Aim To investigate the regulatory effects of coenzyme Q10(CoQ10)on blood lipid level and intesti-nal flora abundance in atherosclerotic(As)rats.Methods 24 rats were randomly divided into control group,As group and CoQ10 intervention group.Rats in the As group and CoQ10 intervention group were fed with high-fat chow for 2 weeks,combined with abdominal aortic balloon injury to replicate the As model.CoQ10 was administered by gavage start-ing on the next day of modeling,once daily for 4 weeks.Aortic Movat's staining and lipid levels were used to verify the effect of CoQ10 intervention in As,and the abundance of intestinal flora in intestinal contents was analyzed using met-agenomics.Results Compared with the control group,rat aortic tissues in the As group showed endothelial damage,structural disorganization of the internal elastic plate and inflammatory infiltration,serum triglyceride(TG),total cholester-ol(TC)and low density lipoprotein cholesterol(LDLC)levels were increased,and high density lipoprotein cholesterol(HDLC)levels were decreased.Compared with the As group,the structure of the endothelial cells of the aorta and the structure of the endothelial cells,the internal elastic plates and the smooth muscle cell morphology were relatively regular,serum TC,TG and LDLC levels were decreased,and HDLC levels were increased in the CoQ10 intervention group.Com-pared with the control group,the intestinal bacterial biodiversity in the As group was reduced.At the phylum level,the abundance of the Firmicutes and the Bacteroidetes were down-regulated,whereas that of Proteobacteria was up-regulated.At the genus level,the relative abundance of Lactobacillus,Bacteroides,Akkermansia,Limosilactobacillus,Parabacteroides and Ligilactobacillus was down-regulated,and the relative abundance of Muribaculum was up-regulated.Compared with the As group,CoQ10 intervention restored the biodiversity of the intestinal microbiota in As rats and increased the relative abundance of Firmicutes,Bacteroidetes,Lactobacillus,Bacteroides,Akkermansia,Limosilactobacillus,Parabacteroides and Ligilactobacillus,while reducing the relative abundance of Proteobacteria and Muribaculum(all P＜0.05).Conclusion CoQ10 can regulate blood lipid levels in As rats,upregulate the abundance of beneficial microbiota,downregulate the abun-dance of harmful microbiota,and modulate the diversity of the gut microbiota.

In this study, we employed a combination of genome mining and heteronuclear single quantum coherence (HSQC)-based small molecule accurate recognition technology (SMART) technology to search for fernane-type triterpenoids. Initially, potential endophytic fungi were identified through genome mining. Subsequently, fine fractions containing various fernane-type triterpenoids were selected using HSQC data collection and SMART prediction. These triterpenoids were then obtained through targeted isolation and identification. Finally, their antifungal activity was evaluated. As a result, three fernane-type triterpenoids, including two novel compounds, along with two new sesquiterpenes and four known compounds were isolated from one potential strain, Diaporthe discoidispora. Their structures were elucidated through analysis of high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and nuclear magnetic resonance (NMR) spectroscopic data. The absolute configurations were determined using single-crystal X-ray diffraction analysis and electron capture detector (ECD) analysis. Compound 3 exhibited moderate antifungal activity against Candida albicans CMCC 98001 and Aspergillus niger.

Traumatic brain injury (TBI) is intricately linked to the most severe clinical manifestations of brain damage. It encompasses dynamic pathological mechanisms, including hemodynamic disorders, excitotoxic injury, oxidative stress, mitochondrial dysfunction, inflammation, and neuronal death. This review provides a comprehensive analysis and summary of biomaterial-based tissue engineering scaffolds and nano-drug delivery systems. As an example of functionalized biomaterials, nano-drug delivery systems alter the pharmacokinetic properties of drugs. They provide multiple targeting strategies relying on factors such as morphology and scale, magnetic fields, pH, photosensitivity, and enzymes to facilitate the transport of therapeutics across the blood-brain barrier and to promote selective accumulation at the injury site. Furthermore, therapeutic agents can be incorporated into bioscaffolds to interact with the biochemical and biophysical environment of the brain. Bioscaffolds can mimic the extracellular matrix environment, regulate cellular interactions, and increase the effectiveness of local treatments following surgical interventions. Additionally, stem cell-based and exosome-dominated extracellular vesicle carriers exhibit high bioreactivity and low immunogenicity and can be used to design therapeutic agents with high bioactivity. This review also examines the utilization of endogenous bioactive materials in the treatment of TBI.

