Metabolic syndrome is associated with increased risk of Barrett esophagus: A meta-analysis.

Background: Barrett esophagus (BE) is considered precursor condition of esophageal adenocarcinoma. Its incidence and prevalence are increasing in general population. Studies reported that metabolic syndrome (MS) or diabetes mellitus (DM) is related to increased risk of BE.

[Association of CCR5, CCR2 and SDF1 gene polymorphisms with HIV-1 infection in Chinese population: a meta-analysis].

Objective: To explore the association of CCR5δ32, CCR2-64I and SDFl-3 A gene polymorphisms with HIV-1-infection in Chinese population.

Methods: A meta-analysis was performed to identify case-control studies of CCR5δ32, CCR2-64I and SDFl-3 A polymorphisms from the literatures.

Results: Fourteen studies of CCR5δ32 were found, involving a total of 1607 cases and 1632 controls.

[Inhibitory effect of resveratrol against enterovirus type 71 in vitro].

Objective: To observe the inhibitory effect of resveratrol against the cytopathogenicity of enterovirus type 71.

Methods: The cytotoxicity of resveratrol on Vero cells was detected using cell counting kit-8 (CCK-8). The antiviral activity of resveratrol in different stages of infection, with ribavirin as the control, was evaluated by determining the virus inhibition rate, medium effective concentration (IC(50)), and selection index (SI).

[Study on serum p53 protein in cops in Guangzhou city].

Objective: Serum p53 protein overexpression was detected in population exposed to traffic exhaust gas to study the relation between traffic exhaust gas and the increased risk in p53 gene mutation.

Methods: Serum p53 protein expression was measured by enzyme-linked immunosorbent assay. Relationship between different types of job and serum p53 protein overexpression were studied by pearson Chi-square tests.

[Psychological health status of students taking part in medical support for military training on the sea].

Objective: To investigate the adaptability and psychological health status of the students from the military medical universities enrolled in the medical support service for military training on the sea, so as to provide more pertinent and specific psychological advice for students in military medical universities.

Methods: The psychological health status of 139 students were assessed by issuing a self-rating symptom scale (SCL-90) before the training and later before the maneuvers commenced, respectively.

Results: Except for obsessive-compulsive and interpersonal sensitivity factors, significant increases were recorded in the scores for other factors immediately before the maneuvers as compared with those recorded before the training (P<0.
