It follows that the de-protonic reaction of hydroxide group for PVA had taken place in above solution, and the coordination group for deprotonic oxygen of PVA had produced more. These ligands interact with some Fe3+ of ferric hydroxide while the ferric hydroxide in new emergence is forming,causing the formation of Fe-PVA coordination polymer-the composition of the reddish brown resinoid substance.

推定PVA部分羟基在上述条件下发生脱质子反应而提供L-配位体，Fe盐水解生成初生Fe3的Fe3+，它既有空轨道，又有较强的正电场，故能吸引PVA高分子配位体L-上的氧而形成O→Fe配位键，从而发生L-与Fe3+离子间的交联反应，生成多核Fe-PVA配位聚合物而析出红棕色树胶状物。

Methods:The conservative region of mTOR gene was inserted into pLXIN reversedly, then the vector was packaged in PT67 cells by transfection with lipofectamine and transfected to VSMC. The efficiency of antisense inhibition was verified,and the changes of p70S6k and 4E-BP1 were also determined at the same time. The proliferation activity was determined by flowcytometry and MTT.

Generally, two hybridization events have happened in the generation of gynogenetic crucian carp: the first one occurred about 6, 000 years ago when maternal ancestor of C. a. gibelio hybridized with males of C. a. auratus (ancestor of C. a. colored variety) and a diploid hybrid was produced; the second one happened over 10, 000 years ago, when the diploid hybrid was backcrossed with one of its parental population, by which the current triploid gynogenetic crucian carp emerged.

初步推断出东北雌核生殖银鲫是通过鲫鱼种群间的两次杂交产生的，第一次杂交是母本的银鲫同源种群与父本的彩鲫同源种群杂交，形成二倍体杂种；第二次杂交是二倍体杂种与两个祖先鲫鱼种群之一回交，形成了今天的三倍体杂种银鲫。

Firstly, the acute cytotoxicity of profenofos on FG-9307 cells was studied, it was found that the cell growth rate was markedly reduced by profenofos at all the concentrations tested; and that the fine structures of the cells were also altered by profenofos, as evidenced by dilation of nuclear membranes and mitochondria cristae, and presence of enlarged lysosomes with engulfed organelles and numerous vacuoles in the cytoplasm.
