Improving the Acceptability of Human Papillomavirus Vaccines Among Men Who Have Sex With Men According to the Associated Factors: A Systematic Review and Meta-analysis.

: To investigate the acceptability of human papillomavirus (HPV) vaccination among men who have sex with men (MSM) and its associated factors. : We searched studies written in English in PubMed, EMBASE, and Web of Science with no geographical or time restrictions. We evaluated the quality of the included literature.

Budd-Chiari Syndrome: The "inferior vena cava reverse-flow" sign and "jet-blood" sign on CT and MRI.

Objective: To investigate the CT and MR features of "inferior vena cava(IVC) reverse-flow" sign and "jet-blood" sign in Budd-Chiari Syndrome (BCS).

Methods: The liver CT and/or MRI plain scan and dynamic enhancement of 107 cases of BCS diagnosed by DSA and/or clinic were collected, including 17 patients with hepatic vein obstruction type, 79 patients with IVC obstruction type, and 11 patients with mixed type. The manifestations of IVC reverse-flow sign and jet-blood sign in the latter two type BCS (90cases) imaging were analyzed.

Alterations of CCR2 and CX3CR1 on Three Monocyte Subsets During HIV-1/ Coinfection.

HIV-1/ () coinfection has become a global challenge, and three monocyte subsets express varying levels of the chemokine receptors CCR2 and CX3CR1. We recently evaluated the association between monocyte subsets and regulatory T cells in HIV-infected individuals with syphilis. Currently, the dynamic changes of CCR2 and CX3CR1 on monocyte subsets during HIV-1 and syphilis coinfection have not been fully investigated.

HIV RNA and proviral HIV DNA can be detected in semen after 6 months of antiretroviral therapy although HIV RNA is undetectable in blood.

The risk of sexual transmission of HIV is strongly correlated with amounts of genital HIV RNA. Few studies have reported amounts of HIV RNA and HIV DNA in semen in HIV-infected Chinese patients undergoing antiviral treatment (ART). In this observational study, the amounts of HIV RNA and HIV DNA in semen were assessed after six months of ART in HIV-infected Chinese individuals, when HIV RNA was undetectable in blood .

CD4+CD25+CD127 regulatory cells play multiple roles in maintaining HIV-1 p24 production in patients on long-term treatment: HIV-1 p24-producing cells and suppression of anti-HIV immunity.

Background: A major question when attempting to eradicate and treat HIV-1 infection is how to reactivate latent proviruses. Stimulating HIV-1-specific cytolytic T lymphocytes (CTL) has been shown to facilitate the elimination of the latent viral reservoir after viral reactivation. Regulatory T (Treg) cells are known to be capable of lowering both HIV-specific immunoreactions and general immune activation during HIV-1 infection.

Regulatory B cells correlate with HIV disease progression.

A rare subset of IL-10-producing B cells, named Breg, was recently identified in mice and humans. Currently, there are no unified cell surface markers to identify Breg, and the relationship between the frequency of Breg and HIV disease progression in chronic HIV infection is unclear. In the present study, we determined whether the cell surface markers of Breg reported for other diseases are suitable for identifying Breg in HIV-infected patients.

[Study on quality of life of asymptomatic HIV infected persons with traditional Chinese medicine].

Objective: Study on quality of life of asymptomatic HIV infected persons with traditional Chinese medical, which can provide the clinical basis for improving the quality of life.

Method: This study applied a randomized, double-blind, and placeb-parallel control designed method to select 1 200 persons in the asymptomatic period of HIV infection as the subjects. The subjects were randomly divided into the treatment group and the control group at the ratio of about 2:1.

Association between X-ray repair cross complementing group 1 codon 399 and 194 polymorphisms and lung cancer risk: a meta-analysis.

Genetic variations in DNA repair genes are thought to modify DNA repair capacity and suggested to be related to cancer risk. However, epidemiological results have been inconsistent. In this meta-analysis, we assessed reported studies of association between polymorphisms of X-ray repair cross complementing group 1 (XRCC1) codon 399 and 194, and lung cancer risk.
