-
摘要:
目的 分析血清微小RNA-155(microRNA-155,miR-155)、肝素结合蛋白(heparin-binding protein,HBP)与慢性阻塞性肺疾病急性加重(acute exacerbation of chronic obstructive pulmonary disease,AECOPD)治疗效果的关系及预测价值探讨。 方法 选取2023年3月至2024年10月云南省第一人民医院接受治疗的AECOPD患者230例,根据治疗10 d后治疗效果分为无效组(n = 60)、有效组(n = 170),比较两组治疗前一般资料、血清miR-155、HBP水平。分析AECOPD治疗无效的影响因素及血清miR-155、HBP预测治疗无效的价值。 结果 无效组血清miR-155、HBP水平高于有效组(P < 0.05);血清miR-155、HBP单独预测AECOPD治疗无效的曲线下面积(area under the curve,AUC)分别为0.728、0.735;miR-155、HBP联合预测AECOPD治疗无效的AUC为0.868,明显大于miR-155、HBP、急性生理和慢性健康状况评分系统Ⅱ(acute physiology and chronic health evaluation Ⅱ,APACHEⅡ)评分、第1 秒用力呼气肺活量(forced expiratory volume in first second,FEV1)、PCT、hs-CRP单独预测的AUC(P < 0.05)。 结论 治疗前血清miR-155、HBP水平是AECOPD治疗无效的独立影响因素,有助于预测治疗无效风险,血清miR-155、HBP联合能提高预测价值。 Abstract:Objective To analyze the relationship between serum microRNA-155 (miR-155), heparin-binding protein (HBP) and the therapeutic effect of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and its predictive value. Methods Two hundred and thirty patients with AECOPD who received treatment in the First People's Hospital of Yunnan from March 2023 to October 2024 were selected. According to the treatment effect after 10 days of treatment, they were divided into ineffective group (n = 60) and effective group (n = 170). The general data, serum miR-155 and HBP levels before treatment were compared between the two groups. The influencing factors of ineffective treatment of AECOPD and the value of serum miR-155 and HBP in predicting ineffective treatment were analyzed. Results The levels of serum miR-155 and HBP in the ineffective group were higher than those in the effective group (P < 0.05). The area under the curve (AUC) of serum miR-155 and HBP alone in predicting AECOPD treatment failure were 0.728 and 0.735, respectively. The AUC of miR-155 combined with HBP in predicting the ineffective treatment of AECOPD was 0.868, which was significantly higher than that of miR-155, HBP, APACHE II score, FEV1, PCT and hs-CRP alone (P < 0.05). Conclusion The levels of serum miR-155 and HBP before treatment are independent influencing factors of ineffective treatment of AECOPD, which is helpful to predict the risk of ineffective treatment. The combination of serum miR-155 and HBP can improve the predictive value. -
