Background Pain has a substantial impact on patients' activities and overall quality of life， but current conventional drugs have debilitating side effects， including gastrointestinal disorders. Thus there is a pressing need for new therapies with fewer side effects to alleviate cancer pain. We recently developed a topical herbal formula Xiaotan Tongluo analgesic gel (XTTL gel) based on the principles of traditional Chinese herbalism， and we have received positive feedback from bone cancer pain patients. The aim of this study was to determine the analgesic effects and explore the mechanisms of XTTL gel in a rat model of bone cancer pain. Methods The rat model of bone cancer pain was established by inoculating Walker-256 rat carcinoma cells directly into the right tibial medullary cavity of Wistar rats. The rats were randomly assigned to three groups (n=10 per group)： (1) sham bone cancer control (sham group)： vehicle (PBS) inoculation without carcinoma cells plus topical administration of blank gel; (2) Sham treatment control (vehicle group)： Walker-256 cell inoculation plus topical administration of blank gel; (3) XTTL gel treatment (treatment group)： Walker-256 cell inoculation plus topical administration of XTTL gel. XTTL gel treatments were applied daily for 7 days starting on day 14 following inoculation. Outcomes were assessed 21 days after inoculation by mechanical allodynia， histological staining， and by measuring concentrations of type I collagen carboxy-terminal telopeptide (ICTP) and bone-specific alkaline phosphatase (BAP) in serum. Results Fourteen days after cancer cell incubation， significant mechanical allodynia in the ipsilateral hind paw and tumor growth in proximal end of the tibia were observed in the vehicle and treatment groups but not in the sham group. At day 21， mechanical withdrawal thresholds in treatment group rats were significantly higher ((4.8557±0.8336) g) compared with those of the vehicle group ((1.8630±1.4369) g， P 0.05). Conclusion Topical use of XTTL gel may have an analgesic effect on bone cancer pain， an effect mediated by lowering of ICTP levels and inhibiting bone resorption.

Regional differences in haemoglobin values and process care measures were examined using data from the Centers for Medicare & Medicaid Services' End-Stage Renal Disease (ESRD) Clinical Performance Measures Project. It was posited that regional differences in haemoglobin values are consequent upon differences in components of clinical practice.A national random sample of 8336 adult， in-centre haemodialysis patients， stratified by the 18 regional ESRD Networks， was drawn. Information was collected for October-December 1998. Multivariable stepwise linear and logistic regression analyses were performed to identify variables associated with haemoglobin. Linear regression analysis was used to identify variables associated with Epo/Hb index (mean weight-adjusted treatment level erythropoietin (Epo) dose divided by mean haemoglobin).The percentage of patients with haemoglobin concentration < 11 g/dl ranged from 34 to 52% across ESRD Networks. In addition to haemoglobin there was significant， non-random variation among ESRD Networks with regard to prescribed Epo dose and administration route， intravenous (IV) iron prescription and dialyser flux (high flux = KUf > or = 20 ml/mmHg/h) (all P-values < 0.001). Higher haemoglobin was associated with older age， male gender， higher serum albumin， higher transferrin saturation， higher Kt/V， lower serum ferritin and lower prescribed Epo dose (all P-values < 0.01). Diabetes mellitus as cause of ESRD， high-flux dialyser use， IV iron prescription or subcutaneous Epo prescription were not associated with haemoglobin. Male gender， diabetes as cause of ESRD， older age， higher transferrin saturation and higher albumin concentrations were associated with lower Epo/Hb index. Prescription of IV iron and IV Epo were associated with higher Epo/Hb index.Regional mean haemoglobin levels vary considerably across the US and the variation in haemoglobin is explained by both non-modifiable factors and modifiable clinical practice-derived variables.

AbstractWe evaluated the impact of total prostate volume (TPV) on the international index of erectile function-5 (IIEF) and the premature ejaculation diagnostic tool (PEDT). A cross-sectional study was conducted that included 8336 men who had participated in a health examination. PEDT， IIEF and transrectal ultrasonography were used. A full metabolic work-up and serum testosterone level checks were also performed. The median age of participants was 51.0 years. In total， 40.1% had IIEF scores ≤16. Additionally， 24.7% were classified as demonstrating premature ejaculation (PE) (PEDT > 10). The severity of erectile dysfunction (ED) significantly increased with the TPV (p trend < 0.001). After adjusting for potential confounding factors， the odds ratio (OR) for IIEF scores ≤ 16 significantly increased in the group with TPVs of 30–39 cm3 and the group with TPVs ≥ 40 cm3 compared with the group with TPVs ≤ 19 cm3 (TPV 30–39 cm3， OR： 1.204， 95% confidence interval： 1.034–1.403; TPV ≥ 40 cm3， OR： 1.326： 95% confid...

Ureteral avulsion is an uncommon yet severe complication of ureteroscopy. Among 8336 patients who received ureteroscopic procedures in our hospital from December 2001 to December 2011， we encountered two cases of ureteral avulsion. The first of these experienced disruption at the ureteropelvic junction due to extraction of the tubular ureter from the urethra， which was corrected by immediate open surgery to reposition and anastomose the ureter. The second patient sustained a proximal ureteral disruption following retrieval of the ureteroscope， which was wedged in the narrow lumen of the proximal ureter， and led to simultaneous extraction of the distal ureter. Immediate surgical intervention was performed to maintain ureteral continuity. Mild hydronephrosis was observed in kidneys that were ipsilateral to the ureteral avulsion in both patients. However， no physical discomfort or loss of renal function was indicated after 12 months.
