Objective: To investigate the prevalence and associated factors of depressive symptoms among junior and senior high school students in Beijing from 2019 to 2023, in order to provide a scientific basis for interventions targeting high risk groups. Methods: From 2019 to 2023, a stratified cluster random sampling method was used to select 88 927 junior and senior high school students from 16 districts in Beijing. The Center for Epidemiologic Studies Depression Scale(CES-D) was conducted to assess depressive symptoms. The Chi square test was used to compare the detection rates of depressive symptoms among different student groups, and the trend Chi square test was employed for trend analysis of detection rates across the years. Multivariate Logistic regression analysis was applied to examine the association between the detection of depressive symptoms and related factors among junior and senior high school students. Results: From 2019 to 2023, the prevalence rates of depressive symptoms among junior and senior high school students in Beijing were 20.45%, 18.19%, 16.64%, 17.89% and 18.17%, respectively, with an overall downward trend ( χ 2 trend =27.51, P <0.01). Multivariate Logistic regression analysis revealed that after adjusting for gender, monitoring year, educational stage,family structure,boarding status and has taken a medical leave of absence in the past year unhealthy dietary behaviors ( OR=1.80, 95%CI =1.73-1.87), physical inactivity ( OR=1.24, 95%CI =1.19-1.29), try smoking ( OR=1.46, 95%CI =1.35-1.58), try alcohol( OR=1.96, 95%CI =1.88-2.05), Internet addiction ( OR=3.88, 95%CI =3.57-4.22), and adverse ear related behavior ( OR=1.82, 95%CI =1.71-1.93) were all associated with an increased risk of depressive symptoms among junior and senior high school students (all P <0.05). Conclusions The prevalence depression symptoms among middle school students in Beijing showed a fluctuating downward trend from 2019 to 2023. Targeted interventions should be adopted to reduce the occurrence of depression symptoms among junior and senior high school students.

Objective: To investigate the current status of screening myopia and anxiety symptoms and associated factors among junior and senior high school students in Beijing, so as to provide evidence for myopia prevention and control and the improvement of mental health among adolescents. Methods: From September to November 2024, a total of 17 245 junior high schools, general senior high schools and vocational high schools from 16 districts in Beijing were enrolled by stratified cluster sampling method. Questionnaire surveys and vision screening were conducted to collect data on anxiety symptom and screening diagnosed myopia. The Chi square test was used to analyze the co-occurrence of myopia and anxiety symptoms, and binary Logistic regression analysis was adopted to explore the related factors of the co-occurrence. Results: The overall detection rate of cooccurrence screening myopia and anxiety symptoms among Beijing junior and senior high school students was 6.00%. The detection rate was higher in females ( 7.15 %) than in males (4.90%), higher in urban areas (6.65%) than in suburban areas (5.41%), and higher in general senior high school students (7.61%) than in vocational high school students (6.46%) and junior high school students (4.65%). All differences were statistically significant ( χ 2=38.49, 11.66, 54.88, all P <0.01). Binary Logistic regression analysis showed that female gender ( OR =1.43), general senior high school ( OR =1.60), vocational high school ( OR =1.59), daily sugar sweetened beverage intake ( OR =1.66), participation in academic extracurricular classes in preschool ( OR =1.30), electronic screen use for more than 2 hours per day ( OR =1.21), and insufficient sleep ( OR =2.41) were associated with an increased risk of co-occurring screening diagnosed myopia and anxiety symptoms (all P <0.05). Conclusions The co-occurrence of screening diagnosed of myopia and anxiety symptoms among junior and senior high school students in Beijing is common. Female gender, senior high school students, and unhealthy lifestyle behaviors are all risk factors for the co-occurrence of myopia and anxiety symptom. Comprehensive intervention measures can be adopted to simultaneously promote vision protection and mental health among junior and senior high school students.

