ABSTRACT
Objective:To investigate the correlation between specific expression of serum micro ribonucleic acid (miRNA) and dilated cardiomyopathy (DCM) in children.Methods:Sixteen children diagnosed with DCM in Pediatric Heart Center of Beijing Anzhen Hospital from November 2013 to March 2016 were enrolled in the DCM group.Meanwhile, 12 age- and gender-matched healthy children who underwent medical examinations at the same time in the same hospital were selected as the healthy control group.Their serum was collected and miRNA sequencing was performed.The sample size was expanded at the later stage (the DCM group included 30 cases, and the healthy control group included 16 cases). The real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) verification experiment was conducted on 11 miRNAs with statistically significant sequencing results.Results:Serum miRNA sequencing showed that 172 miRNAs were up-regulated but no miRNAs were down-regulated in the DCM group, compared with the healthy control group (fold change>2, P<0.001). Top 11 significantly up-regulated miRNAs were verified by qRT-PCR, and it was found that 8 of the 11 miRNAs (let-7f, let-7g, miR142-5p, miR143-3p, miR26a, miR27a-3p, miR27b-3p, and miR126-3p) in the DCM group were significantly up-regulated (all P<0.05). In the receiver operating characteristic (ROC) curves of DCM patients, the area under the curves of serum miR142-5p, miR143-3p, miR27b-3p, and miR126-3p were 0.983, 0.992, 0.915 and 0.950, respectively, which were statistically significantly different from those of the healthy control group (all P<0.05). Conclusions:Four serum miRNAs (miR-142-5p, miR-126-3p, miR-143-3p and miR-27b-3p) can distinguish children with DCM from healthy children.Circulating miRNAs are effective in screening DCM children.
ABSTRACT
Objective:To identify the risk factors of anxiety disorders among patients undergoing coronary angiography (CAG) and to determine whether the decision of revascularization affect anxiety level following coronary angiography. Methods:A total of 379 patients undergoing CAG in Fuwai Hospital from Dec. 2012 to Dec. 2013 were invited to participate this study. A data-collecting form, which included questions about demographic features, health history, Type A Behavior Questionnaire (TABQ) and Self Rating Anxiety Scale (SAS), was completed by the participants on the day before and the day after CAG. Result:Among these patients, SAS score of both before and the day after CAG were higher than Chinese normative SAS score. Female patients had a higher SAS score level than male patients (40.57±9.53 vs 38.26±9.61, P Conclusion:The anxiety level decreased after CAG, except those who need coronary revascularization surgery.
