20 patients with type 2 diabetes mellitus
Fasting blood glucose and TCD will be measured in 20 patients with type 2 diabetes mellitus, and the data of Vm, 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.

20 healthy volunteers whose sex and age and BMI matched with the experimental group
Fasting blood glucose and TCD will be measured in healthy control group, and the data of Vm, 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.
