Genetic distinctions between autoimmune hepatitis in Italy and North America

引用

World Journal of Gastroenterology 2005年第12期11卷 1862-1866页

AIM: Our goals were to analyze the known genetic predispositions for autoimmune hepatitis (AIH) in AIH Italian population and to compare them with North American ***: Human leukocyte antigens (HLA) B8, C7, DR3,DR4, DR7, DR11, DR13, DQ2 and the B8-DR3-DQ2phenotype were determined by microlymphocytotoxicity and polymerase chain reaction in 74 Italian patients (57with type 1 and 17 with type 2 AIH) and 149 North American patients with type 1 AIH, and in adequate ***: B8-DR3-DQ2 occurred more frequently in Italian patients with type 1 AIH than in Italian controls (30% vs 7%, P＜0.0001), but less frequently than in North American counterparts (30% vs48%, P = 0.02). DR4 occurred less frequently in Italian patients with type 1 AIH (23% vs43%,P= 0.01) and in controls (16% vs34%, P= 0.0003) than in North American counterparts. No differences were found in alleles' frequency between type 1 and type 2Italian AIH patients. DR11 had a frequency lower in type 1 Italian AIH patients than controls (17% vs35%, P= 0.01).CONCLUSION: HLA DR4 is not associated with AIH in Italy. The known HLA risk factors for ATH occur similarly in Italian patients with type 1 and type 2 AIH, and they are less frequent than in North American patients. B8-DR3-DQ2 is the predominant phenotype of type 1 AIH also in Italy, and HLA DR11 may be a regionally distinctive protective factor against type 1 AIH.

世界核心医学期刊文摘（心脏病学分册） 2006年第8期2卷 44-45页

作者： mantovani V. Mariscalco G. Leva C. 杜媛 Department of Cardiac Surgery Ospedale diCircolo-Fondazione Macchi Università dell'Insubria Viale Borri 57 21100Varese Italy

Objectives: To review our experience of surgical repair of postinfarction ventricular septal defect(VSD). Methods: In the period 1983-2002, 50 patients underwent repair of VSD. Mean age was 66 years, male sex 52% . Infarct location was anterior in 60% and posterior in 40% of cases. Median interval between rupture and surgery was 2 days. Preoperative intra-aortic balloon counterpulsation was employed in 56% ; a coronary angiogram was performed in 98% of cases. A patch repair technique was used in 90% of cases. Coronary bypass grafting was associated in 50% of patients. Results: Mean aortic clamp time was 101± 31 min. Global operative mortality was 36% , respectively 26.7% in anterior and 50% in posterior location(p=ns). Emergency operation and interval from rupture to surgery less than 3 days were univariate predictor of early mortality. Five years survival excluding operative deaths was 76% . Conclusions: The surgical repair of post-infarction VSD entails a high operative mortality; different techniques were employed with similar results. Emergency operation is associated with a worse short-term prognosis; long-term survival is acceptable.

Sauris水库是一个水力发电水域，在其下游方向用高136米的双拱形混凝土水坝截流。水坝稳固地建造在坚硬的岩石上（Dolomia dello Schlern），但是，部分坝体处于早三叠纪粘土层上部——尤其是斜坡下部区域露出地面的早三叠纪粘土层，由于汇水盆地的蓄水增大了坝体滑动的可能。近年来，在“La Maina”滑坡区域约10万平方米滑坡体表面上已出现多个裂缝，滑坡体体积约150万立方米。目前假定的不稳定区域的发育需要特别关注，如该水库所处的滑坡坡脚区域。在地方全民保护管理委员会的领导下，为了了解交通基础设施、一些建筑物和水库存在的风险，以及将来采取应急措施稳定斜坡，开发了一种模拟斜坡虚拟时间条件的数值模型。应立即建立一种由4个测斜仪、3个弦式伸缩仪和10个GPS基准点组成的监测系统，来监测滑坡的表面位移和深层位移。常利用收集的数据，依据地质和形态学开展数值模拟。通过比较模型与斜坡运动的形态学依据，检验模拟结果的可靠性。按照该数值模型提供的资料设计和实施缓解方案。

The cultivation of the marine species of shrimp Litopenaeus vannamei has emerged as one of the segments that best develop in the Brazilian aquaculture, representing the agribusiness that grew the most in recent years. Regarding the economic importance of the farming of this species in Brazil, further studies on genetic improvement were conducted. A F2 segregating population consisting of 192 samples for each G1 and G2 families, from crossing inbred lines was used for the studies performed in the present work. The genetic linkage analysis was based on polymorphic markers derived from nine AFLP (Amplified Fragment Length Polymorphism) primers. Fourteen genetic linkage groups including 103 segregating polymorphic markers were constructed covering350 cMfor G1 and four genetic linkage groups including 59 markers were constructed covering300 cMfor G2. Simple marker analyses were performed among individuals evaluated phenotypically, finding markers linked to genes that may be potentially important and useful to assess characteristics of economic importance for traits related to weight and the disease IMN (idiopathic muscle necrosis). The statistical model including markers explained major proportion of phenotypic characteristic weight in relation to disease incidence IMN.
