Integrated UPLC-ESI-MS/MS, network pharmacology, and transcriptomics to reveal the material basis and mechanism of Schisandra chinensis Fruit Mixture against diabetic nephropathy.

Backgrounds: It has been regarded as an essential treatment option for diabetic nephropathy (DN) in Traditional Chinese medicine. Previous studies have demonstrated the anti-DN efficacy of Schisandra chinensis Fruit Mixture (SM); however, a comprehensive chemical fingerprint is still uncertain, and its mechanism of action, especially the potential therapeutic targets of anti-DN, needs to be further elucidated.

Objective: Potential mechanisms of SM action on DN were explored through network pharmacology and experimental validation.

Mollugin Derivatives as Anti-Inflammatory Agents: Design, Synthesis, and NF-κB Inhibition.

Nuclear factor κB (NF-κB) is a key inducible transcription factor that controls a large number of genes involved in inflammatory and immune processes. The entire inflammation-mediated process uses NF-κB as a hub, and inflammatory gene transcription and expression can be decreased by blocking the NF-κB signaling pathway, thereby reducing inflammatory damage. Therefore, the inhibition of this pathway is an important therapeutic target for the treatment of various types of inflammation.

Design, Synthesis, and Hypoxia-Inducible Factor-1α Inhibitory Activity Evaluation of Panaxadiol Derivatives Containing a Thiazole Moiety.

The hypoxia-inducible factor-1α (HIF-1α) pathway has been implicated in tumor angiogenesis, growth, and metastasis. Therefore, the inhibition of this pathway is an important therapeutic target for cancer. Thiazole derivatives have been reported to have diverse biological activities, especially in terms of anti-tumor.

Zonisamide attenuates pressure overload-induced myocardial hypertrophy in mice through proteasome inhibition.

Myocardial hypertrophy is a pathological thickening of the myocardium which ultimately results in heart failure. We previously reported that zonisamide, an antiepileptic drug, attenuated pressure overload-caused myocardial hypertrophy and diabetic cardiomyopathy in murine models. In addition, we have found that the inhibition of proteasome activates glycogen synthesis kinase 3 (GSK-3) thus alleviates myocardial hypertrophy, which is an important anti-hypertrophic strategy.

Ependyma in Neurodegenerative Diseases, Radiation-Induced Brain Injury and as a Therapeutic Target for Neurotrophic Factors.

The neuron loss caused by the progressive damage to the nervous system is proposed to be the main pathogenesis of neurodegenerative diseases. Ependyma is a layer of ciliated ependymal cells that participates in the formation of the brain-cerebrospinal fluid barrier (BCB). It functions to promotes the circulation of cerebrospinal fluid (CSF) and the material exchange between CSF and brain interstitial fluid.

[Effects of Different Carbon Inputs on Soil Stoichiometry in Tianshan Mountains].

Soil C, N, and P elements are important components of the forest ecosystem. Studying the influence of exogenous carbon input change on the stoichiometry of the forest soil can reveal the element recycling process and the balanced feedback mechanism of the forest ecosystem. In this study, using the research object of a spruce forest in Tianshan Mountain, the short-term effect of exogenous carbon input on soil C, N, and P in the soil was analyzed through Detritus Input and Removal Treatment (DIRT), and then the interrelationship between soil stoichiometry and other soil physicochemical factors under different treatments was discussed.

A bacteriocyte symbiont determines whitefly sex ratio by regulating mitochondrial function.

Nutritional symbionts influence host reproduction, but the underlying molecular mechanisms are largely unclear. We previously found that the bacteriocyte symbiont Hamiltonella impacts the sex ratio of the whitefly Bemisia tabaci. Hamiltonella synthesizes folate by cooperation with the whitefly.

[Silk fibroin/collagen composite hydrogels with different matrix stiffness influence the growth and phenotype of human mammary epithelial cells].

Extracellular matrix (ECM) stiffness is closely related to the physiological and pathological states of breast tissue. The current study was aimed to investigate the effect of silk fibroin/collagen composite hydrogels with adjustable matrix stiffness on the growth and phenotype of normal breast epithelial cells. In this study, the enzymatic reaction of horseradish peroxidase (HRP) with hydrogen peroxide (HO) was used to change the degree of cross-linking of the silk fibroin solution.

Vaccarin enhances intestinal barrier function in type 2 diabetic mice.

Aims: Hyperglycemia and insulin resistance drive intestinal barrier dysfunction in type 2 diabetes (T2DM). Vaccarin, the main active component in the semen of traditional Chinese medicine Vaccaria has a definite effect on T2DM mice. The purpose of this study was to investigate whether vaccarin can enhance the intestinal barrier function in T2DM.

[Identification of Hub Genes for Ovarian Cancer Stem Cell Properties with Weighted Gene Co-expression Network Analysis].

Objective: To investigate the significance of stemness-related genes in the diagnosis and treatment of ovarian cancer.

Methods: Key modules and genes were identified with weighted gene co-expression network analysis (WGCNA). The signal pathways of high expression of key genes were analyzed by gene set enrichment analysis (GSEA) and single cell sequencing data.

[Sediment Pollution Characteristics and Dredging in the Nanfei River Estuary, Chaohu Lake].

To clarify the endogenous pollution characteristics of sediments in the Nanfei River estuary, Chaohu Lake, and provide a theoretical basis for the dredging works, the organic index, pollution index, and potential ecological risk were determined. The results show that the average total nitrogen (TN), total phosphorus (TP), and organic matter (OM) content of the sediment was 1461 mg·kg, 438 mg·kg, and 1.77%, respectively, showing enrichment in the surface layer (0-10 cm).

Survey of antibiotic use among hospitalised children in a hospital in Northeast China over a 4-year period.

Purpose: We investigated the usage of antibiotic utilisation rate (AUR) among Chinese hospitalised children over a 4-year period to determine clinical characteristics.

Design And Methods: AUR, antibiotic type and antibiotic use in combination were analysed among hospitalised children of the affiliated hospital of Beihua University in Northeast China from January 2015 to December 2018. The linear prediction was used to investigate the trends of antibiotics use in combination and AUR, and autoregressive integrated moving average model was used to predict AUR in 2019.

LncRNA-ANRIL inhibits cell senescence of vascular smooth muscle cells by regulating miR-181a/Sirt1.

Background: Cardiovascular disease is one of the major threats to human life and health, and vascular aging is an important cause of its occurrence. Antisense non-coding RNA in the locus (ANRIL) is a kind of long non-coding RNA (lncRNA) that plays important roles in cell senescence. However, the role and mechanism of ANRIL in senescence of vascular smooth muscle cells (VSMCs) are unclear.
