ObjectiveTo apply and systematically evaluate the care-need grading assessment tool for adults with disabilities in welfare institutions. MethodsFrom June to July, 2025, four disability care institutions in Shanghai were selected, and a total of 1 002 adults with disabilities were assessed using the self-developed care-need grading assessment tool for adults with disabilities in welfare institutions. The application effectiveness of the tool was evaluated by analyzing the classification results of care need grading and the reclassification in grade distribution. The application validity was assessed through score differences across functional dimensions, reduced-dimension clustering scatter plots for each grade, and external variables. The application efficiency was evaluated based on the average assessment duration and learning curves. The application utility value was assessed through the distribution characteristics and mapping relationships of service lists across different grades. ResultsThe distribution across disability levels was 84 in Level 1, 298 in Level 2, 92 in Level 3, 246 in Level 4, and 282 in Level 5, indicating a trend where individuals from higher levels in the original system shifted toward the middle and lower levels of the new system. The tool demonstrated strong discriminatory power across the four functional dimensions (P < 0.001), indicating favorable discriminant validity. The five classified levels exhibited clear clustering boundaries in the reduced-dimension space, reflecting robust structural validity. The classification results were consistent with theoretical expectations regarding external variables, including age, disability type, disability grade, number of comorbidities, and primary clinical diagnoses (P < 0.05), demonstrating sound external validity. The median assessment duration was 5.80 minutes, with a significant learning effect (P = 0.037), showcasing high efficiency. Finally, service lists tailored to different care levels were developed, where service content exhibited graded differences across care levels and accurately mapped the care-need characteristics of each grade, reflecting substantial utility value. ConclusionThis tool can classify the care needs of adults with disabilities into five levels, with sound validity and high assessment efficiency; while the resulting service lists for different care levels can be used to guide practical implementation, which can be used for the graded assessment of care needs among adults with disabilities.

Objective To develop a tool for assessing the needs for care services for adults with disabilities in welfare institutions,and formulate criteria for classifying care needs.Methods Based on the theory of the International Classification of Functioning,Disability and Health,the core contents of domestic and international care service assessment standards were analysed,and the first draft of the assess-ment tool was formed integrating with the current practice of welfare institutions.A total of eleven experts in the field of care services validated the first draft,and the assessment tool was revised according to the experts'opin-ions.From May to June,2024,340 adults with disabilities from Second Social Welfare Institute of Shanghai were graded to analyze the reliability and validity of the assessment tool.And then,1 046 subjects from Second Social Welfare Institute of Shanghai were graded using the assessment tool,and the scoring intervals for the five levels of care were determined using cluster analysis.Results The assessment tool included four first-level dimensions,eleven second-level dimensions,39 third-level dimen-sions and 43 indicators.The coefficients of variation of each dimension and indicator were less than 0.25 for ex-pert validation,while the average score of the importance of each indicator was above 4.63,with a full score rate more than 0.86.The overall Cronbach's α coefficient was 0.956,the test-retest reliability was 0.997,and the con-tent validity index of each indicator was 0.83 to 1.00.The exploratory factor analysis extracted four common fac-tors,with a cumulative variance contribution of 86.679%;the loading coefficients of indicators were 0.675 to 0.878,and the correlation coefficients among the dimensions were 0.325 to 0.476.Cluster analysis determined the level of institutional care needs as level 1(severe),level 2(medium-heavy),level 3(medium),level 4(light-moderate),and level 5(light).Conclusion The needs assessment tool for care services for adults with disabilities in welfare institutions developed in this study is good in reliability and validity,and can be used in guiding the care services provided for people with disabilities more efficient and targeted.