Objective:To explore the clinical features and genetic characteristics of three patients with Infantile liver failure syndrome type 2 (ILFS2).Methods:Three children who were diagnosed with ILFS2 at the Children′s Hospital Affiliated to Zhengzhou University from February 2023 to February 2024 were selected as the study subjects. Clinical data of the children were collected. Peripheral blood samples of the children and their parents were collected and subjected to whole exome sequencing (WES). Candidate variants of the NBAS gene were verified by Sanger sequencing. This study was approved by the Ethics Committee of the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2024-k-069). Results:The three children had presented with fever-triggered recurrent acute liver failure. All of them were found to harbor compound heterozygous variants of the NBAS gene, including c. 3596G>A and c.1181A>T in child 1, c.2617C>T and c. 2T>C in child 2, and c. 3596G>A and c. 2817_2818insT in child 3. Among these, the c. 1181A>T and c. 2817_2818insT variants were unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), they were respectively classified as variants of uncertain significance (PM2_Supporting+ PM3+ PP3) and pathogenic (PVS1+ PM2_Supporting+ PM3). Conclusion:Combined with the patient′s clinical phenotype, the compound heterozygous variants of the NBAS gene probably underlay the pathogenesis of ILFS2 in the three children. For children with fever-related acute liver failure of unknown causes, the possibility of this disease should be suspected, and genetic testing may facilitate the diagnosis. Early diagnosis and timely intervention can significantly improve the prognosis. Discoveries of the c. 1181A>T and c. 2817_2818insT variants have enriched the mutational spectrum of the NBAS gene.

Objective:To explore the clinical and genetic characteristics of a boy with X-linked familial Behcet-like autoinflammatory syndrome-2 (AIFBL2).Methods:A boy who was admitted to Children′s Hospital Affiliated to Zhengzhou University in December 2023 due to recurrent oral ulcers for 2 years, intermittent abdominal pain and fever for more than 1 year was selected as the study subject. Clinical data of the patient was collected. Whole exome sequencing (WES) was carried out, and candidate variant was verified by Sanger sequencing and bioinformatic analysis. A literature search was conducted in OMIM, PubMed, Wanfang Data Knowledge Service Platform, China Biomedical Literature Service System, and the VIP database using the keywords " ELF4 gene" " deficiency in ELF4, X-linked" " ELF4 deficiency" and " DEX" to identify recently published studies. This study was approved by the Medical Ethics Committee of the Children′s Hospital Affiliated to Zhengzhou University (Ethics No.: 2023-H-K44). Results:The patient, a 12-year-old male, presented with recurrent mouth ulcers, fever and abdominal pain. Lymphocyte subsets showed a significant decrease in NK cells. Abdominal CT showed thickening of local intestinal wall in the lower right abdomen. Colonoscopy revealed a solitary deep longitudinal ulcer in the ileocecal region. Genetic testing revealed a hemizygote missense variant c. 687C>G, with his mother showing the same mutation at this locus. According to the guidelines of the American College of Medical Genetics and Genomics (ACMG), the variant was considered likely pathogenic (PP1+ PP2+ PM2_Supporting+ PP3+ PP4). Literature review has found 19 AIFBL2 patients including 1 patient from this study. Mouth ulcer, fever, rash and abdominal pain were the primary clinical manifestations, for which genetic testing is the main diagnostic method.Conclusion:The hemizygote c. 687C>G missense variant of the ELF4 gene probably underlay the AIFBL2 in this child, which has provided a basis for his clinical diagnosis and genetic counseling.

