OBJECTIVES: To analyze the trends of disease burden of lip and oral cancers in East Asia from 1990 to 2021 and its future projections. METHODS: We used the Global Burden of Disease 2021 database to conduct a comprehensive analysis of disease burden data from China (including Taiwan Province of China), Japan, Republic of Korea, Democratic People's Republic of Korea and Mongolia. The data were stratified by age, gender and major risk factors, and a Bayesian age-period-cohort model was employed to predict the future trends. RESULTS: From 1990 to 2021, the burden of lip and oral cancers in East Asian countries exhibited a steady increase. Taiwan Province of China experienced the most significant increases in incidence, prevalence, mortality, and disability-adjusted life years (DALYs), while Mongolia saw a decline in both mortality and DALYs. In 2021, Taiwan Province of China reported the highest rates of lip and oral cancer incidence (27.50 per 100 000), prevalence (137.92 per 100 000), mortality (9.59 per 100 000), and DALYs (292.07 person-years per 100 000), particularly among male and elderly populations. Tobacco use and alcohol consumption significantly exacerbated the disease burden in Taiwan Province of China and Japan. Future projections indicate that the incidence and prevalence of lip and oral cancer in China (excluding Taiwan Province of China) will continue to rise, while their mortality rates are expected to decline in most regions, except for Taiwan Province of China and Democratic People's Republic of Korea. CONCLUSIONS By the year 2035, the disease burden of lip and oral cancers in East Asia is expected to continue to increase, especially in Taiwan Province of China. To address this challenge, it is essential to implement effective measures to control major risk factors, promote early screening, and ensure equitable distribution of healthcare resources.

OBJECTIVE To explore the potential mechanisms of forkhead box protein A1(FOXA1)in benzo[a]pyrene(BaP)-induced carcinogenesis by investigating the effect of FOXA1 by knockout on microRNA(miRNA)expression profiles in BaP malignant transformed cells THBEc1 and establishing regulatory networks between FOXA1,miRNA and their target genes.METHODS FOXA1 knockout THBEc1 cells THBEc1-ΔFOXA1-c34 and control cells THBEc1-ctrl were used as study models.Western blotting was employed to determine FOXA1 protein expression levels.Next-generation sequencing(NGS)tech-nology was used to identify differentially expressed miRNAs between THBEc1-ΔFOXA1-c34 and THBEc1-ctrl cells,with subsequent validation by RT-qPCR.Five databases(ENCORI,miRDB,mirDIP,miRWalk and TargetScan 8.0)were used in conjunction with NGS results of mRNA between THBEc1-ΔFOXA1-c34 and THBEc1-ctrl to predict different expressed genes(DEGs)regulated by the identified differentially expressed miRNAs.GO and KEGG enrichment analyses were conducted on the DEGs using the DAVID database.Interaction network analysis of the proteins encoded by the DEGs was performed using STRING 12.0 and Cytoscape 3.10.2 software.RESULTS No FOXA1 expression was detected in THBEc1-ΔFOXA1-c34 cells.A differential analysis of miRNA expressions revealed 33 miRNAs with a fold change of＞2 or＜0.5 and a false discovery rate of＜0.05 between THBEc1-ΔFOXA1-c34 and THBEc1-ctrl cells,13 of which were down-regulated and 20 were up-regulated in THBEc1-ΔFOXA1-c34 cells.A regulatory network was formed by 11 down-regulated miRNAs and 32 up-regulated mRNAs,while a second network included 16 up-regulated miRNAs and 56 down-regulated mRNAs.The 27 differentially expressed miRNAs participated in various biological processes through the regulation of 88 DEGs,primarily associated with cell growth,proliferation,migration,apoptosis,angiogenesis,epithe-lial-mesenchymal transition,and signal transduction(TGF-β,Hippo,NF-kappa B and MAPK pathways).CONCLUSION The miRNA expression profile in BaP-malignant transformed THBEc1 cells is altered following FOXA1 knockout that may disrupt TGF-β and MAPK signaling pathways by changing miRNA expression levels,thereby inhibiting cell proliferation and migration.

