Objective: To explore the relationship between life skills, psychological resilience and subjective well-being among primary and secondary school students, so as to provide evidence for targeted adolescent mental health education. Methods: From September to November, 2025, a total of 5 831 primary and secondary school students from five cities (Beijing, Guangzhou, Shenzhen, Chongqing, Urumqi) were selected by convenience sampling. The Adolescent Subjective Well being Scale, School based Adolescents Life Skills Scale, and Adolescent Psychological Resilience Scale were used for investigation. Data were analyzed using t-tests, one way ANOVA, and linear regression. Results: The total mean score of students subjective well being was (5.46± 0.91) ; the total mean score of life skills was (3.69±0.64); the total mean score of psychological resilience was (3.66±0.69). Statistically significant differences in subjective well being scores were found among students grouped by gender, grade, school stage, residential city, living with parents or living with siblings ( t/F =4.14, 53.92, 14.53, 49.99, 13.49, 2.18, all P <0.01). Stratified regression analyses were performed by gender (adjusting for school stage, residential city and living arrangement) and by school stage (adjusting for gender, residential city and living arrangement), the regression results indicated that life skills of boys, girls, primary school students and junior high school students( β =0.54, 0.53, 0.50, 0.57) and their psychological resilience ( β = 0.56 , 0.60, 0.56, 0.60) were positively associated with subjective well being (all P <0.01). Conclusions Life skills and psychological resilience may be important protective factors for subjective well being among primary and secondary school students. School based mental health education should emphasize life skills training and resilience building to promote students subjective well being.

This study aims to investigate the characteristics of chitosan-loaded miR-146a nanoparti-cles and explore their protective effect against acute liver cell injury induced by LPS in vitro.Galac-tosylated arginine chitosan(GCA)nanoparticles were successfully synthesized,prepared and used to further prepare GCA-miR-146a nanoparticles with different mass ratios by ion cross-linking method.The binding efficiency of miR-146a by GCA nanoparticles was detected by gel retardation experiment.Particle size,morphology and potential were observed and detected by transmission e-lectron microscopy and Zetasizer NanoZS90 respectively.The cytotoxicity of GCA nanoparticles on HepG2 cells was detected by CCK-8 kit.Cellular uptake was assayed by fluorescence microscopy to select the optimum ratio for the further study.The LPS induced acute liver cell injury were evalua-ted by real-time fluorescence quantitative PCR.The results showed that the mass ratio of GCA-miR-146a was 5∶1.Encapsulation efficiency and drug loading efficiency of the nanoparticles reached 97.11％and 20.08％,respectively.The 100 nm nanoparticles with 1.15 mV surface charge showed uniform morphology.The GCA-miR-146a nanoparticles had no cytotoxicity and had high transfection efficiency on HepG2 cells.The study demonstrated that GCA-miR-146 ananoparticles could significantly increase the expression of miR-146a in HepG2 cells and reduce the mRNA ex-pression levels of IL-6 and TNF-α in vitro.The prepared GCA nanoparticles loaded with miR-146a had high loading efficiency and could protect LPS-induced acute liver cell injury in vitro.

BACKGROUND: Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA. METHODS: A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease. RESULTS: The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production. CONCLUSION Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

