Objective To explore the effect of back Tuina on motor behavior,oxidative stress and in-flammation in rats with chronic fatigue syndrome(CFS).Methods Twenty-four Sprague-Dawley rats were randomly divided into a blank group,a model group and a Tuina group,each of 8,according to a random number table.The CFS rat model was prepared by means of forced weight-bearing swimming combined with chronic stress stimulation in 21 days.After modeling,the Tuina group was given daily 20-minute Tuina for 14 days.The general condition semi-quantitative score,exhaustion swimming time and open field experiment(OFE)distance of all groups were recorded.After the experiment,sam-ples were collected,and the histopathological changes of the vertical spine muscles were observed by hematoxylin and eosin(HE)staining.The cross-sectional area and diameter of muscle fibers were calcu-lated using Image Pro Plus software,and the frequency distribution diagram of cross-sectional area of muscle fibers was processed by using the Origin software.The contents of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and peroxisome proliferator-activated receptor γ-coactivator 1α(PGC-1α)and tumor necrosis factor(TNF)-α,interleukin(IL)-1β,IL-6 in the serum of rats were mea-sured.Results After the intervention,the general condition semi-quantitative score of the Tuina group was significantly lower than the model group(P<0.01),while the exhaustion swimming time and OFE distance were significantly higher than the latter group(P<0.05,P<0.01).(2)HE staining showed that the significant atrophy of erector spinal muscle cells in the model group,was significantly relieved in the Tuina group.(3)Compared with the blank group,the contents of SOD,GSH-Px and PGC-1α in erectus muscles decreased significantly(P<0.01),while those of TNF-α,IL-1β and IL-6 in the se-rum of the model group increased significantly(P<0.01).However,compared with model group,the contents of SOD,GSH-Px and PGC-1α in erectus muscle increased significantly(P<0.05,P<0.01),while those of TNF-α,IL-1β and IL-6 of the Tuina group decreased significantly(P<0.05,P<0.01).Conclusion Tuina in the back can regulate the oxidative stress response,reliever the inflammatory re-sponse and improve the motor behavior of CFS rats.
