Aim To explore the mechanism of Lycium barbarum glycopeptide(LbGP)improving aging in rat primary ovarian granulosa cells.Methods This study divided the cells into a normal group,a DOX group,and four different LbGP concentration treatment groups post-DOX intervention.Results Cell proliferation was assessed using CCK-8,EDU,and Ki67 assays,while aging markers and mitochondrial function-related fac-tors were detected using immunofluorescence and West-ern blotting.The results showed that,compared to the DOX group,LbGP treatment significantly increased cell viability(P＜0.05)and promoted proliferation(P＜0.05).Post LbGP treatment,the β-galactosidase-posi-tive area in cells was significantly reduced compared to the DOX group(P＜0.05).Immunofluorescence re-sults indicated that,compared to the DOX group,levels of p21 and γH2AX significantly decreased(P＜0.05),while pRB increased(P＜0.05)after LbGP treatment.Western blot results showed that,compared to the DOX group,the aging phenotype proteins p21 and p53 significantly decreased(P＜0.05),and pRB notably increased(P＜0.05)in the LbGP treatment group.The release of cytC into the cytoplasm and the activated caspase-9 significantly decreased(P＜0.05);levels of CAMKK2,pAMPK,and mitochondrial calcium homeostasis regulator MCU increased(P＜0.05);nuclear energy metabolism-related proteins SirT1,PGC1α/β and ATP5A1 significantly increased(P＜0.05);compared to the DOX group,ROS levels significantly decreased after LbGP treatment(P＜0.05).Conclusions The results suggest that LbGP can ameliorate DOX-induced aging in rat primary ovar-ian granulosa cells,potentially through the upregulation of the CAMKKβ/AMPK signaling pathway,thereby im-proving mitochondrial calcium homeostasis and increas-ing the expression levels of cell energy metabolism-re-lated regulatory proteins.This provides an experimen-tal basis for LbGP's potential role in supporting the im-provement of ovarian function.

Objective:To explore the influence of cardiac rehabilitation therapy on the postoperative quality of life, cardiac function and prognosis of patients undergoing transcatheter aortic value replacement (TAVR).Methods:A total of 182 patients with aortic valve stenosis who underwent TAVR in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2021 to May 2023 were selected as the research subjects. The patients were divided into the observation group and the control group by the random number table method, with 91 cases in each group. The control group was given conventional drug treatment after the operation, while the observation group was given conventional drug treatment + cardiac rehabilitation treatment after the operation. The baseline clinical data, quality of life before and after intervention (Minnesota Quality of Life Scale score), cardiac function [6-minute walking distance (6MWT), B-type brain natriuretic peptide (BNP)] of the two groups of patients were compared. The left ventricular ejection fraction (LVEF), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), and the incidence of adverse events one year after TAVR were evaluated using the Cox regression model to assess the effect of cardiac rehabilitation therapy on the occurrence of adverse events one year after TAVR. Kaplan-Meier survival analysis was used to compare the cumulative rate of no adverse events one year after TAVR in the two groups of patients.Results:After the intervention in both groups, the Minnesota Quality of Life Scale score, 6MWT, BNP, and LVEF were significantly improved compared with those before the intervention (all P<0.05), and the Minnesota Quality of Life Scale score, 6MWT, BNP, and LVEF in the observation group after the intervention were better than those in the control group (all P<0.05). The incidences of stroke and heart failure in the observation group one year after TAVR were significantly lower than those in the control group (all P<0.05). Cox regression analysis showed that cardiac rehabilitation significantly reduced the risk of adverse events one year after TAVR in patients ( HR: 0.72; 95% CI: 0.46-0.97; P=0.035). Kaplan-Meier survival analysis showed that the cumulative rate of no adverse events at 3, 6, and 12 months after TAVR in the observation group was significantly higher than that in the control group (94.3%, 89.5%, 76.8% vs 83.4%, 74.6%, 57.8%, all P<0.05). Conclusions:Cardiac rehabilitation therapy can significantly improve the postoperative quality of life and cardiac function of patients with TAVR, bringing obvious survival benefits to such patients.