Objective:To evaluate artificial intelligence constructed by deep convolutional neural network (DCNN) for the site identification in upper gastrointestinal endoscopy.Methods:A total of 21 310 images of esophagogastroduodenoscopy from the Cancer Hospital of Chinese Academy of Medical Sciences from January 2019 to June 2021 were collected. A total of 19 191 images of them were used to construct site identification model, and the remaining 2 119 images were used for verification. The performance differences of two models constructed by DCCN in the identification of 30 sites of the upper digestive tract were compared. One model was the traditional ResNetV2 model constructed by Inception-ResNetV2 (ResNetV2), the other was a hybrid neural network RESENet model constructed by Inception-ResNetV2 and Squeeze-Excitation Networks (RESENet). The main indices were the accuracy, the sensitivity, the specificity, positive predictive value (PPV) and negative predictive value (NPV).Results:The accuracy, the sensitivity, the specificity, PPV and NPV of ResNetV2 model in the identification of 30 sites of the upper digestive tract were 94.62%-99.10%, 30.61%-100.00%, 96.07%-99.56%, 42.26%-86.44% and 97.13%-99.75%, respectively. The corresponding values of RESENet model were 98.08%-99.95%, 92.86%-100.00%, 98.51%-100.00%, 74.51%-100.00% and 98.85%-100.00%, respectively. The mean accuracy, mean sensitivity, mean specificity, mean PPV and mean NPV of ResNetV2 model were 97.60%, 75.58%, 98.75%, 63.44% and 98.76%, respectively. The corresponding values of RESENet model were 99.34% ( P<0.001), 99.57% ( P<0.001), 99.66% ( P<0.001), 90.20% ( P<0.001) and 99.66% ( P<0.001). Conclusion:Compared with the traditional ResNetV2 model, the artificial intelligence-assisted site identification model constructed by RESENNet, a hybrid neural network, shows significantly improved performance. This model can be used to monitor the integrity of the esophagogastroduodenoscopic procedures and is expected to become an important assistant for standardizing and improving quality of the procedures, as well as an significant tool for quality control of esophagogastroduodenoscopy.

A large number of data show that the prevalence rate of alcoholic liver injury （ALI） is increasing year by year， and it has become one of the main causes of death due to chronic liver diseases such as liver cancer and liver cirrhosis. Quitting drinking is the main method for the prevention of ALI in modern medicine， and the main treatment methods include Western medicine with antioxidant and anti－fibrotic effects and nutritional support. However， Western medicine tends to have an unsatisfactory treatment effect and can only alleviate initial symptoms， and severe ALI still requires surgical treatment. Studies have shown that the monomers extracted from natural drugs and foods have obvious preventive and therapeutic effects on ALI， with high safety and easy access. Therefore， this article systematically summarizes the main natural drug and food monomers used for the prevention and treatment of ALI and proposes the idea of the combination of drug and food for the prevention and treatment of ALI from the perspective of paying attention to the whole process of health， in order to explore more effective prevention， health care， and treatment methods and provide ideas for research on the prevention and control of ALI.

Objective:To explore the effect of narrative nursing on the psychological resilience, self-esteem, and medication compliance of adolescent depression patients.Methods:This study is a quasi-experimental study. From August 2021 to January 2022, 86 adolescent depression patients admitted to the Department of Mental Health at the First Hospital of Shanxi Medical University were selected as the subject by convenience sampling. According to the order of admission time, the patients were divided into a control group and an intervention group, with 43 patients in each group. The control group received routine nursing, while the intervention group received narrative nursing on the basis of routine nursing. We compared the scores of the Self-Rating Depression Scale (SDS), Hamilton Depression Scale (HAMD), Self-Esteem Scale (SES), Connor-Davidson Resilience Scale (CD-RISC), and Morisky Medication Adherence Scale (MMAS-8) before and after intervention between two groups of patients.Results:Before intervention, there was no statistically significant difference in SDS, HAMD, SES, CD-RISC, and MMAS-8 scores between the two groups ( P>0.05). After intervention, the total scores of SDS and HAMD in the intervention group were lower than those before intervention and in the control group, and the toughness, optimism, self-improvement scores and the CD-RISC total score, SES scores and MMAS-8 scores were higher than those before intervention and in the control group, with statistically significant differences ( P<0.05) . Conclusions:Narrative nursing can improve the depressive mood of adolescent depression patients, enhance their psychological resilience, self-esteem, and medication compliance, and can be promoted and applied in clinical practice.

