Objective To investigate the effect of spleen-strengthening therapy contained serum on subgene P65, P50 of nudear factor-kappa B (NT-KB) and P-IκBα expression in olfactory ensheathing cells with hypoxia/reoxygenation injury. Methods Primary cultured olfactory ensheathing cells were randomly divided into five groups: normal serum control group, normal serum+hypoxia group, hypoxia+edaravone contained serum group, hypoxia+spleen-strengthening therapy contained serum group, normal serum+hypoxia+NF-KB inhibitor/antioxidant (PDTC 50 μmol/L) group....
