The reporting characteristics and methodological quality of Cochrane reviews about health policy research.

The systematic review has increasingly become a popular tool for researching health policy. However, due to the complexity and diversity in the health policy research, it has also encountered more challenges. We set out the Cochrane reviews on health policy research as a representative to provide the first examination of epidemiological and descriptive characteristics as well as the compliance of methodological quality with the AMSTAR.

The study of KBP of road construction workers of highway AIDS prevention project before and after intervention.

Objective: To get scientific basis for further health education through the research of the road construction workers' KBP before and after the interventions of highway AIDS prevention project.

Methods: Multi-stage random sampling method was employeed to select workers of 8 sites from 14 sites along highway to investigate their AIDS knowledge, belief and performance (KBP) before and after highway AIDS prevention project.

Results: Over 90% of the investigated workers had ever heard about AIDS, and the non-skilled workers of lower educational level improved more after intervention.

[Coxsackievirus A group 16 strain].

Coxsackievirus A group 16 strain (CVA16) is one of the predominate causative agent of the hand, foot and mouth disease (HFHD). It is very helpful to improve the hand, foot and mouth disease and other associated diseases control and prevention by understanding its biological characteristics, pathogenic mechanism and clinical manifestations, laboratory diagnoses, epidemiology and molecular epidemiology. In the future, we should continue to emphasize the study, improve the diagnostic method and develop vaccine of CVA16.
