ObjectiveTo assess the level of health literacy and its influencing factors among middle school students aged 12‒18 years in Jing’an District, Shanghai, so as to provide a solid scientific foundation for further developing more targeted intervention measures. MethodsA stratified cluster random sampling method was used to randomly select 4 middle schools in Jing’an District, Shanghai from November to December 2023, and conducted a health literacy questionnaire survey on non-graduating middle and high school students, respectively. The2023 Survey on the Status of Health Literacy among Middle School Students in Jing’an District, Shanghai was adopted, which consisted of two parts: health literacy and basic information. Health literacy was divided into three dimensions: health knowledge and concept literacy, healthy lifestyle and behavior literacy, and health skill literacy. Three dimensions could be categorized into six types of health literacy issue: scientific health literacy, infectious disease prevention and control literacy, chronic disease prevention and control literacy, safety and first aid literacy, basic health literacy, and health information literacy. ResultsA total of 1 161 middle school students were enrolled into this study, including 571 males and 570 females. The overall health literacy level of middle school students was 33.51%, with 34.81% among middle school students and 31.69% among high school students, respectively. Results of logistic regression analysis showed that health knowledge acquisition and awareness, as well as application frequency of health knowledge, were the influencing factors for the overall health literacy level among middle school students (P<0.05). The degree of family attention to health maintenance, health knowledge acquisition and awareness, and application frequency of health knowledge were the main influencing factors for the three dimensions and literacy of six types of health issues among middle school students (P<0.05). ConclusionThe levels of different types of health literacy among middle school students in Jing’an District are uneven, with the highest being safety and first aid literacy and the lowest being basic health literacy. It is recommended to take targeted measures to comprehensively improve the health literacy level of middle school students.

OBJECTIVE To explore the potential mechanism of Cigu Xiaozhi Prescription(CGXP)in the treatment of non-alco-holic steatohepatitis(NASH)liver fibrosis.METHODS A NASH mouse model was established.The degree of liver enlargement was evaluated by calculating the liver index.Hematoxylin-eosin(HE)and Masson staining were used to observe the degree of liver fibro-sis.In addition,immunohistochemistry was employed to detect the expression of liver fibrosis-related proteins,including α-SMA,Collagen 1,MMP2,and MMP9.Western blot and qPCR techniques were used to detect the expression levels of HIF-1α,E-cadher-in,N-cadherin,Shh,Smo,Gli1,and Gli2 in the mouse liver.The alkaline hydrolysis method was used to measure the content of liv-er hydroxyproline.RESULTS CGXP could effectively reduce the liver index(P<0.001),alleviate liver enlargement and inflamma-tion,and significantly improve the pathological damage of liver tissue in mice with liver fibrosis.CGXP significantly decreased the ex-pression levels of liver fibrosis-related proteins α-SMA,Collagen 1,MMP2 and MMP9(P<0.01,P<0.000 1);reduced the levels of HIF-1α,E-cadherin,N-cadherin,Shh,Smo,Gli1,and Gli2,and the therapeutic effect of high-dose CGXP was particularly significant(P<0.05,P<0.01,P<0.001,P<0.000 1).CONCLUSION CGXP can relieve NASH liver fibrosis in mice by reducing the liver index,alleviating inflammation,and improving tissue pathological damage.The mechanism may be related to the inhibition of the Hedgehog signaling pathway,which alters the activation and proliferation of hepatic stellate cells and reduces the synthesis and dep-osition of extracellular matrix.

