Arm && Interventions

Group	Intervention	Description
RIC group	Automatic ischemic conditioning treatment instrument	Device: Remote ischemic conditioning RIC is a non-invasive therapy that performed by an electric autocontrol device with cuff placed on arm. RIC procedures consist of five cycles of 5-min inflation (200 mmHg) and 5-min deflation of cuff on one arm. The procedure will be performed twice daily for consecutive 1 year after enrollment.
Regular treatment	Regular treatment	-

Primary Outcome Measures

Name	Time	Method
Changes of volume of WMHs	From baseline to 1 year treatment	The volume of WMHs was measured on Flairs and DTI. By calculating the mean diffusivity (MD) and FA of water diffusion, DTI can assess the integrity and connectivity of WM tissue from a network perspective, and reconstruct the distribution of WM pathways in the brain three-dimensionally.

Secondary Outcome Measures

Name	Time	Method
Changes in hemodynamic parameters on TCD.	From baseline to 1 year treatment	The peak systolic, mean, and end diastolic blood flow velocities (BFV) at the most proximal segment of bilateral MCAs, BA were measured by TCD
Changes of cognition evaluation on MoCA.	From baseline to 1 year treatment	The Beijing version of MoCA were used to evaluate to evaluate the cognitive functions of patients, referring to the degree of an individual's capacity with respect to orientation, memory, calculation, language, execution and visuospatial function and so on
