Lugol液染色对食管早期癌和癌前病变的诊断价值

目的 探讨Lugol液染色对食管早期癌和癌前病变的诊断价值。方法 对45例食管黏膜可疑病变经内镜以2％Lugol液喷洒染色，观察黏膜染色情况，并取活检送病理组织学检查。结果 45例食管病变染色后，39例呈浅染色或不染色，其中食管癌8例（食管早期癌5例，进展期癌3例），Barrett食管5例，轻至中度不典型增生1l例。本组Lugol液染色对食管早期癌和癌前病变的检出率达46．7％。结论 内镜下应用Lugol液染色结合活检有助于食管早期癌和癌前病变的诊断，且操作简便，具有重要的临床价值。     

Use of paracervical analgesia for outpatient hysteroscopic surgery: A randomized, double-blind, placebo-controlled study

Twenty-five women receiving sedation for outpatient hysteroscopic polypectomy were injected with 0.25% bupivacaine 10 mL (paracervical group) and another 25 received the same volume of saline (control group) at the cervical fornix. Both groups were given target-controlled propofol sedation during the procedure. More propofol (mg/min) was needed for adequate anesthesia in the control group compared to the paracervical group (6.5 versus 4.6). In addition, the postoperative pain scores were lower in the paracervical group than in the control group. Hemodynamic changes and postoperative side effects were similar in the two groups. This prospective, randomized, double-blind, placebo-controlled study confirmed the effective use of paracervical blocks. This approach has the effect of reducing the amount of intraoperative propofol and decreasing postoperative pain in outpatient hysteroscopic surgery.     

听觉诱发电位指数、脑电双频指数对异丙酚麻醉下患者术中体动反应的预测

目的评价听觉诱发电位指数(AAI)、脑电双频指数(BIS)预测异丙酚麻醉下患者术中体动反应的可能性。方法择期行妇科手术全麻患者28例,ASAⅠ或Ⅱ级,年龄24-62岁,体重46- 71 kg,术前2 h口服咪达唑仑10 mg,入室后以血浆靶浓度3．5μg/ml靶控输注异丙酚、静脉注射芬太尼2μg／kg及维库溴铵0．1 mg／kg麻醉诱导,气管插管后,调整异丙酚血浆靶浓度维持BIS 40-60。切皮后不再追加肌松剂,观察患者术中头面部及四肢的体动反应,记录体动反应发生前、后2min内BIS、AAI的最大值(BISmax、AAImax)及此时段内BIS>75、AAI>40的次数及出现时间。记录术中当BIS>75、AAI>40时前、后2 min内有无体动反应发生及发生时间。结果12例出现体动反应,体动前、后2 min内BISmax为63±16(4例BIS>75,33．3％),AAImax为48±11(12例AAI>40,100％)。麻醉维持过程中,出现14次BIS>75,并发体动反应4次(28．5％),BIS反应时间较体动时间滞后(84±19)s;出现AAI>40者28次,并发体动者12次(42．8％),AAI反应时间较体动时间滞后(13±3)s。结论异丙酚麻醉下BIS、AAI反应时间较体动发生时间滞后,不能预测术中体动反应的发生。     

The modified outside-in suture: vertical repair of the anterior horn of the meniscus after decompression of a large meniscal cyst

This article describes a modified suture technique designed for the vertical repair of the anterior horn of the meniscus after arthroscopic decompression of a large meniscal cyst. This procedure comprises of three steps: first, the meniscus was pierced vertically using a suture hook and a No. 0 PDS suture. Second, both ends of the No. 0 PDS on the femoral and tibial surfaces of the meniscus were pulled to the outside of the joint capsule using a spinal needle preloaded with suture material. Finally, a skin incision was made adjacent to the suture materials, and both ends were tied. We recommend this technique not only for the vertical repair of the anterior horn of the meniscus after decompression of large meniscal cyst, but also to repair a longitudinal tear of the meniscus.

