Que Zui tea ameliorates hepatic lipid accumulation and oxidative stress in high fat diet induced nonalcoholic fatty liver disease.

In this study, the protective effects of hot water (QW) and aqueous-ethanol extracts (QA) from Que Zui tea on non-alcoholic fatty liver disease (NAFLD) were investigated. Quantitative and qualitative analysis revealed that QW and QA were rich in polyphenols, especially 6'-O-caffeoylarbutin. Both QW and QA significantly reduced body weight and liver index, increased serum levels of high density lipoprotein cholesterol (HDL-C), and decreased the levels of total cholesterol (TC), triglyceride (TG), nonesterified free fatty acids (NEFA) and low density lipoprotein cholesterol (LDL-C) in NAFLD rats induced high fat diet.

Induction of microRNA-199 by Nitric Oxide in Endothelial Cells Is Required for Nitrovasodilator Resistance via Targeting of Prostaglandin I2 Synthase.

Background: Nitrates are widely used to treat coronary artery disease, but their therapeutic value is compromised by nitrate tolerance, because of the dysfunction of prostaglandin I2 synthase (PTGIS). MicroRNAs repress target gene expression and are recognized as important epigenetic regulators of endothelial function. The aim of this study was to determine whether nitrates induce nitrovasodilator resistance via microRNA-dependent repression of PTGIS gene expression.

MiR-15b-5p Regulates Collateral Artery Formation by Targeting AKT3 (Protein Kinase B-3).

Objective: To identify circulating microRNAs that are differentially expressed in severe coronary heart disease with well or poorly developed collateral arteries and to investigate their mechanisms of action in vivo and in vitro.

Approach And Results: In our study, we identified a circulating microRNA, miR-15b-5p, with low expression that, nevertheless, characterized patients with sufficient coronary collateral artery function. Moreover, in murine hindlimb ischemia model, in situ hybridization identified that miR-15b-5p was specifically expressed in vascular endothelial cells of adductors in sham group and was remarkably downregulated after femoral artery ligation.

[Ultrasonic atomization of Shaduolika and dexamethasone for pain relief in patients with foliate papillitis].

Purpose: To evaluate the effect of ultrasonic atomization of Shaduolika (a traditional Chinese herb), dexamethasone for pain relief in patients with foliate papillitis.

Methods: 84 patients with foliate papillitis were divided into two groups randomly with the single-blind method. Patients in the experimental group were treated with ultrasonic atomization of Shaduolika and dexamethasone, while patients in the control group were treated by taking Niuhuangjiedu tablets (mixed traditional Chinese medicine).
