Objective: To explore the association of outdoor activity time and sleep duration with screening myopia in primary school students, so as to provide strategies for myopia prevention. Methods: Through a convenience sampling method, a survey was conducted among 4 248 primary school students aged 7-13 years from three primary schools in Xihu District, Nanchang City, Jiangxi Province from May to July, 2023. The average daily outdoor activity time and sleep duration on both weekdays and weekends were investigated in primary school students by using a self designed questionnaire. Uncorrected visual acuity tests and non cycloplegic autorefraction were measured by professional optometrists. Inter group comparisons were conducted using the Chi square test. Logistic regression model was used to analyze the association of outdoor activity time and sleep duration with screening myopia. Results: The detection rate of screening myopia in primary school students was 33.6%, with the rate in boys (32.0%) lower than that in girls (35.3%), and the difference was statistically significant ( χ 2=5.11, P =0.02). The analysis results of Logistic regression showed that after adjusting for factors such as gender, grade and parental education level, both average daily outdoor activity time ＜2 h on both weekdays and weekends ( OR =1.27, 95% CI =1.11-1.46) and sleep duration <10 h ( OR =1.17, 95% CI =1.01- 1.35 ), as well as their combined effect ( OR =1.57, 95% CI =1.25-1.98), were associated with an increased risk of screening myopia in primary school students(all P <0.05). Subgroup analysis results indicated that compared to boys ( OR =1.46, 95% CI = 1.07 -1.99), girls( OR =1.73, 95% CI =1.22-2.44) with insufficient outdoor activity time and sleep duration had a higher risk of screening myopia(both P <0.05). Conclusions There is a negative correlation of outdoor activity time and sleep duration with screening myopia in primary school students. Outdoor activity time and extending sleep duration should be increased to reduce the risk of myopia in primary school students.

This paper reports the clinical characteristics as well as diagnosis and treatment processes of a patient with mixed pulmonary infection of Rhizopus microspores and Aspergillus.The patient had history of type 2 diabe-tes mellitus,and was admitted to the hospital due to diabetes ketoacidosis complicated with pneumonia.Clinical manifestations included cough,expectoration,and fever.Imaging examination showed inflammatory lesions of bila-teral lungs(mainly in the right lung)associated with local consolidation.Bronchoalveolar lavage fluid(BALF)smears and galactomannan antigen test(GM test)were both negative.Nucleic acid sequences of Rhizopus micro-spores and Aspergillus were detected by metagenomic next-generation sequencing(mNGS)at the early stage,while complicated infection of Klebsiella pneumoniae and COVID-19 were also found.The final pathological diagnosis was pulmonary mucormycosis combined with invasive pulmonary aspergillosis.The patient achieved clinical curing through the combination of isaconazole antifungal treatment and lobectomy of the right middle-lower lobes.

OBJECTIVES: Neuropathic pain (NP) is one of the most common forms of chronic pain, yet current treatment options are limited in effectiveness. Peripheral nerve injury activates spinal microglia, altering their inflammatory response and phagocytic functions, which contributes to the progression of NP. Most current research on NP focuses on microglial inflammation, with relatively little attention to their phagocytic function. Early growth response factor 2 (EGR2) has been shown to regulate microglial phagocytosis, but its specific role in NP remains unclear. This study aims to investigate how EGR2 modulates microglial phagocytosis and its involvement in NP, with the goal of identifying potential therapeutic targets. METHODS: Adult male Sprague-Dawley (SD) rats were used to establish a chronic constriction injury (CCI) model of the sciatic nerve. Pain behaviors were assessed on days 1, 3, 7, 10, and 14 post-surgery to confirm successful model induction. The temporal and spatial expression of EGR2 in the spinal cord was examined using real-time quantitative PCR (RT-qPCR), Western blotting, and immunofluorescence staining. Adeno-associated virus (AAV) was used to overexpress EGR2 in the spinal cord, and behavioral assessments were performed to evaluate the effects of EGR2 modulation of NP. CCI and lipopolysaccharide (LPS) models were established in animals and microglial cell lines, respectively, and changes in phagocytic activity were measured using RT-qPCR and fluorescent latex bead uptake assays. After confirming the involvement of microglial phagocytosis in NP, AAV was used to overexpress EGR2 in both in vivo and in vitro models, and phagocytic activity was further evaluated. Finally, eukaryotic transcriptome sequencing was conducted to screen differentially expressed mRNAs, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses to identify potential downstream effectors of EGR2. RESULTS: The CCI model successfully induced NP. Following CCI, EGR2 expression in the spinal cord was upregulated in parallel with NP development. Overexpression of EGR2 via spinal AAV injection enhanced microglial phagocytic activity and increased pain hypersensitivity in rats. Both animal and cellular models showed that CCI or LPS stimulation enhanced microglial phagocytosis, which was further amplified by EGR2 overexpression. Transcriptomic analysis of spinal cord tissues from CCI rats overexpressing EGR2 revealed upregulation of numerous genes associated with microglial phagocytosis and pain regulation. Among them, Lag3 emerged as a potential downstream target of EGR2. CONCLUSIONS EGR2 contributes to the maintenance of NP by enhancing microglial phagocytosis in the spinal dorsal horn.

