摘  要:目的 探讨动脉瘤性蛛网膜下腔出血(aSAH)早期(72 h)血清血管生成素(Ang)变化情况及其对患者预后的影响.方法 收集于2013年5月至2014年4月在天津医科大学总医院神经外科住院治疗的符合入组条件的aSAH患者37例,分别在发病后8、24及72 h取血检测血清Ang-1、Ang-2和其特异性受体Tie-2水平,与同期来自天津医科大学总医院健康管理中心的健康志愿者39例(对照组)比较,分析其变化情况,并根据随访6个月后扩展格拉斯哥预后评分(GOSE)将患者分为预后良好组(GOSE>5分)和预后不良组(GOSE≤5),分析SAH早期Angiopoietins和Ang-1/Ang-2变化对患者预后可能的影响.结果 SAH早期患者血清Ang-1、Ang-2、Tie-2表达水平和Ang-1/Ang-2比值均呈现不同程度的增高,与健康对照组比较差异均有统计学意义(均P <0.05),预后良好组血清Ang-1、Ang-2水平均高于预后不良组,其中Ang-1水平比较差异有统计学意义[(52±24) mg/L比(37±17) mg/L、(62±26) mg/L比(45±17) mg/L、(107±27) mg/L比(72±18) mg/L],均P<0.05,多因素Logistic回归分析提示,SAH后≤8和24 h血清Ang-1水平是影响患者预后的独立风险因素之一[校正后OR (95% CI)分别是1.095 (1.015 -1.181)、1.109 (1.016-1.211)](均P<0.05),72 hAng-1水平与患者预后呈显著正相关(r=0.627,P<0.01).结论 Angiopoietins参与SAH早期脑损伤(EBI)的理化过程和血脑屏障(BBB)的修复,SAH早期(72 h)较高水平的血清Ang-1表达水平有益于改善患者预后,将成为判定SAH转归的重要标志物之一.Objective To evaluate the association between serum levels of angiopoietins (Ang) during an early period (within 72 h) and clinical outcomes after aneurysmal subarachnoid haemorrhage (aSAH).Methods This prospective study was conducted at Department of Neurosurgery,Tianjin Medical University General Hospital.Blood samples from 37 aSAH patients were collected at 8 h (or 〈 8 h),24 h,72 h after an onset of SAH.The serum levels of Ang-1,Ang-2 and Tie-2 were measured by enzyme-linked immunosorbent assay (ELISA).They were followed up for 3 months by Glasgow outcome score extended (GOSE).Those with GOSE 〉 5 were counted as a good outcome while those with GOSE ≤ 5 had a poor outcome.Results A total of 37 patients with aSAH and 39 healthy controls (HC) were enrolled.The aSAH patients showed a significant rise of Ang-1 within 8 h as compared with HC.The outcomes were good (n=15) and poor (n=22).Serum Ang-1 at 8 h (or〈8 h),24 h and 72 h in good outcomers showed significantly higher than that in poor outcomers [(52±24) vs (37 ± 17) mg/L,(62 ±26) vs (45 ± 17) mg/L,(107 ±27) vs (72 ± 18) mg/L].The serum level of Ang-1 at 8 h and 24 h was one of independent risk factors for aSAH patients by multiariable Logistic regression analysis [adjected OR (95% CI) 1.095 (1.015-1.181) and 1.109 (1.016-1.211)] (P〈0.05).High serum level of Ang-1 during an early period (within 72 h) was associated with good outcomers (r =0.627,P 〈 0.001).Conclusion The serum levels of angiopoietins are significantly altered in aSAH patients,especially higher in good outcomers.And abnormal levels of angiopoietins may affect early brain injury (EBI) after SAH,structural integrity and recovery of blood-brain barrier (BBB) and long-term outcomes in aSAH patients.
