Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease. The pathogenesis of AIH remains unclear, but it is mainly autoimmune injury caused by the breakdown of autoimmune tolerance due to the abnormal activation of the immune system, while the specific molecular mechanism remains unknown. Recent studies have shown that abnormal amino acid metabolism plays an important role in the development and progression of AIH. This article reviews the research advances in amino acid metabolic reprogramming in AIH, in order to provide a theoretical basis for amino acid metabolism as a new target for the clinical diagnosis and treatment of AIH.

Objective:
To assess the awareness and associated factors of wild mushroom poisoning among students in Guizhou Province, so as to provide a scientific foundation for wild mushroom poisoning prevention and control among students.
Methods:
By a multi stage stratified cluster random sampling method, 1 162 students from Guizhou Province were selected in May 2024. The questionnaire survey was administered to evaluate knowledge regarding wild mushroom poisoning. Data were analyzed employing the χ 2 test and Logistic regression model.
Results:
Among the nine questions assessing awareness of wild mushroom poisoning, only three had the awareness rate exceeding 70%. Binary Logistic regression analysis revealed that students who "actively learn about the prevention of wild mushroom poisoning" ( OR=0.48, 95%CI =0.26-0.92) and "spread knowledge about wild mushroom poisoning to others" ( OR=0.47, 95%CI =0.33-0.69) scored higher on the wild mushroom poisoning knowledge questions ( P <0.05). Conversely, students with a habit of consuming wild mushrooms ( OR=1.52, 95%CI =1.15-2.02) scored lower ( P < 0.05 ). 42.3% of the students suggested that scientific dissemination and publicity about wild mushrooms should be intensified.
Conclusions
The awareness rate of wild mushroom poisoning knowledge among students in Guizhou Province requires further attention. Comprehensive knowledge should be disseminated systematically through various channels to further improve students awareness of the prevention and control of wild mushroom poisoning.
3.Elevated blood pressure and its association with dietary patterns among Chinese children and adolescents aged 7-17 years
Chinese Journal of School Health 2025;46(6):863-867
Objective:
To understand the prevalence of elevated blood pressure and its association with dietary patterns in children and adolescents in China, providing evidence for developing dietary intervention of hypertension in children and adolescents.
Methods:
Data were derived from the China Children s Nutrition and Health System Survey and Application Project(2019-2021). A stratified cluster random sampling method was used to include 7 933 participants from 28 survey sites in seven major regions of Northeast, North, Northwest, East, Central, South and Southwest China. Multivariate Logistic regression models were used to analyze associations between demographic characteristics, nutritional status and elevated blood pressure. Exploratory factor analysis identified dietary patterns, which were divided into three quartile groups (T3, T2, T1) based on factor scores (compliance for dietary pattern) from high to low, and multivariate Logistic regression model assessed the correlation between elevated blood pressure and dietary patterns.
Results:
The prevalence of elevated blood pressure was 15.4% among Chinese children aged 7-17 years. Significant differences were observed across nutritional status (reference: underweight; normal weight: OR =1.57; overweight: OR = 2.61 ; obesity: OR =3.85), urban/rural residence (reference: rural; urban: OR =0.86), and paternal education (reference: junior high school and below; bachelor degree or above: OR =0.68) ( P <0.05). The detection rates of high blood pressure in T3 group children and adolescents with four dietary patterns (staple food, animal based food, snacks, vegetables and fruits) were 15.7%, 14.6%, 16.8%, and 15.8%, respectively. After adjusting for residence, paternal education, and nutritional status, the "snack dietary pattern" (mainly candy, sugar sweetened beverages, and processed snacks) showed positive associations with elevated blood pressure in T2 ( OR =1.21) and T3 ( OR =1.19) tertiles ( P <0.05).
Conclusions
The snack dietary pattern is a related factor for elevated blood pressure in children and adolescents. Restricting unhealthy snack intake may promote cardiovascular health.

