Patulous eustachian tube（PET） is an otolaryngological disorder caused by various factors, characterized by the loss of normal closure function of the eustachian tube in a resting state, resulting in persistent patency. Surgical treatment is recognized as an effective method for the management of refractory PET, but the surgical approaches for PET are diverse, with therapeutic outcomes varying significantly. The surgical procedure involving the occlusion of the tympanic ostium of the eustachian tube through the tympanic membrane, using specially designed silicone plugs, has shown excellent therapeutic outcomes. This minimally invasive procedure is considered highly safe and is considered as the preferred surgical option for patients with refractory PET. The purpose of this article is to review the current status and progress of endoscopic trans-tympanic eustachian tube plug implantation surgery in the treatment of patulous eustachian tube syndrome.

Age-related macular degeneration (AMD) represents a predominant cause of blindness among older adults, with limited therapeutic options currently available. Oxidative stress, inflammation, and retinal pigment epithelium injury are recognized as key contributors to the pathogenesis of AMD. Regulated cell death plays a pivotal role in mediating cellular responses to stress, maintaining tissue homeostasis, and contributing to disease progression. Recent research has elucidated several regulated cell death pathways-such as apoptosis, ferroptosis, pyroptosis, necroptosis, and autophagy-that may contribute to the progression of AMD owing to cell death in the retinal pigment epithelium. These discoveries open new avenues for therapeutic interventions in patients with AMD. In this review, we provide a comprehensive summary and analysis of the latest advancements regarding the relationship between regulated cell death and AMD. Moreover, we examined the therapeutic potential of targeting regulated cell death pathways for the treatment and prevention of AMD, highlighting their roles as promising targets for future therapeutic strategies.

In addition to providing energy for cells, mitochondria also participate in calcium homeostasis, cell information transfer, cell apoptosis, cell growth and differentiation. Therefore, maintaining mitochondrial homeostasis is very crucial for the body to carry out normal life activities. Ubiquitination, a post-translational modification of proteins, is involved in various physiological and pathological processes of cells by regulating mitochondrial homeostasis. However, the mechanism by which ubiquitination regulates mitochondrial homeostasis has not been summarized, especially the effect of Parkin protein on cardiovascular diseases. In this paper, the specific mechanism of mitochondrial homeostasis regulated by ubiquitination of Parkin protein is discussed, and the influence of mitochondrial homeostasis imbalance on cardiovascular diseases is reviewed, with a view to providing potential therapeutic strategies for the clinical treatment of cardiovascular diseases.

Metal-organic frameworks (MOFs) are crystalline materials with a multidimensional porous network structure, formed through coordination bonds with metal ions as nodes and organic ligands as connecting bridges.

Nanoscale metal-organic frameworks (nMOFs), commonly utilized drug carriers, can gain enhanced safety, targeted delivery, and superior therapeutic effect through endocytosis. In this review, we comprehensively summarize the factors influencing the endocytosis of nMOFs, focusing on three key physicochemical properties, particle size, morphology and surface modification. Based on different illness models, the review succinctly summarizes the latest advancements in understanding the endocytosis pathways of nMOFs while critically reflecting on the inherent limitations of current research methods. Lastly, the review offers valuable insights into future research methodologies and objectives, aiming to lay the groundwork and provide meaningful guidance for the synthesis and development of nMOFs as promising versatile drug carriers.