Objective:To explore the mechanisms of oxaliplatin resistance mediated by TET2 methylation in the treatment of acute lymphoblastic leukemia (ALL) using bioinformatics methods.Methods:The data on drug-resistant and sensitive cell lines related to oxaliplatin treatment for ALL were download using the Genomics of Drug Sensitivity in Cancer (GDSC) database (updated in December 2023); the drug-resistant cell lines were screened based on half maximal inhibitory concentration ( IC50) > 10 μmol/L, and the difference in IC50 between drug-resistant and sensitive cell lines were analyzed using Mann-Whitney U test. The cancer driver mutation genes in drug-resistant cell lines were retrieved using the Cancer Cell Line Encyclopedia (CCLE) database (updated in December 2023). Using the protein-protein interaction (PPI) network functional enrichment analysis (STRING) database (updated in June 2024), PPI network analysis was performed on cancer driver mutation genes with biological functions. A confidence threshold of ≥ 0.7 (high confidence) and an average network node degree above 4 (high average) were selected to screen for cancer driver mutation genes with significant biological functions. Using the microRNA Data Integration Portal (mirDIP) database (updated in June 2024), the coexpression data of microRNA (miRNA) and mutant target genes were queried, miRNA-target gene pairs were screened according to the highest score threshold of 1% miRNA and interaction score > 0.9, and the regulatory effect of miRNA on mutant genes was analyzed. DNA methylation data were download from the Methylation in Human Cancer (MethHC) database (updated in June 2024) and the methylSig R software package was used to analyze the differentially methylated regions (DMR) of DNA methylation between drug-resistant and sensitive cell lines; genes with P < 0.05 and absolute difference > 0.2 were selected, and they were divided into high methylation gene group and low methylation gene group. Spearman correlation analysis and Spearman rank test were performed for the degree of methylation and gene expression, and the key genes with P < 0.01 were screened to reveal the relationship between methylation degree and gene expression. Results:As a result of searching the GDSC database, there were a total of 9 drug-resistant cell lines and 17 sensitive cell lines related to oxaliplatin treatment for ALL; after Z-score normalization of IC50 data between drug-resistant and sensitive cell lines, the average rank of drug-resistant cell lines was 21, and the average rank of sensitive cell lines was 8.5, with a statistically significant difference ( Z = -4.08, P < 0.01). Eight cancer driver mutation genes with significant biological functions that lead to drug resistance of the cell lines were screened using the CCLE database and STRING database. According to the mirDIP database, there were a total of 12 pairs of miRNA-target gene pairs with miRNA-target gene interaction scores >0.9. miRNA had strong regulatory effects on the expressions of NRAS and MAP2K1 target genes. In the MethHC database, the β values (numerical value of increased methylation level) of DMR for genes such as TP53, RXRG and SGIP in drug-resistant cell lines were 0.151, 0.165 and 0.149, respectively, compared to those in sensitive cell lines, the differences were statistically significant (all P < 0.01). The degree of methylation of SGIP gene was negatively correlated with the relative expression level of SGIP mRNA ( r = -0.71, P < 0.01), and SGIP gene underwent high methylation at promoter site 143886940. The cg08321569 locus in the TET2 gene domain of drug-resistant cell lines exhibited persistent high methylation, with a methylation level of β = 0.89. This locus was located 1.2 kb downstream of the transcription start point of exon 4, and the degree of TET2 methylation was negatively correlated with the relative expression level of TET2b mRNA ( r = -0.81, P < 0.01). Conclusions:TET2 methylation may be an important factor for oxaliplatin resistance in the treatment of ALL.

Objective:To explore the feasibility and safety of the combined liver and kidney procurement technique with preservation of the donor diaphragm.Methods:A retrospective study was conducted on the clinical data of 135 donors with pulmonary infection who underwent combined liver and kidney procurement and their corresponding 370 recipients in the Department of Transplantation, Guangxi Zhuang Autonomous Region People's Hospital from January 2021 to August 2023. According to whether the donor diaphragm was resected during procurement, the donors were divided into diaphragm preservation group (67 cases) and diaphragm resection group (68 cases). The t-test and chi-square test were used to compare the baseline characteristics of the donors, donor procurement time, surgical injury to organs, donor-derived infection (DDI), delayed graft function (DGF), primary non-function (PNF), and perioperative death between the two groups.Results:There were no statistically significant differences in age, sex, body mass index, number of organs procured, number of organs transplanted, number of organs discarded, or positive rate of sputum cultures for different strains between the two groups (all P>0.05). The donor procurement time was (46.70±12.61) min in the diaphragm preservation group and (45.79±12.78) min in the diaphragm resection group, with no statistically significant difference ( P=0.679). No surgical injuries to other abdominal organs (such as intestines or, in the diaphragm resection group, the lungs) occurred during procurement. After transplantation, the incidence of delayed graft function in kidney recipients was 7.32% (9/123) in the diaphragm preservation group and 11.67% (14/120) in the diaphragm resection group, with no statistically significant difference between the two groups ( P=0.279). The incidence of DDI was 0 in the diaphragm preservation group and 7.07% (13/184) in the diaphragm resection group, showing a statistically significant difference ( P<0.001). No cases of primary non-function or perioperative death occurred in either group. Conclusion:Compared with the conventional method, the combined liver and kidney procurement technique that preserves the donor diaphragm does not significantly increase operative time, organ injury, delayed graft function, primary non-function, or perioperative mortality. It significantly reduces the incidence of donor-derived infections and is worthy of clinical promotion and application.
