研究目的: |
探索AS微环境中的IFN-γ和ox-LDL协同调控APC-N分化的具体分子机制,揭示APC-N促进AS进展的关键作用,以期为AS的治疗提供药物作用靶点,为AS的预后提供预测指标。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aims to investigate the specific molecular mechanisms through which IFN-γ and ox-LDL synergistically regulate the differentiation of APC-N within the atherosclerotic microenvironment, and to elucidate the critical role of APC-N in promoting the progression of atherosclerosis (AS). The ultimate objectives are to identify potential therapeutic targets for AS intervention and to establish prognostic biomarkers for the disease. |

排除标准: |
1.其他卒中类型:经影像学证实为出血性脑卒中、脑静脉窦血栓形成或非缺血性病因(如肿瘤、感染、外伤)导致的神经功能缺损。 2.既往严重残疾:卒中前mRS评分 ≥ 2分,表明存在严重的既存神经功能残疾。 3.合并严重系统性疾病:合并患有严重的心、肝、肾功能不全(如NYHA心功能分级III-IV级、肝功能Child-Pugh C级、需要透析的终末期肾病)、血液系统疾病、晚期恶性肿瘤或任何预期寿命不足1年的疾病。 4.凝血功能严重障碍:已知的遗传性或获得性凝血功能障碍,且无法通过常规治疗纠正;随机化前血小板计数 < 100×10⁹/L。 5.活动性出血或高风险:近期(3个月内)有重大外伤、消化道出血、颅内出血史;已知的颅内动脉瘤、动静脉畸形或血管炎。 6.取栓手术失败或禁忌:机械取栓手术失败(如血管再通失败,mTICI分级 < 2b级)或存在血管内治疗禁忌症。 7.合并其他干预:本次发病后已接受静脉溶栓以外的再灌注治疗(如动脉溶栓、颅外段颈动脉支架植入术)。 8.取栓标本不合格:术中未能获取符合要求的栓子标本(如无标本、标本碎片化严重、直径均<2mm)。 9.影像学排除:术前影像(CT/MRI)显示大面积低密度/梗死灶(ASPECTS评分 < 6分或后循环梗死体积 > 70ml),或存在明显的占位效应/中线移位。 10.术后出血:取栓术后24小时内影像学复查证实有症状性颅内出血。 11.超窗:发病至股动脉穿刺时间超过规定时间窗(前循环>24小时,后循环>12小时)。 12.无法完成随访:因地理、社会或心理因素,预计无法完成研究规定的临床和影像学随访。 13.妊娠:已怀孕、处于哺乳期或计划在未来6个月内怀孕的育龄期女性(除非血/尿妊娠试验为阴性)。 14.过敏:对研究中使用的造影剂、麻醉药物或后续可能用于分析的药物有明确过敏史。 15.参与其他研究:当前正在参与其他可能干扰本研究结果判定的干预性临床试验。 16.知情同意困难:存在严重认知或精神障碍,或任何其他原因导致无法理解并提供书面知情同意。 |

Exclusion criteria: |
1. Other Stroke Types: Hemorrhagic stroke, cerebral venous sinus thrombosis, or neurological deficits caused by non-ischemic etiologies (e.g., tumor, infection, trauma) confirmed by neuroimaging. 2. Pre-existing Severe Disability: Pre-stroke modified Rankin Scale (mRS) score ≥ 2, indicating significant pre-existing neurological disability. 3. Significant Comorbid Systemic Diseases: Presence of severe cardiac, hepatic, or renal insufficiency (e.g., NYHA Class III-IV heart failure, Child-Pugh Class C liver cirrhosis, end-stage renal disease requiring dialysis), hematological diseases, advanced malignancy, or any other disease with a life expectancy of less than one year. 4. Severe Coagulopathy: Known hereditary or acquired coagulation disorders that cannot be corrected with conventional therapy; Platelet count < 100 × 10⁹/L prior to randomization. 5. Active Bleeding or High Risk of Bleeding: History of major trauma, gastrointestinal bleeding, or intracranial hemorrhage within the past 3 months; Known intracranial aneurysm, arteriovenous malformation, or vasculitis. 6. Failed or Contraindicated Thrombectomy: Failure of mechanical thrombectomy procedure (e.g., failure of revascularization, mTICI grade < 2b) or presence of any contraindication to endovascular therapy. 7. Concomitant Interventions: Having received other reperfusion therapies besides intravenous thrombolysis after the current onset (e.g., intra-arterial thrombolysis, extracranial carotid artery stenting). 8. Non-Qualifying Thrombus Specimen: Failure to retrieve a thrombus specimen meeting the requirements during the procedure (e.g., no specimen, severely fragmented specimens, all fragment diameters < 2 mm). 9. Imaging Exclusions: Pre-procedural imaging (CT/MRI) demonstrates a large infarct core (ASPECTS score < 6 for anterior circulation or infarct volume > 70 mL for posterior circulation) or significant mass effect/midline shift. 10. Post-Procedural Hemorrhage: Symptomatic intracranial hemorrhage confirmed by follow-up imaging within 24 hours post-thrombectomy. 11. Exceeding Time Window: Time from symptom onset to femoral artery puncture exceeds the specified windows (>24 hours for anterior circulation or >12 hours for posterior circulation). 12. Inability to Complete Follow-up: Inability to complete the clinical and imaging follow-ups as required by the study protocol due to geographical, social, or psychological reasons. 13. Pregnancy or Lactation: Pregnancy, lactation, or intention to become pregnant within the next 6 months for women of childbearing potential (unless a negative blood/urine pregnancy test is confirmed). 14. Allergy: Documented history of allergy to contrast agents, anesthetics used in the study, or drugs that may be used in subsequent analyses. 15. Participation in Other Clinical Trials: Concurrent participation in another interventional clinical trial that may interfere with the outcome assessment of this study. 16. Impaired Consent: Presence of severe cognitive or psychiatric impairment, or any other condition that precludes the ability to understand and provide written informed consent. |
