The Integration of Sports and Health forms an essential part of China's distinctive public health service system, and the prevention and treatment of chronic diseases and active health of the elderly group are important practice directions of physical and health integration.Research highlights that this approach effectively supports cardiovascular health, addresses musculoskeletal disorders, alleviates neurodegenerative conditions, and enhances mental well-being, thereby contributing positively to chronic disease prevention and management in the elderly population.Currently, community organizations and professional institutions are the primary providers of these services in China.Looking ahead, the development of elderly-oriented sports and health integration services in China should focus on ensuring institutional and policy support, promoting health-conscious ideologies, delivering high-quality services, and cultivating a skilled professional workforce, as well as establishing a standardized evaluation system.

Objective:To explore the gait and eye movement parameters in early Parkinson's disease(PD)with sleep disorders, and analyze their association with underlying pathophysiological mechanisms.Methods:This study was a cross-sectional single-center design that included 82 early PD patients with Hoehn-Yahr(H-Y)staging ≤2.5 who visited Beijing Hospital from October 2023 to May 2025.Patients were divided into two groups according to the PDSS-2 score(total score ≤15 for the no sleep disorder group and total score >15 for the sleep disorder group). Gait and eye movement parameters were collected respectively through the ReadyGo system and the EyeKnow eye movement system, and analyzed in combination with clinical scales.Multivariate logistic regression was employed to identify independent characteristic parameters associated with sleep disorders.Results:In terms of gait, the sleep disorder group had significantly lower step speed, left-right stride speed, and left-right swing speed(all P<0.05), and significantly higher variability of left-right stride time( P=0.017, 0.026). Regarding eye movements, the sleep disorder group had significantly more vertical smooth pursuit offsets[(56.24±2.87)times vs.(45.98±18.18)times, P=0.040], significantly higher maximum real-time variability of the right eye in response to light stimuli(90.75 vs.67.95%, P=0.006), and a longer latency to error responses in the counter-scanning task(337.06 vs.286.63 ms, P=0.005). To precisely control for confounding factors, key covariates such as mood and disease severity were included in the multivariate logistic regression model.After comprehensive adjustment, higher anxiety levels(Hamilton Anxiety Rating Scale, HAMA)( OR=1.32, P<0.001)and an increased number of vertical smooth pursuit offsets( OR=1.06, P=0.010)were independent factors associated with sleep disorders in early PD patients. Conclusions:In early PD patients, sleep disorders are closely associated with specific abnormalities in gait and eye movement parameters.In particular, vertical smooth pursuit offsets may serve as an objective biomarker independent of emotional status, reflecting the dysfunction of shared neural circuits.However, further mechanism studies are needed to verify whether they reflect the dysfunction of shared neural circuits.

