The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors. We design and implement an SOA(Service-Oriented Architecture)-based UTDD(urban traffic data mining development) with high expansibility and performance, which implement unified management and call of the data-mining application though defining a XML-based description of data-mining process and a common interface to call data-mining process, finally we build traffic flow prediction application model on UTDD.

The dynamic changes of the the neuron apoptosis and correlative genes in hippocampus of ACET-groups and twice-ACET-groups suggested that ACET can slower the apoptosis by inhibiting p~(53)and prolong the ascending period of p~(53) in 4 days after the seizure,this effect would weaken after 4 days.ACET may inhibit the descending of Bax,prolong its descending period and then promote its expression,in order to weaken the inhibition of the apoptosis during 4 to 10 days after seizure and then promote the apoptosis during 10 to 14 days after.This effect of ACET can be enhanced after treating again within 7 to 14 days later.
埋线组和二次埋线组大鼠海马神经元凋亡及相关基因表达的动态变化结果提示:埋线治疗在癫痫发作后的早期(4d内)可通过抑制促凋亡基因p~(53)蛋白表达、延缓其达峰值的时程,从而减缓神经元凋亡的发生,此作用在4d后减弱;埋线治疗抑制大鼠海马神经元凋亡的作用在癫痫发作后的中期(4d~10d)减弱,甚至在远期(10d~14d)出现促进凋亡的作用,可能是通过抑制Bax蛋白表达的下降、延长其降至低峰值的时程,促进Bax蛋白表达的回升的结果;在中远期(7d~14d)内予二次埋线治疗对该效应有续效叠加的作用。
