Objective To investigate the status of intrinsic capacity (IC) in elderly inpatients and explore its correlation with sarcopenia and frailty. Methods A total of 320 elderly inpatients hospitalized from October 2021 to October 2024 were enrolled in this study. IC, frailty status, risk of sarcopenia, and basic activities of daily living were evaluated using the IC Comprehensive Assessment Tool, the Frailty Syndrome Rapid Screening Scale, the five-item Sarcopenia Index, and the Barthel index. The correlation between IC and sarcopenia and frailty in elderly inpatients was explored by logistic regression analysis. Results The average IC score, frailty score, 5-item sarcopenia scale score, and incidence rate of positive sarcopenia screening in the elderly inpatients were (4.08±0.52) points, (1.57±0.42) points, (3.84±0.59) points, and 33.75% (108/320), respectively. Logistic regression analysis showed that Barthel index (OR=0.286, 95%CI: 0.128-0.641, P=0.002), sarcopenia (OR=3.762, 95%CI: 1.793-7.892, P<0.001) and frailty (OR=1.236, 95%CI: 1.090-1.401, P=0.001) were the independent influencing factors for IC in the elderly. Conclusion IC decline is common in elderly patients, and elderly inpatients with sarcopenia, frailty or poor self-care ability have a higher risk of IC damage.

ObjectiveTo explore the complex network relationships among pain, kinesiophobia, social participation and knee function in patients after total knee arthroplasty (TKA), and to analyze the moderating effects of different socio-structural factors on the rehabilitation network from an ethical equity perspective. MethodsA convenience sampling method was used to select 291 patients who underwent TKA in Qilu Hospital of Shandong University from May to July, 2023. Pain was assessed using Numerical Rating Scale, kinesiophobia with Chinese short version of the Tampa Scale for Kinesiophobia, social participation with Impact on Participation and Autonomy Questionnaire, and knee function with Hospital for Special Surgery Knee Score. A partial correlation network among pain, kinesiophobia, social participation and knee function was constructed using Graphical Least Absolute Shrinkage and Selection Operator. Key variables were identified through node centrality and bridge centrality analysis. Network Comparison Tests (NCT) were used to analyze network differences among subgroups based on different socio-structural characteristics. ResultsIn the network model, the nodes with the highest strength centrality were indoor participation, activity behavior and activity pain. Bridge centrality analysis indicated that activity pain, knee function, indoor participation and activity cognition were key bridge nodes. NCT revealed no significant differences in overall network structure or global strength among subgroups based on residence, education level or payment method (P > 0.05). However, significant differences in edge weights were found for specific edges such as activity cognition-activity behavior and knee function-indoor participation (P < 0.05). ConclusionThere is a network of interactions among pain, kinesiophobia, social participation and knee function in patients after TKA, with nodes such as indoor participation and activity pain playing key roles in the rehabilitation process. Although the overall rehabilitation network is similar across different socio-structural groups, variations exist in specific relational pathways among patients from rural areas, those with lower education levels, and those with out-of-pocket payment. This suggests that clinical rehabilitation interventions should focus on these core nodes and implement targeted support strategies for socio-structurally disadvantaged groups to promote rehabilitation equity.

ObjectiveTo explore ethical dilemmas in amputation treatment, focusing on patient autonomy, informed consent and decision-making interaction between family members and medical teams, to provide references for clinical ethical decision-making and rehabilitation practice. MethodsThe decision-making process of amputation was analyzed from three dimensions, including patient autonomy, informed consent and shared decision-making of families and medical teams, in light of ethical principles such as non-maleficence, beneficence and justice. ResultsEthical decision-making in amputation was based on adequate informed consent of patients and their families. Medical teams made decisions on the premise of respecting patients' true will. Postoperative psychological support and social security system played a vital role in patients' rehabilitation, and national policy support was indispensable. ConclusionEthical decision-making for amputation should balance the responsibilities of medical teams and family participation on the basis of respecting patient autonomy and ensuring informed consent. Sound postoperative psychological support and social security system are essential for patients' comprehensive rehabilitation, which should be fully considered in clinical ethical practice.

