IIT: Intensive insulin therapy; CIT: Conventional insulin therapy; TP: Total protein; ALB: Albumin; TG: Triglyceride; TC: Total cholesterol; FFA: Free fat acid. There were significant differences in values between preoperative days 0 and postoperative day 1 (^aP < 0.05), between postoperative days 1 and 3 (^cP < 0.05) and between postoperative days 3 and 7 respectively (^eP < 0.05) respectively. There was a significant difference between the two groups at the same time (^gP < 0.05).
