Objective: To evaluate the intervention effect of school based salt reduction health education, so as to provide a scientific basis for constructing a more effective and sustainable salt reduction intervention model for children. Methods: According to a randomized controlled trial design, in June 2022, probability proportional to size sampling was used to select 501 second grade students (248 in the control group and 253 in the intervention group) from 10 primary schools in Zhenjiang (intervention group) and 10 primary schools in Yangzhou (control group), Jiangsu Province. An one year school based salt reduction health education intervention was implemented. This included 20 online and 8 offline health education sessions, monitoring of salt consumption in the canteen, and the establishment of a salt reduction environment on campus. The control group received no additional salt reduction interventions. A questionnaire survey and 24 hour urinary sodium test were conducted before and after the intervention. The difference in differences method was used to evaluate the intervention effect. Results: After the intervention, the intervention group showed significant net intervention effects in knowledge aspects, including knowing that primary school students consume less salt than adults ( OR=3.55,95%CI =1.69-7.47), daily salt intake of primary school students ( OR=6.64,95%CI =3.71-11.87), long term high salt intake leading to hypertension ( OR=6.83,95%CI =3.93-11.91), low salt intake not causing hair graying ( OR= 1.66 ,95%CI =1.00-2.75), salt content in food labels ( OR=4.56,95%CI =2.63-7.91), and common high salt foods ( OR=3.39,95%CI =1.87-6.14) (all P <0.05). In terms of attitude, the net intervention effect for having a positive attitude toward using less salt in home cooking was significantly increased ( OR=1.88,95%CI =1.13-3.12, P <0.05). There were no statistically significant net intervention effects for salt reduction related behaviors (all P >0.05). There was no statistically significant difference in the changes of 24 hour urinary sodium between the intervention group and the control group before and after intervention ( P >0.05). Conclusions School based salt reduction health education effectively improves students salt reduction knowledge and attitudes but has a limited effect on behavior change. The home-school collaboration should be strengthened, and the dietary environment should be optimized simultaneously.

Foot-and-mouth disease (FMD) is one of the major animal infectious diseases in the world. All cloven-hoofed animals are susceptible to FMD. Vaccination is still the first choice for the prevention and control of FMD. mRNA vaccines can be rapidly designed, synthesized, and produced on a large scale in vitro, and they can induce effective protective immune responses, demonstrating the advantages of rapid development, easy preparation, and low biosafety risks. The design of untranslated regions is a key to enhancing the expression and efficacy of mRNA vaccines. In order to generate an efficient FMD mRNA vaccine, we designed three FMD P12A3C expression vectors with different untranslated regions and synthesized corresponding mRNAs. By comparing expression efficiency of these vectors and their mRNAs at different time points and in different cell lines, we found that the mRNA P12A3C-UTR3 had the best expression and universality. This study laid a foundation for the development of mRNA vaccines against FMD and provided a theoretical basis for the optimal sequence design of efficient mRNA.

Objective To investigate the clinical efficacy and safety of modified single-port thoracoscopic sympathectomy combined with disconnection ventilation in the treatment of primary palmar hyperhidrosis(PPH).Methods The perioperative indexes,clinical efficacy and postoperative complications of 20 patients with PPH who underwent modified single-port thoracoscopic sympathectomy combined with disconnection ventilation in Wuming Hospital of Guangxi Medical University from June 2020 to July 2024 were retrospectively analyzed.Results All patients successfully completed the operation without serious complications and death.The average operation time was(56.15±16.00)min,and the average intraoperative blood loss was(3.35±1.39)ml.The treatment effective rate was 100%,the average postoperative hospitalization time was(2.15±0.86)days,and the average hospitalization cost was(9485.56±1601.77)yuan.During the follow-up period of 1 to 45 months,there were no recurrent cases and no obvious cases of compensatory hyperhidrosis.Conclusion The modified single-port thoracoscopic sympathectomy combined with disconnection ventilation has good efficacy and safety in the treatment of PPH.

Li-Fraumeni syndrome(LFS)is a rare autosomal dominant genetic disorder.Patients with LFS tend to develop tumors at a young age and are at risk of multiple types of cancer.The core pathogenic mechanism of LFS is germline mutation of the TP53 gene,which leads to loss of function of the p53 protein and an increase in the risk of tumor development.There are many tumor types closely related to LFS,including soft tissue sarcoma,osteosarcoma,brain tumors,breast cancer,and adrenocortical carcinoma.Although some common mutation sites of the TP53 gene in LFS patients have been identified,there are still differences in mutation sites among different patients,and the type of TP53 gene mutation may affect the clinical manifestations and prognosis of patients.Therefore,genetic testing for LFS patients to determine the specific mutation form of TP53 is of great significance.This article reviews the clinical patho-logical characteristics,treatment methods,and prognosis of LFS-related tumor patients,aiming to provide useful refer-ences for clinical practice.

Purpose To investigate the differential expression of proteins secreted by diffuse-type gastric cancer-associated fibroblasts(DGC-CAFs)and intestinal-type gastric cancer-associated fibroblasts(IGC-CAFs)according to Lauren classification of gastric cancer.Methods Fresh surgery samples were acquired to extract primary cancer-asso-ciated fibroblasts(CAFs)to obtain the conditional medium,including three cases of diffuse-type gastric cancer(DGC)and three cases of intestinal-type gastric cancer(IGC).Then high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)was used to detect the differences in secreted factors between DGC-CAFs and IGC-CAFs.Additionally,a total of 1 174 cases were collected from the GEO and TCGA databases,and the distribution of stromal cells was assessed via ESTIMATE to derive stromal scores for both DGC and GC.Furthermore,Kaplan-Meier survival analysis was performed to evaluate the relationship between high stromal scores,elevated CAFs proportions,and patient prognosis.Subsequently,GO enrichment analysis was performed to investigate associated genes and their bi-ological functions.Results HPLC-MS/MS analysis showed that only 10 proteins were identified to be expressed in both DGC-CAFs and IGC-CAFs,namely SPARC,COL6A1,COL1A2,COL1A1,COL3A1,FN1,DCN,ACTG1,TIMP1 and SHROOM3.There were 8 proteins expressed higher in DGC-CAFs than IGC-CAFs in all cases with ratio＞2,namely COL3A1(5.28),COL1A2(3.98),DCN(3.71),TIMP1(3.40),COL6A1(3.35),ACTG1(3.13),COL1A1(2.84)and SHROOM3(2.50).Two other proteins,TUBB and BASP1,were identified in all three cases of DGC-CAFs.The former was only identified in one case of IGC-CAFs,while the latter was not identified in all three cases of IGC-CAFs.The results of bioinformatics analysis showed that the stromal score of DGC was higher than IGC,which correlated with poor prognosis.Analysis of cell components revealed that the related genes were more enriched in ECM,collagen-containing extracellular matrix and cell-cell junction.Also,the biological process and molecular function was based on the components,which was consistent with HPLC-MS/MS analysis results.Conclusion There are differ-ences in secreted proteins of DGC-CAFs and IGC-CAFs,both on the types and the content.The differential proteins are mostly enriched in ECM-related signaling pathways.Presumably,the high content of CAFs in the stroma affects the prognosis of gastric cancer patients by influencing the gene expression and the function of receptor pathway of ECM.
