Use of Diterpene Ginkgolides Meglumine Injection to Regulate Plasma Levels of PAI-1 and t-PA in Patients With Acute Atherosclerotic Cerebral Infarction

Background: To: (i) explore the effect of diterpene ginkgolides meglumine injection (DGMI) on neurological deficit symptoms in acute atherosclerotic cerebral infarction (AACI) patients; (ii) measure the level of plasma plasminogen activator inhibitor (PAI)-1 and tissue plasminogen activator (t-PA). Methods: Eighty AACI patients were divided equally and randomly into the DGMI group and control group. In addition to basic treatment, the DGMI group was treated with DGMI (25 mg/d) for 14 days. The control group had basic treatment without DGMI. Before and after treatment, the degree of neurological deficit was assessed, thromboelastography undertaken, and plasma levels of PAI-1 and t-PA measured. Results: The National Institutes of Health Stroke Scale score of patients in the DGMI group after treatment was lower than that in the control group, and the Barthel Index was higher than that in the control group (P<0.05). Thromboelastography revealed that, in the DGMI group, the R value and K value after treatment were higher than before treatment, the angle and maximum amplitude value were lower than before treatment, and both were significant (P<0.05). Compared with the control group, the plasma PAI-1 level of patients in the DGMI group was lower than that in the control group, and the t-PA level was higher than that in the control group (P<0.05) after 14 days of treatment. Conclusions: DGMI may affect the activity of the blood coagulation and fibrinolysis system by regulating the plasma level of PAI-1 and t-PA, and improving neurological deficit symptoms. DGMI is important for improving the prognosis of patients with AACI.
