Result: Porosis and inflammatory cell infiltration in the spinal cord, rupture of muscle bundles, hypertrophia and over growth of muscle cells and collagens, and inflammatory cell infiltration in the bladder wall could been seen under HE dyeing. Nissal dyeing showed the decrease of neurons at the injured segment, upper and lower segments of the spinal cord. Result of immunohistochemistry showed there were caspase-3 positive expression in all the segments. The injured spinal cord and bladder expressed significantly more caspase-3 positive results (P.0l), upper and lower segments were lower than the injured segments (P.01), but higher than the control team (P.0l).

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.
