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 13807 public places were monitored. A total of 1 022 bed sheets and 9 271 towels were tested for pH value, with qualified rates of 77.66% and 87.81%, respectively. The OR (95%CI) for the pH compliance of towels relative to bed sheets was 1.77 (1.45, 2.15). Compared with bathing places, the ORs for pH compliance of towels in hair salons and beauty salons were 2.24 (1.75, 2.87) and 2.15 (1.57, 2.95), respectively. Additionally, a total of 221 650 samples from various public items were tested for microorganisms, yielding 215554 qualified samples, with an average qualified rate of 97.25%. The qualified rates for total bacterial count, total fungal count, coliforms, and Staphylococcus aureus were 92.66%, 94.63%, 98.85%, and 99.84%, respectively. The logistic regression analysis showed that, compared to the 2016–2019 baseline, no statistically significant differences were observed in the qualified rates of total fungal count across different stages; however, significantly higher qualified rates for total bacterial count, total fungal count, coliforms, and Staphylococcus aureus were recorded during 2020–2022, with ORs (95%CI) of 1.27 (1.16, 1.38), 23.20 (8.42, 63.94), and 12.08 (1.63, 89.92), respectively. Conclusion The pH compliance ranks among the top tier nationwide for cotton textile goods in Shanghai, suggesting minimal detergent retention. Furthermore, continuous improvement in cleaning and disinfection measurements has markedly enhanced the microbial hygiene of public items in public places.

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-protein_1-42 （Aβ_1-42） 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 Aβ_1-42 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 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.

Objective To compare the efficacy of stenting in the treatment of idiopathic intracranial hypertension(IIH)complicated by different types of venous sinus stenosis(VSS).Methods The clinical data of 48 patients with IIH complicated by VSS,who received stenting therapy at the First Affiliated Hospital of Zhengzhou University of China from January 2019 to September 2023,were retrospectively analyzed.According to the type of VSS,the patients were divided into intrinsic stenosis group(n=20)and the extrinsic stenosis group(n=28).The improvement of symptoms,Frisén grade of papilledema,lumbar puncture opening pressure(LPOP),trans-stenosis pressure gradient(△P)of VSS,and surgery-related complications were compared between the two groups.Results The mean age of the patients in the intrinsic stenosis group was greater than that of the patients in the extrinsic stenosis group(41.60 years vs.35.25 years,P=0.049).The length of the narrowed segment in the extrinsic stenosis group was 22.5 mm,which was significantly longer than 19.0 mm in the intrinsic stenosis group(P=0.007).The postoperative Frisén grade of papilledema in the extrinsic stenosis group was obviously lower than that in the intrinsic stenosis group(P=0.037).No statistically significant differences in the other clinical data existed between the two groups(all P＞0.05).After stenting,all of the median △P,mean LPOP,and median Frisén grade of papilledema were decreased significantly when compared with their preoperative values(all P＜0.001),and the postoperative 3-day median Frisén grade of papilledema in the extrinsic stenosis group was much lower(P=0.037).The patients were followed up for one year,the clinical symptoms of the patients in both groups were improved to varying degrees.At the time of discharge,the proportion of patients having no symptoms of papilledema in the extrinsic stenosis group was 57.1％,which was higher than 22.2％in the intrinsic stenosis group(P=0.049),and no statistically significant differences in the improvements of other symptoms existed between the two groups(all P＞0.05).There was no significant difference in the incidence of complications between the two groups(P=0.563).Conclusion Venous sinus stenting can effectively treat patients with IIH complicated by different types of VSS.

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.