Objective To investigate the effects and underlying mechanisms of a spray prepared from exosomes derived from M2 macrophages induced by interleukin-4 (IL-4) and tantalum particles (Ta) on the healing of pressure ulcers. Methods Bone marrow-derived macrophages were polarized into M2 macrophages using IL-4 or Ta, and exosomes (Exo-IL-4/Exo-Ta) were extracted. The regulatory effects of Exo-IL-4/Exo-Ta on M1 macrophage phenotypes and fibroblast matrix secretion were evaluated in vitro. Proteomic analysis was conducted to explore the biological processes and regulatory networks associated with Exo-Ta. A rat pressure ulcer model was used to assess the effects of Exo-IL-4/Exo-Ta spray on wound healing rate, inflammatory cell infiltration, and collagen deposition. Results In vitro, Exo-IL-4/Exo-Ta induced the polarization of M1 macrophages to M2 macrophages, reduced the secretion of pro-inflammatory factors, and promoted the expression of anti-inflammatory substances. Additionally, Exo-IL-4/Exo-Ta enhanced the production of collagen and fibronectin in fibroblasts. Proteomic analysis revealed that Exo-Ta primarily participated in biological processes such as energy metabolism and macromolecule biosynthesis. In vivo, Exo-IL-4/Exo-Ta spray accelerated wound healing, reduced inflammatory infiltration, and improved tissue remodeling in the rat pressure ulcer model. Conclusion Exosome sprays derived from M2 macrophages could accelerate pressure ulcer healing by modulating inflammation and promoting tissue regeneration, which demonstrated excellent clinical application potential.

Objective To explore the influences of long-chain noncoding RNA DHRS4-AS1 (lncRNA DHRS4-AS1) on the proliferation, invasion, migration, and apoptosis of thyroid cancer (TC) cells by regulating the microRNA-221-3p (miR-221-3p)/suppressor of cytokine signaling 3 (SOCS3) signaling axis. Methods Quantitative real-time PCR (qRT-PCR) was applied to detect the expression of lncRNA DHRS4-AS1, miR-221-3p, and SOCS3 mRNA in TC cell lines, and the optimal cell line was selected for subsequent experiments. FTC-133 cells were divided into five groups: control group, pcDNA-NC group, DHRS4-AS1 group, DHRS4-AS1 combined with agomir NC group, and DHRS4-AS1 combined with miR-221-3p-agomir group. Transfection efficiency was assessed using qRT-PCR. Dual luciferase reporter assays were applied to verify the targeting interaction between lncRNA DHRS4-AS1, SOCS3, and miR-221-3p. Western blot analysis was used to detect the expression of SOCS3 in FTC-133 cells. EdU method was used to measure cell proliferation. Flow cytometry was applied to measure the apoptosis of FTC-133 cells. Scratch experiment was applied to measure the migration of FTC-133 cells. Transwell chamber was applied to detect the invasion of FTC-133 cells. Nude mouse transplantation tumor experiment was used to observe the effect of lncRNA DHRS4-AS1 on the growth of TC transplantation tumors. Results Dual luciferase reporter assays showed a targeting relationship between lncRNA DHRS4-AS1, miR-221-3p, and SOCS3. LncRNA DHRS4-AS1 and SOCS3 were downregulated and miR-221-3p was upregulated in FTC-133 cells. Overexpression of lncRNA DHRS4-AS1 inhibited proliferation, migration, and invasion of FTC-133 cells, while inducing apoptosis. Conversely, miR-221-3p overexpression reversed these inhibitory effects, and suppressed the apoptosis. Nude mouse transplantation experiment observed that overexpression of lncRNA DHRS4-AS1 resulted in a decrease in tumor tissue quality and volume, and a decrease in miR-221-3p expression and an increase in SOCS3 expression. Conclusion LncRNA DHRS4-AS1 is downregulated in FTC-133 cells. Overexpression of lncRNA DHRS4-AS1 can inhibit the proliferation, invasion, and migration of TC cells and induce apoptosis by regulating the miR-221-3p/SOCS3 signaling axis.

Under the backdrop of the "Healthy China 2030" strategy, running has become the most common form of exercise. Fitness running is a kind of endurance aerobic exercise. Compared with swimming, aerobics, and other sports with high activity and intensity, the risk of lower limb fatigue injury during fitness running is higher. In this review paper, the risk factors for running-related injuries were summarized by consulting and analyzing the database and focuses on discussing and analyzing the impact of running on joints. The results showed that hip adduction, knee bending, and ankle joint abnormalities are the three joint-related factors that cause the main injuries during running. Four rehabilitation intervention methods for running-related injuries were proposed, that can guide patients to generate personalized rehabilitation treatment plans through training.
