Objective:
To investigate the prevalence and influencing factors of repeated HIV antibody tests among men who have sex with men (MSM) in Wuhan City, so as to provide insights into the development of interventions against AIDS among MSM.
Methods:
MSM with self-reported homosexual behaviors in a community studio in Wuhan City were recruited using a convenient sampling method from January to April 2019, and participants' demographic features, sexual behaviors, HIV antibody tests and recognition of HIV antibody tests were collected using questionnaires. Factors affecting repeated HIV antibody tests were identified using a multivariable logistic regression model.
Results:
Totally 300 valid questionnaires were recovered, with a mean age of (31.06±10.24) years. Among all the participants, 196 participants had the first homosexual behaviors over 18 years of age (65.33%), 107 participants were insertive partners (35.67%), and 125 participants received sex-transmitted diseases (STDs) tests in the past six months (41.67%). The mean score for recognizing the risk of HIV infection was 12.41±3.09, for HIV antibody test self-efficiency was 17.07±2.12, and for perceived social supports was 17.42±2.41. A total of 287 respondents received HIV antibody tests (95.67%), including 192 participants receiving repeated HIV antibody tests (64.00%). Multivariable logistic regression analysis showed that age of >18 years for the first homosexual sex behavior (OR=0.404, 95%CI: 0.223-0.734), receiving STDs tests in the past six months (OR=3.896, 95%CI: 2.145-7.076), sex role as receptive partners or both receptive and insertive partners (OR=0.502, 95%CI: 0.275-0.917), satisfying with HIV antibody test services (OR=2.955, 95%CI: 1.311-6.660), and high score for HIV antibody test self-efficiency (OR=1.149, 95%CI: 1.005-1.314) were factors affecting repeated HIV antibody tests among MSM.
Conclusions
The detection of repeated HIV antibody tests was 64.00% among MSM in Wuhan City in 2019, and age for the first homosexual behavior, STDs tests, sex role, evaluation of HIV antibody test services and self-efficiency of HIV antibody tests may be factors affecting repeated HIV antibody tests among MSM.

Objective To evaluate the changes of left ventricular regional function in normal subjects with aging and the influencing factors by Doppler tissue imaging. Methods One hundred and twelve normal subjects were divided into four groups according to age: I group with age≤18 years old ; II group with 18 60 years old. Using a quantitative tissue velocity analysis system and tissue tracking, the peak velocities of different ventricular segments at systole, early and late diastole (Vs, Ve,Va) , the Ve/Va ratios were obtained and the effects of age, gender, heart rate and STd were analyzed. Results (1) Peak velocities of different segments of each wall were decreased one by one from mitral annulus, the basal, middle segment to the apical portion. (2) Peak velocities of different ventricular walls were significantly different, with the antero- and posterio-inter-ventricular septum being the lowest CVe (6. 89?2. 60) ,(7. 94?2. 64)cm/s]and with the latero-,posterio-,antero, and inferior walls of the left ventricle being higherCVe (9. 85?3. 02) , (9. 80?3. 09), (8. 86?3. 16), (8. 23?2. 48) cm/s] . (3) Peak velocities of different segments were associated with age, STd, BMI, heart rate and not associated with gender. (4) The Ve/Va ratios were increased one by one from mitral annulus, basal, middle segment to apical portion, and were significantly lower in III group and IV group than in I group and II group. Conclusions Peak velocities of different segments at different walls change regularly and age is the most important influencing factor to the diastolic velocities.

Objective:
To learn the knowledge, attitude and behaviors of AIDS of men who have sex wth men ( MSM ) in a gay bathhouse, so as to provide evidence for AIDS prevention and control among MSM.
Methods:
From April to June of 2017, the MSM in a gay bathhouse in Wuhan were investigated. Demographic information, awareness of AIDS related knowledge, attitude towards HIV infection, dating ways and purposes, and high-risk sexual behaviors were collected and analyzed.
Results:
Among 278 MSM responded, 235 ( 84.53% ) were aware of the basic knowledge of AIDS. The awareness rates of " transfusion with HIV blood will be infected ", " sharing syringes with HIV infected people will be infected ", "proper use of condoms can reduce the spread of AIDS ", " only having sex with one partner ( or few partners ) can reduce the spread of AIDS " were more than 90%, while the awareness rate of " high risk of HIV infection in gay bathhouses " was only 56.12%. Most respondents cared about the HIV infection situation of MSM, accounting for 74.46% ( 207 cases ) ; most denied or did not know the condition of friends infected with HIV, accounting for 82.37% ( 229 cases ) . The main purpose of coming to gay bathhouses was to find sexual partners, accounting for 87.41% ( 243 cases ) . About 52.16% had sexual behaviors with both heterosexual and homosexual partners, and 66.21% of them did not often or never use condoms when having sex with heterosexual partners.
Conclusions
The MSM in a gay bathouse have lower awareness of HIV infection situation and their partners, both heterosexual and homosexual behaviors, and lower proportion of insisting on condom use.