Objective:To explore the effects of hinokiol on the cell cyle and apoptosis of CNE1 nasopharyngeal carcinoma cells and the relevant molecular mechanism.Methods:The CNE1 cells were cultured in vitro and incubated with different concentrations of honokiol, and the cells were divided into blank control group, 10 μmol/L, 20 μmol/L and 40 μmol/L hinokiol treatment groups, and 10 μg/ml cisplatin group. Cell viability was determined by methylthiazolyldiphenyl- tetrazolium bromide (MTT) method, the cell cycle distribution was detected by flow cytometry, mitochondrial membrane potential was detected by mitochondrial membrane potential test kit, apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) method, and the proteins expression of proliferating cell nuclear antigen (PCNA) and G 1/S specific cyclin D1 (cyclin D1) were detected by immunoblotting. RNA-Seq was conducted in the hinokiol-treated cells. The mRNA expression of yes-associated protein delta (YAP) was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). The proteins expression of phosphor-YAP (p-YAP) and nuclear YAP were detected by immunoblotting, the nuclear distribution of YAP protein was detected by immunofluorescence in the cells with or without treated with the mammalian STE20-like kinase 1/2 (MST1/2) inhibitor (XMU-MP-1), hinokiol, and XMU-MP-1+hinokiol. Statistical analysis of the data was conducted using GraphPad Prism 8.0 software. Resluts Compared with the control group, the cell viablity of CNE1 cells, the levels of mitochondrial membrane potential, the proteins expression of PCNA and cyclin D1 in hinokiol treatment groups were markedly decreased (all P values<0.05), while the proportion of G 0/G 1 phase cells and the ratio of TUNEL-positive cells were significantly increased (both P values<0.05). Transcriptome analysis showed that differential genes were mainly enriched in Wnt signaling pathway, tumor necrosis factor pathway, and Hippo signaling pathway. The mRNA level of YAP and the protein expression of YAP in the nucleus were decreased and the level of p-YAP protein was increased in cells treated with hinokiol, which were significantly different from control group (all P values<0.05). Compared with the hinokiol group, XMU-MP-1+hinokiol groups showed the decrease of p-YAP protein expression (1.157±0.076 vs 0.479±0.038, t=37.120, P<0.05), the increase of YAP protein expression in the nucleus (0.143±0.012 vs 0.425±0.031, t=29.181, P<0.05), the reduced proportion of cells in G 0/G 1 phase [(72.494±3.309)% vs (58.747±2.865)%, t=17.265, P<0.05], and the decrease of apoptosis ratio [(53.158±3.376)% vs (29.621±2.713)%, t=28.584, P<0.05]. Conclusion:Hinokiol can arrest the cell cycle and induce the cell apoptosis of CNE1 cells via Hippo/YAP signaling pathway.

The aim of this study was to investigate the virulence determinants and genetic diversity of foodborne Yersinia enterocolitica from Wenzhou.A total of 71 strains of Yersinia enterocolitica were isolated from food and foodborne diarrhea ca-ses in Wenzhou,and their biotypes,serotypes,and drug resistance were analyzed.On the basis of whole genome sequencing,we assessed virulence gene profiles,and performed multilocus sequence typing(MLST)and core gene multilocus sequence typ-ing(cgMLST).A total of 94.4％(67/71)of isolates belonged to biotype 1A,and the highest proportion had serotype lA/O∶5(29.6％,21/71).The sensitivity rates of the isolates to 14 antibiotics exceeded 95.8％.A total of 16 categories and 126 viru-lence genes were identified,with two strains carrying the pYV plasmid and chromosome-related virulence genes.ST3(31.6％,12/38)was the most widespread MLST type,and cgMLST analysis revealed no dense clusters of genotypes except for strains sharing the same ST.In conclusion,pathogenic strains were identified from foodborne Yersinia enterocolitica in Wenzhou and were found to exhibit high genetic polymorphism.Enhanced regulatory supervision is essential to prevent the outbreak of food-borne diseases caused by Yersinia enterocolitica.

