Solar eruptive events,like flares and coronal mass ejections,are characterized by the rapid release of energy that can give rise to emission of radiation across the entire electromagnetic spectrum and to an abrupt significant increase in the kinetic energy of *** energetic phenomena can have important effects on the space weather conditions and therefore it is necessary to understand their origin,in particular,what is the eruptive potential of an active region(AR).In these case studies,we compare two distinct methods that were used in previous works to investigate the variations of some characteristic physical parameters during the pre-flare states of flaring *** methods consider:i)the magnetic flux evolution and magnetic helicity accumulation,and ii)the fractal and multi-fractal properties of flux concentrations in *** comparative analysis is based on time series of photospheric data obtained by the Solar Dynamics Observatory between March 2011 and June *** selected two distinct samples of ARs:one is distinguished by the occurrence of more energetic M-and X-class flare events,that may have a rapid effect on not just the near-Earth space,but also on the terrestrial environment;the second is characterized by no-flares or having just a few C-and B-class *** found that the two tested methods complement each other in their ability to assess the eruptive potentials of ARs and could be employed to identify ARs prone to flaring *** on the presented case study,we suggest that using a combination of different methods may aid to identify more reliably the eruptive potentials of ARs and help to better understand the pre-flare states.

目的 :调查中国健康人群 12导联心电图Q波参数的正常范围 ,评估传统的Q波标准。方法 :采集5 36 0例 (男 36 14例 ,女 174 6例 )健康人心电图资料 ,并按性别分为 5个年龄组 ,计算各年龄组Q波时限、振幅和Q/R比例的中位数和正常上限值 ,以及各导联上QS波类型的发生率。结果 :男性Q波时限稍长于女性 ,性别差异为 2～ 5ms。Q波时限正常范围在Ⅰ、V5和V6导联≤ 2 5ms ,在aVL导联≤ 4 5ms ;在下壁导联中 ,Q波时限正常范围在Ⅲ导联 <4 0ms,在Ⅱ和aVF导联 <30ms。各导联的Q波振幅正常上限值在不同年龄组间显示较大的变异。Q/R比例的正常上限值在Ⅰ、Ⅱ导联一般 <2 5 % ,而在V5和V6导联 <15 % ;aVL、Ⅲ和aVF导联的Q/R比例正常上限值在不同年龄组间显示较大的变异。QS波类型在V1导联的发生率为 1.5 % (80 / 5 36 0 ) ,在V2 导联的发生率为 0 .2 % (9/ 5 36 0 )。除Ⅲ和aVL导联外 ,传统的Q波标准的诊断特异性可达到 99%～ 10 0 %。结论 :Q波参数的正常值标准有明显的导联依赖性。适当调整传统的Q波标准。

Traumatic rupture of the right diaphragmatic dome with herniation of a segment of the hail into the thorax is a rare lesion. It is often the result of a thoraco-abdominal trauma. It can generally lead to early or late cardiopulmonary complications due to compression. The objective of this clinical case is to study the physiopathological mechanisms, the diagnostic and therapeutic modalities of this complication. The diagnosis is often difficult in front of a diaphragmatic rupture since there are no specific clinical signs. In our case, the clinical picture on arrival was that of a high occlusion in an immediate postoperative context. The X-ray which makes it possible to visualize the ascended organs but more difficultly the rupture itself could not be carried out. Treatment is essentially surgical. Although the thoracic approach is preferred by several surgeons because of the difficulties of exposing the diaphragm in the presence of the liver, we chose the abdominal approach instead. The postoperative course is made up of parietal suppuration.

世界核心医学期刊文摘（心脏病学分册） 2006年第8期2卷 26-27页

Aims: Contemporary data on the incidence of unrecognized myocardial infarction(MI) among subjects aged 55 and older are limited. Methods and results: We studied the incidence of recognized and unrecognized MI in the Rotterdam Study, a population-based cohort of men and women aged 55 and older. The baseline examination was performed during 1990-93, with follow-up examinations during 1994- 95, and 1997-2000. Baseline and follow-up 12-lead ECGs were analysed by the Modular ECG Analysis System. The 5148 participants who had no evidence of prevalent infarction were the subjects for analysis. Incident recognized infarction was defined as the occurrence of a fatal or non-fatal event coded as 121 according to the International Classification of Diseases, 10th edition. A repeat ECG was available in 4187 subjects. An unrecognized infarction was considered to have occurred if there was electrocardiographic evidence in the absence of a clinically recognized event. During a median follow-up of 6.4 years, 141 incident recognized infarctions occurred and the incidence rate of this event was 5.0 per 1000 person years. The incidence was higher in men(8.4) than in women(3.1). The incidence rate of unrecognized infarction was 3.8 per 1000 person years. Men(4.2) and women(3.6) had approximately similar incidence. Hence, the proportion of unrecognized infarction was lower in men(33% ) than in women(54% ). This difference in proportion of unrecognized infarctions was independent of age. Conclusion: A high proportion of incident MIs remains clinically unrecognized. As a history of MI is associated with an increased risk of repeat cardiovascular complications, our data suggest a need for periodical electrocardiographic screening to recognize(prevalent) infarctions and to install effective preventive treatment in those aged 55 and older.