Emerging evidence suggests that dysbiosis of the gut microbiota is associated with the pathogenesis of Parkinson's disease (PD), a prevalent neurodegenerative disorder. The microbiota-gut-brain axis plays a crucial role in the development and progression of PD, and numerous studies have demonstrated the potential therapeutic benefits of modulations in the intestinal microbiota. This review provides insights into the characterization of the gut microbiota in patients with PD and highlights associations with clinical symptoms and underlying mechanisms. The discussion underscores the increased influence of the gut microbiota in the pathogenesis of PD. While the relationship is not fully elucidated, existing research demonstrates a strong correlation between changes in the composition of gut microbiota and disease development, and further investigation is warranted to explain the specific underlying mechanisms.

Objective To investigate the effect and mechanism of melatonin in alleviating hypoxia-induced apoptosis in ovarian gra-nulosa cells.Methods Rat ovarian granulosa cells were isolated and divided into normoxic,hypoxic,and melatonin groups.Hypoxia-induced injury models were established in the hypoxic and melatonin groups,and granulosa cells in the melatonin group were treated with melatonin.A total of 24 rats were randomized into the control,model,and intervention groups(n=8 per group).Rat models of declining ovarian function induced by long-term hypoxia were established in the model and intervention groups.The rats in the intervention group were intraperitoneally injected with melatonin.Cell proliferation was measured using a CCK-8 assay,and lactate secretion and HIF-1αprotein with a specific kit,respectively.The levels of estradiol and progesterone in the cell supernatant and rat serum were detected using ELISA.Granulosa cell apoptosis was detected by flow cytometry,ovarian morphology by HE staining,and Bax and caspase-3 expression by Western blotting.Results Compared with the normoxic group,the hypoxic group exhibited decreased granulosa cell proliferation,increased apoptosis,elevated lactate and HIF-1α levels,and reduced estradiol and progesterone levels(P＜0.05).Compared with hypoxic group,these changes were significantly reversed in the molatonin group(P＜0.05).Compared with the control group,the model group showed increased lactate,HIF-1α,Bax,and caspase-3 levels,decreased estradiol and progesterone levels,and reduced follicles.Compared with the model group,all the indicators were ameliorated in the intervention group(P＜0.05).Conclusion Melatonin alleviated hypoxia-induced granulosa cell apoptosis and promoted the recovery of ovarian function.

Objective To analyze the prevalence and risk factors of underscreening among cervical cancer screening participants in Wuxiang County,Shanxi Province in 2019,providing evidence-based support for optimizing mobilization strategies.Methods Data from cervical cancer screening programs conducted between 2019 and 2024 in Wuxiang County were retrospectively collected.The follow-up screening behaviors of women screened in 2019 were analyzed,and factors associated with underscreening were identified.Results A total of 3759 women underwent cervical cancer screening in 2019.Among them,492 women(13.09％)with abnormal primary screening results requiring follow-up in 12 months,yet only 43(8.74％)completed;2154 women(57.30％)with negative liquid-based cytology testing(LCT)results needed re-screening after 3 years,701(32.54％)completed;1113 women(29.61％)with negative HPV/combined results needed re-screening after 5 years,734(65.95％)completed.Overall,2299 women(60.69％)exhibited underscreening.Multivariate analysis showed that underscreening was more likely among community residents than rural residents(OR=2.309,P=0.018),older women(OR=1.065,P＜0.001),those in organized screening compared to opportunistic screening(OR=3.789,P＜0.001),those undergoing LCT(OR=4.607,P＜0.001)or combined screening instead of human papillomavirus testing(OR=3.624,P＜0.001),and those with abnormal screening results(OR=6.859,P＜0.001).Conclusion Substantial proportions of cervical cancer screening participants demonstrate poor adherence to guideline-recommended screening intervals,and particularly need to focus on older women and those with abnormal screening results.Implementation of electronic screening record systems and emphasizing knowledge of periodical screening in health education could enhance compliance with"70％screening coverage"target for cervical cancer prevention.
