Objective To explore the clinical effects of low-frequency (50Hz) pulse electrotherapy (LFPE) in the treatment of prostatic pelvic floor muscular spasm syndrome (PPMS), and the influence of this procedure on the temperature of rabbit urethral mucosa. Methods (1) A series of 60 cases of PPMS had undergone LFPE; (2) Thirty-six rabbits were randomly divided into 6 groups: 3 experimental groups were treated for 15 min, 30min and 50 min, respectively, while the other 3 groups served as control groups. Results All cases had been followed for (1~16) months, with a mean of 6 months. Of the 60 cases, 12 were cured, 38 improved, and 10 failed,effective rate being 83.3%(50/60). In animal experiment, there were no significant differences between the experimental and control groups on temperatures of rabbit urethral local mucosa (t=1.3306, P=0.1049). Conclusions The study demonstrates that 50Hz pulse electrotherapy may be effectively applied to PPMS.

OBJECTIVE:
To investigate the effect of dxamethasone (DEX) on the expression of Tregs in allergic rhinitis (AR) mice, and explore the mechanism of glucocorticoid in the treatment of AR.
METHOD:
AR murine model was established by sensitization and challenge with OVA, besides intervention treatment with DEX was carried out in AR model. The behavior observation was used to evaluate the improvement effect of DEX on AR symptoms. The morphological characteristics of nasal tissues were observed by HE staining after fixation and decalcification. The mononuclear cells were obtained by grinding spleens, and the total RNA was extracted for reverse transcriptase polymerase chain reaction to investigate the level of mRNA expression of Foxp3. The changes of CD4+ Foxp3+ Tcells in spleen of mice were analyzed by flow cytometry.
RESULT:
BALB/c mice received OVA sensitization followed by OVA intranasal challenge, the frequencies of sneezing and nose-scratching increased significantly in AR group (44. 50 ± 5. 61 and 72. 94 ± 8. 76) compared with control group (12. 68 ± 1. 87 and 26. 76 ± .2. 89), P<0. 01; The frequencies decreased significantly in DEX group (26. 04 ± 3. 93 and 56. 79 ± 5. 64), P< 0. 05 compared with AR group. The continuity of nasal mucosa ciliated columnar epithelium in AR group was destroyed and appeared to be repaired in DEX group. Inflammatory cells infiltration was also markedly decreased by DEX treatment. The proportion of CD4+ Foxp3+ T cells in AR group (3. 89 ± 0. 39)% decreased, P<0. 01 vs control group (4. 63 ± 0. 15) %. DEX treatment induced production of Tregs (6. 89 ± 0. 49)%, P<0. 05 vs control group. DEX significantly increased the expression of Foxp3 mRNA (P<0. 05) compared with AR and control group.
CONCLUSION
DEX reduce upper airway allergic inflammation effectively, which may be mediated by promoting the expression of Foxp3 and inducing the amplification of Tregs in vivo.

Objective To describe the single needle running suture method for the urethrovesi-cal anastomosis during laparoscopic radical prostatectomy(LRP). Methods Forty-five patients of prostate cancer underwent LRP with the single needle running suture method. The technique was initi-ated by performing a fixing suture at the posterior lip of bladder neck at 4 o' clock and tying the first knot. Another suture at the nearby position of the first suture was performed to leave the first knot outside. From 5 o' clock to 8 o' clock, sutures were performed every one o' clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were per-formed every 3 sutures. After completing the full circumference, the needle was drawn at the 2 o' clock for the second knot. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. Any remaining leakage could be closed with additional interrupted su-tures. Results All urethrovesical anastomosis were completed successfully. The mean anastomosis time was 16 rain(from 12 to 25 min), and mean operative time was 132 rain (112 to 185 rain). The mean catheterization time was 9 d(7 to 14 d). Three temporal urinary leaks requiring prolonged cathe-terization were identified. Forty-four patients had total urinary control in 1 year postoperatively and no other short-term or persistent complication was found with a mean follow-up of 21 months. Conclu- sion The single needle running suture method could be a simple and safe method for urethrovesical anastomosis during LRP.

Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P<0.05). The patients with dissected LNs counts of more than 11 for cases with pTl~2 tumor (P<0.05) and more than 16 for cases with pT3 tumor (P<0.05) had better long-term survival outcomes. The post-operative complication rate was 12.1%, which was not significantly correlated with the number of dissected lymph nodes (P>0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.

The expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder (TCCB) and its clinical significance were investigated. Immunohistochemistry was used to detect KAI1/CD82 and MRP-1/CD9 protein expression in 52 TCCB specimens. Correlation between the expression of KAI1/CD82 and MRP-1/CD9 to clinicopathologic factors was statistically analyzed. The results showed that the positive rate of KAI1/CD82 and MRP-1/CD9 in TCCB was 50% and 61.5%, respectively. The MRP-1/CD9 and KAI1/CD82 expression was significantly associated with grade of TCCB (P<0.05), but no correlation was found between MRP-1/CD9 or KAI1/CD82 expression and clinical stage of TCCB (P>0.05). The expression level of MRP-1/CD9 and KAI1/CD82 in recurrent TCCB samples was lower than that in non-recurrent samples (P<0.05). Meanwhile, the correlation between the KAI1/CD82 expression and MRP-1/CD9 expression was statistically significant (r=0.316, P<0.05). It was concluded that KAI1/CD82 and MRP-1/CD9 expression may be important prognostic indicators and potentially useful for assessing the biological behavior of TCCB.
