Objective: To investigate the epidemiological characteristics of spinal curvature abnormalities among primary and secondary school students in Henan Province, and to explore their association with classroom environment, so as to provide scientific evidence for targeted prevention and control strategies. Methods: From September to October 2025, 751 schools from 158 counties/districts in Henan Province were chosen by using a stratified random cluster sampling technique. A total of 4 019 classrooms were monitored and physical examinations for 202 293 students were conducted. By matching classroom environment monitoring data with student physical examination information, Chi square test and Chi square test for trend were used for between group comparisons, and a multilevel Logistic regression model was used to analyze the association between classroom environment and spinal curvature abnormalities among primary and secondary school students. Results: The detection rate of spinal curvature abnormalities among primary and secondary school students in Henan Province was 2.48% in 2025. The rate was higher in girls ( 2.65 %) compared to boys (2.32%), higher in urban students (3.23%) compared to rural students (2.01%), and higher in wasted students (3.89%) compared to non wasted students (2.39%); all differences were statistically significant ( χ 2=22.92, 298.34 , 100.84, all P <0.05). Age and school stage were associated with an increasing trend in the detection rate of spinal curvature abnormalities ( χ 2 trend = 1 494.46 , 1 430.79, both P <0.05). After controlling for confounding variables like residence area, sex, and age, multilevel Logistic regression analysis revealed that non compliance with desk-chair fit standards ( OR=1.47, 95%CI = 1.22-1.78), blackboard reflectance ( OR=1.18, 95%CI =1.06-1.33), and blackboard size ( OR =1.37, 95% CI =1.21-1.55) increased the risk of spinal curvature abnormalities among primary and secondary school students (all P <0.01). Conclusions There are population based differences in spinal curvature abnormalities among primary and secondary school students in Henan Province. The occurrence is strongly correlated with elements of the teaching environment. It is necessary to put in place comprehensive preventative and control strategies that focus on pertinent environmental elements.

Objective: To investigate the prevalence and correlates of five somatic symptoms among junior and senior high school students, so as to provide a reference for the prevention of these symptoms in the population. Methods: From September to November 2024, a stratified cluster random sampling method was used to select 163 802 junior and senior high school students from 158 counties/districts in Henan Province. A questionnaire survey was conducted using the Student Health Status and Influencing Factors Survey (Secondary School Version) and the Special Survey on Influencing Factors of Key Common Diseases. Logistic regression was used to analyze the factors associated with each of the five somatic symptoms. Results: The reported prevalence of fever, cough, sore throat, diarrhea, and vomiting were 7.93%, 23.56%, 13.67%, 18.03%, and 3.17%, respectively. Girls reported (8.20%, 25.26%, 16.54%, 19.14%, 3.68%) higher rates than boys (7.67%, 21.97%, 11.00%, 16.99%, 2.69%) ( χ 2= 16.01, 245.78, 1 063.22, 128.89, 129.48, all P <0.01). Boarding students (8.95%, 25.79%, 15.77%, 20.77%, 3.45%) also had higher rates than nonboarding students (6.63%, 20.75%, 11.02%, 14.56%, 2.80%)( χ 2=298.37, 569.43, 772.23, 1 055.42 , 55.82, all P <0.01). Students from nonintact families reported higher rates (8.87%, 24.89%, 14.57%, 19.20%, 3.60% ) than those from intact families (7.58%, 23.07%, 13.34%, 17.60%, 3.01%) ( χ 2=72.48, 58.98, 41.61, 55.40, 36.00, all P <0.01). After adjusting for sociodemographic variables, multivariate Logistic regression showed that unhealthy dietary habits, daily homework or tutoring duration≥2 hours, daily screen time ≥2 hours, lack of parental encouragement for exercise, exposure to tobacco/alcohol, and substance abuse were associated with increased risk of reporting the five somatic symptoms ( OR =1.27- 1.63 , 1.21-1.27, 1.28-1.40, 1.07-1.13, 1.77-2.08, 1.76-2.17, all P <0.05). Conversely, handwashing habits, twice daily tooth brushing, daily breakfast consumption, engaging in at least 60 minutes of moderate to vigorous physical activity per day, spending outdoor time during breaks, and adequate sleep were associated with lower risk ( OR =0.82-0.90, 0.85 -0.92, 0.44- 0.76 , 0.83-0.93, 0.69-0.75, 0.65-0.78, all P <0.05). Conclusions Disparities exist in the prevalence of fever, cough, sore throat, diarrhea, and vomiting among secondary school students in Henan Province. The risk of experiencing these five somatic symptoms is closely linked to daily health behaviors. Comprehensive intervention strategies and scientific measures should be implemented to prevent somatic symptoms in junior and senior high school students.

