AIM:To investigate the current status and influencing factors of knowledge-attitude-practice in myopia prevention and control among children and adolescents in Ningbo City, thereby providing a scientific basis for formulating targeted prevention strategies.METHODS: Children and adolescents aged 6-12 years old were selected from the medical-school collaborative myopia prevention network in Ningbo City between August 2024 and May 2025 using stratified cluster sampling. Information on myopia prevention knowledge(15 items)and practice(9 items)was collected through questionnaire surveys. Logistic regression models were used to analyze factors influencing myopia occurrence in children and adolescents.RESULTS: A total of 664 children and adolescents aged 6-12 years were enrolled in this study. Participants were divided by age into three groups: 6-7 years old(n=221), 8-9 years old(n=221), and 10-12 years old(n=222). Of the 664 questionnaires distributed, 637 valid questionnaires were returned(201 from the 6-7 age group, 235 from the 8-9 age group, and 201 from the 10-12 age group), yielding an effective response rate of 95.9%. Based on myopia screening results, the non-myopic group comprised 203 participants(31.9%), including 100 males and 103 females, with a mean age of 8.82±1.98 years old. The myopic group comprised 434 participants(68.1%), including 213 males and 221 females, with a mean age of 9.10±1.95 years old. The myopia prevalence rates in the 6-7, 8-9, and 10-12 age groups were 37.8%(76/201), 71.9%(169/235), and 94.0%(189/201), respectively(P<0.001). Regarding the knowledge and practice of myopia prevention, the overall awareness rate in the non-myopic group(59.7%±9.7%)was significantly higher than that in the myopic group(48.7%±8.5%; P<0.001). Additionally, the non-myopic group scored higher on the key practice of “regular eye examinations”(4.27±0.96)compared to the myopic group(4.10±1.05; P<0.05). Logistic regression analysis indicated that age was the primary risk factor for myopia occurrence.CONCLUSION: Age is the dominant factor in the onset of myopia, and there is a phenomenon of “knowledge-practice gap”; the traditional health education model has limitations, and a precise prevention and control system based on developmental patterns should be established.

Objective To investigate whether interleukin-37(IL-37)affects macrophage M1 polarization via nu-cleotide oligomerization of structural domain receptor protein 1(NOD1)/nuclear factor κB(NF-κB)in plasma cell mastitis.Methods A total of 15 patients with plasma cell mastitis were recruited according to the collection standard as inflammatory breast tissue and normal breast tissue with a distance of ≥ 3 cm from the edge of the in-flammatory breast tissue.QPCR was performed to detect NOD1 and IL-3.Phorbol ester(PE)was used to induce THP-1 cells to differentiate into resting macrophages(M0).Lipopolysaccharide(LPS)combined with interferon(IFN-γ)was used to induce the polarization of M0 macrophages towards the M1 phenotype.NOD1 lentiviral RNA interference or over-expression vectors were constructed to regulate the expression of NOD1 in M1 macrophages.M0 macrophages were pretreated with IL-37 recombinant protein and then incubated with LPS and IFN-γ for induction.The expression of NOD1,IL-37,M1 markers(IL-6 and iNOS)and M2 markers(IL-10 and Arg-1)was quantified by qPCR.Western blot was employed to assess the protein level of NOD1,NF-κB p65,and p-NF-κB p65.Co-immunoprecipitation was used to detect the interaction between NOD1 and IL-37.Results Up-regulation of NOD1 and down-regulation of IL-37 as were found in inflammatory breast tissues(P＜0.05).Compared to M0 cells,M1 cells showed up-regulated NOD1 and M1 markers and the elevated phosphorylated NF-κB p65 but the down-regulated IL-37(P＜0.05).In M1 macrophages,both NF-κB inhibitor and NOD1 knockdown led to the down-regulation of NOD1 and M1 markers and caused a decrease in the phosphorylated NF-κB p65(P＜0.05).IL-37 recombinant protein decreased phosphorylation of NOD1,M1 marker and NF-κB p65,which was reversed by over-expression of NOD1.IL-37 may interact with NOD1(P＜0.05).Conclusions IL-37 may inhibit M1 polarization in macrophages by down-regulating NOD1/NF-κB pathway thereby preventing plasma cell mastitis progression.

Objective To analyze the satisfaction of medical experience of outpatients in multi-campus of a large tertiary public hospital.Methods From January to March 2024,a questionnaire on outpatient satisfaction was sent to the outpatient department of Peking University First Hospital daily based on the Questionnaire Star platform to analyze the outpatient satisfaction rate and satisfaction score of medical services,and the influencing factors of outpatient satisfaction were explored by logistic regression analysis.Results Among the respondents,64.0％expressed high levels of satisfaction while 26.1％reported being relatively satisfied.Waiting time and consultation time play an important role.The diagnosis,treatment and health education and schedule of follow-up visits may affect the outpatient experience.Outpatient payment,outpatient environment,outpatient perceived complaints and timely resolution of dissatisfaction all could affect outpatient satisfaction.Conclusion The overall satisfaction of outpatients was high,and patient satisfaction of outpatient medical services in multi-campuses was consistent.On the premise of ensuring the quality of medical care,hospitals should actively carry out individualized health education,simplify the medical process,extend the outpatient service,and further improved the sense of gain of outpatients.

