ObjectiveNonalcoholic fatty liver disease (NAFLD) is a metabolic stress liver injury. Ferroptosis is involved in the occurrence and development of NAFLD. Exploring the efficacy and mechanism of schisandrin B in treating NAFLD facilitates the development of strategies for the prevention and treatment of NAFLD. MethodsThe molecular structure of schisandrin B was obtained by searching against PubChem, and the related targets were predicted by SwissTargetPrediction. The active ingredients and their targets were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the high-throughput experiment- and reference-guide database of traditional Chinese medicine (HERB). GeneCards and FerrDb were searched for the targets of NAFLD and ferroptosis. The common targets were taken as the core targets, and the protein-protein interaction network of the core targets was established. DAVID was used for gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. Finally, molecular docking was performed between schisandrin B and core targets, and the binding energy was calculated. C57BL/6 mice were fed with a methionine and choline-deficiency (MCD) diet for the modeling of NAFLD. Mice were randomized into normal, model, positive drug (essentiale), and low- and high-dose schisandrin B groups. The body mass and liver index of mice were measured after drug administration. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum and those of total cholesterol (TC), triglyceride (TG), malondialdehyde (MDA), glutathione (GSH), and Fe2+ in the liver homogenate were measured by biochemical assay kits. The pathological changes of the liver tissue were observed by hematoxylin-eosin (HE) and red oil O staining. Enzyme-linked immunosorbent assay was employed to determine the levels of interleukin (IL)-6, IL-1β, tumor necrosis factor (TNF)-α, and 4-hydroxynonenal (4-HNE) in the serum. Western blotting and real-time PCR were employed to determine the protein and mRNA levels, respectively, of solute carrier family 7 member 11 (SLC7A11), solute carrier family 3 member 2 (SLC3A2), glutathione peroxidase 4 (GPX4), transferrin, and ferritin heavy chain (FTH) in the liver tissue. ResultsA total of 2 370, 2 547, and 1 451 targets of schisandrin B, NAFLD, and ferroptosis were obtained, in which 90 common targets were shared by the three. Enrichment analyses predicted 505 GO terms and 92 KEGG pathways. Molecular docking suggested that schizandrin B had strong binding affinity with the key targets of ferropstosis (SLC7A11 and SLC3A2). Animal experiments showed that schizandrin B significantly decreased the liver index, lowered the levels of ALT, AST, TC, TG, IL-6, IL-1β, and TNF-α, alleviated hepatocyte ballooning and inflammatory cell infiltration, and reduced lipid accumulation in the liver of NAFLD mice. In addition, schisandrin B significantly lowered the levels of MDA, 4-HNE, and Fe2+, elevated the level of GSH, up-regulated the protein and mRNA levels of SLC7A11, SLC3A2, and GPX4, and down-regulated the protein and mRNA levels of transferrin in the liver tissue. ConclusionSchisandrin B can alleviate NAFLD by inhibiting ferroptosis in hepatocytes.

