Objective To observe plasma concentration of adiponectin and high sensitive C reactive protein (HsCRP) in Type 2 diabetes mellitus(T2DM) with/without lower extremities vascular disease,and explore the influences of adiponectin and HsCRP in the genesis and development of them.Methods We selected 115 subjects in our hospital and divided them into 2 groups:normal control group and T2DM group,including simple T2DM and T2DM with diabetic lower extremities vascular disease;in addition,we measured plasma adiponectin and HsCRP with ELISA and scattered radiation turbidimetry for them.Results Plasma adiponectin concentration in the comparing group was higher than T2DM,and the level in simple T2DM patients was higher than the one with lower extremities vascular disease,showing an obviously decreased tendency,and significant differences were detected in plasma adiponectin concentration between groups (P
