Abstract:
Objective To explore the correlation between serum microRNA-29a-3p(miR-29a-3p),throm-bospondin 2(THBS2)and cardiopulmonary function in children with chronic pulmonary heart disease.Meth-ods A total of 136 children with chronic pulmonary heart disease treated in Shijiazhuang Hospital of Tradi-tional Chinese Medicine from July 2019 to September 2023 were selected as the study subjects.Based on their clinical signs,cardiopulmonary function,and symptoms,they were divided into a compensated group(74 ca-ses)and a decompensated group(62 cases).Real-time fluorescence quantitative PCR(RT-qPCR)method was applied to detect serum miR-29a-3p level,and enzyme-linked immunosorbent assay(ELISA)was applied to detect serum THBS2 level.Moreover,ultrasound diagnostic equipment was applied to detect cardiac function indicators such as left ventricular ejection fraction(LVEF)and cardiac output(CO).Creatine kinase isoenzyme(CK-MB)and troponin(cTnl)were detected by electroluminescence analysis.Pulmonary function indicators were detected by pulmonary artery systolic pressure(PASP),mean pulmonary artery pressure(MPAP)and pulmonary artery diastolic pressure(PADP).Pearson correlation was used to analyze the corre-lation between serum miR-29a-3p and THBS2 levels and cardiopulmonary function indexes in children with chronic pulmonary heart disease,and multivariate Logistic regression analysis was used to screen the influen-cing factors of the disease in children with chronic pulmonary heart disease.Receiver operating characteristic(ROC)curve was drawn to analyze the evaluation value of serum miR-29a-3p and THBS2 levels in children with chronic pulmonary heart disease.Results The THBS2,CK-MB,cTnI,PASP,MPAP,and PADP in the decompensated group were higher than those in the compensated group(P＜0.05),while miR-29a-3p,LVEF,and CO were lower than those in the compensated group(P＜0.05).Serum miR-29a-3p in children with chro-nic pulmonary heart disease was positively correlated with LVEF and CO(P＜0.05),but negatively correla-ted with CK-MB,cTnI,PASP,MPAP,and PADP(P＜0.05).THBS2 was negatively correlated with LVEF and CO(P＜0.05),but positively correlated with CK-MB,cTnI,PASP,MPAP,and PADP(P＜0.05).MiR-29a-3p was a protective factor for exacerbation of chronic pulmonary heart disease in children(P＜0.05),while THBS2 was an independent risk factor for exacerbation of chronic pulmonary heart disease in children(P＜0.05).ROC curve analysis results showed that the area under the curve(AUC)of serum miR-29a-3p and THBS2 levels alone and in combination for evaluating the severity of chronic pulmonary heart disease in children were 0.827,0.817 and 0.915,respectively.Conclusion Serum miR-29a-3p and THBS2 levels are both factors affecting the disease of children with chronic pulmonary heart disease,and are closely related to the disease and cardiopulmonary function of children with chronic pulmonary heart disease.
