ObjectiveTo investigate the therapeutic effects of the Anemarrhenae Rhizoma water extract （AR） on Alzheimer's disease （AD） model rats and to explore its potential underlying mechanisms. MethodsMale rats were intraperitoneally injected with D-galactose （100 mg·kg^-1） for 42 days， and on day 14， 1 μL of β-amyloid （Aβ_25-35， 2 g·L^-1） solution was injected into the hippocampus. Rats were randomly divided into a model group， low-dose AR （0.6 g·kg^-1）， medium-dose AR （1.2 g·kg^-1）， high-dose AR （2.4 g·kg^-1）， and a positive control group （donepezil， 5 mg·kg^-1）. Healthy rats receiving only a hippocampal injection of 1 μL of sterile saline served as the sham-operated group. From day 21， rats in the treatment groups were administered the corresponding drugs by gavage once daily for 21 consecutive days， while the blank control and model groups received an equal volume of saline. Learning and memory abilities were assessed using the Morris water maze. Brain tissue damage was observed by hematoxylin and eosin （HE） staining， and neuronal apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick-end labeling （TUNEL） staining. Levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10） in brain tissues were measured by enzyme-linked immunosorbent assay （ELISA）. BV2 microglial cells were co-cultured with Aβ_25-35 （40 μmol·L^-1） for 2 h， and cell viability was determined by the CCK-8 assay to screen the optimal concentration of AR-containing serum （S-AR）. Cells were divided into blank control， Aβ_25-35， S-AR， EX527 ［silent information regulator 1 （SIRT1） inhibitor］， and S-AR+EX527 groups. Immunofluorescence staining was used to detect the expression of CD16， CD206， and high-mobility group box 1 （HMGB1）. Western blot analysis was performed to measure the protein expression of CD16， inducible nitric oxide synthase （iNOS）， CD206， arginase （Arg）， and proteins related to the SIRT1/HMGB1/nuclear factor-κB （NF-κB） signaling pathway. ResultsIn vivo experiments showed that， compared with the sham-operated group， the model group exhibited reduced platform crossings and time spent in the target quadrant （P<0.01）， prolonged escape latency， increased hippocampal neuronal apoptosis （P<0.01）， and obvious hippocampal damage. The expression levels of IL-6， TNF-α， IL-10， CD16， and iNOS in brain tissues were significantly elevated （P<0.01）， while CD206 and Arg protein expression showed an increasing trend without statistical significance. Compared with the model group， all AR-treated groups significantly increased platform crossings and target quadrant time （P<0.05， P<0.01）， alleviated hippocampal damage， reduced escape latency and neuronal apoptosis， downregulated the expression of TNF-α， IL-6， CD16， and iNOS （P<0.05， P<0.01）， and upregulated the expression of IL-10， CD206 and Arg （P<0.05， P<0.01）. In vitro experiments demonstrated that， compared with the blank control group， the Aβ_25-35 group showed increased fluorescence intensity of CD206， CD16， and HMGB1， as well as elevated protein expression of iNOS and CD16 （P<0.01）， while CD206 and Arg protein expression exhibited an increasing trend without statistical significance. After S-AR intervention， CD206 fluorescence intensity and the protein expression of Arg and CD206 were significantly increased （P<0.01）， whereas the fluorescence intensity of CD16 and HMGB1 and the protein expression of iNOS and CD16 were significantly decreased （P<0.01）. These effects were reversed by EX527 （P<0.05， P<0.01）. Furthermore， compared with the blank control group， the Aβ_25-35 group showed significantly increased cytoplasmic HMGB1 expression and p-p65/p65 ratio （P<0.01）， along with significantly decreased SIRT1 and nuclear HMGB1 expression （P<0.01）. In contrast， the S-AR group exhibited opposite trends compared with the Aβ_25-35 group， and the regulatory effects of S-AR on these proteins were reversed by EX527 （P<0.01）. ConclusionAR exerts neuroprotective effects in AD model rats by regulating microglial polarization and alleviating neuroinflammation， potentially through modulation of the SIRT1/HMGB1/NF-κB signaling pathway.

