Objective To explore the efficacy of retropubic midurethral synthetic sling(RMUS)in relieving urgency and urge urinary incontinence(UUI)symptoms in patients with mixed urinary incontinence(MUI).Methods Clinical data of 44 female MUI patients treated with RMUS during Jan.2018 and Dec.2020 in Shanghai Renji Hospital were retrospectively analyzed.All patients had positive results in stress test and Marshall-Marchetti test before operation,and 27 of them completed ICIQ-FLUTS-LF questionnaire.Urodynamic(UDS)tests suggested that 9 patients(20.5％)presented detrusor overactivity(DO).During RMUS procedure,the tension of the sling was adjusted based on the anatomical landmarks.The postoperative efficacy and improvement of urinary incontinence were analyzed.Results The patients aged(58.59±9.08)years,with a body mass index of 24.71±2.77.Among the 40 patients who completed telephone interview 2 years after surgery,the subjective cure rate was 85.0％(34/40).Among the 27 patients with records of questionnaires before and after surgery,there were significant differences in the incidence of urine leakage[100％(27/27)vs.18.5％(5/27)],stress urinary incontinence(SUI)[100％(27/27)vs.18.5％(5/27)]and UUI[70.4％(19/27)vs.29.6％(8/27)](P＜0.05).However,no statistical differences were found regarding nocturia voiding episode(≥1 times),urgency,dysuria,hesitancy,strain to void,intermittent stream and enuresis(P＞0.05).Based on preoperative UDS test,there were significant differences regarding the subjective cure rate in patients with or without preoperative DO[55.6％(5/9)vs.93.5％(29/31)],incidence of SUI[66.7％(4/6)vs.4.8％(1/21)],and UUI[66.7％(4/6)vs.19.0％(4/21)](P＜0.05),while there was no statistical difference regarding urgency[66.7％(4/6)vs.33.3％(7/21)](P＞0.05).Conclusion RMUS is effective in treating MUI patients with positive stress test and Marshall-Marchetti test results,which can relieve SUI and UUI symptoms,but has no effects on urgency symptoms.DO on preoperative urodynamics results in poorer subjective outcomes.

Objective:To analyze the epidemiological and clinical characteristics of respiratory syncytial virus (RSV) infection in children in Jiangsu Province from 2014 to 2023.Methods:The acute respiratory infection cases in children aged 0-14 years were selected from outpatient/emergency or inpatient departments in 2 surveillance sentinel hospitals, respectively, in Nanjing, Suzhou and Taizhou of Jiangsu from 1 July 2014 to 31 December 2023, and RSV nucleic acid test was conducted and the intensity of the RSV infection was accessed by WHO influenza epidemiological threshold method, and case information and clinical data were collected. χ2 test was used to compare the differences between groups, and the Bonferroni method was used for pairwise comparisons between groups. Results:In 4 946 cases of acute respiratory infections, the RSV positive rate was 8.21% (406/4 946), and the age M( Q1, Q3) of the cases was 1 (0, 3) years. The RSV positive rate was 10.92% (258/2 362) during 2014-2019 and 6.06% (118/1 948) during 2019-2023, the difference was significant ( χ2=31.74, P<0.001). RSV infection mainly occurred from October to March during 2014-2019, with the incidence peak in December and moderate or higher intensity. The seasonality of RSV infection was not obvious during 2019-2023, with low intensity. The RSV positive rate was highest in children in age group 0- years (17.85%, 151/846), and the positive rate declined gradually with age ( χ2=184.51, P<0.001). The RSV positive rate was higher in inpatient cases (9.84%, 244/2 480) than in outpatient/emergency cases (6.57%, 162/2 466) ( χ2=17.54, P<0.001). In the 155 RSV infection cases with complete clinical data, the clinical symptoms mainly included cough (99.35%, 154/155), fever (55.48%, 86/155), and shortness of breath (45.16%, 70/155). In the cases aged <6 months, the proportion of those with fever was low, but the proportion of those with shortness of breath, transferred to intensive care units, and receiving oxygen therapy were higher (all P<0.05). Children aged <6 months and those with underlying diseases were more likely to have severe RSV infection (all P<0.05). Conclusions:RSV infection in children in Jiangsu Province showed seasonal prevalence in winter from 2014 to 2019. Since 2020, the seasonal characteristics of the epidemic have changed, the epidemic period has been dispersed and the epidemic intensity has decreased. Infants <1 year old were at high risk for RSV infection, and those <6 months old and with underlying diseases might have severe infection.