Objective:To evaluate gait characteristics in early-stage Parkinson′s disease (PD) patients using an artificial intelligence-based quantitative motor function assessment system (Readygo) and validate whether PD patients with clinically normal gait actually exhibit objective gait impairments, and to explore the features and progression patterns of gait dysfunction in early PD.Methods:This cross-sectional, single-center study enrolled early-stage PD patients (Hoehn-Yahr stage≤2.5) from outpatient or inpatient departments of Beijing Hospital between October 2023 and October 2024, along with accompanying caregivers as healthy controls (HCs). Demographic data (sex, age, education level) were collected, and cognitive, psychological, and sleep-related scales assessments were administered. Based on the gait score (Item 3.10) from the Movement Disorder Society-Unified Parkinson′s Disease Rating Scale-Ⅲ (MDS-UPDRS-Ⅲ), PD patients were stratified into 3 subgroups: PD-normal gait (score=0), PD-mild gait impairment (score=1), and PD-moderate gait impairment (score=2). The Readygo system quantified gait parameters, including step width, stride length, step height, gait speed, stride velocity, swing velocity, and turn duration. Binary Logistic regression was uesd to identify biomarkers differentiating PD-normal gait group from HCs.Results:A total of 66 early-stage PD patients and 34 HCs were enrolled. Across the HCs, PD-normal gait, PD-mild gait impairment and PD-moderate gait impairment groups, there was a progressive decline in gait speed [1.07 (0.97, 1.15) m/s vs 0.97 (0.90, 1.06) m/s vs 0.90 (0.82, 1.00) m/s vs 0.77 (0.72, 0.86) m/s, H=29.949, P<0.001], bilateral stride velocity [left: 1.14 (1.07, 1.21) m/s vs 1.06 (0.94, 1.14) m/s vs 0.95 (0.88, 1.04) m/s vs 0.86 (0.76, 0.93) m/s, H=30.778, P<0.001; right: 1.12 (1.04, 1.22) m/s vs 1.04 (0.95, 1.13) m/s vs 0.96 (0.90, 1.04) m/s vs 0.89 (0.77, 0.90) m/s, H=29.561, P<0.001], and bilateral swing velocity [left: (2.56±0.28) m/s vs (2.38±0.32) m/s vs (2.19±0.33) m/s vs (1.96±0.32) m/s, F=14.132, P<0.001; right: 2.46 (2.35, 2.62) m/s vs 2.35 (2.13, 2.62) m/s vs 2.22 (2.05, 2.36) m/s vs 2.03 (1.71, 2.13) m/s, H=25.771, P<0.001], along with a progressive shortening of bilateral step length [left: 1.19 (1.14, 1.27) m vs 1.15 (1.04, 1.22) m vs 1.05 (0.93, 1.18) m vs 0.95 (0.80, 1.06) m, H=32.613, P<0.001; right: 1.20 (1.14, 1.30) m vs 1.13 (1.03, 1.22) m vs 1.07 (0.90, 1.17) m vs 0.97 (0.80, 1.03) m, H=30.528, P<0.001]. Conversely, turning time progressively lengthened [1.20 (1.09, 1.49) s vs 1.21 (1.10, 1.46) s vs 1.30 (1.19, 1.51) s vs 1.98 (1.53, 2.12) s, H=23.195, P<0.001]. Logistic regression identified that the right stride length was a discriminative factor between HCs and PD-normal gait group ( OR=0.023, 95% CI 0-0.291, P=0.012). Conclusions:As gait dysfunction worsens, PD patients demonstrate gradual reductions in speed-related parameters and stride length, with increasing turn duration.Early PD patients with clinically normal gait may already exhibit subtle impairments. Right stride length may serve as a potential biomarker to distinguish PD patients from HCs.

Objective:To construct an ultrasound-responsive nano-oxygen carrier，and to enhance cell survival within myocardial patches and promote myocardial infarction（MI）repair.Methods:Ultrasound-responsive phase-change nanobubbles（ND）were first prepared and integrated into GelMA hydrogel to construct myocardial patches. Low-intensity pulsed ultrasound（LIPUS）irradiation was applied to explore whether the nanobubbles could optimize the hydrogel properties. Hemoglobin（Hb）was further encapsulated into the nanobubbles to construct an oxygen carrier（ND-Hb）. In vitro and in vivo experiments were conducted to evaluate whether the optimized myocardial patches could improve cell survival and facilitate MI repair. In vitro，cell-loaded patches were divided into 6 groups（control，ND，Hb，LIPUS，LIPUS+ND，and LIPUS+oxygen carrier groups）to assess the cell viability and protein expression. In vivo，an acute MI model was established in SD rats，which were randomly assigned to 4 groups（control，Hb，LIPUS+ND，and LIPUS+oxygen carrier groups）.Myocardial patches were implanted，and cardiac function（echocardiography），cell survival（BLI imaging），angiogenesis（CD31 and α-SMA immunofluorescence）and connexin protein expression（Cx43）were evaluated. Results:Following the incorporation of ND and LIPUS irradiation，scanning electron microscopy revealed numerous micropores（about 2 μm）within the hydrogel were observed by scanning electron microscopy. The nano-oxygen carrier was successfully constructed，with a particle size of（301.2 ± 92.4）nm，and released oxygen under LIPUS stimulation. In vitro，at days 3，7，and 14，the cell survival rates in the LIPUS+oxygen carrier group［（89.6 ± 2.1）%，（79.3 ± 1.8）%，（70.9 ± Conclusions:This study successfully employs LIPUS combined with ND-Hb to enhance hydrogel properties，facilitating nutrient exchange within myocardial patches. Additionally，ultrasound-mediated oxygen release improves seed cell survival and promotes myocardial infarction repair.

