目的：了解偏头痛患者丘脑血流的变化。方法：用９９ｍＴｃ－六甲基两二胺肟和Ｎｏｖｏ－８１０高分辨率ＳＰＥＣＴ仪，以感兴趣区（ＲＯＩ）相对放射性计数百分率（ＲＯＩ％）为指标，对６０例次偏头痛患者的丘脑血流变化作了定量分析。结果：与无预兆偏头痛组的平均ＲＯＩ％值（２４９．Ｉｆ１４．９）相比，预兆偏头痛组ＲＯＩ％升高（２５９．１±１７．１），差异有显著意义（Ｐ＜０．０５）；偏瘫、偏身感觉异常预兆偏头痛组升高更明显（２６３．８±１７．２），差异有极显著性（Ｐ＜０．０１）；而单纯视觉预兆组稍升高（２５５．１±１６．４），差异无显著意义（Ｐ＞０．０５）。结论：偏瘫、偏身感觉异常预兆组丘脑血流升高，原因可能为：①缺血后高灌注。②除丘脑外，其它脑区血流减少。③各种神经、化学性刺激的结果。

The interplay between soil physical parameters during the recovery from anoxic stresses （reoxidation） is largely unrecognized. This study was conducted to chaxacterise the soil aeration status and derive correlations between variable aeration factors during reoxidation. Surface layers （0-30 cm） of three soil types, haplic Phaeozem, Mollic Gleysol, and Eutric Cambisol （FAO soil group）, were selected for analysis. The moisture content was determined for a range of pF values （0, 1.5, 2.2, 2.7, and 3.2）, corresponding to the available water for microorganisms and plant roots. The variability of a number of soil aeration parameters, such as water potential （pF）, air-filled porosity （Eg）, oxygen diffusion rate （ODR）, and redox potential （Eh）, were investigated. These parameters were found to be interrelated in most cases. There were significant （P 〈 0.001） negative correlations of pF, Eg, and ODR with Eh. A decrease in water content as a consequence of soil reoxidation was manifeste. by an increase in the values of aeration factors in the soil environment. These results contributed to understanding of soil redox processes during recovery from flooding and might be useful for development of agricultural techniques aiming at soil reoxidation and soil fertility optimisation.

成功的提高喷吹率依赖于煤气分布的控制和喷吹煤粉的足够的燃烧率，实验室用一个空的炉子和一个装有焦炭床的炉子研究煤粉在回旋区的燃烧，试验表明在艾莫伊登厂使用的高挥发分煤有较高的燃烧率。在高炉的高喷煤比试验期间，从风口水平的焦炭结构和炉尘取样调查表明在喷吹率为１９０－２１０ｋｇ／ｔ铁时喷吹的煤粉可得到有效的利用。从炉顶逸出的喷煤碳含量小于１％，而且不会受煤粉喷吹率的影响。

Purpose It is well recognised that injury prevention training can reduce injury incidence,however current coach education pathways do not provide grass-root coaches with the knowledge and confidence to deliver such training to youth *** aim of this study was to explore differences in knowledge,understanding,attitude and confidence to deliver such injury prevention training in three European *** A total of 269 grass-root soccer coaches from 3 European countries(Czech Republic,UK,Spain)were recruited for this study.A validated questionnaire exploring knowledge,understanding,attitude towards and confidence to deliver youth injury prevention training was completed prior to a 2 h workshop on injury prevention *** between countries was examined using Bayesian factors to quantify the evidence for and against the hypothesis of independence(h0)by assuming a Poisson sampling scheme(as there was no a priori restriction on any cell count,nor on the grand total)(BF10 Poisson).Results Current knowledge,attitude and confidence to deliver injury prevention training to youth players was poor across all three European *** few coaches were currently using injury prevention training in their coaching sessions(23%).There were some country specific differences for attitude towards injury prevention training and confidence to deliver injury training,with Spanish coaches reporting a more positive attitude and confidence to deliver such *** fewer coaches in the UK were using injury prevention training compared to coaches in Spain and the Czech *** As coaches identified a need for coach education and few were delivering injury prevention training,there is a clear need to embed and implement this programme into the grassroots coaching framework of sports governing bodies to improve adoption,implementation and maintenance.

Purpose jump-landing assessments provide a means to quantify an individual’s ability to attenuate ground reaction forces,generate lower limb explosive power and maintain joint *** order to identify risk factors that can be targeted through appropriate training interventions,it is necessary to establish which(scalar)objective kinetic,kinematic,and performance measures are most associated with lower-extremity *** Online searches of MEDLINE,SCOPUS,EBSCOhost,SPORTDiscus and PubMed databases were completed for all articles published before March 2020 in accordance with PRISMA *** 40 articles investigating nine jump-landing assessments were included in this *** 79%of studies using drop jump(n=14)observed an association with future injury,while only 8%of countermovement jump studies(n=13)observed an association with injury *** 57%of studies using unilateral assessments found associations with risk of injury(n=14).Studies using performance measures(jump height/distance)as outcome measure were only associated with injury risk in 30%of ***,those using kinetic and/or kinematic analyses(knee abduction moment,knee valgus angle,knee separation distance,peak ground reaction force)found associations with injury in 89%of *** The landing element of jump-landing assessments appears to be superior for identifying individuals at greater risk of injury;likely due to a closer representation of the injury ***,jump-landing assessments that involve attenuation of impact forces such as the drop jump appear most suited for this purpose but should involve assessment of frontal plane knee motion and ground reaction forces.