Objective:Cushing′s disease(CD) is caused by the pituitary adrenocorticotroph hormone(ACTH) secreting adenomas, leading to increased serum cortisol levels and various abnormal metabolic processes. Untreated CD is linked to high mortality, thus it is critical to elucidate its pathogenesis. This study aims to explore the pathogenesis of pituitary ACTH adenomas using whole-genome sequencing analysis.Methods:Fresh tumor tissues and peripheral blood samples were collected in 9 confirmed cases of pituitary ACTH adenomas who underwent surgery. Whole genome sequencing was then performed, followed by analysis and verification of single nucleotide mutations, copy number variation(CNV) and chromosome structure variations.Results:Somatic USP8 mutations(p.Ser718del, p. Ser718Pro, p. Pro720Arg, p. Pro720Gln) were found in 5 patients, with a rate of 55.6%; CNV of USP8 was detected in 1 patient; TP53(p.Cys135Tyr), NF1(p.Val1049Glufs*11) and KMT2C(c.3323+ 1G>A) mutations were identified in 1 patient harboring wild-type USP8. CNV analysis showed a loss of heterozygosity in multiple chromosomes in a wild-type USP8 patient. Structural variations were found in 2 with unknown significance. No germline gene mutations were detected in this study.Conclusion:Somatic USP8 mutations, increased copy number of USP8, variations of tumor-related genes such as TP53 and extensive somatic CNV all contribute to pathogenesis of CD. Chromosomal structure variations may suggest high-risk pituitary ACTH adenomas, and call for frequent follow-up and aggressive treatment.

As the most commonly used antipyretic and analgesic drug,paracetamol(PA)coexists with neuro-transmitter dopamine(DA)in real biological samples.Their simultaneous determination is extremely important for human health,but they also interfere with each other.In order to improve the conductivity,adsorption affinity,sensitivity,and selectivity of TiO2-based electrochemical sensor,N-doped carbon@-TiO2 double-shelled hollow sphere(H-C/N@TiO2)is designed and synthesized by simple alcoholic and hydrothermal method,using polystyrene sphere(PS)as a template.Meanwhile,TiO2 hollow spheres(H-TiO2)or N-doped carbon hollow spheres(H-C/N)are also prepared by the same method.H-C/N@TiO2 has good conductivity,charge separation,and the highly enhanced and stable current responses for the detection of PA and DA.The detection limit and linear range are 50.0 nmol/L and 0.3-50 μmol/L for PA,40.0 nmol/L and 0.3-50 μmol/L for DA,respectively,which are better than those of carbon-based sen-sors.Moreover,this electrochemical sensor,with high selectivity,strong anti-interference,high reli-ability,and long time durability,can be used for the simultaneous detection of PA and DA in human blood serum and saliva.The high electrochemical performance of H-C/N@TiO2 is attributed to the multi-functional combination of different layers,because of good conductivity,absorption and electrons transfer ability from in-situ N-doped carbon and electrocatalytic activity from TiO2.

Objective To investigate the expression of ITGBL1 in hepatocellular carcinoma (HCC) and its role in promoting the proliferation, migration, and invasion of HCC cell lines. Methods RT-qPCR and immunohistochemistry were used in investigating ITGBL1 expression in 12 pairs of fresh HCC and adjacent normal liver tissue samples and 160 paraffin HCC specimens. The relationships of ITGBL1 expression level with clinicopathological parameters and prognosis were analyzed. HUH7 cell line with the stable overexpression of ITGBL1 and LM3 cell line with stable downregulated expression of ITGBL1 were constructed. The effects of ITGBL1 on the proliferation, migration, and invasion of HCC cells were examined by CCK8 assay, wound-healing assay, and Transwell invasion assay. Results The expression levels of ITGBL1 gene and protein in tumor tissues were higher than those in surrounding liver tissues. The high expression of ITGBL1 was correlated with serum AFP level, tumor capsular invasion, vascular invasion, tumor differentiation, and clinical stage (P < 0.05). The results of Kaplan-Meier analysis showed that patients with high expression of ITGBL1 had shorter DFS. In vitro, increased ITGBL1 expression promoted HCC cell proliferation, migration, and invasion, whereas ITGBL1 knockdown inhibited these processes. Conclusion ITGBL1 expression is highly expressed in HCC tissues, and ITGBL1 can increase the proliferation, migration, and invasion of HCC cells. However, the mechanism needs further study.