Objective:To explore the current status and influencing factors of fatigue in patients with Cushing syndrome in China, so as to provide a basis for clinical interventions.Methods:Convenience sampling was used to select 260 inpatients with Cushing syndrome who met the inclusion and exclusion criteria in 9 ClassⅢ Grade A hospitals within the 7 geographic subregions of China from February to April 2023 for the study. General Information Questionnaire, the Chinese version of the Multidimensional Fatigue Inventory-20, Barthel Index, and Self-Rating Depression Scale were used for the survey.Results:A total of 260 questionnaires were distributed and 241 valid questionnaires were recovered, with an effective recovery rate of 92.7% (241/260). The MFI-20 score of 241 patients with Cushing syndrome was 58.00 (46.00, 64.00). 65.1% (157/241) of patients with Cushing syndrome suffered from fatigue, and 73.2% (115/157) of patients with fatigue exhibited multidimensional fatigue. Univariate analysis showed that there were statistically significant differences in fatigue scores among patients with Cushing syndrome with different cultural levels, recurrence frequency, activity of daily living, hypertension, and depression ( P<0.05). Multiple linear regression analysis showed that depression was a risk factor for fatigue in patients with Cushing syndrome, and the difference was statistically significant ( P<0.05) . Conclusions:Fatigue in patients with Cushing syndrome needs attention. Medical and nursing staff should pay close attention to the psychological status of patients with Cushing syndrome, encourage them to actively cope, alleviate their depression, in order to improve their fatigue.

Objective:To explore the latent profile characteristics of cancer-related fatigue (CRF) in breast cancer patients during the rehabilitation phase and to analyze the influencing factors of different latent profiles.Methods:A convenience sampling method was used to recruit 190 breast cancer patients in the rehabilitation phase from the follow-up cohort at Peking Union Medical College Hospital between March and May 2024. Data was collected using a general information questionnaire, the Cancer Fatigue Scale, the Self-Rating Anxiety Scale, the Self-Rating Depression Scale, the Pittsburgh Sleep Quality Index and the Visual Analogue Scale. Logistic regression analysis was conducted to identify the influencing factors of CRF latent profiles. A total of 190 questionnaires were distributed, and 183 valid responses were collected, yielding an effective response rate of 96.32% (183/190) .Results:Three latent profiles of CRF were identified: mild fatigue, moderate fatigue, and severe fatigue. Menopausal status, depressive symptoms, and pain scores were significant influencing factors of the CRF latent profiles ( P<0.05) . Conclusions:Cancer-related fatigue in breast cancer patients during the rehabilitation phase exhibits distinct latent profile characteristics. Early identification of profile types and associated influencing factors may provide a scientific basis for healthcare professionals to develop targeted clinical interventions to help patients alleviate fatigue.

