Objective: To explore the relationship between positive parenting styles and academic emotions in junior high school students, as well as the chain mediation effects of parent-child communication and peer relationships, providing a theoretical basis for family education interventions. Methods: Using stratified cluster random sampling, 1 063 students from four junior high schools in a city in Anhui Province were selected for questionnaire surveys, form March to April, 2025. Core variables were measured using the Short form Parenting Style Scale, Adolescent Parent-Child Communication Scale, Peer Relationship Scale, and Adolescent Academic Emotion Questionnaire. Group comparison was conducted using t-test or analysis of variance, and Pearson correlation analysis was used to examine the correlation between positive parenting styles, peer relationships, parent-child communication and positive academic emotions. Multiple linear regression analysis was used to examine the effects of positive parenting styles, peer relationships and parent-child communication on positive academic emotions. A mediation effect model and Bootstrap method were employed to test the chain mediation effects. Results: Students who were class leaders, had parents with higher education levels, or came from intact families scored significantly higher on positive academic emotions ( t/F =7.23, 13.73, 10.67, 4.45, all P < 0.01 ). Positive parenting styles, peer relationships, and parent-child communication were all positively correlated with positive academic emotions ( r =0.45, 0.41, 0.38), and all three positively predicted positive academic emotions ( β =0.24, 0.23, 0.12) (all P < 0.01 ). Further analysis showed that positive parenting styles directly predicted positive academic emotions ( β =0.40) and also indirectly influenced academic emotions through parent-child communication ( β =0.07), peer relationships ( β =0.05), and the chain mediation path of "parent-child communication → peer relationships" ( β =0.04) (all P <0.05), with the total indirect effect accounting for 40.55%. Conclusion Positive parenting styles enhance junior high school students academic emotions through the chain mediation path of "parent-child communication → peer relationships", providing theoretical support for interventions within the educational ecosystem.

OBJECTIVE To investigate the role and mechanism of paeonol in inhibiting the migration of bladder cancer T24 cells by regulating nuclear factor κB （NF-κB）/hypoxia-inducible factor-1α （HIF-1α）-mediated aerobic glycolysis. METHODS T24 cells were divided into control group， cisplatin group （positive control， 3.001 μg/mL）， and paeonol low-， medium- and high-dose groups （100， 200， 400 μg/mL）， respectively. After 24 h of administration intervention， the effect of paeonol on the migration ability of T24 cells was detected （expressed by the cell scratch wound healing rate）. The effect of paeonol on the mitochondrial membrane potential of T24 cells was detected （expressed by the ratio of red/green fluorescence intensity）. Cellular adenosine triphosphate （ATP） levels and lactate content in T24 cells were measured. The levels of NF-κB/HIF-1α signaling pathway， the expression of migration-related proteins， and key enzymes involved in aerobic glycolysis in the cells were all determined. RESULTS Compared with the control group， the cell scratch wound healing rates in the paeonol medium- and high-dose groups and the cisplatin group were decreased significantly （P＜0.01）； in the paeonol groups， the expression levels of NF-κB/HIF-1α signaling pathway-related proteins such as NF- κB and HIF-1α， migration-related proteins such as matrix metalloproteinase 2 （MMP2）， MMP9， and vascular endothelial growth factor， as well as key enzymes involved in aerobic glycolysis such as glucose transporter 1， hexokinase 2 and pyruvate kinase isozyme type M2， were all reduced to varying degrees in the cells， most of these reductions showed statistically significant differences （P＜0.05 or P＜0.01）； the ratio of red/green fluorescence intensity in mitochondria of cells in the medium- and high-dose paeonol groups were significantly decreased （P＜0.01）； the ATP concentration in cells of the paeonol high-dose group， and the lactate content in cells across all paeonol groups were significantly decreased （P＜0.05 or P＜0.01）. CONCLUSIONS Paeonol significantly inhibits the migration of bladder cancer T24 cells， and its mechanism of action may be related to the inhibition of the NF-κB/HIF-1α signaling pathway， and the down-regulation of key enzyme activities involved in aerobic glycolysis.

