摘要:
目的 探究早期他汀类药物治疗对大动脉闭塞性脑卒中(AIS-LVO)对侧支循环、责任血管改善及血栓素B2(TXB2)/前列腺素F1α(PGF1α)的影响。 方法 选取2021年5月至2023年5月太原钢铁(集团)有限公司总医院神经内科收治的105例早期(入院后3 d内)使用他汀类药物治疗的AIS-LVO患者为他汀组,另选取同期105例早期未使用他汀类药物的AIS-LVO患者为非他汀组,比较两组症状评分[美国国立卫生院神经功能缺损评分(NIHSS)、Rankin修订量表(mRS)评分、吞咽功能标准吞咽功能评定量表(SSA)、功能性经口摄食评价量表(FOIS)评分]、责任血管改善情况、TXB2/PGF1α水平、内皮功能指标[碱性成纤维细胞生长因子(bFGF)、外周血循环内皮细胞(CECs)]水平。 结果 他汀组治疗1、2周后NIHSS、mRS、SSA评分水平均低于非他汀组,FOIS评分高于非他汀组(P < 0.02);他汀组责任血管Vm增快、侧支循环代偿改善比例均高于非他汀组(P < 0.05),他汀组CTA侧支循环分级优于非他汀组(P < 0.05);他汀组治疗1、2周后TXB2、TXB2/PGF1α水平均低于非他汀组,PGF1α水平高于非他汀组(P < 0.02);他汀组治疗1、2周后bFGF水平均低于非他汀组,CECs水平高于非他汀组(P < 0.02);他汀组治疗3个月mRS评分0~2分比例高于非他汀组(P < 0.05)。 结论 AIS-LVO患者经早期他汀类药物治疗可改善责任血管血流与内皮功能,调节TXB2/PGF1α水平,促进侧支循环代偿、吞咽功能及神经功能恢复。 Abstract:Objective To investigate the effects of early statin therapy on collateral circulation, responsible vessel improvement, and thromboxane B2 (TXB2)/prostaglandin F1 (PGF1α) in acute ischemic stroke with large vessel occlusion (AIS-LVO). Methods From May 2021 to May 2023, 105 AIS-LVO patients treated with statins within 3 days of admission were selected as the statin group from the Neurology Department of Taiyuan Iron and Steel (Group) General Hospital. Concurrently, 105 early AIS-LVO patients not treated with statins were selected as the non-statin group. The study compared symptom scores [National Institutes of Health Stroke Scale (NIHSS), modified Rankin Scale (mRS), Swallowing Standard Assessment (SSA), and Functional Oral Intake Scale (FOIS) scores], responsible vessel improvement, TXB2/PGF1α levels, and endothelial function indicators [basic fibroblast growth factor (bFGF) and circulating endothelial cells (CECs)]. Results After 1 and 2 weeks , the statin group showed lower NIHSS, mRS, and SSA scores, and higher FOIS scores compared to the non-statin group (P < 0.02). The statin group demonstrated higher rates of responsible vessel velocity increase, collateral circulation compensation, and superior CTA collateral circulation grading (P < 0.05). At 1 and 2 weeks, the statin group had lower TXB2 and TXB2/PGF1α levels, and higher PGF1α levels compared to the non-statin group (P < 0.02). The statin group showed lower bFGF levels and higher CECs levels (P < 0.02). After 3 months, the statin group had a higher proportion of mRS scores of 0~2 (P < 0.05). Conclusion Early statin therapy in AIS-LVO patients can improve responsible vessel blood flow and endothelial function, regulate TXB2/PGF1α levels, promote collateral circulation compensation, and enhance swallowing and neurological function recovery. -