Allergic rhinitis (AR), a globally prevalent immune-mediated inflammatory condition, is still an incurable disease. In the present study, we have validated the impact of the Kelch-like ECH associated protein 1 (Keap1)-related oxidative stress and inflammatory response in clinical AR patient peripheral blood and nasal swab samples, emphasizing the biological relevance of Keap1 and AR. Targeting Keap1 -nuclear factor erythroid 2-related factor 2 (Nrf2) related anti-oxidative stress may be effective for AR intervention. Drawing inspiration from the Keap1 homodimerization and the E3 ligase characteristics, we herein present a design of novel bivalent molecules for chemical knockdown of Keap1. For the first time, we characterized ternary complexes of Keap1 dimer and one molecule of bivalent compounds. The best bivalent molecule 8 encompasses robust capacity to degrade Keap1 as a homoPROTAC^KEAP1. It efficaciously suppresses inflammatory cytokines in extensively different cells, including human nasal epithelial cells. Moreover, in an AR mouse model, we confirmed that the chemical degradation induced by homoPROTAC^KEAP1 led to therapeutic benefits in managing AR symptoms, oxidative stress and inflammation. In summary, our findings underscore the efficacy of targeting the Keap1 system through the homoPROTAC-ing technology as an innovative and promising treatment strategy for the incurable allergic disorders.

ObjectiveTo explore the effects of different emulsion mixtures and emulsification methods on the inflammation severity in an experimental autoimmune uveitis （EAU） model in rats， and to analyze the characteristics of the current EAU model. MethodEAU was induced in Lewis rats by subcutaneous injection of interphotoreceptor retinoid-binding protein （IRBP） 1177-1191 emulsified with Freund's complete adjuvant （CFA）， with or without intraperitoneal injection of pertussis toxin （PTX）. Slit lamp examination， HE staining， and optical coherence tomography were used to evaluate factors affecting EAU modeling， including different doses of the emulsion mixture （IRBP1177-1191， PTX， and inactivated Mycobacterium tuberculosis） and four different emulsification methods. The classification， characteristics， modeling methods， advantages， and disadvantages of EAU animal models were summarized and analyzed based on the clinical diagnostic criteria and syndrome characteristics of chronic uveitis in both traditional Chinese medicine （TCM） and western medicine， to evaluate the consistency between TCM and western medical syndromes. ResultIncreasing the dose of inactivated M. tuberculosis and antigen peptide in the emulsion mixture exacerbated the anterior segment inflammation in EAU rats. Increasing the injection of PTX also exacerbated anterior segment inflammation and increased retinal thickness in EAU rats. The severity of the EAU model was closely related to the emulsification method used. All four emulsification methods successfully induced EAU in rats. Comparatively， the ultrasonic cell disruptor and T10 basic disperser achieved successful emulsification in a short time. The degree of emulsification of the mixture also influenced the severity of the EAU model in rats. The existing EAU animal model shows a high degree of consistency with western medical diagnoses and the main ocular syndromes in TCM. ConclusionIRBP1177-1191， PTX， inactivated M. tuberculosis， and emulsification methods can affect the severity of the EAU model through different pathways. The existing EAU animal models can simulate the clinical characteristics of western medicine well but lack the etiology， pathogenesis， and syndrome characteristics of TCM. Therefore， it is necessary to construct an EAU animal model that combines disease and syndrome characteristics.