Objective To investigate the effect of mulberry anthocyanin on the morphology and func-tion of vascular endothelial cells(VEC)and its possible mechanism at the level of autophagy.Methods VEC were cultured in vitro and divided into 5.5/0 mmol/L control group,11/0.125,22/0.250,33/0.500,44/1.000,55/2.000 mmol/L high glucose/high fat groups.The cell functional levels and autophage levels in each group were detected.The optimal high glucose/high lipid concentration was selected as the VEC function inju-ry model group.10,25,50 μmol/L mulberry anthocyanins were added into the model group for processing and divided into the low,middle and high concentrations of mulberry anthocyanin groups.The effects of mulberry anthocyanin on the morphology,function and autophagy of VEC in high sugar and high fat stress were ob-served.Then the autophagy regulator(rapamycin)was added to study its action mechanism.HE staining was used to observe the number and morphology of cells,the CCK-8 assay was used to detect the viability of VEC,the flow cytometry was used to detect the level of reactive oxygen species(ROS)in VEC,the Western blot was used to detect the expression level of Beclin-1 and p62 proteins in VEC,and the kit method was used to detect the level of nitric oxide(NO)and endothelin-1(ET-1)in VEC.Results Compared with the control group,the number and morphology of cells in the middle and high concentrations of high glucose/high fat groups were changed,the cell viability,p62,NO levels were significantly decreased(P<0.05),while the ROS,ET-1,and Beclin-1 expression levels were increased significantly(P<0.05).Compared with the model group,the number of cells in the mulberry anthocyanin groups was increased,morphology was improved,the cellular viability,p62 and No levels were significantly increased,and ROS,Beclin-1 and ET-1 levels were significantly decreased(P<0.05).Compared with the high concentration mulberry anthocyanin group,the cells number was decreased af-ter adding rapamycin,the morphology changed to be irregular,the NO level was decreased,and the ET level was increased(P<0.05).Compared with the control group,the p-phosphatidylinositol 3-kinase(PI3K)and p-protein kinase B(Akt)relative expression levels in the model group were significantly decreased(P<0.05);compared with the model group,the p-PI3K and p-Akt relative expression levels in the high concentration mulberry anthocyanin group were significantly increased(P<0.05).Conclusion Mulberry anthocyanin could in-hibit autophagy by activating the PI3K/Akt/mammalian target of rapamycin(mTOR)signaling pathway and improve the morphology and function of VEC under high glucose and lipid stress.

OBJECTIVE: This study investigates the efficacy and mechanisms of Qingjie Fuzheng Granules (QFG) in inhibiting colitis-associated colorectal cancer (CAC) development via RNA sequencing (RNA-seq) and 16S ribosomal RNA (rRNA) correlation analysis. METHODS: CAC was induced in BALB/c mice using azoxymethane (AOM) and dextran sulfate sodium (DSS), and QFG was administered orally to the treatment group. The effects of QFG on CAC were evaluated using disease index, histology, and serum T-cell ratios. RNA-seq and 16S rRNA analysis assessed the transcriptome and microbiome change. Key pharmacodynamic pathways were identified by integrating these data and confirmed via Western blotting and immunofluorescence. The link between microbiota and CAC-related markers was explored using linear discriminant analysis effect size and Spearman correlation analysis. RESULTS: Long-term treatment with QFG prevented AOM/DSS-induced CAC formation, reduced levels of interleukin (IL)-1β, tumor necrosis factor-alpha (TNF-α), IL-6, and interferon γ (IFN-γ), and increased CD3⁺ and CD4⁺/CD8⁺ T cells ratio, without causing hepatic or renal toxicity. A 16S rRNA analysis revealed that QFG rebalanced the Firmicutes/Bacteroidetes ratio and mitigated AOM/DSS-induced microbiota disturbances. Transcriptomics and Western blotting analysis identified the nucleotide-binding oligomerization domain-containing protein 2 (NOD2)/nuclear factor kappa-B (NF-κB) pathway as key for QFG's treatment against CAC. Furthermore, QFG decreased the abundance of Bacilli, Bacillales, Staphylococcaceae, Staphylococcus, Lactobacillales, Aerococcus, Alloprevotella, and Akkermansia, while increasing Clostridiales, Lachnospiraceae, Lachnospiraceae_NK4A136_group, Ruminococcaceae, and Muribaculaceae, which were highly correlated with CAC-related markers or NOD2/NF-κB pathway. CONCLUSION By mapping the relationships between CAC, immune responses, microbiota, and key pathways, this study clarifies the mechanism of QFG in inhibiting CAC, highlighting its potential for clinical use as preventive therapy.

