Objective To investigate the renal pelvic pressure(RPP) during minimally invasivepereutaneous nephrolithotomy(MPCNL),and inspect its influence to postoperative fever. MethodsThe RPP was measured by baroeeptor,and these data about pressure and postoperative fever wereevaluated statistically. Results The mean RPP was 14.72 mm Hg,the mean accumulative time of RPP≥30 mm Hg was 116.06 s. Fifteen cases(18. 75%)had a postoperative fever. Logistical analysissuggested that postoperative fever did not correlate to sex(P=0.195),age(P=0.641),urinary tractinfection (P=0.663),white blood cell≥10 × 109/L in blood routine examination postoperatively (P=0.751),once an occurrence of RPP≥40 mm Hg(P=0.662),while infection calculi (P=0.000),percutaneous tract size(P=0.029),mean RPP(P=0.036) ,mean RPP≥20 mm Hg(P=0.013),accumulative time of RPP≥30 mm Hg(P=0.010) and RPP≥30 mm Hg longer than 50 s(P=0.024)contributed to postoperative fever. Conclusions Renal pelvic pressure generally remains lower than alevel to back flow (30 mm Hg) during MPCNL. A transient renal pelvic pressure≥30 mm Hg don'tcountribute to postoperative fever,while a temporary high pressure status(50 s)would had an accumulated effect which means an enough back flow to bring a fever.

Objective To evaluate the clinical efficacy of endourologic treatment of benign uret-erointestinal anastomotic strictures in patients with urinary diversion. Methods Nine cases of benign ureterointestinal anastomotic strictures with a length of 1-3 cm following radical cystectomy and uri-nary diversion accepted endourologic treatment. 8 cases were treated by antegrade percutaneous ap-proach, 1 case by retrograde ureteroscopic approach. The strictures received balloon dilation, and ure-teral stents indewelled. Results In a follow up of 0.5-5.0 years, 1 case received percutaneous ne-phrostomy for complete ureterointestinal anastomotic atresia and refused to open operation reconstruc-tion. 5 cases had no recurrence after 2-3 endoscopic sessions. 3 cases needed long time ureteral stents indwelled. Conclusion Endourological technique for ureterointestinal strictures following urinary di-version avoided the disadvantages of open operation.

Objective　To evaluate the effect of Naogongfude (NGFD, a traditional Chinese medicine orally administrated) on learning and memory and the expressions of synaptophysin (SY) and Tau-protein in cerebral cortex and hippocampus in aged rats and to explore the possible mechanism. Methods　Rats were divided into normal and neural disturbance groups according to the outcomes of active avoidance reaction (AAR) test, and then each group was randomly divided into control and NGFD-treated experimental groups. Animals were orally fed with NGFD for 2 months (5 ml/d) in experimental group or routinely fed in control and taken AAR and passive avoidance reaction (PAR) tests. After the rats were sacrificed, the synaptosome count, the expression of SY and Tau-protein, and the neuron apoptosis in cerebrum were examined. Results　The rats after 2-month NGFD administration had an increased AAR acquisition, obviously delayed AAR extinction and prolonged step through latency (STL) of PAR. The number of synaptosomes was raised and the immunoreactive intensity of synaptophysin was increased remarkedly, while Tau-protein immunoreactivity and apoptotic cells were decreased in cerebrum. Conclusion　NGFD does have the effect of improving brain function and putting off the aging of rat brain according to the results of behavior study and morphological observation.

OBJECTIVETo evaluate therapeutic effect of the needle-knife closed solution combined with minor adjusting of spine for treatment of neck-shoulder syndrome.

METHODSFrom April 2010 to August 2011,120 patients with neck-shoulder syndrome were treated with the needle-knife closed solution combined with minor adjusting of spine, and included 45 males and 75 females and aged from 40 to 68 years old. The disease course was from 3 days to 10 years. After the operation, all patients taken the medicine of activating blood circulation herbs. At the 3rd, 7th, 10th day after operation, spinal rotation massage was performed on these patients. After the healing of the needle points, traditional Chinese medicine herb fumigation was applied on the needle points, and the patients were directed to do the cervical spine exercise. Therapeutic effect of the patients was evaluated by the neck disability index (NDI).

RESULTSAll patients were followed up after 3 weeks' treatment. The pain of neck-shoulder was relieved, and the range of motion was improved,the NDI score lowered from 49.30 +/- 1.35 before treatment to 10.15 +/- 1.18 at 3 weeks after treatment (t = 2.116, P < 0.05).

CONCLUSIONThe needle-knife closed solution combined with minor adjusting of spine for the treatment of neck-shoulder syndrome can relieve the pain in the neck-shoulder and improved the motion of the neck. The key for the effect is accurate location before operation, sufficient adhesion solution during the operation and spinal minor adjusting after operation.
