Objective: To explore the correlation between parent-child separation experience and non suicidal self injury (NSSI) behavior among junior and senior high school students, so as to provide a reference for the prevention and improvement of NSSI behavior among junior and senior high school students. Methods: Using a stratified cluster random sampling method, 3 114 junior and senior high school students aged 11-19 years were recruited from Chenzhou and Jishou cities in Hunan Province between November 2024 and September 2025. A self designed questionnaire and the Functional Self injury Behavior Assessment Scale were used to collect information on parental labor migration and adolescents NSSI behavior status. Binary Logistic regression model was used to analyse the association between parent-child separation experiences and NSSI behavior among junior and senior high school students, with further stratified analysis by gender. Results: The prevalence rate of NSSI behavior among junior and senior high school students was 9.9%, and the overall incidence of parent-child separation was 48.9%, comprising 17.1% separated from their father only, 5.5% separated from their mother only, and 26.3% separated from both parents. After adjusting for variables such as age, gender, and ethnicity, the results of binary Logistic regression analyses indicated that adolescents with parent-child separation experiences had a higher risk of NSSI behavior ( OR =1.31, 95% CI =1.01-1.69, P <0.05). Compared with those without parent-child separation experiences, adolescents who were separated from their mother only ( OR =1.68, 95% CI =1.03-2.74) or from both parents ( OR =1.41, 95% CI =1.04-1.92) showed significantly increased risks of NSSI behavior (both P <0.05). Conclusions Parent-child separation experiences are associated with an increased risk of NSSI behavior among junior and senior high school students. Strengthened attention should be paid to left behind senior high school students to reduce the occurrence of NSSI in adolescents.

Objective:To investigate the therapeutic effects of fluticasone propionate combined with loratadine syrup and montelukast sodium on asthma and allergic rhinitis in children.Methods:A total of 119 children with asthma and allergic rhinitis, admitted to Department of Pediatrics, Dongyang Maternal and Child Health Hospital from March 2021 to March 2024, were selected for this retrospective study. Based on the different treatment methods recorded in the medical record system, the children were divided into two groups: the control group ( n = 70), which received loratadine syrup combined with montelukast sodium, and the observation group ( n = 49), which received fluticasone propionate combined with loratadine syrup and montelukast sodium. Clinical symptoms (rhinitis and asthma), serum markers (immunoglobulin E, interleukin-4, and interleukin-6), lung function (maximum peak expiratory flow rate, forced expiratory volume in the first second, forced expiratory flow at 25% of vital capacity, forced expiratory flow at 50% of vital capacity, forced expiratory flow at 75% of vital capacity), as well as adverse reactions and clinical efficacy, were observed and compared between the two groups. Results:After treatment, the symptom scores for both rhinitis and asthma in the observation group were significantly lower than those in the control group [(3.65 ± 0.88) vs. (4.55 ± 1.06), t = 4.88, P < 0.001; (2.15 ± 0.56) vs. (3.28 ± 0.89), t = 7.86, P < 0.001]. The levels of immunoglobulin E, interleukin-4, and interleukin-6 in the observation group were significantly lower than those in the control group [(0.31 ± 0.18) g/L vs. (0.42 ± 0.19) g/L, t = 3.18, P = 0.002; (56.83 ± 8.25) ng/L vs. (62.16 ± 9.94) ng/L, t = 3.08, P = 0.003; (32.48 ± 3.11) ng/L vs. (39.61 ± 4.72) ng/L, t = 9.26, P < 0.001]. The values for forced expiratory volume in the first second and forced expiratory flow at 25%, 50%, and 75% of vital capacity in the observation group were significantly higher than those in the control group [(87.18 ± 5.15)% vs. (84.36 ± 4.68)%, t = 3.10, P = 0.002; (89.35 ± 3.88)% vs. (83.25 ± 3.56)%, t = 8.86, P < 0.001; (74.36 ± 6.65)% vs. (65.25 ± 5.36)%, t = 8.26, P < 0.001; (71.68 ± 8.76)% vs. (65.35 ± 7.86)%, t = 4.12, P < 0.001; (69.24 ± 4.38)% vs. (65.35 ± 2.43)%, t = 6.20, P < 0.001]. The incidence of adverse reactions was significantly higher in the observation group than in the control group [8.16% (4/49) vs. 4.29% (3/70), χ2 = 0.60, P = 0.439]. The overall response rate was significantly higher in the observation group than in the control group [95.92% (47/49) vs. 82.86% (58/70), χ2 = 5.26, P = 0.022]. Conclusions:Fluticasone propionate combined with loratadine syrup and montelukast sodium can effectively alleviate symptoms in children with asthma and allergic rhinitis, improve serum indicators, enhance lung function, and increase clinical efficacy without substantially increasing adverse reactions, demonstrating high safety.

Objective To investigate the characteristics and correlation between peak oxygen uptake(VO?peak)and heart rate recov-ery(HRR)during cardiopulmonary exercise test(CPET)in patients with coronary borderline lesions.Methods From January,2022 to January,2024,183 patients with coronary borderline lesions in Beijing Bo'ai Hospital were divided into low cardiorespiratory fitness(LCF)group(n=61),moderate cardiorespiratory fitness(MCF)group(n=62)and high cardiorespiratory fitness(HCF)group(n=60)based on VO?peak.Their characteristics and CPET parameters including VO?peak,exercise-phase heart rate(HR1,HR2,HR3),and post-exercise heart rate recovery(HRR1,HRR2,HRR3)were analyzed.Results After adjusting for age and body mass index,analysis of covariance showed that the peak heart rate,HR1,HR2 and HR3 were the lowest in LCF group(F>5.388,P<0.01).Repeated-measures analysis of variance showed that the inter-and intra-group effects were significant in HRR(F>14.561,P<0.001).Partial correlation analy-sis showed that VO?peak positively correlated with HRR1(r=0.404,P<0.001),HRR2(r=0.379,P<0.001)and HRR3(r=0.425,P<0.001).Conclusion In patients with coronary artery borderline lesions,VO?peak demonstrated a significant inverse correlation with HRR,the lower the VO?peak,the more delays of HRR.

