Evaluation of expression of inflammatory cytokines and COX2 with the treatment of PCL, PCL/2% celecoxib nano fibers, and PCL/6% celecoxib nano fibers. a–f IHC results of TNF-α (a, b), IL-1β (c, d), and COX2 (e, f) in NP of rabbits treated with PCL, PCL/2% celecoxib, and PCL/6% celecoxib nano fibers for 6 weeks and 12 weeks. *P < 0.05 compared with the puncture group, ^#P < 0.05 compared with the puncture + PCL group, and ^†P < 0.05 compared with the puncture + PCL/2% celecoxib group
