Objective To evaluate the feasibility and outcomes of robotic-assisted laparoscopic pyeloplasty in children .Methods A retrospective study was performed in patients who underwent robotic-assisted laparoscopic pyeloplasty ( Anderson-Hynes ) at our institution between January 2014 to August 2014.Totally 6 boys were diagnosed as left ureteropelvic junction obstruction depending on the symptoms and radiographic studies .The mean age was 9 years ( range 4 -12 years ) .Results The procedure was performed successfully without conversion to open surgery in all of the cases .Mean operative time was 216 min (range 175-269 min), with a mean robotic anastomosis time of 45 min (range 30-60 min).Mean estimated blood loss was less than 15 ml.The mean hospitalization was 4.5 days.Mean follow-up period was 10 months ( range 7 -14 months ) .There were no perioperative complications , and recovery was uncomplicated (without recurrence, pyelonephritis, nephrarctia) in all of the patients.Conclusion Robotic-assisted laparoscopic pyeloplasty can be safely performed in children older than 4-year-old with ureteropelvic junction obstruction .

Objective:
To understand the HIV and syphilis infection and related treatment status of low-fee female sex workers (FSWs) in 3 provinces of China.
Methods:
Four cross-sectional survey data of low-fee FSWs from six cities (counties) in Guangxi, Yunnan and Hunan Province between October 2012 and July 2015 were obtained from the national science and technology major special project intervention study for reducing sexually transmitted diseases (STDs) and acquired immunodeficiency syndrome (AIDS) in low-fee FSWs' database, which included social demographic characteristics, sexual service characteristics and related medical care seeking behaviors, etc. A total of 2 050 subjects were included in the database.
Results:
The age of the subjects was (35.16±9.76) years old, with a minimum age of 15 and a maximum age of 67. Those who use condoms every time in commercial sex accounted for 58.9% (

OBJECTIVETo study the loss to follow-up (LTF) rate, HIV emerging incidence and influencing factors in the longitudinal study of female sex workers (FSWs) in Kaiyuan, Yunnan, and their influence on HIV emerging incidence estimate.
METHODSThe open cohort study on FSWs was launched in March 2006 and ended in June 2013 in Kaiyuan, Yunnan. Investigations were made every six months and lasted for 7 years. 661 FSWs found as HIV negative in the baseline study in March 2006 were chosen to study their LTF in the 7 year follow-up investigation. The Cox regression model was used to explore risk factors for HIV emerging infection and those for LTF. In June 2013, a survey was also conducted to explore the detailed reasons for loss to follow-up by contacting FSWs themselves.
RESULTSDuring 1 238.5 person-years of follow-up among 661 HIV negative FSWs, the HIV incidence rate was 1.29 (95% CI: 0.74-2.10)/100 person-year, and the LFT incidence rate was 48.68 (95% CI: 44.88-52.73) /100 person-year. The multivariate analysis showed drug abuse as an independent risk factor for FSWs' infection of HIV (adjusted risk ratio = 4.15, 95% CI: 1.43-12.02); FSWs over 25 years old (adjusted risk ratio = 0.68, 95% CI: 0.57-0.81), and drug abuse (adjusted risk ratio = 0.52, 95% CI: 0.35-0.79) were found with lower LFT rate to remain in the cohort.
CONCLUSIONHigh LFT rate was found in FSW cohort study in Kaiyuan, Yunnan, while the HIV infection risk exposure of the LFT group was lower than the groups of HIV follow-up. HIV prevalence of FSWs in the city might be overestimated. Causes of LFT of FSWs group required further study in the future, and the cohort follow-up retention strategy for FSWs needs to be developed.
