ABSTRACT
Objective To explore the value f high sensitive c-reactive protein (hs-CRP) and CD4/CD8 ratio for monitoring of lung infection in elderly patients with esophageal cancer through detecting hs-CRP ,white blood cell (WBC)parameters and CD4 /CD8 ratio .Methods A total of 89 lung infection elderly patients with esophageal cancer after surgery from August 2012 to Decem-ber 2014 were collected as observation group ,special protein instrument ,blood cell analyzer and flow cytometry instrument were used to detect the hs-CRP ,WBC parameters ,CD4/CD8 ratio ,and compared with 82 cases of retired veteran cadres physical exami-nation for the same period in the control group .Results The hs-CRP ,WBC parameters ,CD4/CD8 in the preoperative group and the control group had no significant difference (P> 0 .05) .The three indicators in the preoperative group ,infection group and 3 days group had significant differences (P < 0 .05) ,although CD4/CD8 ratio in the cure group improved ,had not been completely im-proved .Conclusion Hs-CRP in diagnosis and monitoring of therapeutic efficacy is better than WBC parameters ,in the treatment of lung infection in elderly patients with esophageal cancer ,besides use the anti-infection treatment ,promote immune function recovery should not be ignored .
