Objective To explore the correlation between the recurrence rate of the elderly patients with lacunar infarction and the risk factors including blood pressure, blood glucose, total cholesterol, triglycerides,low density lipoprotein cholesterol values, high-density lipoprotein cholesterol and other. Methods 207 over 60 years old patients with lacunar infarction occurred the first time were included in the study. All patients were followed up two years to assess the relapse rate and the risk factors of the patients with lacunar infarction. Results 207 cases of elderly patients with lacunar infarction complicated with hypertension,type 2 diabetes and hyperlipidemia were 148 cases,22 cases,7 cases respectively, and the recurrence rates of three groups were 8.78%, 18.18%, 14.29% respectively;The patients complicated with hypertension and 2 type diabetes were 6 cases,and the recurrence rate was 34.62%;The patients without hypertension,type 2 diabetes and hyperlipidemia were 4 cases,and the recurrence rate was 0%. In two years,27 cases of lacunar infarction recurred,and the recurrence rate was 13.04%. Conclusion Hypertension,type 2 diabetes,hyperlipidemia could also be considered as the high-risk predictor factors for the recurrence rate of the elderly patients with lacunar infarction.

The negative effects of low temperature can readily induce a variety of diseases. We sought to understand the reasons why cold stress induces disease by studying the mechanisms of fine-tuning in macrophages following cold exposure. We found that cold stress triggers increased macrophage activation accompanied by metabolic reprogramming of aerobic glycolysis. The discovery, by genome-wide RNA sequencing, of defective mitochondria in mice macrophages following cold exposure indicated that mitochondrial defects may contribute to this process. In addition, changes in metabolism drive the differentiation of macrophages by affecting histone modifications. Finally, we showed that histone acetylation and lactylation are modulators of macrophage differentiation following cold exposure. Collectively, metabolism-related epigenetic modifications are essential for the differentiation of macrophages in cold-stressed mice, and the regulation of metabolism may be crucial for alleviating the harm induced by cold stress.
