Functional handicap Timeframe: on the 90th day after treatment Proportion of patients achieving a Modified Rankin Scale score of 0 to 1 on the 90th day after treatment. The Modified Rankin Score (mRS) is a 6 point disability scale with possible scores ranging from 0-5\. A separate category of 6 is usually added for patients who expire. The higher the score, the more severe the stroke. ### Secondary outcomes 1. Proportion of Neurological Improvement Timeframe: at 24hours and the 7th day after treatment The proportion of subjects with NIHSS score ≤1 or the decrease of 4 points or more from the baseline at 24 hours and the 7th day after treatment. The National Institutes of Health Stroke Scale (NIHSS) is a 11-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on level of consciousness, eye movements, integrity of visual fields, facial movements,arm and leg muscle strength, sensation, coordination, language,speech and neglect. Each impairment is scored on an ordinal scale ranging from 0 to 2, 0 to 3, or 0 to 4\. Item scores are summed to a total score ranging from 0 to 42 (the higher the score, the more severe the stroke). 2. Proportion of Long-term Improvement Timeframe: on the 90th day after treatment Proportion of patients achieving a mRS of 0 to 2 on the 90th day after treatment. 3. Ordinary distribution of mRS scores Timeframe: on the 90th day after treatment Ordinary distribution of mRS scores on the 90th day after treatment. 4. Barthel Index score Timeframe: on the 90th day after treatment Proportion of patients achieving a Barthel Index score ≥95 on the 90th day after treatment. The Barthel Index of Activities of Daily Living (ADLs) measures functional disability by quantifying patient performance in 10 activities of daily life. These activities can be grouped according to self-care (feeding, grooming, bathing, dressing, bowel and bladder care, and toilet use) and mobility (ambulation, transfers, and stair climbing). 5-point increments are used in scoring, with a maximal score of 100 indicating that a patient is fully independent in physical functioning, and a lowest score of 0 representing a totally dependent bed-ridden state.
