AbstractMen who have sex with men (MSM) are potentially at high risk for HIV infection, their HIV prevalence far exceeds the national prevalence rate. There are also a number of MSM who have sex with women, mostly unprotected, which can transmit HIV to their female sexual partners and even to the next generation. The purpose of this article is to evaluate the prevalence of heterosexual behaviors in Chinese men who have sex with men and the status of condom utilization as well as HIV infection among MSM with heterosexual behaviors, so as to further improve the investigation and prevention and control of AIDS in MSM population. We systematically searched China National Knowledge Infrastructure, Wanfang Data, VIP Database for Chinese Technical Calligraphy (VIP), Pubmed, and Embase following certain retrieval strategies to find relevant articles published from January 1, 2015 to November 18, 2019, The useful information extracted from qualified articles, Stata 15.1 and Review Manager 5.3 were employed for further meta analysis. The estimated prevalence of heterosexual behaviors among MSM in the past year was 19.0% (95% CI 17.0%, 22.0%). The estimated condom utilization rate of the last heterosexual behavior among MSM and condom adherence rate of heterosexual behaviors among MSM were 51.0% (95% CI 44.0%, 58.0%) and 31.0% (95% CI 25.0%, 38.0%), respectively. And the pooled HIV prevalence in MSM with heterosexual behaviors was 9% (95% CI 6%, 13%). The sensitivity analysis showed that the results were stable. No publication bias was found by Egger’s test. There is a high proportion of MSM with heterosexual behaviors and low condom utilization in China. HIV prevalence in MSM with heterosexual behaviors is also high. Therefore, adequate attention should be given to this particular group and measures should be taken in order to reduce the risk of transmission of HIV from subpopulations to the general population.

Objectives. To understand the current risk of HIV infection and transmission and further elucidate the underlying risk factors among men who have sex with men and women (MSMW) in China.Methods. Following PRISMA guidelines, we conducted a systematic review and meta-analysis of searching through Chinese and English available literature databases between January 2000 and June 2014 to identify articles.Results. Thirty-six articles (including 19,730 MSMW and 53,536 MSMO) met the selection criteria and the aggregated results found that MSMW have significantly higher HIV prevalence than MSMO (6.6% versus 5.4%, OR = 1.27, 95% CI = 1.01–1.58). A higher proportion of MSMW had commercial male partners in the past 6 months (18.3% versus 12.2%, OR = 1.56, 95% CI = 1.01–2.42). Additionally, substance use in the past 6 months was significantly more frequent among MSMW than MSMO (alcohol use: 27.1% versus 13.1%, OR = 2.53, 95% CI = 2.14–2.99; illicit drug use: 5.3% versus 2.5%, OR = 2.09, 95% CI = 1.48–2.95).Conclusion. A higher proportion of commercial sex and substance use among MSMW may be a potentially indicative factor for significantly higher HIV prevalence compared to MSMO. Targeted interventions should aim at increasing the frequency of HIV/STIs screening and preventing high risk commercial sex and substance use among MSMW to decrease their HIV transmission to the general population.

BACKGROUND The HIV infection prevalence is increasing rapidly among Chinese men who have sex with men (MSM) university students, and there is limited research on the association of mobile geosocial networking (GSN) apps use and HIV-related high-risk sexual behaviour and HIV prevalence among MSM university students. OBJECTIVE To provide evidence for tailored HIV intervention programs we conducted this study to examine the association between use of GSN apps and HIV-related behaviors and HIV prevalence among Chinese MSM attending university. METHODS Chinese MSM university students were recruited using mixed recruitment methods from 2017 to 2019. Data on sociodemographic, sexual behaviours, use of GSN apps, and eligibility for pre-exposure prophylaxis (PrEP) was collected. Participants were tested for HIV and syphilis, and positive cases were confirmed by laboratory testing. RESULTS We recruited 771 MSM university students: 76.3% (n=588) online and 23.7% (n=183) offline. Among all participants, the HIV prevalence was 3.5% (n=27), and 67.4% (n=520) were eligible for PrEP. GSN app users (81.2%, n=626) vs. GSN app nonusers (18.8%, n=145) were more likely to have used recreational drugs, have multiple male sexual partners, have casual sex, and have been tested for HIV in the past six months (all P < 0.05). After adjusting for age, residence, education, and recruitment method, GSN app users had an increased odds of HIV infection compared to GSN app nonusers (aOR=8.1 [95% CI: 1.05, 62.33]). CONCLUSIONS MSM university students who used GSN apps more frequently engaged in HIV-related high-risk sexual behaviours and had a higher prevalence of HIV infection compared to GSN app nonusers. GSN app platforms can reach Chinese MSM university students and should be used to promote HIV testing and implement sexual behavioural risk reduction interventions or PrEP.