OBJECTIVE To assess the efficancy of Yangxue Qingnao granules on simvastatin-induced vascular injury model in zebrafish. METHODS Since statins can inhibit vascular development in zebrafish,in this study,we developed a novel animal model using 1 to 3 day post-fertilization larval zebrafish by optimizing the doses and duration of simvastatin exposure.Five pro-angiogenic drugs with a variety of mechanisms were tested to validate the newly developed zebrafish model. Zebrafish was treated with different concentration of Yangxue Qingnao granules( 62.5,125 and 250 μg·mL-1)for 2 d then tested for the area of subintestinal vein vessels. RESULTS Vascular regeneration promoting effect of five pro-angiogenic drugs (calycosin, astragaloside, chlorogenic acid, ferulic acid and Panax Notoginseng Saponins)were 8-48%,24-51%,35-58%,28-75% and 37-69%,respectively.In 62.5,125 and 250 μg·mL-1Yangxue Qingnao granules group,vascular regeneration promoting effect were 21% (P>0.05), 84%(P<0.01) and 53%(P<0.01). CONCLUSION Our results demonstrate that the zebrafish vascular injury model validated in this study could be used for in vivo angiogenesis studies and drug screening and for assessing pro-angiogenic drugs with different mechanisms.Yangxue Qingnao granules could promote the vascular regeneration in zebrafish.

Objective To explore the optimal cut-off points of body mass index(BMI),percentage of body fat(PBF) and body fat mass index(BFMI) for identification of cardiovascular risk factors clustering among elderly males. MethodsThe data of physical examinations from 1 052 Shanghai elderly males in 2007 were collected.The relationship between cardiovascular risk factors clustering and different strata of BMI,PBF and BFMI was analyzed.Receiver Operator Characteristic(ROC) curve analysis was employed to determine the optimal cut-points for identification of cardiovascular risk factors clustering,and area under curve(AUC) was worked out.The population attributable risk proportion(PARP) of risk factors clustering was calculated. Results Odds ratios of risk factors clustering tended to increase with BMI,PBF and BFMI.BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 were the cut-off points that had approximate sensitivity and specificity,and/or had the shortest distance in ROC curve.AUC of all the three indexes was larger than 0.5.Analysis of PARP indicated that BMI under 24 kg/m2,PBF under 21% and BFMI under 5 kg/m2 could prevent 27.1%,37.44% and 36.63% risk factors clustering,respectively. Conclusion BMI≥24 kg/m2,PBF≥21% and BFMI≥5 kg/m2 can well reflect the cardiovascular risk factors clustering among elderly males.

?AIM: To investigate the changes of nearwork induced transient myopia ( NITM ) in different refractive status after continuous near tasking.?METHODS:Prospective study. Thirty subjects ( aged 18-24, average 20. 9 ± 2. 1, 12 males and 18 females) were recruited in this study. They were divided into 3 groups according to the subjective refraction: 10 with hyperopia (H), 10 with emmetrope (E) and 10 with myopia (M). All the subjects with soft contact lens watched videos on a panel computer at near distance (33cm ~ 40cm). Five measurements of distance refraction in the right eye were performed by using an infrared optometer before, after 30min and 60min sustained viewing task, and the mean of 5 refractive values was recorded as spherical equivalent. Then distance refraction of right eyes was done every 5s followed by stopping near tasking until NITM was disappeared completely and the decay time of NITM was recorded for each subject. The value of NITM was the difference of refractive values between before and after near tasking. Paired-t test was used to compare the changes of refractive values in the same group. ANOVA was used to determine the differences of NITM and its decaying time among three groups.?RESULTS: Compared with pre - task, no significant refractive changes were found in hyperopic group ( t =1. 627,P= 0. 138 ); While subjects with emmetropia and myopia showed more myopic shifts at the two time points (tE = 2. 699, PE = 0. 024;tM = 4. 930, PM = 0. 001 ). With continuous viewing until the 30th min and 60th min, significant differences of averaged NITM were found between myopic group and other 2 groups (P<0. 05), but no difference was found between hyperopic group and emmetropic group (P>0. 05). Significant differences of the decay time of NITM can be seen among the three groups after near tasking (F=787. 983,P<0. 001).? CONCLUSION: Subjects with myopia are more susceptible to produce NITM than other 2 groups during sustained nearwork for the same time and the decaying time of NITM is longer in myopia group after near tasking, thus it is suggesting that NITM might be attributed to the development and progression of myopia.