Objective:To investigate the mosquito-borne viruses carried by mosquito specimens collected from Huachuan county and Huanan county in Heilongjiang province.Methods:Mosquito samples were collected locally in 2023 and processed in the laboratory. Homogenates of the mosquitoes were inoculated into cells for virus isolation, followed by molecular and bioinformatics analyses of the viral isolates.Results:In 2023, ten viral isolates were obtained from Anopheles sinensis specimens collected in Heilongjiang province, China. Among these isolates, one was identified as Culex flavivirus (CxFV), one as Menghai rhabdovirus (MRV), and eight as Nam Dinh virus (NDiV). The phylogenetic analysis showed that CxFV belongs to genotype I and is clustered with the strains isolated from Liaoning province in 2011 and Ningxia Hui autonomous Region in 2019 in the same evolutionary branch, with amino acid similarity ranging from 98.2% to 99.2% and nucleotide similarity ranging from 98.8% to 99.2%. The MRV strain belongs to the same evolutionary subclade as the strain detected in Guangdong, with both nucleotide and amino acid similarity of 98.0%. Eight NDiV isolates clustered with the South Korean isolates on the same evolutionary branch, forming an independent evolutionary sub-branch. The nucleotide similarity among these eight isolates ranged from 98.5% to 99.7%, while the amino acid similarity ranged from 98.1% to 99.7%. In comparison, when matched with other NDiV isolates from China, the nucleotide similarity of these eight isolates ranged from 94.1% to 97.8%, and the amino acid similarity ranged from 93.5% to 97.7%.Conclusions:This study represents the first isolation of CxFV, MRV, and NDiV in Heilongjiang province, China, and the findings provide fundamental data for the prevention and control of mosquito-borne viral diseases in this region.

Objective:To evaluate the efficacy and safety of high-frequency repetitive transcranial magnetic stimulation (hrTMS) in postherpetic neuralgia (PHN).Methods:A prospective randomized controlled trial was performed; 63 PHN patients treated in Department of Neurology and Department of Dermatology and Venereology of Anqing Municipal Hospital from June 2024 to March 2025 were enrolled; they were randomly assigned to 2 groups: an hrTMS group ( n=32) received hrTMS (frequency: 10 Hz; total pulses: 2,400; intensity: 90% of resting motor threshold) to the contralateral primary motor cortex (M1), and a sham stimulation group ( n=31) received sham stimulation using a sham figure-of-eight coil generating no actual magnetic field. Scores of short-form McGill pain questionnaires (pain rating index [PRI] total score, PRI sensory subscore, PRI affective subscore, visual analogue scale [VAS] score, present pain intensity [PPI] score) and N100 amplitude were collected before treatment and at 1, 2, 3, and 4 weeks after treatment. Adverse events during treatment were recorded. Results:At 2 weeks after treatment, significant difference was observed between the hrTMS group and sham stimulation group in PRI total score, VAS score, and N100 amplitude ( P<0.05). At 3 and 4 weeks after treatment, significant differences were found between the two groups in PRI total score, PRI sensory subscore, PRI affective subscore, VAS score, PPI score and N100 amplitude (3 weeks after treatment: 8.59±1.13 vs. 9.61±1.20, 5.34±0.79 vs. 5.90±0.94, 3.25±0.57 vs. 3.71±0.46, 5.78±0.66 vs. 6.42±0.92, 2.16±0.37 vs. 2.55±0.51, and [2.53±0.51] μV vs. [2.13±0.34] μV; 4 weeks after treatment: 7.53±0.92 vs. 9.68±1.35, 4.94±0.62 vs. 6.00±1.07, 2.59±0.56 vs. 3.68±0.60, 5.06±0.67 vs. 6.23±1.06, 1.97±0.17 vs. 2.52±0.51, and [2.81±0.40] μV vs. [2.16±0.52] μV, P<0.05). In the hrTMS group, PRI total score, PRI sensory subscore, PRI affective subscore, VAS score, PPI score and N100 amplitude were significantly different at 2, 3, and 4 weeks after treatment compared with those before treatment ( P<0.05). Incidence of adverse events (headache, dizziness or tinnitus) did not differ significantly between the two groups ( P>0.05). Conclusion:The hrTMS applied to the M1 region in PHN patients is effective by obviously reducing pain intensity and improving negative emotional states, with favorable safety profile.

Objective:To characterize the etiological and genetic features of pediatric influenza outbreaks in Changzhou between 2021 and 2024，with the goal of informing evidence-based prevention strategies and guiding effective management of influenza outbreaks in school settings.Methods:During the period of 2021 to 2024，throat swabs of influenza-like cases from school outbreaks in Changzhou were collected. These samples underwent real-time reverse transcription-polymerase chain reaction（RT-PCR）testing and virus isolation. Epidemiological data were integrated to conduct pathogenetic analysis. The HA genes of isolated strains were amplified and sequenced to perform genetic characterization.Results:Between 2021 and 2024，a total of 256 influenza outbreaks were reported in schools in Changzhou. A total of 3 201 specimens were collected，of which 2 245 were tested positive for influenza viruses，resulting in a positivity rate of 70.13%. The outbreak season was primarily concentrated from December to February each year，with settings predominantly distributed in primary schools（accounting for 73.83%）. The predominant epidemic strains were influenza A viruses，including 118 outbreaks caused by H1N1 and 104 by H3N2. A total of 74 influenza virus strains were successfully isolated from positive specimens，and sequencing of the hemagglutinin（HA）gene was completed. Phylogenetic analysis revealed that certain B/Victoria lineage strains（e.g.，B/Changzhou/01/2021）clustered closely with the vaccine strain B/Austria/3594/17（bootstrap support：99%）. Among influenza H1N1 strains，multiple isolates from 2023—2024 clustered within the same major branch as A/Victoria/4897/2022（bootstrap support：100%）. In contrast，the H3N2 strains exhibited a complex evolutionary pattern，showing variable genetic distances to vaccine strains from different years（e.g.，A/Massachusetts/18/2022，A/Darwin/6/2021）；some isolates were closely related to vaccine strains，while others were more distantly related and scattered across the phylogenetic tree.Conclusions:The influenza outbreak situation in schools was severe and has significant public health implications. Continuous surveillance is essential，and preventive strategies should be promptly adjusted based on the epidemiological and genetic characteristics of circulating strains.
