Extract Alleviates NASH in Mice: Exploration of Inflammation and Gut Microbiota.

NASH (non-alcoholic steatohepatitis) is a severe liver disease characterized by hepatic chronic inflammation that can be associated with the gut microbiota. In this study, we explored the therapeutic effect of extract (GPE), a Chinese herbal extract, on methionine- and choline-deficient (MCD) diet-induced NASH mice. Based on the peak area, the top ten compounds in GPE were hydroxylinolenic acid, rutin, hydroxylinoleic acid, vanillic acid, methyl vanillate, quercetin, pheophorbide A, protocatechuic acid, aurantiamide acetate, and iso-rhamnetin.

Pharmacokinetics, anti-rheumatoid arthritis activity, and active ingredient contents of Eucommia ulmoides Oliv.

Eucommia ulmoides Oliv. is a deciduous tree which contains various chemical ingredients. The main objective was to document the active chemical ingredients of Eucommia ulmoides Oliv.

A detection method of typical toxic mixed red tide algae in Qinhuangdao based on three-dimensional fluorescence spectroscopy.

Red tides occur every year in the Qinhuangdao sea area of China, including a variety of toxic algae and non-toxic algae. Toxic red tide algae have caused great damage to the marine aquaculture industry in China and seriously endangered human health, but most of non-toxic algae are important bait for marine plankton. Therefore, it is very important to identify the type of mixed red tide algae in Qinhuangdao sea area.

polysaccharides ameliorate non-alcoholic steatohepatitis in mice associated with gut microbiota and the TLR2/NLRP3 pathway.

Recent studies have revealed the pivotal role of gut microbiota in the progress of liver diseases including non-alcoholic steatohepatitis (NASH). Many natural herbs, such as (GP), have been extensively applied in the prevention of NASH, while the bioactive components and underlying mechanism remain unclear. The aim of this study was to investigate whether the polysaccharides of GP (GPP) have a protective effect on NASH and to explore the potential mechanism underlying these effects.

Identification of ichthyotoxic red tide algae based on three-dimensional fluorescence spectra and particle swarm optimization support vector machine.

Acccurate identification whether red tide has ithyotoxicity is very significant for microalgae monitoring. In order to realize the rapid and non-destructive detection of ichthyotoxic red tide algae, a detection method combining three-dimensional (3D) fluorescence spectrum and particle swarm optimization support vector machine (PSO-SVM) was developed to monitor the ichthyotoxic red tide algae with cell concentrations from 10 cells/mL to 10 cells/mL. The contour maps contracted form three-dimensional fluorescence spectra of six common species of ichthyotoxic algae and eight common species of non-ichthyotoxic algae,which are analyzed to select the optimal emission and excitation wavelength span.

Cytotoxic Prenylated Xanthones from the Leaves of Garcinia bracteata.

Six new prenylated xanthones (1: -6: ) and seventeen known xanthones were isolated from extracts of leaves. Their structures were determined by extensive NMR and MS spectroscopic data analysis. The inhibitory activities of the isolates were assayed on HeLa, A549, PC-3, HT-29, and WPMY-1 cell lines.

Bioactive scalemic caged xanthones from the leaves of Garcinia bracteata.

Four pairs of previously undescribed caged xanthones (1-4) and twelve known caged xanthones (5-16) were isolated from the leaf extract of Garcinia bracteata. Their structures were unambiguously elucidated on the basis of spectroscopic methods. The planar structure and relative configuration of 1 was confirmed by X-ray crystallographic analysis.

Oblongifolin C and guttiferone K extracted from Garcinia yunnanensis fruit synergistically induce apoptosis in human colorectal cancer cells in vitro.

Oblongifolin C (OC) and guttiferone K (GUTK) are two anticancer compounds extracted from Garcinia yunnanensis Hu, but they act by different mechanisms. In this study we investigated whether a combination of OC and GUTK (1:1 molar ratio) could produce synergistic anticancer effects against human colorectal cancer cells in vitro. For comparison, we also examined the anticancer efficacy of ethanol extracts from G yunnanensis fruit, which contain OC and GUTK up to 5%.

Up-regulation of miR-335 predicts a favorable prognosis in esophageal squamous cell carcinoma.

Introduction: MicroRNAs (miRNAs) are noncoding RNAs that regulate multiple cellular processes during cancer progression. MiR-335 has recently been identified to be involved in tumorigenesis of several cancers such as ovarian cancer and gastric cancer. However, the regulation of miR-335 in esophageal squamous cell carcinoma (ESCC) has not been reported yet.

[Effects of naoxintong capsule on the inflammation and prognosis in borderline lesion coronary heart disease patients].

Objective: To study the effects of Naoxintong Capsule (NC) on the inflammation and long-term prognosis in the borderline lesion coronary heart disease patients.

Methods: A total of 240 coronary heart disease patients with angina symptoms and accompanied with borderline lesion coronary heart disease (with the diameter stenosis in critical 50% -70%) by means of coronary angiography or multislice computed tomography coronary angiography were recruited. These patients were randomly assigned to the conventional treatment group (including nitrate, beta blockers, anti-platelet, anticoagulation, angiotensin converting enzyme inhibitors, and so on) and the NC treatment group (treated the same way as those for the conventional treatment group and NC).

Protective effect of glutathione S-transferase-fused mutant staphylococcal enterotoxin C against Staphylococcus aureus-induced bovine mastitis.

Recent studies have demonstrated that immunization with nontoxic mutant staphylococcal enterotoxin C (mSEC) provides protection against Staphylococcus aureus infection in mouse models. In the present study, we investigated whether vaccination with a glutathione S-transferase-fused SEC (GST-mSEC) can protect against S. aureus-induced bovine mastitis.
