After treatment , the OGTT2hPG and FPG were both decreased significantly ( both P < 0.05 ) in the two groups , compared between the two groups , the differences of FPG [ ( 0.41 + / - 0.42 ) mmol/L vs ( 0.05 + / - 0.08 ) mmol/L ] and OGTT2hPG [ ( 0.85 + / - 0.53 ) mmol/L vs ( 0.17 + / - 0.19 ) mmol/L ] were both statistically significant .
