急性梗阻的左半结肠癌Ⅰ期切除吻合体会

目的探讨左半结肠癌急性梗阻Ⅰ期切除吻合的Ⅰ临床应用价值。方法对1988年1月至2006年12月24侧实施左半结肠癌急性梗阻Ⅰ期切除吻合手术患者的资料进行回顾性总结。结果24例均未发生吻合口漏，仅3例发生切口感染，经局部换药处理Ⅱ期愈合。结论积极的术前准备、术中彻底的肠减压能为左半结肠癌急性梗阻Ⅰ期切除吻合提供安全保证.     

鼻胃管胃肠减压在择期腹部手术中的应用价值

鼻胃管胃肠减压曾被常规应用于择期和急诊的腹部手术后，目的是预防急性胃扩张的发生、治疗梗阻、降低吻合口压力等。但是，鼻胃管置入也会带来一些副作用，如呼吸道并发症、胃-食道反流、体液和电解质的丢失、声带的损伤，以及越来越被重视的患者的不适感。近年来的研究结果也对择期的腹部手术后常规应用鼻胃管胃肠减压提出不同的看法。现重新评价应用鼻胃管胃肠减压的理论基础及相关临床研究的结果，并对鼻胃管胃肠减压在择期腹部手术中的价值作一综述。     

预适应锻炼对急进高原新兵脑功能的保护作用

目的探讨预适应锻炼对新兵急进高原后脑功能的改善作用。方法120名新兵随机分为4组:对照组、面罩组、运动组和面罩复合运动组。在进入高原前,面罩复合运动组佩带低氧呼吸器小步快走10 min,休息5 min后重复进行,上、下午各进行4次,连续进行7 d;面罩组、运动组分别只佩带低氧呼吸器或单纯运动。在空运进入高原后,比较进高原前、后的神经行为核心测试组合系统指标的改变,并对急性高原反应症状进行分析。结果使用低氧呼吸器复合小步快走5 min时动脉血氧饱和度可降到(80.5±5.7)%,达到预缺氧的目的。新兵进入3 658 m高原后,对照组、面罩组和运动组的数字跨度、目标追踪测试分值明显下降(P<0.05),而面罩复合运动组无明显改变(P>0.05);各组进藏前、后的简单反应时、数字译码和视觉保留均无显著性改变(P>0.05),手敏捷度则显著提高(P<0.05)。对照组、面罩组、运动组和面罩复合运动组的急性高原反应发病率分别为13.3%、20.0%、20.0%、3.3%。结论进入高原前,应用低氧呼吸器辅以适当运动,能改善急进高原人群的即时听觉记忆能力和手部运动的速度及准确性,避免部分脑功能的损害,并使急性高原反应发病率呈降低趋势。     

Minor Psychiatric Morbidity, Its Prevalence and Outcome in a Cohort of Civil Servants A Seven-year Follow-up Study

During the years 1979–1986, a cohort of direct entrantexecutive officers in the Civil Service were followed up toexamine the prevalence and outcome of minor psychiatric morbidityin an occupational setting. All studies using epidemiologicalstandardized research methods agree, that prevalence rates arehigh in occupational settings. As in primary care settings,half of the illness episodes followed a chronic course, whichemphasizes the need for early detection and prompt managementof these conditions, and for evaluative studies of interventionstrategies.     

SUCCESSFUL ENDOSCOPIC CLOSURES OF COLONIC PERFORATIONS REQUIRING ABDOMINAL DECOMPRESSION AFTER ENDOSCOPIC MUCOSAL RESECTION AND ENDOSCOPIC SUBMUCOSAL DISSECTION FOR EARLY COLON CANCER

Endoscopic submucosal dissection (ESD) for colorectal cancer is not widely accepted because of its technical difficulty and the risk of perforation. In addition, the risk of peritonitis cannot be completely eliminated even if a perforation is closed successfully. Reported here are two cases of early colon cancer in which the patients sustained iatrogenic perforations of the ascending colon during conventional endoscopic mucosal resection and of the sigmoid colon during ESD, respectively, requiring abdominal decompression with an 18 G Medicut needle. Both of these perforations were successfully treated by endoscopic clipping. In conclusion, conservative medical management may be possible in patients who have undergone successful closure of colonic perforations using endoscopic clipping. In order to perform immediate endoscopic closure, abdominal decompression has been useful to decrease patient discomfort and colonic lumen collapse. Now, CO₂ insufflation is being used effectively for the prevention of pneumoperitoneum.     

保留后方韧带复合体在胸腰椎骨折治疗中的意义

[目的]探讨保留后方韧带复合体在胸腰椎骨折治疗中的意义。[方法]1998～2002年单一节段胸腰椎爆裂骨折治疗中保留后方韧带复合体44例，同期行胸腰椎爆裂骨折治疗切除后方韧带复合体者35例。两种方法分别有15例（定义为A组）和12例（定义为B组）行2次手术取出内固定物，比较AB两组间2次手术前后腰椎功能JOA评分。[结果]2次手术前腰椎功能JOA评分：A组平均24．5分（19～29分）；B组平均22．8分（19～29分），二者无显著性差异（P〉0．05）。2次手术后JOA评分：A组平均24．8分（20～29分），B组平均17．5分（13～26分）。二组有显著性差异（P〈0．05）。[结论]胸腰椎骨折治疗中保留后方韧带复合体，利于术后腰椎功能恢复。