BACKGROUND:A novel aggregation induced luminescence fluorescence probe based on the mechanism of intramolecular motility restriction can be used for the detection of disease markers,tumor diagnosis,and bacterial imaging recognition.OBJECTIVE:To prepare a near-infrared Ⅱ nanoprobe called FA-DSPE-PEG-AIE@NPs based on aggregation-induced luminescence,and to explore its potential of targeted fluorescence imaging and photothermal therapy for prostate cancer.METHODS:Lecithin,polyethylene glycol phospholipids,folate polyethylene glycol phospholipids,and aggregation induced luminescent molecule 2TT-oC26B were used as raw materials.The folate-targeted nanoprobe FA-DSPE-PEG-AIE@NPs were prepared by nanoprecipitation method,and basic characterization of the nanoprobe was detected.PC3 human prostate cancer cells and human umbilical vein endothelial cells were selected as experimental objects.The cytotoxicity and phototoxicity of FA-DSPE-PEG-AIE@NPs were detected.PC3 human prostate cancer cells were selected as the experimental objects.Flow cytometry and calcein/propidium iodide staining were used to assess the efficacy of photothermal therapy.PC3 human prostate cancer cells were injected subcutaneously into the abdomen of BALB/C nude mice to establish a tumor model,and nanoprobes FA-DSPE-PEG-AIE@NPs were injected into the tail vein.The mice were immediately subjected to near-infraced Ⅱ fluorescence imaging.12 hours later,the tumor was irradiated by laser for 5 minutes,and the photothermal treatment effect was observed within 14 days.RESULTS AND CONCLUSION:(1)The nanoprobes FA-DSPE-PEG-AIE@NPs with a mean diameter of(171.0±0.3)nm showed a well-defined spherical morphology.The nanoprobe had a wide absorption spectrum and tail emission extending to the near-infrared Ⅱ which emitted a bright near-infrared Ⅱ fluorescence signal under laser irradiation.(2)The nanoprobes FA-DSPE-PEG-AIE@NPs had low cytotoxicity and high phototoxicity.The results of flow cytometry and calcein/propidium iodide staining showed that nanoprobes FA-DSPE-PEG-AIE@NPs had an obvious photothermal killing effect on human prostate cancer cells.(3)The nanoprobes FA-DSPE-PEG-AIE@NPs successfully achieved near-infrared Ⅱ fluorescence imaging of mouse blood vessels and the maximum enrichment time of the tumor was 12 hours.The vessel widths of the hind leg and single blood vessels of abdomen were estimated to be 0.63 mm and 0.42 mm.The tumor volume of mice was significantly smaller after 14 days of treatment.(4)The results show that nanoprobes FA-DSPE-PEG-AIE@NPs can achieve near-infrared Ⅱ fluorescence imaging and photothermal therapy of prostate cancer effectively,which may provide a new method for early diagnosis and combined treatment of prostate cancer.

Objective:To apply the Timed Up and Go Test(TUGT)to investigate the correlation between motor function, emotional state, cognitive function, and sleep quality among elderly individuals in the Chinese community.Methods:A cross-sectional study was conducted, involving 739 subjects aged 60 to 90 years, who were randomly recruited from December 2021 to August 2023 across Beijing, Tianjin, Zhejiang, Guangdong, and Hainan Provinces in China.Basic demographic information was collected, and the TUGT was utilized to assess motor function.Based on the TUGT time(t), the subjects were divided into three groups: normal motor function group, mild motor abnormality group, and significant motor abnormality group.Cognitive function was evaluated using the Chinese Revised Mini-Mental State Examination(MMSE), while the Patient Health Questionnaire Depression Scale(PHQ-9)was employed to measure the degree of depression.Additionally, the Epworth Sleepiness Scale(ESS)was used to assess excessive daytime sleepiness.The correlation between subjects' motor function and their cognitive abilities, mood, and sleep was subsequently analyzed.Results:Systolic blood pressure, heart rate, PHQ-9, MMSE, and ESS scores were identified as significant factors influencing TUGT time.Specifically, TUGT time was positively correlated with PHQ-9 and ESS scores, while exhibiting negative correlations with systolic blood pressure, heart rate, and MMSE scores.Additionally, TUGT time was negatively correlated with the MMSE subcomponents of orientation, immediate memory, and verbal ability.All observed differences were statistically significant(all P<0.05).Logistic regression analysis indicated that an increase in the PHQ-9 score was associated with an odds ratio( OR)of 1.099(95% CI: 1.045-1.155, P<0.001)(mild motor abnormality group)and 1.150(95% CI: 1.066-1.242, P<0.001)(Significant motor abnormality group).Additionally, a reduction in the MMSE score was observed, with an OR of 0.939(95% CI: 0.886-0.995, P<0.001)(mild motor abnormality group)and 0.793(95% CI: 0.729-0.862, P<0.001)(Significant motor abnormality group).Furthermore, an increase in the ESS score was noted, with ORs of 1.139(95% CI: 1.094-1.186, P<0.001)(mild motor abnormality group)and 1.203(95% CI: 1.132-1.279, P<0.001)(Significant motor abnormality group).These findings suggest that these variables are independently related to decreased motor function. Conclusions:Depression, cognitive impairment, and excessive daytime sleepiness are independent risk factors for motor dysfunction among elderly individuals in community settings.The Timed Up and Go Test TUGT can be utilized for the early screening of motor function decline in this population.