Objective To explore the application value of serum heat shock protein 90α(Hsp90α)combined with β2-microglobulin(β2-MG)detection in the early diagnosis and prognosis of colorectal cancer(CRC).Methods A total of 101 patients with CRC who received their first treatment were selected as the CRC group(no surgery,radiotherapy or chemotherapy before enrollment),100 patients with benign colon tumor admitted to our hospital during the same period were selected as the benign tumor group and 94 healthy individuals who underwent physical examinations in our hospital were used as the control group.The levels of serum Hsp90α and β2-MG in all subjects were detected by ELISA.Follow-up was conducted every three months within the first two years after surgery,and every six months in the third year,for a total follow-up period of 3 years,and the survival status of CRC patients within 3 years was recorded.ROC curve analysis was used to evaluate the diagnostic value of serum Hsp90α and β2-MG for CRC.The Kaplan-Meier method was used to draw the survival curves of CRC patients with different expression levels of Hsp90α and β2-MG.Results The serum levels of Hsp90α and β2-MG increased successively in the control group,the benign tumor group and the CRC group(P＜0.05).There were no significant differences in serum levels of Hsp90α and β2-MG between CRC patients of different genders,ages and lesion locations.The levels of serum Hsp90α and β2-MG in patients with tumor diameter＞5 cm,low differentiation degree,TNM stage Ⅲ and lymph node metastasis were higher than those in patients with tumor diameter≤5 cm,moderate to high differentiation degree,TNM stage Ⅰ-Ⅱ and no lymph node metastasis(P＜0.05).The ROC results showed that the combined diagnostic efficacy of serum Hsp90α and β2-MG was superior to that of serum Hsp90α or β2-MG alone(Z=2.433,2.435,P＜0.05).Based on the average expression levels of serum Hsp90α and β2-MG in CRC patients(76.66 μg/L and 6.52 μg/L),patients were divided into the high expression group of Hsp90α(59 cases),the low expression group of Hsp90α(42 cases),the high expression group of β2-MG(63 cases)and the low expression group of β2-MG(38 cases).Among the 101 CRC patients,31 died and 70 survived,with a total survival rate of 69.31％.The Kaplan-Meier survival curve showed that the 3-year survival rates of patients with high expression levels of Hsp90α and β2-MG were lower than theose of patients with low expression levels of Hsp90α and β2-MG(P＜0.01).Conclusion The expression levels of serum Hsp90α and β2-MG are both elevated in CRC patients,and they are closely related to the occurrence,development and prognosis of CRC.

Advanced atherosclerosis is the major global cause of death, as featured by the aggregation of apoptotic cells (ACs) in necrotic cores. The defective efferocytosis and dysfunctional cholesterol efflux of macrophages are the main reasons for forming necrotic cores in advanced atherosclerosis. In this study, we constructed self-assembled procyanidins (PC) NPs for loading pitavastatin (Pita). The designed HA@PC@Pita NPs with hyaluronic acid (HA) modification combined the advantages of efferocytosis restoration of Pita and cholesterol efflux enhancement of PC. In vitro assay indicated that HA@PC@Pita NPs could induce M1/M2 repolarization and upregulate ERK5/Mertk expression to restore efferocytosis of macrophages. Simultaneously, HA@PC@Pita NPs notably promoted cholesterol efflux by promoting macrophage lipophagy, a selective autophagy of lipid droplets. In vivo study showed that HA@PC@Pita NPs cleared necrotic core and enhanced plaque stability in the ApoE ^-/- mice model with advanced atherosclerosis. Taken together, this study demonstrated the potential of HA@PC@Pita NPs for the treatment of advanced atherosclerosis.

Cognitive dysfunction refers to dysfunction of individual perception,memory,understanding,learning,creation and other dysfunctions caused by abnormal brain function and structure.Based on the fact that the spleen can't regulate transportation and transformation,govern blood and send up essential substance,combined with the microbiota-gut-brain axis,this article discussed the etiology and pathogenesis of intestinal flora imbalance affecting cognitive dysfunction in TCM.It was proposed that the spleen in TCM and intestinal flora are connected in physiology and pathology:the spleen regulates spirit and governs cognition,when the spleen fails to function normally that it can't dominate transportation and transformation,govern blood and send up essential substance will cause that the brain spirit can not be nourished;intestinal flora is closely related to the spleen in TCM,and affects brain function through the nervous system,endocrine,immune and metabolic mechanisms.This article can provide explore new ideas for the clinical research and treatment of cognitive dysfunction of traditional Chinese and Western medicine.