AIM: To investigate the decentration of the treatment zone(TZ)and the early impact on corneal higher-order aberrations(HOAs)induced by orthokeratology(OK)lenses fitted with digital corneal topography.METHODS: A retrospective longitudinal clinical study was conducted on 28 patients(28 right eyes)who were digitally fitted with OK lenses at the Laser Vision Center of Xi'an No.1 Hospital since 2023. Longitudinal measurements were taken at baseline, 1 wk, 1 and 3 mo post-treatment to assess changes in TZ diameter, decentration magnitude and direction. Furthermore, changes in corneal HOAs were observed, and correlations of decentration with each HOAs were also analyzed.RESULTS: The mean age of patients was 10.29±2.00 years, with 15 males and 13 females, and the average baseline spherical equivalent was -2.92±0.94 D. The average TZ diameters at 1 wk, 1, and 3 mo were 3.64±0.58, 3.83±0.57, and 3.69±0.55 mm, respectively, with no statistically significant differences between 1 wk and 3 mo. Horizontal decentration values were -0.43±0.28, -0.38±0.33, and -0.31±0.37 mm after wearing lenses for 1 wk, 1 and 3 mo, respectively, while vertical decentration values were -0.33±0.20, -0.33±0.23, and -0.36±0.23 mm across the same time points. The TZ consistently decentered inferotemporally, and changes in both horizontal and vertical decentration over time were not statistically significant(Fhorizontal=1.416, Phorizontal=0.252; Fvertical=0.126, Pvertical=0.882). Significant increases in total corneal HOAs, coma, and spherical aberration were observed at 5 mm optical zone post-wear(F=45.695, 33.401, and 45.091, all P<0.001). Vertical decentration at 1 wk and 1 mo was negatively correlated with total HOAs and coma(all P<0.05), while horizontal decentration at 3 mo showed a weak negative correlation with spherical aberration(P=0.037).CONCLUSION: Digitally-fitted OK lenses achieved stable TZ diameter by 1 wk post-wear, with minor inferotemporal decentration. Early post-wear corneal total HOAs, coma and sphercal aberration increased significantly, and vertical downward decentration was associated with elevated total HOAs and coma. However, correlations between decentration and HOAs weakened by 3 mo.

ObjectiveTo investigate the changes in the pathogen spectrum of viral diarrhea in local pediatric inpatients as well as any variations in genotypes of major pathogens during the COVID-19 control period. MethodsFecal samples were collected from the children <5 years who were hospitalized due to acute gastroenteritis in a pediatric hospital in Shanghai. PCR test was carried out to detect rotavirus， norovirus， sapovirus， astrovirus and enteric adenovirus， and then genotyping was performed for major pathogens. ResultsOut of 546 samples， 37.55% tested positive for virus with the following positive rate ranking： norovirus GⅡ （22.16%）， group A rotavirus （16.12%）， astrovirus （2.93%）， enteric adenovirus （2.38%）， sapovirus （0.92%） and norovirus GⅠ （0.18%）. The predominant genotype within norovirus GⅡ were GⅡ.4［P31］ and GⅡ.4［P16］ with a proportion of 24.79% and 14.05% respectively. The detection rate of GⅡ.4［P31］ dropped significantly over the 2-year period （χ²＝16.140，P<0.001）. In addition， an emerging rotavirus genotype G8P ［8］， which was rarely found nationally， was discovered for the first time locally with an increasing proportion， accounting for 7.95% of all rotavirus positive cases. Phylogenic analysis demonstrated that the representative strains of this genotype were genetically closer to the DS-1-like G8P ［8］ strain found in Southeast Asia. ConclusionThe changes in the prevalence of various norovirus genotypes together with the emergence of rare rotavirus genotype in the local area illustrate the importance of continuous monitoring of viral diarrhea and genotyping of key pathogens. Increased local activity of the rare genotype also adds new parameters in the efficacy evaluation of marketed vaccines and development of potential new vaccines in near future.