With the rapid development of artificial intelligence （AI） technology， the ethical governance of AI has gained increasing attention. The Recommendation on the Ethics of Artificial Intelligence was issued by the United Nations Educational， Scientific and Cultural Organization in 2021， which clarified several principles for the ethical governance of AI. In the field of rehabilitation medicine， the research and application of AI technology have significantly improved patients’ quality of life and survival. However， due to the specificity of the service population in rehabilitation medicine， which is mostly for the sick， injured， disabled， and elderly， a series of complex ethical issues have also arisen. This paper analyzed in detail the ethical issues and challenges encountered in the research and application of AI technology in the field of rehabilitation medicine from various aspects， such as informed consent， security of privacy and data， patients’ physical and mental rehabilitation， compliance regulation， protection of specific groups， and promotion of equity. According to the principles of the Recommendation on the Ethics of Artificial Intelligence and others， response strategies were proposed， including multi-party collaboration and interdisciplinary cooperation， improving and refining relevant laws and regulations， strengthening ethical education across society， establishing accountability mechanisms， increasing investment， promoting equity， and other measures， to promote the healthy development of research and application of AI technology in the field of rehabilitation， as well as benefit humanity.

Objective:To explore the effect of exercise on glycemic control and physical indicators among community-dwelling persons with type 2 diabetes mellitus (T2DM).Methods:A total of 42 T2DM patients undergoing regular follow-up at a community health center were divided into a control group and an exercise group. To minimize confounding factors, 1∶1 propensity score matching was performed, resulting in 21 patients in each group. Both groups received standardized diabetes management, including medication, dietary guidance and diabetes health education. The exercise group additionally performed exercises which integrated sports and medical care models. The experiment lasted 8 weeks. Before and after the intervention, glycosylated hemoglobin A1c (HbA1c) levels, body weight, body mass index (BMI), fat mass, visceral fat area (VFA), fat mass index (FMI) and appendicular skeletal muscle mass index (ASMI) were recorded and compared between the two groups. Moreover, the actual exercise compliance of the exercise group was observed, along with any adverse events such as hypoglycemia or exercise-related injuries, as well as changes in antidiabetic medication dosage.Results:After the intervention, significant improvement was observed in both groups in all of the measurements, but with the average HbA1c, BMI, fat mass, VFA and FMI values of the exercise group then significantly better than the control group′s averages. The average compliance rate in the exercise group was 60%. No cases of hypoglycemia or exercise-related injuries were reported during the intervention, and there were no changes in the use of anti-diabetes medications.Conclusions:Exercise effectively improves glycemic control and physical indicators among community-dwelling T2DM patients. However, exercise compliance needs improving.

Radiation-induced skin injury can occur following multiple radiotherapy treatments or nuclear accidents, significantly impacting patients’ quality of life. Radiation-induced skin ulcers often fail to heal and currently lack effective treatment options. Previous studies have demonstrated that cellular senescence is a critical factor contributing to the impaired healing of these ulcers. This article reviews the occurrence and progression of radiation-induced skin damage, the role of cellular senescence in wound healing, potential mechanisms and related biomarkers, and explores the significance of removing senescent cells in alleviating radiation-induced skin damage. It is hoped that this review will provide new insights for the treatment of radiation-induced skin injuries.

Objective:To evaluated the efficacy and safety of eltrombopag in patients with systemic lupus erythematosus (SLE)-related refractory immune thrombocytopenia (ITP).Methods:Nine patients with severe SLE-associated refractory ITP were recruited the People's Hospital of Xinjiang Uygur Automomous Region from Septermber 2021 to February 2024 and received eltrombopag 50 mg orally daily for 1 month; basic patient information, platelet counts, other laboratory parameters and adverse events were recorded. Normally distributed continuous data were expressed as mean±standard deviation ( Mean±SD) and compared using paried samples t-test; non-normally distributed data were presented as median (interquartile range) [ M( Q1, Q3)]; categorical variables were described as n (%). Results:Eight participants (88.9%) completed the study, and at 1 month, five patients showed significant improvement in subcutaneous bleeding and erythema of the skin and mucous membranes, and three patients showed significant relief of joint and muscle involvement, and the patients′ platelet counts were (16.9±9.6)×10 9/L before treatment and increased to (114.0±53.9)×10 9/L. Differences in platelet levels before and after treatment in intergroup comparisons ( t=-4.881 , P=0.002), of which 4 patients achieved complete remission of platelet involvement, 3 patients achieved partial remission of platelet involvement, 4 cases were significantly efficacious and 3 cases efficacious. Follow-up data showed that platelet counts remained normal with no significant adverse events and one patient discontinued the study after 2 weeks of eltrombopag due to abnormal blood counts. Conclusion:Eltrombopag may be a promising new option for patients with SLE-associated refractory ITP with satisfactory remission rates, but large sample studies are needed for validation.

