记忆合金环抱器在复杂骨折治疗中的应用

对于一些特殊类型骨折以及严重的粉碎性骨折，传统的内、外固定方式难以固定，或固定效果不确切，不利于早期功能锻炼，影响骨折的愈合。NiTi记忆合金是近年来应用于骨折固定的新型内固定材料，自1998～2003年我们采’用记忆合金环抱器治疗各种复杂骨折17例，取得了满意的疗效。     

食物中毒的防制策略

食品生产及流通全球化、新的食品加工技术的应用、东西方饮食习惯的交融、自然环境（如洪涝灾害、地震灾害等）或社会环境（如战争、有毒有害物质的泄漏等）的突然改变，以及各种新的病原体和传播媒介的流行和发现，不断地给人类的食品安全和健康带来威胁，同时也给部队控制和预防食物中毒提出新的课题。

RGD多肽接枝聚复合导管桥接神经缺损的实验研究

Objective To investigate the effect of RGD peptide conjugated poly[ LA-(Glc-Lys) ]/βTCP/PLA nerve conduit for bridging peripheral nerve regeneration defect. Methods Forty-five male Wister rots were randomly divided into 3 groups, with 15 rats each. A 10 mm defect was created in the right sciatic nerve. In group A the gap was bridged by PLA tube. In group B RGD peptide conjugated poly[ LA-(Glc-Lys) ]/β-TCP/PLA nerve conduit was used to repair the defect. Autologous nerve graft was done in group C which served as control. Twelve weeks postoperatively nerve regeneration was evaluated by gross observation,electrophysiology, muscle weight and muscle morphometry of triceps surae, and ultrastructure of the regenerating nerve. Results Twelve weeks after the operation, nerve conduction velocity and muscle weight recovery of group B were better than those of group A. The differences were statistically significant( P < 0.05). There was no significant difference between group B and group C ( P > 0. 05). The results of histology and ultrastructure showed that nerve regeneration in group B and group C was significantly superior to that in group A.Conclusion RGD peptide conjugated poly[LA-(Glc-Lys)]/β-TCP/PLA conduit can achieve similar results in repairing sciatic nerve defect to that of autogentic nerve graft. It may be an ideal material to repair nerve defect.     

空心加压螺纹钉结合钢丝治疗髌骨体部横形骨折

髌骨骨折在骨科领域属常见骨折，一般累及髌骨的中1/3，常伴有分离移位，需手术内固定治疗。由于是关节内骨折，后关节面不平整容易造成创伤性关节炎，故对复位要求较高。单纯钢丝环扎因固定欠牢靠，需辅助长时间外固定，不利于膝关节早期功能锻炼，目前逐步摒弃而被张力带取代。我院自2003年2月至2006年10月采用2枚空心加压螺纹钉结合钢丝治疗髌骨体部横形骨折25例，取得良好效果。[第一段]     

北京市褐家鼠中汉坦病毒的分离和初步鉴定

肾综合征出血热(hemorrhagic fever with renal syndrome，HFRS)是由鼠类传播的自然疫源性疾病。现已证实我国主要存在汉滩型(HTN)和汉城型(SEO)汉坦病毒。近年来，北京市HFRS发病出现不断上升趋势，流行形势比较严峻。近年的流行病学研究证实北京地区存在鼠间SEO型汉坦病毒感染。为了解近期北京地区HFRS流行毒株的型别和特点，从病原学角度阐明疫情原因，我们在对北京地区宿主动物进行汉坦病毒分子流行病学调查研究的基础上，进行了病毒分离和初步鉴定。     

THE ACTION OF RADIX REHMANNIAE AND PLASTRUM TESTUDINIS ON BETA- ADRENERGIC RECEPTOR-cAMP SYSTEM

Mouse and rat pathological models were pro duced by injections of thyroid hormone (T3 0r T4, Model. I) or hydrocortisone (HC, Model II). A single subcutaneous dose of isoproterenol (ISO) caused plasma cAMP to peak in 5-15 min which was significantly higher in mouse Models I and II than in normal mice. Daily oral administration of a decoction of two Yin tonics-Radix Rehmanniae (RR) and Plastrum Testudinis (PT) reduced peak cAMP in both models. 3H.DHA binding assay re vealed significant elevations of the number of 3 adrenergic receptors in rat Models I and II. Decoc- tion RR and PT restored the peaks to normal range. Yang tonics Radix Aconiti praeparata (RAP) and Cortex Cinnamomi (CC) showcd contradictory effects on these models. It seems unlikely that the action of the two tonics promotes the dlearance of injected hormones, since injected hormone RIA iii plasma showed no differences between Yin tonics treated and untreated models. The therapeutic effects of these two Yin tonics on "Yin deficiency" syndrome of hyperthyroidism or hyperfunction of the adrenal cortex is very probably related to their actions on the O-adrenoreceptor-cAMP system as stated.     

从解剖角度探讨成年女性腹腔镜腹股沟疝修补术中子宫圆韧带的处理

<正>腹股沟疝发病人群中女性仅占6%^[1],其发生机制和临床特点与男性有着较大差异。女性腹股沟疝中股疝比例高达26.07%,远高于男性的5.09%^[2],因此发生嵌顿的比例也比较大。以往由于对女性腹股沟疝的解剖结构和临床特点认知不足,导致女性腹股沟疝的手术策略和技术基本同于男性。
