Objective: We sought to d.scribe clinical characteristics of emergency d.partment patients ultimately d.agnosed.with Takotsubo Card.omyopathy (TCM) and.to explore the causal role that stress may play in its pathogenesis. Method.: We performed.a retrospective chart review analyzing all myocard.al infarction patients with non-obstructive coronary artery d.sease on card.ac catheterization to assess for the presence of TCM. Various clinical d.ta, includ.ng the pres-ence of stressors, from emergency d.partment record. were reported. We also analyzed.factors from several stud.es (includ.ng ours) to assess the true causality of stress in the d.velopment of TCM. Results: Twelve Ed.patients out of 2,179 charts reviewed.were id.ntified.as having TCM. Most were female, post-menopausal, and.had.chest pain, but only half had.a specific stressful event id.ntified.in the Ed. One-third.of patients had.no stressful event id.ntified.d.ring their hospital stay. Several other stud.es suggest that stressful events are associated.with increased.d.agnoses of TCM, but we found.that causality of stress cannot be substantiated. Conclusion: Stressful events are often not id.ntified.in emergency d.partment patients ultimately d.agnosed.with TCM. The causative nature of stress in the d.velopment of TCM cannot be firmly established.from any existing d.ta.

目的 :研究抗惊厥药加巴喷丁对内脏疼痛的作用及其对脑脊液中氨基酸释放的影响。方法 :4 8只Sd.鼠分别随机接受腹腔内注射生理盐水、加巴喷丁 5 0mg·kg-1、加巴喷丁 10 0mg·kg-1或加巴喷丁 2 0 0mg·kg-1,4 0min后经腹腔内注射 0 .6 % (体积分数 )醋酸 4ml·kg-1诱发内脏疼痛。观察并比较不同组大鼠 1h内醋酸诱发腹肌收缩次数。另选择两组大鼠在戊巴比妥麻醉下 ,通过置入蛛网膜下腔的微透析管采集脑脊液 ,应用高压液相法测定腹腔内注射 0 .6 %醋酸后透析脑脊液中氨基酸浓度的变化 ,包括谷氨酸、天门冬氨酸、丝氨酸、甘氨酸、谷氨酰胺。比较加巴喷丁预处理 (10 0mg·kg-1)对内脏疼痛后脑脊液中氨基酸释放的影响。结果 :加巴喷丁以剂量相关方式减低内脏疼痛行为学改变。腹腔内注射醋酸后 ,脑脊液透析液中谷氨酸、天门冬氨酸和丝氨酸浓度明显增加 ,而谷胺酰胺和甘氨酸增加差异无显著性。加巴喷丁预治疗可明显抑制醋酸引起的脑脊液中谷氨酸、天门冬氨酸和丝氨酸浓度增高。结论 :加巴喷丁可有效抑制醋酸诱发的内脏疼痛 ,其抑制作用可能与抑制伤害性刺激诱发的中枢兴奋性氨基酸释放有关。

The search for patterns or motifs in d.ta represents a problem area of key interest to finance and.economic researchers. In this paper, we introd.ce the motif tracking algorithm （MTA）, a novel immune inspired.（IS） pattern id.ntification tool that is able to id.ntify unknown motifs of a non specified.length which repeat within time series d.ta. The power of the algorithm comes from the fact that it uses a small number of parameters with minimal assumptions regard.ng the d.ta being examined.or the und.rlying motifs. Our interest lies in applying the algorithm to financial time series d.ta to id.ntify unknown patterns that exist. The algorithm is tested.using three separate d.ta sets. Particular suitability to financial d.ta is shown by applying it to oil price d.ta. In all cases, the algorithm id.ntifies the presence of a motif population in a fast and.efficient manner d.e to the utilization of an intuitive symbolic representation. The resulting population of motifs is shown to have consid.rable potential value for other applications such as forecasting and.algorithm seed.ng.
