Objective To explore the characteristics and temporal trends of renal cancer burden among Chinese adolescents and young adults(AYA), and predict its future epidemic situation, so as to provide evidence for formulating public health policies and reducing the disease burden.Methods Epidemiological data of renal cancer in Chinese AYA(15-39 years)from 1990 to 2021 were obtained from the Global Burden of Disease(GBD)2021 database. The current status and trends of renal cancer in this population were analyzed. The incidence and mortality trends of renal cancer in AYA over the next 15 years was predicted with ARIMA model. The impacts of smoking and body mass index(BMI)on the disease burden were evaluated. Results In 2021, the incidence(1.12/100000), prevalence(8.61/100000), mortality(0.19/100000), and disability-adjusted life years(DALYs)(11.37/100000 person-years)of renal cancer in Chinese AYA were significantly higher than those in 1990 and above the global average. All burden indicators and their increases were higher in males than in females, and the burden accelerated after 30 years of age. The incidence rose steadily from 2003 to 2021(APC=3.95), while the mortality increased significantly from 2013 to 2021(APC=2.40). The burden attributed to high BMI continued to rise, and the smoking-attributable fraction in males first increased then decreased. ARIMA predicted that the incidence of renal cancer in Chinese AYA males would accelerate, while the mortality in both genders would stabilize. Conclusion The burden of renal cancer in Chinese AYA shows a significant upward trend. Males and people over 30 years old are key targets for prevention and control. Strengthening the management of risk factors(smoking, high BMI)and promoting early diagnosis and treatment are essential to reduce the disease burden.

Objective To screen the aging-related genes associated with prognosis in clear cell renal cell carcinoma (ccRCC), construct a prognostic model to optimize risk stratification, explore the underlying mechanisms, and provide reference for individualized diagnosis and treatment of this disease.Methods RNA sequencing data, clinical data, and aging-related genes of ccRCC were obtained from databases.After differentially expressed genes were screened, a prognostic model was constructed using Cox regression.The performance of the model was evaluated with Kaplan-Meier curves and receiver operating characteristic (ROC) curves, and validated with clinical features.Key genes were verified with immunohistochemistry.Results A total of 70 differentially expressed genes were identified, including IFI16, PECAM1, and ABCB1 as key genes, and a model formula was constructed.Internal and external validations showed that the survival rate of the high-risk group was significantly lower, with the area under the ROC curve (AUC)＞0.6.The risk score was correlated with clinical features.IFI16 was highly expressed in cancer tissues and associated with poor prognosis.Conclusion The prognostic model constructed in this study has good performance.Integrating clinical features, it can improve the accuracy of prognosis assessment of ccRCC.

ObjectiveTo investigate the effects of three-dimensional foot-ankle exercises (3DFAE) on mild-to-moderate hallux valgus in young women. MethodsFrom October to December, 2024, 45 female patients aged 18 to 26 years with hallux valgus were recruited from Capital University of Physical Education and Sports. They were randomly divided into control group (n = 15), toe-spread-out (TSO) group (n = 15) and 3DFAE group (n = 15). The control group only received foot health education, while the two intervention groups performed corresponding exercise training, for four weeks. Hallux valgus angle (HVA) was measured with photographic method, abductor hallucis activation was detected with surface electromyography, cross-sectional area of abductor hallucis was measured with Doppler ultrasound, and active ankle dorsiflexion range of motion (ROM) was assessed with a goniometer, before intervention, immediately after intervention, and four weeks after training cessation. A perceived difficulty scale was adopted to evaluate the training difficulty of TSO group and 3DFAE group at the first training session and upon completion of intervention. ResultsThe effects of time and interaction were significant for bilateral HVA, abductor hallucis activation, cross-sectional area of abductor hallucis and ankle dorsiflexion ROM (F > 2.728, P < 0.05), and the effect of group of left ankle dorsiflexion ROM was also significant (F = 4.995, P < 0.05). After intervention, bilateral HVA, abductor hallucis activation, cross-sectional area of abductor hallucis and ankle dorsiflexion ROM were all better than those before intervention (P < 0.05), and most indicators were superior to those measured at the 4-week follow-up (P < 0.05). The left ankle dorsiflexion ROM was better in 3DFAE group than in the control group and TSO group (P < 0.05). At the first intervention session, the perceived training difficulty was lower in 3DFAE group than in TSO group (t = 3.334, P = 0.002), and it decreased (t = 5.292, P < 0.001) after four weeks of training in TSO group, with no significant difference compared with 3DFAE group (P > 0.05). Conclusion3DFAE can improve ankle dorsiflexion ROM in young female patients with hallux valgus, with no more difficulty than TSO, and lower initial operation difficulty.

