The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.
