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.

心脏按压有效的指征是什么？

答：心脏按压有效的指征有七个：（1）按压时能摸到大动脉搏动，收缩压大于8．0kPa；（2）病人面色、口唇、甲床及皮肤色泽由灰白转红润；（3）散大的瞳孔又缩小；（4）有呼吸改善或出现自主呼吸；（5）昏迷变浅或出现反射挣扎；（6）有尿液排出；（7）心电图形改善。只要前两项指标出现，就应坚持按压心脏。

四氧嘧啶诱发糖尿病大鼠血管紧张素的变化

实验观察了四氧嘧啶诱发糖尿病大鼠连续饲养１１０ｄ后体内肾素一血管紧张素系统的变化。结果表明，血浆和心脏的血管紧张素Ⅱ含量无明显变化，而肾脏的ＡｎｇⅡ含量却明显低于正常对照组。另外，心脏的心钠素（ＡＮＰ）含量在糖尿病大鼠与正常对照组之间无差别，血中的糖化血红蛋白含量基本无变化。上述结果表明，糖尿病大鼠早期心脏可能无明显损伤，而肾脏的肾素一血管紧张素系统活性降低。     

美托洛尔对老年人高血压病左室肥厚的逆转

探索美托洛尔对老年高血压病左室肥厚有否逆转作用，方法：高血压ＩＩ期病人３８例采用美托洛尔２５￣５０ｍｇ，ｐｏ，ｔｉｄ，共１０￣１６ｍｏ。相似病例３０例（男性２３例，女性７例；年龄６６±６ａ）采用氢氯噻嗪２５￣５０ｍｇ，ｐｏ加螺内酯２０￣４０ｍｇ，ｐｏ，ｔｉｄ，共１１０￣１６ｍｏ作为对照，结果：美托洛尔组治疗后左室后壁厚度、室间隔厚度、舒张期左室内径、左室心肌重量指数均显下降（Ｐ〈０．０１），小轴