BACKGROUND: The optimal antidepressant dosages remain controversial. This study aimed to analyze the efficacy of antidepressants and characterize their dose-response relationships in the treatments of major depressive disorders (MDD). METHODS: We searched multiple databases, including the Embase, Cochrane Central Register of Controlled Trials, PubMed, and Web of Science, for the studies that were conducted between January 8, 2016, and April 30, 2023. The studies are double-blinded, randomized controlled trials (RCTs) involving the adults (≥18 years) with MDD. The primary outcomes were efficacy of antidepressant and the dose-response relationships. A frequentist network meta-analysis was conducted, treating participants with various dosages of the same antidepressant as a single therapy. We also implemented the model-based meta-analysis (MBMA) using a Bayesian method to explore the dose-response relationships. RESULTS: The network meta-analysis comprised 135,180 participants from 602 studies. All the antidepressants were more effective than the placebo; toludesvenlafaxine had the highest odds ratio (OR) of 4.52 (95% confidence interval [CI]: 2.65-7.72), and reboxetine had the lowest OR of 1.34 (95%CI: 1.14-1.57). Moreover, amitriptyline, clomipramine, and reboxetine showed a linear increase in effect size from low to high doses. The effect size of toludesvenlafaxine increased significantly up to 80 mg/day and subsequently maintained the maximal dose up to 160 mg/day while the predictive curves of nefazodone were fairly flat in different dosages. CONCLUSIONS: Although most antidepressants were more efficacious than placebo in treating MDD, no consistent dose-response relationship between any antidepressants was observed. For most antidepressants, the maximum efficacy was achieved at lower or middle prescribed doses, rather than at the upper limit.

OBJECTIVE: To investigate a case of antibodies against high-frequency erythrocyte antigens and elucidate the genetic mechanism underlying the blood group. METHODS: A Lan-negative patient referred to the Zhejiang Blood Center by Quzhou Hospital of Traditional Chinese Medicine in August 2016 was selected as the study subject. A retrospective study was conducted to collect the proband's clinical data. The proband's erythrocyte antigens and unexpected serum antibodies were identified using tube saline and microcolumn agglutination anti-human globulin methods. Antibody specificity was determined by treating erythrocytes with 7 enzymes and 2 chemical reducing agents. Genomic DNA was extracted from the proband's blood sample for whole genome sequencing (WGS) and erythrocyte blood group gene analysis, with validation by Sanger sequencing. Multiple bioinformatics tools were used to analyze the pathogenicity of the variant. The rare blood group and unexpected antibody specificity were comprehensively determined based on the results of serological and genetic testing. This study has been approved by the Zhejiang Provincial Blood Center Medical Ethics Committee(Ethics No.20190201). RESULTS: The proband was a 91-year-old Han Chinese male with prostatitis, cystitis, and malnutrition in conjunct with emaciation. He had a history of multiple erythrocyte transfusions without observable adverse reactions. Prior to the most recent transfusion, major crossmatch agglutination was observed, which prompted antibody identification. Antibodies against high-frequency antigens were detected in the proband's serum, with enzyme and reducing agent treatments ruling out antibody specificities associated with 17 blood group systems, e.g., MNS, LU, KEL. WGS analysis identified 4 525 SNPs and 1 046 INDEL variants among erythrocyte blood group genes. Further screening revealed that the proband had a rare blood group due to a homozygous rs755723161 variant. This variant in the ABCB6 gene (c.459delC) has led to a frameshifting mutation (p.Trp154GlyfsTer96), resulting in the Lan-negative rare blood group with a high-frequency antigen deficiency and the production of IgG anti-Lan antibodies in the serum. CONCLUSION This study has identified anti-Lan alloantibodies in a Lan-negative patient and, for the first time, elucidated the ABCB6 gene variant underlying the Lan-negative rare blood group in the Chinese population.

To analyze the clinical data and imaging examination data of a patient with metallic mercury poisoning from subcutaneous injection. The abdominal B-ultrasonograph results of the patient indicated multiple scattered hyperechoic spots accompanied by "comet tail" sign in the liver and right renal sinus, the nature of which was not clear and it was considered crystal deposition. The chest X-ray revealed scattered and multiple spot-like, snowflake-like and tree-cast-like high-density shadows in both lung fields. The chest computed tomography scan revealed multiple spot and patchy high-density shadows distributed in both lungs, considering hematogenous distribution deposits, and possible mercury poisoning. Laboratory test results showed that blood mercury level was 4.16 μmol/L and urine mercury level was 6 545.5 μg/g Cr. After 28 days of mercury chelation therapy, the abdominal ultrasound examination showed that the hyperechoic spots in the liver and right renal sinus were reduced compared with the previous examination. Metallic mercury poisoning from subcutaneous injection has specific manifestations in abdominal B-ultrasound imaging, which can provide a basis for the early diagnosis of metallic mercury poisoning in clinical practice and can be used to observe the efficacy of mercury chelation therapy.
