Their structures were elucidated by using 1D and 2D NMR data, while the relative and absolute configurations were confirmed by interpretations of the NOESY correlations and comparison of the experimental and calculated ECD spectra. In the evaluation of bioactivities, salviamilthiza C (3), significantly increased cell viability and decreased the expression of IL-1β in LPS-induced BEAS-2B cells.

[Mechanism of "Ephedrae Herba-Descurainiae Semen Lepidii Semen" combination in treatment of bronchial asthma based on network pharmacology and experimental verification].

This study aims to investigate mechanism of "Ephedrae Herba-Descurainiae Semen Lepidii Semen" combination(MT) in the treatment of bronchial asthma based on network pharmacology and in vivo experiment, which is expected to lay a theoretical basis for clinical application of the combination. First, the potential targets of MT in the treatment of bronchial asthma were predicted based on network pharmacology, and the "Chinese medicine-active component-target-pathway-disease" network was constructed, followed by Gene Oncology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the potential targets. Molecular docking was used to determine the binding activity of key candidate active components to hub genes.

Comparative genome anatomy reveals evolutionary insights into a unique amphitriploid fish.

Triploids are rare in nature because of difficulties in meiotic and gametogenic processes, especially in vertebrates. The Carassius complex of cyprinid teleosts contains sexual tetraploid crucian carp/goldfish (C. auratus) and unisexual hexaploid gibel carp/Prussian carp (C.

Ten undescribed diterpenoid quinones derived from the Salvia miltiorrhiza.

This study aimed to report the structure elucidation of the compounds isolated from Salvia miltiorrhiza, and their biological evaluations. Ten undescribed diterpenoid quinones and 10 known analogues were isolated from the dried roots of S. miltiorrhiza.

Risk factors for asthma in patients with allergic rhinitis in eastern China.

Background: Asthma is one of the most common chronic diseases among children and adults and can lead to a high health and socioeconomic burden. Allergic rhinitis (AR) often precedes the development of asthma. This study aims to clarify the risk factors for cocurrent asthma in patients with AR in eastern China.

Glutathione contributes to resistance responses to TMV through a differential modulation of salicylic acid and reactive oxygen species.

Systemic acquired resistance (SAR) is induced by pathogens and confers protection against a broad range of pathogens. Several SAR signals have been characterized, but the nature of the other unknown signalling by small metabolites in SAR remains unclear. Glutathione (GSH) has long been implicated in the defence reaction against biotic stress.

Identification of genetic variants in a pedigree associated with epilepsy by using whole exome sequencing and whole genome sequencing.

Epilepsy is a common heterogeneous group of neurological disorders including electroencephalographic and brain imaging. We used whole exome sequencing and whole genome sequencing to identify variants in a pedigree associated with epilepsy. Cranium CT scan showed that the lateral right parietal lobe was hyperdense, and there were no clear boundaries with brain tissue in affected cases.

Dexmedetomidine alleviates hepatic injury via the inhibition of oxidative stress and activation of the Nrf2/HO-1 signaling pathway.

Dexmedetomidine (Dex), frequently used as an effective sedative, was reported to play a critical role in the protection of multiple organs. However, its underlying mechanism of a putative protective effect on ischemia/reperfusion (I/R)-induced liver injury is still unclear. A hepatocyte injury model was established by treating WRL-68 cells with oxygen and glucose deprivation/reoxygenation (OGD/R).

Systemic administration of the bifunctional opioid/neuropeptide FF receptors agonist BN-9 produced peripheral antinociception in preclinical mouse models of pain.

We recently characterized a novel bifunctional agonist for opioid and neuropeptide FF receptors, named BN-9, which exhibited potent analgesia in the mouse tail-flick test when given centrally. To further evaluate its potential therapeutic efficacy for translational-medical development, the current work was performed to explore the antinociceptive activities of intraperitoneal (i.p.

[Spatial differentiation and impact factors of Yutian Oasis's soil surface salt based on GWR model].

In this paper, topsoil salinity data gathered from 24 sampling sites in the Yutian Oasis were used, nine different kinds of environmental variables closely related to soil salinity were selec-ted as influencing factors, then, the spatial distribution characteristics of topsoil salinity and spatial heterogeneity of influencing factors were analyzed by combining the spatial autocorrelation with traditional regression analysis and geographically weighted regression model. Results showed that the topsoil salinity in Yutian Oasis was not of random distribution but had strong spatial dependence, and the spatial autocorrelation index for topsoil salinity was 0.479.

Etanercept decreases HMGB1 expression in dorsal root ganglion neuron cells in a rat chronic constriction injury model.

In the present study, we examined the effect of etanercept on high mobility group box 1 (HMGB1) expression in dorsal root ganglion (DRG) neuron cells in a rat model of chronic constriction injury (CCI) of the sciatic nerve, with the aim of exploring the molecular mechanism underlying the therapeutic effect of etanercept on sciatica-related nociception and the potential interaction between tumor necrosis factor-α (TNF-α) and HMGB1 in DRG neuron cells. A rat CCI model was employed and the animals were randomly assigned to seven groups (n=20/group): untreated, sham only, sham/saline, sham/etanercept, CCI only, CCI/saline and CCI/etanercept. Our results revealed that compared with the sham/saline and sham/etanercept groups, thermal hyperalgesia and mechanical hyperalgesia, as well as HMGB1 expression at both the mRNA and protein levels in the DRG neuron cells, were induced by CCI, and were significantly inhibited by etanercept.

Single nucleotide polymorphisms of the IL28B and sustained virologic response of patients with chronic hepatitis C to PEG-interferon/ribavirin therapy: A meta-analysis: Meta-analysis of IL28B.

Background: Hepatitis C is a global health problem and represents a major cause of liver disease and socioeconomic burden. Effective antiviral therapy may prevent these complications, but the current treatment for patients with chronic hepatitis C virus (HCV) infection does not produce sustained virologic response. Therefore, identification of the determinants of response to treatment is a high priority.
