升主动脉成形术中期效果分析

Objective Reduction ascending aortoplasty is an alternative procdure to the replacement of the ascending aorts in case of ascending aorta dilation. However,its applicabikity is still under debate.This retrospective study was designed to evaluuate the midterm follow-up of unsupported ascending reduction aortoplasty for of the ascending aorta in petients with aortic valve dis- ease.Methods From October ,1996 to April,2007, a total of 54 patients with aortic valve disease and dilatation of the ascending aorta underwent unsupported reduction aortoplasty in combination with aortic valve replacement at our institution The diameter of the ascending aorta was measyred before and early after sugery and then later between 13 and 96 menths [mean (23 ±16)months] posto- perativeiy using echocardiography.Results Two patients were dead with thean overall perioperative mortality rate was of 3.7%. The reduction aortoplasty decreased the diameter of the aorta from (45.77±6.02) mm p～eope～afive]y to (34.67 ～4.81) mm early after surgery (P<0.01). During follow-up, the diameter d aorta increased from (34.67±4.81) mm early after surgery to (37.65± 6.35) mm after a mean follow-up of (23±16) months (P<0.01), including the diameters are greater than > 45 mm within 5 pa- tients. Aortic stenosis and an early postoperative diameter greater than 40 mm m'e independent risk factors for redilatation. Conchusion Because of the unsatisfied midterm follow-up redilation of unsupported reduction aortoplasty for dilation of the ascending aorta with aortic valve disease, this group of patients needs continued intimate fallow-up or even reoperation. The patients of stenosis is the surtable indication for RAA, and it is necessary to reduce the diameter of aorta to be lees than 40 mm to prevent redilation.     

活血止痛贴膏的制备

<正>活血止痛贴膏系根据传统验方研制而成,具有活血化瘀、消肿止痛的功效,临床用于跌打损伤、伤筋骨折、局部肿痛等症。原剂型系外用散剂,经鸡蛋清调和后敷于患处,疗效较佳,但患者使用较为不便。笔者对其工艺作一改进,采用巴布剂贴膏剂型,其基质的性能是决定贴膏质量优劣的重要因素,故选择以明胶∶羧甲基纤维素钠(CMC-NA)∶聚乙烯吡咯烷

罕见特应性湿疹案

Monika,女,44岁,丹麦人,2003年9月10日初诊.自诉约1岁时全身皮肤起红色痒疹,20岁后,瘙痒不断加重,皮损日益加重,冬春季尤甚,夏季稍缓解.月经期全身皮肤瘙痒加重,皮肤伴有发冷发热感.近2年来,急性发作时,红疹处皮肤可见淡黄色液体渗出,结痂呈鳞片状,皮肤干燥、皲裂,关节处皮肤较明显.当地医院已确诊为特应性湿疹,曾用激素治疗,症状有改善,但停药后即刻复发加重.既住有多年"支气管哮喘"病史.

介绍一种沥干砂芯滤器内母液的方法吴瑞英谢碧玉（武警福建省总队医院福州３５００１９）不少医院生产大输液采用不锈钢砂芯滤器进行脱炭。每次生产完毕，滤器内总残留不少母液。如不进行处理是一种大的浪费，而且对溶液的稀释和含量的准确性带来困难。为此，我们在砂芯滤...     

大肠癌术后早期肠梗阻的临床特点和治疗

目的：探讨大肠癌术后早期肠梗阻的诊断与治疗。方法：回顾分析在肠癌手术412例术后早期肠梗阻29例的临床资料。结果：20例经手术探查发现以机械性梗阻占多数（18/20)，手术治愈18例；死亡2例，死亡原因均为延误手术时机造成；非手术治愈9例。结论：大肠癌术后早期肠梗阻虽有梗阻症状，但由于术后诸多因素的影响，大多缺乏典型机械性肠梗阻的临床表现。处理中先进行适当时间的非手术治疗，无缓解者再手术。     

一种新的五步蛇蛇毒类凝血酶Cdna的克隆和序列分析

目的：克隆出五步蛇的类凝血酶cDNA，为研究其结构和功能的关系。并为下一步基因表达开发抗血栓药物提供依据和基础。方法：从五步蛇蛇腺中提取了总RNA，通过反转录合成第一链cDNA，经PCR扩增出五步蛇毒腺中类凝血酶TLE1的cDNA片段，并将其连接到质粒载体扩增，然后进行DNA测序。结果：成功克隆出一种新的五步蛇类凝血酶的cDNA片段。此片段全长794bp，包括编码部分的全长为777bp。推导其编码的蛋白质序列为258个氨基酸，其中包括18个氨基酸的信号肽，6个氨基权的前肽和234个氨基酸的成熟氨基酸顺序。TLE1成熟肽与其它蛇毒类凝血酶相比，蛋白质一级结构具有较高的同源性。结论：从五步蛇中成功克隆出一 种新的类凝血酶cDNA，并确定了它的DNA顺序。     

带状疱疹早期诊断的体会

带状疱疹为常见病、多发病,典型病例不难诊断,但在疾病早期或临床表现不典型常可导致误诊。1991～1992年,我们诊治7例带状疱疹患者,早期均被误诊。现报道如下。 1 临床资料 年龄 性别 主要表现 初诊诊断 出疹部位 34 男 发热,乏力,感冒,病毒性 右肋部纳差, 右肋部 肝炎 疼痛 69 男 头痛,全身乏力 脑血管痉挛,右侧额顶部 脑动脉硬化
