AIM: To compare the effectiveness of foldable capsular body(FCB)with traditional scleral buckling(SB)in the treatment of experimental retinal detachment animal models.METHODS: After successfully establishing rhegmatogenous retinal detachment(RRD)animal models, 24 New Zealand white rabbits were randomly divided into three groups(RRD models group, SB group, and FCB group), with 8 rabbits in each group. The FCB and SB groups underwent SB and FCB surgeries for the RRD animal models, while the RRD models group only consists of RRD models without any surgical intervention during the follow-up period. The follow-up duration was 3 mo. Wide-field neonatal fundus imaging system and ophthalmic B-ultrasound were used to assess the fundus conditions before and after surgery. The Icare® TONOVET Plus tonometer was utilized to evaluate intraocular pressure changes before and after surgery. The Eaton and Draize scoring systems were selected to monitor postoperative inflammatory reactions.RESULTS: The retinal reattachment rates in the FCB and SB groups were 87.5% and 75.0%, respectively, with no statistically significant difference between the groups(P>0.05). The intraocular pressure in both the FCB and SB groups increased postoperatively compared to preoperative levels(P<0.01), and there were no significant differences in intraocular pressure at any time points during the follow-up period between the groups(P>0.05). The intraocular pressure in the RRD models group remained at a low level throughout the follow-up period. The average surgical time for the FCB group was 16.87±2.29 min, which was shorter than 46.25±4.74 min in the SB group(t=-15.166, P<0.001). According to the Eaton and Draize scoring systems, the FCB group had lower grades of conjunctival hyperemia and edema in the early postoperative period compared to the SB group, indicating milder inflammatory reactions(P<0.05).CONCLUSION: Both FCB and SB are effective in treating experimental RRD. Compared to SB, FCB is simpler to operate, and also has a shorter surgical time and milder postoperative inflammatory reactions.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

Objective To explore the promoting effect of long-term administration of nicotiflorin on the recovery of neurological function in rats with cerebral ischemia-reperfusion injury （CIRI）. Methods The CIRI model was established and nicotiflorin was injected intraperitoneally after 1 hour of obstruction for 8 weeks. Tail suspension deflection experiment, balance beam experiment and water maze test were performed in the 2nd, 4th and 8th weeks. After 8 weeks, TTC staining was used to observe the volume of infarct atrophy, transcriptome sequencing was employed to screen differential expressed genes （DEGs） and highly enriched pathways were analyzed, Western-bloting and Elisa were used to assess proteins expression related to the pyroptosis pathway and inflammatory cytokines IL-1β and IL-18. Results By long-term administration of nicotiflorin, the contralateral deflection rate was significantly reduced and beam experiment score of CIRI rats was balanced, the number of crossing the platform in water maze test was increased （P<0.05）, the volume of cerebral infarction atrophy was decreased （P<0.01）, which significantly promoted the recovery of neurological function in rats. Transcriptome sequencing found that the expression of genes in the pyroptosis-related signaling pathways in the brain tissue of rats in the nicotiflorin group was significantly down-regulated （P<0.05）. Western-blot and Elisa experiments showed that nicotiflorin reduced the expression levels of Caspase-1 and GSDMD-N and other pyroptosis-related proteins, and at the same time, the release of inflammatory factors IL-1β and IL-18 was significantly reduced （P<0.05）, indicating that nicotiflorin could inhibit the inflammatory process of pyroptosis. Conclusion Nicotiflorin exhibited a significant long-term promotion effect on the recovery of neurological function in CIRI rats, which potentially attributed from its ability to inhibit pyroptosis.

