核因子-κB与创伤的关系及其在法医病理学中的应用

损伤时间推断是法医病理学的一个研究热点和难点。核因子-κB(NF-κB)是一种核转录调节蛋白,参与多种炎性介质的转录和调控。近年来研究发现NF-κB与机体创伤后的反应密切相关,其在损伤后的时序性表达可望在法医病理学用于损伤时间推断。     

Delayed Reduction of Irreducible Chronic Posterolateral Dislocation of the Knee with Buttonholing of the Medial Femoral Condyle

Abstract Traumatic knee dislocations are relatively rare and almost always respond to closed reduction; however, a small percentage of knee dislocations are irreducible and in these cases open reduction is frequently required. A 65-year-old man with an unreduced posterolateral knee dislocation with laterally dislocated patella was seen 3 weeks after a motor vehicle accident. Medial femoral condyle was found buttonholed through the medial capsule together with the medial collateral ligament and lying in the medial joint space that allowed posterior rotary dislocation of the joint. Both cruciate ligaments and medial meniscus were torn. There was no evidence of any vascular or nerve injury. Reduction was accomplished by removal of the capsuloligamentous structures which were incarcerated in the trochlea and intercondylar notch and by excision of meniscal tear. Following posterior cruciate ligament reconstruction with patellar tendon autograft, lateral patellar release, vastus medialis advancement, and gracilis transfer were done.     

外伤性肝破裂的救治

目的 分析创伤性肝破裂外科多种干预治疗的效果。方法 总结分析1982-2002年我院收治创伤性肝破裂76例的救治方法和病死率。其中Ⅲ级以上的严重肝破裂46例(60．53％)。手术治疗56例，手术方式包括单纯修补、清创性肝切除、规则性肝切除、肝周填塞止血；非手术治疗20例。结果 手术组：治愈44例，术后并发症17例均经保守治疗治愈，死亡12例，其中术中死亡2例；非手术组：治愈12例，好转6例，2例失访。全组治愈64例，死亡12例，病死率15．8％。结论 Ⅰ-Ⅱ级单纯性外伤性肝破裂可保守治疗；手术是治疗创伤性肝破裂的主要措施，正确的手术方式，积极处理合并伤，重视综合治疗可提高救治成功率。     

2 294名军人伤害住院情况分析

目的：对某区部队伤害住院患者进行流行病学特征分析，提出预防建议。方法：应用各医院上报军区统计中心的数据库资料进行分析。结果：意外损伤、军事训练伤、交通伤和烧烫伤是导致部队伤害住院的四大主要因素。伤害主要发生在18—23岁(占62．16％)之间，干部意外损伤、交通伤和锐器伤高于战士，军训伤则战士明显高于干部。结论：部队要重视和加强伤害的预防工作。     

Continuous recording of urethral activity in healthy female volunteers

The pressure variations at the maximal urethral closure pressure (MUCP) were continuously recorded in healthy female volunteers by means of a two-point microtip transducer catheter for one hour. Before the investigation a normal voiding was assured objectively and bladder instability was excluded. All women showed pressure variations both at the MUCP and more distally. The pressure variations, from 3 to 66 cm H₂O, showed rhythmicity and three frequency ranges could be identified. Slow pressure waves with a frequency of one in eight to 19 minutes were observed. Relatively fast-pressure waves were observed (one every one to four minutes) and relatively fast-frequency pressure waves were observed (rate: one to eight per minute). The pressure variations of the urethra seem to be an aspect of normal urethral physiology possibly contributing to continence and urinary tract infection prevention.     

A population-based study of repeat hospital admissions due to interpersonal violence for children aged 0–9 years

To assess the magnitude and nature of interpersonal violence resulting in hospitalisation of children and to identify subgroups at risk of repeat hospital admissions, a population-based, retrospective study of all violence hospitalisations in Western Australia for children aged 9 years or less was undertaken, using the 1990–2004 linked data retrieved from the Western Australian Mortality Database and the Hospital Morbidity Data System.
Of the 747 patients aged <10 years incurring 834 hospitalisations for the consequences of violence during the study period, 570 (76%) were less than 4 years of age. A total of 43 deaths from violence were recorded and 74 (9%) patients were admitted for more than one episode of violence. Victims aged 0–4 years from rural (hazard ratio [HR] = 2.72; 95% confidence interval [CI] 1.35, 5.43) and remote parts (HR = 2.79; 95% CI 1.25, 6.25) of the state were at increased risk of a subsequent admission for violence compared with those residing within the metropolitan area. Indigenous children aged 5–9 years were significantly more likely (HR = 3.57; 95% CI 1.14, 11.13) to incur a second hospitalisation for violence than their non-Indigenous counterparts. The identification of young victim subgroups at high risk of repeat hospitalisations is important for developing intervention strategies to reduce the burden of interpersonal violence. Young children aged 0–4 years living in rural and remote locations and Indigenous children aged 5–9 years should be specifically targeted for attention.     

儿童陈旧性孟氏骨折的手术治疗

目的:通过研究火器伤所致骨折患者的治疗及预后情况,探讨如何选择合理方法对其进行及时有效的治疗。方法:对25例火器伤所致骨折患者的治疗及预后情况进行回顾性总结分析,其中男18例,女7例;平均年龄36.2岁。骨折的部位为股骨骨折9例,胫骨骨折7例,肱骨骨折2例,骨盆骨折2例,锁骨骨折1例,椎体骨折1例,尺、桡骨骨折1例,髋关节骨折1例与膝关节损伤1例。骨折类型为未移位1例,移位2例,粉碎性10例,粉碎且移位6例,骨缺损6例。19例接受了骨科手术治疗,其他6例接受了清创治疗。10例采用外固定架固定,7例行内固定,4例行管形石膏固定,2例骨盆与髋臼骨折采用牵引治疗,2例锁骨骨折应用锁骨带治疗。结果:25例患者获得了平均4.2年的随访,18例骨折Ⅰ期愈合,6例需后期手术促进骨折愈合,1例截肢。有5例需要后期手术覆盖创面。大的并发症包括2例骨不连,4例延迟愈合,3例周围神经功能受损。结论:骨折固定方法的选择与骨移植是治疗火器伤所致的骨折与骨缺损的一项很有效的方法。     

改良(足母)趾腓侧皮瓣修复拇手指指腹缺损

目的介绍改良躅趾腓侧皮瓣修复拇、手指指腹缺损的手术方法。方法对15例拇、手指指腹缺损的患者，采用改良的躅趾腓侧皮瓣移植修复。该皮瓣在传统躅趾腓侧皮瓣设计方法基础上，将皮瓣腓侧缘及近端分别向背侧及趾蹼侧移动，从而避开口径细小又紧贴于皮下的躅趾腓侧浅静脉，直接游离第一跖背浅静脉；皮瓣的动脉和神经游离仍以常规方式进行。结果术后15例皮瓣全部成活，未发生动、静脉危象。12例获得4～11个月随访，3例失访。手功能评定：优10例，良2例。皮瓣两点分辨觉为4～8mm，12例对皮瓣外形满意。供区行走无影响，步态正常。10例对供区外观满意，2例欠满意，其中1例蹲趾腓侧偶有触痛。结论应用改良躅趾腓侧皮瓣可显著降低手术难度，提高成功率。
