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.

This article reports two cases of proteinuria caused by anti-vascular endothelial growth factor (VEGF) drugs in the treatment of liver cancer and ovarian cancer, respectively. Hypertension, massive albuminuria and renal insufficiency occurred in the patient with liver cancer during the use of toripalimab/camrelizumab combined with lenvatinib and regorafenib, and urinary protein was 4.02 g/24 h. The patient with ovarian cancer developed hypertension, proteinuria and 1.13 g/24 h urinary protein during the use of bevacizumab. Renal biopsy showed thrombotic microangiopathy in the glomeruli of both patients. Anti-VEGF drugs-associated glomerular microangiopathy was considered. The patient with liver cancer had no improvement after halving the dose of lenvatinib, and the effect was not good after treatment with low-dose corticosteroids combined with renin-angiotensin-aldosterone system inhibitors. After stopping anti-VEGF drugs, the proteinuria in both patients turned negative.

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.

Objective To investigate the expression of microRNA-134 ( miR-134 ) , CREB and pCREB in the temporal lobe tissue of patients and epileptic rats and to explore their roles in pathogenesis of epilepsy.Methods Tempo-ral lobe tissue samples of 14 patients with refractory epilepsy and 10 non-epileptic patients, and hippocampus and brain tis-sue samples of 42 rats were used in this study.Forty-two healthy adult male Sprague-Dawley rats were randomly divided in-to 6 epilepsy groups (24 h, 72 h, 7 d, 14 d, 30 d, and 60 d after kindling epilepsy) and a normal control group (n=6 for all groups) .The rat model of epilepsy was generated by intraperitoneal injection of 127 mg/kg lithium chloride and 16-20 h later, 35 mg/kg pilocarpine.In the temporal lobe tissue of patients and hippocampal tissue of rats, the expression level of miR-134 was detected by real-time polymerase chain reaction.The expression levels of CREB and pCREB were de-termined by Western blot, and CREB and pCREB localization was assessed by immunohistochemistry.Results Compared with the control rats, the expression of miR-134 was significantly decreased in the temporal lobe tissue of experimental rats at 72 h,7 d,14 d, 60 d after kindling (P<0.05),and no significant change at 24 h and 30 d after kindling (P>0.05). Expression of miR-134 in patients with refractory epilepsy was significantly lower than that of the controls ( P<0.05 ) , while up-regulation of CREB expression was at the same time points (P<0.05).Up-regulation of pCREB expression was at all the time points after kindling (P<0.05).CREB and p-CREB expressions were seen in the nuclei of neurons, and significantly higher in patients with refractory epilepsy and epileptic rats.Conclusions The expression of miR-134 is sig-nificantly decreased and that of CREB and pCREB was significantly increased in the temporal lobe tissue of patients with re-fractory epilepsy and the hippocampal tissue of epileptic rats.These findings indicate that the signaling pathway of miR-134/CREB/pCREB may play an important role in the pathogenesis of epilepsy.

When we try to establish the gene recombinant yeast cell to screen the androgenic endocrine disruptors, the key procedure is the androgen receptor (AR) expression in the yeast cell. For this purpose, we obtained the GPD (glyceraldehyde-3-phosphote dehydrogenase) promoter from the yeast genosome of W303-1A using PCR system and inserting it into Swa I and BamH I sites of pYestrp2. The new constructed vector was named pGPD. The V5 epitope tag DNA with a 5'-BamH I and a 3'-EcoR I sticky end was cloned into the corresponding site of the pGPD vector to yield the vector of pGPDV5. The 2 723 bp full length AR ORF amplified by PCR from pcDNA3.1/AR was fused to V5 epitope tag DNA in pGPDV5 to give the AR yeast expression vector of pGPDV5/AR. This fused vector was transformed into the yeast cell (W303-1A). Western blot was used to detect the V5 fused protein of AR, in the protocol of which the primary monoclonal antibody (IgG(2a)) of mouse anti-V5 and the polyclonal secondary antibody of goat anti-mouse (IgG) linked to horseradish peroxidase (HRP) were used to detect the specific protein in the given sample of the transformed yeast extract. The result showed that the fused protein of AR was expressed successfully in the yeast cell.
