Objective To evaluate the efficacy and safety of solifenacin in patients with overactive bladder (OAB). Methods A multicenter clinical trial was conduced. 216 patients with OAB were enrolled. All the patients received solifenacin(5 mg once daily). With 5 weeks'treatment, all the patients recorded the diary and the adverse events as well. The symptoms of urgency, frequency, nocturia, urine volume, incontinence were evaluated. The results of the efficacy and safety were analyzed by using SPSS 13. 0. Results After 5 week treatments, all the index obviously improved(P<0.05). 187 cases (86.7%)were cured and 43 cases recovered normal voiding, 29 cases improved obviously. 11cases(5.0 %)reported adverse effect as dry mouth, dry eye. Conclusion Solifenacin could be the safe and effective drug in the treatment of OAB patients.

Objective:To study the expression of peripheral blood NKT-like cells in patients with systemic sclerosis (SSc), to explore the correlation between NKT-like cells and laboratory and clinical indicators of systemic sclerosis, and investigate the role of NKT-like cells in the occurrence and development of Systemic sclerosis.Methods:Forty-six SSc patients (SSc group) were enrolled from Department of Rheumatology and Immunology of Peking University People 's Hospital during December 2018 to December 2019. Thirty healthy subjects with matched age and sex were selected as healthy control group (HC group). The cell count and percentage of NKT-like cells and other lymphocyte subsets in peripheral blood were detected by flow cytometry. At the same time, other laboratory indexes were determined by different methods. Spearman's correlation analysis, Pearson's correlation analysis, Man-Whitney U test and Fisher's exact test were used to analyze the difference and correlation between NKT-like cells and other clinical and laboratory indicators. Results:Compared with HC group [165(72, 226)cells/μl], the cell count of NKT-like cells in peripheral blood of SSc group[30(19, 58)cells/μl] was significantly decreased ( Z=-5.69, P<0.001). Correlation analysis showed that the cell count of NKT-like cells was positively correlated with total T lymphocytes ( r=0.56, P<0.001), CD4 +T cells ( r=0.42, P=0.004), CD8 +T cells ( r=0.60, P<0.001), B cells ( r=0.50, P<0.001) and NK cells ( r=0.33, P=0.024), respectively. The percentage of NKT-like cells in lymphocytes was also positively correlated with the percentage of CD8 +T cells ( r=0.34, P=0.020), but not significantly correlated with other subset of lymphocytes. The ESR of the NKT-like cell decreased group was significantly higher than that of the NKT-like normal group[15(9, 28) mm/1 h vs 8 (4, 16) mm/1 h, Z=-2.04, P=0.042]. Moreover, the cell count of NKT-like cells was negatively correlated with ESR ( r=-0.34, P=0.019). Conclusion:The cell count and percentage of NKT-like cells in peripheral blood of SSc patients decreased significantly. NKT-like cells were not only positively correlated with a variety of lymphocyte subpopulations, but also negatively correlated with ESR. NKT-like cells may be used as an indicator to monitor the disease activity in patients with SSc.

Objective To assess the efficacy and side effects of intravesical instillation of BCG after transurethral resection of the bladder tumor (TURBT) in non-muscle invasive bladder cancer (NMIBC) patients.Methods The clinical data of patients treated with BCG 120 mg per course induced perfusion or more after TURBT from December 2013 to October 2016 in 18 hospitals of northeast China region,were analyzed retrospectively.The first part,data of 106 patients with moderate,high-risk NMIBC were collected.A total of 83 patients were male,while the other 23 patients were female.The average age was 66.7 years old.The clinical staging were T1 in 86(81.1％) cases,Ta in 20(18.9％) cases and carcinoma in situ in 6 (5.7％) patients.Intravesical instillation of BCG was executed after transurethral resection of the bladder tumor.The incidence rate of recurrence and progression during more than 6 months' follow-up time were observed.Multivariate analyses were done by using logistic analysis and Cox proportional hazards regression model with Kaplan-Meier method.The second part,treatment compliance of 276 patients with bladder cancer,including moderate/high-risk NMIBC in 263 cases,moderate/high-risk NMIBC followed with renal pelvis/ureteral carcinoma in 8 cases were and moderate/high-risk NMIBC with renal pelvis/ureteral carcinoma in 5 cases who treated with BCG after the surgeries,were observed.Patients consisted of 211 males and 65 females with average age of 68.3 years.Results With a median follow-up of 12 months,9 (8.5％) patients experienced tumor recurrence and 2 (1.9％) patients were found progression in the first part.The one-year cancer free recurrence rate of the patients was 91.5％.Statistically significant prognostic factors for recurrence identified by multivariable analyses were prior recurrence of the tumors (OR =3.214,95％CI0.804-12.845,P =0.099).In the second port,an incidence rate of adverse effects was 64.1％ (177/276).The Ⅲ/Ⅳ degree complications were occurred in 11 patients and satisfactory outcomes achieved with active treatment.A total of 36 patients withdrawal with the major causes were recurrence and progression of bladder tumor in 12 cases (4.4 ％),9 cases (3.3 ％) with economic reasons and 11 cases (4.0％) with serious complications.Conclusions NMIBC patients treated with intravesical BCG therapy have approving cancer free recurrence rates and acceptable adverse effects.Prior recurrence may be prognostic factor of recurrence after intravesical BCG therapy.

