Cardiovascular diseases have become a mainstream disease by intensifying the country's population aging. The purpose of this article is to explore the specific effect and mechanism of lipid metabolism imbalance through the NF-KB pathway on atherosclerosis and vascular aging in rats. Twenty healthy adult rats were randomly divided into two groups, control in the observation group and the observation group. The rats in the observation group were fed a high-fat diet to imbalance the lipid metabolism of the rats. Immunohistochemistry and transmission electron microscope detectors were used to observe the NF-KB pathway in rats and study atherosclerosis-specific conditions of sclerosis and vascular aging. The results show that the imbalance of lipid metabolism through the NF-KB pathway can increase the rate of apoptosis in rat blood vessels by 24% and the proliferation rate by 18%. The number of vascular endothelial cell damage increased by 33%, which promoted atherosclerosis in rats and increased the rate of vascular aging in rats by 27%.
心血管疾病随着国家人口老龄化的加剧已成为一种主流疾病。本文旨在通过 NF-KB 通路探讨脂质代谢失衡对大鼠动脉粥样硬化和血管老化的具体作用及机制。将 20 只健康成年大鼠随机分为两组,即对照组和观察组,观察组大鼠给予高脂饮食以使大鼠的脂质代谢失衡。采用免疫组化和透射电子显微镜检测大鼠 NF-KB 通路,研究动脉粥样硬化的硬化和血管老化的具体情况。结果表明,通过 NF-KB 通路的脂质代谢失衡可使大鼠血管的凋亡率增加 24%,增殖率增加 18%。血管内皮细胞损伤数量增加 33%,从而促进大鼠动脉粥样硬化,使大鼠血管老化率增加 27%。
