Objectives To observe the electrophysiologic effects of propafenone （Prop） on ischemic ventricular tachyarrhythmias. Methods A canine ischemic ventricular tachyarrhythmia model was established in open-chest dogs subjected to programmed electrical stimulation （PES） on 5-8 days after acute myocardial infarction. The electrophysiologic effects of propafenone were observed in the model. Results Propafenone distinctly lengthened the QTc interval （P 〉 0.01） and effective refractory period （ERP） of normal and ischemic ventricular myocardium （NERP and IERP） respectively （P 〉 0.01）, decreased the dispersion of ERP in ischemic myocardium and in left ventricle （P 〉 0.01）, and increased the diastolic excitability threshold of normal and ischemic ventricular myoeardium remarkably （P 〉 0.01）. Propafenone effectively prevented PES-induced ventricular tachycardia （VT） or ventricular fibrillation （VF）（P 〉 0.01） and ischemia-induced VT/VF （P 〉 0.05）. Conclusions The results indicated that the canine model produced by our methods is a worthy and reliable one, propafenone may be effective in preventing the onset of VT / VF after myocardial ischemic damage in dogs, and deserve further attention as an antifibrillatory agent.

Soybean(Glycine max) produces seeds that are rich in unsaturated fatty acids and is an important oilseed crop worldwide. Seed oil content and composition largely determine the economic value of soybean. Due to natural genetic variation, seed oil content varies substantially across soybean cultivars. Although much progress has been made in elucidating the genetic trajectory underlying fatty acid metabolism and oil biosynthesis in plants, the causal genes for many quantitative trait loci(QTLs) regulating seed oil content in soybean remain to be revealed. In this study, we identified Gm FATA1B as the gene underlying a QTL that regulates seed oil content and composition, as well as seed size in soybean. Nine extra amino acids in the conserved region of Gm FATA1B impair its function as a fatty acyl–acyl carrier protein thioesterase, thereby affecting seed oil content and composition. Heterogeneously overexpressing the functional Gm FATA1B allele in Arabidopsis thaliana increased both the total oil content and the oleic acid and linoleic acid contents of seeds. Our findings uncover a previously unknown locus underlying variation in seed oil content in soybean and lay the foundation for improving seed oil content and composition in soybean.

Just after transplanting, the vegetable has difficulty in nutrients uptake. To explore the effect of different fertilization on spring cabbage (Brassica oleracea L. var. capitata) production and fertilizer use efficiencies, this experiment consisting of six treatments was implemented and divided into three groups: 1) no fertilizer (NF) and vegetable planting fertilizer (VPF);2) conventional fertilizer (CF) and conventional fertilizer + vegetable planting fertilizer (CVPF);3) reduced fertilizer application (RFA) and reduced fertilizer application + vegetable planting fertilizer (RVPF). The results of this experiment indicated that the yields of spring cabbage treated by VPF increased by 38.20% in VPF, 16.00% in CVPF and 20.40% in RVPF than their controls respectively. Additionally, the VPF helped improve the total and economic yields of the spring cabbage in all groups, and the economic benefits increased by 38.21% in VPF, 15.97% in CVPF and 20.42% in RVPF than their controls respectively. Finally, the VPF was of benefit to spring cabbage to exploit the soil nutrients and helped improve the chemical fertilizer use efficiencies. Therefore, it is an efficient, economical and ecological fertilization for vegetable production to apply chemical fertilizers in combination with VPF.