Objective:To investigate the mechanism through which ginsenoside Re enhances lipid metabolism and mitochondrial function in H9C2 cardiomyocytes induced by high glucose and high fat, specifically by modulating AMP-activated protein kinase(AMPK)and specificity protein 1(Sp1).Methods:The H9C2 cardiomyocyte model was cultured in a high-glucose and high-lipid(HGHL)environment.Six groups were established: a control group(CON group), a model group(HGHL group), a ginsenoside Re 60 μmol/L group(Re 60 μmol/L), a model+ ginsenoside Re 20 μmol/L group(HGHL+ Re 20 μmol/L), a model+ ginsenoside Re 40 μmol/L group(HGHL+ Re 40 μmol/L), and a model+ ginsenoside Re 60 μmol/L group(HGHL+ Re 60 μmol/L).Cell morphology was assessed using hematoxylin and eosin(HE)staining, while intracellular oil and triglyceride content were evaluated using oil red O staining.Reactive oxygen species(ROS)levels were measured with a fluorescence kit, apoptosis was assessed using TUNEL staining, and the expressions of phosphorylated AMPK, Sp1, nuclear respiratory factor 1(Nrf1), and peroxisome proliferator-activated receptor gamma coactivator 1 alpha(PGC1α)were analyzed via Western blotting.Results:Compared to the control group, the model group exhibited significant increases in cell hypertrophy, ROS levels, apoptosis, and intracellular TG.Conversely, the expressions of pAMPK, Nrf1, and PGC1α were significantly decreased, while the expression of Sp1 was significantly increased( P<0.05).Compared to the model group, treatment with Ginsenoside Re at concentrations of 20 μmol/L, 40 μmol/L, and 60 μmol/L significantly improved cell hypertrophy, reduced ROS levels, alleviated apoptosis, and decreased intracellular TG levels.Additionally, the expressions of pAMPK, Nrf1, and PGC1α were significantly increased, while Sp1 expression was significantly decreased in a dose-dependent manner( P<0.05). Conclusions:Ginsenoside Re enhances lipid metabolism, mitigates mitochondrial oxidative stress, and reduces apoptosis in H9C2 cardiomyocytes induced by high glucose and high lipid conditions.This effect is associated with the regulation of AMPK and Sp1 proteins, leading to increased expressions of pAMPK, Nrf1, and PGC-1α, and decreased expression of Sp1.

This article reports the diagnosis and treatment of a patient with diffuse large B-cell lymphoma (DLBCL) initially manifested as acquired von Willebrand syndrome (AvWS), along with a literature review. The patient, a 22-year-old male, was diagnosed with hereditary von Willebrand disease at the initial stage due to repeated mucosal bleeding, and was later diagnosed with DLBCL (non germinal center type, Ann Arbor stage Ⅳ) due to chest wall mass. Through chemotherapy combined with autologous hematopoietic stem cell transplantation and zebutinib maintenance therapy, the patient achieved sustained complete remission, and the coagulation function returned to normal. This case provides an important reference for the diagnosis and treatment of lymphoma associated AvWS, and highlights the importance of early recognition of basic diseases.

Objective: To explore the association between CDKAL1 rs35261542, FAIM2 rs 3205718, and VGLL4 rs 2574704 polymorphisms with childhood obesity and related metabolic phenotypes to provide evidence for personalized prevention and management strategies. Methods: Based on the 2023 Long term Nutritional Health Effects of Early Childhood Nutrition Package Intervention project, the study enrolled 1 078 children aged 5-7 years from four counties in Henan (Songxian and Ruyang countries) and Guizhou (Guiding and Fuquan countries) provinces. Using BMI Z scores, 87 overweight and obese(OVOB) children were selected and matched by sex, age, and BMI Z score with 117 normal weight controls. Participants were further stratified into four metabolic phenotype groups: metabolically healthy normal weight (MHNW, n =51), metabolically unhealthy normal weight (MUNW, n =66), metabolically healthy obesity (MHO, n =31) and metabolically unhealthy obesity (MUO, n =56) based on four conventional cardiometabolic risk factor (CR) criteria. Data were collected through questionnaires, anthropometric measurements, serum biochemical tests, and KASP genotyping. The distribution of three genetic polymorphisms ( CDKAL1 rs35261542, FAIM2 rs3205718, VGLL4 rs 2574704) across metabolic subgroups was analyzed. Multivariate Logistic regression models assessed associations between these polymorphisms and obesity/metabolic phenotypes. Results: Multivariate Logistic regression analysis showed that Homozygous mutant AA genotype of CDKAL1 rs 35261542 was positively associated with OVOB( OR =3.63), MHO ( OR =11.04), MUO ( OR = 4.88 ) ( P <0.05). Homozygous TT genotype of FAIM2 rs 3205718 increased OVOB risk ( OR =4.44, P <0.05) but showed no association with metabolic phenotypes ( P >0.05). Homozygous mutant TT of VGLL4 rs 2574704 reduced the risks of MHO and MUO ( OR = 0.30, 0.24， P <0.05). Cumulative genetic effects analysis demonstrated carriers of 1 or 2 risk genotypes of rs 35261542 and rs 3205718 had progressively higher OVOB risk ( OR =2.53, 20.79), and the combination of rs 35261542 and rs 2574704 increased risks for both MHO ( OR =8.50) and MUO ( OR =5.00) ( P <0.05). Conclusions The AA genotype of rs 35261542 ( CDKAL1 ) positively correlates with childhood obesity and metabolic abnormalities. The TT genotype of rs 3205718 ( FAIM 2) increases obesity risk but not metabolic phenotypes. The TT genotype of rs 2574704 ( VGLL 4) shows protective effects against metabolic dysfunction. Risk genotypes exhibit dosedependent cumulative effects on obesity and metabolic outcomes.

