Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

Objective: To develop a RHCE genotyping assay based on kompetitive allele-specific PCR (KASP) and assess its clinical accuracy for RhCE blood group determination. Methods: KASP primers were designed to interrogate three RHCE loci: the 109 bp insertion/deletion in intron 2, c. 307T>C, and c. 676C>G. A total of 1 194 RhD-positive inpatients from Chengdu were typed by both KASP genotyping and manual tube serology. Discordant samples (n=10) were retested by both methods and further resolved by Sanger sequencing. An additional 377 cases were tested for the c. 48C>G locus to evaluate the predictive accuracy of individual loci and combined locus testing for RhC antigen. Results: Genotyping concordance with serology was 100.0% for both the c. 676C>G locus (RhE/Rhe) and the c. 307T>C locus (Rhc). For RhC prediction using the 109 bp insertion, overall accuracy was 99.7% (1 191/1 194); the 3 discordant cases were confirmed by Sanger sequencing to be false negatives attributable to 109 bp deletion in intron 2. Testing the c. 48C>G allele for RhC prediction yielded 7 false positives, with an accuracy of 98.1% (370/377). RhC antigen status was determined by combining the 109 bp insertion and the c. 48C allele. After excluding 10 samples with inconsistent results between the two loci, the accuracy reached 100% in the remaining 367 samples. When both loci were applied in combination, accuracy reached 100% in the 367 cases with concordant results. Among the 1 194 patients, CCee (45.8%) and CcEe (31.7%) were the most common RhCE phenotypes. The e antigen had the highest positivity rate (92.2%), and the Ce haplotype was the most frequent (66.9%). Conclusion: The KASP-based RHCE genotyping method achieves high accuracy for clinical RhCE typing. Combining the 109 bp insertion/deletion with the c. 48C allele significantly improves RhC antigen prediction compared with either locus alone. This method was applied to RhCE genotyping of 1 194 RhD-positive inpatients in Chengdu, providing local RhCE phenotype and haplotype distribution data to support RhCE-matched transfusion practice.

Work serves as a critical means of obtaining resources, facilitating personal growth, realizing self-worth, and engaging in social interactions. However, work-related diseases pose significant threats to workers’ health and productivity, and impose considerable economic burdens. This article categorized work-related diseases into six major types, including musculoskeletal disorders, mental and behavioral disorders, cardiovascular and metabolic diseases, digestive system diseases, reproductive system diseases, and non-specific respiratory diseases, and summarized their risk factors, assessment methods, policy regulation, and prevention and control measures. Current research in this field predominantly relies on cross-sectional studies, which present limitations in causal inference and potential risks of bias. Future studies should expand sample sizes, optimize research designs, and establish multidimensional evaluation systems to comprehensively assess the health and economic impacts of work-related diseases. It is recommended to enhance the translation of research findings into practice, thereby providing a scientific basis for the occupational health protection system and promoting the well-being and sustainable development of the working population.

Background and aims Hepatocellular carcinoma (HCC) cells are metabolically reprogrammed for excessive uptake and metabolism of many nutrients. The tumor suppressive microRNA-148a-3p (miR-148a-3p) is downregulated in HCC, whereas its function in regulating HCC cell metabolism remains obscure. Herein we aimed to delineate the role of miR-148a-3p in HCC cell metabolism by using novel bioengineered miR-148a-3p (BioRNALeu/miR-148a-3p) agent produced in vivo. Methods BioRNALeu/miR-148a-3p was designed by using human leucyl transfer RNA fused hsa-pre-miR-34a carrier, overexpressed in Escherichia coli (E. coli), and purified to high homogeneity. After transfection into HCC cells, the released miR-148a-3p levels were assessed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Cell proliferation was determined by CellTiter-Glo assays. Targets were validated by dual-luciferase reporter assays, immunoblotting, and immunofluorescence confocal imaging. Glycolysis capacity was evaluated by Seahorse XF assays, and glucose, lactate, and amino acid levels were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. Results BioRNALeu/miR-148a-3p was efficiently processed into target miR-148a-3p in HCC cells to effectively inhibit cell proliferation in a dose- and time-dependent manner. Mechanistically, miR-148a-3p suppressed the protein levels of glucose transporter GLUT1/SLC2A1 and L-type amino acid transporter LAT1/SLC7A5 via acting on their 3′-untranslated regions, as well as amino acid transporter ASCT2/SLC1A5. These, in turn, led to a reduction of glucose uptake, lactate production, and glycolytic flux in HCC cells, and alteration of intracellular amino acid metabolome including glutamine, leucine, phenylalanine, tyrosine, and methionine. Conclusions Reintroduction of miR-148a-3p into HCC cells modulates glucose and amino acid metabolism via regulating multiple SLC transporters, thereby suppressing HCC cell viability. These findings highlight the role of miR-148a-3p in HCC cell metabolism and potential of bioengineered miRNA molecules for functional studies and therapeutic development.

