However, this study discovers, after the investigation of "please" in the corpus of colloquial speech of London teenagers,"please" is combined with various syntactical structures such as imperative sentences, interrogative sentences with modal verbs, interrogative sentences with non-modal verbs, statements, and toneless clauses.

The invention provides a method for homopolymerizing conjugated dialkene or co-polymerizing conjugated dialkene and monovinyl aromatic hydrocarbon. The method comprises the following steps: the conjugated dialkene is homopolymerized or the conjugated dialkene and the monvinyl aromatic hydrocarbon are co-polymerized randomly. The method is characterized in that at least one alkali metal alkoxide compound expressed by the formula is used as a structure regulator; in the formula, R is linear chain or branched chain alkylidene radical having 1 to 10 carbon atoms; M is alkali metal selected from Li, Na, K, Rb and Cs.

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。
