ObjectiveTo verify the technical feasibility and safety of partial nephrectomy in experimental pigs using a single-port endoscopic surgical robot in a transcontinental ultra-remote environment spanning 13 000 km with an average network delay of 204 ms, and to explore a dynamic combined anesthesia strategy that can effectively prevent intraoperative body movement in animals. MethodsThe research team used one experimental pig in Shanghai, China, and one in Orlando, the United States, and performed bidirectional remote surgery using the same model of single-port endoscopic surgical robot system. The anesthesia regimen included preoperative administration of 0.02 mg/kg dexmedetomidine hydrochloride and 0.05 mg/kg fentanyl citrate for combined sedation and analgesia. During remote surgery, according to the animal's reflex activity, pain response, and train-of-four stimulation (TOF) count results, vecuronium bromide was continuously infused at an initial rate of 0.04 mg·kg^-1·h^-1, and the dose was dynamically adjusted. Together with isoflurane inhalation anesthesia, the animal was maintained in a deep neuromuscular block state (TOF=0) to prevent intraoperative body movement. In addition, heart rate, blood pressure, muscle relaxation, and other indicators were monitored throughout the operation. ResultsSurgical operations were successfully performed at both sites, and the network delay remained stable at 202-208 ms. There was no data packet loss and no robot equipment failure. The vital signs of the experimental animal in Shanghai, China, remained stable, with zero body movement throughout the operation. Intraoperative blood loss was controllable, and no abnormal bleeding occurred. ConclusionIn transcontinental ultra-remote robotic surgery with inherent network delay, a dynamically adjusted anesthesia strategy can effectively avoid accidental bleeding caused by animal body movement and reduce the risks associated with network latency, thereby verifying the feasibility of this technical approach. In the future, it will be necessary to build a real-time cross-regional physiological data synchronization platform, standardize anesthesia protocols for animals undergoing remote surgery, and provide a technical basis for clinical translation to human trials.

Objective To understand the impact of bed-making manipulation on the air surrounding bed units in hemodialysis room,evaluate the effectiveness of routine terminal disinfection,and provide scientific basis for optimi-zing infection control measures.Methods Air specimens(pre-bed-making group)and environmental object surface specimens(pre-terminal disinfection group)around bed units were collected when hemodialysis was about to be fi-nished.Air specimens after bed-making(bed-making group)and environmental object surface specimens after ter-minal disinfection(terminal disinfection group)were also collected.Bacterial colonies were counted and identified.Results A total of 714 air specimens were collected from 238 bed units of 45 hemodialysis units before and during bed-making.The average bacterial colony count during bed-making was higher than that before bed-making([2.72±3.43]CFU/plate vs[0.69±1.50]CFU/plate,P＜0.05).The qualified rate of microbial colony count before bed-making was higher than that during bed-making(96.64％vs 64.71％,P＜0.05).A total of 450 environmental ob-ject surface specimens from 90 bed units of 45 hemodialysis units were collected before and after terminal disinfec-tion.The average bacterial colony count before terminal disinfection was higher than that after terminal disinfection([8.18±20.6]CFU/cm2 vs[1.49±3.44]CFU/cm2.P＜0.05).The qualified rate of microbial colony count after terminal disinfection was higher than that before terminal disinfection(98.22％vs 92.44％,P＜0.05).The micro-organisms in the air and environment were mainly coagulase negative Staphylococcus.Conclusion Bed-making has a certain impact on the air microorganisms around the bed units,and terminal disinfection can reduce the bacterial co-lony count of the environment.It is necessary to pay attention to the cleaning and disinfection of the environment for medical treatment,and carry out bed-making manipulation under clear condition to minimize the risk of infection.

Objective To understand the experience of fall alertness in elderly patients with rheumatoid arthritis and to provide references for the development of targeted nursing intervention strategies.Methods 13 elderly patients with rheumatoid arthritis,who were admitted to the Department of Rheumatology and Immunology of a tertiary hospital in Guizhou Province from February to April 2024,were selected through purposive sampling.Phenomenological qualitative research methods were used,with semi-structured in-depth interviews.Data were analyzed using Colaizzi's seven-step method,and themes were extracted.Results 3 main themes and 9 sub-themes were identified:the process of fall risk perception(reshaping fall risk cognition,establishing emotional coping mechanism,enhancing fall alertness effect),behavioral responses to fall alertness(creating a safe living environment,regularizing daily routine plan),and needs for fall prevention support(need for fall prevention knowledge,home rehabilitation care needs,intelligent device usage needs,psychosocial support needs).Conclusion Clinical medical staff should pay attention to the transformation process of fall risk perception in elderly rheumatoid arthritis patients,accurately identify patients'fall support needs in practice,and guide patients to adopt appropriate fall alert response behaviors through innovative fall demand support interaction paths and the construction of social support network systems,in order to improve patients'fall alertness and reduce their fall risk.

Objective:To explore the mediating effect of illness acceptance between self-compassion and rehabilitation motivation in stroke patients with partial disability.Methods:By convenience sampling method, stroke patients who attended the neurology outpatient clinic of Xinxiang Central Hospital from February to December 2024 were selected as the research subjects. The General Information Questionnaire, Self-Compassion Scale (SCS), Chinese version of Acceptance of Illness Scale (AIS-CHI), and Stroke Rehabilitation Motivation Scale (SRMS) were used for the survey. Pearson correlation analysis was applied to analyze the relationships among self-compassion, illness acceptance, and rehabilitation motivation. AMOS 21.0 software was used to establish a structural equation model and verify the mediating effect.Results:A total of 300 questionnaires were distributed, and 289 valid ones were recovered, with an effective recovery rate of 96.33%. Among the 289 stroke patients with partial disability, the total score of SCS was (65.73±5.50), the total score of AIS-CHI was (17.46±5.62), and the total score of SRMS was (77.18±10.97). Pairwise positive correlations were found between self-compassion, illness acceptance, and rehabilitation motivation (all P<0.05). Self-compassion had a direct positive effect on rehabilitation motivation ( β=0.328, P<0.01) and a direct positive effect on illness acceptance ( β=0.439, P<0.01). Illness acceptance played a partial mediating role between self-compassion and rehabilitation motivation, and the mediating effect accounted for 31.38% of the total effect (0.150/0.478) . Conclusions:The levels of self-compassion, illness acceptance, and rehabilitation motivation in stroke patients with partial disability need to be further improved. Illness acceptance exerts a partial mediating effect between self-compassion and rehabilitation motivation. Clinically, the rehabilitation motivation of patients can be enhanced by improving their levels of self-compassion and illness acceptance.

Hereditary angioedema (HAE) is a rare autosomal dominant genetic disorder characterized by recurrent episodes of subcutaneous and submucosal edema, which can be life-threatening in severe cases. Lanadelumab, a recombinant human monoclonal antibody against kallikrein, has been recommended as a first-line option for long-term prophylaxis of HAE. This paper analyzed the clinical data of four patients with HAE diagnosed and treated with lanadelumab for long-term prophylaxis in our department since 2020. It also reviewed relevant literature, summarizing the clinical manifestations of HAE, as well as the efficacy and safety of lanadelumab in treating HAE, to provide therapeutic references for clinicians.
