Objective To explore the effect of hyperbaric oxygen combined with synchronous brain bionic electrical stimulation on patients with stroke-related sleep disorders.Methods From November,2023 to November,2024,a total of 68 stroke patients with stroke-related sleep disorders ad-mitted to Huashan Hospital,Fudan University were selected.They were randomly divided into control group(n=34)and experimental group(n=34).The control group received routine hyperbaric oxygen therapy,while the ex-perimental group received routine hyperbaric oxygen therapy combined with synchronous brain bionic electrical stimulation inside the chamber,for four weeks.Pittsburgh Sleep Quality Index(PSQI),sleep-monitoring wrist-bands,Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS)were used to assess the outcomes before and after treatment..Results Four patients in the control group and one in the experimental group dropped out.After treatment,the scores of each factors of PSQI decreased in both groups(t>2.693,P<0.05),and were lower in the experimental group than in the control group(t>2.699,P<0.01),expect hypnotic drug use(P>0.05);the total sleep time,deep sleep time and rapid eye movement sleep time became longer in both groups(|t|>7.270,P<0.001),and they were longer in the experimental group than in the control group(|t|>5.712,P<0.001);the scores of SAS and SDS decreased in both groups(t>9.530,P<0.001),and they were less in the experimental group than in the control group(t>4.740,P<0.001).Conclusion Synchronous brain bionic electrical stimulation in hyperbaric oxygen chamber could effectively prolong the total sleep time,deep sleep time and rapid eye movement time of patients with stroke-related sleep disorders,re-lieve anxiety and depression after stroke,and improve sleep quality.

Objective To explore the differences in neural activity between patients with anorexia nervosa(AN)and healthy controls(HC),as well as the association between these differences and symptoms in AN patients,using activation likelihood estimation(ALE)meta-analysis.Methods The literature search covered the period from 2000 to March 2025.From a pool of 588 identified studies,4 studies focusing on the neural activity differences between AN patients and HC were selected for inclusion.These studies comprised 106 participants and 21 sets of coordinates.The ALE meta-analysis method was employed,and the GingerALE software was used to systematically analyze the reported brain region changes and their peak coordinates,aiming to investigate the differences in brain functional activity between AN patients and HC.Results Compared to the HC group,AN group showed significantly enhanced activation in the left parahippocampal gyrus/amygdala(ALE value=0.39×10-2),right parahippocampal gyrus/amygdala(ALE value=0.39×10-2)and suboccipital gyrus(ALE value=0.39×10-2),along with a significant reduction in activation in Brodmann area 17(ALE value=0.61×10-2)(P<0.01,FWE corrected).Conclusion Key brain regions in AN patients including the parahippocampal gyrus,inferior occipital gyrus,and amygdala demonstrate significant functional activation abnormalities.

Objective:To develop an exercise rehabilitation program based on the Temporal Self-regulation Theory and evaluate its effectiveness in elderly patients with hip fractures.Methods:A total of 84 elderly patients with hip fractures admitted to the Department of Trauma Orthopedics at the First Affiliated Hospital of University of South China from May to August 2024 were enrolled using convenience sampling. Participants were randomly assigned to an experimental group ( n=42) and a control group ( n=42) using a random number table. The control group received routine exercise rehabilitation, while the experimental group received an exercise rehabilitation program constructed based on the Temporal Self-regulation Theory. The program included components such as establishing a unified concept of "exercise-rehabilitation", enhancing time-limited efficacy, achieving behavioral advantages, and improving self-regulation of active movement. Both groups received interventions for 12 weeks. Functional exercise adherence, activities of daily living, and hip joint function were assessed using the Orthopedic Exercise Adherence Scale, Modified Barthel Index, and Harris Hip Score at four time points: before intervention, on the day of discharge, and at 4 and 12 weeks postoperatively. Results:During the study, two patients from each group dropped out. Results of the generalized estimating equations showed group effects, time effects, and interaction effects in adherence scores with statistically significant differences ( P<0.01). On the day of discharge, and at 4 and 12 weeks postoperatively, the adherence scores in the experimental group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05). Repeated measures ANOVA indicated that group effects, time effects, and interaction effects were also statistically significant in scores for daily living ability and hip joint function ( P<0.05). The experimental group scored higher than the control group at each time point with statistically significant differences ( P<0.05) . Conclusions:The exercise rehabilitation program based on the Temporal Self-regulation Theory is scientifically sound and practical. It can effectively improve functional exercise adherence, enhance daily living ability, and promote postoperative recovery of hip joint function in elderly patients with hip fractures.

Sennoside A (SA), a typical prodrug, exerts its laxative effect only after its transformation into rheinanthrone catalyzed by gut microbial hydrolases and reductases. Hydrolases have been identified, but reductases remain unknown. By linking a photoreactive group to the SA scaffold, we synthesized a photoaffinity probe to covalently label SA reductases and identified SA reductases using activity-based protein profiling (ABPP). From lysates of an active strain, Bifidobacterium pseudocatenulatum (B. pseudocatenulatum), 397 proteins were enriched and subsequently identified using mass spectrometry (MS). Among these proteins, chromate reductase/nicotinamide adenine dinucleotide (NADH) phosphate (NADPH)-dependent flavin mononucleotide (FMN) reductase/oxygen-insensitive NADPH nitroreductase (nfrA) was identified as a potent SA reductase through further bioinformatic analysis and The Universal Protein Resource (UniProt) database screening. We also determined that recombinant nfrA could reduce SA. Our study contributes to further illuminating mechanisms of SA transformation to rheinanthrone and simultaneously offers an effective method to identify gut bacterial reductases.
