氯沙坦对维持性血透患者心血管保护作用的临床观察

目的 :观察氯沙坦对行维持性血透治疗的慢性肾功能衰竭 (CRF)患者心血管保护作用。方法 :6 0例维持性血透患者 (血肌酐≥ 70 0 μmol·L- 1 ) ,治疗组 (给予氯沙坦 5 0～ 10 0mg·d- 1 )及对照组 (给予非血管紧张素受体拮抗剂和非ACEI类降压药 )各 30例 ,记录用药前后各组患者血压 ,运用多普勒组织成像 (DTI)技术观察用药前后两组患者二尖瓣环峰值收缩速度 (VS)、收缩时间速度积分 (TVIS)、舒张早期速度 (VE)、舒张晚期速度 (VA)、VE VA 比值。结果 :治疗组及对照组患者治疗后血压均明显下降 ,二尖瓣环VS、TVIS、VE、VE VA ,则均明显上升 ;治疗组与对照组血压分别在治疗前、后相比并无明显差异 ;治疗前两组间二尖瓣环VS、TVIS、VE、VE VA 并无显著性差异 ,但在治疗12个月后 ,治疗组二尖瓣环VS、TVIS、VE、VE VA 则明显高于对照组。结论 :氯沙坦对行持续性血透的CRF患者具有良好的心脏保护作用 ,可有效改善其心功能 ,且不依赖于其降压作用     

胸部外伤致食管破裂的X线诊断2例报告

胸部外伤性食管破裂少见,易误诊。现将我院经X线诊断证实2例报告如下。 例1.患者男,20岁。5天前酒后骑摩托车与汽车相撞,当即昏迷,送当地医院诊治。当日患者饮水后即呕吐,为胃内容物。次日出现胸闷,呼吸困难,烦躁不安。胸透见两侧胸膜腔大量液气胸,钡餐检查见食管破裂。遂予以胸腔闭式引流转入我院。外科情况:胸廓饱满,双肺叩实,呼吸音减低,经两侧胸膜腔引流出大量带恶臭味脓液。X线检查:鉴于患者一般情况较差,予以半卧位透视,见两侧液气胸,右肺组织被压缩约10％。左侧液气胸伴多发性包裹性液气胸,肺组织压缩约40％。随即仰卧位服70％泛影葡胺100ml,见造影剂迅速经食管下段破裂处进入双侧胸膜腔,确诊为食管下段破裂,虽经积极抗感染、深静脉高营养,输血、空肠造瘘及各种支持疗法等,但因患者不配合治疗,多次趁人不备,自拔引流管及多次饮水,终因中毒性休克、呼吸循环衰竭死亡。     

带蒂薄皮瓣在严重手外伤修复中的应用

我科自１９９１年以来采用带蒂薄皮瓣急诊修复严重手外伤７例，皮瓣供区位于左、右侧腹壁及腹股沟。皮瓣最大面积为１８ｃｍ×７ｃｍ，最小面积为１１．５ｃｍ×６ｃｍ。除１例火药炸伤在术后１３天皮瓣断蒂外，其余均在术后７天断蒂。皮瓣全部一期成活。手外形和功能恢复较好。对薄皮瓣的优点，血供机理及术中、术后应注意的问题进行了讨论。     

变异型心绞痛的发作诱因和合并症

本文报告3例饮酒诱发变异型心绞痛者,2例发展为急性心肌梗塞,1例合并Ⅲ度房室传导阻滞.另3例无诱因的典型变异型心绞痛发作皆无合并症.上述结果提示:饮酒是变异型心绞痛发作的最常见诱因,与无诱因者相比,予后更为严重.因此,有冠状动脉痉挛倾向者如变异型心绞痛,不稳定型心绞痛,卧位或夜间发作的心绞痛等,应避免饮酒.     

寰枢椎椎弓根钉固定治疗伸直型齿状突骨折合并寰枢关节半脱位

Objective To explore the clinical outcome of atlantoaxial pedicle screw instrument in treatment of extension-type odontoid fracture combined with aflantoaxial subluxation. Methods From December 2002 to December 2006, seven patients with extension-type odontoid fracture combined with at-lantoaxial subluxation were reduced and fixed with atlantoaxial pedicle screw instrument of Vertex system under general anesthesia. There were five males and two females, at mean age of 39.2 years (range 21-59 years). All odontoid fractures were fresh type Aderson Ⅱ. JOA scores of spinal core function was 8.6-14.9 (average 10.7) preoperatively. The X-ray examination, CT scanning and skull traction were performed in all patients preoperatively. Results There found no severe complications such as injuries of vertebral artery, nerve root and spinal cord postoperatively. All patients obtained complete reduction and healing of the fracture and dislocation. The mean off-bed time was four days (3-6 days) after opera-tion. A follow-up for 12-36 months (average 22 months) in all patients showed that the clinical symptom was improved significantly six months postoperatively and that all screws were in proper position verified by X-ray and CT scanning. All patients obtained solid bony union on radiographs, with no loosing or breakage of instrument. The postoperative JOA scores was 13.5-16.9 (average 15.8). Conclusions Allantoaxial pedicle screw fixation has advantages of intraoperative reduction, reliable fixation and high fusion rate and can be used as an effective method for extension-type odontoid fracture combined with at-lantoaxial subluxation.
