Results As compared to DM control group, levels of GSP, myocardial enzymes and myocardial Ang Ⅱ were much lower in APS group, while levels of insulin, C-peptide and plasma Ang Ⅱ were the same. Levels of expression of collagen Ⅰ and the ratio of collagen Ⅰ/collagen Ⅲ in APS group were lower than those in DM group. APS group showed lower levels of chymase mRNA expression and activity than those in DM control group, while there was no diference in ACE mRNA expression and activity between the two groups.

结果 APS组血糖、糖化血清蛋白、心肌酶谱和心肌Ang Ⅱ水平较DM组显著下降，胰岛素、C肽、血浆AngⅡ水平和DM组无差异；APS组心肌Ⅰ型胶原表达和Ⅰ/Ⅲ型胶原比值较DM组显著下降；APS组chymase mRNA表达和活性均显著低于DM组，ACE基因的表达和活性与DM组无显著性差异。
