Objective To screen ferroptosis genes related to the prognosis of cervical cancer and to construct a prognosis model. Methods Ferroptosis genes were obtained from FerrDb database, and cervical cancer related data were obtained from The Genome-Wide Association Study Catalog database and The Cancer Genome Atlas database. Transcriptome-Wide Association Study, colocalization analysis and differential expression analysis were conducted to screen out candidate ferroptosis genes; Gene Ontology functional and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were conducted on candidate genes. Univariate Cox regression analysis was used to further screen out genes related to the prognosis of cervical cancer. Kaplan-Meier method was used to analyze the relationship between genes and the overall survival of patients. The expression levels of genes in pan-cancer were analyzed through the TIMER database. Two prognostic models were conducted, Model 1 included age and tumor stage, while Model 2 incorporated age, tumor stage, and prognostic genes. The predictive capabilities of the two models were compared. Results A total of 91 candidate genes related to ferroptosis were obtained. Univariate Cox regression analysis showed that 15 genes were associated with the prognosis of cervical cancer. CA9, SCD, TFRC, QSOX1 and CDO1 were risk factors affecting the prognosis of cervical cancer patients (P＜0.05), while PTPN6, ALOXE3, HELLS, IFNG, MIOX, ALOX12B, DUOX1, ALOX15, AQP3 and IDO1 were protective factors (P＜0.05). The mRNA expression levels of the 15 genes showed significant upregulation or downregulation in at least 7 types of cancers, among which TFRC was associated with the largest number of cancer types. Kaplan-Meier analysis showed that HELLS, DUOX1 and ALOXE3 were associated with poor prognosis in cervical cancer. The AUC of the model 1 for predicting 1-year and 3-year overall survival rates of cervical cancer patients was 0.455 and 0.478, and the AUC of Model 2 was 0.854 and 0.595. Model 2 (C-index = 0.727) had better predictive ability than Model 1 (C-index = 0.502). Conclusion The prognostic model composed of 15 prognostic-related genes selected based on bioinformatics has better predictive performance for the survival outcomes of cervical cancer patients, providing important reference value for the prognostic assessment of cervical cancer patients.

Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

Cholangiocarcinoma (CCA) is a fatal malignancy with steadily increasing incidence and poor prognosis. Since most CCA cases are diagnosed at an advanced stage, systemic therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy, play a crucial role in the management of unresectable CCA. The recent advances in targeted therapies and immunotherapies brought more options in the clinical management of unresectable CCA. This review depicts the advances of targeted therapies and immunotherapies for unresectable CCA, summarizes crucial clinical trials, and describes the efficacy and safety of different drugs, which may help further develop precision and individualization in the clinical treatment of unresectable CCA.

Microbial communities such as those residing in the human gut are highly diverse and complex, and many with important implications for health and diseases. The effects and functions of these microbial communities are determined not only by their species compositions and diversities but also by the dynamic intra- and inter-cellular states at the transcriptional level. Powerful and scalable technologies capable of acquiring single-microbe-resolution RNA sequencing information in order to achieve a comprehensive understanding of complex microbial communities together with their hosts are therefore utterly needed. Here we report the development and utilization of a droplet-based smRNA-seq (single-microbe RNA sequencing) method capable of identifying large species varieties in human samples, which we name smRandom-seq2. Together with a triple-module computational pipeline designed for the bacteria and bacteriophage sequencing data by smRandom-seq2 in four human gut samples, we established a single-cell level bacterial transcriptional landscape of human gut microbiome, which included 29,742 single microbes and 329 unique species. Distinct adaptive response states among species in Prevotella and Roseburia genera and intrinsic adaptive strategy heterogeneity in Phascolarctobacterium succinatutens were uncovered. Additionally, we identified hundreds of novel host-phage transcriptional activity associations in the human gut microbiome. Our results indicated that smRandom-seq2 is a high-throughput and high-resolution smRNA-seq technique that is highly adaptable to complex microbial communities in real-world situations and promises new perspectives in the understanding of human microbiomes.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

Objective To explore the efficacy of retropubic midurethral synthetic sling(RMUS)in relieving urgency and urge urinary incontinence(UUI)symptoms in patients with mixed urinary incontinence(MUI).Methods Clinical data of 44 female MUI patients treated with RMUS during Jan.2018 and Dec.2020 in Shanghai Renji Hospital were retrospectively analyzed.All patients had positive results in stress test and Marshall-Marchetti test before operation,and 27 of them completed ICIQ-FLUTS-LF questionnaire.Urodynamic(UDS)tests suggested that 9 patients(20.5％)presented detrusor overactivity(DO).During RMUS procedure,the tension of the sling was adjusted based on the anatomical landmarks.The postoperative efficacy and improvement of urinary incontinence were analyzed.Results The patients aged(58.59±9.08)years,with a body mass index of 24.71±2.77.Among the 40 patients who completed telephone interview 2 years after surgery,the subjective cure rate was 85.0％(34/40).Among the 27 patients with records of questionnaires before and after surgery,there were significant differences in the incidence of urine leakage[100％(27/27)vs.18.5％(5/27)],stress urinary incontinence(SUI)[100％(27/27)vs.18.5％(5/27)]and UUI[70.4％(19/27)vs.29.6％(8/27)](P＜0.05).However,no statistical differences were found regarding nocturia voiding episode(≥1 times),urgency,dysuria,hesitancy,strain to void,intermittent stream and enuresis(P＞0.05).Based on preoperative UDS test,there were significant differences regarding the subjective cure rate in patients with or without preoperative DO[55.6％(5/9)vs.93.5％(29/31)],incidence of SUI[66.7％(4/6)vs.4.8％(1/21)],and UUI[66.7％(4/6)vs.19.0％(4/21)](P＜0.05),while there was no statistical difference regarding urgency[66.7％(4/6)vs.33.3％(7/21)](P＞0.05).Conclusion RMUS is effective in treating MUI patients with positive stress test and Marshall-Marchetti test results,which can relieve SUI and UUI symptoms,but has no effects on urgency symptoms.DO on preoperative urodynamics results in poorer subjective outcomes.

