Sport Concussion——The Field Evaluation
Despite a significant increase in the understanding of concussion,this injury remains one of the most complex and poorly understood. This manuscript will outline a step-by-step process for concussion evaluation to ensure subtle signs and symptoms are not overlooked. The systematic approach includes a thorough athlete history,observation of mannerisms,and palpation of the relevant anatomical regions. Special tests for neurostatus and postural control follow with manual muscle testing of the neck musculature as indicated. Finally,all athletes should be subjected to functional testing. In conjunction with the clinical examination outlined here,the return to play decision should be made under the consultation of a physician.

提高综合医院对甲型H1N1流感的诊治能力是加强救治工作的关键
据估计,近期我国新型甲型H1N1流感(以下简称甲流)的重症与死亡病例数量可能会明显攀升,防治形势严峻.前一阶段,我国针对甲型H1N1流感的防控措施积极有效,限制了疫情的传入与播散,达到了延缓、削减发病高峰的作用,为疫苗研发与人群接种、抗病毒药物的生产与贮备及做好救治准备工作赢得了时间.

脊柱结核的治疗方案存在仁智之争
脊柱结核治疗理念一直在发展、进步,目前对脊柱结核治疗原则达成了初步共识,即全身营养支持是基础,药物治疗是根本措施,手术仅是辅助手段,但也存在着很多争论[1-4].

Lesson Thirty-two New Algorithm Using Only Lead aVR for Differential Diagnosis of Wide QRS Complex Tachycardia
Making an accurate rapid diagnosis in patients with wide QRS complex tachycardia remains a signifi-cant clinical problem1. We recently proposed a new simplified four-step decision treelike algorithm to dis-tinguish between regular monomorphic wide QRS com-plex tachycardias caused by supraventricular ventricular tachycardia (SVT) and ventricular tachycardia (VT).

荧光分析法测定水发食品中过氧化氢残留量
过氧化氢是一种强氧化剂,具有消毒、杀菌和漂白等功能,被广泛使用.在食品中,根据我国<食品添加剂使用卫生标准>的规定,只允许在袋装豆腐干和生鲜牛奶的生产过程中使用,但成品中不得有过氧化氢残留[1].近年来,食品中残留的过氧化氢引起的食物中毒事件时有发生[2],而我国目前尚无定量的标准检测方法,文献报道多用滴定分析法、分光光度法[3],且费时、容易受混杂因素的影响,选择上受到一定限制.作者基于Fe(Ⅱ)与H2O2在酸性介质中,经Fenton反应产生羟基自由基,与苯甲酸发生羟基化反应产生羟基苯甲酸,在碱性介质中可产生很强的荧光,而苯甲酸本身几乎不产生荧光[4],在优化的条件下,荧光强度的增加与过氧化氢的含量有定量关系,据此建立荧光分析法测定水发食品中过氧化氢残留量.

小儿断指再植中的骨骺保护
近年来由于显微外科技术的发展,小儿断指再植已获得很高的成功率.因小儿手指短小,创伤常伤及指关节.将手指的一个关节作功能位融合或半关节成形,术后近期多可恢复较好的对指、捏夹功能,但随时间的推移,患儿逐渐长大,关节不完整的骨骺将减慢或停止发育,使伤指出现短小畸形.对功能和外观的影响也越来越明显.因而要求重视小儿伤指骨骺的保护.

儿童髋臼骨软骨病
骨软骨病遍布人体各处骨骼,多达38余种.但发生于髋臼骨骺者极为稀少.我院1981～1983年遇到2例,其中1例用改良Chiari氏骨盆切骨内移术治疗,术后随访效果良好,现介绍如下.
