Results: The levels of CD152 in Group A showed an upward trend from the 3[sup]rd to 7[sup]th day, with a downward trend from the 7[sup]th to 14[sup]th day (20.
The levels of CD152 in Group A at postoperative days 3 and 7 were obviously higher than those in Groups B and C, while no significant difference could be found among values in the three groups at postoperative day 14.
