- Maximum Age: 80 Years
- Healthy Volunteers: f

Study Arms:
- experimental group (Type: EXPERIMENTAL): Recombinant human tissue plasminogen kinase derivatives(r-PA) for injection: the first intravenous bolus injection of 18mg, after 30mins, the second intravenous bolus injection of 18 mg, Push slowly for more than 2mins each time. Subjects were closely monitored during the treatment period and within 24 hours after administration.
- comparative group (Type: ACTIVE_COMPARATOR): Recombinant human tissue plasminogen activator (rt-PA) for injection: 0.9 mg/kg (maximum dose of 90 mg) intravenous, 10% of which was injected intravenously within the first 1min, and the rest continued intravenous infusion for 1 h. Subjects should be closely monitored during the treatment period and within 24 hours after administration.

Based on this trial design, predict the completion outcome and termination type (if applicable).
