摘　　要：目的探究下肢动脉硬化闭塞症(ASO)患者血清miR-150和miR-155水平表达对支架植入术再狭窄(ISR)的预测价值。方法选取2020年3月~2022年6月期间在德阳市人民医院接受支架植入治疗的108例ASO患者,根据其术后一年是否发生ISR,分为发生ISR组(n=42)和未发生ISR组(n=66)。实时荧光定量聚合酶链式反应(qRT-PCR)检测患者血清中miR-150和miR-155的相对表达水平;采用Pearson相关性分析血清miR-150,miR-155水平与低密度脂蛋白-胆固醇(LDL-C)、超敏C反应蛋白(hs-CRP)的相关性;采用多因素Logistic回归分析影响ASO患者发生ISR的因素;采用受试者工作特征(ROC)曲线分析血清miR-150,miR-155水平对ASO患者发生ISR的预测价值。结果与未发生ISR组相比,发生ISR组血清miR-150(0.65±0.16 vs 1.01±0.09)水平显著降低,miR-155(1.68±0.39 vs 1.02±0.11),LDL-C(2.85±0.76 mmol/L vs 2.21±0.62mmol/L),hs-CRP(2.36±0.47 mg/L vs 1.82±0.36mg/L)水平显著升高,差异具有统计学意义(t=4.785~14.957,均P<0.05)。经Pearson相关性分析显示,血清miR-150与LDL-C,hs-CRP水平呈显著负相关(r=-0.465,-0.532,均P<0.05),血清miR-155与LDL-C,hs-CRP水平呈显著正相关(r=0.453,0.481,均P<0.05)。多因素Logistic回归分析显示,血清miR-150是影响ASO患者发生ISR的保护因素,血清miR-155,LDL-C和hs-CRP为影响ASO患者发生ISR的危险因素(均P<0.05)。ROC曲线分析显示,血清miR-150,miR-155及二者联合预测ASO患者发生ISR的AUC(95%CI)分别为0.869(0.791~0.926),0.874(0.796~0.930)及0.976(0.926~0.996),联合检测显著优于二者单独预测(Z=2.679,2.745,均P<0.05)。结论ASO支架植入术后发生ISR的患者血清miR-150水平降低,miR-155水平升高,均是影响ASO患者发生ISR的因素,且二者联合具有较高的预测价值。Objective To explore the predictive value of serum microRNA(miR)-150 and microRNA(miR)-155 expression levels in patients with lower limb arteriosclerosis obliterans(ASO)for in-stent restenosis(ISR)after stent implantation.Methods A total of 108 ASO patients who received stent implantation in Deyang People’s Hospital form March 2020 to June 2022 were gathered.They were grouped into two groups based on whether they had experienced ISR one year after surgery:the ISR group(n=42)and the non-ISR group(n=66).Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)was applied to detect the relative expression levels of miR-150 and miR-155 in serum.Pearson correlation was applied to analyze the correlation between serum miR-150,miR-155 levels and low-density lipoprotein cholesterol(LDL-C)and hypersensitive C-reactive protein(hs-CRP).Multivariate logistic regression was applied to analyze the factors influencing the occurrence of ISR in ASO patients.The receiver operating characteristic(ROC)curve was applied to analyze the predictive value of serum miR-150 and miR-155 levels for ISR in ASO patients.Results Compared with non-ISR group,the serum miR-150(0.65±0.16 vs 1.01±0.09)level in ISR group was greatly reduced,while the levels of miR-155(1.68±0.39 vs 1.02±0.11),LDL-C(2.85±0.76 mmol/L vs 2.21±0.62mmol/L)and hs-CRP(2.36±0.47 mg/L vs 1.82±0.36mg/L)were greatly increased,and the differences were statistically significant(t=4.785~14.957,all P<0.05).According to Pearson correlation analysis,serum miR-150 was greatly negatively correlated with LDL-C and hs-CRP levels(r=-0.465,-0.532,all P<0.05),the serum miR-155 level was greatly positively correlated with LDL-C and hs-CRP levels(r=0.453,0.481,all P<0.05).Multivariate Logistic regression analysis showed that serum miR-150 was a protective factor affecting the occurrence of ISR in ASO patients,while serum miR-155,LDL-C and hs-CRP were risk factors affecting the occurrence of ISR in ASO patients(all P<0.05).ROC curve showed that the AUC(95%CI)of serum miR-