A mounting body of research suggests that circRNAs significantly contribute to the develop-ment of myocardial fibrosis.The microarray results of human circular RNA expression profile indicated that circHERC4_041 expression increased in the myocardium of patients with heart failure,RT-qPCR a-nalysis confirmed that the myocardial expression level of circHERC4_041 in individuals with heart failure were considerably elevated compared to that in healthy organ donors.Fluorescence in situ hybridization(FISH)confirmed that circHERC4_041 was abundant in the cytoplasm of human cardiomyocyte AC16.Overexpression of circHERC4_041 in mouse myocardial fibroblasts(mCFs)mediated by adenovirus in-hibited the expression of fibrosis-related proteins in mCFs.Experiments involving cell proliferation,wound healing,and Transwell assays demonstrated that overexpression of circHERC4_041 suppressed the growth and mobility of mCFs(P＜0.001).Sequence analysis results suggested that circHERC4_041 con-tains potential ribosome entry sequence(IRES)and open reading frame(ORF).Western blot confirmed that circHERC4_041 could translate the 516 amino acid HERC4-516aa protein,which was mainly located in the cytoplasm of the cell.Cell functional experiments confirmed that circHERC4_041 inhibited the fi-brotic phenotype of mCFs by specifically translating HERC4-516aa(P＜0.05).The specific interaction between HERC4-516aa and transglutaminase 2(TGM2)was confirmed by IP-MS screening and Co-IP i-dentification.Further results found that the degradation of TGM2 was promoted through proteasome path-way.The overexpression of TGM2 in mCFs facilitated by adenoviral vectors could counteract the suppres-sive effects of HERC4-516aa on the fibrotic phenotype of mCFs.Therefore,this study confirmed that the HERC4-516aa protein translated by circHERC4_041 can specifically bind to TGM2 to inhibit the fibrotic phenotype of myocardial fibroblasts.

Glaucoma refers to a group of heterogeneous eye diseases, which is characterized by the gradual loss of visual field caused by the progressive deepening of the optic disc, optic nerve atrophy and slow apoptosis of retinal ganglion cells and their axons, ultimately leading to blindness.The vision loss caused by glaucoma is irreversible and it is a heavy burden on families and society.Therefore, the importance of early diagnosis and prevention should be emphasized.Genetic factors play an important role in the pathogenesis of glaucoma.In recent years, studies have found that long non-coding RNAs (lncRNAs) affect the occurrence and development of glaucoma by regulating the expression of glaucoma-related genes.For example, lncRNA ANRIL, lncRNA MALAT1, lncRNA GAS5 and lncRNA TUG1 can regulate the expression of related genes, and affect the survival of retinal ganglion cells by interfering with intraocular pressure, cell apoptosis, oxidative stress and other mechanisms.LncRNA ANRIL and LncRNA TGF-β2AS1 can regulate the expression of related genes in trabecular meshwork cells and affect the biological function of trabecular meshwork cells.LncRNA MEG3 and lncRNA FAM22B can regulate the expression of scar formation related genes and intervene in the process of filter passage scar formation after filtration.This article summarizes and comments on the characteristics of lncRNAs and the regulation mechanism of gene expression related to the occurrence and development of glaucoma, so as to provide new information for the prevention and treatment of glaucoma.

Objective Analyze the changes in serum levels of fibrinogen monomer(FM),high-density lipoprotein(HDL-C),homocysteine(Hcy),D-dimer(D-D)in patients with lower limb fractures before and after surgery,and analyze their correlation with deep vein thrombosis(DVT).Methods 187 patients with lower limb fractures admitted from July 2020 to June 2023 were divided into DVT group(53 cases)and non DVT group(134 cases)according to the presence or absence of DVT after surgery.Independent sample t-tests were used to compare the levels of serum FM,HDL-C,Hcy,and D-D between the two groups on the day before and after surgery.Spearman correlation analysis was used to investigate the correlation between serum FM,HDL-C,Hcy,D-D and DVT on the day before and after surgery.Receiver operating characteristic(ROC)curves were used to analyze the effects of serum FM,HDL-C,Hcy,and D-D on lower limbs on the day after surgery.The predictive value of postoperative DVT in fracture patients.Results Compared with 1 day before surgery,the serum FM,HDL-C,Hcy,and D-D levels in both groups increased on the day after surgery(P＜0.05),and compared with the non DVT group,the DVT group had higher serum FM,HDL-C,Hcy,and D-D levels on the day after surgery(P＜0.05).According to Spearman correlation analysis,there was no correlation between preoperative serum FM,HDL-C,Hcy,D-D and DVT on day 1(P＞0.05),while postoperative serum FM,HDL-C,Hcy,D-D were positively correlated with DVT on day 1(P＜0.05).ROC curve analysis showed that the AUC of FM,HDL-C,Hcy,D-D,and their combined prediction of postoperative DVT in patients with lower limb fractures on the 1st day after surgery were 0.781,0.756,0.754,0.781,and 0.879,respectively.The sensitivity and specificity corresponding to the optimal critical value were:After 1 day of surgery,the FM was 45.3％and 100.0％,the HDL-C was 100.0％and 49.3％,the Hcy was 49.1％/100.0％,and the D-D was 100.0％and 49.3％,respectively.The combined rates of the four were 83.0％and 86.6％.Conclusion Compared with patients with lower limb fractures who did not experience DVT after surgery,patients with lower limb fractures experienced elevated serum levels of FM,HDL-C,Hcy,and D-D.There was a correlation between preoperative and postoperative serum levels of FM,HDL-C,Hcy,and D-D.The combination of serum levels of FM,HDL-C,Hcy,and D-D at 1 day after surgery has a high predictive value for postoperative DVT in patients with lower limb fractures.