Objective:To observe the level of serum uric acid in young patients with ischemic stroke, and to explore the relationship between the level of serum uric acid and the short-term prognosis of young patients with ischemic stroke.Methods:From July 2020 to December 2022, 93 cases of young patients with ischemic stroke admitted to the Department of Neurology of Tianjin Baodi Hospital were collected as the case group, and 93 cases of healthy people in the physical examination center during the same period were collected as the control group. The clinical data of the two groups were collected and analyzed retrospectively, and the uric acid level of the two groups was compared, and the influence of serum uric acid level on the short-term prognosis of young patients with ischemic stroke was discussed. The measurement data of normal distribution were compared by two independent samples t-test, the measurement data of non-normal distribution were represented by xˉ± s and compared by non-parametric rank sum test, and the count data were represented by M( Q1, Q3) compared by chi-square test, the relationship between uric acid and short-term exacerbation of acute ischemic stroke in young patients was analyzed by binary Logistic multivariate analysis. Results:There was no significant difference in serum uric acid between case group and control group ( P>0.05), The level of serum uric acid in young patients with ischemic stroke in short-term exacerbation group (316.54±128.18) μmol/L was lower than that in stable group (388.62±113.54) μmol/L. The difference was statistically significant ( t=2.21, P=0.030). Conclusion:Elevated serum uric acid level is not an independent risk factor of ischemic stroke in young people, and serum low uric acid level is associated with short-term aggravation of acute ischemic stroke.

In continuation of research aimed at identifying anti-inflammatory agents from natural sesquiterpenoids, an activity-guided fractionation approach utilizing lipopolysaccharide (LPS)-mediated RAW264.7 cells was employed to investigate chemical constituents from Inula Britannica (I. britannica). Seven novel sesquiterpenoid dimers inulabritanoids A-G (1-7) and two novel sesquiterpenoid monomers inulabritanoids H (8) and I (9) were isolated from I. britannica together with eighteen known compounds (10-27). The structural elucidation was accomplished through comprehensive analysis of 1D and 2D nuclear magnetic resonance (NMR), high-resolution mass spectrometry (HR-MS), and electronic circular dichroism (ECD) spectra, complemented by quantum chemical calculations. Compounds 1, 2, 12, 16, 19, and 26 demonstrated inhibitory effects on NO production, with IC₅₀ values of 3.65, 5.48, 3.29, 6.91, 3.12, and 5.67 μmol·L^-1, respectively. Mechanistic studies revealed that compound 1 inhibited IκB kinase β (IKKβ) phosphorylation, thereby blocking nuclear factor κB (NF-κB) nuclear translocation, and activated the kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signal pathway, leading to decreased expression of NADPH oxidase 2 (NOX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), IL-1β, and IL-1α and increased expression of NAD(P)H: quinone oxidoreductase 1 (NQO-1) and heme oxygenase-1 (HO-1), thus exhibiting anti-inflammatory effects in vitro. These results indicate that dimeric sesquiterpenoids may serve as promising candidates for anti-inflammatory drug development.

Objective:To construct a VP8-mRNA vaccine using human rotavirus spike protein VP8 domain as the immunogen and analyze its immunogenicity in mice.Methods:The VP8-mRNA sequence was designed, optimized, and synthesized. The VP8 gene of rotavirus G1P[8] type was used to construct the plasmid pUC57-VP8-Kan-SapⅠ, which was then sequenced. The plasmid confirmed by sequencing was subjected to large-scale amplification and extraction, followed by linearization, in vitro transcription, and capping. The purified capped products were encapsulated with lipid nanoparticles using a microfluidic control apparatus. The encapsulated VP8-mRNA vaccine was administered intramuscularly to mice at 10, 15, and 20 μg. Serum samples were collected for antibody detection by ELISA. Cellular immune responses were detected by flow cytometry and ELISPOT. Statistical analysis was performed using one-way or two-way analysis of variance and Tukey-Kramer test. Results:The encapsulated VP8-mRNA vaccine was rounded and spherical, with a particle size of about 100 nm, a polymer dispersion index of 0.088, and an encapsulation rate of 92.3%. Two doses of VP8-mRNA vaccine immunization could induce a good immune response in mice. The level of IgG antibody induced after immunization in the 15 μg group was comparable to that of the 20 μg group, and there was no statistical difference ( P>0.05), but the antibody levels in the two groups were significantly higher than that in the 10 μg group ( P<0.000 1). VP8-mRNA vaccine could induce neutralizing antibodies against rotavirus G1 and G9 types. The highest level of neutralizing antibodies against rotavirus type G1 was observed in the 15 μg group, which was significantly higher than that in the 10 μg group ( P<0.05). All immunization groups exhibited good neutralizing ability against rotavirus G9 type. The results of ELISPOT showed that lymphocytes from mice in each vaccine group were able to secrete IFN-γ when stimulated with VP8 peptide. Flow cytometry showed that the proportions of CD8 + T cell subsets in the vaccine groups were higher than that in the control group. Conclusion:The VP8-mRNA vaccine has good immunogenicity in mice and can induce good humoral and T-cell immune responses.