[Objective] To explore the application of pelvic floor ultrasonography in the treatment of mixed urinary incontinence (MUI) by transvaginal retropubic midurethral synthetic sling (RMUS), in order to understand the relationship between the morphological changes of pelvic floor structures and the efficacy of RMUS. [Methods] Clinical data of 44 female MUI patients undergoing RMUS during Jan.2018 and Dec.2020 were retrospectively analyzed.Urodynamics detected detrusor overactivity (DO) in 9 cases (20.5%). During RMUS procedure, the tension of the sling was adjusted based on the anatomical landmarks. The changes of ultrasonic parameters before and after operation, the relationship between the ultrasonic results, surgical efficacy and urodynamic results were analyzed. [Results] The patients averaged (58.59±9.08) years, with the body mass index being 24.71±2.77.The subjective cure rate was 91.3% (21/23) 3 months after surgery, and 85.0% (34/40) 2 years after surgery.Pelvic floor ultrasonography showed significant differences in posterior urethravesical angel at rest and during Valsalva, bladder neck descent distance and the rate of urethral funneling during Valsalva (P<0.05). According to the group analysis of the preoperative ultrasonic results, there was no statistical significance in the subjective cure rate between the funneling group and the non-funneling group during Valsalva, and the bladder neck non downward group/mild downward group/moderate downward group/severe downward group during Valsalva 3 months and 2 years after surgery (P>0.05). At 3-month follow-up, all pre-RMUS urethral funneling during Valsalva disappeared in patients without preoperative DO.Comparatively, 50.0% (3/6) urethral funneling still presented in DO patients, who had a lower cure rate (55.6%, 5/9) at the 2-year follow-up. [Conclusion] RMUS can reduce the posterior urethravesical angel at rest and during Valsalva, reduce bladder neck descent distance and the rate of urethral funneling during Valsalva in MUI patients, which can enhance urinary continence.There seems to be a correlation between DO and urethral funneling during Valsalva, while RMUS may potentially reverse the two markers.

Objective:To investigate the survival rates of patients with liver cancer in Shanghai from 2002 to 2013. Methods:Data on new cases and deaths of liver cancer patients withfollow-up information from 2002 to 2013 were obtained from the Population-Based Cancer Registry and Vital Statistics System of the Shanghai Municipal Center for Disease Control and Prevention.Incidence and survival rates were stratified by year of diagnosis,gender,district,age-group and stage at diagnosis for analysis.Statistical indicators,such as case numbers,proportions,median age and mean age were calculated.The 1-to 5-year observed survival rates were calculated based on the life table method.The probabilities of surviving from 0 to 99 years old were estimated with the Elandt-Johnson model,and then cumulative expected survival rates were calculated using the Ederer Ⅱ method.Finally,the 1-to 5-year relative survival rates were calculated. Results:A total of 49 455 new cases of liver cancer were diagnosed from 2002 to 2013 in Shanghai,including 35 115 males and 14 340 females.The ratio of males to females was 2.45:1.The proportions of stage Ⅰ,stage Ⅳ and stage unknown were 3.32％,13.93％and 69.13％,respectively.The median survival time of patients with liver cancer diagnosed from 2002 to 2013 was 0.77 years,the 5-year observed survival rate was 13.23％,and the 5-year relative survival rate was 14.47％.According to the 5-year observed survival rate and 5-year relative survival rate of the cases,both survival indicators were higher in urban areas than in suburban areas,higher in males than in females,higher in cases under 45 years of age than in those over 75 years of age,higher in cases diagnosed from 2011 to 2013 than those diagnosed from 2002 to 2004.Additionally,the survival rate of cases decreased with increasing stage at diagnosis. Conclusion:With the continuous improvement of the diagnosis and treatment of liver cancer in Shanghai,the survival rate of patients with liver cancer has shown a significant upward trend over time.However,compared with various malignant tumors such as gastric cancer and breast cancer,the improvement effect of liver cancer survival rate is still not significant.Additionally,a high proportion of cases with unknown clinical stage at the time of diagnosis and a low survival rate of stage Ⅳ cases were observed.This study provides a basis for the prevention and research of liver cancer.

