Objective To investigate the public health issues associated with the follow-up outcomes of mental health in elderly community residents with a focus on mild cognitive impairment （MCI） and emotional problems （anxiety and depression）， as the burden of various diseases increases with global population growth and aging. Methods In this study， Patient Health Questionnaire-9， Early Dementia Screening Scale， Montreal Cognitive Assessment， Generalized Anxiety Disorder Scale， Geriatric Depression Scale， and Activities of Daily Living scale were used to analyze the data on MCI and emotional problems among the elderly in a district of Shanghai， China. The t-test， Spearman correlation analysis， and linear regression analysis were used to identify related protective factors and evaluate the effectiveness of comprehensive intervention measures. Results The first session of intervention led to an improvement in cognitive impairment （P<0.001）. During the first session of intervention， exercise and skill training were very effective in improving cognitive impairment （r=0.71 and 0.68， P<0.001）， while group instruction and the distribution of educational materials failed to achieve an ideal effectiveness. The second session of intervention also had a significant effect on cognitive impairment （P<0.05）； however， the second session of intervention lacked a significant overall effect， and skill training remained the most effective intervention method （Pr=0.0344， P<0.05）. The research findings showed that the two sessions of community intervention were protective factors against MCI and depression， while they could not alleviate anxiety. Conclusion This study validates the effectiveness of follow-up intervention measures in improving cognitive function in elderly patients with MCI， which provide scientific prediction and reference for early screening， prediction， and follow-up intervention of elderly dementia and MCI at the community level.

ObjectiveTo evaluate the methodological quality and reporting quality of published guidelines/consensuses on traditional Chinese medicine （TCM）/integrated traditional Chinese and Western medicine diagnosis and treatment of nonalcoholic fatty liver disease （NAFLD）， and to provide a basis for formulating guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD in the future. MethodsDatabases including PubMed， Embase， Web of Science， CNKI， Wanfang Data， and CBM and the websites of China Association of Chinese Medicine and China Association of Integrative Medicine were searched for related articles published up to September 1， 2024. Two clinical researchers independently assessed the methodological quality and reporting quality of the guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD by using Appraisal of Guidelines for Research and Evaluation Ⅱ （AGREE Ⅱ） and Reporting Items for Practice Guidelines in Healthcare （RIGHT）. ResultsA total of nine guidelines/consensuses were included after literature screening， with four guidelines and five expert consensuses. The scores of different domains assessed by AGREE Ⅱ for the nine guidelines/consensuses were as follows： scope and purpose （47.1%）， stakeholder involvement （41.0%）， rigor of development （21.6%）， clarity of presentation （40.2%）， applicability （19.0%）， and editorial independence （19.6%）. The recommendation level of the articles was B level （recommended after revision） for four articles and C level （not recommended） for five articles. The RIGHT assessment showed high reporting rates for “Basic Information” and “Background”， while other areas needed to be improved. Currently， there was no international standard for the guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD， and the quality of these guidelines/consensuses needed to be enhanced to ensure comprehensiveness and credibility. ConclusionThere is still potential for improving the quality of guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD， and AGREE Ⅱ and RIGHT checklists should be strictly followed to ensure the fairness， scientific rigor， and transparency of these guidelines/consensuses.