Background This study was conducted to summarise the HIV epidemic, sexual behaviours and HIV testing among men who have sex with men (MSM) attending university in China. Methods: Five databases were searched for student MSM information in English and Chinese language publications. Meta-analyses were performed to calculate the pooled prevalence of HIV and syphilis, pooled mean age at first anal intercourse (AFAI) and the rate of other HIV-related behaviours among MSM attending university in China. Univariate meta-regression and subgroup analysis were conducted to explore potential sources of heterogeneity. Publication bias was measured using Egger’s test. Results: Thirty-three articles representing 31 studies were included in the analysis. The pooled HIV prevalence was 4.1% (95% CI 3.1–5.0%). The estimated AFAI was 18.7 years, but 37.5% of students had their first anal intercourse before 18 years of age. Most (88.2%) had their first sexual intercourse with a male partner. Of the MSM attending university, 4.2% of MSM engaged in commercial sex (either selling or buying sex), 10.3% had ever engaged in group sex, 13.1% had had sex with a female partner in the past month and 10.1% had ever used drugs. Most (77.7%) sought sex partners via geosocial networking gay apps or the Internet, and 42.9% had ever tested for HIV. There was a tendency for an increase in lifetime HIV testing rate from 32% in 2005–07 to 53% in 2014–16. Conclusions: This review found high HIV prevalence, early AFAI and a high prevalence of sexual risk behaviours among MSM attending university in China. Interventions aimed at increasing HIV testing and reducing sexual risk behaviours are urgently needed among this young population.

Objective This study aimed to systematically analyze the effectiveness and safety of the local application of vancomycin powder to prevent surgical site infection (SSI) after spinal surgeries and provide guidance for clinical practice. Methods Two researchers independently searched PubMed, Web of Science, Elsevier, and China National Knowledge Infrastructure using the MeSH terms “spinal surgery,” “vancomycin,” “local,” “topical,” “prophylactic,” “surgical site infection,” and “SSI” to identify studies published between January 2010 and January 2020 on the local application of vancomycin powder for preventing SSI after spinal surgeries. The outcome assessment indicators were analyzed using RevMan 5.3 software. Results Three randomized controlled trials, two prospective studies, and 26 retrospective studies were included in the current research. The results of the meta-analysis revealed significant differences between the vancomycin and control groups (non-vancomycin group) concerning the incidence of SSI (risk ratio = 0.39, 95% confidence interval = 0.28–0.55, Z = 5.46), indicating that local application of vancomycin powder can significantly reduce the incidence of SSI. Conclusion Local application of vancomycin powder is an effective and safe method to prevent SSI after spinal surgeries.