Background Improper settings of outdoor smoking points in public places may increase the risk of secondhand smoke exposure among the population. Conducting research on air pollution in and around smoking spots and related influencing factors can provide valuable insights for optimizing the setting of outdoor smoking points. Objective To investigate the influence of the number of smokers at outdoor smoking points and the distance on the diffusion characteristics of surrounding air pollutants, in order to optimize the setting of outdoor smoking points. Methods Surrounding the exhibition halls in the China International Import Expo (CIIE), two outdoor smoking points were randomly selected, one on the first floor (ground level) and the other on the second floor (16 m above ground), respectively. At 0, 3, 6, and 9 m from the smoking points in the same direction, validated portable air pollutant monitors were used to measure the real-time fine particulate matter (PM_2.5) and carbon dioxide (CO₂) concentrations for consecutive 5 d during the exhibition, as well as the environmental meteorological factors at 0 m with weather meters including wind speed, wind direction, and air pressure. An open outdoor atmospheric background sampling point was selected on each of the two floors to carry out parallel sampling. Simultaneously, the number of smokers at each smoking point were double recorded per minute. The relationships between the number of smokers, distance from the smoking points, and ambient PM_2.5 and CO₂ concentrations were evaluated by generalized additive regression models for time-series data after adjustment of confounders such as temperature, relative humidity, and wind speed. Results The median numbers of smokers at smoking points on the first and second floors were 6 [interquartile range (IQR): 3, 9] and 9 (IQR: 6, 13), respectively. Windless (wind speed <0.6 m·s⁻¹) occupied most of the time (85.9%) at both locations. The average concentration of ambient PM_2.5 at the smoking points (0 m) [mean ± standard deviation, (106±114) μg·m⁻³] was 4.2 times higher than that of the atmospheric background [(25±7) μg·m⁻³], the PM_2.5 concentration showed a gradient decline with the increase of distance from the smoking points, and the average PM_2.5 concentration at 9 m points [(35±22) μg·m⁻³] was close to the background level (1.4 times higher). The maximum concentration of CO₂ [(628±23) μmol·mol⁻¹] was observed at 0 m, and its average value was 1.3 times higher than that of the atmospheric background [(481±40) μmol·mol⁻¹], and there was no gradient decrease in CO₂ concentration with increasing distance at 0, 3, 6, and 9 m points. The regression analyses showed that, taking smoking point as the reference, every 3 m increase in distance was associated with a decrease of ambient PM_2.5 by 24.6 [95% confidence interval (95%CI): 23.5, 25.8] μg·m⁻³ (23.2%) and CO₂ by 54.1 (95%CI: 53.1, 55.1) μmol·mol⁻¹ (8.6%). Every one extra smoker at the smoking point was associated with an average increase of PM_2.5 and CO₂ by 2.0 (95%CI: 1.7, 2.8) μg·m⁻³ and 1.0 (95%CI: 0.7，1.2) μmol·mol⁻¹, respectively. The sensitivity analysis indicated that, under windless conditions, the concentrations of PM_2.5 and CO₂ at the smoking points were even higher but the decreasing and dispersion characteristics remained consistent. Conclusion Outdoor smoking points could significantly increase the PM_2.5 concentrations in the surrounding air and the risks of secondhand smoke exposure, despite of the noticeable decreasing trend with increasing distance. Considering the inevitable poor dispersion conditions such as windless and light wind, outdoor smoking points are recommended to be set at least 9 m or farther away from non-smoking areas.

AIM: To explore the risk factors of retinal detachment after stage II vitrectomy in patients with open ocular trauma.METHODS: Retrospective analysis. Totally 278 patients(278 eyes)with open ocular trauma who received stage II vitrectomy in the hospital were included from April 2020 to July 2023. According to the postoperative retinal detachment status, they were divided into detachment group(48 eyes)and non-detachment group(230 eyes). The basic clinical conditions of the two groups of patients were compared, and the factors affecting retinal detachment were analyzed.RESULTS: Univariate analysis revealed that there were statistical differences in wound length, injured area, surgical time after injury, and history of retinal detachment/lesion between the two groups(all P<0.05). Logistics multivariate regression analysis showed that wound length greater than 10 mm, surgical time after injury more than 1 wk, and history of retinal detachment/lesion were risk factors for retinal detachment in patients with open ocular trauma after stage II vitrectomy(all P<0.05).CONCLUSION: The occurrence of retinal detachment in patients with open ocular trauma after stage II vitrectomy is mainly related to the severity of trauma, surgical time after injury and history of ocular retinopathy. It is necessary to perform surgical treatment for patients as soon as possible.
