Background Public places are important areas for daily human activities. Frequent contact with public items promotes their role as vehicles for microbial spread, creating a substantial risk for the transmission of pathogenic microorganisms. Objective To understand the hygiene status and influencing factors of public items in typical public places in Shanghai from 2010 to 2024, and to provide a scientific basis for optimizing the hygiene management of public items. Methods Based on the monitoring data of public items in public places in Shanghai from 2010 to 2024, the hygiene status was evaluated in three stages: 2010–2019, 2020–2022, and 2023–2024. Chi-square test and logistic regression were used to analyze the impact of factors such as monitoring stages, public place types, and public item categories on the hygiene status. Results The public items in

Objective To analyze the case data of farmers' foodborne disease surveillance reports in Guizhou Province from 2022 to 2024, and to provide reference for the precise prevention and control of foodborne diseases among farmers in Guizhou Province. Methods Case data of foodborne disease surveillance reports of farmers were systematically collected from 2022 to 2024 in Guizhou Province. Descriptive epidemiological methods were used to analyze the temporal, geographical, and demographic distribution of foodborne diseases among farmers, along with their primary clinical symptoms and pathogen detection results. Results From 2022 to 2024, a total of 22,882 cases of foodborne diseases were reported among farmers in Guizhou Province. The majority of clinical symptoms (97.81%) were related to the digestive system, with summer being the peak season. While females outnumbered males, the gender difference was statistically insignificant (P >0.05). The 36-55 age group accounted for the highest proportion (38.83%), with Zunyi City (34.89%) and Qiandongnan Prefecture (23.21%) reporting the most cases. Fungal products were the most frequently reported suspected food items (26.96%), and home-made preparation was the primary processing method (58.63%). A total of 1 210 fecal samples were collected through active monitoring with an overall detection rate of 13.22%. Norovirus showed the highest detection rate (9.92%, 120/1 210). Statistically significant differences were observed among different seasons, age groups, regions, types and processing methods of suspected food exposure, and pathogen detection rates (P <0.001). Conclusion Foodborne disease prevention and control among farmers in Guizhou Province should focus on the risks of wild mushroom poisoning in summer and homemade foods, and continuously improve farmers' awareness of the dangers of foodborne diseases and food safety.

ObjectiveTo explore the mechanisms through which Si Junzitang (SJZD) ameliorates Alzheimer's disease (AD) induced by scopolamine (SCOP) in mice and the PC12 cell model induced by H2O2 based on the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway. MethodsIn the animal experiments, an AD model was established in mice by intraperitoneal injection of SCOP (3 mg·kg-1). Morris water maze and open field tests (OFT) were conducted to assess learning and memory abilities. Hematoxylin-eosin (HE) staining and Nissl staining were performed to observe pathological changes in neurons. Immunofluorescence was used to detect amyloid β-protein1-42 (Aβ1-42) expression, and immunohistochemistry was employed to detect phosphorylated (p)-Tau expression. Transmission electron microscopy (TEM) was employed to observe ultrastructural changes in hippocampal neurons and synapses. Biochemical methods were used to measure the levels of acetylcholine (ACh), acetylcholinesterase (AChE), superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), and lactate dehydrogenase (LDH). Real-time PCR and Western blot were employed to measure the mRNA and protein levels of molecules in the Keap1/Nrf2/HO-1 pathway in the hippocampus. In the cell experiments, a PC12 cell model of oxidative damage model was established with H2O2. Cell count kit-8 (CCK-8) assays and flow cytometry were adopted to measure cell viability and apoptosis rates, and Western blot was employed to quantify the expression levels of proteins in the Keap1/Nrf2/HO-1 pathway. ResultsThe animal experiments showed that compared with the model group, the SJZD and donepezil groups showed shortened escape latency (P<0.01), increased time in the target quadrant and platform crossings, and increased movement distance and duration in the central area of the open field (P<0.05, P<0.01). HE and Nissl staining showed more organized neurons and increased Nissl bodies in the drug intervention groups (P<0.05, P<0.01), and the Aβ1-42 and p-Tau expression levels were downregulated (P<0.05, P<0.01). TEM revealed reduced ultrastructural damage in hippocampal neurons and synapses in the drug intervention groups. In addition, the drug intervention groups showed declined levels of MDA, LDH, and AChE (P<0.05, P<0.01), elevated levels of SOD, CAT, and ACh (P<0.05, P<0.01), reduced Keap1 expression and increased Nrf2, HO-1, and NQO1 expression in the hippocampus (P<0.05, P<0.01). The cell experiments showed that compared with the model group, the SJZD-containing serum increased the cell viability (P<0.05, P<0.01), and decreased total apoptosis rates (P<0.05, P<0.01). The drug intervention groups showed upregulated protein levels of Nrf2 and HO-1 and downregulated protein level of Keap1 (P<0.05, P<0.01). ConclusionSJZD demonstrates protective effects against SCOP-induced AD in mice and H2O2-induced damage in PC12 cells through antioxidant mechanisms mediated by the Keap1/Nrf2/HO-1 pathway.

