However, no studies have explored the outcome of phased progression of atherosclerosis by non-contrast computed tomography in asymptomatic people in China. The population-based cohort study in outcome of phased progression of atherosclerosis in China （PERSUADE）, an observational, longitudinal and prospective cohort study in a target population of healthy sub- jects based in Jidong Oilfield （China）, prospectively analyzes the outcome of phased progression of atherosclerosis by non-contrast computed tomography in healthy population. The results of this study are expected to be of value for utilizing noninvasive imaging combine with tradi- tional cardiovascular risk factors to create a risk stratification and find pertinent biomarkers associated with the outcome of phased progres- sion of atherosclerosis in healthy people, thereby could help to establish a more personalized treatment of clinical practice.展开更多

Little is known for that in China, except few sporadic studies. To understand prevalence of HHV-6 antibody in Chinese population,this seroepidemiological study was conducted.Methods. Sera were collected from 430 healthy persons and donors living in North China,and tested for HHV-6 antibodies using IFA with HHV-6 GS strain passaged on HSB-2 cells as antigen, and titer e-qual or higher than 1:10 was regarded as seropositive.Results. Of the 430 serum samples tested,297 (69.1%) were positive for HHV-6 IgG. Both seropositive rate and GMT in females were significantly higher than those in males,with X2 = 7. 05,P<0. 01 and F = 7.23,P<0. 01,respectively. Statistically significant difference in prevalence of HHV-6 antibody among various age groups was observed in both sexes,with X2=20. 08 and 20. 28,P = 0. 04,respectively,and young children had a higher titer than adults. But, no significant difference in prevalence was observed in blood donors between various age groups or both sexes.Conclusions. This study suggests that HHV-6 infection with seropositive IgG is ubiquitous in North China,and its importance should be further studied.展开更多
