心血管疾病基因治疗的基础研究Ⅵ．一种新的体内基因转移方法

将医用缝合线浸泡在质粒ＤＮＡ溶液中，然后缝合在大鼠股四头肌上，可以观察到外源基因在肌肉组织中高效、稳定地表达，其表达量高于磷酸钙共沉淀和ＤＮＡ沉淀块埋植法，较肌肉直接注射法表达量高１０倍左右。     

Arthroscopic capsulorrhaphy formultidirectional instability

Multidirectional shoulder instability is a common affliction and is increasingly recognized as a debilitating condition in young, athletic patients. Most patients with this condition are in their third decade and have a history of macrotrauma or repetitive microtrauma. Complaints range from frank instability to instability with pain, or to pain alone. These patients may display clinical signs of instability, impingement, or both on physical examination. Generalized ligamentous laxity or shoulder laxity alone are usually present. A positive sulcus sign remains the most sensitive clinical test in distinguishing these patients, even though no data is available on the sensitivity or specificity of this examination. The greater majority of patients are successfully treated with an exercise program stressing rotator cuff and scapular stabilizer strengthening. When patients do not respond to conservative treatment, open capsular shift has been recommended to restore joint stability. Early successes with the arthroscopic treatment of anterior shoulder instability have led to the development of similar procedures for the treatment of multidirectional instability. This paper describes an arthroscopic, multiple suture capsulorrhaphy for the treatment of multidirectional shoulder instability, which is a modification of the procedure advocated by Caspari and reviews the 2-year results of the first 19 patients treated.     

丝裂霉素C及可调整缝线在小梁切除术中的应用

目的 观察丝裂霉素C联合可调整缝线在青光眼小梁切除术中应用的效果。方法 我院近3年来小梁切除术98例,术中采用巩膜瓣下放置含丝裂霉素C棉片2～5分钟,然后迅速以平衡盐溶液冲洗,切除2mm×3mm包括小梁在内的深层角巩膜缘组织,并做虹膜根部切除,用10-0尼龙线间断缝合巩膜瓣2～4针后,再于巩膜瓣一侧或两侧作1条或2条型巩膜瓣缝合。形成前房。术后2周、3月、1年及1.5年检查视力、眼压、前房、滤过泡等情况。结果 术后眼压控制良好,Ⅰ、Ⅱ度浅前房发生率低,滤过泡形成良好,43％视力保持不变或改善,炎症反应轻,并发症少。结论 丝裂霉素C可提高小梁切除术后眼压控制率,联合可调整缝线,可有效控制术后滤过水平,减少术后并发症,提高成功率。     

Arthroscopic rotator cuff repair:Indications and technique

Arthroscopic repair of rotator cuff tears is now possible. By using the biomechanical principles of margin convergenceand the balance of force couples, even large cuff defects can be repaired. Suture anchors are particularly suitable for arthroscopic repairs, and a corkscrew anchor design lends itself to a trans-tendon approach     

两脚和四脚快速腭扩张器疗效的比较研究

目的:本研究比较了两脚和四脚腭快速扩张器在打开腭中缝和牙齿扩张的效果.方法:本研究包括30例患者,随机分配在两脚扩张器组和四脚扩张器组,在扩张器戴入前,扩弓结束后和扩张器拆除时,拍摄标准咬合片和采取上颌模型,并对测量数据进行统计分析.结果:研究发现两组间的磨牙尖宽度、磨牙龈宽度、尖牙尖宽度、尖牙龈宽度和中切牙间裂隙间没有统计学差异;在牙弓的周长和腭中缝打开上略有差异.结论:两脚扩张器和四脚扩张器对腭中缝和牙列的作用相同.     

Neuroblastoma-like epidural localization in non-Hodgkin's lymphoma

Summary We report a case of non-Hodgkin's lymphoma with CNS involvement confined to the epidural space causing cranial suture diastasis. Cerebrospinal fluid and bone marrow were normal. Two cases only of cranial epidural lymphoma have been reported in the literature; in both cases, the leptomeninges were also involved but without suture diastasis.     

鞋带式可调整缝线在小梁切除术中的应用

目的评价鞋带式可调整缝线在小梁切除术中作用和效果。方法回顾性分析首次接受小梁切除术的青光眼患者156例205眼,其中无可调整缝线(A组)41眼,行褥式可调整缝线(B组)66眼和行鞋带式可调整缝线者(C组)98眼,对照分析各组术后低眼压、浅前房、脉络膜脱离等并发症的发生情况。结果3组病例术后眼压控制理想;术后浅前房、低眼压发生率C组低于A组和B组,差异均具显著性意义(P<0.05);脉络膜脱离发生率C组低于A组,差异有显著性意义(P<0.05);术后浅前房持续时间C组、B组明显低于A组,差异均有显著性意义(P<0.05)。结论鞋带式可调整缝线在小梁切除术中的效果确切,可增加手术安全性,减少术后早期并发症。     

Bleeding from gastric ulcer halted by laparoscopic suture ligation

In a 48-year-old Japanese man there was an uncontrollable and recurrent bleeding from a gastric ulcer and laparoscopic surgery was done. Two cannulae were placed in the gastric cavity through the abdominal wall and suture ligation of the bleeding vessel at the posterior wall of the stomach was done under videovisual control with endoscopic guidance. The bleeding ceased, complications were nil, and he remains well.This article reports on surgery done to repair uncontrollable, recurrent bleeding from a gastric ulcer. Two cannulae were placed in the gastric cavity through the abdominal wall and suture of the vessel at the posterior wall of the stomach was done with videovisual control and endoscopic guidance. This approach is concluded to have supplied minimal-access surgery, cost effectiveness, early discharge, less pain, and doctor-patient satisfaction.     

胃肠粘膜外翻缝合加浆肌层缝合的研究

胃肠、胆肠及肠肠吻合,采用粘膜外翻缝合外加浆肌层缝合256例,与同期采用Albert-Lambert缝合318例对比。结果:外翻缝合育操作简单、顺手、省时、线头残留少等优点。     

术中放置鼻胆管在胆总管切开取石探查后一期缝合的研究

目的探讨术中放置鼻胆管在胆总管切开取石探查后一期缝合术与传统胆总管探查T管引流术疗效的对比。方法对我院2005年6月至2007年3月126例胆石症患者行手术治疗进行回顾性分析,其中65例术中采用T管引流（T管组）,61例采用鼻胆管引流（鼻胆管组）,两组术后均经胆道造影证实通畅。结果鼻胆管组与T管组比较,后者术后拔管及胆汁引流时间明显缩短,（P〈0.05）;术后住院天数明显缩短（P〈0.05）;术后与引流相关的并发症发生率低（P〈0.05）。结论胆道外科术后采用鼻胆管引流能够缩短患者住院时间,可避免胆汁大量丢失,并发症少,避免了长期带T管的痛苦,是一种较为理想的引流方式。
