Abstract:

BACKGROUND:C-reactive protein has been shown to rapidly increase during the occurrence of inflammation and tissue injury, and can indicate the degree of inflammatory reaction.

OBJECTIVE: To analyze the correlation between survival time and C-reactive protein in rabbits after transplantation of polytetrafluoroethene artificial trachea with support ring.
METHODS: The cervical trachea of rabbits was replaced by polytetrafluoroethene artificial trachea with support ring. Survival time of the rabbit, and the changes in serum C-reactive protein at 1-7 days after transplantation were observed. Linear regression was used to assess the univariate association between serum C-reactive protein and survival time.

RESULTS AND CONCLUSION: The linear correlation was observed between changes of serum C-reactive protein and survival time in rabbits with artificial trachea replacement operation. C-reactive protein levels in rabbits with < 13 days of survival time were increased and positively associated with the number of days after transplantation. However, C-reactive protein levels in rabbits with > 13 days were decreased and negatively associated with the number of days after transplantation. In rabbits with positive correlation and negative correlation, the median survival time and 95% confidence interval (CI) were respectively 10 days (95%CI 8.614-11.386 days) and 27 days (95%CI 23.970-30.030 days). The survival rate in negative correlation group was significantly higher than positive correlation group (x2 =29.364, P < 0.01). Results suggested that the prolonged survival time of rabbits after artificial trachea replacement operation was related to the decreased concentration of serum C-reactive protein.
