BACKGROUND A number of molecular epidemiological studies have been conducted to explore the association of human papillomavirus (HPV) infection with laryngeal cancer. However, the findings are heterogeneous. METHODS We systematically reviewed studies on HPV infection and laryngeal cancer published up to 15 May 2012 and quantitatively summarized the(More)
Specific risk behaviors related to different sexually transmitted infections have not been widely evaluated among men who have sex with men in China. In the present study, a total of 302 MSM were recruited from Beijing with a prevalence of HIV, syphilis, and anal HPV infection as 9.9, 19.2 and 71.4%, respectively. Lower education level was observed to be(More)
BACKGROUND In light of China's unique ethnic and sociocultural context, and a marked rise in HIV prevalence among MSM, it is important to determine prevalence, genotypes and predictors of anal human papillomavirus (HPV) among HIV-infected and uninfected men who have sex with men (MSM) in Beijing, China. METHODS In 2010-2011, we recruited MSM (age range(More)
BACKGROUND Genetic polymorphism is suggested to be associated with human physical performance. The angiotensin I-converting enzyme insertion/deletion (ACE I/D) polymorphism and the α-actinin-3 gene (ACTN3) R577X polymorphism have been most widely studied for such association analysis. However, the findings are frequently heterogeneous. We aim to summarize(More)
BACKGROUND Prophylactic treatment of individuals with latent Mycobacterium tuberculosis infection is an essential component of tuberculosis control in some settings. In China, the prevalence of latent tuberculosis infection, and preventive interventions against this disease, have not been systematically studied. We aimed to assess the prevalence of latent(More)
BACKGROUND Association studies have been employed to investigate the relationships between host single nucleotide polymorphisms (SNPs) and susceptibility to pulmonary Tuberculosis (PTB). However, such candidate genetic markers have not been widely studied in Chinese population, especially with respect to the disease development from latent M. tuberculosis(More)
BACKGROUND In the recent years, dramatic increases in HIV transmission among men who have sex with men (MSM) have been observed in China. Human papillomavirus (HPV) infection related anal cancer is more common among HIV-infected MSM as compared to the general population. However, HPV infection and anal cytology has been rarely studied in HIV-infected MSM in(More)
BACKGROUND Men who have sex with men (MSM) were found to be one of the high-risk populations for Entamoeba histolytica (E. histolytica) infection. Accompanied by the prevalence of human immunodeficiency virus (HIV) among MSM, invasive amebiasis caused by E. histolytica has been paid attention to as an opportunistic parasitic infection. However, the status(More)
BACKGROUND Anal human papillomavirus (HPV) infection and its related diseases are relatively common in men who have sex with men (MSM), especially in those HIV positive. In China, molecular epidemiology of anal HPV infection among HIV-positive MSM has been sparsely studied. METHODS A cross-sectional study was conducted among HIV-positive MSM in Xi'an,(More)
Anal human papillomavirus (HPV) infection, which is linked to anal warts and anal cancer, is common among men who have sex with men (MSM), especially among those HIV positives. MSM aged 18 years or older were recruited from mainland China. Blood and anal cytologic samples were collected for HIV-1 serological test and HPV genotyping. A total of 889 eligible(More)
