Résumé
BACKGROUND:Neural stem cel s have multi-directional differentiation potential, self-sustaining and self-renewal capacity as wel as have strong migration ability. Bushen Huoxue Recipe can reduce neuronal damage and promote nerve cel regeneration, to achieve neural function reconstruction. Underlying mechanisms of Bushen Huoxue Recipe combined with neural stem cel transplantation in rats with tinnitus induced by sodium salicylate are yet unclear. OBJECTIVE:To investigate the effects of Bushen Huoxue Recipe combined with neural stem cel transplantation in rats with tinnitus induced by sodium salicylate. METHODS:Sixty Sprague-Dawley rats were randomized into five groups (n=12):normal control group, tinnitus model group, Bushen Huoxue Recipe group, stem cel group and combined treatment group (Bushen Huoxue Recipe combined with neural stem cel transplantation). Animal models of tinnitus induced by sodium salicylate were made in al the groups except for the normal control group. Fifteen days after modeling, rats were given intragastric administration of Bushen Huoxue Recipe water decoction (3 mL, 2.592 g/mL) for consecutive 7 days in the Bushen Huoxue Recipe group, intravenous injection of neural stem cel s (1 mL, 1.0×109/L) in the stem cel group, or their combined treatment in the combined treatment group. RESULTS AND CONCLUSION:Bushen Huoxue Recipe, neural stem cel transplantation and their combination al could effectively promote the recovery of drinking water inhibitory rate that was ranked as fol ows:combined treatment group
Résumé
OBJECTIVE@#To explore the treatment of sudden sensorineural hearing loss with steroid from different administration routes.@*METHOD@#One hundred and eighty-eight patients with diagnosis of sudden sensorineural hearing loss were selected, in accordance with the random number table, and all patients were divided into three groups. With different administration routes, they were devided into systemic steroid therapy group, intratympanic steroid therapy group and postauricular steroid therapy group,and the curative effects were collected and analyzed.@*RESULT@#The total effective rate was 78.26% in systemic steroid therapy group, 80.70% in intratympanic steroid therapy group and 80.65% in postauricularsteroid therapy group,and no statistical difference was detected among these three groups (P > 0.05).@*CONCLUSION@#The treatment of sudden sensorineural hearing loss with steroid from different adminsthation routes all can achieve a relatively favorable prognosis, and there were no obvious different among those different treatments.
