Popis: | Spontaneous basilar artery occlusive disease is a disease characterized by thickening of the intima of the bilateral internal carotid artery and the anterior and middle cerebral arteries, gradually narrowing the arterial diameter, and compensatory dilatation of the perforating artery at the base of the brain. Aspirin (acetylsalicylic acid), as a classic non-steroidal anti-inflammatory drug, has been proven to have antiplatelet, anti-inflammatory, and immune-regulating effects. But how to achieve long-term sustained release of aspirin and achieve anti-platelet aggregation remains to be studied. This study intends to build a microsphere sustained-release system to achieve long-term stable and slow release of aspirin drug, thereby achieving a more ideal anti-platelet aggregation effect. The therapeutic effects of three groups of nanoparticle sustained-release drug regimens on platelet aggregation were compared. The results showed that the platelet inhibition rate and NIHSS scores before treatment were compared between the three groups; compared with the other groups, the PLGA group had higher AA and ADP pathway-induced platelet inhibition rates after treatment and lower plasma Lp-PLA2 and NIHSS scores. This shows that aspirin nanoparticle slow-release drugs can effectively increase platelet inhibition rate and improve the antiplatelet ability of patients with spontaneous basilar artery occlusive disease, which is beneficial to promoting prognosis recovery. |