OBJECTIVE T o explore the action mechanisms of Ganghuo Qingwen granules(GHQWG)in treatment of influenza based on network pharmacology and molecular docking technique.METHODS The TCMSP database was logged in to search for active compounds,targets of GHQWG and targets of influenza so as to screen out the intersected targets between HGQWG and influenza and establish a drug-ingredient-target network.The poten-tial mechanisms were analyzed by means of protein-protein interaction analysis,Gene Ontology(GO)function an-notation and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment,and the activity of binding the key targets with ingredients was validated by molecular docking.RESULTS GHQWG contained 90 types of po-tential active ingredients,312 active ingredient targets,1996 influenza targets and 134 intersection targets.The core ingredients included quercetin,kaempferol and luteolin;the key targets involved V-Rel reticuloendotheliosis viral oncogene homolog A(RELA),tumor protein 53(TP53),mitogen-activated protein kinase 3(MAPK3),tumor necrosis factor(TNF),serine/threonine kinase proteins 1(AKT1)and mitogen-activated protein kinase 1(MAPK1).The function enrichment showed that GHQWG could regulate the processes of gene expression,in-flammatory reaction and apoptosis.The result of KEGG indicated that GHQWG played therapeutic effect on influ-enza mainly through C type agglutinin receptor,TNF and in terleukin-17(IL-17)signaling pathway.The molecu-lar docking analysis showed that RELA,TP53,M APK3,TNF,AKT1 and M APK1 had strong activities of bind-ing with quercetin,kaempferol,luteolin,β-sitosterol,wogonin,stigmasterol,caffeic acid and isorhamnetin.CONCLUSION GHQWG may regulate the key targets of signaling pathways of C type agglutinin receptor,TNF and IL-17 through multiple ingredients-multiple targes-multiple pathway mechanisms so as to play the therapeutic effect on influenza.

Influenza(flu)is an acute respiratory infection caused by influenza viruses,characterized by high morbidity,strong trans-mission and general susceptibility of the population,and often accompanied by clinical symptoms such as fever,cough and muscle aches,etc.With the global pandemic of influenza,it has become a major challenge in the field of global public health,and therefore,it is particularly important to explore effective treatment methods.Chinese medicine has thousands of years of experience in treating in-fectious diseases and plays an important role in the prevention and treatment of influenza.This paper provides a comprehensive and systematic review of the Chinese medicine name,etiology,identification and typing,treatment methods and mechanism of action of in-fluenza,aiming to make up for the lack of the current summary of Chinese medicine treatment of influenza,with a view to providing cer-tain ideas and theoretical basis for the study of Chinese medicine treatment of influenza.

Sepsis is a systemic inflammatory response triggered by infection and often leads to acute kidney injury(AKI).The pathogenesis of sepsis-associated AKI is complex,involving multiple factors such as renal ischemia,inflammation and oxidative stress.In recent years,pyroptosis,a pro-inflammatory form of programmed cell death,has gradually attracted the attention of researchers.Pyroptosis is activated by inflammasomes(e.g.,the NOD-like receptor pyrin domain-related protein 3 inflammasome,NLRP3 inflammasome),accompanied by Gas-dermin D(GSDMD)-mediated formation of cell membrane pores and release of cellular contents,which leads to exacerbation of local and systemic inflammatory responses.The mechanism of pyroptosis in sepsis-associated AKI has not been fully elucidated,but AKI is directly involved in the process of renal functional impairment by indu-cing the death of renal tubular epithelial cells and exacerbating the local inflammatory response.Blockade of key molecules in the pyroptosis pathway,such as GSDMD or NLRP3 inflammasome,can significantly alleviate renal injury,suggesting that the pyroptosis pathway may be a potential therapeutic target for sepsis-associated AKI.This review summarizes the recent research progress on pyroptosis in sepsis-associated AKI,and discuss its cen-tral role in the pathogenesis,particularly focusing on the inflammasome and GSDMD pathways.Additionally,this paper analyzes the potential of focal death inhibition as a therapeutic strategy and proposes future research direc-tions with the expectation of providing references for the treatment of sepsis-related AKI.
