Different effects of mechanical embolus removal and intra-arterial thrombolysis on neural functional recovery in patients with acute middle cerebral artery occlusion

摘要

Objective: To study the different effects of mechanical embolus removal and intra-arterial thrombolysis on neural functional recovery in patients with acute middle cerebral artery occlusion. Methods: Patients with acute middle cerebral artery occlusion who were treated in the First Hospital of Yulin between September 2013 and October 2017 were selected and retrospectively studied, and the differences in reperfusion therapies in history data were referred to divide them into study group A and study group B who underwent mechanical embolus removal and intra-arterial thrombolysis respectively. The levels of neurocyte damage markers, apoptosis markers and stress markers in serum as well as the expression of Wnt pathway molecules in peripheral blood were determined before treatment and 24 h after treatment. Results: Compared with those of same group before treatment, serum NSE, S100B, VILIP1, sFas, sFasL, ET-1 and MDA levels as well as peripheral blood GSK3β, LC3-II and Beclin1 expression intensity of both groups were decreasing whereas serum BDNF, NTF, sLivin and SOD levels as well as peripheral blood β-catenin and mTOR expression intensity were increasing, and serum NSE, S100B, VILIP1, sFas, sFasL, ET-1 and MDA levels as well as peripheral blood GSK3β, LC3-II and Beclin1 expression intensity of study group A after treatment were lower than those of study group B whereas serum BDNF, NTF, sLivin and SOD levels as well as peripheral blood β-catenin and mTOR expression intensity were higher than those of study group B. Conclusion: Mechanical embolus removal for acute middle cerebral artery occlusion can be more effective than intra-arterial thrombolysis to reduce the nerve function damage as well as the corresponding oxidative stress and apoptosis.
