【摘要】 目的: 分析血清淀粉样蛋白 A(SAA)、 β2- 微球蛋白( β2-MG)水平与急性脑梗死(ACI)患者预后的相关性。方法: 选取 2018 年 2 月至 2020 年 8 月该院收治的 95 例 ACI 患者为研究对象,另选取同期 35 例健康体检者为对照。于入院 1、7、 14 d 后或体检时均采集空腹静脉血检测血清 SAA、 β2-MG 水平,并以美国国立卫生研究院卒中量表(NIHSS)评估 ACI 患者神经功能缺损情 况,入院 90 d 后以改良 Rankin 量表(mRS)评分为标准将 ACI 患者分为预后不良组、预后良好组, 分析 SAA、 β2-MG 水平与 ACI 患者 预后的相关性。 结果: 入院 1、7、 14 d 后, ACI 患者 NIHSS 评分逐渐降低,血清 SAA、 β2-MG 水平随入院时间延长而逐渐降低,但均高 于健康体检者,差异有统计学意义(P<0.05) ;入院 90 d 后, 95 例 ACI 患者中, 62 例预后良好, 33 例预后不良;预后良好组血清 SAA、 β2-MG 水平均低于预后不良组, 差异有统计学意义(P<0.05); 经 Pearson 相关性分析显示, 血清 SAA、 β2-MG 水平与 ACI 患者预后呈负相关(r<0, P<0.05) ;多因素 Logistic 回归分析结果显示,血清 SAA、 β2-MG 水平升高是 ACI 患者预后不良的独立危险因素(OR>1, P<0.05)。 结论: 血清 SAA、 β2-MG 水平与 ACI 患者的预后呈负相关,其水平较高提示患者神经功能缺损较严重、预后较差。

急性脑梗死(Acute cerebral infarction,ACI)发病率较高,预后较差,其病理机制仍不明确,通过科学的治疗可缓解神经功能损伤、挽救患者的生命,但部分患者仍病情改善不佳,预后较差。通过分析ACI患者预后的影响因素能为临床制订干预措施提供依据,达到改善患者预后的目的。血清淀粉样蛋白A(Serum amyloid A,SAA)属载脂蛋白,机体受炎症刺激后血清水平快速提高,且灵敏度较C反应蛋白更高[1]。β2-微球蛋白(β2-microglobulin,β2-MG)与动脉粥样硬化关系密切。本文分析血清SAA、β2-MG水平与ACI患者预后的相关性。Correlation analysis of serum amyloid A, β2-microglobulin levels and prognosis of patients with acute cerebral infarction

【 Abstract 】 Objective: To analyze correlations among serum amyloid A (SAA) and β2-microglobulin (β2-MG) levels and prognosis of patients with acute cerebral infarction (ACI) Methods: 95 ACI patients in this hospital from February 2018 to August 2020 were selected as the research subjects, and 35 healthy physical examination people during the same period were selected as controls. The fasting venous blood was collected 1, 7, 14 d after admission or during the physical examination to detect the serum SAA and β2-MG levels. The National Institute of Health stroke scale (NIHSS) was used to assess the neurological deficits in the ACI patients. 90 days after admission, these ACI patients were divided into poor prognosis group and good prognosis group based on the modified Rankin scale (mRS) score. The correlations among the SAA and β2-MG levels and the prognosis of these ACI patients were analyzed. Results: 1, 7, and 14 d after admission, the NIHSS scores of the ACI patients gradually decreased, and the serum SAA and β2-MG levels gradually decreased with the prolonged admission time; these levels were higher than those of the healthy physical examination people, and the differences were statistically significant (P<0.05). 90 days after admission, among the 95 ACI patients, 62 had good prognosis and 33 had poor prognosis. The serum SAA and β2-MG levels in the good prognosis group were lower than those in the poor prognosis group, and the differences were statistically significant (P<0.05). Pearson correlation analysis showed that the serum SAA and β2-MG levels were negatively correlated with the prognosis of the ACI patients (r<0, P<0.05). Logistic multiple regression analysis showed that the high levels of serum SAA and β2-MG were the independent risk factors of poor prognosis of the patients with ACI (OR>1, P<0.05). Conclusions: The serum SAA and β2-MG levels are negatively correlated with the prognosis of the ACI patients, and their higher levels indicate more severe neurological deficits and poor prognosis
