Aims: We sought to determine whether the extent of myocardial ischaemia on the admission electrocardiogram(ECG) has independent predictive value for short-term risk stratification of patients with non-sT-segment elevation acute coronary syndromes(Nste ACs). Although the presence of ischaemic ECG changes on admission has been shown to predict outcome, the relationship between the extent of ECG changes and the risk of cardiac events is still ill defined. Methods and results: We analysed the admission ECGs of 5192 ACs patients enrolled in the GUsTO-IIb trial, without an ECG indication for thrombolysis. ECG tracings showing one or more of the following were eligible: sT-segment depression >0.5 mm, T-wave inversion >1 mm, and sT-segment elevation >0.5 mm butles associated with unfavourable 30 day outcomes in a univariable analysis were further assessed in a multivariable logistic regression model including independent clinical predictors. In the multivariable clinical, enzymatic, and ECG model, the sum of sT-segment depression(in millimetres) in all leads was a powerful independent predictor of 30 day death(Ps increase in risk with the extent of sT-segment depression. The sum of sT-segment depression(Psence of minimal inferior sT-segment elevation(Pterior sT-segment elevation(P=0.0182) were also independent predictors of the composite of death and myocardial infarction or reinfarction.

A 112-day experiment was conducted to economically evaluate the production of eggs from commercial layers submitted to diets supplemented with levels of plant extracts (dried turmeric powder) added or not to vitamin E. A total of 432 20-week-old white layers were used, distributed in an entirely randomized design, in a 4 × 3 factor scheme (turmeric extract levels and vitamin E levels), with 6 repetitions of 6 birds per cage. The treatments consisted of four levels of turmeric extract inclusion (0;0.1%;0.2% and 0.3%) and three levels of vitamin E inclusion (0;50 and 100 IU/kg). The results calculated at work were favorable to the activity, and the items that most influenced the expenses in the effective production cost were: poultry, feed and labor, respectively. The best economic response in egg production was obtained by layers that consumed 100 IU/kg vitamin E and 0.2% turmeric;because the leveling point represents that the activity equals the revenues with the costs. The best profitability index was found in treatment that contained 50 IU/kg vitamin E and 0.1% turmeric com (16.78%).

先秦儒家由“天”出发，提出了诸如“天民 ”这样的极富人文色彩和人道意义的范畴及命题，并因此建立起了其独具特色的人道价值观，但是，由于他们在智愚问题上的过分关注和强调，而使得其人道价值观在现实政治层面，几无实践性意义可言。也就是说，先秦儒家同时强调的智愚说，在很大程度上消解、甚至否定了其原有的人道价值论，进而对中国传统文化发生了重大影响。

菲律宾农村土地分配的不公正状况在马科斯统治初期依然严峻，土地问题的急剧升级加剧了政体的演变，但军管法下的土改并没有使农民的生活状况得到明显改善。马科斯政府虽然与“旧寡头政治执政者们”逐步脱离，但和军人集团、政策制定者及商业权贵结合，实行“亲朋资本主义”政治，继续忽视农民的利益，农村基层组织也为地主势力所把持。制度创新的滞后严重阻碍了菲律宾农村土地改革和农村发展。
