Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.  相似文献   

Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com     

Wenchao Ma  Jimmy de la Torre 《Educational Measurement》2019,38(2):114-115

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献

齐海峰竞技成绩的灰色关联分析及GM(1,N)动态协调模型的研究     

孙俊生 《首都体育学院学报》2004,16(1):120-122

采用文献资料法和灰色关联度分析法,对我国优秀男子十项全能运动员齐海峰1999-2002年十项全能的比赛成绩进行统计与分析,运用GM(1,N)动态协调模型对其在总成绩不断提高的各个阶段诸因素间相互联系、相互影响的辩证发展关系进行多方位、多层次研究。结果表明:100米跑、铅球和跳远是影响齐海峰专项成绩的关键因素,其关联度分别为0.8928、0.7443和0.7571,研究还发现,齐海峰在成绩提高的每一个阶段中,系统处于不稳定和非协调发展,其中速度和速度——力量性项目落后是导致系统不稳定和非协调发展的主要因素。  相似文献

设计三种实验模型,即力竭游泳运动模型、递增负荷游泳训练模型、BSO排空GSH模型,研究三种模型对大鼠心肌中原癌基因c-jun和c-fos mRNA表达的影响。结果发现力竭运动后训练力竭组、注射BSO力竭组、对照力竭组的大鼠心肌中c-jun mRNA表达量与相对应的训练安静组、注射BSO、对照安静组均增加,大鼠心肌中c-fos安静组mRNA表达量增加。BSO力竭组的c-fos mRNA表达量高于对照力竭组。训练力竭组与对照力竭组相比c-fos mRNA表达量没有明显变化。由上述实验结果推出,长时间力竭运动机体活性氧产生增加,c-jun mRNA和c-fos mRNA的表达量增加,进而激活转录因子AP-1。  相似文献   

基于AdaBoost改进随机森林和SVM的 极化SAR地物分类     

张政  李世强 《中国科学院大学学报》2022,39(6):776-782

为提升极化合成孔径雷达(SAR)地物分类精度,提出一种基于AdaBoost改进型随机森林和支持向量机(SVM)结合的二级分类结构。首先将AdaBoost改进型随机森林作为初级分类器,该分类器能根据决策树的分类能力赋予权重,分类能力越强则权重越高,从而提升初级分类精度。初级分类器还能评估输入特征的重要性,获得重要性排名。根据重要性排名进行特征筛选,用筛选后的特征训练SVM分类器,获取二级分类结果。最后利用邻域投票法将两级分类结果融合。AIRSAR极化数据对比实验表明,该分类结构可有效提升极化SAR地物分类精度。  相似文献
