伊贝沙坦对老年高血压患者24h动态脉压及血浆内皮素的影响

高血压病是危害中老年人健康最常见疾病之一，积极治疗高血压可减少患心肌梗死、脑卒中、心肾功能不全等并发症的发生。作自2003年5月至2005年4月分析口服伊贝沙坦对84例老年高血压患的24h脉压和血浆内皮素水平的影响，探讨伊贝沙坦对老年高血压患的治疗意义。     

500例晚期孕妇血浆凝血项目的统计分析

晚期孕妇血液的凝血状态．对预测分娩过程中及产后大出血导致急性DIC和血栓栓塞性疾病有重要意义。而检测凝血酶原时间（PT）、凝亦酶时间（TTT）、活化部分凝血酶原时间（APTT）和纤维蛋白（FIB）是判断机体止血和凝血变化与筛查凝血性疾病的重要指标。     

荧光定量聚合酶链反应检测库存血浆HBV-DNA及HCV-RNA

目的 调查库存血中HBV-DNA及HCV-RNA的阳性率。方法 采用荧光定量聚合酶链反应(FQ-PCR)法,对合格库存血浆进行微量汇集池标本(10份×50μl汇集)中的HBV-DNA和HCV-RNA测定,再对阳性汇集池中的标本进行单份检测。结果 250份(分25个汇集池)受检血浆中HCV-RNA阳性1份(0.4％),HBV-DNA阳性2份(0.8％)。结论 荧光定量PCR检测微量血浆汇集池标本法筛查血液病毒核酸是提高输血安全性的一种先进方法。     

全髋关节置换术治疗强直性脊柱炎致髋关节强直的疗效及康复锻炼的意义

Objective To investigate the clinical effects of total hip arthroplasty (THA) for bony ankylosis in patients with ankylosing spondylitis and the significance of postoperative rehabilitation. Meth-ods From October 1998 to May 2007, 28 patients (46 hips) suffered from ankylosing spondylitis with hip bony ankylosis underwent THA. There were 27 males, 1 female, with the mean age of 38.9 years (range 22 to 58 years). Posterior lateral hip incision was performed in 34 hips, and modified anterior lateral combined with lateral hip incision in 12 hips. Forty hips applied cementless THA and 6 hips applied mixed THA. Har-ris scores, VAS scores and total hip range of motion in all patients were compared pre-and postoperatively to evaluate the clinical effects. Results All patients were followed up from 10 months to 64 months, with the mean time of 38.2 months. No paralysis, decubitus, and lung infection were found. Joint dislocation hap-pened in 1 case 2 weeks after operation, and was cured with close reduction. Heterotopic bone formation with Brooker Ⅰ was found in 6 hips and Brooker Ⅱ in 2 hips. Harris score increased from 28.3±10.3 preop-eratively to 82.7±7.6 postoperatively. VAS score changed from 3.5±1.4 preoperatively to 3.8±1.8 postopera-tively, and no significance was found. The hip movement range increased from 15.6°±9.3° preoperatively to 133.7°±17.6° postoperatively. Bony ankylosis in all patients disappeared and the hip function improved sig-nificantly after operation. Conclusion THA is the optimal method to treat the ankylosing spondylitis with hip bony ankylosis. Early rehabilitation is necessary to improve hip function.     

神经肽Y在中枢神经系统疾病患儿血浆和脑脊液中的变化与意义

近年来神经生物学领域的一个重大突破是神经肽的研究取得的进展。神经肽Y（neuropeptide Y，NPY）是新发现的一种神经肽，具有调节血压、生物节律和内分泌功能等多种生物效应。有关小儿中枢神经系统疾病患儿脑脊液中NPY的变化研究尚少。为探讨NPY在中枢神经系统疾病患儿脑脊液中的变化与临床意义，笔者对26例中枢神经系统疾病患儿不同时期的脑脊液和血浆NPY水平进行了研究。     

腹腔镜辅助下的腹主动脉瘤手术与传统手术的对比

腹主动脉瘤传统手术采用开腹人工血管置换，手术创伤大，术后患者恢复慢。随着腹腔镜在腹部外科应用的进展，传统腹主动脉瘤手术已经可以被腹腔镜辅助下完成人工血管置换所替代。此外，腹主动脉瘤腔内隔绝术部分并发症也能用腹腔镜辅助方式得到解决，现就该技术的操作、效果以及与传统手术的比较作一综述。     

移位的股骨颈骨折手术方法选择与疗效分析

目的比较分析加压空心钉内固定与人工关节置换术治疗中老年移位的股骨颈骨折的适应证与临床疗效。方法1994～2004年分别使用加压空心钉内固定加带血管或肌骨瓣植入术(内固定组43例)和人工髋关节置换术(置换组46例)治疗中老年移位的股骨颈骨折共89例,随访并比较分析疗效及适应证。结果内固定组平均住院天数及手术时间较短,出血量少,与置换组比较差异有显著性意义(P＜0．05)；全部患者获得24～56个月(平均48．5个月)的随访；关节功能评价采用Harris评分,内固定组从术前的平均45．2分提高到术后79．6分,置换组从术前的平均45．2分提高到术后90．4分,两组术后功能差异有显著性意义(P＜0．05)。结论GardenⅢ型的新鲜股骨颈骨折患者(＜65岁)宜首选加压空心钉内固定加带血管或肌骨瓣植入术；年龄相对较大(＞65岁)的GardenⅢ、Ⅳ型患者宜首选人工髋关节置换术。     

18例主动脉置换术后监测治疗的体会

主动脉夹层（aortic dissection,AD）是心血管系统的急症,病情变化快,死亡率极高,未就诊的患者50%于2 d内死亡,70%于7 d内死亡.除内科保守治疗外,外科手术是最主要的治疗手段,关于AD的术后监测治疗资料报道较少,现将我院18例患者术后治疗体会进行总结.
