Results: Neonatal rats in hypoxic-ischemicgroup behaved restlessness, cyanosis, deep and rapid breath, astasia, lethargy, irritation and spasm; There were local pyknosis, fragmentation, dissymmetry, blur or disappearance of nucleoli, raritas of ground substance in left cerebral cortex; but there was no statistic significance in chinese traditional medicine group and sham group. The expression of HIF-1α mRNA in brain tissue of experimental group and chinese traditional medicine group were higher than that in sham group, especially chinese traditional medicine group at 3d; HIF-1α positive cells were found in cerebral cortex and hippocampus. There were more HIF-1α positive cells in experimental group and chinese traditional medicine group and mainly in vascular endothelial cells.

结果 缺氧缺血后大鼠相继表现为烦躁不安、全身发给、呼吸加深加快、站立不稳、嗜睡、激惹或间断发作的痉挛和抽搐；HE染色显示实验组大鼠左侧大脑皮层出现局灶性神经元核固缩，核碎裂，核仁偏位，不清或消失，基质疏松；中药组大鼠脑组织结构基本接近假手术组，无明显水肿和坏死表现；实验组和中药组大鼠脑组织HIF-1α mRNA表达较假手术组明显增加，尤其是中药组实验第3日者；免疫组化显示实验组和中药组各时间点大鼠大脑皮层和海马区均可见不同程度的HIF-1α表达，明显高于假手术组，阳性表达主要在血管内皮细胞，海马和皮层的锥体细胞亦有HIF-1α阳性细胞分布。

Field investigation and analyses of the grain size, geochemical, stable carbon isotope etc climate proxies all indicate that this region, in about 14000aBP, u nderwent the expansion of the swamp. Subsequently, the swamp, because of aridity , began to decrease in area, and even disappeared. This process was followed by an immediate flooding period. The region, after the Younger Dryas cooling event (108000～10200aBP), came into the warming period of the Holocene, and then clima te in the region fluctuated subsequently.

张强通过区域地貌调查及对南京浦镇林峰桥剖面沉积物进行粒度、地球化学和稳定碳同位素等环境替代指标的分析研究，结果表明：本区在14000aBP左右先后经历了沼泽扩张期，此后气候变干，沼泽开始退缩，直至消失，在经过了长时间的沉积间断后又经历一次洪水泛滥期。

And then hp version discontinuous space-time finite element methods is used for a kind of Volterra integrodifferential parabolic equation with weakly singular kernel.The uniqueness of the approximate solution of the equation and the error estimate for time in L_2 norm and space in L_2 norm is obtained.

其次利用hp间断有限元方法研究一类Volterra偏积分微分方程，证明了离散解的存在唯一性，并得到了时间L_2、空间L_2模的指数型误差估计。
