Objective: To evaluate the effect of weight monitoring feedback intervention among primary school students, so as to provide the evidence for strengthening children's weight management. Methods: In October 2023, students from grades four to six in a primary school in Hangzhou City were selected and randomly assigned to a control group and an intervention group on a class-by-class basis. The included primary school students had their height and weight measured at a fixed time each week, and the results were fed back to their parents in the form of cards. The cards for the control group contained knowledge about healthy lifestyles, while those for the intervention group additionally included information on body mass index (BMI), BMI grouping, and BMI ranking. Overweight and obesity were determined according to the age- and gender-specific criteria in the Screening for Overweight and Obesity among School-aged Children and Adolescents. After a 9-month intervention period, the prevalence rates of overweight and obesity and lifestyle behavior data between the two groups before and after the intervention were compared by a generalized linear mixed model, in order to assess the effectiveness of the weight monitoring information feedback intervention. Results: The intervention group consisted of 368 students, including 208 boys (56.52%) and 160 girls (43.48%). The majority of students were 11 years, with 153 students accounting for 41.58%. The prevalence rate of overweight and obesity was 24.18%. The control group had 324 students, with 180 boys (55.56%) and 144 girls (44.44%). The predominant age was also 11 years, with 128 students accounting for 39.51%. The prevalence rate of overweight and obesity was 25.31%. Before the intervention, there were no statistically significant differences between the two groups in terms of gender, age, prevalence rate of overweight and obesity, eating habits, exercise situation, and sleep patterns (all P>0.05). After the intervention, there were significant interactions between group and time for the prevalence rate of overweight and obesity, the frequency of moderate-intensity exercise per week, and adequate sleep in the two groups (all P<0.05). The prevalence rate of overweight and obesity in the intervention group (OR=0.461, 95%CI: 0.252-0.845) was lower than that in the control group. The proportions of students in the intervention group who engaged in moderate-intensity exercise ≥4 times per week (OR=1.315, 95%CI: 1.033-1.675) and had adequate sleep (OR=1.402, 95%CI: 1.049-1.875) were higher than those in the control group. Conclusion Weight monitoring feedback can reduce the incidence of overweight and obesity among primary school students and has a certain improving effect on lifestyle behaviors such as exercise and sleep.

Epilepsy is a chronic neurological disorder affecting ~65 million individuals worldwide. Abnormal synaptic plasticity is one of the most important pathological features of this condition. We investigated how ubiquitin-specific peptidase 47 (USP47) influences synaptic plasticity and its link to epilepsy. We found that USP47 enhanced excitatory postsynaptic transmission and increased the density of total dendritic spines and the proportion of mature dendritic spines. Furthermore, USP47 inhibited the degradation of the ubiquitinated α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) subunit glutamate receptor 1 (GluR1), which is associated with synaptic plasticity. In addition, elevated levels of USP47 were found in epileptic mice, and USP47 knockdown reduced the frequency and duration of seizure-like events and alleviated epileptic seizures. To summarize, we present a new mechanism whereby USP47 regulates excitatory postsynaptic plasticity through the inhibition of ubiquitinated GluR1 degradation. Modulating USP47 may offer a potential approach for controlling seizures and modifying disease progression in future therapeutic strategies.

Health communication is the most core element in health education and health promotion.This paper summarizes and analyzes the research in China related to the evaluation of health communication effects through different media.It finds that the current evaluation indicators of communication effects are generally focused on changes in awareness rates.Traditional media and new media,as different types of communication mediums with their own advatages and limitations,do not have unified indicators to scientifically evaluate their communication effects in China,Due to the interdisciplinary nature of health communication,qualitative research methods(such as the Delphi method)have not been fully applied by researchers in the field of public health in China.This paper aims to sort out and compare various effects evaluation indicatorsof health communication with different media from current research through a literature review,and to provide evidences for improving a comprehensive and practical effect evaluation system of health communication in the future.

AIM:To investigate the effects of γ-synuclein on autophagy and apoptosis of colon cancer cells in-duced by endoplasmic reticulum stress,as well as the protective effect on the cells.METHODS:Gene expression profile chip analysis was performed to compare the cDNA expression profiles between human colon cancer HCT116 cells with γ-synu-clein knockdown and HCT116 cells with control siRNA,and to identify potential molecules related to autophagy and apop-tosis.In colon cancer cell lines,the functional effects of γ-synuclein on autophagy and apoptosis induced by thapsigargin(TG),an endoplasmic reticulum stress-inducing agent,were systematically explored by conducting immunofluorescence staining,Western blot,CCK-8 assay,flow cytometry,and transmission electron microscopy.Western blot was used to de-tect the expression of γ-synuclein protein,autophagy-related proteins[microtubule-associated protein 1 light chain 3(LC3),beclin-1,autophagy-related protein 5(ATG5)and ATG7],and apoptosis-related proteins[poly(ADP-ribose)polymerase(PARP),pro-caspase-3,and pro-caspase-9].To further analyze the mechanism of γ-synuclein in regulating autophagy and apoptosis,extracellular signal-regulated kinase(ERK)inhibitor PD98059,ERK inhibitor SP600125 and c-Jun N-terminal kinase(JNK)activator anisomycin were applied separately to test HCT116 cells transfected with γ-synu-clein siRNA.Subsequently,autophagy proteins,apoptosis proteins,and ERK and JNK pathway-related proteins were de-tected by Western blot.RESULTS:The TG-induced autophagy of colon cancer cells mainly occurred at the early stage(0～24 h),and apoptosis mainly occurred at the late stage(36～48 h).Endoplasmic reticulum stress up-regulated the ex-pression of γ-synuclein in colon cancer cells,which was associated with enhanced autophagy.γ-Synuclein promoted au-tophagy by activating ERK and JNK pathways at the early stage(0～24 h),and inhibited apoptosis by blocking JNK path-ways at the late stage(24～48 h)to protect HCT116 cells.In our model,γ-synuclein was observed to play a critical role in the transition from endoplasmic reticulum stress-induced autophagy to apoptosis.CONCLUSION:In the context of endo-plasmic reticulum stress,γ-synuclein promotes autophagy and inhibits apoptosis by regulating ERK and JNK signaling pathways,thus protecting colon cancer cells.This provides a potential idea for anti-tumor therapy.

