Serum from RFA patients receiving GA facilitated cell proliferation of HepG2 cells after long-term, but not short-term, exposure. (A) CCK-8 assay OD values (culture time = 24h); (B) CCK-8 assay OD values (culture time = 48h); (C) mean percentage change from post- to preoperative OD value (culture time = 24h); (D) mean percentage change from post- to preoperative OD value (culture time = 48h). Values are expressed as mean ± SD. n = 11, LA group. n = 13~14, GA group. **P < 0.01. GA, General Anesthesia; LA, Local Anesthesia.