Objective To evaluate the rehabilitative effect of targeted sonic vibration load brushing method in stroke patients with oral phase swallowing disorders.Methods A total of 60 stroke patients with swallowing disor-ders,who hospitalized in the rehabilitation department of a Grade Ⅲ Class A hospital in Nanjing City from October 2023 to May 2024,were randomly assigned to an experimental group and a control group,with 30 patients in each group.Both groups received the conventional swallowing function training.The experimental group received targeted sonic vibration load brushing therapy,while the control group received routine oral care with manual toothbrushes.After 30 days of intervention,the swallowing function(Gugging Swallowing Screen,GUSS),modified Beck oral score,incidence of swallowing disorder-related complications,Swallowing Quality of Life(SWAL-QOL)scores,and oral care satisfaction were assessed in both groups.Results No sample detachment.After the intervention,the GUSS score for the experimental group was significantly higher than that of the control group,with a statistical difference(Z=-4.239,P＜0.001).Additionally,the modified Beck oral score and the overall complications rate related to swallowing disor-ders in the experimental group were significantly lower than those in the control group(both P＜0.05).Furthermore,the SWAL-QOL score and the oral care satisfaction score were both higher in the experimental group compared to those in the control group,with statistically significant differences(both P＜0.001).Conclusion Targeted sonic vibration load brushing method significantly improves swallowing function,enhances oral cleanliness,reduces the occurrence of swallowing disorder-related complications,and effectively improves patients' quality of life and nursing satisfaction.

Recent studies indicate that paternal exposures significantly affect offspring health.Adverse factors such as poor diet,toxin exposure,and stress can reduce semen quality and disrupt epigenetic marks in sperm,leading to changes in off-spring traits.Paternal transgenerational inheritance mainly occurs through epigenetic factors like DNA methylation,histone modi-fication,and non-coding RNAs.While researches have begun to reveal how sperm transmits epigenetic information,paternal epi-genetics largely remains correlational.Increasing concerns about environmental pollution and lifestyle changes have shifted focus to paternal sperm quality and its impact on offspring health before conception.Future studies should explore how different envi-ronmental and male infertility factors influence paternal epigenetics and how specific marks affect embryonic development,ulti-mately enhancing diagnostics,treatments,and preconception care.

Objective:To investigate the potential of praeruptorin A (PA) in alleviating inflammatory damage in sepsis through the inhibition of ferritin expression.Methods:C57BL/6 mice were intraperitoneally injected with lipopolysaccharide (LPS) to establish the model of sepsis. After 6 and 12 h of PA intervention, serum levels of inflammatory cytokines IL-6 and TNF-α were measured by ELISA. Kidney tissues were collected at 72 h for HE staining to assess inflammatory cell infiltration and tissue damage. Human neutrophils were divided into four groups: control, LPS, ferritin, and LPS+ ferritin groups. After 12 h of intervention, qRT-PCR was used to detect the expression of IL-6 and TNF-α mRNA. In order to observe the effect of PA on the expression of inflammatory cytokines and ferritin, human neutrophils were grouped into control, LPS, and LPS+ PA (2/3/4 μmol/L) groups. After 12 h of intervention, qRT-PCR was performed to measure the expression of IL-1β, IL-6, TNF-α, and ferritin mRNA; ELISA was used to quantify the levels of IL-1β, IL-6, and TNF-α in culture supernatants; Western blot was used to analyze the expression of ferritin. Molecular docking was conducted to verify interactions between PA and ferritin.Results:Significant inflammatory cell recruitment, tissue damage, and elevated serum levels of IL-6 and TNF-α ( P<0.01) were observed in mice with LPS-induced sepsis. PA significantly inhibited cytokine secretion ( P<0.01) and alleviated tissue injury in sepsis mice. In human neutrophil models, ferritin upregulated the expression of IL-6 and TNF-α mRNA ( P<0.01); LPS stimulation alone increased the expression of IL-1β, IL-6, TNF-α, and ferritin at both mRNA and protein levels ( P<0.01), while co-stimulation with PA (3/4 μmol/L) significantly reversed the aforementioned results ( P<0.01). Molecular docking confirmed there were interaction sites between PA and ferritin. Conclusion:PA inhibits the release of inflammatory cytokines and alleviates tissue damage in sepsis, and the potential mechanism may involve modulating ferritin expression to suppress inflammatory responses.

