Abstract:
Objective:To explore the perioperative dynamic changes of cellular immune function and its clinical significance in patients with chest surgery.Methods:The numbers of CD3、CD4、CD4/CD8、CD8 T lymphocyte and nature killer(NK) cells in peripheral blood were examined in 45 patients with chest surgery before operation and 1、3、5 and 7 days after operation by flow cytometry.45 patients were devided randomly into groups.The perioperative changes of T lymphocyte subsets and NK cells were compared among mediastinal disease,pulmonary operation,esophagus and gastric cardia surgery.Results:CD4/CD8 decreased 1 day after surgery and CD4 decreased at the 3rd postoperative day in patients with chest surgery.In patients with mediastinal disease,CD4/CD8 decreased 1 day after surgery and CD4 decreased at the 3rd postoperative day.In patients with pulmonary operation,CD8 decreased at the 1st day and 7th day after surgery.NK cells decreased at the 5th postoperative day CD3 increased at the 5th day after surgery.CD4/CD8 increased at the 7th day after operation.In patients with esophagus and gastric cardia surgery,CD4/CD8 decreased 1 day after operation,CD3 and CD4 increased at the 7th postoperative day.All differences are statistically significant( P
