Objective To explore the relationship between biomarkers of infammation and angiotensin Ⅱ(AngⅡ) and plasma renin activity(PRA) among Mongolians.Methods The data on demographics etc.were collected,blood pressures were measured and C-reactive protein(CRP),soluble E-selectin(sE-selectin),soluble intercellular adhesion molecule 1(sICAM-1),AngⅡ and PRA were examined for 2 589 Mongolian.Logistic regression was used to analyze the association between the biomarkers and abnormal AngⅡ and PRA among Mongolian.Results The average levels of sE-selectin was signifcantly higher in the participants with abnormal PRA than those with normal PRA(18.9 vs 17.5 ng/ml,P0.001).Compared with the lowest quartile of sE-selectin,the multivariable-adjusted odds ratio(95% confident interval) of abnormal PRA for the highest quartile was 1.42(1.08~1.87).The average levels of both CRP(6.3 vs 5.5 mg/L) and sICAM-1(335.3 vs 314.4 ng/ml) were signifcantly higher in the participants with abnormal AngⅡ than those with normal AngⅡ.Compared with the lowest quartile of CRP,the multivariable-adjusted odds ratio(95% confident interval) of abnormal Ang Ⅱ for the highest quartile was 1.94(1.44~2.60);compared with the lowest quartile of sICAM-1,the multivariable-adjusted odds ratio(95% confident interval) of abnormal AngⅡ for the highest quartile was 1.44(1.11~1.87).Conclusion The levels of sE-selectin is associated with abnormal PRA,and the levels of CRP and sICAM-1 are associated with abnormal AngⅡ.