The consumption of a high-fat diet(HFD)has been linked to osteoporosis and an increased risk of fragility fractures.However,the specific mechanisms of HFD-induced osteoporosis are not fully understood.Our study shows that exposure to an HFD induces premature senescence in bone marrow mesenchymal stem cells(BMSCs),diminishing their proliferation and osteogenic capability,and thereby contributes to osteoporosis.Transcriptomic and chromatin accessibility analyses revealed the decreased chromatin accessibility of vitamin D receptor(VDR)-binding sequences and decreased VDR signaling in BMSCs from HFD-fed mice,suggesting that VDR is a key regulator of BMSC senescence.Notably,the administration of a VDR activator to HFD-fed mice rescued BMSC senescence and significantly improved osteogenesis,bone mass,and other bone parameters.Mechanistically,VDR activation reduced BMSC senescence by decreasing intracellular reactive oxygen species(ROS)levels and preserving mitochondrial function.Our findings not only elucidate the mechanisms by which an HFD induces BMSC senescence and associated osteoporosis but also offer new insights into treating HFD-induced osteoporosis by targeting the VDR-superoxide dismutase 2(SOD2)-ROS axis.

Objective:To explore the relationship between serum C-X-C motif chemokine ligand 16 (CXCL16) and thioredoxin 80 (Trx80) in patients with Alzheimer′s disease (AD) and cognitive function and prognosis.Methods:A total of 189 AD patients admitted to the Zhangjiakou First Hospital from January 2020 to August 2021 were selected as the AD group, and 110 healthy volunteers who underwent physical examinations in our hospital during the same period were selected as the control group. The serum levels of CXCL16 and Trx80 were detected using enzyme-linked immunosorbent assay (ELISA), and cognitive function was evaluated using the Mini Mental State Examination (MMSE) score. The Spearman correlation method was used to analyze the correlation between serum CXCL16, Trx80 levels and MMSE scores in AD patients. 189 AD patients were divided into poor prognosis group and good prognosis group based on their prognosis. Univariate and multivariate logistic regression methods were used to analyze the influencing factors of poor prognosis in AD patients. Receiver operating characteristic (ROC) curves were used to analyze the predictive value of serum CXCL16 and Trx80 levels for poor prognosis in AD patients.Results:Compared with the control group, the AD group had higher serum levels of CXCL16 and Trx80, and lower MMSE scores (all P<0.05). Spearman correlation analysis showed that the serum levels of CXCL16 and Trx80 in AD patients were negatively correlated with MMSE scores (all P<0.05). After a one-year follow-up, the poor prognosis rate of 189 AD patients was 32.80%(62/189). Univariate analysis showed that age, disease duration, β-amyloid protein (Aβ) 1-40, Aβ 1-42, MMSE score, CXCL16, and Trx80 are associated with poor prognosis in AD patients (all P<0.05). Multivariate logistic regression analysis showed that age, prolonged disease course, and elevated levels of CXCL16 and Trx80 were risk factors for poor prognosis in AD patients (all P<0.05), while an increase in MMSE score was a protective factor ( P<0.05). ROC curve analysis showed that the area under the curve (AUC) of MMSE score, CXCL16, Trx80, CXCL16+ Trx80 combination, and MMSE score+ CXCL16+ Trx80 combination predicting poor prognosis in AD patients were 0.750, 0.763, 0.771, 0.851, and 0.896, respectively. The AUC of the three combination predicting poor prognosis in AD patients was the highest. Conclusions:Elevated serum levels of CXCL16 and Trx80 in AD patients are associated with decreased cognitive function and poor prognosis, and may become auxiliary predictive indicators for poor prognosis in AD patients.
