The results show that the activation of NF-κB in astrocytes is a key factor in the process of cerebral edema after TBI of rats.

Objective: To verify the efficacy and safety of dual antiplatelet therapy after intravenous thrombolysis for acute minor ischemic stroke (AMIS). Methods: AMIS patients who received recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis from January to October 2018 were retrospectively analyzed and divided into the aspirin (ASP) and ASP + clopidogrel (ASP-CLO) groups based on the type of antiplatelet therapy to compare the rates of good clinical outcome, symptomatic intracranial hemorrhage (SICH) after thrombolysis, and mortality in 90 days. Results: A total of 207 patients were included (group ASP, 105 patients; group ASP-CLO, 102 patients). There was no significant difference in the baseline clinical data between the 2 groups. The ­90-day modified Rankin scale scores (66.7 vs. 82.4%, p = 0.009) showed a statistically significant difference, but SICH (1.0 vs. 1.0%, p = 0.917) and 90-day mortality (1.9 vs. 1.0%, p = 0.585) showed no significant difference between the 2 groups. Conclusions: Short-term (21 days) dual antiplatelet therapy after rt-PA intravenous thrombolysis for AMIS can improve the prognosis, reduce the risk of stroke recurrence, without increasing the risk of bleeding and mortality.

Objective:This study aims to observe the clinical efficacies of hyper-early low-dose alteplase thrombolysis in treating acute ischemic stroke (AIS).Methods:Two hundred twenty AIS patients were randomly divided into group A (90 cases), group B (90 cases), and group C (40 cases). The National Institutes of Health Stroke Scale (NIHSS) scores, mRS score-evaluated prognosis, intracranial hemorrhage, and mortality of the three groups were observed before and after the treatment.Results:The NIHSS scores of the three groups were significantly reduced after the treatment (P<0.05), among which the NIHSS score of group A was the lowest (P<0.05); and the difference between group B and C was not significant (P>0.05). The incidence of such complications as cerebral hemorrhage in the three groups was low, and there was no significant difference among the groups (P>0.05). The modified Rankin Scale (mRS)scores of the three groups showed that group A had much better prognosis than group B and C, while the difference between group B and group C was not significant.Conclusions:The hyper-early low-dose alteplase thrombolysis was safe and effective in Acute ischemic stroke (AIS).
