The alterations of degree centrality in the frontal lobe of patients with panic disorder

Objective: The brain network in panic disorder (PD) is still an intriguing issue for research. In this study, we hoped to investigate the role of DC (degree centrality) for the pathophysiology of PD, especially for the fear network.Methods: We enrolled 60 patients with PD and 60 controls in the current study. The gender and age were matched for two groups. All participants received the resting-state functional magnetic resonance imaging to survey the baseline brain activity. Then the DC values of all participants were using REST toolbox. We also compared the DC values between PD and controls. The statistical threshold was set as FDR (false discovery rate) < 0.05.Results: The DC values were significantly lower in the right superior frontal gyrus of PD patients compared to controls (FDR < 0.05). In addition, a negative correlation between the DC values and panic severity was observed in the right superior frontal gyrus and left inferior frontal gyrus. However, there was no significant association between the DC values and illness duration.Conclusion: The DC seemed significantly altered in the frontal lobe of PD patients. The role of the frontal lobe might be more emphasized in the pathophysiology research for PD.     

LncRNA UCA1, miR‐26a,and miR‐195 in coronary heart disease patients: Correlation with stenosis degree,cholesterol levels,inflammatory cytokines,and cell adhesion molecules

BackgroundLong noncoding RNA urothelial cancer‐associated 1 (lnc‐UCA1) targets microRNA‐26a (miR‐26a) and microRNA‐195 (miR‐195) to participate in coronary heart disease (CHD) progression via regulation of vascular smooth muscle cell and microvascular endothelial cell viability and mobility. Therefore, this study set out to further explore the relationship between lnc‐UCA1 and miR‐26a and miR‐195, along with their roles in the management of patients with CHD.MethodsOne hundred and thirty‐six CHD patients and 70 age‐/gender‐matched controls were recruited in this case‐control study. Their peripheral blood mononuclear cell samples were collected for lnc‐UCA1, miR‐26a, and miR‐195 measurement. Furthermore, serum samples from CHD patients were obtained for inflammatory cytokines and cell adhesion molecules measurement. The Gensini score was used to evaluate the stenosis severity in CHD patients.ResultsLnc‐UCA1 expression tend to be increased, while miR‐26a and miR‐195 expressions were reduced in patients with CHD compared to that of controls (all p < 0.001). In CHD patients, lnc‐UCA1 was negatively correlated with miR‐26a (p < 0.001) and miR‐195 (p = 0.014). Besides, lnc‐UCA1 was positively correlated with Gensini score (p < 0.001), total cholesterol (p = 0.019), low‐density lipoprotein cholesterol (p = 0.002), and C‐reactive protein (p < 0.001), while miR‐26a (p < 0.001) and miR‐195 (p = 0.002) were negatively correlated with Gensini score. What''s more, lnc‐UCA1 was positively correlated with tumor necrosis factor (TNF)‐α (p = 0.004), interleukin (IL)‐1β (p = 0.041), vascular cell adhesion molecule‐1 (VCAM‐1) (p = 0.010), and intercellular adhesion molecule‐1 (ICAM‐1) (p < 0.001). While miR‐26a was negatively correlated with some of the individual inflammatory cytokines and cell adhesion molecules.ConclusionLnc‐UCA1, miR‐26a, and miR‐195 may serve as potential biomarkers for CHD management.