Objective To identify core targets of hepatocellular carcinoma (HCC) by using bioinformatics and specific algorithms, explore their relationships with immune cells, and investigate the causal relationships between immune cells and HCC through Mendelian randomization. Methods Relevant genes associated with the development of HCC were screened using the GEO and TCGA databases. Immune infiltration analysis was conducted using GSVA and CIBERSORT algorithms. A bidirectional Mendelian randomization analysis was then performed to explore the causal relationships between immune cells and HCC. Results A total of 284 HCC-related genes were identified, with 120 genes recognized within the protein interaction network. Immune infiltration analysis revealed significant correlations between key genes and immune cells. Mendelian randomization results indicated that HLA DR on CD33⁺ HLA DR⁺ CD14dim (OR=1.097, 95%CI: 1.002–1.201, P=0.045, P_Bonferroni=0.091) and CD8 on CD28⁺ CD45RA⁺ CD8⁺ T cell (OR=1.123, 95%CI: 1.027–1.228, P=0.011, P_Bonferroni=0.022) were the risk factors for HCC. Conversely, HLA DR⁺⁺ monocyte absolute count was identified as a protective factor for HCC (OR=0.812, 95%CI: 0.702–0.938, P=0.005, P_Bonferroni=0.139). Conclusion The occurrence and development of liver cancer may be related to CDK1, CCNB1, and CDC20, showing a high degree of correlation with Th2 cells, T helper cells, Th17 cells, and DCs. Mendelian randomization shows that HLA DR on CD33⁺HLA DR⁺ CD14dim and CD8 on CD28⁺CD45RA⁺CD8⁺T cells are associated with an increased risk of HCC. The risk of hepatocellular carcinoma is associated with a decrease in the level of HLA DR⁺⁺monocyte absolute count.

Objective To investigate the industrial and job changes among fishermen and their impact on economic incomes and schistosomiasis control following fishing ban and withdrawal in Poyang Lake areas, so as to provide insights into formulation of the schistosomiasis control strategy in these areas. Methods One township was selected as the study area from each of Duchang County, Poyang County and Yugan County around the Poyang Lake areas from May to June, 2023, and at least 500 fishermen at ages of 60 years and less were sampled from each township. Questionnaires were allocated to all subjects via the “Questionnaire Star” platform, including demographics, ratio of profits from different production activities before and after fishing ban and withdrawal, contact with infested water before and after fishing ban and withdrawal, and changes in household economic income before and after fishing ban and withdrawal. Subjects’ schistosomiasis examination and treatment data, and development of schistosomiasis hepatic fibrosis and advanced schistosomiasis were collected from 2016 to 2023. The changes in economic incomes, contact with infested water, sero-prevalence of human schistosomiasis, and proportions of schistosomiasis examinations and treatments were compared among study subjects. Results A total of 2 449 fishermen with an average age of (49.55 ± 8.86) years were investigated, including 1 654 full-time fishermen (67.54%) and 795 part-time fishermen (32.46%). The ratios of profits from fishing activities reduced from 88.15% and 34.82% before fishing ban and withdrawal to < 0.01% and 0.03% after fishing ban and withdrawal among full-time and part-time fishermen, while the ratios of profits from other production activities increased. The proportion of full-time fishermen who thought a reduction or a large reduction in their economic incomes was 79.93% (1 322/1 654), which was higher than that (66.79%, 531/795) of part-time fishermen (χ² = 50. 307, P < 0.001), and the proportion of part-time fishermen who thought minor changes in their economic incomes was 15.60% (124/795), which was higher than that (4.11%, 68/1 654) of full-time fishermen (χ² = 96.274, P < 0.001). There was a reduction in the contact with infested water among fishermen following fishing ban and withdrawal, and the proportions of respondents that had no contact, a large reduction in contact and a reduction in contact with infested water were 14.74% (361/2 449), 57.78% (1 415/2 449) and 26.05% (638/2 449), respectively. In addition, the sero-prevalence of schistosomiasis, and proportions of schistosomiasis examinations and treatments decreased from 9.79%, 87.14%, and 97.80% in 2016 to 4.38%, 53.16%, and 71. 51% in 2023 among fishermen in Duchang County, Poyang County and Yugan County (χ² = 6.944, 865.194, 238.953, all P values < 0.01), and the prevalence of schistosomiasis liver fibrosis and advanced schistosomiasis was 42.64% (826/1 937) and 6.08% (149/2 449) among study subjects, respectively. Conclusions Industrial and job changes among fishermen are beneficial for schistosomiasis control after fishing ban and withdrawal in Poyang Lake areas; however, there is an increased difficulty for management of fishermen due to an increase in number of migrant labors and other factors.

