Comparison of MMSE and MoCA scores, S-100β protein level in group C, group S, and group S + MP. MMSE and MoCA scores were used to assess the cognitive function at the day before operation (Ts), the first (Tb), third (Tc), and seventh (Td) day after operation, and S-100β protein level was used to reflect the level of brain injury at 10 min before anesthesia (Ta), the first (Tb), third (Tc), and seventh (Td) day after operation in different groups. a and b: MMSE and MoCA scores in different groups. Compared with Group C at Tb, Tc, and Td, #P <0.05 in group S; Compared with Group S at Tb, Tc, and Td, *P <0.05 in group S + MP. c: S-100β protein level in different groups. Compared with Group C at Tb, Tc, and Td, #P <0.05 in group S; Compared with Group S at Tb, Tc, and Td, *P <0.05 in group S + MP. Data are representative of 30 independent experiments
