Objective: To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students. Methods: From October to December 2022, a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity. Results: The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05). Conclusions The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

Objective:We summarize the clinical characteristics of surgeries in which the thyroid lobe is used as a transfer flap to treat early pharyngeal fistula following total laryngectomy.We also provide useful data for improving the diagnosis and management of this condition.Methods:Retrospective analysis was conducted on data from 8 patients with pharyngocutaneous fistulas after total laryngectomy for laryn-geal and pharyngeal cancer patients admitted to Hunan Provincial People's Hospital(The First Hospital Affiliated to Hunan Normal University)between October 2016 and October 2023.The surgeons performed a double-layer repair technique that included local inversion and a purse-string suture of the fistula using the thyroid lobe as a transfer flap.Clinical data were collected to analyze postoperative outcomes.Results:All eight patients experienced successful pharyngeal fistula repair.Postoperatively,these patients were managed with nasogastric tube feed-ing,liquid diet,and prophylactic antibiotics to prevent infection.After 10 days,their diet was changed to oral liquids,and their nasogastric tubes were removed.All patients were discharged after complete recovery.Conclusions:Use of the thyroid lobe as a transfer flap in a double-layer repair technique involving local inversion of the fistula is an effective method for repairing early pharyngeal fistula after total laryngectomy.This approach offers several advantages,including ease of flap harvesting,shortened operation time,reduced patient discom-fort,high transfer flap survival rate,and rapid postoperative recovery.The clinical efficacy of this technique is well-supported,making it a re-liable option for the management of early pharyngeal leaks.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

The objective of this study was to evaluate the protective effect and possible related mechanisms of Sophora subprostrate polysaccharide(SSP)on intestinal epithelial cell injury in-duced by Tert-Butyl hydroperoxide(TBHP).The optimal dose of TBHP and the safe concentra-tion range of SSP were determined using the MTT method.In this study,IPEC-J2 cells were divid-ed into five groups:the control group,the model group,the SSPL group,the SSPM group and the SSPH group,and the cell morphology,cell survival rate and LDH release rate were observed and measured.The content of intracellular reactive ROS was observed and determined by DCFH-DA staining.The content of MDA in the supernatant and the antioxidant index of cells were determined by the reagent kit.Transcriptome technology was employed to analyze the potential mechanisms by which SSP mitigates oxidative damage in IPEC-J2 cells.The results showed that treatment with 625 μmol/L TBHP for 2 h significantly reduced the activity of IPEC-J2 cells,markedly increased LDH release(P＜0.05),inhibited CAT superoxide SOD and glutathione GPX activities(P＜0.05),and significantly elevated MDA and ROS levels(P＜0.05).Compared to the model group,after SSP treatment,intracellular ROS levels were significantly reduced(P＜0.05),while CAT,SOD,and GPX activities were significantly increased(P＜0.05),and MDA content and LDH re-lease were significantly decreased(P＜0.05)in a dose-dependent manner.Transcriptome analysis revealed that TBHP treatment significantly altered the transcriptional profiles of IPEC-J2 cells,while SSP treatment could restore the transcriptional profiles of the damaged cells to a certain ex-tent.Gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)indicated that the differentially expressed genes between the CC and TBHP groups were significantly enriched in oxidative phosphorylation,ribosome,and other pathways.Meanwhile,the differentially expressed genes between the SSP and TBHP groups were mainly enriched in oxidative phosphorylation,ap-optosis,glyoxylate and dicarboxylate metabolism,and other pathways.These results suggest that TBHP may disrupt normal oxidative respiration in IPEC-J2 cells by affecting oxidative phospho-rylation and interfering with metabolism pathways involving glycine,serine,and threonine,leading to oxidative damage in intestinal epithelial cells.Conversely,SSP treatment may potentially restore oxidative phosphorylation processes,alleviate lysosomal damage,reduce cell apoptosis,and miti-gate oxidative damage in intestinal epithelial cells through modulation of oxidative phosphoryla-tion,apoptosis,and lysosomal pathways.This discovery provides a theoretical basis for the clinical application of SSP in alleviating oxidative damage in the porcine intestinal tract.

Objective To explore the changes in neural activity in patients with type 2 diabetes mellitus(T2DM)and their corre-lation with executive function,and to analyze the neural mechanisms underlying the decline in executive function in T2DM patients.Methods Thirty-one T2DM patients(T2DM group)and thirty-two healthy controls(HC)(HC group)matched for body mass index(BMI)underwent resting-state functional magnetic resonance imaging(rs-fMRI)scans and N-back task tests were included.Differ-ences in the amplitude of low-frequency fluctuation(ALFF),regional homogeneity(ReHo),and seed-based functional connectivity(FC)between the two groups were compared,and partial correlation analyses were performed between the difference results and N-back task performance.Results The T2DM group showed prolonged reaction time(RT)in the 1-back and 2-back tasks.T2DM patients exhibited increased ALFF in the bilateral caudate nucleus,left medial superior frontal gyrus,and right postcentral gyrus,as well as elevated ReHo in the right putamen.FC analysis revealed significant alterations in FC between the caudate nucleus,putamen,and multiple brain regions in T2DM patients,with some of these FC changes significantly correlated with RT and accuracy(ACC)in the N-back task.Conclusion The decline in executive function in T2DM patients may be associated with abnormal neural activity in brain regions such as the striatum,salience network,and frontoparietal control network.FC further decreases under increased cognitive load.These findings provide evidence for the study of the neural mechanisms of executive function impairment in T2DM patients.

