EA combined with passive stretch exercise can promote the recovery of the soleus and gastrocnemius muscles in disused muscle atrophy mice, which may be related to its effect in up-regulating the expression of TNNI1 and TNNI2 proteins.

To investigate the expression of apoptosis-related proteins Fas and FasL in the brain tissue of rats with traumatic brain injury and the effect of electroacupuncture on the expression of Fas and FasL, so as to explore the effective time window of electroacupuncture in the treatment of traumatic brain injury. Sprague-Dawley rats were randomly divided into blank group, sham-operation group, model group, and electroacupuncture treatment groups 1, 2, and 3. Traumatic brain injury was induced by the modified Feeney free-fall impact device, and for the rats in the electroacupuncture treatment groups 1, 2, and 3, electroacupuncture started at 4 hours and on days 3 and 7, respectively, after modeling and lasted to day 14. The Morris water maze test was used to evaluate learning and memory ability, and immunofluorescence assay and Western blot were used to observe the changes in the expression of Fas and FasL in traumatic brain tissue. Compared with the blank group and the sham-operation group, the model group helectroacupuncture treatment group 2 had significant decreases in the expression of Fas and FasL ( <0.05) on day 14 after modeling; compared with the model group, electroacupuncture treatment group 3 had significant reductions in the expression of Fas and FasL in brain tissue on day 14 after modeling ( <0.05). Early electroacupuncture intervention can regulate the apoptosis receptor pathway by down-regulating Fas and FasL to exert a therapeutic effect