Blue light inactivation technology, particularly at the 405 nm wavelength, has demonstrated distinct and multifaceted mechanisms of action against both Gram-positive and Gram-negative bacteria, offering a promising alternative to conventional antibiotic therapies. For Gram-positive pathogens such as Bacillus cereus, Listeria monocytogenes, and methicillin-resistant Staphylococcus aureus (MRSA), the bactericidal effects are primarily mediated by endogenous porphyrins (e.g., protoporphyrin III, coproporphyrin III, and uroporphyrin III), which exhibit strong absorption peaks between 400-430 nm. Upon irradiation, these porphyrins are photoexcited to generate cytotoxic reactive oxygen species (ROS), including singlet oxygen, hydroxyl radicals, and superoxide anions, which collectively induce oxidative damage to cellular components. Early studies by Endarko et al. revealed that (405±5) nm blue light at 185 J/cm² effectively inactivated L. monocytogenes without exogenous photosensitizers, supporting the hypothesis of intrinsic photosensitizer involvement. Subsequent work by Masson-Meyers et al. demonstrated that 405 nm light at 121 J/cm² suppressed MRSA growth by activating endogenous porphyrins, leading to ROS accumulation. Kim et al. further elucidated that ROS generated under 405 nm irradiation directly interact with unsaturated fatty acids in bacterial membranes, initiating lipid peroxidation. This process disrupts membrane fluidity, compromises structural integrity, and impairs membrane-bound proteins, ultimately causing cell death. In contrast, Gram-negative bacteria such as Salmonella, Escherichia coli, Helicobacter pylori, Pseudomonas aeruginosa, and Acinetobacter baumannii exhibit more complex inactivation pathways. While endogenous porphyrins remain central to ROS generation, studies reveal additional photodynamic contributors, including flavins (e.g., riboflavin) and bacterial pigments. For instance, H. pylori naturally accumulates protoporphyrin and coproporphyrin mixtures, enabling efficient 405 nm light-mediated inactivation without antibiotic resistance concerns. Kim et al. demonstrated that 405 nm light at 288 J/cm² inactivates Salmonella by inducing genomic DNA oxidation (e.g., 8-hydroxy-deoxyguanosine formation) and disrupting membrane functions, particularly efflux pumps and glucose uptake systems. Huang et al. highlighted the enhanced efficacy of pulsed 405 nm light over continuous irradiation for E. coli, attributing this to increased membrane damage and optimized ROS generation through frequency-dependent photodynamic effects. Environmental factors such as temperature, pH, and osmotic stress further modulate susceptibility, sublethal stress conditions (e.g., high salinity or acidic environments) weaken bacterial membranes, rendering cells more vulnerable to subsequent ROS-mediated damage. The 405 nm blue light inactivates drug-resistant Pseudomonas aeruginosa through endogenous porphyrins, pyocyanin, and pyoverdine, with the inactivation efficacy influenced by bacterial growth phase and culture medium composition. Intriguingly, repeated 405 nm exposure (20 cycles) failed to induce resistance in A. baumannii, with transient tolerance linked to transient overexpression of antioxidant enzymes (e.g., superoxide dismutase) or stress-response genes (e.g., oxyR). For Gram-positive bacteria, porphyrin abundance dictates sensitivity, whereas in Gram-negative species, membrane architecture and accessory pigments modulate outcomes. Critically, ROS-mediated damage is nonspecific, targeting DNA, proteins, and lipids simultaneously, thereby minimizing resistance evolution. The 405 nm blue light technology, as a non-chemical sterilization method, shows promise in medical and food industries. It enhances infection control through photodynamic therapy and disinfection, synergizing with red light for anti-inflammatory treatments (e.g., acne). In food processing, it effectively inactivates pathogens (e.g., E. coli, S. aureus) without altering food quality. Despite efficacy against multidrug-resistant A. baumannii, challenges include device standardization, limited penetration in complex materials, and optimization of photosensitizers/light parameters. Interdisciplinary research is needed to address these limitations and scale applications in healthcare, food safety, and environmental decontamination.
