的16层     

继发性肝癌的外科治疗

目的探讨继发性肝癌的手术适应证和方法。方法对52例继发性肝癌的临床病例资料进行回顾性分析。结果分别采用了左半肝切除、右半肝切除、左外叶切除、右前叶切除、右后叶切除和肝楔形切除术。术后1、3、5年的生存率分别为28.3%、19.4%和11.9%。结论对适合手术的继发性肝癌,行肝切除术可以获得满意的效果。     

An exceptional postoperative gastric tube bleeding after esophageal resection for cancer

A case of gastric tube bleeding after an Ivor-Lewis esophagectomy with gastroesophageal anastomosis is reported. During the early postoperative course, the patient had a gastric tube stasis that improved progressively. The subsequent onset of a serious and intermittent hematemesis, which was endoscopically deemed to be the result of a hemorrhagic gastritis, required multiple blood transfusions. The evolution to a severe hemodynamic instability obliged us to reoperate on the patient. During surgery, a band-related obstruction of the first jejunal loop with local signs of vascular hypertension was noted. As soon as the obstruction was solved, the gastric bleeding stopped. The authors discuss the clinical aspects and physiopathology of the gastric tube bleeding and, in particular, they evaluate the influence of the intestinal obstruction with vascular involvement on the development of this exceptional and severe complication.     

重症肌无力术后机械通气脱机方法的比较

目的:比较重症肌无力胸腺切除术后经验性脱机和程序化脱机在机械通气(MV)撤机的临床效果。方法:重症肌无力胸腺切除术后行机械通气的患者67例,根据脱机方式不同分为经验性脱机组和程序化脱机。比较两种脱机方法的MV时间、监护室住院时间、脱机成功率、呼吸机相关性肺炎(VAP)发生率和住院死亡率等差异。结果:两组重症肌无力术后机械通气患者比较,程序化脱机组比经验性脱机组MV时间、监护室住院时间和总住院时间均有明显缩短(P<0.05);VAP发生率和住院死亡率方面,程序化脱机组均明显低于经验性脱机组(均P<0.05)。结论:重症肌无力胸腺切除术后机械通气时采用程序化脱机能明显缩短MV时间和监护室住院时间,提高脱机成功率,降低VAP发生率和住院死亡率,值得临床推广。     

心脾综合征的多普勒超声心动图诊断

目的:探讨多普勒超声心动图对心脾综合征的诊断价值,分析其心脏伴随畸形漏诊及误诊原因,提高对心脾综合征诊断的准确率。方法:本文总结了221例心脾综合征患儿的超声检测结果,并与其心血管造影或磁共振检查结果进行对照。结果:超声心动图诊断为心脾综合征与心导管或磁共振结论符合者199例(占90.0%),诊断不符合者22例(占10.0%)。结论:多普勒超声心动图可以较准确地诊断心脾综合征,但对其心脏伴随畸形检出的准确率尚待进一步提高。
