Objective: To construct an evaluation index system of cervical cancer prevention and control literacy, so as to provide an assessment tool for cervical cancer prevention and control literacy. Methods: The preliminary framework for cervical cancer prevention and control literacy was designed based on literature review. Twenty-one experts with both theoretical and practical experience in cervical cancer prevention and control were invited to participate in two rounds of Delphi consultation. The weights of indicators were determined by the percentage weighting method and product method, and the response rate, authority level, opinion concentration degree, and coordination degree of experts were evaluated. Results: Twenty-one experts participated in the consultation, including 3 males and 18 females. There were 11 experts with a doctor's degree, 7 with a master's degree and 3 with a bachelor's degree. All of them had senior professional titles and had more than 10 years of working experience. The recovery rates of the two rounds of consultations were 100.00% and 95.24%, the authority coefficients were 0.963 and 0.948, and Kendall's coefficients of concordance were 0.175 and 0.148 (both P<0.05), respectively. The final cervical cancer prevention and control literacy evaluation index system included 3 primary indicators (basic knowledge and concepts: 0.334; healthy lifestyle and behaviors: 0.338; basic skills: 0.328), 12 secondary indicators, with "capability to accurately acquire, comprehend, evaluate and apply health information" having the highest weight (0.166), and 51 tertiary indicators, with "HPV vaccination" (0.086), "consulting on relevant issues" (0.082), and "expressing personal perspectives" (0.080) having relatively higher weights. Conclusion The evaluation index system of cervical cancer prevention and control literacy serves as a valid assessment tool for women of appropriate age, providing the reference for developing targeted health education to enhance cervical cancer prevention and control literacy.

Aim To explore the protective effects of Xiyanping injection against lipopolysaccharide(LPS)-induced acute lung injury(ALI)in mice,and investi-gate the underlying mechanism.Methods In the LPS-induced ALI mouse model,the protective effect of Xiyanping injection against ALI was evaluated by ob-serving the pathological indicators of lung tissue.Net-work pharmacology and molecular docking were used to explore its mechanism.Western blot method was used to validate the predicted target proteins.Results Xiy-anping injection significantly improved the pathological injury and alleviated inflammatory reactions in lungs of ALI mice.Four active ingredients were identified in Xiyanping injection,namely,14-deoxy-11-oxo-an-drographolide,14-deoxyandrographolide,14-deoxy-12-methoxyandrographolide,and andrographolide-19-β-D-glucoside.A total of 288 corresponding drug targets and 4 960 ALI-related targets were obtained,with 192 genes overlapping.The ten core targets associated with Xiyanping injection were identified as STAT3,EGFR,PIK3R1,MAPK1,PIK3CA,NFKB1,ESR1,MAPK8,JAK2,and FYN.GO enrichment analysis re-vealed 310 biological processes(BP),65 cellular components(CC),and 80 molecular functions(MF)associated with the overlapping genes.KEGG pathway enrichment analysis identified 141 pathways related to ALI,with the top 20 pathways including MAPK,TNF-α,VEGF,cAMP,mTOR,AMPK,NOD,JAK-STAT,IL-17,and NF-κB.Molecular docking results demonstrated strong binding affinity between core tar-gets(MAPK1,MAPK8,NFKB1)and active ingredi-ents(14-deoxy-12-methoxyandrographolide and 14-de-oxyandrographolide).Western blotting showed that medium and high doses of Xiyanping injection signifi-cantly downregulated p38,JNK,ERKl/2,NF-κB p65 protein expression in lung tissue of ALI mice(P＜0.01).Conclusions Xiyanping injection has a cer-tain protective effect against ALI,and the mechanism is related to regulating MAPK and NF-κB signaling pathways.

