Effects of Yunnan Baiyao aerosol and Tuina rolling on changes of NF⁃κB signaling pathway and inflammatory factor in acute stage of skeletal muscle injury in rabbits
Objective,2,By observing the NF-κB signaling pathway and inflammatory factor-related indexes, the effects of Yunnan Baiyao aerosol and Tuina rolling on the repair of skeletal muscle in rabbits in the acute stage of skeletal muscle injury were analyzed, and the mechanism of the action on skeletal muscle injury repair was explored.,Methods,2,Totally 32 New Zealand rabbits were randomly divided into blank group, model group, Tuina rolling group and Yunnan Baiyao group, with 8 rabbits in each group. Each group were further randomly divided into 2 subgroups (corresponding to 24 h and 72 h after injury), with 4 rabbits in each subgroup. Except the blank group, the rabbits in the other groups were molded with a gravity hammer, and the homemade massager and Yunnan Baiyao aerosol were respectively used to treat the rabbits for three days at 24 h and 72 h after injury. Local damaged tissue was observed by hematoxylin-eosin (HE) staining 24 hours after treatment. The contents of TNF-α and IL-1β in the damaged tissues were detected by enzyme linked immunosorbent assay (ELISA), and the contents of NF- κB p65 protein and nuclear factor κB inhibitor protein α (IκBα) in the damaged tissues were detected by Western blot.,Results,2,①The results of HE showed that compared with the blank group, the model group had inflammatory infiltration and serious muscle injury, indicating that the model was successful. Compared with the model group, the muscle fibers were seriously broken and the neutrophils were widely released in the 24 h Tuina rolling group. Compared with the model group, the injury degree in 24 h and 72 h Yunnan Baiyao groups and in 72 h Tuina rolling group was lighter, the number of inflammatory cells was reduced, and the muscle cells were arranged in a cylindrical shape. ②The results of ELISA showed that compared with the blank group, the contents of TNF-α and IL-1β in the whole tissue of the model group increased (,P,<,0.05). Compared with the model group, the contents of TNF-α and IL-1β increased in 24 h Tuina rolling group, but decreased in 72 h Tuina rolling group (,P,<,0.05). Compared with the model group, the contents of TNF-α and IL-1β in Yunnan Baiyao group decreased at each time point (,P,<,0.05). ③The results of Western blot showed that compared with the blank group, the expression of NF-κB p65 protein increased and the content of inhibitor protein IκBα decreased at each time point in the model group (,P,<,0.05). Compared with the model group, the expression of NF-κB p65 protein decreased significantly, but the expression of IκBα increased in 72 h Tuina rolling group, and NF-κB p65 protein decreased significantly and IκBα protein increased significantly in 24 h and 72 h Yunnan Baiyao group (,P,<,0.05).,Conclusions,2,Yunnan Baiyao aerosol can down-regulate TNF-α and IL-1β, inhibit NF-κB signal transduction, reduce apoptosis of skeletal muscle injury cells, inhibit inflammatory release, and promote skeletal muscle function repair in 24 h and 72 h after muscle tissue injury, especially in the acute stage of skeletal muscle injury. But the Tuina rolling method has those effects only in 72 hours after muscle tissue injury.
