1我国部分地区丙型肝炎病毒基因分型研究显示文摘目的 研究中国丙型肝炎病毒 (HCV)基因型分布。方法 应用AmplicorPCR试剂盒检测北京、青岛、固安和周口等地 2 7例抗 HCV阳性的单采浆供血员和 36例慢性丙型肝炎病人血清HCVRNA ,并对其中 36例HCVRNA阳性者用INNO LiPATM HCVⅡ试剂盒进行HCV基因分型。结果 抗 HCV阳性的单采浆供血员和慢性丙型肝炎病人HCVRNA检出率分别为 48.15 % (13/ 2 7)和 6 9.44 % (2 5 / 36 ) ,平均为 6 0 .32 % (38/ 6 3)。对 13例HCVRNA阳性的单采浆供血员和 2 3例慢性丙型肝炎病人HCV基因分型结果表明 ,2 9例 (80 .5 5 % )为 1b型 ,5例 (13.89% )为 2型 ,另 2例(5 .5 6 % )不能被分型。结论 上述调查地区流行的HCV基因型以庄辉 Tracy L 崔怡辉 凌斌华 张玲霞 Bowden S 2001中华流行病学杂志2001,22,2:29

3Endothelin-1 activation in pediatric patients undergoing surgical coarctation of the aorta repair显示文摘AIM To determine endothelin-1(ET-1)concentration before and after surgical coarctectomy and evaluate its association with left ventricular geometric change.METHODSA prospective,cohort study of 24 patients aged 2 d to 10years with coarctation of the aorta undergoing surgical repair.A sub-cohort of patients with age<1 mo was classified as'neonates'.Echocardiograms were performed just prior to surgery and in the immediate post-op period to assess left ventricle mass index and relative wall thickness(RWT).Plasma ET-1 levels were assessed at both time points.Association between ET-1 levels and ventricular remodeling was assessed.RESULTSPatients<1 year demonstrated higher pre-op ET-1 than post-op(2.8 pg/m L vs 1.9 pg/m L,P=0.02).Conversely,patients>1 year had no change in ET-1 concentration before and after surgery(1.1 vs 1.4,NS).Pre-op,patients<1 year demonstrated significantly higher ET-1 than older children(2.8 vs 1.1,P=0.001).Post-op there was no difference between the age groups(1.9 vs 1.4,NS).Neither RWT nor left ventricle mass index(LVMI)varied from pre-op to post-op.The subset of neonates showed a strong positive correlation between pre-op ET-1 and RWT(r=0.92,P=0.001).Patients with ET-1>2 pg/m L preop demonstrated higher LVMI(65.7 g/m^(2.7) vs 38.5 g/m^(2.7),P=0.004)and a trend towards higher RWT(45%vs39%,P=0.07)prior to repair than those with lower ET-1concentration.CONCLUSIONET-1 concentration is significantly variable in the perioperative period surrounding coarctectomy.Older children and infants have different responses to surgical repair suggesting different mechanisms of activation.Benjamin Steven Frank Tracy T Urban Suhong Tong Courtney Cassidy Max B Mitchell Christopher S Nichols Jesse A Davidson 2017World Journal of Cardiology2017,9,12:2