Objective:To investigate the impact of lesions in different nuclei of the subcortical basal ganglia on speech processing functions in patients with post-stroke dysarthria.Methods:From July 2022 to September 2023, a total of 20 patients with post-stroke dysarthria (patient group) and 22 healthy individuals (control group) were recruited. Brain imaging data, including structural magnetic resonance imaging(MRI) and diffusion-weighted imaging (DWI), as well as behavioral data of speech fluency task and picture association task were collected. Structural MRI data was analyzed using SPM12 software to perform voxel-based morphometry (VBM), measuring cortical thickness and gray matter volume (VGM) in specific nuclei of the basal ganglia. Behavioral metrics, such as reaction time (RT) and the number of valid responses were extracted for each task. Statistical analysis was conducted using SPSS 27.0 and R 4.0 softwares. Spearman correlation analysis was applied to examine relationships between neuroimaging parameters and behavioral performance indicators.Results:The patient group exhibited significantly smaller gray matter volumes in both left and right caudate nuclei((2.69±0.92)mm 3, (3.17±0.91)mm 3 ) and putamen (3.31±1.08)mm 3, (3.66±0.91)mm 3) compared to the control group (caudate nuclei (3.19±0.36)mm 3, (3.49±0.52)mm 3 putamen (4.52±0.54)mm 3, (4.72±0.64)mm 3), with statistically significant differences ( t=-2.83, 1.68; t=-3.59, 3.52, both P<0.05). Behavioral experiments revealed that the patient group exhibited significantly prolonged reaction time during picture association and naming tasks (1 910.50(1 214.25, 3 806.75) ms, 1 362.00(978.00, 2 297.00) ms) compared to the control group (1 618.00(1 162.75, 2 401.75) ms, 1 224.00(984.25, 1 661.50) ms; Z=-5.20, -4.61, both P<0.05). Gray matter volumes in the left caudate nucleus and left putamen exhibited negative correlations with reaction times during the picture naming task ( r=-0.52, -0.54, both P<0.05). Additionally, the gray matter volume of the left putamen demonstrated a positive correlation with the number of valid responses in speech fluency task-T2 ( r=0.46, P<0.05), whereas the left globus pallidus volume showed a negative correlation with speech fluency task-T1 ( r=-0.51, P<0.05) with the same measure. Conclusion:Lesions in the left subnuclei of the basal ganglia directly impair early-stage speech functions, including conceptual preparation and lexical selection, whereas right-side lesions exert less pronounced effects on linguistic performance compared to their left counterparts. Furthermore, the basal ganglia's involvement in higher-order linguistic processing may represent an indirect consequence of cognitive decline.

Ferroptosis is an emerging form of regulated cell death characterized by iron-dependent lipid peroxidation and the failure of the antioxidant system,which results in iron-dependent oxidative damage to the cell membrane. Ferroptosis is implicated in various biological processes,including cell proliferation,aging,and differentiation. The regulation of oxidative stress by ferroptosis is closely associated with the inactivation of glutathione peroxidase 4(Gpx4),dysfunction of the cysteine/glutamate antiporter System Xc-,the production of reactive oxygen species derived from oxidized polyunsaturated fatty acids,and alterations in lipid metabolism. Oxidative stress is a critical mechanism underlying the onset and progression of benign prostatic hyperplasia(BPH)and plays a pivotal role in its pathogenesis. Ferroptosis may regulate the occurrence and development of BPH by mediating lipid oxidative stress response.
