Club cell protein 16 as a biomarker in pulmonary contusion

The aim of the present study was to investigate the variation and clinical significance of the 16-kDa club cell protein (CC16) in patients with pulmonary contusion. A total of 42 patients with pulmonary contusion were divided into experimental groups I (n=24, moderate pulmonary contusion) and II (n=18, severe pulmonary contusion). An enzyme-linked immunosorbent assay was used to detect the serum levels of CC16 in the two groups of patients within 24 h after the incident and at days 1, 3, 7 and 14 after treatment. The results were compared with another 16 healthy subjects included as the controls. The serum CC16 level at each time point was higher in the two experimental groups compared to the controls (P