OBJECTIVE: To explore the clinical features of the sepsis in immunocompromised hosts and establish an early warning equation. METHODS: A retrospective study was conducted on sepsis patients admitted to the intensive care unit (ICU) of Binzhou Medical University Hospital from October 2011 to October 2022. General information, infection site, etiology results and drug susceptibility, clinical symptoms, inflammatory indicators, acute physiology and chronic health status evaluation II (APACHE II), sequential organ failure assessment (SOFA), incidence of immune paralysis, and outcome during hospitalization were collected. Based on whether they met the diagnostic criteria for immunocompromised hosts, patients were divided into immunocompromised group and immune normal group. The clinical information of the two groups were compared. Multivariate Logistic regression was used to analyze the risk factors of patients with immunocompromised sepsis and the regression equation model was initially established. Omnibus test and Hosmer-Lemeshow test were used to evaluate the model. RESULTS: A total of 169 patients with sepsis were included, including 61 in the immunocompromised group and 108 in the normal immune group. The top 3 infection sites in the immunocompromised group were bloodstream infection, pulmonary infection and abdominal infection. The top 3 infection sites in the normal immune group were pulmonary infection, bloodstream infection and abdominal infection. The infection rate of Gram-negative bacteria in the immunocompromised group was significantly lower than that in the normal group [49.2% (30/61) vs. 64.8% (70/108), P < 0.05]. The infection rate of Gram-positive bacteria [27.9% (17/61) vs. 13.9% (15/108)] and multidrug-resistant bacteria [54.1% (33/61) vs. 29.6% (32/108)] were significantly higher than those in normal immune group (both P < 0.05). In terms of clinical symptoms, the proportion of fever in the immunocompromised group was significantly lower than that in the immune normal group [49.2% (30/61) vs. 66.7% (72/108), P < 0.05]. Neutrophil count (NEU) and neutrophil percentage (NEU%) in the immunocompromised group were significantly lower than those in the normal immune group. Lymphocyte percentage (LYM%), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), APACHE II score, combined shock rate, incidence of immune paralysis, and mortality during hospitalization in the immunocompromised group were significantly higher than those in the normal immune group. Logistic regression analysis showed that NLR, CRP and PCT were risk factors for patients with immunocompromised sepsis (all P < 0.05). The above indicators were used as covariables to construct a Logistic regression equation, that was, Logit (P) = 0.025X₁+0.010X₂+0.013X₃-2.945, where X₁, X₂ and X₃ represent NLR, CRP and PCT respectively. Omnibus test and Hosmer-Lemeshow test show that the model fits well and has certain early warning value. CONCLUSIONS Patients with immunocompromised sepsis have more intense inflammatory response, with Gram-negative bacteria being the predominant pathogen, and a higher incidence of Gram-positive bacterial infections and multi-drug resistant infections. The severity of the disease, in-hospital mortality, the incidence of shock and the incidence of immune paralysis after sepsis were significantly higher. NLR, CRP and PCT were independent risk factors for sepsis in immunocompromised hosts. The regression equation constructed based on this may have early warning significance for patients with immunocompromised sepsis.
