The invention discloses applications of sodium ferulate and expression of CXCL1 genes controlled by sodium ferulate in a mechanism for preventing and controlling atherosclerosis, and relates to a protective effect of sodium ferulate on a human umbilical vein endothelial cell (HUVEC) strain damaged by oxidized low-density lipoprotein (Ox-LDL), and discusses an action mechanism. Human umbilical vein endothelial cells are used to carry out experiments, influences of sodium ferulate on proliferation, migration and apoptosis of HUVEC treated by the oxidized low-density lipoprotein are determined by MTT, scratch test, flow cytometry and confocal microscopy; total RNA of the cells are extracted; marked hybrid experiments are carried out by using a CapitalBio whole-genome chip; differential genes are screened out by analyzing differential expression genes through clustering analysis, GO function and enrichment degree and pathway association degree, so that a gene expression spectrum can be obtained; and transcription and translation of the expressed differential genes in the HUVEC are detected by adopting a real-time quantitative PCR method. The results demonstrate that sodium ferulate can regulate CXCL1 gene expression downwards and has an obvious protective effect on the HUVEC damaged by Ox-LDL.
