Protective Effects of Angong Niuhuang Pill on Early Atherosclerosis in ApoE-/- Mice by Reducing the Inflammatory Response

Atherosclerosis (AS) is the primary cause of cardiocerebrovascular disease, and inflammation is responsible for the initiation of its pathogenesis. Therefore, targeting inflammatory pathways to prevent AS progression is an ideal strategy. Angong Niuhuang pill (ANP) is a well-known traditional Chinese medicine and has been widely used for thousands of years to treat central nervous system and cardiovascular diseases. In this study, we investigated the role of ANP in reducing inflammation during early AS, using a high-fat diet-induced ApoE−/− mouse model of AS. Compared to those with simvastatin, ANP had no significant effect on serum triglyceride, low-density lipoprotein, and high-density lipoprotein levels. However, it effectively inhibited splenic and vascular inflammation. This agent also reduced the Th17/CD4