Objective To rexplore the content structure characteristics and psychometric properties of assessment scales for funda-mental movement skills(FMS)in school-aged children,based on International Classification of Functioning,Dis-ability and Health-Children and Youth Version(ICF-CY)framework.Methods Literatures on assessment scales for FMS in school-aged children were retrieved from PubMed,Science Di-rect,Web of Science,EMBase,PsycINFO,CNKI and Wanfang data from inception to July,2025.The contents of the included scales were analyzed using the ICF-CY linking rule.The COSMIN RoB tool was used to assess the psychometric properties of the scales,and the GRADE system was applied to evaluate the overall quality of evi-dence.Results A total of 29 studies were included,involving six assessment scales:Bruininks-Oseretsky Test of Motor Profi-ciency-2(BOT-2),Canadian Assessment of Movement Skill and Agility(CAMSA),K?rperkoordinationstest für Kinder(KTK),Movement Assessment Battery for Children-2(MABC-2),Motorische Basiskompetenzen test Battery(MOBAK),and Test of Gross Motor Development-3(TGMD-3).In the ICF-CY linking analysis,all six tools addressed joint mobility functions(b710)and joint stability functions(b715),while five of them also in-volved hand and arm use(d445).The number of linked items ranged from 5 to 11.BOT-2 and TGMD-3 linked to 11 items,showing broad coverage;BOT-2 focused more on the body function dimension,whereas TGMD-3 em-phasized activity and participation dimensions,especially the performance of hand function in daily activities.In bias risk assessment,TGMD-3 showed the lowest risk(50%rated A and 50%rated B),while MABC-2 had the highest proportion of C ratings(55.6%),followed by BOT-2(33.3%).In evidence grading,TGMD-3 was rated high quality,KTK moderate,BOT-2 and CAMSA low,and MABC-2 and MOBAK very low.Conclusion TGMD-3 is recommended as the primary tool for assessing FMS in school-aged children for broad coverage of ICF-CY items,strong psychometric properties and high evidence quality.KTK,with moderate evidence quali-ty,may serve as a secondary option,but should be used cautiously in China.Although CAMSA is easy to admin-ister,its validity and reliability are low,so it is only suitable for rapid classroom screening.BOT-2,despite cover-ing more ICF-CY items,has a higher bias risk and low evidence quality.MOBAK and MABC-2 have very low evidence quality and are not recommended for current use.

Objective To explore the types of symptom clusters in patients with bladder instillation and identify the core symptoms through symptom network analysis,and to provide evidence for symptom management of the patients.Methods Convenience sampling was used to select 226 patients with bladder instillation for bladder cancer at a Tier-IIIA hospital in Guiyang from March 2023 to July 2024.Data were collected through review of medical record,general information questionnaires and symptom assessment questionnaires specific to the patients with bladder instillation.Exploratory factor analysis was used to extract symptom clusters,and symptom relationships were analysed using R language for network layout and centrality calculations.Results A total of 223 patients with bladder cancer completed the survey.Four symptom clusters were identified,namely the urinary system symptom cluster,digestive system symptom cluster,somatic symptom cluster and psychological symptom cluster,with a cumulative variance contribution rate of 66.038%.The symptom network analysis showed strong associations between dysuria and urethral pain during catheterisation,incomplete emptying and dysuria,as well as distress and poor sleep quality.In terms of centrality indicators,the top three symptoms by strength were dysuria(rS=2.26),incomplete emptying(rS=0.99)and poor sleep quality(rS=0.90).Of the expected impacts,the top three were dysuria(rE=2.09),poor sleep quality(rE=1.34)and frequency of urinary(rE=0.55).Regarding the closeness centrality,the top three were dysuria(rC=2.23),incomplete emptying(rC=0.64)and poor sleep quality(rC=0.54).Dysuria had the highest strength,expected impact and closeness centrality,indicating the dysuria was the core symptom in the patients with bladder cancer.Conclusion For the patients with bladder instillation experience,multiple and interconnected symptoms appear at the same time and together they form a symptom clusters,of which the pain in urination is the core symptom.Medical staff should consider symptom prevalence and core symptoms and to develop the targeted and precise management strategies for targeted nursing.

Purpose: Biomarkers predicting clinically significant prostate cancer (sPC) before biopsy are currently lacking. This study aimed to develop a non-invasive urine test to predict sPC in at-risk men using urinary metabolomic profiles. Materials and Methods: Urine samples from 934 at-risk subjects and 268 treatment-naïve PC patients were subjected to liquid chromatography/mass spectrophotometry (LC-MS)-based metabolomics profiling using both C18 and hydrophilic interaction liquid chromatography (HILIC) column analyses. Four models were constructed (training cohort [n=647]) and validated (validation cohort [n=344]) for different purposes. Model I differentiates PC from benign cases. Models II, III, and a Gleason score model (model GS) predict sPC that is defined as National Comprehensive Cancer Network (NCCN)-categorized favorable-intermediate risk group or higher (Model II), unfavorable-intermediate risk group or higher (Model III), and GS ≥7 PC (model GS), respectively. The metabolomic panels and predicting models were constructed using logistic regression and Akaike information criterion. Results: The best metabolomic panels from the HILIC column include 25, 27, 28 and 26 metabolites in Models I, II, III, and GS, respectively, with area under the curve (AUC) values ranging between 0.82 and 0.91 in the training cohort and between 0.77 and 0.86 in the validation cohort. The combination of the metabolomic panels and five baseline clinical factors that include serum prostate-specific antigen, age, family history of PC, previously negative biopsy, and abnormal digital rectal examination results significantly increased AUCs (range 0.88–0.91). At 90% sensitivity (validation cohort), 33%, 34%, 41%, and 36% of unnecessary biopsies were avoided in Models I, II, III, and GS, respectively. The above results were successfully validated using LC-MS with the C18 column. Conclusions Urinary metabolomic profiles with baseline clinical factors may accurately predict sPC in men with elevated risk before biopsy.
