mtDNA levels in serum were detected by quantitative PCR and calculated using the 2^–ΔΔCT method, where CT represents cycle threshold value (n = 10). mtDNA. Mitochondrial DNA; SB. Sham burn; BN. Burn in normoxia condition; BH. Burn in hypoxia condition; BHD. Burn in hypoxia condition with DNase I treatment. Results are presented as mean ± SD. ^*P < 0.01 vs. SB group; ^#P < 0.01 vs. BN group; ^△P < 0.01 vs. BH group
