Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.

Clathrin-mediated endocytosis (CME) is a critical process by which cells internalize macromolecular substances and initiate vesicle trafficking, serving as the foundation for many cellular activities. Central to this process are clathrin-coated structures (CCSs), which consist of clathrin-coated pits (CCPs) and clathrin plaques. While clathrin-coated pits are well-established in the study of endocytosis, clathrin plaques represent a more recently discovered but equally important component of this system. These plaques are large, flat, and extended clathrin-coated assemblies found on the cytoplasmic membrane. They are distinct from the more typical clathrin-coated pits in terms of their morphology, larger surface area, and longer lifespan. Recent research has revealed that clathrin plaques play roles that go far beyond endocytosis, contributing to diverse cellular processes such as cellular adhesion, mechanosensing, migration, and pathogen invasion. Unlike traditional clathrin-coated pits, which are transient and dynamic structures involved primarily in the internalization of molecules, clathrin plaques are more stable and extensive, often persisting for extended periods. Their extended lifespan suggests that they serve functions beyond the typical endocytic role, making them integral to various cellular processes. For instance, clathrin plaques are involved in the regulation of intercellular adhesion, allowing cells to better adhere to one another or to the extracellular matrix, which is crucial for tissue formation and maintenance. Furthermore, clathrin plaques act as mechanosensitive hubs, enabling the cell to sense and respond to mechanical stress, a feature that is essential for processes like migration, tissue remodeling, and even cancer progression. Recent discoveries have also highlighted the role of clathrin plaques in cellular signaling. These plaques can serve as scaffolds for signaling molecules, orchestrating the activation of various pathways that govern cellular behavior. For example, the recruitment of actin-binding proteins such as F-actin and vinculin to clathrin plaques can influence cytoskeletal dynamics, helping cells adapt to mechanical changes in their environment. This recruitment also plays a pivotal role in regulating cellular migration, which is crucial for developmental processes. Additionally, clathrin plaques influence receptor-mediated signal transduction by acting as platforms for the assembly of signaling complexes, thereby affecting processes such as growth factor signaling and cellular responses to extracellular stimuli. Despite the growing body of evidence that supports the involvement of clathrin plaques in a wide array of cellular functions, much remains unknown about the precise molecular mechanisms that govern their formation, maintenance, and turnover. For example, the factors that regulate the recruitment of clathrin and other coat proteins to form plaques, as well as the signaling molecules that coordinate plaque dynamics, remain areas of active research. Furthermore, the complex interplay between clathrin plaques and other cellular systems, such as the actin cytoskeleton and integrin-based adhesion complexes, needs further exploration. Studies have shown that clathrin plaques can respond to mechanical forces, with recent findings indicating that they act as mechanosensitive structures that help the cell adapt to changing mechanical environments. This ability underscores the multifunctional nature of clathrin plaques, which, in addition to their role in endocytosis, are involved in cellular processes such as mechanotransduction and adhesion signaling. In summary, clathrin plaques represent a dynamic and versatile component of clathrin-mediated endocytosis. They play an integral role not only in the internalization of macromolecular cargo but also in regulating cellular adhesion, migration, and signal transduction. While much has been learned about their structural and functional properties, significant questions remain regarding the molecular mechanisms that regulate their formation and their broader role in cellular physiology. This review highlights the evolving understanding of clathrin plaques, emphasizing their importance in both endocytosis and a wide range of other cellular functions. Future research is needed to fully elucidate the mechanisms by which clathrin plaques contribute to cellular processes and to better understand their implications for diseases, including cancer and tissue remodeling. Ultimately, clathrin plaques are emerging as crucial hubs that integrate mechanical, biochemical, and signaling inputs, providing new insights into cellular function and the regulation of complex cellular behaviors.

Objective: To investigate the quality and influencing factors of direct drinking water in schools in Nanjing City, so as to provide basis for management of school drinking water. Methods: From April to July 2023, direct drinking water equipment from 146 primary and secondary schools were selected from Nanjing City using a stratified random sampling method and tested for colony forming units (CFU) and permanganate index. Mann-Whitney U test was used to compare the differences between groups, and multiple linear regression was used to analyze the influencing factors. Results: The CFU and permanganate levels of school direct drinking water in Nanjing City were 1.00(0.00,15.50)CFU/mL and 0.47(0.26, 0.75)mg/L, respectively. The CFU level increased when the filter replacement time exceeded 3 months and when the water source was piped, while the permanganate index increased when the filter replacement time exceeded 3 months and using activated carbon technology ( Z =-2.21, -3.92, -2.31, -8.45 , P <0.05). The results of multiple linear regression analysis showed that the replacement time of filter element exceeding 3 months was positively correlated with the CFU level, and the process type involving activated carbon, a laid pipe network and a filter replacement time exceeding 3 months were positively correlated with the permanganate index( β =167.08, 0.32, 0.35, 0.11, P ＜0.05). Conclusions There are certain problems with the water quality of primary and secondary school direct drinking water in Nanjing City. Schools should promptly replace the filter and maintain the drinking water equipment to ensure the hygiene and safety of campus water quality.

