Apolipoprotein E (APOE) is recognized for its importance in lipoprotein metabolism and cardiovascular disease. We evaluated the association between APOE rs4420638 genotypes and circulating lipid concentrations along with the risk of coronary heart disease (CHD). We conducted a case-control study involving 1508 individuals to investigate the contribution of rs4420638 to the risk of CHD in Han Chinese. In addition, we performed a meta-analysis to evaluate the association between rs4420638 and CHD in Europeans and Asians.
This study explored the effect of focal cerebral contusion on the expression of ApoE and S-100, and its significance in determining the time of brain injury. Based on a rat model of cerebral contusion, immunohistochemistry was used to analyze the expressions of S-100 and ApoE at different time points after injury. Thirty minutes following cerebral contusion, ApoE protein expression was significantly increased in cortex neurons (P
