ABSTRACT
Objective@#To understand the AIDS knowledge,attitudes and practices of freshmen in Hangzhou and to provide evidence for prevention and control of AIDS in university students.@*Methods@#Freshmen who enrolled in 2015 in a comprehensive university in Hangzhou were recruited by convenience sampling method and surveyed by a questionnaire about AIDS knowledge,attitudes and practices. Logistic regression model was used to analyze the influencing factors for awareness of AIDS knowledge among freshmen.@*Results@#There were 1 999 respondents recruited,with a response rate of 95.19%. The awareness rates of basic and extend AIDS knowledge were 97.90% and 30.67%,respectively. The results of multivariate logistic regression analysis showed that residence（OR=1.210,95%CI：1.006-1.456）,average or good family economic status（OR：1.874-3.027,95%CI：1.255-7.300）,receiving AIDS/STD related education（OR=1.717,95%CI：1.407-2.097）and receiving AIDS/STD related counselling in the past year（OR=1.786,95%CI：1.033-3.088）were the promotive factors for awareness of AIDS knowledge among freshmen. About 48.50% of freshmen thought they were impossible to be infected with AIDS,and 47.10% of them thought they were less likely to be infected with AIDS. About 0.90% of freshmen had sexual experience,fifteen,two and one of them experienced their first sex with girlfriend/boyfriend,homosexual partners and casual sex partners,respectively;nine of them used condoms in their first sex. The proportions of receiving AIDS/STD related services among freshmen ranged 2.00% from 37.77%.@*Conclusion@#The freshmen have a poor understanding of AIDS,weak awareness of HIV infection risk,high-risk behaviors for STDS/AIDS and receive insufficient AIDS prevention and intervention measures.
ABSTRACT
Objective To describe the characteristics of newly reported HIV/AIDS cases via non-marital or non-commercial heterosexual transmission and to find out the relative factors in Hangzhou,from 2015 to 2017.Methods Data were collected through the national HIV/AIDS comprehensive control and prevention data system.Study subjects would include those reported HIV/AIDS cases who were residents of Hangzhou and were infected via non-marital heterosexual transmission,between January 1,2015 and December 31,2017.Demographic characteristics and behavioral information were collected.x2 test was used to compare different characteristics of the non-married heterosexual transmission subjects.Logistic regression was used to assess factors that associated with non-marital but non-commercial HIV heterosexual transmission with SPSS.20 software used to analyze statistically.Results Non-marital HIV heterosexual transmission accounted for 38.03％ (1 393/3 663) of the total new reported HIV/AIDS cases in 2015-2017.Out of the 1 393 HIV/AIDS cases,those infected through non-marital but non-commercial heterosexual transmission accounted for 50.83％ (708/1 393),and those through non-martial commercial transmission was accounted for 49.17％ (685/1 393).Male to female ratio was 3.51 ∶ 1 (1 084/309).Male HIV cases reported that their major way of infection was via non-marital commercial transmission (670/1 084,61.81％),while female patients reported the way was via non-marital non-commercial (294/309,95.1％).Results from multivariate logistic analysis showed that the related risk factors and ORs for non-marital but non-commercial transmission appeared as:female (aOR=48.25,95％ CI:26.94-88.44),＜30 year olds (aOR=2.43,95％CI:1.3 1-4.5 1),30-39 year olds (aOR=1.92,95％CI:1.11-3.33),40-49 year olds (aOR=1.80,95％ CI:1.08-3.00),married or unmarried (vs.divorced or widowed,aOR=1.57,95％CI:1.10-2.24;aOR=1.78,95％CI:1.15-2.78),high school and above of education level (vs.primary school and under of education level,aOR=1.82,95％ CI:1.18-2.80),administrative officers or employee (vs.farmers,aOR=2.03,95％ CI:1.04-l.91).Number of non-marital partners less than 5 (vs.number of non-marital partners more than 5,aOR=10.65,95％CI:6.41-17.42).Conclusions HIV/AIDS cases with non-marital heterosexual transmission accounted for considerable proportion regarding the HIV transmission in Hangzhou from 2015 to 2017.Differences were found in the following factors as non-marital and non-commercial heterosexual transmission with diverse gender,age,marital status,educational level and occupation among of the HIV/AIDS patients.

ABSTRACT
Objective To investigate the behavioral characteristics of circadian rhythm disturbance in 3xTg-AD mice.Methods The free-running period,average activity per hour,total amount of exercise and circadian amplitude were examined with voluntary wheel-running test in 3-to 9-month-old C57BL/6 and 3xTg-AD mice under 12 h light/12 h dark cycle and constant darkness environment.Results In constant darkness environment,the free-running period in 3-month-old 3xTg-AD mice was (23.2±0.4) h,and shorter than the period((23.5±0.2) h) in C57BL/6 mice.In 6-and 9-month-old 3xTg-AD mice,activity pattern was disorganized,without clear boundary between activity and rest phase.The free-running period was unavailable.The circadian amplitude and total exercise amount were(40.6± 11.5) counts/5 min and(2.6±0.1) × 104 counts/d,(37.0±20.8) counts/5 min and(2.3±0.4) × 104 counts/d,(29.3± 11.0) counts/5 min and(1.6± 0.9) × 104 counts/d in 3-,6-and 9-month-old 3xTg-AD mice,respectively,which was significantly lower than that in age-matched C57BL/6 mice.In 12 h light/12 h dark cycle,the circadian amplitude and total exercise amount of 3-,6-and 9-month-old 3xTg-AD mice were (87.0 ± 37.8) counts/5 min and (2.2 ± 0.8) × 104 counts/d,(25.9± 6.3) counts/5 min and (1.1 ± 0.2) × 104 counts/d,(14.3 ± 5.7) counts/5 min and (0.6 ± 0.3)× 104 counts/d respectively,and with a significant decrease from the age of 6 months.Meanwhile,the locomotor activity decreased at night and increased during the day.Conclusion The endogenous circadian rhythm disturbance emerges in 3xTg-AD mice at 3-month-old,while the exogenous circadian rhythm disorder appears at 6-month-old;the degree of disorder in circadian rhythm is gradually aggravated with the increase of age in of the AD mice.
