ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus（WAOF） and cultivated Alpiniae Oxyphyllae Fructus（CAOF） through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF， followed by microscopic identification， thin-layer chromatography（TLC） identification， moisture content（toluene method）， total ash， acid-insoluble ash， water-soluble and alcohol-soluble extracts（hot dipping method）， water-soluble protein， total polysaccharides and total flavonoids（ultraviolet spectrophotometry）， and volatile oil content（method A under general rule 2204）. The contents of five active components（protocatechuic acid， chrysin， kaempferol， tectochrysin and nootkatone） were quantified using ultra-performance liquid chromatography（UPLC）， and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF， quantitative measurements were conducted on its appearance traits including diameter， length， plumpness（diameter/length ratio）， and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation， TLC identification， moisture content， protocatechuic acid content， kaempferol content， odor， or antioxidant activity measured by 2，2ʹ-azino-bis（3-ethylbenzothiazoline-6-sulfonic acid）（ABTS） method. WAOF exhibited significantly higher levels in water-soluble extracts， alcohol-soluble extracts， total polysaccharide content， water-soluble protein content， 100-grain weight， length， and total color difference（ΔE^*ab） compared to CAOF（P<0.01）. In contrast， CAOF showed significantly higher levels of total ash， acid-insoluble ash， content of total flavonoids， volatile oil content， chrysin content， tectochrysin content， nootkatone content， diameter， plumpness， lightness（L^*）， red-green chromaticity（a^*）， yellow-blue chromaticity（b^*）， and antioxidant activity measured by 1，1-diphenyl-2-picrylhydrazyl（DPPH） method compared to WAOF（P<0.01）. Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits， plumpness， L^*， a^*， and b^* exerted significant influence on intrinsic quality. Among the quality traits， total flavonoids， volatile oils， nootkatone， chrysin， and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness， L^*， a^*， and b^* of AOF significantly influence its intrinsic quality， and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

Objective:To investigate the anticipatory grief and to explore its correlates among family caregiv-ers of patients with advanced gastrointestinal cancer.Methods:A total of 283 family caregivers of patients with ad-vanced digestive cancer in the gastroenterology ward of a hospital were assessed using the Perceptive Social Support Scale(PSSS),Simplified Coping Style Questionnaire(SCSQ),Mishel Illness Uncertainty Scale for Family Member(MULS-FM)and Anticipatory Grief Scale(AGS).Results:The median AGS score was 91.00(80.00,98.00).Multiple linear regression analysis revealed that the AGS scores were negatively correlated with PSSS scores(β=-0.21),positive coping scores(β=-0.43),education level(β=-4.99)and age(β=-4.23),but positively correlated with MULS-FM scores(β=0.24).Conclusion:Family caregivers exhibited moderate-to-high anticipato-ry grief,which significantly influenced by age,perceived social support,positive coping style,illness uncertainty and education level.

Three integration results were comprehensively obtained, namely, individuals and families were troubled by multiple problems, there was a strong demand for role support during the transition period, and positive coping led to role growth.Conclusions:Caregivers of patients with young-onset dementia have multiple problems and diverse care needs during the role transition period, and positive coping in this process can lead to role growth.

Chronic diseases in the elderly are characterised by high incidence rates and prolonged duration.Regular participation in multi-component exercise programs promotes both the physical and mental health of the elderly with chronic diseases and reduces the risk of morbidity,making it the key to prevent chronic diseases in the elderly.This review introduces the concepts of multi-component exercise,elucidates the mechanism in improvement of physical and cognitive functions and evaluates the applications as well as the advantages and disadvantages in the management of chronic diseases in the elderly.This review intends to provide references for clinicians who undertake management role of the chronic diseases in elderly populations.

Objective:To systematically evaluate qualitative research on intimate relationship experiences between dementia patients and their spouses.Methods:Qualitative studies on intimate relationship experiences of individuals with dementia and their spouses were electronically retrieved from the Cochrane Library, PubMed, Web of Science, Embase, China National Knowledge Infrastructure, WanFang Data, VIP, and SinoMed. The search period was from the establishment of the database to June 30, 2025. The literature was evaluated for quality using the Joanna Briggs Institute Quality Assessment Criteria for Qualitative Research. The results were synthesized through the aggregative integration method.Results:A total of 12 studies were included, yielding 46 findings that were categorized into 9 themes and synthesized into 3 integrated outcomes of dysfunction and challenges in intimate relationships, adjustment and coping strategies in intimate relationships, and reshaping and sublimation in intimate relationships.Conclusions:Patients with dementia and their spouses face multiple challenges in their intimate relationships and marital quality. Healthcare providers should focus on the lived experiences and unmet needs of dementia patients and their spouses, offer targeted psychological interventions and support, promote the stable development of intimate relationships, so as to improve their capacity to cope with the disease.

Background::Pulmonary embolism (PE) is a severe and acute cardiovascular syndrome with high mortality among patients with autoimmune inflammatory rheumatic diseases (AIIRDs). Accurate prediction and timely intervention play a pivotal role in enhancing survival rates. However, there is a notable scarcity of practical early prediction and risk assessment systems of PE in patients with AIIRD.Methods::In the training cohort, 60 AIIRD with PE cases and 180 age-, gender-, and disease-matched AIIRD non-PE cases were identified from 7254 AIIRD cases in Tongji Hospital from 2014 to 2022. Univariable logistic regression (LR) and least absolute shrinkage and selection operator (LASSO) were used to select the clinical features for further training with machine learning (ML) methods, including random forest (RF), support vector machines (SVM), neural network (NN), logistic regression (LR), gradient boosted decision tree (GBDT), classification and regression trees (CART), and C5.0 models. The performances of these models were subsequently validated using a multicenter validation cohort.Results::In the training cohort, 24 and 13 clinical features were selected by univariable LR and LASSO strategies, respectively. The five ML models (RF, SVM, NN, LR, and GBDT) showed promising performances, with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.962-1.000 in the training cohort and 0.969-0.999 in the validation cohort. CART and C5.0 models achieved AUCs of 0.850 and 0.932, respectively, in the training cohort. Using D-dimer as a pre-screening index, the refined C5.0 model achieved an AUC exceeding 0.948 in the training cohort and an AUC above 0.925 in the validation cohort. These results markedly outperformed the use of D-dimer levels alone.Conclusion::ML-based models are proven to be precise for predicting the onset of PE in patients with AIIRD exhibiting clinical suspicion of PE.Trial Registration::Chictr.org.cn: ChiCTR2200059599.
