DNAzyme-mediated fluorescence signal variation of DNA-Ag nanoclusters and construction of an aptasensor for ATP.

DNA-templated silver nanoclusters (DNA-AgNCs) are novel nanomaterials with unique fluorescence characteristics. DNAzyme is a functional oligonucleotide that can catalyze the disruption of nucleic acid substrates. In this research, the effect of DNAzyme digestion on the fluorescence property of DNA-AgNCs was explored for the first time.

JiaGaSongTang improves chronic cholestasis via enhancing FXR-mediated bile acid metabolism.

Background: Bile acid (BA) enterohepatic circulation disorders are a main feature of chronic cholestatic diseases. Promoting BA metabolism is thus a potential method of improving enterohepatic circulation disorders, and treat enterohepatic inflammation, oxidative stress and fibrosis due to cholestasis.

Purpose: To investigate the effect of JiaGaSongTang (JGST) and its blood-absorbed ingredient 6-gingerol on α-naphthylisothiocyanate (ANIT)-induced chronic cholestasis, as well as elucidate the underlying regulatory mechanism.

Aqueous extract of Paeoniae Radix Rubra prevents deep vein thrombosis by ameliorating inflammation through inhibiting GSK3β activity.

Background: Deep vein thrombosis (DVT) is a kind of blood stasis syndrome. Paeoniae Radix Rubra (PRR) has long been widely used for eliminating blood stasis in China, but its effect on DVT has not yet been reported.

Purpose: The present study aimed to assess the potential inhibitory effect of the aqueous extract of PRR (i.

A portable and quantitative detection of microRNA-21 based on cascade enzymatic reactions with dual signal outputs.

MicroRNAs (miRNAs) are physiological status-related molecules which can be used as biomarkers for diseases, such as cancers. The point-of-care testing (POCT) of miRNAs has great application potential in early diagnosis and process monitoring of diseases. In this paper, a fast and dual signal outputs detection for microRNA-21 (miRNA-21) was established by using both personal glucose meter (PGM) and fluorescence spectrometer.

Aqueous extract of Whitmania pigra Whitman ameliorates ferric chloride-induced venous thrombosis in rats via antioxidation.

Whitmania pigra Whitman (W. pigra) has been widely employed in decoction for the treatment of blood stasis syndrome for many years in China. The aim of the present study was to explore the anti-venous thrombosis (VT) mechanism of the aqueous extract of W.

Naringenin protects RPE cells from NaIO-induced oxidative damage in vivo and in vitro through up-regulation of SIRT1.

Background: Dry age-related macular degeneration (dAMD) leads to serious burden of visual impairment and there is no definitive treatment. Previous studies have showed that naringenin (NAR) significantly increased electroretinography (ERG) c-wave in sodium iodate (NaIO)-treated rats and viability of NaIO-treated ARPE-19 cells. But the underlying mechanism is still unknown.

Spatholobi Caulis dispensing granule reduces deep vein thrombus burden through antiinflammation via SIRT1 and Nrf2.

Background: Deep vein thrombosis (DVT) is a kind of blood stasis syndrome. Spatholobi Caulis (SC) has been widely used for the treatment of blood stasis syndrome in China, but the underlying mechanism remains poorly understood.

Purpose: The aim of present study was to investigate the anti-DVT mechanism of Spatholobi Caulis dispensing granule (SCDG).

Inferior vena cava stenosis-induced deep vein thrombosis is influenced by multiple factors in rats.

Background: The pathogenesis of deep vein thrombosis (DVT) is incompletely understood, requiring reliable animal models. Inferior vena cava (IVC) stenosis model mimics human DVT.

Objective: To provide optimal conditions for establishing a rat model of IVC stenosis-induced DVT.

miR-130a alleviates neuronal apoptosis and changes in expression of Bcl-2/Bax and caspase-3 in cerebral infarction rats through PTEN/PI3K/Akt signaling pathway.

Effect of micro ribonucleic acid (miR)-130a on neuronal apoptosis in rats with cerebral infarction (CI) was studied to explore whether phosphatase and tensin homolog deleted on chromosome ten (PTEN)/phosphatidylinositol 3-hydroxy kinase (PI3K)/protein kinase B (Akt) is involved in the regulation of neuronal apoptosis. Thirty-six Sprague-Dawley (SD) rats were randomly divided into blank control group, model group and miR-130a low-expression group. miR-130a was determined by quantitative polymerase chain reaction (qPCR), the content of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-10 was detected using the enzyme-linked immunosorbent assay (ELISA) kits, and the neuronal apoptosis level in each group was determined through terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining.

Downregulated miRNA-324-5p aggravates neuronal injury induced by oxygen-glucose deprivation via modulating RAN.

Differentially expressed miRNAs in the GEO profile of ischemic stroke were analyzed to clarify the specific role of microRNA-324-5p (miRNA-324-5p) in ischemic stroke and the potential mechanism. After screening out miRNA-324-5p, its level in peripheral blood of stroke patients and oxygen-glucose deprivation (OGD)-induced primary rat neurons was determined by quantitative real-time polymerase chain reaction (qRT-PCR). Regulatory effects of miRNA-324-5p on viability, and apoptosis of OGD-induced neurons were evaluated by CCK-8 and Annexin V fluorescein isothiocyanate (FITC)/propidium iodide (PI) staining, respectively.

Protective Effects of Li-Fei-Xiao-Yan Prescription on Lipopolysaccharide-Induced Acute Lung Injury via Inhibition of Oxidative Stress and the TLR4/NF-B Pathway.

Li-Fei-Xiao-Yan prescription (LFXY) has been clinically used in China to treat inflammatory and infectious diseases including inflammatory lung diseases. The present study was aimed at evaluating the potential therapeutic effects and potential mechanisms of LFXY in a murine model of lipopolysaccharide- (LPS-) induced acute lung injury (ALI). In this study, the mice were orally pretreated with LFXY or dexamethasone (positive drug) before the intratracheal instillation of LPS.

Polydatin attenuates d-galactose-induced liver and brain damage through its anti-oxidative, anti-inflammatory and anti-apoptotic effects in mice.
