目的:用Norwood术治疗左心发育不全综合征,常在术后发生神经功能缺损。由于深低温停循环技术与不良神经后果相关,所以采用区域性低流量脑灌注来减少术中脑缺血时间。为了评估这种技术对脑缺血的影响,作者在一组患儿采用区域性脑灌注的Norwood手术前后对其进行了脑磁共振成像检查。方法:在Norwood术前和术后(中位期为9.5d)对22例患有左心发育不全综合征的足月新生儿进行了脑磁共振成像检查。用术前、术中和术后危险因素对结果进行比较,以确认神经损伤的预测因素。结果:术前磁共振成像(n=22)发现23%的患者有缺血性病变。术后磁共振成像(n=15)发现73%的患者出现新发缺血性病变或原有缺血性病变加重,脑室周围白质软化和局灶缺血性病变的出现极为普遍。术后脑低血氧时间延长(180min)与术后磁共振成像检测到的新发缺血或原有缺血加重相关(P=0.029)。[第一段]

由于许多兽药生产企业重新考虑本行业的现状和将来,兽药的研究开发投资最近变得缓慢下来。目前兽药研究与生产面临的困难是:销售不景气,研究费用上涨;为满足各种法令要求要支出高额费用;消费者协会对许多新型药品反对等。其它主要的困难是30年前许多兽药新产品是与人用药物研究相联系开发的,现在,大部分兽药开发的全部费用要由兽药生产企业负担。尽管困难重重,还是有很多公司热衷于制订开发研究计划。

The purpose of the study was to examine long-term outcome after traditional surgical treatment of corrected transposition of the great arteries to prov.de a b.sis for comparison with new procedures, such as the doub.e-switch or Senning-Rastelli procedures. Patient-and procedure-related v.riab.es in 123 patients with corrected transposition and 2 functional v.ntricles operated on b.tween 1963 and 1996 were analyzed. Patients with intracardiac procedures underwent either a traditional 2-v.ntricle repair or a Fontan procedure. The 1-, 5-, 10-, and 15-year surv.v.ls after the operation were 84%, 75%, 68%, and 61%, respectiv.ly. Patients requiring tricuspid v.lv. replacement(27 patients)at any time during follow-up had a significantly worse outcome(P b.st outcome was seen in patients undergoing the Fontan procedure(17 patients, 0 deaths). Right v.ntricular end-diastolic pressure of greater than 17 mm Hg b.fore the operation(P b.ock after the operation(P=.001), sub.alv.lar pulmonary stenosis(P=. 013), Eb.tein malformation of the tricuspid v.lv.(P=.025), and preoperativ. systemic(right)v.ntricular dysfunction(P=. 041)were identified as risk factors for death at any time b. means of univ.riate analysis. Eb.tein malformation of the tricuspid v.lv.(P=.036; hazard ratio, 1.5)was identified as a risk factor for death b. multiv.riate analysis. The long-term outcome of patients with corrected transposition after a classic surgical approach is unsatisfactory. The poorest outcome was seen in patients who required tricuspid v.lv. replacement either at their initial operation or later during follow-up. Alternativ. surgical approaches, such as the doub.e-switch, Senning-Rastelli, or Fontan procedures, are likely to hav. b.tter long-term results, especially in the highest risk groups.

Strain dev.lopment along radial direction was continuously determined b. D-200 Linear v.riab.e Differential Transformers (L.v.D.T). When a wood specimen was put into water and b.gin to swell from ab.olute dry moisture content to the maximum. Experiment results show that the differences of swelling with soaking time b.tween untreated and treated wood specimens due to uptaking water. It would also giv. an indication to the effectiv.ness of v.rious chemicals on the dimensional stab.lity of modified wood. ASE of modified wood samples with SA-EP, EP and SA were found to b. b.tter than MA-AGE. SA-EP had got the b.st effetiv.ncss on dimensional stab.lity in reducing the swelling.

b.ckground: The purpose of this study was to assess the ov.rall short-term outcome of stent-graft repair for thoracic aortic disease in France b.tween June 1999 and May 2001. Methods: This retrospectiv. study was designed b. the French National Health Insurance Fund for Salaried Workers. To ensure ob.ectiv.ty, data were retriev.d at each center and checked b. a team of medical adv.sors. Results: b.tween June 1999 and May 2001, a total of 166 stent-graft repairs for thoracic aortic disease were performed in 166 patients, mainly b. surgeons in the operating room(88% ). Patients were classified according to the American Society of Anesthesiologists as status I or II in 24% of cases, status III in 56% , and status Iv.or v.in 20% . The diameter of the thoracic aneurysm was less than 50 mm in 17% of cases. Sev.nteen patients(10% ) died during the first 3 months, including 8 within the first 30 days after the procedure. A total of 49 complications were noted in 34 patients(20.5% ). Endoleaks occurred in 27 patients(16.3% ), including 8 that necessitated further treatment. Other stent-related complications included rupture(n=3), aortoesophageal or tracheal fistula(n=3), paraplegia(n=6), stent migration(n=2), v.sceral emb.lism(n=5), and cereb.al emb.lism(n=2). There were 14 deliv.ry-related complications(8% ) at the catheterization site. Non-stent- related complications occurred in 14(8% ). Conclusions: This nationwide study demonstrates that stent-graft repair for thoracic aortic disease can b. performed with acceptab.e postoperativ. morb.dity. Howev.r, it is not a risk-free procedure and should continue to b. used in an inv.stigativ. setting.