Objective: To investigate the prevalence of adolescents dietary behavior in Shanghai, and to explore emotional influence on dietary behavior. Methods: A total of 7 456 students from 10 junior and 6 senior high schools in Shanghai were selected to participate in the questionnaire survey with the stratified random cluster sampling method. The survey included general information, eating behavior, PHQ-2 and GAD-7. Results: During the past week, the proportion of adolescents in Shanghai reported consumption of sugar sweetened beverages, sweet desserts, frequent fried food and fast food (≥4 times/week) were 13.26%, 16.90%, 6.99 % and 13.01%, respectively. The proportion of students reported consumption of fruits, vegetables, milk and breakfast every day were 56.96%, 73.00%, 65.03% and 76.11%, respectively. There were significant differences by sex and educational stages(both P <0.05). Adolescents with depression or anxiety have a higher incidence of unhealthy eating behaviors than those without depression or anxiety( P <0.01). After adjusting for gender, school, accommodation, grades, pocket money and social class, depression and anxiety increase the risk of various unhealthy eating behaviors in adolescents( P <0.05). Compared with those without anxiety, the risks of sugar sweetened beverages consumption (≥1 time/d) among adolescents with mild and moderate to severe anxiety were 1.42 times (95% CI =1.20-1.67) and 2.51 times (95% CI =2.09-3.01), the risks of insufficient fruits consumption (<1 time/d) were 1.30 times (95% CI =1.16-1.45) and 1.28 times (95% CI =1.11-1.47), the risks of insufficient vegetable consumption (<1 time/d) were 1.35 times (95% CI =1.20-1.52) and 1.41 times(95% CI =1.21-1.65), the risks of insufficient milk consumption (<1 time/d) were 1.29 times (95% CI =1.15-1.44) and 1.20 times(95% CI =1.04-1.39), and the risks of breakfast skipping were 1.75 times (95% CI =1.54-1.99) and 2.97 times (95% CI =2.55-3.46) among adolescents with mild and moderate to severe anxiety. Conclusion The proportion of unhealthy eating behaviors among adolescents in Shanghai is still high. Early education and intervention for students eating behaviors should be carried out, and attention should be paid to the occurrence of adolescents negative emotions, so as to reduce the risk of unhealthy eating behaviors among adolescents through the promotion of mental health.

OBJECTIVETo study in vitro and in vivo protein expression and biological function of gene pp1158, a hepatocellular carcinoma (HCC)-related gene.

METHODSpp1158 was expressed with fusion expression vector pET-32a in E. Coli-BL21 (DE3), and rabbit anti-pp1158 fusion protein polyclonal antibody was prepared. The biological function and differential expressions of pp1158 were studied by in vitro colony formation assay nude mouse in vivo tumor formation assay of transfected BEL7402 cell line and immunohistochemistry and Western blot. Differential expression of pp1158 in human fetal tissues were examined by Northern blot.

RESULTSIn vitro experiment showed that pp1158 inhibited colony formation rate of transfected BEL 7402 cells, with an inhibition rate of 58.3% (P < 0.01). Tumor formation assay indicated that tumor formation of pCMV-Script-1158 transfected BEL 7402 cell line was significantly inhibited (P < 0.05) as compared with that of the control group. Immunohistochemical assay showed that pp1158 was expressed in human tissue in the following sequence: normal liver >/= noncancerous liver tissue > HCC. Western blot indicated that a 60kD protein (pp1158 protein) was expressed in BEL 7402 cells transfected with pCMV-Script-pp1158 DNA, while it was detected in BEL 7402 cells transfected with pCMV-Script vector DNA. Northern blot showed pp1158 was expressed in the placenta at a very high level, heart, liver, muscle, pancreas and lung but expressed poorly in the brain and kidney.

CONCLUSIONpp1158 is a new candidate tumor suppressor gene of HCC.
