摘要: 本研究探讨颈动脉超声定量参数联合微小核糖核酸128-3p (miR-128-3p)在急性脑梗死(ACI)诊断及预后预测中的应用价值。选取120例ACI患者作为观察组,选择100例年龄、性别匹配的健康志愿者作为对照组,通过RT-qPCR法检测两组受试者的外周血miR-128-3p水平,对观察组患者进行颈动脉超声检查,同时比较观察组不同神经功能受损患者和不同预后患者的颈动脉超声定量参数和miR-128-3p水平差异。观察组的外周血miR-128-3p相对表达量高于对照组(P<0.05)。重度受损患者的收缩期峰值血流速度(PSV)明显低于轻度和中度受损患者(P<0.05),而舒张末期血流速度(EDV)、颈总动脉内膜-中层厚度(IMT)及miR-128-3p相对表达量明显高于轻度和中度受损患者(P<0.05)。预后不良患者的PSV低于预后良好患者(P<0.05),而EDV、IMT和miR-128-3p相对表达量高于预后良好患者(P<0.05)。颈动脉超声定量参数联合miR-128-3p预测急性脑梗死预后不良的ROC曲线下面积为0.986,高于各指标单独预测(P<0.05)。PSV、EDV、IMT和miR-128-3p相对表达量与患者神经功能受损程度、预后相关,颈动脉超声定量参数联合miR-128-3p在预测患者预后方面有一定应用价值。

Abstract: This study investigated the application value of quantitative parameters of carotid ultrasound combined with microRNA 128-3p (miR-128-3p) in the diagnosis and prognosis prediction of acute cerebral infarction(ACI). 120 patients with ACI were selected as the observation group, and 100 healthy volunteers matched for age and gender were selected as the control group. The levels of miR-128-3p in peripheral blood of the two groups were detected by RT-qPCR, and carotid ultrasound examination was performed in the observation group. At the same time, the quantitative parameters of carotid ultrasound and the level of miR-128-3p difference were compared between patients with different neurological impairment and patients with different prognosis in the observation group. The relative expression of miR-128-3p in peripheral blood of the observation group was higher than that of the control group (P<0.05). The peak systolic velocity (PSV) of patients with severe impairment was significantly lower than that of patients with mild and moderate impairment (P<0.05), while the relative expression levels of end diastolic blood flow velocity (EDV), carotid intima-media thickness (IMT) and miR-128-3p were significantly higher than those of patients with mild and moderate impairment (P<0.05). The PSV of patients with poor prognosis was lower than that of patients with good prognosis (P<0.05), while the relative expression levels of EDV, IMT and miR-128-3p were higher than those of patients with good prognosis (P<0.05). The area under the ROC curve of carotid ultrasound quantitative parameters combined with miR-128-3p for predicting poor prognosis of acute cerebral infarction was 0.986, which was higher than that predicted by each index alone (P<0.05). PSV, EDV, IMT and the relative expression of miR-128-3p were related to the degree of neurological impairment and prognosis of patients. Quantitative parameters of carotid ultrasound combined with miR-128-3p have a certain application value in predicting the prognosis of patients.
