Expression levels of apoptosis-associated proteins in lung tissues in the three study groups, the sham group, the model group, and the dexmedetomidine-treated group determined by Western blot. (A) In the model group, the expression of caspase-3 (B) in the lung tissues is significantly higher than that in the sham group and the dexmedetomidine-treated group, while Bcl-2/Bax (C) are significantly lower compared with the sham group and the dexmedetomidine-treated group. ** P<0.01 compared with the model group, ^## P<0.01 compared with the sham group.
