Eligibility

Inclusion Criteria:

1. Diagnosis of acute ischemic stroke.

2. Patients that can be treated with study drug within 72 hours of symptoms onset defined by the "last see normal" principle.

3. 4 = NIHSS score = 16 (total score of upper and lower limbs on motor deficits = 2) at the randomization time.

5. Provision of signed informed consent prior to any study-specific procedure.

Exclusion Criteria:

1. Patients who have received intravenous/intra-arterial thrombolysis or mechanical thrombectomy prior to randomization.

2. Secondary stroke caused by tumor, traumatic brain Injury, hematological disease or other diseases with the explicit diagnosis.

3. mRS grade = 2 pre-morbid historical assessment.

4. Other conditions that lead to motor dysfunction (e.g. claudication, severe osteoarthrosis, rheumatoid arthritis, gouty arthritis or other diseases).

5. Known severe impairment of liver function or renal function.

6. Known hypersensitivity to study drugs.

7. Known severe comorbidity with life expectancy < 3 months.

8. Known massive cerebral infarction combined with disturbance of consciousness (1a = 2 in NIHSS), dementia, mental impairment, or unsuitable for participation, in the opinion of the investigator.

9. Pregnancy or breastfeeding.

10. Participation in another clinical study with an investigational product at any time during the 3 months prior to randomization (regardless of when treatment with the investigational product was discontinued).

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in intercellular adhesion molecule 1 level on day 10 (after the treatment) from baseline	Level of intercellular adhesion molecule 1 is associated with the clinical outcome.	Day 10 ± 2
Other	Change in Interleukin 6 level on day 10 (after the treatment) from baseline	Level of Interleukin 6 is associated with the clinical outcome.	Day 10 ± 2
Other	Change in tumor necrosis factor-a level on day 10 (after the treatment) from baseline	Level of tumor necrosis factor-a is associated with the clinical outcome.	Day 10 ± 2
Other	Change in matrix metalloproteinase 9 level on day 10 (after the treatment) from baseline	Level of matrix metalloproteinase 9 is associated with the clinical outcome.	Day 10 ± 2
Primary	Change in National Institute of Health Stroke Scale score on day 10 (after the treatment) from baseline	The aim is to assess the effects of Xueshuantong lyophilized powder versus placebo on reducing the neurological impairment when initiated within 72 hours of symptom onset in patients with acute ischemic stroke.; The National Institute of Health Stroke Scale is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. It is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.	Day 10 ± 2
Secondary	The proportion of patients with National Institute of Health Stroke Scale score 0-1 on day 10 (after the treatment)	The National Institute of Health Stroke Scale is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. It is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0.	Day 10 ± 2
Secondary	Patients-reported outcome of patients measured by Patient-Reported Outcomes Scale for Stroke on day 10 (after the treatment)	Patient-Reported Outcomes Scale for Stroke, a structured questionnaire-scale was developed suitable for Chinese patients. The score ranges from 0 (best) to 144 (worst).	Day 10 ± 2
Secondary	The proportion of patients with modified Rankin Scale grade =1 on day 90	Modified Rankin Scale, a commonly used scale for measuring the degree of dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. 0 - No symptoms.1 - No significant disability. Able to carry out all usual activities, despite some symptoms.2 - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.3 - Moderate disability. Requires some help, but able to walk unassisted.4 - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.5 - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.6 - Dead. The mRS grade between 3 to 6 points are considered to be poor functional outcome.	Day 90 ± 7
Secondary	The proportion of patients with Barthel Index (BI) score greater than or equal to 90 on day 90	Barthel Index is a commonly used scale for measuring the activity of daily living of people. Score of 10-item scale ranges from 0 (worst) to 100 (best).	Day 90 ± 7
Secondary	Quality of life of patients measured by Stroke-specific quality of life scale on day 90	Stroke-Specific Quality of Life Scale is a standardized instrument for evaluating health-related quality of life. The score of 49-item scale with 12 domains range from 49 (worst) to 245 (best).	Day 90 ± 7
Secondary	Incidence of treatment-related adverse events	Number of patients with any adverse events during the study.	Up to Day 90