Abstract Plenty of studies have investigated the effect of methionine synthase (MTR) A2756G polymorphism on risk of developing pediatric acute lymphoblastic leukemia (ALL), but the available results were inconsistent. Therefore, a meta-analysis was conducted to derive a more precise estimation of the association between MTR A2756G polymorphism and genetic susceptibility to pediatric ALL. The PubMed, Embase, Google Scholar, Web of Science, ScienceDirect, Wanfang Databases and China National Knowledge Infrastructure were systematically searched to identify all the previous published studies exploring the relationship between MTR A2756G polymorphism and pediatric ALL risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were applied to evaluate the strength of association. Sensitivity analysis and publication bias were also systematically assessed. This meta-analysis finally included ten available studies with 3224 ALL cases and 4077 matched controls. The results showed that there was significant association between MTR A2756G polymorphism and risk of pediatric ALL in overall population (AG vs. AA: OR = 1.13, 95%CI = 1.02–1.26, P = 0.02; AG+GG vs. AA: OR = 1.13, 95%CI = 1.02–1.25, P = 0.01; G allele vs. A allele: OR = 1.10, 95%CI = 1.01–1.20, P = 0.03). In the stratification analyses by ethnicity, quality score and control source, significant association was found in Caucasians, population-based designed studies and studies assigned as high quality. In conclusion, this meta-analysis suggests that MTR A2756G polymorphism may influence the development risk of pediatric ALL in Caucasians. Future large scale and well-designed studies are required to validate our findings.

ObjectiveTo examine the trends of HIV prevalence, risk behaviours and HIV testing among men who have sex with men (MSM) in Nanjing.DesignFive consecutive cross-sectional surveys.SettingNanjing, China.Primary and secondary outcome measuresHIV and syphilis prevalence, HIV testing rate and factors associated with HIV infection; demographic characteristics and behaviours.Results649, 669, 577, 633, 503 MSM were recruited from 2013 to 2017. HIV prevalence was 9.9%, 12.3%, 12.5%, 9.8% and 10.1%, respectively. Syphilis prevalence decreased with a range from 10.6% to 5.6%. Risk behaviours like unprotected anal intercourse (UAI) and unprotected virginal sex in the past 6 months decreased, but multiple sex partners and ever used rush popper rose significantly. MSM tested for HIV in the previous year remained stable from 57.0% to 64.1% (P=0.633). Multivariate analysis showed that tested for HIV in the past year was protective factor against HIV infection. MSM who had UAI in the past 6 months, sex role as receptive and dual, diagnosed with sexually transmitted diseases (STDs) in the past year and currently syphilis infected were risk factors for HIV infection.ConclusionsWe observed stable high HIV prevalence, a steady HIV testing rate, decreasing syphilis prevalence and UAI among MSM in Nanjing. However, rush popper use rose dramatically. The HIV preventive strategies for MSM including condom promotion, HIV testing expansion and reduction of rush popper use, STDs screening and standardised treatment should be strengthened.

HIV prevalence is still rapidly increasing among Chinese men who have sex with men (MSM). The Internet also makes it easier for MSM to have casual partners. This study aims to evaluate the trend of Internet-based sex-seeking behavior of MSM and its impact on HIV prevalence, the distribution of HIV subtype strains, and transmitted drug resistance rates. A serial cross-sectional study was conducted from 2009 to 2014. Of the 1,981 MSM, 50.5% (1,000/1,981) mainly sought homosexual partners through the Internet (Internet-based MSM, IBM). The proportion of IBM among total MSM subjects increased from 43.3% to 61.5% (p<0.001). HIV prevalence of IBM increased from 5.7% to 20.7%, while that of non-Internet-based MSM (NIBM) increased from 7.0% to 14.7%. A relative higher proportion of NIBM were infected with HIV CRF01_AE subtype than IBM (79.5% versus 72.2%, p=0.52). Multivariable analysis found IBM had a significantly higher HIV prevalence than NIBM (13.2% versus 10.5%, aOR = 1.4, 95% CI [1.0–1.9]). Being a migrant non-Shenyang resident MSM (aOR = 1.9, 95% CI [1.3–2.9]) and occasionally/never using condoms with casual homosexual partners (aOR = 1.7, 95% CI [1.1–2.6]) were two distinct risk factors for HIV infection in IBM. More efforts should be targeted towards developing interventions aimed at IBM, particularly migrant MSM and who engage in UAI with casual homosexual partners.
