CD9 was significantly expressed in the atherosclerotic arteries compared to normal young and old arteries (P less then 0.01). The results suggest that CD9 expression may play an important role in the vascular senescence and pathogenesis of atherosclerosis.Syphilis, human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) share transmission routes. Syphilis infection can increase the risk of acquiring and transmitting HIV in key populations. The aims of this study were to investigate the risk factors and co-infection patterns for HIV, HBV and HCV in patients with syphilis. A retrospective study was conducted of 2,412 patients with syphilis (1,922 (79.68%) with latent syphilis, 336 (13.93%) with secondary syphilis, 78 (3.23%) with primary syphil-is, 72 (2.99%) with tertiary syphilis, and 4 (0.17%) with congenital syphilis). Positive results were odserved in 8.21% (134/1,620) of patients tested for HIV, 5.75% (82/1,427) for HBV, and 1.02% (14/1,374) for HCV, respectively. Multivariate logistic regression analysis found that male sex (adjusted odds ratio (AOR) 26.03; 95% confidence interval (CI) 10.37-65.36), age less then 55 years, especially age group 25-34-years (AOR 8.06; 95% CI 4.16-15.61), diagnosed at the Department of Infectious Disease (AOR 19.16; 95% CI 9.74-37.69), patients from Southern China, which is a geographical area south of the Qinling-Huaihe line (AOR 1.86; 95% CI 1.06-3.26) and having a rapid plasma reagin titre ≥132 (AOR 1.88; 95% CI 1.12-3.15) were independently associated with HIV infection. Risk factors for HBV co-infection in patients with syphilis, including male sex (AOR 1.78; 95% CI 1.12-2.83) and living in Southern China (AOR 4.66; 95% CI, 2.36-9.17)
