AIM:To evaluate the accuracy of a portable non-contact tonometer(PNCT)compared with a traditional non-contact tonometer(NCT)in measuring intraocular pressure(IOP)at different levels.METHODS:Patients who presented to Ningbo Eye Hospital between January 2025 and January 2026 were retrospectively included. All patients underwent measurements using PNCT, NCT, and Goldmann applanation tonometry(GAT). Based on the GAT measurements, the patients were categorized into a low IOP group(IOP≤16 mmHg), a moderate IOP group(16 mmHg0.05). Spearman correlation analysis revealed that the IOP values measured by both PNCT and NCT were positively correlated with those measured by GAT(rs=0.86 and 0.84, respectively, P<0.05). Intraclass correlation coefficient(ICC)analysis demonstrated an ICC of 0.89 between PNCT and GAT(P<0.05), and 0.88 between NCT and GAT(P<0.05), with an overall ICC of 0.88 among the three instruments(P<0.05). Bland-Altman analysis indicated a mean bias of 0.1 mmHg [95% limits of agreement(LoA): -7.3 to 7.6 mmHg] between PNCT and GAT, and a mean bias of 0.1 mmHg(95%LoA: -8.4 to 8.6 mmHg)between NCT and GAT. Based on the GAT measurements, the eyes were categorized into a low IOP group(60 eyes, 32.6%, IOP≤16 mmHg), a moderate IOP group(63 eyes, 34.2%, 16 mmHg0.05), whereas the difference between NCT and GAT showed a positive correlation with CCT(rs=0.23, P<0.05).CONCLUSION:The IOP measurements obtained by PNCT, NCT, and GAT demonstrated strong correlation and good agreement, with PNCT being less influenced by CCT. However, as IOP levels increased, the measurement errors of both PNCT and NCT also increased. Therefore, PNCT and NCT readings should only serve as references and cannot replace GAT.

Allergic rhinitis (AR), a globally prevalent immune-mediated inflammatory condition, is still an incurable disease. In the present study, we have validated the impact of the Kelch-like ECH associated protein 1 (Keap1)-related oxidative stress and inflammatory response in clinical AR patient peripheral blood and nasal swab samples, emphasizing the biological relevance of Keap1 and AR. Targeting Keap1 -nuclear factor erythroid 2-related factor 2 (Nrf2) related anti-oxidative stress may be effective for AR intervention. Drawing inspiration from the Keap1 homodimerization and the E3 ligase characteristics, we herein present a design of novel bivalent molecules for chemical knockdown of Keap1. For the first time, we characterized ternary complexes of Keap1 dimer and one molecule of bivalent compounds. The best bivalent molecule 8 encompasses robust capacity to degrade Keap1 as a homoPROTAC^KEAP1. It efficaciously suppresses inflammatory cytokines in extensively different cells, including human nasal epithelial cells. Moreover, in an AR mouse model, we confirmed that the chemical degradation induced by homoPROTAC^KEAP1 led to therapeutic benefits in managing AR symptoms, oxidative stress and inflammation. In summary, our findings underscore the efficacy of targeting the Keap1 system through the homoPROTAC-ing technology as an innovative and promising treatment strategy for the incurable allergic disorders.

Idiopathic pulmonary fibrosis (IPF), a chronic interstitial lung disease, is characterized by aberrant wound healing, excessive scarring and the formation of myofibroblastic foci. Although the role of alternative splicing (AS) in the pathogenesis of organ fibrosis has garnered increasing attention, its specific contribution to pulmonary fibrosis remains incompletely understood. In this study, we identified an up-regulation of serine/arginine-rich splicing factor 7 (SRSF7) in lung fibroblasts derived from IPF patients and a bleomycin (BLM)-induced mouse model, and further characterized its functional role in both human fetal lung fibroblasts and mice. We demonstrated that enhanced expression of Srsf7 in mice spontaneously induced alveolar collagen accumulation. Mechanistically, we investigated alternative splicing events and revealed that SRSF7 modulates the alternative splicing of pyruvate kinase (PKM), leading to metabolic dysregulation and fibroblast activation. In vivo studies showed that fibroblast-specific knockout of Srsf7 in conditional knockout mice conferred resistance to bleomycin-induced pulmonary fibrosis. Importantly, through drug screening, we identified lomitapide as a novel modulator of SRSF7, which effectively mitigated experimental pulmonary fibrosis. Collectively, our findings elucidate a molecular pathway by which SRSF7 drives fibroblast metabolic dysregulation and propose a potential therapeutic strategy for pulmonary fibrosis.

Objective To compare the safety and efficacy of directional atherectomy with anti-restenosis therapy(DAART,drug-coated balloon)versus conventional balloon angioplasty(bare-metal stent,BMS)in elderly patients with femoropopliteal artery disease.Methods A retrospec-tive cohort study was conducted on 116 elderly patients undergoing endovascular intervention due to femoropopliteal artery disease in our hospital between May 2016 and September 2019,divided into DAART group(57 cases)and BMS group(59 cases).Results No statistical differences were observed between the DAART and BMS groups in terms of age,risk factors,distribution of Ruth-erford classification,lesion length,lesion type,lesion location,Global Limb Anatomic Staging Sys-tem grade,infra-popliteal runoff status,or preoperative ankle-brachial index(P＞0.05).However,the BMS group had significantly larger proportion of chronic limb-threatening ischemia than the other group(P＜0.05).Both groups achieved a 100％success rate of surgery.The DAART group obtained obviously higher primary patency rates at 1 and 2 years than the BMS group(90.4％vs 75.0％,76.3％vs 57.3％;P＜0.045).There were no significant differences in the rate of freedom from target lesion revascularization at 1 and 2 years between the two group(96.1％vs 88.8％,91.6％vs 77.7％;P＞0.05).In 2 years of follow-up,the incidence of major adverse events was 10.0％(5 cases)in the DAART group and 20.8％(12 cases)in the BMS group,but no obvious difference(P＞0.05).Conclusion DAART demonstrates superior mid-term efficacy than BMS in treating femoropopliteal artery disease in elderly patients.However,comprehensive preoperative assessment is essential to optimize individualized treatment strategies for this population.

