MicroRNAs (miRNAs) are a class of small, non-coding RNAs that regulate gene expression at the post-transcriptional level. Recently, it was reported that miR-137, miR-124, and miR-184 were widely expressed in the central nervous system and were vital to neuronal regulation. In this study, we detected the circulating levels of miR-137, miR-124, and miR-184 in PD patients, and explored the potential role of miR-124, miR-137, and miR-184 in the diagnosis of PD. We further described the relationship between these miRNAs and PD with depression (PD-Dep). The study recruited 60 controls and 60 PD patients, which were further divided into two subgroups, PD with depression (PD-Dep, n = 24) and non-depressed group (PD-NDep, n = 36) according to Hamilton Rating Scale for Depression. Plasma levels of miR-137, miR-124, and miR-184 were detected by qRT-PCR. Receiver-operating characteristic (ROC) curve was used to evaluate miR-124 and miR-137 levels as potential diagnostic biomarkers for PD. The results demonstrated that there were no significant differences in levels of miR-184 between PD patients and controls (p > 0.05). However, miR-137 levels were increased significantly for PD patients compared to controls (p < 0.05), while miR-124 levels were down-regulated (p < 0.05). The areas under the ROC curve (AUC) of miR-137 and miR-124 were 0.707 (95% CI 0.615-0.789, p < 0.05) and 0.709 (95% CI 0.618-0.633, p < 0.05), respectively. Correlation analysis revealed that there was no relationship between these two miRNAs levels and UPDRS scores or H&Y stage. There were no significant differences in miR-137 and miR-124 levels between PD-Dep and PD-NDep (p > 0.05). Thus, plasma levels of miR-137 and miR-124 are associated with Parkinson's disease and might be potential biomarkers of the diagnosis of PD. There were no associations of plasma miR-137 and miR-124 with the severity of PD motor symptoms or PD-Dep.

TAAD with arch entry tear was treated safely and durably by FET + TAR. Although patients with arch entry tear were somewhat older than other patients, operative mortality was not substantially higher despite their older age and arch location of entry tear. These results argue favorably for the use of the FET + TAR technique in the management of TAAD patients with arch entry tears.
