Index of microcirculatory resistance: state-of-the-art and potential applications in computational simulation of coronary artery disease

The dysfunction of coronary microcirculation is an important cause of coronary artery disease (CAD). The index of microcirculatory resistance (IMR) is a quantitative evaluation of coronary microcirculatory function, which provides a significant reference for the prediction, diagnosis, treatment, and prognosis of CAD. IMR also plays a key role in investigating the interaction between epicardial and microcirculatory dysfunctions, and is closely associated with coronary hemodynamic parameters such as flow rate, distal coronary pressure, and aortic pressure, which have been widely applied in computational studies of CAD. However, there is currently a lack of consensus across studies on the normal and pathological ranges of IMR. The relationships between IMR and coronary hemodynamic parameters have not been accurately quantified, which limits the application of IMR in computational CAD studies. In this paper, we discuss the research gaps between IMR and its potential applications in the computational simulation of CAD. Computational simulation based on the combination of IMR and other hemodynamic parameters is a promising technology to improve the diagnosis and guide clinical trials of CAD.

不同强度运动对大鼠冠状动脉CGRP、ET- 1 和NOS 表达的影响

目的:探讨运动对大鼠冠状动脉降钙素基因相关肽(CGRP)、内皮素(ET-1)和一氧化氮合酶(NOS)表达的影响.方法:健康雄性SD3月龄大鼠24只,分为安静对照组、小强度运动组和大强度运动组,运动组采用大鼠跑台运动方式,建立大鼠不同强度运动模型,运用免疫组织化学SABC法研究不同强度运动对大鼠冠状动脉CGRP、ET-1、神经型一氧化氮合酶(nNOS)、诱导型一氧化氮合酶(iNOS)和内皮型一氧化氮合酶(eNOS)表达的影响.结果:与安静对照组比较,小强度运动组和大强度运动组CGRP、nNOS、iNOS和eNOS均显著性升高,小强度运动组ET-1显著降低,大强度运动组ET-1显著性升高.与小强度运动组比较,大强度运动组CGRP、ET-1、nNOS、iNOS和eNOS的表达变化均有显著性差异.小强度运动组和大强度运动组ET-1/CGRP和ET-1/NOS比值均低于安静对照组.结论:运动可引起大鼠冠状动脉CGRP、ET-1及NOS的表达变化,且与运动强度关系密切.因此认为,不同强度运动引起ET-1/CGRP和ET-1/NOS比值的变化可能是运动引起心血管生物功能改变的因素之一.     

经验、体验与文学

对于文学创作来说, 经验与体验是不同的。经验是他的生物的或社会的阅历。体验是经历中见出个性、深义和诗意的情感。经验只是知识的积累。体验是价值的叩问。体验具有超越性。它给文学带来的是情感的诗意化、意义的深刻化和感受的个性化。体验的美学功能     

Exercise and inflammation in coronary artery disease: A systematic review and meta-analysis of randomised trials

ABSTRACT

Current evidence suggests that chronic inflammation contributes to the development of coronary artery disease (CAD). Interestingly, exercise may constitute a method of reducing inflammation in this patient population. As such, this systematic review and meta-analysis examined the evidence generated by randomised studies that investigated the effect of exercise on inflammatory biomarkers in CAD. Literature was sought from various sources. Outcomes were pooled in a random-effects model to calculate standardised mean differences (SMD) with 95% confidence intervals (CI). Twenty-five studies were reviewed; post-intervention C-reactive protein (SMD: ?0.55 (95% CI: ?0.93, ?0.16), P = 0.005), fibrinogen (SMD: ?0.52 (95% CI: ?0.74, ?0.29, P = <0.00001)), and von Willebrand factor (SMD: ?1.57 (95% CI: ?2.23, ?0.92), P = <0.00001) values were significantly lower in exercise groups compared to controls. In addition, qualitative analyses identified evidence that supports a beneficial effect of exercise on these acute-phase reactants. However, the impact of exercise on anti–inflammatory cytokines, adhesion molecules, and chemokines is equivocal, which may be attributed to a paucity of research. Nevertheless, the findings of this review suggest that exercise induces an anti–inflammatory effect in CAD patients. Although, the quality of evidence needs to be improved by further randomised studies with high methodological qualities and large sample sizes.     

The Use of Clinical Reasoning Skills in the Setting of Uncertainty: A Case of Trial Femoral Head Migration

Clinical skills and medical knowledge enable physicians to overcome the uncertainty of emergent and rare clinical scenarios. Recently, a growing emphasis on evidence-based medicine (EBM) has flooded medical curricula of universities across the globe with guideline-based material, and while it has given teachers and students new tools to improve medical education, clinical reasoning must be reaffirmed in its capacity to provide physicians with the ability to solve unexpected clinical scenarios. Anatomical education in medical school should have two main objectives: to acquire anatomical knowledge and to develop the skill of applying that knowledge in clinical scenarios. The authors present a clinical scenario in which an unexpected and rare complication occurred during a routine elective hip replacement surgery. The general surgeon presiding over the case, also an anatomy professor, solved the problem using clinical reasoning and anatomical knowledge. It was a clear example of how clinical reasoning is key in approaching unprecedented, rare, or unknown complications. The intention of this scenario is to remind colleagues and medical schools that, although EBM is the standard, educators must uphold sound clinical reasoning to best prepare health care providers for their careers.

带凸缘圆筒件成形数值模拟

拉深成形中凸、凹模圆角半径一直都是成形的关键,严重影响成形的质量。以板料成形理论和abaqus软件为基础,探讨带凸缘圆筒件拉深成形过程中凸、凹模圆角半径的影响。结果表明：拉深成形过程中,板料最大应力主要集中在凸、凹模圆角半径处;在一定范围内拉深时采用较大的圆角半径,整形以后侧壁的厚度也较大;但凸、凹模圆角半径处的壁厚变化则刚好相反,随着首次拉深圆角半径的增大,壁厚逐渐变薄,甚至出现破裂和折叠;运用有限元数值模拟能很好地预测其成形缺陷,并可对计算参数进行优化。