Objective To investigate the mechanism and optimal concentration of anrotinib on ovarian clear cell carcinoma.Methods Ovarian clear cell carcinoma cells were cultured in vitro,by using renal clear cell carcinoma cells and renal papillary cell carcinoma cells as control cancer cells,and the effects of different concentrations of anlotinib(5,10,15,20μmol/L)on the proliferation,migration,and invasion capabilities of three cancer cell lines were investigated.Compared with the experimental results of renal clear cell carcinoma cells and renal papillary cell carcinoma cells,the advantages of anlotinib on ovarian clear cell carcinoma cells were investigated and advanced its position in clinical practice.Results Anlotinib at the concentrations of 5,10,15,and 20μmol/L can effectively inhibit the proliferation,migration,and invasion ability of ovarian clear cell carcinoma cells,renal clear cell carcinoma cells,and renal papillary cell carcinoma cells.Among them,the optimal action concentration of anlotinib on all three cancer cells fell in the range of 5-10 μmol/L.However,in the three cancer cells,anlotinib was more potent in ovarian clear cell carcinoma cells.Conclusion The effect of anlotinib on ovarian clear cell carcinoma cells has obvious advantages over renal clear cell carcinoma cells and renal papillary cell carcinoma cells,with the optimal concentration of 5-10 μmol/L.

OBJECTIVE To elucidate the burden of lower respiratory tract infections(LRIs)attributable to non-op-timal temperature risk and its changing trends in China from 1990 to 2021,and to provide insights for identifying susceptible populations.METHODS The changing trends in mortality and disability-adjusted life years(DALYs)of LRIs attributed to non-optimal,low and high temperature risks were analyzed through the 2021 global burden of disease(GBD)database.Joinpoint software was used to analyze the trend changes of time series and explore the standardized mortality rate and the standardized DALYs rate of LRIs attributed to non-optimal temperature risk.RESULTS In 2021,LRIs mortality and DALYs rates attributable to non-optimal temperature risk in China were 1.92 per 100,000(down 66.80%from 5.76 per 100,000 in 1990)and 37.99 per 100,000(down 90.47%from 398.77 per 100,000 in 1990),respectively.The burden of LRIs attributed to non-optimal temperature risks was higher in males than that in females,with the mortality rates of 2.86 per 100,000 and 2.48 per 100,000,and DA-LYs rates of 44.90 per 100,000 and 30.75 per 100,000,respectively.The burden of LRIs increased significantly in children under 5 years old and elderly individuals aged 75 and above.From 1990 to 2021,the standardized mortali-ty rate and the standardized DALYs rate of LRIs attributed to non-optimal temperature factors in China showed a declining trend[average annual percentage change(AAPC):-5.04%and-7.33%,respectively].CONCLUSIONS The overall burden of LRIs attributable to non-optimal temperature in China has generally declined from 1990 to 2021.with higher burden in males than that in females,and higher burden in individuals under 5 years old and those aged 75 and above.In China,low temperature risk plays an important role in the non-optimal temperature effect.To reduce the burden of LRIs disease,early intervention measures should be implemented for males,the middle-aged and elderly people and children,and early protection for susceptible populations should be provided based on changes in external environmental temperature,which are of significant public health importance for re-ducing disease burden.

Objective: To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion. Methods: Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents. Results: In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14)，and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05). Conclusions The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

Objective: To systematically review the development and changes in mental health policies within the National Outline for Children s Development in China from 1992 to 2030, providing a reference basis for future formulation of mental health policies among children and adolescent in China. Methods: Based on the four editions of the National Outline for Children s Development in China across different periods from 1992 to 2030, word frequency analysis was used to reveal shifts in policy priorities, and an internationally recognized framework for adolescent health policy analysis was applied to conduct a textual review. Results: Word frequency analysis revealed that the term "psychological" appeared 6 times in the National Outline for Children s Development in China (2001-2010) but increased to 20 times in the National Outline for Children s Development in China (2021-2030) (abbreviated as the National Outline of 2021), while the term "health" rose from 4 times in the National Outline for Children s Development Plan in China in the 1990s to 68 times in the National Outline of 2021. The scope of mental health policy interventions expanded to encompass five key areas:health, safety, education, welfare and legal protection. Textual analysis highlighted that the policies of the National Outline for Children s Development in China were demand driven, prioritized vulnerable groups and continuously broadened their coverage, emphasizing sustainability and appropriateness, and monitoring/evaluation mechanisms. By 2023, 42.3% of primary schools and 64.8% of secondary schools employed full time mental health education teachers. However, the National Outline for Children s Development in China lacked direct evidence of children and adolescents participation in policy formulation, and publicly available mental health data disaggregated by age and gender remained limited. Conclusion Mental health policies of children and adolescents in China have evolved from nonexistence to gradual refinement, yet institutionalized channels for youth involvement in policy development and evaluation remain insufficient, and transparency in age and gender specific mental health data needs improvement.