ObjectiveTo explore the mechanism of action of Wendantang on ApoE-/- hyperlipidemic mice using non-targeted metabolomics technology. MethodsMale C57BL/6J mice served as the normal control group (n=6), and they were fed with regular chow, while male ApoE-/- mice constituted the high-fat group (n=30), and they were fed with a 60% high-fat diet. After 11 weeks of model establishment, the mice in the high-fat group were randomly divided into the model group, simvastatin group (3.3 mg·kg-1), and high-dose, medium-dose, and low-dose groups of Wendantang (26, 13, 6.5 g·kg-1, respectively, in terms of crude drug amount), with six mice in each group. The normal control group and the model group were gavaged with an equivalent volume of normal saline, and all groups continued to be fed their respective diets, receiving daily medication for 10 weeks with weekly body weight measurements. Serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), free fatty acids (NEFA), blood glucose (GLU), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected in the mice. Pathological changes in liver tissue were observed using hematoxylin-eosin (HE) staining, and ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) was employed for metabolomic analysis of mouse liver tissue. ResultsCompared to the normal control group, the model group exhibited significantly increased body weight, blood lipid levels, and liver function (P<0.05, P<0.01), with disordered liver tissue structure, swollen hepatocytes, and accompanying vacuolar fatty degeneration and inflammatory cell infiltration. Compared to the model group, the simvastatin group and Wendantang groups showed significantly reduced body weight, TG, NEFA, GLU, ALT, and AST levels (P<0.05, P<0.01), with a significant increase in HDL-C levels (P<0.05, P<0.01), demonstrating a dose-dependent effect. The lesion of the liver tissue section was obviously improved after administration, tending towards a normal liver tissue morphology. Analysis of liver metabolites revealed 86 differential metabolites between the normal control group and the model group, with the high-dose group of Wendantang able to regulate 56 of these metabolites. Twenty-two differential metabolites associated with hyperlipidemia were identified, mainly including chenodeoxycholic acid, hyocholic acid, taurine, glycocholic acid, dihydroceramide, hydroxy sphingomyelin C14∶1, arachidonic acid, and linoleic acid, enriching 22 metabolic pathways, with 4 being the most significant (P<0.05), namely primary bile acid biosynthesis, sphingolipid metabolism, unsaturated fatty acid biosynthesis, and linoleic acid metabolism pathways. ConclusionWendantang can improve blood lipid levels and liver function in ApoE-/- hyperlipidemic mice, which may be related to the regulation of primary bile acid biosynthesis, sphingolipid metabolism, unsaturated fatty acid biosynthesis, and linoleic acid metabolism pathways.

Objective:To explore the mediating role of disease progression′s fear and positive affect in the relationship between disease perception and demoralization in patients with chronic heart failure. It provided a theoretical basis for targeted interventions for healthcare workers.Methods:From October 2022 to March 2023, 320 patients with chronic heart failure in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by convenience sampling. The General Information Questionnaire, Demoralization Scale Redacted Mandarin Version, Brief Illness Perception Questionnaire, Fear of Progression Questionnaire-Short Form, Positive and Negative Affect Schedule (Positive Affect Schedule) were used to conduct the questionnaire survey exploring the mediating effects of fear of disease progression and positive emotions between disease perception and disorientation by construction structural equation model.Results:There were 268 valid questionnaires. Of the 268 patients, 168 were male and 100 were female, 3.36% (9/268) were ≤40 years old, 55.22% (148/268) were 41-65 years old, and 41.42% (111/268) were >65 years old. Correlation analysis showed that disease perception was positively correlated with disease progression ′s fear, and every dimension of demoralization ( r values were 0.300-0.586, all P<0.01), and negatively correlated with positive affect ( r=-0.374, P<0.01); disease progression′s fear was negatively correlated with positive affect ( r=-0.318, P<0.01), and positively correlated with every dimension of demoralization ( r values were 0.339-0.464, all P<0.01); positive affect was negatively correlated with every dimension of demoralization ( r values were -0.430--0.334, all P<0.01). Structural equation model analysis showed that the direct effect of disease perception on demoralization was significant ( β=0.407, P<0.01), and both mediating effects of disease progression ′s fear and positive affect between disease perception and demoralization in patients with chronic heart failure were significant ( β=0.074, 0.079, both P<0.01). The chain mediating effect of disease progression ′s fear and positive effect was also significant ( β=0.019, P<0.01). Conclusions:Disease perception could directly predict the demoralization of patients with chronic heart failure and indirectly predict the demoralization of patients with chronic heart failure through the mediating effect of disease progression ′s fear, positive affect, and the chain mediating effect of disease progression ′s fear and positive affect.

Insomnia is the second most common psychiatric disorder in clinical practice, and more than one-third of adults may experience different forms of insomnia during their lifetime, but the root causes behind insomnia need further clarification. Early evidences from twins and family studies had shown that insomnia can be attributed to genetics. In recent years, with the rapid development of gene sequencing technology, Nature Genetics had published several consecutive articles focusing on insomnia and genes, confirming that genetic factors played an important role in the occurrence and development of insomnia. Therefore, the recent research progresses on insomnia and circadian rhythm, cytokines, neurotransmitters, and other related genes were summarized in this review, which could help to understand the pathogenesis of insomnia and develop precise treatment strategies.