Objective:To predict the short-term postoperative recurrence status of patients with refractory temporal lobe epilepsy (TLE) by analyzing preoperative 18F-FDG PET images and patients′ clinical characteristics based on deep residual neural network (ResNet). Methods:Retrospective analysis was conducted on preoperative 18F-FDG PET images and clinical data of 220 patients with refractory TLE (132 males and 88 females, age 23.0(20.0, 30.2) years)) in the First Affiliated Hospital of Jinan University between January 2014 and June 2020. ResNet was used to perform high-throughput feature extraction on preprocessed PET images and clinical features, and to perform a postoperative recurrence prediction task for differentiating patients with TLE. The predictive performance of ResNet model was evaluated by ROC curve analysis, and the AUC was compared with that of classical Cox proportional risk model using Delong test. Results:Based on PET images combined with clinical feature training, AUCs of the ResNet in predicting 12-, 24-, and 36-month postoperative recurrence were 0.895±0.073, 0.861±0.058 and 0.754±0.111, respectively, which were 0.717±0.093, 0.697±0.081 and 0.645±0.087 for Cox proportional hazards model respectively ( z values: -3.00, -2.98, -1.09, P values: 0.011, 0.018, 0.310). The ResNet showed best predictive effect for recurrence events within 12 months after surgery. Conclusion:The ResNet model is expected to be used in clinical practice for postoperative follow-up of patients with TLE, helping for risk stratification and individualized management of postoperative patients.

Purpose To investigate the characteristics of 18F-Florbetaben(18F-FBB)β-amyloid(Aβ)PET imaging in different brain regions of Alzheimer's disease(AD)patients with different degrees of cognitive impairment,and to explore the correlation between Aβ deposition and cognitive dysfunction.Materials and Methods A total of eighteen patients with a clinical diagnosis of probable AD from August 2022 to October 2023 were retrospectively included in Huashan Hospital.All patients had Aβ abnormal deposition in the brain as confirmed by 18F-FBB PET imaging.According to the severity of symptoms,they were divided into the AD-induced mild cognitive impairment(MCI)group(8 cases)and the dementia group(10 cases).In addition,12 healthy controls were included.First,the standardized uptake value ratio of abnormal Aβ deposition in the frontal lobe,lateral parietal lobe,lateral temporal lobe,anterior and posterior cingulate gyrus,and compound cortex was semi-quantitatively calculated and compared among the three groups based on the subjects'brain MRI and automated anatomical labeling template.The correlation between the degree of Aβ deposition in the brains of AD patients and cognitive scale scores(mini-mental state examination,Montreal cognitive assessment)was then further analyzed.Results The standardized uptake value ratio values of Aβabnormal deposition in the frontal lobe,lateral temporal lobe,lateral parietal lobe,anterior and posterior cingulate cortex and compound cortex in the AD-induced MCI and dementia groups were significantly higher than those in the healthy controls(t=7.442-9.151,all P＜0.05).However,there was no significant difference in the standardized uptake value ratio values of Aβ abnormal deposition in the above brain regions between the MCI and dementia groups(t=0.312-0.996,all P＞0.05).In addition,there was no significant correlation between the degree of Aβ deposition in the brain and the cognitive scale scores(mini-mental state examination,Montreal cognitive assessment)in the AD-induced MCI and dementia groups(r=-0.049-0.050,all P＞0.05).Conclusion Aβ deposition in the brains of AD-induced MCI and dementia is significantly higher than in the healthy controls.However,Aβ deposition cannot identify AD patients with different degrees of cognitive impairment,reflecting that Aβ deposition has certain limitations in assessing the severity of clinical symptoms of AD.

Objective To systematically analyze the effect of rhythmic physical activity on executive function and sub-components in healthy preschool children. Methods Literature in Chinese and English was retrieved from databases such as CNKI,Wanfang Data,EBSCO,PubMed,Google Scholar and Web of Science for researches about the intervention of rhythmic physical activity for executive function of healthy children aged three to six years,up to October,2024.The methodological quali-ty of the researches was evaluated with PEDro Scale,and data were extracted for a systematic review. Results Ten researches,published between 2019 and 2024,from seven countries,were included;and seven were random-ized controlled trials and three were quasi experiment,involving a total of 1 047 children.The scores of the PE-Dro scale ranged five to eight.The rhythmic physical activity intervention was 20 to 50 minutes a time,one to five times a week,for six to 20 weeks.The forms of rhythmic physical activity intervention included sports activi-ties(street dance,flower ball cheerleading,walking,running,jumping and other motor skill exercises),music teaching activities(music perception,rhythm synchronization and music games),dance activities(creative dance,action imitation and role playing)and music performance activities(body percussion,rhythm sticks,sand balls and drums).Rhythmic physical activity was effective on at least one sub-component of executive function.How-ever,five of the seven researches involving cognitive flexibility failed to demonstrate a positive effect.Six re-searches compared the effects of rhythmic physical activity versus other physical activities,and five found that rhythmic physical activity was more effective on executive function. Conclusion Rhythmic physical activity can improve inhibitory control and working memory in preschool children;but the effect on cognitive flexibility remain controversial.