Objective:To examine the risk factors for neuropathic pain (NP) after a spinal cord injury (SCI).Methods:A total of 115 patients with a SCI were analyzed retrospectively. They were divided into an NP group of 53 and a non-NP group of 62 according to the occurrence of NP. Gender, age, length of stay, occupation, level of education, cause of injury, spinal fracture, degree of SCI, the injury′s plane and complications at admission (diabetes, hypertension, anemia, venous thrombosis, pressure sores, urinary tract infection or hypoproteinemia) were recorded. T-tests and chi-squared tests were used to compare those factors between the two groups, and multivariate logistic regressions were evaluated to identify the risk factors for NP.Results:Twenty-three of the 53 cases of NP (43%) had developed within 1 month of the SCI. Thirty-seven (75%) experienced pain below the plane of the SCI. The main features reported were squeezing (34%) and numbness (26%). The multivariate logistic regression showed that the occurrence of NP was most strongly related to gender (women being particularly at risk) and venous thrombosis at admission.Conclusions:Women are at particular risk of feeling NP after an SCI, and venous thrombosis is an independent risk factor. NP should be diagnosed and treated quickly to reduce the negative impact on patients′ life quality.

Objective:To explore the risk factors for lower extremity deep vein thrombosis (DVT) in patients with a spinal cord injury (SCI).Methods:The medical records of 276 hospitalized SCI patients were analyzed retrospectively. They were divided into a DVT group ( n=63) and a no-DVT group ( n=213). Gender, age, blood type, smoking history, surgical history, the time from SCI to admission, cause of SCI, fracture, SCI segments, American Spinal Cord Injury Association grade and complications were compared between the two groups. Binomial logistic regression was used to isolate the risk factors for lower extremity DVT among such patients. Results:Among 84% of the 63 with a lower extremity DVT, it was a calf muscle venous thrombosis. Anemia, hyponatremia and time from SCI to admission (which ranged from 74 to 195 days) were the most serious DVT risk factors.Conclusions:SCI patients are of high risk for DVT, with anemia and hyponatremia being independent risk factors.

OBJECTIVETo identify the cause of an outbreak of foot pain syndrome among students from a senior high school in Foshan.

METHODSWe defined a suspect case as onset of foot pain/numbness with unknown reason among students and teachers in a school of Foshan city, from February 10 to March 16, 2014. A suspect case was noticed as having both food pain and numbness. All the cases were searched through reviewing medical records in the nearby hospitals and school's clinic, also the records of absenteeism in school. Clinical information was collected from all the students, using a standardized questionnaire. Daily temperature was collected from all the students, between January 1 and March 31, 2014. A 1 : 2 individual matched case-control study was conducted to identify related risk factors on this epidemic. We interviewed all the cases and controls on their diet, physical activities and measures used for warming.

RESULTSA total of 407 case-students were identified, with an attack rate (AR) as 26.5%. The AR was 37.3% in girls, compared to 12.9% in boys. The difference was statistically significant (χ² = 115.1, P < 0.01). Boarding students had a higher AR (31.8%) than the commuting students (16.2%). The difference was statistically significant (χ² = 43.2, P < 0.01). In girls, boarding students had higher AR (46.1%) than those commuting students (18.5%). The difference was statistically significant (χ² = 61.4, P < 0.01). No statistically significant difference was found between boarding or commuting students in boys. Outdoor temperature was coming down from 23 °C on February 6 to 6 °C on February 13, but gradually rose to 23 °C on February 28. There was a positive relationship (r = 0.65, P = 0.002) noticed between daily maximum temperature and the number of cases during February 13-28. Results from this case-control study showed that factors as lacking physical activities (OR = 2.8, 95% CI: 1.5-5.6), feeling cold in bed (OR = 3.0, 95% CI: 1.3-7.0) and having experienced similar symptoms (OR = 3.4, 95% CI: 1.1-11.0) could increase the risk of this disease.

CONCLUSIONThis outbreak was possibly caused by the abrupt fluctuation of temperature within a short period.
