作者： Leanna M.ross ryan r.porter J.Larry Durstine Department of Exercise Science Norman J.Arnold School of Public Health University of South Carolina

Exercise training provides physiological benefits for both improving athletic performance and maintaining good health. Different exercise training modalities and strategies exist. Two common exercise strategies are high-intensity interval training （HIIT） and moderate-intensity continuous exercise training （MCT）. HIIT was first used early in the 20th century and popularized later that century for improving performance of Olympic athletes. The primary premise underlying HIIT is that, compared to energy expenditure-matched MCT, a greater amount of work is performed at a higher intensity during a single exercise session which is achieved by alternating high-intensity exercise intervals with low-intensity exercise or rest intervals. Emerging research suggests that this same training method can provide beneficial effects for patients with a chronic disease and should be included in the comprehensive medical management plan. Accordingly, a major consideration in developing an individual exercise prescription for a patient with a chronic disease is the selection of an appropriate exercise strategy. In order to maximize exercise training benefits, this strategy should be tailored to the individual＇s need. The focus of this paper is to provide a brief summary of the current literature re^ardin~ the use of HIIT to enhance the fimctional capacity of individuals with cardiovascular, pulmonary, and diabetes diseases.

While we eagerly anticipate SMILE’s(Solar wind Magnetosphere Ionosphere Link Explorer)unprecedented X-ray observations of the Earth’s magnetosheath and the initiation of a new era of magnetospheric research,it seems appropriate to look ahead to the abilities of the next generation of astrophysics *** these,the Line Emission Mapper(LEM),a large aperture micro-calorimeter based mission,is currently planned to be able to observe the magnetosheath at high spectral resolution(~2 eV).With a field of view of~30′,LEM will allow higher spatial resolution and higher cadence measurement of the motion of a very small portion of the magnetopause over relatively short periods of time(multiple hours),complementing SMILE’s global ***’s strength is its spectral *** will be able to measure the abundance of a broad range of elements and ionization states,many of which are inaccessible to current in situ instruments,and will be able to separate the emission from the magnetosheath from the emission from the cosmic X-ray background using the difference in their relative velocities.

目的探讨经胸三维高机械指数诊断超声联合微泡增强溶栓效果、改善缺血心肌微灌注的可行性。方法将15只冠状动脉左前降支血栓栓塞模型猪分为实验组(n=8)和对照组(n=7)。实验组给予组织型纤溶酶原激活剂(tPA)静脉注射和脂质微泡静脉输注,同时对心前区予高机械指数三维超声辐照30min;对照组仅予tPA静脉注射及微泡静脉输注。观察治疗90min后阻塞冠状动脉再通率、治疗前及治疗90min后缺血区室壁增厚率、危险心肌面积、治疗前及治疗30、60、90min后心电图抬高ST段回落情况。结果治疗90min后,两组冠状动脉再通率差异无统计学意义;实验组室壁增厚率显著高于治疗前,而对照组治疗前后室壁增厚率差异无统计学意义。实验组治疗30、60、90min后,心电图抬高ST段均较治疗前显著回落,而对照组仅在治疗90min后有回落。实验组治疗90min后危险心肌面积较治疗前显著降低,对照组无明显变化;实验组冠状动脉造影无再通者(n=5)治疗90min后造影所示缺血心肌面积较治疗前显著降低。结论冠状动脉造影未显示血管再通时,经胸三维高机械指数超声联合微泡可显著改善猪阻塞区心肌微循环灌注。

根据生长在英国1年的、多点观察数据,模拟了Avalon品种冬小麦生长点的早期发育,用有关的天气资料优化了出苗至二棱期、二棱期至小穗分化末期,2个时期持续时间的参数值。对各种作物,通过作物发育指标累积值之间的剩余方差,又对不同模式进行了比较。以ArCWHEAT作物模式中的发育子模式为出发点,用日平均温度代替白天温度正弦曲线变化。将优化参数值与初始值加以比较,显示出前者对光周期的敏感较大,而对温度和春化敏感很小。研究发现,这些资料对温度和光周期的反应都是非线性关系,还没有一个表现出使这些数据与改进过的线性反应相一致。表示发育速率Ar-CWHEAT的子模式,它作为一个对温度、光周期和春化分别作出对应的产物与不同的选择模式作比较。然而,就这些资料而论,没有一个模式比ArCWHEAT公式拟合得好,但也看不出是坏的。当用独立数据检验时,预测二棱期的优化参数比较精确,而预测小穗分化末期优化参数的精确与初始值相仿。
