The Correlation between the Inflammatory Effects of Activated Macrophages in Atherosclerosis and Aortic Dissection.

BACKGROUND

To study the correlation between lipid metabolism index, inflammatory factor index, and M1 macrophage content and aortic dissection.

METHODS

Patients with only basic atherosclerotic diseases were selected as the control group, and patients with only basic atherosclerotic diseases and aortic dissection were set as the experiment group. Blood of patients was collected. Chemiluminescent immunoassay was applied to determine the concentration of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B1 (ApoB1). Enzyme-linked immunosorbent assay was applied to measure the concentration of tumor necrosis factor-α (TNF-α), Interleukin 1β (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10). The content of M1 macrophages in blood was measured with the flow cytometry (FCM) method. The correlation between the inflammatory effects of activated macrophages in atherosclerosis and aortic dissection was analyzed by a simple linear regression analysis.

RESULTS

Concentration of TC, TG, LDL-C, and ApoB and the concentration of TNF-α, IL-1β, and IL-6 in the experiment group were markedly higher compared to those in the control group, whereas the concentration of HDL-C and ApoA1 and IL-10 concentration in the experiment group was markedly lower. The content of M1 macrophage in the control group was significantly lower compared to the experiment group. The proportion of M1 macrophages, concentration of TC, TG, LDL, HDL, ApoA1, and ApoB1, and concentration of TNF-α, IL-1β, IL-6, and IL-10 were all significantly correlated to the occurrence of aortic dissection.

CONCLUSIONS

The proportion of M1 macrophages, concentration of TC, TG, LDL, HDL, ApoA1, and ApoB1, and concentration of TNF-α, IL-1β, IL-6, and IL-10 are significantly correlated with the occurrence of aortic dissection.
