Effect of cuproptosis on acute kidney injury after cardiopulmonary bypass in diabetic patients

Figure 5 Comparison of copper ion levels between diabetic and non-diabetic patients. A: Copper ion levels in serum; B: Copper ion levels in urine. In two group, copper levels were significantly elevated in after cardiopulmonary bypass (CPB). But in diabetic patients, copper levels had significantly higher after CPB. Cu: Copper ion; CDB1 and CDU1: Patients without diabetes before cardiopulmonary bypass; CDB3 and CDU3: Patients without diabetes after cardiopulmonary bypass; CZB1 and CZU1: Patients with diabetes before cardiopulmonary bypass; CZB3 and CZU3: Patients with diabetes after cardiopulmonary bypass.