APACHEⅢ评分对脑卒中病人预后的评估及相关因素的研究

目的 观察APACHEⅢ评分系统对脑卒中病人预后的预测效果，并对其相关影响因素进行分析．方法 136例脑卒中病人入院后在接受治疗前进行APACHEⅢ评分，再分别计算出每一例的预测死亡危险度；入院7d内每天作1次APACHEⅢ评分，实际观察结果分为死亡和存活两种．最后按病灶的位置分为两组：中线组和非中线组；再按脑出血的体积或脑梗死的容积分为两组：大病灶组和小病灶组。然后进行统计学处理．结果 死亡组的APACHEⅢ评分明显高于存活组；中线组的APACHEⅢ评分显著高于非中线组，其中，中线组的急性生理学评分和神经学评分均显著高于非中线组，而两组的年龄及慢性健康状况评分无显著性差异．大病灶组的评分高于小病灶组，其中，大病灶组的急性生理学评分和神经学评分均盟著高于小病灶组，而年龄及慢性健康状况评分无显著性差异．预测死亡危险度为0．4时准确度最高．结论 APACHEⅢ评分系统对评估脑卒中病人病情危重程度及预测死亡危险度具有重要的参考价值．     

Ruptured distal anterior choroidal artery aneurysm.

Ruptured aneurysms of the distal anterior choroidal artery (AchA) are extremely rare and management is dictated by clinical presentation. This report describes a rare patient with a distal AchA aneurysm and subarachnoid and intraventricular haemorrhage. A 60-year-old woman presented with a sudden onset of severe headache and vomiting. No aneurysms could be found on initial angiograms. A repeat angiogram performed 10 days after admission demonstrated an aneurysm in a branch of the cisternal segment of the left AchA without a definite neck. Surrounding vessels showed multifocal stricture and dilatation. Microsurgical clipping was not performed because the patient died suddenly due to pulmonary failure. The aetiology of the aneurysm in this case and surgical strategy are discussed.     

孕妇产前心理状态与需求的调查

目的对孕妇产前心理状态及其影响因素进行调查和评定,以探讨心理因素对分娩方式的影响。方法用综合医院焦虑/抑郁情绪测定量表,采用调查问卷法。结果有焦虑/抑郁症状组与无焦虑/抑郁症状组剖宫产率分别为80%和30%,差异有非常显著性(χ2=25.25,P<0.01);两组产后出血和新生儿阿氏评分,差异也有非常显著性,对婴儿的哺乳喂养方式(母乳、混合、人工)两组亦存在显著性差异(χ2=7.36,P<0.05)。结论产前对有焦虑/抑郁障碍的孕妇进行科学、整体的护理,实施有效的心理干预,可以减轻甚至消除焦虑/抑郁情绪,使孕妇处于最佳身心状态,保障母婴平安度过分娩期。     

上海市闵行区性病门诊本地和外来病人的比较研究

目的分析和比较上海市闵行区性病门诊本地与外来病人的流行病学特征。方法对2001~2004年上海市闵行区3家设有标准化性病门诊的公立医院进行门诊病历的回顾性分析。结果外来人口约占全部性病门诊病人的50%,其中女性病例占18.2%,未婚者占23.8%,均高于本地同类人员的比例;外来病人年龄偏低,多重感染者比例较高;男女外来病人与本地病人的首诊原因和症状排位相同,均以淋病感染为主;外来病人随访率(81.2%)较本地病人低(86.0%)。结论性病门诊本地和外来病人在人口学特征、诊疗行为上存在差异,防制措施应有所不同和侧重。     

系统干预对老年痴呆患者激越行为的影响

目的探讨系统干预对老年痴呆患者激越行为的影响.方法将67例老年痴呆患者随机分为观察组(35例)和对照组(32例).对照组行常规药物治疗和康复训练,观察组在此基础上实施系统干预,连续3个月后应用激越问卷(CMAI)评价护理效果.结果干预前,两组CMAI评分差异无显著性意义(P>0.05);干预3个月后,两组CMAI评分均显著低于干预前(均P<0.05),但观察组激越行为改善程度显著优于对照组(P<0.05).结论系统干预能更为有效地缓解老年痴呆患者的激越行为,稳定病情,提高其生活质量.
