In China, due to the aging population and the increase in obesity, the incidence of diabetes is on the rise. Diabetes is the main independent risk factor for cerebrovascular diseases, especially ischemic stroke. Some studies have proved that non-fasting blood glucose concentration is an independent predictor of ischemic stroke and lacunar infarction. Transcranial Doppler (TCD) can evaluate intracranial blood flow patterns real-time and reliably, and provide information about cerebral hemodynamics, cerebrovascular reactivity and various pathological changes. At present, there are some differences in the study of cerebral blood flow velocity in diabetic patients. The purpose of our study is to determine the changes of cerebral blood flow on an empty stomach and 1 hour after meal in patients with type 2 diabetes. In this study, 20 patients with type 2 diabetes mellitus will be selected as the experimental group. 20 healthy volunteers whose sex and age and BMI matched with the experimental group will be selected as the control group. Fasting blood glucose and TCD will be measured in the two groups, and the data of mean flow velocity (Vm), Gosling's pulsatility index (PI) and cerebrovascular reactivity of cerebral artery will be obtained. One hour after drinking 300ml lukewarm water which has dissolved 75g glucose powder, the blood glucose will be detected again and TCD examination will be performed again. Finally, the data will be collected for statistical analysis.
