TY - JOUR AB - Expression characteristics of inflammatory factors interleukin‑23 and interleukin‑35; oxidative stress markers of malondialdehyde, which is a final product of lipid peroxidation; superoxide dismutase; microRNA‑126 and microRNA‑146a in serum of patients with coronary heart disease were investigated. Correlation between these biomarkers and CACS (calcification score), as well as the underlying clinical significance were evaluated. A total of 192 patients diagnosed with coronary heart disease were recruited as the observation group, and 69 healthy adults who provided their blood samples were selected as the control group. Enzyme linked immunosorbent assay was carried out to measure the levels of inflammatory factors interleukin‑23 and interleukin‑35, and the levels of oxidative stress markers of malondialdehyde and superoxide dismutase in serum of the patients and healthy subjects. Real‑time fluorescence‑based quantitative PCR was performed to measure the expression levels of microRNA‑126 and microRNA‑146a in serum. The differences in expression of these biomarkers were analyzed, and correlation between these biomarkers and coronary artery calcium score were assessed. The differences in expression levels of interleukin‑23, interleukin‑35, malondialdehyde, superoxide dismutase, microRNA‑126 and microRNA‑146a were statistically significant in both groups. The expression levels of interleukin‑23, interleukin‑35, malondialdehyde, superoxide dismutase, microRNA‑126 and microRNA‑146a in the observation group were closely associated with severity of the disease. There were positive correlations between coronary artery calcium score and interleukin‑23, interleukin‑35, malondialdehyde, microRNA‑126 and microRNA‑146a, respectively; while a negative correlation existed between coronary artery calcium score and superoxide dismutase in the observation group. In conclusion, biomarkers interleukin‑23, interleukin‑35, malondialdehyde, superoxide dismutase, microRNA‑126 and microRNA‑146a were abnormally expressed in serum of patients with coronary heart disease, implicating their association with onset and progression of the disease. The biomarkers were found to be correlated with coronary artery calcium score. Detection of changes of related biomarkers in serum may have certain value in diagnosis of disease formation, as well as assessment of disease severity.
