[摘要] 目的 探讨影响急性脑梗死严重程度的因素及外周血淋巴细胞/单核细胞比值(LMR)与急性脑梗死严重程度的关系。 方法 回顾性分析2017年1~12月南京鼓楼医院神经内科及老年科住院的242例急性脑梗死患者的临床资料,其中男154例,女88例。根据入院时美国国立卫生研究院卒中量表(NIHSS)评分将其分为轻度脑梗死组(NIHSS ≤ 5分,n = 181)和中重度脑梗死组(NIHSS > 5分,n = 61);采用Logistic回归分析评估急性脑梗死严重程度的影响因素及LMR与急性脑梗死严重程度的关系。 结果 两组年龄、性别、房颤、饮酒、空腹血糖、LMR、C反应蛋白比较,差异有统计学意义(P < 0.05);与轻度脑梗死组比较,中重度脑梗死组LMR偏低(4.37±1.87 vs. 3.25±2.20,P < 0.05);多因素Logistic回归分析显示,LMR是脑梗死严重程度的影响因素(OR = 0.8,95%CI:0.650~0.985,P < 0.05)。 结论 入院时LMR水平是反映急性脑梗死患者病情严重程度的指标之一,LMR水平越低预示病情越严重。

[Abstract] Objective To investigate the factors affected the severity of acute ischemic stroke and the relationship between lymphocyte/monocyte ratio (LMR) and acute ischemic stroke severity. Methods From January to December 2017, clinical data of 242 patients with acute ischemic stroke who admitted to the Department of Neurology or Geriatrics, Nanjing Drum Tower Hospital were analyzed retrospectively, including 154 males and 88 females. According to the National Institute of Health Stroke Scale (NIHSS), they were divided into mild cerebral infarction group (NIHSS ≤ 5, n = 181) and moderate-severe cerebral infarction group (NIHSS > 5, n = 61) score at the time of admission. Logistic regression analysis was used to analyze the influence factors of stroke severity. Results There was a statistically significant difference in age, gender, atrial fibrillation, alcohol consumption, fasting glucose, LMR, and CRP between the two groups (P < 0.05). LMR was significantly lower in the moderate-severe cerebral infarction group compared with the mild cerebral infarction group (3.25±2.20 vs. 4.37±1.87, P < 0.05). The multivariate Logistic regression analysis showed that LMR was influence factor of the severity of cerebral infarction patients (OR = 0.8, 95%CI: 0.650-0.985, P < 0.05). Conclusion LMR on admission can reflect the severity of cerebral infarction patients. The lower level of LMR on admission, the more severer condition of the cerebral infarction patients.

腦梗死具有高发病率、高致死率和高致残等特点。据统计,在中国每年大约有240万新发脑梗死,其中每1万人中有159人死亡[1],且其高致残率给社会和家庭带来沉重经济负担。脑梗死发病机制复杂,其中免疫炎性反应在脑梗死发生发展过程中起着重要作用,脑梗死后活化的炎症细胞、炎症介质、血脑屏障的破坏等均可诱发及加重炎性反应,从而引发一系列复杂的病理生理过程[2-3]。淋巴细胞和单核细胞是炎性反应重要的免疫细胞,可以综合反映机体免疫状态。淋巴细胞/单核细胞比值(LMR)是新近发现的一种炎症指标,低水平的LMR与多种肿瘤不良预后有关[4]。研究发现,LMR与ST段抬高型心肌梗死严重程度及预后相关,低水平LMR是急性心肌梗死(STEMI)患者经皮冠状动脉介入(PCI)治疗后院内和长期心血管事件的独立测因子[5-6]。最……