Objectives:To investigate the effect of non-optimal temperature exposure during pregnancy on the risk for preterm birth and identify the susceptible exposure window. At the same time, the interaction between non-optimal temperature and pollutants exposure during pregnancy on preterm birth was analyzed, in order to provide strong clues for the influence of non-optimal temperature exposure during pregnancy on the risk for preterm birth.Methods:A total of 1 852 pregnant women were recruited from September 2021 to June 2023 in Fujian Provincial Maternal and Child Health Care Center. Questionnaire survey was conducted, and their health records were analyzed. The permanent address of each pregnant woman was matched with Fifth Generation European Centre for Medium-Range Weather Forecasts Atmospheric Reanalysis of the Global Climate and a geo-statistical combination model based on satellite remote sensing data collection, then follow-up for pregnancy outcome was conducted. Distributed lag nonlinear model was used to assess the association between exposure to non-optimal temperature during pregnancy and the risk for preterm birth and a multiplicative interaction model was used to assess the interaction between exposure to pollutants and non-optimal temperatures during pregnancy on the risk for preterm birth.Results:After adjusting for potential confounders such as maternal age, occupation, Gross Domestic Product of the region, pre-pregnancy preconception BMI, newborn sex, the weekly susceptibility windows of extreme low temperature ( P1, P3, P5) were week 1-22 , and the weekly susceptibility windows of extreme high temperature ( P95, P97, P99) were week 27 and week 32-36. Extreme low temperature [ P1 ( OR=1.147, 95% CI: 1.041-1.265), P5 ( OR=1.284, 95% CI: 1.035-1.501)] and extreme high temperature [ P97 ( OR=1.146, 95% CI: 1.039-1.263), P99 ( OR=1.216, 95% CI: 1.099-1.345)] exhibited multiplicative interaction with PM 2.5. Conclusions:Exposure to non-optimal temperature during pregnancy was associated with an increased risk for preterm birth. The susceptible exposure windows of extreme low temperature were mainly in early and mid-pregnancy, and the susceptible exposure windows of extreme high temperature were mainly in late-pregnancy. Exposure to non-optimal temperatures and pollutants during pregnancy was associated with an increased risk for preterm birth.

Objective To investigate the differences in pathological changes and immune responses of human airway organoids at different stages of differentiation following respiratory syncytial virus(RSV)infection.Methods Models of human fetal lung organoids(FLO)and induced airway organoids(iAO)were established to simulate immature and mature airway epithelium.Immunofluorescence staining,electron microscopy,and quantitative polymerase chain reaction(Q-PCR)were used to confirm the successful construction of the lung organoid models.Human lung organoids were infected with RSV,and samples were collected at 6 and 48 hours post-infection.The immune characteristics of immature and mature RSV-infected organoids were assessed using immunofluorescence staining,droplet digital PCR(DDPCR),and Q-PCR.Results We successfully generated FLO expressing both the progenitor markers sex determining region Y-box transcription factor 2(SOX2)and sex determining region Y-box transcription factor 9(SOX9),as well as iAO containing basal cells,ciliated cells,club cells,and goblet cells.In addition,organoid models of RSV infection were established.DDPCR results showed that,at the initial stage of RSV infection,the viral load in iAO was significantly higher than that in FLO(P＜0.001).However,at 48 hours post-infection,the viral load in iAO was lower than that in FLO(P＜0.05).Q-PCR results indicated that the expression of RSV infection receptor genes,including epidermal growth factor receptor(EGFR),insulin-like growth factor 1 receptor(IGF1R),and nucleolin(NCL),was significantly higher in iAO compared to that in FLO(P＜0.001).RSV infection led to an increase in the expression levels of immune factors,including interleukin 6(ILL-6),interleukin 8(CXCL8),interferon α(IFN-α),granulocyte colony-stimulating factor(G-CSF),granulocyte-macrophage colony-stimulating factor(GM-CSF),and tumor necrosis factor α (TNF-α),in iAO compared to those in FLO,and the differences were statistically significant(P＜0.05).Conclusion The expression of RSV infection receptor proteins increases with airway maturation,and mature airway epithelial cells exhibit a stronger immune response than immature ones do,effectively inhibiting RSV replication.

