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.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