Objective To study the application of CE-Chirp in the evaluation of hearing impairment in forensic medicine by testing the auditory brainstem response(ABR)in adults using CE-Chirp to ana-lyze the relationship between the V-wave response threshold of CE-Chirp ABR test and the pure tone hearing threshold.Methods Subjects(aged 20-77 with a total of 100 ears)who underwent CE-Chirp ABR test in Changzhou De'an Hospital from January 2018 to June 2019 were selected to obtain the V-wave response threshold,and pure tone air conduction hearing threshold tests were conducted at 0.5,1.0,2.0 and 4.0 kHz,respectively,to obtain pure tone listening threshold.The differences and statistical differences between the average pure tone hearing threshold and V-wave response threshold were compared in different hearing levels and different age groups.The correlation,differences and statistical differences between the two tests at each frequency were analyzed for all subjects.The lin-ear regression equation for estimating pure tone hearing threshold for all subjects CE-Chirp ABR V-wave response threshold was established,and the feasibility of the equation was tested.Results There was no statistical significance in the CE-Chirp ABR response threshold and pure tone hearing threshold dif-ference between different hearing level groups and different age groups(P>0.05).There was a good correlation between adult CE-Chirp ABR V-wave response threshold and pure tone hearing threshold with statistical significance(P<0.05),and linear regression analysis showed a significant linear correla-tion between the two(P<0.05).Conclusion The use of CE-Chirp ABR V-wave response threshold can be used to evaluate subjects'pure tone hearing threshold under certain conditions,and can be used as an audiological test method for forensic hearing impairment assessment.

Background Drinking water contains a variety of chemicals that may pose certain health risks to the human body. Objective To evaluate carcinogenic and non-carcinogenic health risks of chemical pollutants in drinking water in Nanjing from 2014 to 2022. Methods According to the Standard examination methods for drinking water (GB/T 5750-2006) and the Standards for drinking water quality (GB 5749-2006), the conventional water quality indexes of finished water, tap water, and secondary water supply in Nanjing from 2014 to 2022 were monitored. The health risk assessment model recommended by the United States Environmental Protection Agency (US EPA) was used to assess the health risks of 16 chemicals [arsenic, cadmium, chromium (hexavalent), lead, mercury, selenium, cyanide, fluoride, nitrate nitrogen, trichloromethane, carbon tetrachloride, aluminum, iron, manganese, copper, and zinc] in drinking water through different routes (drinking water and skin contact) in different populations (adult males, adult females, and children). Region (urban and rural), water period (dry period and wet period), and water sample type (finished water, tap water, and secondary water supply) were stratified for analysis. Results From 2014 to 2022, a total of 4198 samples of drinking water were monitored in Nanjing, including 483 samples of finished water, 3313 samples of tap water, and 402 samples of secondary water supply. The pass rates of all indicators were above 99%. The health risk assessment results showed that the carcinogenic/non-carcinogenic risks of arsenic and lead presenting a trend of first increasing from 2015 and 2016 respectively, remaining relatively high for 3 and 4 consecutive years respectively, and then decreasing from 2018 and 2020 respectively before remaining stable; the carcinogenic risk of cadmium was much higher than that of other chemicals, and the risk was greater than 1.00×10⁻⁴ except for 2018 and 2019. The non-carcinogenic risks of drinking water in different populations (adult males, adult females, and children) under different exposure modes (intake of drinking water and skin contact) were less than 1. The values of carcinogenic risk via drinking water in total population and of cadmium intake via drinking water in all sub-groups (adult males, adult females, and children) were greater than 1.00×10⁻⁴. The carcinogenic/non-carcinogenic risk of drinking water was the highest in children, and the carcinogenic/non-carcinogenic risk via drinking water ingestion was higher than that via skin contact. The stratified analysis showed that the carcinogenic/non-carcinogenic risks of arsenic and cadmium in urban drinking water were higher than those in rural drinking water (P<0.05); the carcinogenic/non-carcinogenic risks of arsenic and trichloromethane in wet season were higher than those in dry season (P<0.05); the carcinogenic risks of cadmium in different types of water were all greater than 1.00×10⁻⁴; the health risks varied by chemicals and water sample types for the other chemicals, but all were within an acceptable level. Conclusion The non-carcinogenic risks and carcinogenic risks of selected chemical pollutants in drinking water in Nanjing City from 2014 to 2022 show decreasing or stable trends. Among the 16 chemicals, the carcinogenic risk of cadmium exceeds the acceptable range recommended by the US EPA, and the carcinogenic/non-carcinogenic risks of the remaining chemicals are within the acceptable ranges. Cadmium should be given priority attention in future risk management of drinking water.
