Silencing of circARHGAP12 inhibits the progression of atherosclerosis via miR-630/EZH2/TIMP2 signal axis.

Atherosclerosis (AS) is a common disease that seriously threatens human health. So far, the pathogenesis of AS has not been fully understood. This project investigates the effects of circARHGAP12 on AS and its regulatory mechanism.

MicroRNA-130a regulates neurological deficit and angiogenesis in rats with ischaemic stroke by targeting XIAP.

MicroRNAs (miRNAs) have already been proposed to be implicated in the development of ischaemic stroke. We aim to investigate the role of miR-130a in the neurological deficit and angiogenesis in rats with ischaemic stroke by regulating X-linked inhibitor of apoptosis protein (XIAP). Middle cerebral artery occlusion (MCAO) models were established by suture-occluded method, and MCAO rats were then treated with miR-130a mimics/inhibitors or/and altered XIAP for detection of changes of rats' neurological function, nerve damage and angiogenesis in MCAO rats.

Exosomes derived from oxLDL-stimulated macrophages induce neutrophil extracellular traps to drive atherosclerosis.

This study aimed to investigate the role and underlying mechanism of exosomes secreted by oxidized low-density lipoprotein (oxLDL)-stimulated macrophages in the progression of atherosclerosis (AS). Exosomes from peripheral blood of AS patients or oxLDL-treated macrophages were co-cultured with human neutrophils. Neutrophil extracellular traps (NETs) were detected by immunofluorescence staining.

LncRNA DIGIT Accelerates Tube Formation of Vascular Endothelial Cells by Sponging miR-134.

Atherosclerosis is one of the most prevalent and important cardiac diseases, involving the heart and brain. This study aimed to explore the impacts of lncRNA Divergent to GSC induced by TGF-b family signaling (DIGIT) on vascular endothelial cells tube-formation capacity so as to reveal the potentials of DIGIT in atherosclerosis therapy. DIGIT expression in human microvascular endothelial HMEC-1 cells was silenced by transfection with shRNAs-targeted DIGIT.

Volatile organic compound emissions from straw-amended agricultural soils and their relations to bacterial communities: A laboratory study.

A laboratory study was conducted to investigate volatile organic compound (VOC) emissions from agricultural soil amended with wheat straw and their associations with bacterial communities for a period of 66days under non-flooded and flooded conditions. The results indicated that ethene, propene, ethanol, i-propanol, 2-butanol, acetaldehyde, acetone, 2-butanone, 2-pentanone and acetophenone were the 10 most abundant VOCs, making up over 90% of the total VOCs released under the two water conditions. The mean emission of total VOCs from the amended soils under the non-flooded condition (5924ng C/(kg·hr)) was significantly higher than that under the flooded condition (2211ng C/(kg·hr)).

Effects of integrin α5β1 on the proliferation and migration of human aortic vascular smooth muscle cells.

Integrin (ITG) α5β1 is a dominant fibronectin receptor that is abundantly expressed on the surface of vascular smooth muscle cells (VSMCs). However, the association between integrin α5β1 and the proliferation and migration of VSMCs has yet to be elucidated. The aim of the present study was to characterize the roles of ITGα5 and ITGβ1 in the proliferation and migration of VSMCs, and to determine the effects of ITGα5β1 on integrin-linked kinase (ILK) and focal adhesion kinase (FAK) mRNA expression.

Diagnosis and Treatment of Vascular Surgery Related Infection.

Surgical site infection (SSI) is an important component of infections acquired from hospital. The most significant feature of vascular surgery different from other surgeries is frequent application of artificial grafts. Once SSI occurs after vascular operations with grafts, it might results in a serious disaster.

Report: Analysis on pathogen distribution and drug-resistance of incision infection caused by vascular operation.

To investigate pathogen distribution and drug resistance of incision infection caused by vascular operation to reduce postoperative incision infection, this paper retrospectively reviewed and analyzed 635 in-hospital patients taking vascular operation during Jan. 2008 and Dec. 2012.

[Influence of DNA methyltransferase 3b on the expression of cyclin D1 gene and methylation of its promoters in human hepatocellular carcinoma cells].

Objective: To investigate the influence of DNA methyltransferase (DNMT) 3b on the expression of cyclin D1 gene and methylation of its promoters and to investigate the function of DNMT3b.

Methods: Human hepatocellular carcinoma cells of the line SMMC7721 were cultured and randomly divided into 3 groups: experimental group transfected with siRNA to silence the DNMT3b, control group transfected with control siRNA, and normal group without transfection. The transfection rate of siRNA was detected by fluorescence microscopy.

Influence of DNA methyltransferase 3b on FHIT expression and DNA methylation of the FHIT promoter region in hepatoma SMMC-7721 cells.

Background: Alterations in DNA methylation occur during the pathogenesis of human tumors. In this study, we investigated the influence of DNA methyltransferase 3b (DNMT3b) on fragile histidine trial (FHIT) expression and on DNA methylation of the FHIT promoter region in the hepatoma cell line SMMC-7721.

Methods: DNMT3b siRNA was used to down-regulate DNMT3b expression.
