通过实证检验发现，我国金字塔结构下民营上市公司的治理效应有以下特征：控制权与公司价值显著负相关，说明实际控制人掌握的控制权越大，公司价值越低；现金流权与公司价值显著负相关，这可能与我国民营上市公司控股股东的"掠夺性分红"行为有关；现金流权与控制权的分离率和公司价值负相关且未通过显著性检验，这可能与控股股东的"掠夺性分红"行为有关，也可能与市场的不完善、信息披露的不充分等有关；股权制衡度与公司价值显著正相关，说明我国民营上市公司的股权制衡机制能够产生一定程度的效果；实际控制人参与管理情况与在控股股东单位任职的董事比例和公司价值的关系均未通过显著性检验；公司规模与公司价值显著负相关；ROE对公司价值没有解释力。

5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.

Results were shown as followings:(1) Sodium selenite at 0～2.5 μmol/L significantly increased the antioxidative capacity of L-02 cells without having remarkable impact on SMMC-7721 cells;(2) Sodium selenite at concentrations above significantly increased telomerase activity, hTERT gene expression and telomere length of L-02 cells without significant impact on SMMC-7721 cells;(3) Sodium selenite at higher concentrations (larger than 5 μmol/L) resulted in peroxidation of L-02 cells, while scutellarin significantly counteracted its effect;(4) Selenium-rich amino acids from silkworm pupas in the range of 0.5～2.5 μmol/L Se significantly inhibited SMMC-7721 cell growth, induced apoptosis and cell cycle change, and the generation of reactive oxygen species.
