ObjectiveTo investigate the intervention effects and mechanisms of the flavonoid hyperoside （Hyp） on lipopolysaccharide （LPS）-induced inflammation in the zebrafish model. MethodsZebrafish larvae were either microinjected with 0.5 g·L^-1 LPS or immersed in 1 g·L^-1 LPS for the modeling of inflammation. The larvae were then treated with Hyp at 25， 50， and 100 mg·L^-1 through immersion for four consecutive days. The inflammatory phenotypes were assessed by analyzing the mortality rate， malformation rate， body length， and yolk sac area ratio. Behavioral tests were conducted to evaluate the inflammatory stress responses， and macrophage migration was observed by fluorescence microscopy. Additionally， the mRNA levels of inflammation-related genes， including interleukin-1β （IL-1β）， interleukin-6 （IL-6）， chemokine C-C motif ligand 2 （CCL2）， chemokine C-X3-C motif receptor 1 （CX3CR1）， chemokine C-C motif receptor 2 （CCR2）， and genes associated with the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor-kappa B （NF-κB） signaling pathway， were measured by Real-time quantitative polymerase chain reaction（Real-time PCR）. ResultsCompared with the pure water injection group， the model group exhibited increased mortality， malformation rates and yolk sac area ratio （P0.01）， reduced body length （P0.01）， increased total swimming distance and high-speed swimming duration （P0.01）， and up-regulated mRNA levels of TLR4， MyD88， NF-κB， IL-1β， IL-6， CCL2， CX3CR1， and CCR2 （P0.01）. Hyp at low， medium and high doses， as well as aspirin， reduced the mortality and malformation rates （P0.05，P0.01）， increased the body length （P0.05，P0.01）， decreased the yolk sac area ratio （P0.01）， reduced the high-speed swimming duration （P0.01）， and down-regulated the mRNA levels of TLR4， MyD88， NF-κB， IL-1β， IL-6， CCL2， CX3CR1， and CCR2 （P0.05，P0.01） compared with the model group. ConclusionHyp may modulate the TLR4/MyD88/NF-κB pathway to ameliorate inflammatory phenotypes and alleviate stress conditions in zebrafish， thereby exerting the anti-inflammatory effect.

Porcine epidemic diarrhea virus (PEDV) is an intestinal coronavirus that can cause porcine epidemic diarrhea, leading to diarrhea, vomiting, weight loss, and even death in piglets. Due to the diversity of PEDV strains, traditional vaccines are difficult to sustainably and effectively prevent and control PEDV. This article reviews the strategies and mechanisms of active substances in regulating intracellular signaling pathways, viral proteins, and microbial metabolites to enhance the host immune function against PEDV. It emphasizes the prevention of PEDV resistance and the potential harm of PEDV breaking through interspecies barriers to the human society, aiming to provide reliable theoretical support for the development of new antiviral drugs or vaccines.

Objective The aim of this study was to explore the role and mechanism of ferroptosis in SiO2-induced cardiac injury using a mouse model. Methods Male C57BL/6 mice were intratracheally instilled with SiO2 to create a silicosis model.Ferrostatin-1(Fer-1)and deferoxamine(DFO)were used to suppress ferroptosis.Serum biomarkers,oxidative stress markers,histopathology,iron content,and the expression of ferroptosis-related proteins were assessed. Results SiO2 altered serum cardiac injury biomarkers,oxidative stress,iron accumulation,and ferroptosis markers in myocardial tissue.Fer-1 and DFO reduced lipid peroxidation and iron overload,and alleviated SiO2-induced mitochondrial damage and myocardial injury.SiO2 inhibited Nuclear factor erythroid 2-related factor 2(Nrf2)and its downstream antioxidant genes,while Fer-1 more potently reactivated Nrf2 compared to DFO. Conclusion Iron overload-induced ferroptosis contributes to SiO2-induced cardiac injury.Targeting ferroptosis by reducing iron accumulation or inhibiting lipid peroxidation protects against SiO2 cardiotoxicity,potentially via modulation of the Nrf2 pathway.

OBJECTIVE To observe the clinical efficacy of endoscopic type Ⅰ tympanoplasty in patients with chronic suppurative otitis media accompanied by fungal otitis media.METHODS Based on the symptom characteristics of the external auditory canal and tympanic mucosa,80 patients were divided into four groups:dry ear without fungi group,dry ear with fungi group,wet ear without fungi group,and wet ear with fungi group.Record its clinical characteristics.Patients with fungal otitis externa should receive medication treatment during the perioperative period.Failure to heal the tympanic membrane repaired 6 months after surgery,recurrent perforation of the graft,and/or persistent inability to dry the ear are considered repair failures.RESULTS A total of 80 patients were included in this study,and the overall healing rate of the tympanic membrane in the four groups of patients was 98.8％.There was no significant difference in the postoperative tympanic membrane healing rate among the four groups of patients.The postoperative air bone conduction difference in all four groups of patients decreased compared to preoperative levels,but the difference was not statistically significant.CONCLUSION Patients with chronic suppurative otitis media accompanied by fungal otitis media undergoing type Ⅰ tympanoplasty showed no decrease in tympanic membrane healing rate and no significant improvement in efficacy.

Objective:To investigate the clinical value of electronic laryngoscope combined with narrow band imaging（NBI） endoscope and its classification in the diagnosis of vocal cord leukoplakia. Methods:A retrospective analysis was performed on 115 cases of patients treated in the Department of Otolaryngology, Head and Neck Surgery, Nanjing Drum Tower Hospital from September 2020 to November 2022. All 115 cases were diagnosed with vocal cord leukogramma using the electronic laryngoscopy and narrow band imaging endoscopy, followed by pathological examination in the outpatient tissue biopsy. The morphological characteristics of vocal cord leukoplakia and the correlation between narrow band imaging classification and pathological results were investigated. Results:Among 115 cases of vocal cord leukoplakia, 46 cases（40.00%） were diagnosed as benign lesions. Low grade intraepithelial neoplasia occurred in 29 cases（25.22%）. High-grade intraepithelial neoplasia（including carcinoma in situ） occurred in 22 cases（19.13%）. Invasive carcinoma（including suspected invasive carcinoma） was found in 18 cases（15.65%）. There were no statistical differences in the unilateral and bilateral distribution of vocal cord leukoplakia and pathological results（P>0.05）, but there were statistical differences in the size, thickness, lesion uniformity, clear boundary, pre-invasion commissure, symmetry,age over 55 years old, morphological classification, NBI classification and pathological results distribution（P<0.05）. The two-by-two comparison among the three groups of morphological classification（flat type, raised type, rough type） showed that P<0.017 was only compared between flat type and rough type, and P>0.017 was compared between the other two groups. The pairwise comparison among the three groups of NBI classification（Ⅲ, Ⅳ, Ⅴ） was statistically significant（P<0.017）. There was a high correlation between NBI classification and pathological diagnosis, and the correlation coefficient was 0.705（P<0.05）. The risk of high intraepithelial neoplasia and cancerization in type Ⅳ was 9.125 times higher than that in type Ⅲ, and the risk of high intraepithelial neoplasia and cancerization in type Ⅴ was 271.078 times higher than that in type Ⅲ. The area under the curve of morphological classification and NBI classification were 0.672 and 0.896, respectively. Conclusion:There is a high match and correlation between NBI classification and pathological diagnosis. Electronic laryngoscope combined with narrow band imaging endoscope has a high diagnostic value for vocal cord leukoplakia, and a strong predictive ability for malignant leukoplakia.