Objective:To explore the efficacy and safety of intense pulsed light (IPL) for facial early linear scars.Methods:The patients who underwent facial plastic surgery and cosmetic suturing at the Department of Plastic and Aesthetic Surgery, the Second Affiliated Hospital of Soochow University from June to December 2023 were included. A randomized self-controlled study was conducted. Each post-operative wound was divided into the treatment and control sides by random number. The treatment side received 3 sessions of IPL treatment at 2-3 d after wound suturing, 6-7 d after suture removal and 6 weeks after surgery, respectively. The control side did not receive IPL treatment. After 3 months follow-up, the Vancouver scar scale (VSS), patient and observer scar assessment scale (POSAS) were used to evaluate the scars on both sides. Adverse reactions were recorded. VSS evaluated scar severity through four items: vascularity (0-3 points), pigmentation (0-3 points), thickness (0-4 points), and pliability (0-5 points), with a total score of 0-15 points. The higher the score, the more serious the scar was. POSAS consisted of observer scar assessment scale (OSAS) and patient scar assessment scale (PSAS), OSAS included vascularity, pigmentation, thickness, surface relief, pliability, surface area and overall opinion. While PSAS included pain, itching, color, thickness, stiffness, irregularity, and overall opinion. Each component was assessed on a scale ranging from 1 to 10, while maximum scores indicated the worst outcome. Statistical analysis was performed using the Graphpad Prism 8.0 software. Normal distributed measurement data were expressed as Mean±SD, and non-normally distributed measurement data were expressed as M( Q1, Q3). Comparisons of VSS, OSAS, PSAS scores between the treatment and control sides were performed using paired sample t-test or paired sample Wilcoxon rank sum test. P<0.05 was considered statistically significant. Results:A total of 23 facial trauma patients with 27 scars formed after debridement and aesthetic suture were enrolled in this study, including 17 males and 6 females, aged (28.2±6.1) years old. The length of the scars were (5.9±1.8) cm. After three sessions of treatment and 3 months follow-up, with regard to VSS, the treatment sides scored vascularity [0(0, 1) vs. 1(1, 1)], thickness [0(0, 0) vs. 0(0, 1)], and total scores [0.5(0, 1) vs. 1(1, 2.75)], which were statistically lower than the control sides (all P<0.05). With regard to OSAS, the treatment sides scored vascularity(2.1±0.9 vs. 3.0±1.0), pigmentation(2.2±0.8 vs. 2.3±0.8), thickness(1.4±0.7 vs. 1.9±0.9), surface relief(1.7±0.6 vs. 2.2±1.1), pliability(1.8±0.8 vs. 2.1±1.1), overall opinion(1.9±0.8 vs. 2.8±1.1) and total scores(12.6±4.4 vs. 16.2±6.2), which were statistically lower than the control sides(all P<0.05).With regard to PSAS, the treatment sides scored scar color(2.9±1.3 vs. 3.9±1.7), thickness(1.8±1.4 vs. 2.4±1.5), overall opinion(2.2±1.0 vs. 3.1±1.3) and total scores(14.3±6.7 vs. 17.7±7.7), which were statistically lower than the control sides(all P<0.05). No adverse reactions such as wound infection, delayed wound healing and blister formation were observed in all patients. Conclusion:IPL is effective in the treatment of early facial scars, which can significantly improve the vascularity, thickness, pigmentation, surface relief and pliability of scars, and improve the scars appearance. This treatment method is safe with few adverse reactions.