Objective To construct a hierarchical dynamic management intelligent system for nurses and to validate its application effectiveness,providing a reference for the development of intelligent nursing human resource management.Methods The nurse hierarchical classification and dynamic promotion management mechanism were clarified,and a hierarchical dynamic management system for nurses was established,comprising 2 modules:personal growth,and tier management and review.The system was officially implemented in a tertiary A hospital in Henan Province in March 2024.A comparison was conducted between pre-implementation(2023)and post-implementation(2024),including nurse tier applications and promotions,efficiency in tier promotion evaluations,Psychological Capital Questionnaire scores of nurses,and user satisfaction with the system.Results Following the implementation of the hierarchical dynamic management intelligent system for nurses,the application rate for tier promotion increased by 11.33％.After system implementation,the promotion pass rate and Psychological Capital Questionnaire scores of nurses were significantly higher than those before implementation,while the time required for tier review was significantly shorter.These differences were statistically significant(P＜0.05).The satisfaction survey scores for nurses applying for tier promotion and for reviewers using the system were(62.28±4.56)and(64.09±3.17)scores,respectively.Conclusion The application of the hierarchical dynamic management intelligent system for nurses helps enhance nurses'promotion pass rates and psychological capital,streamlines the nurse tier review process,and demonstrates high user satisfaction with the system.

Objective:To identify strain-specific features of Klebsiella pneumoniae by analyzing metagenomics next generation sequencing (mNGS) data, thereby expanding the downstream applications of mNGS. Methods:The sequences of K.pneumoniae strains were organized from both the self-built database of the long-term multi-center research cohort in China established by the Peking University People′s Hospital from 2009 to 2020 (with 2 345 sequences) and the public databases (with 19 648 sequences). The existing large-scale databases were compressed, and a set of strains representative of clonal groups were screened. A strain genome information library was constructed based on k-mer features, and the most matching representative sequences in the database were searched for the raw mNGS data. The search results of the self-built library and public library were merged and optimized to update the prediction of antimicrobial-resistance characteristics and avoid the impact of uneven data distribution on the results. A total of 314 clinical samples from patients with K.pneumoniae detected by mNGS in the Clinical Microbiology Laboratory of Peking University People′s Hospital from 2022 to 2024 were retrospectively collected, and 101 samples with positive clinical culture results were selected to validate the prediction results. The antimicrobial-resistance phenotypes were verified by clinical antimicrobial susceptibility test results. Whole-genome sequencing was performed on the culture strains of 14 samples randomly selected using random numbers to verify the genotypes. Single nucleotide polymorphism distance analysis was used to verify the occurrence of outbreak events. The χ2 test and Mann-Whitney U test were used for statistical analysis. Results:A representative strain sequence k-mer feature library containing self-built and public sub-libraries was constructed. The library construction required only about 1 hour with <3 GB storage, with a high compression ratio and low update cost. Using k-mer-based analysis, mNGS data achieved precise strain characterization within 4 minutes and and <5 GB memory occupation. There was a significant difference in the antimicrobial-resistance rates to more than half of the antibiotics between the self-built database (90.8%, 2 130/2 345) and the public database (22.7%, 4 457/19 648) ( χ2=4 634.1, P<0.001). After optimizing the search results, the mean category agreement, sensitivity, and specificity of the prediction for eight antibiotics reached 84.8% (323/381), 78.9% (131/166), and 91.2% (196/215), respectively. The target genotypes were successfully detected in 10 out of 12 samples, and two outbreak events (2 samples per event) were successfully identified. Conclusions:An independent analysis process adapted to the needs of identifying the features of K. pneumoniae strains in mNGS data was developed. This process requires minimal computational resources and processing time and can directly achieve the simultaneous analysis of the antimicrobial-resistance phenotypes of K. pneumoniae at the strain level and their corresponding genomic characteristic profiles based on the raw mNGS reads.
