肝病患者血浆凝血酶原时间及其INR值的探讨

目的 :探讨凝血酶原时间 (PT)及其国际标准化比率 (INR)在各种肝脏疾病中的变化。方法 :采用含钙凝血活酶对肝病患者血浆用凝固法测定 ,报告INR值。结果 :肝硬化、肝癌和肝炎患者与正常对照组比较 ,PT延长均具有显著性 (P <0 .0 5～P <0 .0 1)。结论 :PT测定不仅具有外源性凝血系统筛选试验的意义 ,也可以作为肝病患者对病程进展及严重程度的参考指标。     

电针肾俞、膈俞、百会穴对拟血管性痴呆学习记忆障碍小鼠水迷宫实验的影响

目的　观察电针肾俞、膈俞、百会穴对拟血管性痴呆小鼠学习记忆障碍的影响。方法　复制脑缺血再灌注拟血管性痴呆小鼠模型 ,并电针肾俞、膈俞、百会穴 ,分别于术后 7天、15天、30天 ,与药物喜德镇对照 ,采用水迷宫法 ,记录游全程时间、错误次数。结果　造模导致了小鼠学习与记忆能力下降 ,表现为游全程时间延长 ,错误次数增加 ,且随着观察时间的延长 ,这种改变逐渐加重。电针和喜德镇均可使模型小鼠的游全程时间缩短 ,错误次数减少 ,但电针组于 7天和 30天时 ,成绩显著优于药物组。结论　电针肾俞、膈俞、百会穴对模型小鼠学习与记忆能力下降有改善和提高作用     

重度蒸汽吸入性损伤犬伤后肿瘤坏死因子水平的改变及其意义

目的研究蒸汽吸人性损伤犬伤后血浆肿瘤坏死因子水平的改变及其与吸入性损伤呼吸循环功能受损程度的关系.方法取犬15条,以蒸汽致重度吸入性损伤,分别于伤前、伤后1h、2h、3h、4h观察有呼气相气道阻力(RE)、心率(HR)、心输出量(CO)、动脉血氧分压(PaO2)、血浆TNF水平;伤后4h致死动物,取肺做病理检查.结果伤后1hTNF、RE升高,HR、CO、PaO2下降;TNF与RE正相关(r=O.965,P<O.01),与CO负相关(r=-0.824,P<O.05).结论严重蒸汽吸入性损伤激发TNF分泌,这是诱发肺损伤及循环系统甚至全身器官功能障碍的重要原因.

Considerations for inter-hospital extracorporeal cardiopulmonary support resuscitation and transport

The availability of commercial, pre-packaged extracorporeal cardiopulmonary support (ECPS) circuits, which are simplified for rapid set-up and priming, has made the intra-hospital resuscitation of moribund patients routine. The successful utilization of this technology in the emergent setting requires planning and the coordination of personnel familiar with the technology. Many issues must be addressed when a patient requiring life-sustaining support utilizing this technology at an outlying hospital, must be transported while on ECPS. After reducing the size and weight of the ECPS cart and obtaining Federal Aviation Administration approval for use during aeromedical transport, the Emanuel Hospital Mobile Surgical Transport Team (MSTT) was able to extend the use of emergency cardiopulmonary bypass to outlying medical facilities. The patients selected for transport, using ECPS, are a group of patients with a potentially survivable pathology unlikely to survive inter-hospital transport without such measures. This report describes our experience with inter-hospital transport of patients on ECPS with special emphasis on transport considerations.     

Association of heterotopic neuroglial tissue with an arachnoid cyst in the internal auditory canal

An arachnoid cyst arising within the internal auditory canal, or within the cerebellopontine angle and subsequently extending into the internal meatus and enlarging it, is a rare occurrence. Nevertheless, the neurootologist and the neurosurgeon have an interest in its existence because its clinical manifestations are identical with the ones produced by a schwannoma, involving overwhelmingly the cochleovestibular nerve in that region. An equally rare observation in that location is the presence of ectopic neuroglial tissue. The two can occur independently or in combination. Examples of such lesions are presented, and their possible pathogenesis is discussed.

列车乘务员SCL—90评定结果分析

采用ＳＣＬ—９０症状自评量表对某铁路分局４６７名列车乘务员的心理卫生状况进行了分析。结果显示总均分、阳性症状均分、阳性项目数、九组症候群因子分、达到或超过中等严重程度的发生频数均显著高于对照组。经多元逐步回归分析,仅细菌总数和二氧化碳对列车乘务员心理卫生状况有一定影响,其原因多与工作环境的不良因素和工作性质有关。     

Treatment of infected left ventricular assist device using antibiotic-impregnated beads

There is no well-established therapy for treating infections of heart-assist or artificial heart devices, a serious problem with life-threatening consequences. We used a promising new approach in which antibiotic-impregnated polymethylmethacrylate beads were placed around an implanted left ventricular assist device to control an external blood pump infection in a bridge-to-transplant patient. In this case report, we describe the potential of antimicrobial-impregnated polymethylmethacrylate beads for in situ control of infections involving external surfaces of cardiovascular devices.
