[EX Q]: Activation of the transcription factor NF-B and expression of pro-inflammatory mediators have been considered as major events of acute pancreatitis (AP). Karyopherin alpha 2 (KPNA2), a member of the importin family, reportedly modulates p65 subcellular localization.', 'This study aimed to investigate the expression and possible functions of KPNA2 in the AP cell and animal model, focusing on its association with NF-B activation.', 'An AP cell model was established with the cerulein-stimulated AR42J and isolated rat pancreatic acinar cells. The AP rat model was induced by the intraperitoneal injection of cerulein. The secretion of TNF-, IL-6, and LDH was detected by ELISA kits and the production of NO using nitric oxide kit. Expression of KPNA2 was measured by RT-PCR and Western blot. Expression levels of IKK, phosphorylation of p65, and total p65 were detected by Western blot. Co-localization of KPNA2 with p65 was observed by immunofluorescence assay. To determine the biological functions of KPNA2 in cerulein-induced inflammatory response, RNA interference was employed to knockdown KPNA2 expression in AR42J and isolated pancreatic acini cells.', 'Cerulein stimulated KPNA2 expression and IL-6, TNF-, NO, and LDH production in rat pancreatic acinar cells. Cerulein triggered the phosphorylation and nuclear translocation of NF-B p65 subunit, indicating the NF-B activation. The co-localization and nuclear accumulation of KPNA2 and p65 were detected in cerulein-treated cells. Knocking down KPNA2 hindered cerulein-induced nuclear transportation of p65 and alleviated the subsequent inflammatory response in rat pancreatic acinar cells. Additionally, KPNA2 expression was significantly up-regulated in cerulein-induced AP rat model.

[EX Q]: Two-dimensional speckle tracking echocardiography (2DSTE) has been used widely in research, but rarely in clinical practice because data acquisition and analysis are time-consuming. By reducing the acquisition and analysis time, 3-dimensional STE may improve clinical impact. We investigated the feasibility of 3DSTE myocardial deformation, with comparison to 2DSTE.', 'Transthoracic 3DSTE and 2DSTE were performed in 230 adults (138 men, 51 14 years, and 142 hypertension, 10 heart failure and 78 normotensive subjects). The variables of LV deformation were analyzed using EchoPAC software.', 'The 3D LV longitudinal (LS) analysis was feasible in 84.9% of the study subjects, which was lower than the 2D analysis (97.2%). The success rates for circumferential strain (CS) and radial strain (RS) were similar between the 2D and 3D techniques. All magnitude of strains measured by 2DSTE and 3DSTE were significantly correlated. The magnitude of 3D LS and CS was lower, but the 3D RS is higher than that of 2DSTE (-18.5 2.8 vs. -21.2 3.5; 20.8 4.1 vs. 21.7; and 50.0 11.2 vs. 37.7 12.6, respectively). Strains measured by 3DSTE exhibited stronger correlation with LV ejection fraction (EF) than that by 2DSTE. In inter- and intra-observer reproducibility for 3D LS, CS, RS and AS were acceptable. The mean time of analysis for LV volume, EF and strains was 116s by 3DSTE, which was significantly shorter than that by 2DSTE (5 min, P<0.0001).

[EX Q]: Depressed mood has been prospectively associated with hypertension. Altered ANS function, as reflected in poor CV recovery, may be one mechanism that underlies this relationship.', 'The purpose of this study was to investigate the relationship between depressed mood and cardiovascular recovery following a standard mental stress task in healthy young women.', 'Depressed mood was assessed in 63 young women. Cardiovascular data were collected during a 5-min baseline period, 5-min public speaking stress task, and 15-min recovery period.', 'Depressed mood accounted for 9.6% of the variation in HR reactivity (F(1,58) = 6.513, p = 0.013) and 4.5% of DBP recovery (F(1,58) = 4.538, p = 0.037).
