RESUMO
Objective To investigate the effect of early-stage training combined with the ultrashort wave therapy on the functional recovery of rats after a spinal cord injury, and to observe the expression of aquaporin pro-tein-4 ( AQP-4) and glial fibrillary acidic protein ( GFAP ) . Methods Fifty female Sprague-Dawley rats had spinal cord injury ( SCI) induced using the modified Allen's method. After successful modeling, 40 were randomly divided into a sham operation group, a control group, an ultrashort wave group, a treadmill group and a combined group, each of 8. Motor function in their hind limbs was evaluated 4 weeks after the operation using BBB scoring. GFAP and AQP-4 immunohistochemical staining were used to determine the integral optical density ( IOD) of the protein expres-sion. Results The average BBB score of the sham operation group was 21, while the other four groups averages were all less than 1 on the 1st day after the operation. They gradually increased with time, and by 4 weeks the increa-ses were significant. Compared with the control group at the same time point, the average BBB scores of the treadmill and the combined groups were significantly higher. Compared with the ultrashort wave group, the average BBB score of the treadmill group was higher after 4 weeks, and the combined group's average was significantly higher at 2, 3 and 4 weeks after the operation. Four weeks after the SCI modeling, the average AQP-4 IOD and GFAP IOD levels of the ultrashort wave group, the treadmill group and the combined group were lower than that of the control group, while the average AQP-4 and GFAP IOD levels of the combined group were significantly lower than those of the ultrashort wave group. Compared with the treadmill group, the combined group had a significantly lower average GFAP level. Conclusions Both treadmill training and ultrashort wave treatment promote motor function recovery after a spinal cord injury. The mechanism may be related to downregulation of AQP-4 and GFAP expression at the injured site. Combining the two treatments gives better effects.

RESUMO
Objective To evaluate the efficacy of bladder perfusion with sodium hyaluronate combined with ultrashort wave irradiation in bladder region in treatment of glandular cystitis.Methods 22 patients diagnosed as typical glandular cystitis were selected from our hospital between March 2013 and March 2013. Those patients were given bladder perfusion with sodium hyaluronate combined with ultrashort wave irradiation in bladder region according to the designed course. The lesion areas were taked photos and bited samples for microscopic observation and HE staining.The evaluation indicators include pelvic pain and urgency/frequency symptom scores,cystitis histologic scores ,infiltrating lymphocyte counts, Brunn nest or cystica counts and residual urine volume were measured in the self-control expertiment before treatment and after. Results Over the course of treatment, above mentioned indicators had significant improvement compared with original data among those patients (P<0.01).Only 1 patient appeared itchy skin two times after bladder perfusion with sodium hyaluronate, others without serious complications. Conclusions The method that bladder perfusion with sodium hyaluronate combined with ultrashort wave irradiation has clear effect without serious complications.This method provides a new train of thought for glandular cystitis and opens up a new space.