Objective:To establish a multi-factor prediction model for vascular aging based on psychological behavior and physical exercise using nomogram and structural equation method.Methods:A total of 701 inpatients or physical examination patients who underwent carotid ultrasound examination in the Affiliated Hospital of Qingdao University from October 2021 to March 2023 were selected by cross-sectional method. The subjects were randomly divided into training queue( n=492) and verification queue( n=209) according to the ratio of 7∶3.The psychological and behavioral factors, lifestyle, demography and accompanying diseases data were collected. Multi-factor binary Logistic regression method in SPSS 25.0 software was used to screen independent influencing factors of vascular aging, R 4.2.2 software was used to build a nomogram prediction model of vascular aging, and the ROC curve, calibration chart and decision curve analysis were used to evaluate the nomogram, and AMOS software was used to build a structural equation model of vascular aging. Results:Multivariate Logistic regression analysis showed that type A behavior( B=1.757, OR(95% CI)=5.790(2.750-12.210), P<0.001), physical exercise( B=-3.019, OR(95% CI)=0.050(0.020-0.100), P<0.001), high-fat diet( B=0.679, OR(95% CI)=1.970(1.350-2.880), P<0.001), sleep quality( B=-1.451, OR(95% CI)=0.230(0.120-0.460), P<0.001), tea drinking habits( B=-2.349, OR(95% CI)=0.100(0.050-0.200), P<0.001), age( B=0.061, OR(95% CI)=1.060(1.020-1.110), P=0.005), sex( B=-1.263, OR(95% CI)=0.280(0.140-0.570), P<0.001), hyperlipidemia( B=0.679, OR(95% CI)=1.970(1.350-2.880), P<0.001) and diabetes( B=0.838, OR(95% CI)=2.310(1.140-4.700), P=0.021)were independent influencing factors of vascular aging. The nomogram model showed that type A behavior, physical exercise, high-fat diet, sleep quality, tea drinking habits, age, sex, hyperlipidemia and diabetes were independent influencing factors of vascular aging.Advanced age, type A behavior, hyperlipidemia, diabetes and the score of high-fat diet were risk factors for vascular aging, while better sleep quality, tea drinking habit and the score of physical exercise were protective factors for vascular aging.Men were more prone to vascular aging than women. Structural equation model showed that type A behavior had the strongest direct positive effect on vascular aging (the effect coefficient=0.197, P<0.01), and physical exercise had the strongest direct negative effect on vascular aging (the effect coefficient=-0.452, P<0.01), which could indirectly affect vascular aging through various factors. Conclusions:The nomogram model shows the independent influencing factors of vascular aging and has certain predictive value.Structural equation model shows that many factors such as psychological behavior and lifestyle can directly or indirectly affect the occurrence of vascular aging, among which type A behavior and physical exercise have more extensive effects.

Drug resistance presents a significant challenge to achieving positive clinical outcomes in anti-tumor therapy.Prior research has illuminated reasons behind drug resistance,including increased drug efflux,alterations in drug targets,and abnormal activation of oncogenic pathways.However,there's a need for deeper investigation into the impact of drug-resistant cells on parental tumor cells and intricate crosstalk between tumor cells and the malignant tumor microenvironment(TME).Recent studies on extracellular vesicles(EVs)have provided valuable insights.EVs are membrane-bound particles secreted by all cells,mediating cell-to-cell communication.They contain functional cargoes like DNA,RNA,lipids,proteins,and metabolites from mother cells,delivered to other cells.Notably,EVs are increasingly recognized as regulators in the resistance to anti-cancer drugs.This review aims to summarize the mechanisms of EV-mediated anti-tumor drug resistance,covering therapeutic approaches like chemo-therapy,targeted therapy,immunotherapy and even radiotherapy.Detecting EV-based biomarkers to predict drug resistance assists in bypassing anti-tumor drug resistance.Additionally,targeted inhibition of EV biogenesis and secretion emerges as a promising approach to counter drug resistance.We highlight the importance of conducting in-depth mechanistic research on EVs,their cargoes,and functional ap-proaches specifically focusing on EV subpopulations.These efforts will significantly advance the devel-opment of strategies to overcome drug resistance in anti-tumor therapy.
