摘　　要：背景急性脑梗死(ACI)发病率、致残率均较高,威胁患者健康,故早期诊断ACI对于针对性治疗方案的制定及患者预后的改善具有积极意义。微小RNA-145(miR-145)靶向下调程序性细胞死亡因子4(PDCD4)水平可缓解ACI引起的炎性反应,二者可能与ACI的发生有关。目的分析ACI患者血清miR-145、PDCD4 mRNA水平变化及诊断价值。方法选择2019年1月至2020年6月衡水市人民医院神经内科收治的ACI患者185例为ACI组。根据入院时美国国立卫生研究院卒中量表(NIHSS)评分将ACI患者进一步分为轻度损伤亚组(NIHSS评分≤15分,72例)、中度损伤亚组(NIHSS评分为16~29分,64例)、重度损伤亚组(NIHSS评分≥30分,49例)。根据ACI患者脑梗死体积大小,将其进一步分为小体积亚组(脑梗死体积<5 cm^(3),69例)、中等体积亚组(脑梗死体积为5~10 cm^(3),62例)、大体积亚组(脑梗死体积>10 cm^(3),54例)。同期选择在本院体检的健康者150例为对照组。收集所有受试者一般资料,并检测其血清miR-145、PDCD4 mRNA水平。采用Pearson相关分析探讨ACI患者血清miR-145水平与血清PDCD4 mRNA水平间的相关性;采用多因素Logistic回归分析探讨ACI的影响因素;采用受试者工作特征(ROC)曲线分析胱抑素C及血清miR-145、PDCD4 mRNA水平对ACI的诊断价值。结果ACI组有高血压史者所占比例、收缩压、舒张压、低密度脂蛋白胆固醇(LDL-C)、同型半胱氨酸、胱抑素C高于对照组(P<0.05)。ACI组血清miR-145水平低于对照组,血清PDCD4 mRNA水平高于对照组(P<0.05)。中度损伤亚组、重度损伤亚组血清miR-145水平低于轻度损伤亚组,血清PDCD4 mRNA水平高于轻度损伤亚组(P<0.05);重度损伤亚组血清miR-145水平低于中度损伤亚组,血清PDCD4 mRNA水平高于中度损伤亚组(P<0.05)。中等体积亚组、大体积亚组血清miR-145水平低于小体积亚组,血清PDCD4 mRNA水平高于小体积亚组(P<0.05);大体积亚组血清miR-145水平�Background The incidence rate and disability rate of acute cerebral infarction(ACI)are high,threatening the health of patients.Early diagnosis of ACI are of positive significance for the formulation of targeted treatment and the improvement of prognosis.Targeted downregulation of programmed cell death 4(PDCD4)levels by microRNA-145(miR-145)can alleviate the inflammatory response caused by ACI,and the two may be related to the occurrence of ACI.Objective To investigate the changes and diagnostic value of serum miR-145 and PDCD4 mRNA in patients with ACI.Methods A total of 185 ACI patients admitted to the Department of Neurology of Hengshui People's Hospital from January 2019 to June 2020 were selected as ACI group.According to the National Institutes of Health Stroke Scale(NIHSS)score at admission,ACI patients were further divided into mild injury subgroup(NIHSS score≤15,72 cases),moderate injury subgroup(NIHSS score 16~29,64 cases)and severe injury subgroup(NIHSS score≥30,49 cases).According to the size of cerebral infarction,ACI patients were further divided into small volume subgroup(cerebral infarction volume<5 cm^(3),69 cases),medium volume subgroup(cerebral infarction volume 5~10 cm^(3),62 cases)and large volume subgroup(cerebral infarction volume>10 cm^(3),54 cases).In the same period,150 healthy persons who came to our hospital for physical examination were selected as the control group.The general data of all subjects were collected,and the levels of serum miR-145 and PDCD4 mRNA were detected.Pearson correlation analysis was used to explore the correlation between serum miR-145 level and serum PDCD4 mRNA level in patients with ACI;multivariate Logistic regression analysis was used to explore the influencing factors of ACI;the diagnostic value of cystatin C,serum miR-145 and PDCD4 mRNA levels in ACI was analyzed by receiver operating characteristic(ROC)curve.Results The proportion of patients with hypertension history,systolic blood pressure,diastolic blood pressure,low density lipoprotein cholesterol(
