ABSTRACT
Objective The study was to analyze the relationship between HDL particles,the level of HDL-C and the concordance of HDL-C and apoA-Ⅰand the degree of coronary stenosis,then to explore their values in predicting coronary artery disease.Methods 591 patients were collected for coronary angiography,and calculated Gensini score respectively.HDL particles and the level of HDL-C,apoA-Ⅰwere analyzed in coronary artery disease (CAD)group and non-CAD group,stable angina pectoris(SAP)group and acute coronary syndrome(ACS)group and four groups divided by quartile of Gensini score(A,B,C,D).To investigate the relationship between the con-cordance of HDL-C and apoA-Ⅰand the severity of coronary artery disease,HDL-C,apoA-Ⅰwere divided into low and high group according to the 50 percentile,then pair wise combination was done into four groups. Results Compared with non-CAD group,HDL particles,the level of HDL-C,apoA-Ⅰwere significantly reduced in CAD group(P<0.001).Compared with SAP group,similar results were found in ACS group.HDL particles,the level of HDL-C,apoA-Ⅰwere decreased gradually in A,B,C,D group(P<0.001).The concordance of HDL-C and apoA-Ⅰwas related to the risk of CAD(P<0.001).The area under curve(AUC)of HDL particles was higher than that of HDL-C,the concordance of HDL-C and apoA-Ⅰ.Conclusions HDL particles,HDL-C,the concordance of HDL-C and apoA-Ⅰwere related to coronary stenosis.The value of HDL particles in predicting CAD risk was su-perior to that of HDL-C,the concordance of HDL-C and apoA-Ⅰ.
ABSTRACT
Apolipoprotein A-Ⅰ (ApoA-Ⅰ), the predominant protein in plasma HDL, regulates cholesterol metabolism and exhibits anti-in-flammatory and antioxidant functions. Multiple clinical studies suggest that serum ApoA-Ⅰ levels are associated with the occurrence, development, and prognosis of malignant tumors. Laboratory research also shows that ApoA-Ⅰ and ApoA-Ⅰ mimetics exert antitumor ef-fects through antioxidation, immunoregulation, cholesterol metabolism, lysophosphatidic acid binding, and anti-angiogenesis. This pa-per reviews the role of ApoA-Ⅰ and ApoA-Ⅰ peptides in tumorigenesis and their potential value in diagnosis, treatment, and prognosis.
