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.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

Chronic insomnia affects 10%–15% of the population, with one-third of Western adults struggling with sleep initiation or maintenance. Binaural beats, which involve two audio frequencies, have shown the potential for enhancing sleep and mood. This study examined the efficacy of customized binaural audio tracks generated using facial analysis software to treat chronic insomnia. Methods: A 45-minute personalized binaural beat audio session was delivered using the Spatial app and headband (SoundHealth) to 20 participants with moderate-to-severe insomnia, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and Insomnia Severity Index (ISI) criteria, over four weeks in California. Statistical analysis (paired t-test and linear mixed modeling) was used to compare baseline ISI scores to posttreatment scores, with p<0.05 indicating significance. The study assumed 80% power and aimed to achieve a 7-point ISI reduction. Results: All participants completed the study with no adverse events or full protocol adherence. The cohort was 60% White, with a 3:1 female-to-male ratio and an average age of 51.9 years. The baseline ISI was 19.8, dropping to 8.5 after four weeks, showing an 11.3-point reduction (95% confidence interval [CI]: -15 to -7.6, p<0.001). Mixed modeling indicated a similar ISI decrease of 11.28 points (95% CI: -14.98 to -7.57, p<0.001). The treatment response rate was 70%. Conclusions: Customized binaural beats show promise for insomnia treatment, with no adverse effects and high adherence. Most participants improved to no insomnia or subthreshold insomnia. Further research is needed to validate these results using larger samples and to assess long-term effects.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To establish the phylogenic relationships among genus Botrychium,and to develop better molecular markers,along with to gain better understanding of cytonuclear coordination patterns of RuBisCO enzyme,the current article sampled two species(e.g.Botrychium ternatum(Thunb.)Sw.and Botrychium virginianum(L.)Sw.),and applied sequencing approaches for the data mining.Methods The assembly results of chloroplast(cp)genomes from B.ternatum and B.virginianum were determined via de novo hybrid assemble approach with the help of short reads(Illumina)and long reads(PacBio and Nanopore).Then the phylogenic relationships of 18 fern species were reconstructed based on the protein coding sequences from the cp genome and the rbcS gene,which were fished out of the RNA-seq data from SRA database,respectively.Then the adaptive selection and co-evolutionary analysis were employed to investigate the evolutionary trajectories of rbcL(cp genome)and rbcS(nuclear genome)genes.Results The full length of cp genome in the two genus Botrychium species were determined as 139 063 bp(NC_060644)and 139 372 bp(OR609363).Then 92 SSR sites and 78 SSR sites were identified in the current two cp genomes,respectively.The collinearity analysis showed high relevant relationship between the current two species,and significant relationship within both species among the inverted repeats regions.The adaptation and coevolution investigations illustrated the following results:①Coevolution network exists between RBCL and RBCS subunits from the fern RuBisCO enzyme.②Positively selected sites were significantly detected among both rbcL and rbcS genes.③Two coevolutionary pair sites from the two genes(e.g.site 11 in RBCL and site 106 in RBCS)were significantly positively selected,which may demonstrate a molecular pattern for the fern species fine-tuning the RuBisCO enzyme during the long earth history via the cytonuclear coordination.Conclusion Our current research shed a new light on the phylogenetic relationship of the genus Botrychium among the fern backbone-tree and provided amount of cpSSR sites with the potential as molecular markers for further population study on B.ternatum and B.virginianum.Moreover,our adaptation and coevolution investigations on rbcL and rbcS genes might indicate that the underlying cytonuclear coordination between the organelle and nuclear in cell of fern species for fine-tuning the key photosynthesis enzyme RuBisCO to gain better fitness according to the changing environment of earth during the geologic time-scale.

Objective Five chloroplast(cp)genomes from members of genus Polygonatum were assembled by hybrid assembly technique,and their intraspecic and interspecific differences were analyzed by comparative genomic method.Codon usage patterns and influencing factors were determined,and the cp genome data were applied to understand the phylogenomic relationships in the entire genus Polygonatum along with the available data.Methods In this study,the chloroplast genomes of 5 species of genus Polygonatum were assembled using Unicycler software.Sequence alignment,collinearity analysis,boundary analysis and other methods were used to evaluate the interspecific differences of these five species.Nucleotide polymorphism analysis was used to discover the high-variation sites of the five species and their related species,predict the distribution of different long repeat sequences and SSRs,and then analyze the use bias of Polygonatum code.Finally,phylogenetic tree was constructed with the coding sequences of other 47 genus Polygonatum and their closely related species to explore their phylogenetic relationships in this study.Results ①Chloroplast genomes of 155 408-155 623 bp were assembled from five species of Polygonatum.A total of 132-133 genes were annotated,and 369 long repeats and 1553 simple repeats were detected.②The contraction and expansion of chloroplast genomes in 8 species were not obvious at the IRs boundary,and the size and distribution of individual genes at the LSC-IRs-SSC boundary,such as ndhF gene and ycf1 gene,were slightly different.No interspecific or intraspecific rearrangement was observed in 8 species.③ The high-variation regions of the 8 chloroplast genomes are mainly located in two single-copy regions,the duplicate copy region is relatively conserved,and the coding region is more conserved than the non-coding region.High nucleotide polymorphic loci rps16-trnQ,trnS-trnG,trnTUGU-trnL,ndhF-rpl32 and rpl32-trnL are located in the single copy region and most of them are gene spacer regions.④ The codon preference results showed that the codon preference of the five species was similar and mainly affected by selection pressure,and the third base of the codon played A dominant role and mainly ended in A/U.RSCU clustering heat map shows that PK and PZ,PCB and PS have close relationship.⑤ Phylogenetic trees divided 52 species into five branches:Ⅰ,Ⅱ,Ⅲ,ⅣandⅤ.PS,PK,PCB,PCZ and PZ were divided into ⅣandⅤbranches,among which PK and PZ were most closely related,while PCZ was more distant than the other four,was divided into the Ⅴbranch alone.Conclusion This study provided a reference for the phylogenetic research and molecular marker development of the medicinal plants of the Polygonum genus.

Ferroptosis has been shown to mediate the development of fibrosis.Polyphyllin Ⅶ(PP7),a bioactive component of Paris polyphylla,exhibits potent anti-inflammatory activity and can significantly alleviate liver fibrosis.In this study,treatment with PP7 significantly inhibited the proliferation and activation of hepatic stellate cells(HSCs),which could be suppressed by a ferroptosis inhibitor.In addition,it promoted HSC ferroptosis by suppressing glutathione(GSH)peroxidase 4(GPX4)and enhanced the expression of CX3C chemokine ligand 1(CX3CL1).Depletion of CX3CL1 attenuated the effects of PP7 on the activation and ferroptosis of HSCs and the expression of GPX4.Notably,CX3CL1 directly interacted with GPX4,triggering HSC ferroptosis.The transcription factor hypermethylated in cancer 1(Hic1),which binds to the Cx3cl1 promoter,increased the expression of CX3CL1.Its absence resulted in downregulation of CX3CL1,sup-pressing the GPX4-dependent ferroptosis of PP7-treated HSCs and promoting their activation.HIC1 was found to directly interact with PP7 at the GLY164 site.Co-culture experiments showed that PP7-induced HSC ferroptosis attenuated macrophage recruitment by regulating inflammation-related genes.HSC-specific inhibition of HIC1 counteracted PP7-induced collagen depletion and HSC ferroptosis in vivo.These findings suggest that PP7 induces HSC ferroptosis through the HIC1/CX3CL1/GPX4 axis.