Objective:To investigate the relationship between oxidative stress-related genes and pros-tate cancer(PCa)from a multi-omics perspective using summary-data-based Mendelian randomization(SMR),colocalization analysis,and cellular experiments.Methods:Summary-level data on DNA methylation,gene expression,and circulating proteins were obtained and filtered.The PRACTICAL con-sortium was used as the discovery cohort,with the deCODE database serving as the validation cohort.SMR analysis and heterogeneity in dependent instruments(HEIDI)tests were conducted to assess the association and heterogeneity between oxidative stress-related genes and PCa.Colocalization analysis was performed to determine whether oxidative stress-related genes and PCa shared common causal variants.Final-ly,CCK-8 assays,wound healing assays,and Transwell invasion assays and Western blotting,were con-ducted to examine the effects of oxidative stress-related genes on the biological behavior of the PCa cell line C4-2.Results:Multi-omics analysis identified SCP2 as significantly associated with increased PCa risk across gene methylation,gene expression,and circulating protein levels.GSTP1 showed significant associations at the methylation and protein levels,while LPO was associated at the protein level.At the methylation level,SCP2 sites cg00581603(OR=1.11,95％CI:1.05-1.17)and cg13078931(OR=1.12,95％CI:1.05-1.18)were identified as pathogenic.Among the four methylation sites in GSTP1,only cg05244766(OR=0.89,95％CI:0.84-0.95)was considered protective.At the gene expression level,SCP2(OR=1.05,95％CI:1.02-1.07)was also found to be a pathogenic factor.At the circu-lating protein level,SCP2(OR=2.10,95％CI:1.34-3.29)showed a consistent pathogenic trend.In addition,GSTP1(OR=1.16,95％CI:1.07-1.25)and LPO(OR=1.12,95％CI:1.05-1.19)were significantly associated with increased PCa risk.Further functional assays demonstrated that knock-down of SCP2 significantly reduced the oncogenic phenotype of prostate cancer cells.Conclusion:Through integrated multi-omics analysis and experimental validation,this study confirmed a significant as-sociation between SCP2 and increased PCa risk.These findings enhance our understanding of PCa patho-genesis and provide new potential targets and therapeutic directions for PCa treatment.

Objective In this study,we aimed to predict the inhibitory mechanism of Shenlingcao oral liquid(SLC)in non-small cell lung cancer(NSCLC)by network pharmacology and verify it by molecular docking and in vivo experiments.Methods The active ingredients and corresponding targets of SLC and NSCLC were obtained by database and literature search.Targets of SLC common to NSCLC were selected to construct the protein interaction network,and GO and KEGG enrichment analysis and molecular docking were performed.A Lewis lung cancer mouse model was constructed and divided into Model group,SH group,and SL group.The latter two groups were intragastrically administered 8.75 g SLC lyophilized powder/kg and 3.50 g SLC lyophilized powder/kg,respectively.After 14 days of drug intervention,tumor growth,pathological changes in tumor tissue,and apoptosis in tumor tissue were observed in tumor-bearing mice;changes in blood routine indexes and the tumor tissue expression of p-AKT,AKT,p-PI3K,PI3K,and Bcl-2 protein of mice were detected.The result of the KEGG enrichment analysis were verified.Results Network pharmacological analysis showed that there were 77 active ingredients,618 potential targets,1498 potential targets for NSCLC,and 179 drug and disease intersection targets.Target intersection enrichment analysis showed that they were mainly concentrated in the phosphatidylinositol 3 kinase-protein kinase B(PI3K-AKT)signaling pathway,mitogen-activated protein kinase(MAPK)signaling pathway,and other related pathways.Molecular docking showed that the top 10 core components had good bonding ability with the top 10 core targets.In the animal experiments,compared with the Model group,SH group and SL group had significantly decreased tumor volume and weight(P＜0.05,P＜0.01),and significantly decreased white blood cell,neutrophil,and monocyte numbers(P＜0.01,P＜0.001).Red blood cells,platelets,and hemoglobin were significantly increased(P＜0.05,P＜0.01,P＜0.001);apoptotic cells were significantly increased in early tumor tissue(P＜0.05,P＜0.01),and the protein expression levels of p-PI3K/PI3K,p-AKT/AKT,and Bcl-2/GAPDH were significantly decreased(P＜0.05,P＜0.01).The expression levels of PI3K,AKT1,and Bcl-2 genes were significantly decreased(P＜0.05,P＜0.01).Conclusions The mechanisms of SLC activity against NSCLC may be related to the activation of the PI3K-AKT pathway and the promotion of apoptosis.
