Levels of serum HMGB1, IL-1β, IL-18, and LDH at pre-RF ablation and 1 hour, 1, 2, and 3 days post-RF ablation. A. Serum HMGB1 increased immediately after RF ablation compared with preoperative levels and reduced slowly from 1-hour post-RF ablation. The peak occurred at 1-hour post procedure. B. Serum IL-1β levels were significantly elevated immediately after RF ablation compared with preoperative levels and reduced slowly from 1 hour after RF ablation. The peak of IL-1β occurred 1-hour post procedure. C. Serum IL-18 levels were significantly elevated immediately after RF ablation compared with preoperative levels and reduced slowly from 1 hour after RF ablation. The peak of IL-1β occurred at 1-hour post procedure. D. Serum LDH increased immediately after RF ablation compared with preoperative levels and reduced slowly from day 2 after RF ablation the peak occurred at 1-day post procedure. *P < 0.05, **P < 0.01, ***P < 0.001, NS = not significant.
