Acanthopanax senticosus ameliorates steatohepatitis through HNF4 alpha pathway activation in mice.

Non-alcoholic fatty liver disease is a common liver disease worldwide, and is associated with dysregulation of lipid metabolism, leading to inflammation and fibrosis. Acanthopanax senticosus Harms (ASH) is widely used in traditional medicine as an adaptogen food. We examined the effect of ASH on steatohepatitis using a high-fat diet mouse model. Mice were fed a choline-deficient, L-amino acid-defined, high-fat diet with ASH extract (ASHE). After 6 weeks, liver RNA transcriptome sequencing (RNA-Seq) was performed, followed by Ingenuity Pathway Analysis (IPA). Our findings revealed that mice fed a high-fat diet with 5% ASHE exhibited significantly reduced liver steatosis. These mice also demonstrated alleviated inflammation and reduced fibrosis in the liver. IPA of RNA-Seq indicated that hepatocyte nuclear factor 4 alpha (HNF4 alpha), a transcription factor, was the activated upstream regulator (P-value 0.00155, z score = 2.413) in the liver of ASHE-fed mice. Adenosine triphosphate binding cassette transporter 8 and carboxylesterase 2, downstream targets of HNF4 alpha pathway, were upregulated. Finally, ASHE-treated HepG2 cells exposed to palmitate exhibited significantly decreased lipid droplet contents. Our study provides that ASHE can activate HNF4 alpha pathway and promote fat secretion from hepatocytes, thereby serving as a prophylactic treatment for steatohepatitis in mice.

Effects of audio and visual distraction on patients' vital signs and tolerance during esophagogastroduodenoscopy: a randomized controlled trial.

BACKGROUND: Esophagogastroduodenoscopy (EGD) provides an indispensable and unambiguous inspection allowing the discovery upper gastrointestinal lesions. However, many patients are anxious about undergoing EGD. Few studies have investigated the influence on patients' vital signs and tolerance during EGD using subjective and objective assessments. This study was a prospective randomized controlled study that investigated the influence of audio and visual distraction on EGD. METHODS: We randomly divided 289 subjects who underwent EGD into 4 groups (control group, audio group, visual group, combination group) and examined their vital signs, heart rate variability (HRV), psychological items, and acceptance of distraction. RESULTS: Pulse rate (PR) at post-distraction and post-EGD in the 3 distraction groups were significantly lower than those of control group (p <  0.001 and p <  0.01, respectively). Blood pressure (BP) during and post-EGD was significantly higher than that at pre-EGD in control group (p <  0.05), but no significant elevation of BP was observed during the latter half of EGD and post-EGD in the 3 distraction groups. BP at post-distraction improved significantly compared to pre-distraction in the 3 distraction groups (p <  0.05). There was a significant difference in the low-frequency (LF) power/ high-frequency (HF) power at post-distraction and post-EGD among the 4 groups (p <  0.001 and p <  0.001, respectively). The LF power/HF power at post-distraction and post-EGD in the 3 distraction groups was significantly lower than that in control group (p <  0.05). Several items of profile of mood states (POMS) and the impression of EGD at post-distraction improved significantly compared to those at pre-distraction among the 3 distraction groups (p <  0.05). Visual analog scale (VAS) of willingness for the next use of distraction in the 3 distraction groups was excellent because VAS was more than 70. CONCLUSIONS: Distractions effectively improved psychological factors, vital signs and some of HRV at pre and post-EGD. Distractions may suppress BP elevation during the latter half of EGD and lead to stability of HRV on EGD.