Central venous access device-related thrombosis (CRT) refers to the obstructive or non-obstructive clots formed around the central venous access device (CVAD).It may lead to risks such as loss of vascular access, pulmonary embolism, post-thrombotic syndrome.Due to the heterogeneity of underlying diseases and the specific characteristics of CVAD placement in children, there is insufficient evidence for the diagnosis and treatment of CRT in children.This article reviews the diagnosis, treatment and prevention of CRT in children to provide reference for clinical management.

Objective To analyze the spatiotemporal evolution patterns of mortality and disease burden of smoking-related prostate cancer(PCa)from 1990 to 2021 and to predict the future trends,so as to provide evidence-based insights for optimizing regional PCa prevention policies and smoking cessation interventions.Methods Based on data from the Global Burden of Disease Study(GBD)2021,annual mortality,disability-adjusted life years(DALYs),years of life lost(YLLs),years lived with disability(YLDs),and age-standardized rates(ASRs)for PCa across 204 countries and 21 regions from 1990 to 2021 were obtained.Estimated annual percentage change(EAPC)was used to assess the disease burden and mortality of smoking-related PCa across global,regional,socio-demographic index(SDI),and age groups.An autoregressive integrated moving average(ARIMA)model was employed to predict trends in these indicators up to 2050.Results In 2021,smoking-related PCa caused 12 992 global deaths,a 30.74％increase compared to 1990.However,from 1990 to 2021,the global age-standardized mortality rate(ASMR),age-standardized DALYs rate(ASDR),age-standardized YLDs rate(ASYR),and age-standardized YLLs rate(ASLR)for smoking-related PCa declined,with EAPCs being-1.43(95％CI:-1.77--1.12),-1.39(95％CI:-1.66--1.12),-0.41(95％CI:-0.67--0.15)and-1.51(95％CI:-1.78--1.23).In 2021,the region with the highest number of deaths from PCa was Asia(4663 deaths),followed by Europe(4647 deaths),and Oceania had the lowest number of deaths(9 deaths).From 1990 to 2021,the mortality rate of PCa in most regions generally showed a downward trend.High SDI regions showed the most significant declines in ASMR,ASDR,and ASLR[EAPCs:-3.17(95％CI:-3.31--3.02),-2.91(95％CI:-3.02--2.83),and-3.22(95％CI:-3.35--3.09)].For ASYR,only high-SDI regions exhibited a decline,whereas low-middle-SDI regions saw the largest increase[EAPC:1.26(95％CI:1.19-1.33)].In 2021,the number of PCa deaths was more concentrated in the age groups of 70-74 and 75-79,with 2312 and 2278 deaths,respectively.From 1990 to 2021,ASMR,ASDR,and ASLR showed an overall downward trend,EAPC were-2.84(95％CI:-3.21--1.83),-2.77(95％CI:-3.13--1.75),and-2.84(95％CI:-3.14--1.71),with the most significant decline observed in individuals aged 35-39.Projections to 2050 indicated continuing declines in all burden metrics,which would stabilize in later years.Conclusion Despite a global decline in smoking-related PCa burden over the past three decades,significant regional disparities persist,with low-and middle-income countries facing ongoing challenges.Implementing stricter tobacco control policies is critical to mitigating smoking-related health risks.

Tuberculosis is a highly infectious disease that poses a significant threat to public health, particularly in resource-limited regions where its incidence remains high. In 2022, the World Health Organization (WHO) released the WHO Consolidated Guidelines on Tuberculosis. Module 4: Treatment- Tuberculosis Care and Support, aimed at improving the quality of care and treatment for tuberculosis patients. This guideline outlines the multifaceted challenges faced by tuberculosis patients during treatment and offers evidence-based intervention strategies. It highlights key areas such as psychological support, nutritional management, and social care. This paper provides an interpretation of the main contents of the guideline to offer evidence-based practice guidance for healthcare providers, and to support clinical staff in delivering targeted patient care interventions.
