Abstract
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<0.01). The difference was significant when regarding the levels of CC16 measured within 24 h after contusion and at days 1, 3, 7 and 14 after treatment (P<0.01); however, the levels appeared to decline. In addition, the levels at each time point in experimental group II were significantly higher compared to group I (P<0.01). In conclusion, serum CC16 levels are markedly elevated at the early stage of pulmonary contusion and appear to decrease following treatment. An increase of the CC16 levels is associated with the degree of injury, for which measurement of the levels may serve as a biomarker for evaluation of the serious condition of this pulmonary contusion.