Objective To explore the current status and its influencing factors of electronic health literacy of caregivers of total laryngectomy patients and its influencing factors.Methods A total of 145 caregivers of total laryngectomy patients who were admitted to The First Affiliated Hospital of Naval Medical University from August 2018 to August 2023 were selected by convenience sampling.A questionnaire survey was conducted on these caregivers by demographic data questionnaire,electronic health literacy scale(e-HLS),and general self-efficacy scale.Results The average total score of electronic health literacy among the caregivers was 25.09±5.31.One-way analysis of variance showed that there were significant differences in the scores of e-HLS among caregivers with different age,education level,self-efficacy,frequency of online health information search,and disease course(P<0.05).Multivariate logistic regression analysis showed that age,education level,self-efficacy,frequency of online health information search,and disease course were the main factors affecting the electronic health literacy of caregivers of total laryngectomy patients.Conclusion Electronic literacy of caregivers of total laryngectomy patients is at a low level,and it was affected by many factors.Appropriate guidance can be provided to caregivers with low electronic health literacy,so as to improve the electronic health literacy of caregivers and the quality of care for total laryngectomy patients.

Objective:To investigate the clinical characteristics of sepsis-induced myocardial injury and microbial distribution.Methods:It was a retrospective observational study conducted from Jan 2023 to Dec 2023 in the Department of Emergency Intensive Care Medicine, Changshu Hospital Affiliated to Soochow University. Patients meeting the sepsis 3.0 criteria were included, excluding those with underlying cardiovascular diseases or incomplete data. Patients were categorized into myocardial injury (SIMI) and non-myocardial injury (Non-SIMI) groups based on troponin levels. General patient information, laboratory results, microbial findings, and prognostic indicators were collected. Differences in clinical parameters between the two groups were compared. Factors showing statistical differences in univariate analysis were further analyzed using multivariable logistic regression to identify risk factors for SIMI. Conduct propensity score matching among Pulmonary infection patients who underwent bronchoalveolar lavage high-throughput sequencing to compare microbial distribution between groups. Bracken was used to estimate species-level abundance from Kraken2 results, and α and β diversity analyses were conducted on the metagenomic samples.Results:A total of 179 patients were included in the study, with 98 (54.4%) in the Non-SIMI group and 81 (45.5%) in the SIMI group. There were 69 deaths overall (38.5%), with 23 (23.7%) in the Non-SIMI group and 46 (56.8%) in the SIMI group (χ 2=20.347, P<0.01). The 28-day survival curve indicated survival rates in the SIMI group were significantly lower compared to the Non-SIMI group (Log Rank χ 2=21.270, P<0.01). Univariate analysis revealed that fungal infection rate ( P=0.007), C-reactive protein ( P=0.021), procalcitonin, blood urea nitrogen, creatinine, alanine transaminase, and lactate levels were higher in the SIMI group compared to the Non-SIMI group (all P<0.01), prothrombin time was prolonger ( P<0.01) and APACHEⅡ scores were higher ( P<0.01), while serum albumin, base excess, and platelet levels were lower (all P<0.01). Multivariable logistic regression analysis indicated that fungal infection ( OR=3.441, P=0.015) was a risk factor for SIMI, whereas base excess and platelets were protective factors ( OR=0.845, 0.988, both P<0.01). Comparison of bronchoalveolar lavage high-throughput sequencing results in the pulmonary infection subgroup showed the relative abundance of Haemophilus paraininfluenzae in Non-SIMI group was higher than SIMI group among the top 20 species ( P=0.013). There were no statistically significant differences in microbial αand β-diversity between the two groups. Conclusions:The incidence of SIMI is relatively highamong sepsis patients and it affects their prognosis. Risk factors for SIMI include fungal infection, decreased platelet count, and reduced base excess levels. Among patients with pulmonary infections, there is a lower risk of SIMI associated with Haemophilus influenzae infection.

Objective To explore the application effect of midazolam combined with oxycodone in fiberoptic bronchoscope intubation of burn patients with difficult airway.Methods 80 burn patients with difficult airway who underwent fiberoptic bronchoscope intubation from March 2023 to March 2024 were included as the study subjects.They were assigned into two groups based on anesthesia medication:the control group(40 cases)was given midazolam anesthesia,and the combined group(40 cases)was given midazolam combined with oxycodone anesthesia.The one-time success rate of intubation,hemodynamic indicators[heart rate(HR),mean arterial pressure(MAP),and percutaneous arterial oxygen saturation(SpO2)],Ramsay sedation score,and adverse reactions were compared between the two groups.Results The success rate of intubation in the combined group(95.00%)was higher than that in the control group(72.50%),the difference was statistically significant(P<0.05).The HR and MAP of both groups decreased after administration(T1),1 min after intubation(T2),and 5 min after intubation(T3)compared to before administration(T0),and the HR of the combined group was lower than that of the control group,while the MAP was higher than that of the control group,the differences were statistically significant(P<0.05).The SpO2 at T1,T2 and T3 time points in the control group was significantly lower than T0 time point,the SpO2 of the combined group was higher than that of the control group at T1 and T2 time points,the differences were statistically significant(P<0.05);The Ramsay sedation score at T2 and T3 time points was lower than that of the control group,the difference was statistically significant(P<0.05).The total incidence of adverse reactions in the combined group(12.50%)showed no obvious difference compared to the control group(7.50%)(P>0.05).Conclusion The combination of midazolam and oxycodone has a good healing effect in fiberoptic bronchoscope intubation of burn patients with difficult airway,with a higher success rate of intubation,better sedation,and can maintain hemodynamic stability.It also has high medication safety.