Based on network pharmacology,molecular docking,and experimental validation,this study explored the mechanism by which Hypericum japonicum Thunb-Prunella vulgaris treat liver injury.Mice were randomly divided into four groups:a control group(CON),a model group(CCl4),a high-dose drug group(TXD-H),and a low-dose drug group(TXD-L).A mouse liver in-jury model was established using CCl4 induction.The pathological morphology of liver tissue was observed,and the serum levels of aspartate aminotransferase(AST)and alanine aminotransferase(ALT)were measured.Active ingredients of traditional Chinese medicine and targets related to these medicines and diseases were obtained from databases such as TCMSP,PubChem,Swiss Tar-get Prediction,GeneCards,and DisGeNET.The intersection of these targets was used to identify potential drug targets.A network diagram illustrating the relationships between"drug-active com-ponent-intersection target"was constructed using Cytoscape.Potential targets were analyzed using the STRING database for protein-protein interaction(PPI)analysis and the DAVID database for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis.Molecular docking validation was performed using AutoDock Tools software.Subsequently,key target genes,including those related to the NLRP3 inflammasome and pyroptosis,were detected to validate the molecular docking results.Animal experimental results showed that compared to the CON group,serum AST and ALT activities in the CCl4 group mice were significantly increased(P＜0.01),while in the TXD-L group,serum AST and ALT activities were significantly decreased(P＜0.05)compared to the CCl4 group,and in the TXD-H group,AST and ALT activities were significantly decreased(P＜0.01).Through network pharmacology,135 potential targets were i-dentified,with key components found to be tetramethoxyluteolin,quercetin,kaempferol,luteolin and morin based on degree values,and key targets including TNF,SRC,AKT1,EGFR and ESR1.GO enrichment analysis yielded 304 entries,while KEGG enrichment analysis identified 91 biologi-cal pathways.Molecular docking results demonstrated strong binding between the main compo-nents of Hypericum japonicurn Thunb-Prunella vulgaris and key targets.qPCR results showed that compared to the CON group,the CCl4 group exhibited upregulated relative expression levels of SRC,EGFR,TNF-α,AKT1,and IL-18 mRNA,with significant increases in MyD88,NF-κB,IL-1β,NLRP3,Caspase-1,and ASC mRNA(P＜0.05),and significant upregulation of TLR4 and GS-DMD mRNA(P＜0.01).Compared to the CCl4 group,the TXD-H group displayed significant downregulation of EGFR,AKT1,TLR4,IL-1β,and GSDMD mRNA(P＜0.01),significant decrea-ses in TNF-α,MyD88,NF-κB,NLRP3,and ASC mRNA(P＜0.05),while SRC,IL-18,and Caspase-1 mRNA showed a downward trend.In conclusion,Hypericum japonicum Thunb-Prunel-la vulgaris exerts hepatoprotective effects through multiple components and pathways,among which inhibition of the NF-κB-NLRP3 pathway to reduce hepatocyte pyroptosis may be one of the important pathways for its protective effects.

BACKGROUND:Traditional Chinese medicine has unique advantages in preventing and treating spleen-deficiency and hyperlipidemia.In basic studies,models of spleen-deficiency and hyperlipidemia are commonly found in rats,pigs,and other animals.This has limitations for medical research that can only use mouse models.It is urgent to establish and evaluate mouse models of spleen-deficiency and hyperlipidemia to support basic research on traditional Chinese medicine in preventing and treating spleen-deficiency and hyperlipidemia.OBJECTIVE:To establish a mouse model of spleen-deficiency hyperlipidemia.METHODS:Totally 24 C57BL/6J mice were randomly divided into normal group(n=12)and spleen-deficiency hyperlipemia group(n=12).Mice in normal group were fed basic diet.Mice in the spleen-deficiency hyperlipemia group were prepared with a diet disorder+fatigue internal injury+high-fat feeding method to establish a spleen-deficiency high-fat model.In the first 2 weeks,the mice were forced to swim to their endurance limit on a single day and were only fed cabbage,with free access to water.They were also gavaged with refined lard+high-fat feed on two-day intervals.After 2 weeks,the mice were fed a high-fat diet every day and the diet continued until 12 weeks.The mice were fed with a high-fat diet for 4 and 12 weeks,and their body weight,food intake,gripping strength,fecal water content,small intestinal charcoal propulsion rate,serum D-xylose and gastrin levels,spleen index and thymus index,blood lipid level,total body fat mass,body fat percentage,and liver lipid deposition were tested.RESULTS AND CONCLUSION:(1)Compared with the normal group,the body weight,fecal water content,total body fat mass,body fat percentage,triglyceride and total cholesterol levels of the mice in the spleen-deficiency hyperlipemia group fed with high-fat diet for 4 and 12 weeks were increased(P＜0.05);the daily food intake,gripping force,and D-xylose level of the mice fed with high-fat diet for 4 and 12 weeks were decreased(P＜0.05);the spleen index of the mice fed with high-fat diet for 4 weeks was increased(P＜0.05);the small intestinal carbon propulsion rate,gastrin level,spleen index,and thymus index of the mice fed with high-fat diet for 12 weeks were decreased(P＜0.05);the low-density lipoprotein cholesterol level of the mice fed with high-fat diet for 12 weeks was increased(P＜0.05).(2)The results of liver oil red O staining showed that the lipid deposition in the spleen-deficiency hyperlipemia group after 4 weeks of high-fat diet feeding was slightly more than that in the normal group,and the lipid deposition in the high-fat diet feeding for 12 weeks was significantly more than that in the normal group.(3)The results show that a stable spleen deficiency and hyperlipidemia mouse model can be prepared by the compound method of eating disorders,exhaustion,and high-fat feeding.