ObjectiveTo present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations， using COVID-19 infection as an example， and to provide a reference for improving the infectious disease surveillance and early warning system. MethodsA multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai， with households as the units. A cohort for acute infectious diseases based on natural community populations was established. The baseline survey was conducted for all cohort subjects， and COVID-19 antigen test kits were distributed. From December 21， 2022 to September 30， 2023， prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis. The baseline characteristics and follow-up information of the cohort subjects were described. ResultsThe cohort for acute infectious diseases included a total of 12 881 subjects， comprising 6 098 males （47.3%） and 6 783 females （52.7%）. The baseline survey revealed that 35.2% （4 540/12 881） of the subjects had a history of COVID-19 infection. During the follow-up period from December 21， 2022 to September 30， 2023， the average incidence density in the cohort was 0.61/person-year， with a higher incidence density in females （0.63/person-year） compared to males （0.59/person-year）. Individuals aged 60 and above （0.64/person-year） and those with underlying health conditions （0.67/person-year） had a higher incidence density. Healthcare workers showed a notably higher incidence density （0.84/person-year） than that in other occupational groups. As of September 30， 2023， a total of 340 subjects in the cohort experienced secondary infections， with a median interval of 170 days between the first and second infections. ConclusionThis study applies cohort study method to acute infectious disease surveillance， providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community. This method can be promoted and applied as a new approach for acute infectious disease surveillance.

Myopia is becoming more and more common all over the world, and the incidence of myopia is gradually increasing. Many treatments have been used to prevent and control myopia, including optics, drugs, environment or behavior, but the results are different and lack standardization. At present, many experiments have proved that peripheral defocus technology has a certain effect on myopia control. Based on this technology, three kinds of framed eyeglass lenses with peripheral defocus design, namely defocus incorporated multiple segments(DIMS), highly aspherical lenslets(HAL)and cylindrical annular reactive elements(CARE), are commonly used in medical and optometry institutions in China. These lenses provide not only clear vision in the central area, but also a certain amount of myopic defocus in the periphery to control the progression of myopia. This paper aims to focus on the design principle and myopia prevention and control effect of the above three peripheral defocus lenses, and evaluate their effectiveness in clinical practice.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Objective Under the background of"breaking the Five-Only"and the evaluation reform of healthcare professionals'titles,it analyzed the willingness of healthcare professionals in public hospitals to disseminate health knowledge and its incentives and constraints.Furthermore,it explored potential pathways to improve the willingness of healthcare professionals to popular science and disseminate health knowledge.Methods From November to Decem-ber 2022,a self-designed online questionnaire was used to survey healthcare professionals in four tertiary hospitals in Shanghai.The questionnaire included basic information of healthcare professionals,analysis of the current situa-tion and demands of healthcare professionals in health knowledge dissemination,willingness of healthcare profes-sionals to disseminate health knowledge and influencing factors.Results A total of 762 healthcare professionals partici-pated in this survey,79.9%(608/762)expressed willingness to promote the dissemination of health knowledge.A multiple-factor logistic regression analysis revealed that intermediate professional title,achieving personal value and so-cial responsibility,increasing patient resources,professional title promotion,science promotion-related awards,being included in performance appraisals,and difficulty in capturing science promotion skills were the influential factors affecting the dissemination of health knowledge among healthcare professionals(P＜0.05).Conclusion The willing-ness of healthcare professionals to disseminate health knowledge was strong,and hospitals should motivate health-care professionals to disseminate health knowledge through building a long-term incentive mechanism,strengthening training in science popularization ability,and improving humanistic qualities.

