18例气胸复张过程中并发症的抢救

目的 分析自发性气胸在肺复张过程中的并发症，以提高诊断与抢救水平。方法 对18例气胸在复张过程中出现的并发症、抢救措施及预后进行分析。结果 肺复张过程中常见并发症有3种，即闭合性生气胸变为张力性气胸，出现胸膜反应及复张性肺水肿（RPE），前2种预后良好，均痊愈出院，RPE有2例（50％）死亡。结论 对张力性气胸与RPE应争分夺秒进行抢救。     

Transplantation of an eight-organ multivisceraI graft in a patient with frozen abdomen after complicated Crohn's disease

To report an extended multivisceral transplantation (MVTx) including right kidney and ascending colon in a patient with complicated Crohn's disease (CD). A 36-year old female suffering from short bowel syndrome and frozen abdomen due to fistulizing CD after multiple abdominal operations underwent MVTx of eight organs including stomach, pancreatoduodenal complex, liver, intestine, ascending colon, right kidney, right adrenal gland, and greater omentum in November 2003. Immunosuppression consisted of alemtuzumab, tacrolimus and steroids. The patient was off parenteral nutrition by postoperative wk 3. She experienced one episode of pneumonia. The patient recovered completely and discharged 2.5 mo and was doing well 30 mo after MVTx. This is one of the very rare cases in which a complete mulitivisceral graft of eight abdominal organs was transplanted orthotopically.     

单纯碎裂电位指导心房颤动消融的初步临床观察

Objective To evaluate the feasibility of mdiofrequency catheter ablation of atrial fibrilla-tion (AF) guided by complex fractionated atrial electrograms (CFAEs). Methods Twenty-two patients with drug refractory and symptomatic AF(16 paroxysmal, 6 persisten) were enrolled. Using Carto, the left atrial or biatrial replica was created during spontaneous or induced AF, and areas associated with CFAEs were identi-fied. Radiofrequency ablation at the site with CFAEs was performed and the end points were to eliminate CFAEs or convert to sinus rhythm. Results Thirteen patients(59%)were converted to sinus rhythm, (7 cases conver-ted directly to sinus rhythm, and 6 via the intermediate atrial tachycardia(AT) or atrial flutter (AFL). The re-maining nine patients required cardioversion with D. C. shock or drug. Repeat ablation was performed in 6 pa-tients (5 AT/AFL, 1 paroxysmal AF). During(10.9 ±4.8) months follow-up, 16 patients (73%) were free of arrhythmia and symptoms. CFAEs were most commonly found along the left interatrial septum, pulmonary veins, left atrial roof. CFAEs ablation prolonged AFCL[(157 ± 18) ms vs (211 ± 32) ms, P < 0.05]. Only one patient had pericardial tamponade that required pericardiocentesis. Conclusion Radiofrequeney catheter abla-tion of atrial fibrillation (AF) guided by CFAEs is safe and effective.

小凹蛋白1在动脉粥样硬化中的作用

小凹是细胞表面胞膜穴样内陷,小凹蛋白为小凹的主要组成成分。其中小凹蛋白1在单核/巨噬细胞、内皮细胞和平滑肌细胞中均有表达,在动脉粥样硬化形成发展过程中发挥重要而广泛的作用。     

胰源性门脉高压症一例

患者女,49岁,因反复呕血黑便1个月入院.入院前1个月,患者无明显诱因出现呕血、黑便,呕吐物为咖啡样物,每次约50 ml,大便为黑色稀糊状,每次约150 g,每天3～4次,在院外予抑酸等治疗,可好转,但症状反复发生,1周前再次呕血伴黑便,遂来我院治疗.     

肝细胞核因子-κB异常激活与肝细胞癌变

核因子-κB（nuclear factor-κB，NF-κB）是具有和某些基因上启动子区固定核苷酸序列结合而启动该基因转录的蛋白质。NF-κB是具有多向性调节作用的核转录因子，可调控多种基因（免疫、炎症反应、病毒和原癌基因）的转录表达。激活的NF-κB参与癌症的启动、发生及发展过程，在炎症性相关的肝癌（HCC）发生发展中呈高表达，在肝细胞炎症与癌变间起桥梁作用，其中包括肝脏免疫炎症反应相关基因、肝炎病毒相关基因和原癌基因的转录表达。在肝癌组织中异常激活，可抑制细胞凋亡，促进肝细胞存活，与肝癌的发生发展密切相关。     

1996—2001年在家实施胃肠外营养的调查研究

目的:自1970年以来,丹麦就开始对肠衰竭患者推行在家实施胃肠外营养(H PN)。该研究设计为一个数据来源可靠的系列化队列研究,回顾性调查了1996—2000年底丹麦全国的H PN患者资料,包括发病率、患病率、患者特征和H PN治疗的并发症等。材料与方法:选取接受H PN治疗的患者202例(女性115例,男性87例),其中34%为炎症性肠病导致的短肠综合征,26%为癌症患者,22%为外科手术并发症,19%为其他原因,共使用410(导管·年)。结果:截止2000年底,全丹麦H PN流行率为19.2/106人,平均发生率为5.0/106(人·年),与导管相关的菌血症和血栓发生率分别为0.48/…

抑郁症与口腔疾病

随着现代社会活动节奏加快、竞争加剧 ,一部分人出现社会适应不良 ,并受到抑郁症的困扰。患者心境抑郁 ,伴有一系列躯体不适症状 ,生活质量和社会职业能力显著下降 ,伴高自杀率。 2 0 0 0年ＷＨＯ将它列为全球导致残障和早逝的第四位原因 ,并预测 2 0 2 0年抑郁症将成为仅次于缺血性心脏病的第二大疾病[1] 。抑郁症患者易发生多种口腔疾病 ,如猛性龋、牙周病及慢性面部疼痛 (包括颞下颌关节紊乱综合征和灼口综合征等 )。病人可能在尚未意识到患抑郁症之前先到口腔科就诊。因此 ,口腔医生有必要了解抑郁症的一般临床表现、病理生理、抗抑郁治…