BACKGROUND:Functional training has been popular in recent years,but it is mainly applied in sports training field.There are still insufficient studies and applications in medical and health fields. OBJECTIVE:To provide a theoretical basis for relevant research in sports,medical and health fields,through a more comprehensive and in-depth exploration and analysis of the research hot spots,ideological trends,frontiers and development trends of international functional training in the field of medical and health care. METHODS:The 2 206 high-quality articles addressing health-related functional training during 2012-2022 were exported from the Web of Science Core Set Database as the object of analysis.Combined with research methods such as literature analysis,Citespace V analysis software was used for visual analysis of keywords,subject categories and highly cited literatures. RESULTS AND CONCLUSION:The number of articles published on functional training in the field of health is on the rise.There are more articles from the United States,with a larger impact.China also has a high volume of publications,but the impact and depth of research is lacking.Improving physical and mental health and cognitive ability of middle-aged and older people is the main focus,followed by preventing sports injuries and promoting recovery in athletes.In the future,more research will be conducted on teenagers,the disabled and other groups,and there will be a continued increase in injury prevention and recovery promotion for athletes.Chinese scholars have less research on the effects of functional training on the physical health of the general public,and more attention should be paid to improving the physical and mental health of the general public.

The findings suggest technical rationality and operability of relevant standard should be considered when under revision, and standard training and supervision management should be strengthened, with the aim of teaching environment improvement.

Objective To investigate the changes of OAT expression in bone cells in chronic renal failure(CRF)and involved mechanism,and to explore the effect of OAT expression on bone metabolism.Methods Ra-ndomly divide the rats into a control group(n=6)and a model group(n=6).The model group established a rat chronic renal failure model using"single nephrectomy+adenine gavage"method,and the red blood cell(RBC)and hemoglobin(HGB)of the rat body were measured using a blood routine analyzer;Measure indicators such as creatinine(Cr),urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),and blood phosphorus(P3+)using a fully automated biochemical analyzer;Pathological examination of rat kidneys;X-ray examination of rat tibia;Immunohistochemical examination of bone tissue OAT1 level.Results The bone density of the model group rats is lower than that of the control group;The calcium and phosphorus metabolism of rats in the model group was in metabolic disorder,and the OAT1 value of bone tissue binding was much lower than that of the control group(P= 0.0018),which was statistically significant.(P=0.0018)Conclusion Chronic renal failure affected the binding ability of OAT1 in bone tissue,leading to the metabolic disorder for calcium absorption and phosphorus metabolism,thus aggravating renal osteodystrophy(P<0.05).

ObjectiveTo investigate the possible mechanism of Huatan Sanjie Formula （化痰散结方， HSF） in treating Graves' disease （GD） from the perspective of thyroid angiogenesis. MethodsThirty-six BALB/c female mice were randomly divided into a normal control group （n=9） and a modeling group （n=27）. Mice in the modeling group were injected with 2.0×10⁹ PFU/ml of Ad-TSHR289 adenovirus into the tibialis anterior muscle to build GD model. Nine weeks after immunization， the successfully modeled mice were randomly divided into model group， methimazole （MMI） group and HSF group， with 9 mice in each group. The MMI group was given 5.2 mg/（kg·d） of methimazole tablets by gavage， while the HSF group was given HSF at a relative crude drug dosage of 7.02 g/（kg·d） by gavage. The normal control group and the model group were given 0.1 ml/10 g of pure water by gavage. All groups were administered intragastrically once a day for a total of 4 weeks. The levels of thyroxine （T4） and thyrotropin receptor autoantibodies （TRAb） in serum were detected by radioimmunoassay， while the pathological changes of the thyroid gland were assessed by HE staining. The vascular morphology of thyroid tissue was observed by CD34 immunohistochemical staining， and the microvessel density （MVD） was counted. The protein expression of vascular endothelial growth factor A （VEGFA） and vascular endothelial growth factor receptor 2 （VEGFR2） in thyroid was detected by Western-blot. ResultsCompared to those in the normal control group， the thyroid volume of the mice in the model group significantly increased with excessive congestion， and the pathology showed significant thyroid follicular hyperplasia， columnar and proliferated epithelial cells， and enlarged follicle size； serum T4 and TRAb significantly increased， as well as the count of thyroid MVD， and the protein expressions of thyroid VEGFA and VEGFR2 （P＜0.01）. Compared to those in the model group， the thyroid glands of the mice in the MMI group and the HSF group were significantly reduced， and the congestion was improved； pathology showed that thyroid follicular hyperplasia and epithelial cell proliferation were reduced， with smooth edges of the follicles and the significantly reduced inward protrusion； serum T4 and TRAb significantly decreased， as well as the thyroid MVD， thyroid VEGFA and VEGFR2 protein expressions （P＜0.05 or P＜0.01）. There was no significant difference in all indicators between the MMI group and the HSF group （P＞0.05）. ConclusionHSF may inhibit thyroid angiogenesis by down-regulating thyroid VEGFA/VEGFR2 signaling pathway， thereby improving goitre and hyperfunction in GD mice.
