Inflammatory factors in both groups. Compared with group VCV, concentration of NE in group PCV-VG was significantly different, at T4 has a significantly decreased (P=0.01). Compared with T1, concentration of NE other time points in each group were statistically different (P=0.01). There was no significant difference in TNF-α, and IL-8 between two groups (P=0.76, P=0.35). But compared with T1, concentration of TNF-α, and IL-8 other time points in each group were statistically different (P=0.01). There was no significant difference IL-6 between two groups (P=0.55). But compared with T1, concentration of IL-6 T4 points in each group were statistically different (P=0.01). T1 – one-lung ventilation 0 min; T2 – one-lung ventilation 30 min; T4 – 5 min after chest closure.