Objective:To understand the epidemiological characteristics of diarrheagenic Escherichia ( E. ) coli infection in infectious diarrhea outpatients aged 15 years and older in Shanghai and provide evidence for the development of disease control strategies .Methods:Based on multistage systematic sampling, diarrhea surveillance was conducted in 22 sentinel hospitals in Shanghai, the information about cases' demographic, clinical, and epidemiological characteristics were collected. Stool samples were collected for the detection and typing of diarrheagenic E. coli by local centers for disease control and prevention. The positive rate of diarrheagenic E. coli in different populations and seasons from 2014 to 2021 were analyzed. Statistical analysis was conducted by using χ2 test. Results:In 15 185 diarrhea cases, 8.05% (1 222/15 185) were positive for diarrheagenic E. coli. The positive rate was higher in men (8.74%, 684/7 824) than in women (7.31%, 538/7 361). The positive rate was highest in age group 15-29 years (9.14%, 335/3 665) and the annual positive rate was highest in 2021 (10.21%, 83/813), the differences were all significant ( P<0.05). In the 1 264 strains of diarrheagenic E. coli analyzed through PCR, enterotoxingenic E. coli was the most frequently identified pathogen (50.24%, 635/1 264), followed by enteroadhesive E. coli (27.93%, 353/1 264), and enteropathogenic E. coli (21.36%, 270/1 264). The positive rate of diarrheagenic E. coli showed obvious seasonality with peak in summer (13.92%, 774/5 562) ( χ2=495.73, P<0.001). Conclusions:Diarrheagenic E. coli has become a prominent pathogen in infectious diarrhea cases in Shanghai, the disease can occur all the year round with incidence peak during summer and autumn. Predominant subtypes included enterotoxingenic E. coli, enteroadhesive E. coli and enteropathogenic E. coli. Targeted prevention and control strategies are needed for diarrheagenic E. coli-induced infectious diarrhea in different age groups, seasons and for different types of infections.

Objective: To retrospectively analyze the epidemic characteristics and spatial distribution of vomiting and diarrhea outbreaks in schools and kindergartens in Shanghai from 2015 to 2019, so as to provide the scientific evidence for optimizing prevention and control of vomiting and diarrhea outbreaks in schools and kindergartens. Methods: Data collection and analysis were carried out on the vomiting and diarrhea outbreaks reported to Shanghai Municipal Center for Disease Control and Prevention from 2015 to 2019. Epidemiological characteristics were analyzed and compared. The proportion and incidence of outbreaks in schools and kindergartens were calculated, and the influencing factors of outbreaks were analyzed by multivariate Logistic regression. The index of Moran s I was used for the global and local spatial auto correlation analysis. Results: Among the 344 vomiting and diarrhea outbreaks, 98.26% occurred in kindergartens, primary schools, middle schools and other educational institutions. The median number of cases per outbreak was 15. The number of suspected outbreaks and the percentage of cases involved peaked in 2015 ( 60.00% , 84.35%) and then decreased year by year to 16.00% and 38.80% in 2019. About 86.98% of the outbreaks were transmitted by human to human contact. Among the 329 outbreaks with samples collected from cases and/or environments, the main pathogen detected was norovirus ( n =280), and sapovirus was detected in outbreak for the first time in 2016. The outbreaks showed obvious seasonality, with two peaks (November, March) and one trough (July), and the majority of outbreaks occurred in primary schools (44.38%) and kindergartens (32.84%). Compared with kindergartens, the probabilities of suspected epidemic outbreaks in primary schools, combined schools, middle schools and other educational institutions were higher (adjusted OR =6.40, 9.16, 12.64 , 5.58, P <0.01). The proportion and incidence of outbreaks in educational institutions in different districts showed no high-high aggregation areas. Conclusions Primary schools and kindergartens are key places for the prevention and control of vomiting and diarrhea outbreaks. Targeted prevention and control measures should be strengthened at the beginning of each semester and before the peak of the epidemic each year. Timely reporting of symptoms, suspension of school admissions after symptoms appear and standardized disposal of vomit are effective measures to reduce interpersonal transmission and control the scale of an outbreak.
