Combined with animal model of peradaptation to myocardium ischemia , the research observed the level of enzymatic dynamics of myocardium, SOD,MDA,ET and correlation peptide of calcitonin gene in peripheral blood and cardiac function, apoptic cell and expression of apoptosis regulatory gene, ultrastructure of myocardium with BIOPAC16, in situ end labeling and hybridism, optic microscope and electron microscope. The study of animal model of peradaptation to myocardium ischemia illustrated that the peradaptation and pretreatment with Wenxin capsule could be positively protective for the injury of ischemia reperfusion. The protection is mainly reflected by reduction of infarction area, correction of heart rhythm abnormality of ischemia reperfusion, melioration of the contraction and relaxation function of myocardium, recovery of the subcellular structure and themelioration of the abnormality of biochemical and bioactive substance in the myocardium.

Test and analytical studies indicated that (1) connection moment strengths in positive bending were similar but in negative bending were different on the order of 0.72 and 0.6 percent compared to the bare steel beam subassembly so that the self-centering behavior of the subassemblies with the composite concrete slab was not observed,(2) force-transferring mechanism in the connection proposed was able to predict the force-deformation relationship of the subassembly with the composite concrete slab, and (3) a general-purpose nonlinear finite element analysis program ABAQUS was used to perform the correlation study on the subassemblies with and without composite concrete slab.

The incidence rates and duration of ventricular dilation-induced arrhythmias in each of verapamil, chelerythrine or glibenclamide group were similar to those in control group. Conclusion Ventricular dilation may induce arrhythmias in isolated rat hearts, which is inhibited by ischemic preconditioning. The transient increase in [Ca(superscript 2+)] appeared to be a triggering factor in the process of ischemic preconditioning. K channel PKC might also play an important roles in this process.