ObjectiveTo explore the effect of home exercise on pain, function and quality of life after operation for rotator cuff injury. MethodsFrom June, 2023 to June, 2024, 45 patients after operation for rotator cuff injury were selected from Xuzhou Rehabilitation Hospital Affiliated to Xuzhou Medical University and Xuzhou Central Hospital, and randomly divided into conventional group (n = 15), home-based group (n = 15) and combined group (n = 15). The conventional group received an eight-week routine rehabilitation program in hospital, the home-based group received an eight-week home exercise prescription training, and the combined group first received four weeks of routine rehabilitation in hospital, and followed by four weeks of home exercise prescription training. They were assessed with Visual Analogue Scale for pain (VAS), University of California at Los Angeles shoulder rating scale (UCLA), Constant-Murley Score (CMS), range of motion (ROM) of shoulder, and the Short-form of Health Survey-36 (SF-36) before treatment, and four and eight weeks after treatment. ResultsVAS scores decreased in all the three groups four and eight weeks after treatment (Z > 2.964, P < 0.001), which was the most in the home-based group four weeks after treatment (|Z| > 2.531, P < 0.05). The main effect of time was significant in scores of UCLA, CMS, and physical health and mental health of SF-36 (F > 498.102, P < 0.001), which improved after treatment (P < 0.001). The main effect of group was significant in score of mental health of SF-36 (F = 7.408, P = 0.002), which was the most in the home-based group four and eight weeks after treatment (P < 0.01). The interaction was significant in score of physical health of SF-36 (F = 10.138, P < 0.001), which was the least in the home-based group four weeks after treatment (P < 0.05). The main effect of time was significant in every direction of ROM, which improved after treatment (P < 0.001). The interaction was significant in ROM of abduction and external rotation (F > 4.059, P < 0.01), and almost significant in ROM of flexion (F = 2.412, P = 0.055). However, ROM of flexion was less in the home-based group than in the combined group four weeks after treatment (P = 0.047), which was less in the home-based group than in the conventional group eight weeks after treatment (P = 0.042); ROM of abduction was the least in the home-based group four weeks after treatment (P < 0.01), which was less in the home-based group than in the combined group eight weeks after treatment (P = 0.046); ROM of external rotation was less in the home-based group than in the combined group four weeks after treatment (P = 0.022). ConclusionHome exercise is effective on pain, function and quality of life in patients after operation for rotator cuff injury. There are benefits with both home exercise and institution-based rehabilitation, and almost the same in a whole eight weeks after treatment.

