Background:Little is known about exercise cardiac power(ECP),defined as the ratio of directly measured maximal oxygen uptake with peak systolic blood pressure during exercise,on heart failure(HF)risk.We examined the association of ECP and the risk of HF.Methods:This was a population-based cohort study of 2351 men from eastern Finland.The average time to follow-up was 25 years.Participants participated at baseline in an exercise stress test.A total of 313 cases of HF occurred.Results:Men with low ECP(＜9.84 mL/mmHg,the lowest quartile)had a 2.37-fold(95％confidence interval(95％CI):1.68-3.35,p＜0.0001)hazards ratio of HF as compared with men with high ECP(＞13.92 mL/mmHg,the highest quartile),after adjusting for age.Low ECP was asso-ciated with a 1.96-fold risk(95％CI:1.38-2.78,p＜0.001)of HF after additional adjustment for conventional risk factors.After further adjust-ment for left ventricular hypertrophy,the results hardly changed(hazards ratio=1.87,95％CI:1.31-2.66,p＜0.001).One SD increase in ECP(3.16 mL/mmHg)was associated with a decreased risk of HF by 28％(95％CI:17％—37％).Conclusion:ECP provides a noninvasive and easily available measure from cardiopulmonary exercise tests in predicting HF.However,ECP did not provide additional value over maximal oxygen uptake

信息技术的有效应用不仅丰富了教学手段,还极大提高了各门学科的教学质量,尤其针对小学数学学科而言,信息技术独特的优势,促使小学生对严谨性极强的数学知识有了新的认识,有效推动学生对数学知识的学习与掌握.因此,在小学教学过程中,要依托学校信息化建设的优质内部环境与外部环境,有效将信息技术与小学数学整合,改变传统数学教学模式,进而有效提高学生对数学知识的理解与应用.
Background:Physical activity(PA)has substantial health benefits and is important in combatting chronic diseases,which have been associated with ele-vated levels of advanced glycation endproducts(AGEs).AGEs play a role in the aging process,and an associati
挖掘工科类课程隐藏的思政资源是“新工科”背景下课程思政建设的必要环节.针对工科类课程思政面临的思政方法欠缺、思政资源难挖掘的问题,提出一种“课程思政862法”,具体包括构建“八大思政观点”、梳理“六类思政素材”、归纳“两种思政实施方式”.教学实践表明,所提出的“课程思政862法”具有思政观点易于明确落实、思政素材易于按图索骥、思政方式易于操作实施的“三易”特点,取得了较好的课程思政效果,实践结果证明了“课程思政862法”的正确性与实用性,为工科类专业课程开展思政教育提供新的思路.
《普通高中语文课程标准(2017年版)》中提出了“语文学科核心素养”的概念,其中提出高中生必须具备审美鉴赏与创造力.小说作为四大文学体裁之一,以其深厚的文化底蕴和独特的审美价值来提升学生的语文素养.小说教学中教师应注重培养学生的审美能力,小说中的语言、人物形象以及环境描写等都是提高审美能力所需要学习的要素.因此,高中语文小说教学中审美能力的培养探究,希望给身在一线的语文教育工作者一些启发和思路,以便更好地提升高中生的语文审美素养与能力.