Objective:To investigate the efficacy and safety of dual wavelength pulsed dye laser combined with 30% supramolecular salicylic acid in the treatment of moderate and severe facial acne.Methods:Sixty patients with moderate and severe acne that visited the Dermatology Department of the First Affiliated Hospital of Chongqing Medical University from May 2020 to January 2021, were selected and randomly divided into observation group and control group, with 30 patients in each group. The observation group was given dual-wavelength pulsed dye laser combined with 30% supramolecular salicylic acid. 30% supramolecular salicylic acid was used once every two weeks, for a total of six times. Dual-wavelength pulsed dye laser was given once a month, for a total of three times. The control group was only given dual-wavelength pulsed dye laser, once a month, a total of three times.Results:Twenty-two cases (73.33%) in the observation group were effective, while 14 cases (46.67%) in the control group were effective. The efficacy of the observation group was better than that of the control group, and the difference was statistically significant (χ 2=4.44, P<0.05). There were no obvious adverse reactions in both groups. Conclusions:Dual-wavelength pulsed dye laser combined with 30% supramolecular salicylic acid is effective and safe in the treatment of moderate and severe facial acne, which is worth popularizing.

Objective: To analyze knowledge, attitudes and practice regarding protection against COVID-19 among primary and middle school students in Hangzhou and to provide a scientific basis for schools to carry out targeted prevention and control measures. Methods: Anonymous network sampling survey was carried out through the questionnaire star, and a total of 14 216 subjects from primary and middle school in Hangzhou were recruited to fill in the questionnaire regarding knowledge, attitudes and practice of COVID-19 from March 3 to March 7, 2020. Results: Primary and middle school students showed high awareness rate of transmission (85.83%) and incubation period (77.44%), but lower awareness on symptoms (44.70%) of COVID-19. The practice of wearing masks, cough etiquette and correct hand washing were 97.27%, 88.01% and 91.82%, respectively. The protective practice among primary and middle school students were generally good, 91.21% of them were at moderate level or above. 83.91% of primary and secondary school students reported worries about infection of COVID-19, and 55.42% of primary and secondary school students were anxious about returning to school. Primary school students and rural students were more anxious about returning to school(χ 2=46.66, 26.70, P<0.05). Conclusion The primary and middle school students in Hangzhou have a relatively good level of knowledge and practice concerning COVID-19. Yet, it is necessary to carry out targeted health education and strengthen mental health education for primary and middle school students.

Objective: To understand the changing trend and influencing factors of health literacy among residents in Hangzhou from 2016 to 2020, so as to provide basis for health literacy promotion. Methods: The monitoring data of health literacy of residents in Hangzhou from 2016 to 2020 were collected. The five year cumulative growth and average growth rate were used to reflect the changing trend. The multivariate logistic regression model under complex survey design was used to analyze the influencing factors for health literacy. Results: From 2016 to 2020, the health literacy levels of Hangzhou residents were 26.91%, 29.49%, 31.83%, 34.73% and 38.00%, respectively. The five year cumulative growth was 11.09% and the average growth rate was 9.01%. Among three aspects of health literacy, the levels of basic knowledge and concept as well as healthy lifestyle and behaviors increased year by year (P<0.05), with the average growth rates of 15.12% and 2.92%. Among six types of health problems, the levels of chronic disease prevention and treatment, basic medical treatment, scientific view, health information as well as safety and first aid increased year by year ( P<0.05 ), with the average growth rates of 32.76%, 15.82%, 8.41%, 7.12% and 1.53%, respectively. The multivariate logistic regression analysis showed that education level ( junior high school, OR=5.359, 95%CI: 1.151-24.953;high school/vocational high school/technical secondary school, OR=9.214, 95%CI: 2.906-29.213; college or above, OR=29.977, 95%CI: 9.689-92.741 ) and occupation ( students, OR=2.564, 95%CI: 1.113-5.907 ) were the influencing factors for health literacy. Conclusion The health literacy levels of Hangzhou residents from 2016 to 2020 have been increasing year by year. The residents with higher education levels and students may have higher health literacy levels.