Background With the increasing exposure to hazardous chemicals in the workplace and frequency of occupational injuries and occupational safety accidents, the acquisition of occupational exposure limits of hazardous chemicals is imminent. Objective To obtain more unknown immediately dangerous to life or health (IDLH) concentrations of hazardous chemicals in the workplace by exploring the application of quantitative structure-activity relationship (QSAR) prediction method to IDLH concentrations, and to provide a theoretical basis and technical support for the assessment and prevention of occupational injuries. Methods QSAR was used to correlate the IDLH values of 50 benzene and its derivatives with the molecular structures of target compounds. Firstly, affinity propagation algorithm was applied to cluster sample sets. Secondly, Dragon 2.1 software was used to calculate and pre-screen 537 molecular descriptors. Thirdly, the genetic algorithm was used to select six characteristic molecular descriptors as dependent variables and to construct a multiple linear regression model (MLR) and two nonlinear models using support vector machine (SVM) and artificial neural network (ANN) respectively. Finally, model performance was evaluated by internal and external validation and Williams diagram was drawn to determine the scopes of selected models. Results The ANN model results showed that \begin{document}$ {R}_{\mathrm{t}\mathrm{r}\mathrm{a}\mathrm{i}\mathrm{n}}^{2} $\end{document}=0.8526 and \begin{document}$ {R}_{\mathrm{t}\mathrm{e}\mathrm{s}\mathrm{t}}^{2} $\end{document}=0.8505 respectively, root mean square (RMSE) error=0.5243, mean absolute error (MAE)=0.4610, internal and external validation coefficients \begin{document}$ {Q}_{\mathrm{l}00}^{2} $\end{document}=0.8476 and \begin{document}$ {Q}_{\mathrm{e}\mathrm{x}\mathrm{t}}^{2} $\end{document}=0.8905 respectively. By comparison, the performance verification parameters of the ANN model were superior to the MLR and SVM models, and all substances were in the applicable domain. Conclusion At present, the ANN model has the best performance in fitting ability, stability, and prediction, and is suitable for predicting IDLH concentrations of benzene and its derivatives. Predicting the IDLH concentraitons of benzene and its derivatives by QSAR method is an effective method, and provides a theoretical basis and technical support for the development of occupational health and safety.

Objective:To explore the effects of mechanical factors on the morphology of the growth plate and proximal femur development, in order to provide a mechanical basis for the mechanism of Cam lesions in femoral acetabular impingement (FAI).Methods:Using CT scan data of hip joint from adolescents, we constructed three-dimensional finite element models of normal and extended proximal femoral epiphyseal growth plates. Dynamic mechanics and position data from daily activities (walk, stand on one and two feet, go upstairs and downstairs, sit and stand up, squat and stand up) and basketball layup drills were collected from five healthy volunteers using the Vicon system. The mean values of femoral head mechanical loads and positions at peak values, movement onset, and termination were selected for finite element analysis to observe the distribution of equivalent stress, normal stress, and shear stress on the two growth plate models under different activity modes.Results:Successful construction of three-dimensional finite element models for normal and extended proximal femoral epiphyseal growth plates was achieved. Mechanical load values and spatial positions of the femoral head during daily activities and layup movements were obtained. In daily activities, peak equivalent stress values for normal and extended growth plates ranged from 1.6 to 11.0 MPa; compressive stress ranged from 1.7 to 12.0 MPa; tensile stress ranged from 0.5 to 10.0 MPa; and shear force ranged from 0.4 to 7.1 MPa. The compressive stress during walking, standing on one or both feet, going up and down stairs, sitting and standing, and squatting was concentrated in the central and lateral areas; tensile stress was concentrated in the central and medial areas; shear force was concentrated in the medial area and the anterior and posterior edges of the growth plate. During a layup, the compressive stress in the center, outer upper side, and medial edge of the growth plate of the normal model was notably concentrated, with peaks fluctuating between 5.5-19.0 MPa, 5.7-11.0 MPa, and 5.4-7.3 MPa respectively; tensile stress and shear force were concentrated at the inner and outer edges as well as in the central area, with peaks fluctuating between 3.0-24.0 MPa and 3.0-26.0 MPa respectively, these values were significantly different from those observed during daily activities. For the elongated growth plate, compressive stress was concentrated at the central and lateral edges with peaks fluctuating between 17.0-41.0 MPa and 17.0-38.0 MPa respectively; simulated shear stress and tensile stress showed significant concentration at peaks fluctuating between 4.9-34.0 MPa, also significantly different from those observed during daily activities.Conclusion:The difference in mechanical distribution between daily activities, basketball layup training, as well as between normal and extended growth plates may be the mechanical initiating factor in the development of extended growth plates and the formation of Cam lesions, it may be the mechanical initiating factor for the development of extended growth plates and the collision of Cam lesions in FAI.
