Pingyangmycin-regulated expressions of adhesion molecules in human venous malformation endothelial cells

Pingyangmycin (bleomycin A5 hydrochloride,PYM) is one of the anti-neoplastic agents which have been commonly used to treat venous malformations.However,the underlying mechanism by which PYM treats venous malformations remains poorly understood.It was reported that venous endothelial cells could recruit neutrophils via adhesion molecules (E-selectin,ICAM-1,ICAM-3,VCAM-1) during the acute/chronic inflammation and subsequent histological fibrosis after sclerotherapy with PYM.This study explored if the expression of E-selectin,ICAM-1,ICAM-3 and VCAM-1 in human venous malformation endothelial cells could be affected by PYM.HVMECs were cultured from human venous malformation tissue.Expressions of E-selectin,ICAM-1,ICAM-3 and VCAM-1 on HVMECs in response to PYM were analyzed by cell ELISA.The relative levels of mRNA expression in the cells were semi-quantified.The results showed that PYM up-regulated the expressions of E-selectin,ICAM-3,VCAM-1 and ICAM-1 in both time-and concentration-dependent manner.Our findings suggested that PYM could induce the expression of adhesion molecules in HVMECs,which might be a possible mechanism by which sclerotherapy by intralesional injection of PYM treats venous malformations.

Circulating adhesion molecules in patients with Keshan disease and their relationship with Coxsackie B virus infection

This study determined the levels of serum soluble intercellular adhesion molecule-1 （sI-CAM-l） and soluble vascular cell adhesion molecular-1 （sVCAM-1） in patients with different types of Keshan disease （KD）, examined the relationship between Coxsackie B virus-specific IgM antibody （CBV-IgM） and slCAM-1 or sVCAM-1 in KD patients, and investigated the role of these adhesion molecules in the pathogenesis of KD and their clinical implications. The levels of serum slCAM-1, sVCAM-1 and CBV-IgM were measured by using enzyme-linked immunosorbent assay in 22 patients with chronic Keshan disease （CKD）, 27 with latent Keshan disease （LKD） and 28 healthy controis. The subjects in different groups were adjusted for sex and age. Echocardiography was adopted to determine left ventricular ejection fraction （LVEF） in 22 patients with CKD. The results showed that CKD patients had significantly higher levels of slCAM-1 and sVCAM-1 than LKD patients and healthy controls （P〈0.01 for all）. And there was significant difference in the levels of the 2 adhesion molecules between LKD patients and healthy controls （P〈0.05）. A negative correlation was found between LVEF and slCAM-1 or sVCAM-1 in CKD patients. The percentage of CBV-specific IgM positive individuals in KD patients was significantly higher than that of healthy controls. In CVB-specific IgM positive patients, the levels of serum slCAM-1 and sVCAM-1 were significantly greater than those in CBV-specific IgM negative counterpart. It was concluded that the increase in the levels of slCAM-1 and sVCAM-1 suggests the progression of inflammation in KD. slCAM-1 and sVCAM-1 can promote the development of myocardial pathology and lead to poor myocardial function. The increased serum slCAM-1 and sVCAM-1 in KD patients may be related to CBV infection.

Objective To observe the changes in serum soluble intercellular adhesion molecule type-1(ICAM-1), vascular cell adhesion molecule type-1(VCAM-1), E-selectin and von Willebrand factor (vWf) in patients with acute coronary syndrome. Methods Serial venous blood samples were taken from 21 patients with acute myocardial infarction(AMI) before and 4, 8, 12, 24, 48 and 72 h after thrombolytic treatment or direct PTCA. One blood sample was drawn from 16 patients with unstable angina and 16 control subjects. Serum concentrations of ICAM-1, VCAM-1, E-selectin and vWf were determined using a double antibody sandwich enzyme-linked immunosorbent assay. Results Serum levels of ICAM-1, VCAM-1, E-selectin and vWf were higher in patients with acute coronary syndrome than in controls. Patients with AMI and successful reperfusion therapy had a significant reduction in the serum concentration of ICAM-1 and E-selectin at 24 and 48 h, VCAM-1 at 24 and 72 h and vWf at 12,　24,　48 and 72 h, but had peak in serum levels of ICAM-1 and E-selectin at 4 h. The number of diseased coronary arteries was not related to the levels of ICAM-1,　VCAM-1 and E-selectin. Conclusion The serum concentration of soluble cell adhesion molecules was elevated significantly in patients with acute coronary syndrome. Successful reperfusion therapy was associated with a reduction in the serum concentrations of soluble cell adhesion molecules in patients with AMI.
