Objective:To explore the status of psychological resilience in female infertility patients and analyze its influencing factors, providing a basis for developing effective intervention measures in clinical practice.Methods:A convenient sampling method was used to select female infertility patients who visited the Reproductive Medicine Center of the First Affiliated Hospital of the University of South China from March to October 2024 as the research objects. A cross-sectional survey was conducted using the General Data Questionnaire, Connor-Davidson Resilience Scale, Herth Hope Index, the Infertility Stigma Scale, Family Resilience Scale and Perceived Social Support Scale. The random forest algorithm was used to rank the importance of variables, Lasso regression was used to further screen variables, and the selected variables were included in multiple stepwise regression analysis to analyze the influencing factors.Results:Ultimately, 322 female infertility patients aged (30.40 ± 4.50) were included. The psychological resilience score was (64.29 ± 10.05) points, which was above the medium level. The top 6 influential factors in the importance of variables were stigma, family resilience, age, social support, infertility cause and hope level. Multiple stepwise regression analysis showed that age, infertility cause, hope level, stigma, family resilience and social support were the main influencing factors of mental resilience of female infertility patients ( t values were -8.32 to 6.85, all P<0.05). Conclusions:The psychological resilience of female infertility patients is above the medium level, and the psychological resilience of infertile women is affected by many factors such as individual characteristics, family environment and social support. Medical staff should take targeted intervention measures to improve the psychological resilience of female infertility patients.

Objective:To explore the characteristics of social skills and problem behaviors of children and adolescents with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), as well as the association with core symptoms.Methods:A total of 409 patients aged 5-18 years old with ASD or ADHD in the outpatient department of Nanjing Brain Hospital from 2023 to 2024, and 344 children and adolescents with typical development(TD) were recruited.All participants were matched in a ratio of 1∶1∶1 (ASD∶ADHD∶TD) according to gender and age, and 97 participants were included in each group for analysis.The Chinese version of the social skills improvement system rating scales(SSIS-RS-C) was used to evaluate social skills and problem behaviors, and autistic child behavior checklist(ABC), childhood autism rating scale(CARS), the Chinese version of the social communication questionnaire(SCQ) and the Chinese version of Swanson, Nolan, and Pelham, version Ⅳ scale-parent form(SNAP-Ⅳ) were used to evaluate the core symptoms of ASD and ADHD, respectively. SPSS 26.0 software was used to perform variance, Chi-square test, Spearman correlation analysis and multivariate Logistic regression analysis.Results:The social skills score of ASD group was lower than ADHD group ((61.53±24.26) vs (80.89±15.19), P<0.05), while the problem behavior score of ASD group was higher than ADHD group ((38.82±11.92) vs (34.00±12.45), P<0.05). In ASD group, the scores of ABC, CARS and SCQ were negatively correlated with the score of social skills ( r=-0.26--0.55, P<0.05). In ADHD group, the total score and each subscale of SNAP-Ⅳ were positively correlated with the score of problem behavior ( r=0.25-0.65, P<0.05). Multivariate Logistic regression analysis showed that empathy was a negative influencing factor of ASD ( B=-0.246, OR=0.782, P<0.05), and hyperactivity/inattention was a positive influencing factor of ASD ( B=0.589, OR=1.802, P<0.01), while only hyperactivity/inattention was a positive influencing factor of ADHD( B=0.779, OR=2.180, P<0.01). Conclusion:Children and adolescents with ASD and ADHD both have defects in social skills and problem behaviors, and these defects are associated with the core characteristics of their respective diseases.

Objective:To analyze and validate the reliability and validity of the social skills improvement system-rating scales Chinese version (parent version) (SSIS-RS-C) in middle school students.Method:A total of 1 486 parents of middle school students were recruited according to the cluster sampling method.The social responsiveness scale and strengths and difficulties questionnaire were used as criterion validity tools.A retest was conducted one month later.SPSS 27.0 was used for descriptive statistics, item analysis, internal consistency test, test-retest reliability test and criterion validity test. AMOS 24.0 was used to perform confirmatory factor analysis .Results:Item analysis indicated significant positive correlations between each item and the subscales ( r=0.293-0.782, all P<0.01), with significant differences in scores between high and low groups ( t=10.079-37.038, all P<0.01).Confirmatory factor analysis supported a seven-factor structure for the social skills subscale(communication, cooperation, assertion, responsibility, empathy, engagement and self control) and a five-factor structure for the problem behavior subscale (externalizing, bullying, hyperactivity/inattention, internalizing and autism spectrum) of the SSIS-RS-C.There was a positive correlation between the social skills subscale and prosocial behavior ( r=0.637, P<0.001), and between the problem behavior subscale and social impairments and difficult behaviors ( r=0.765, 0.688, both P<0.001).The Cronbach's α coefficients for the total scale, social skills subscale and problem behavior subscale were 0.934, 0.972 and 0.963, respectively.The test-retest correlation coefficients for the total score and the two subscales were 0.665, 0.871 and 0.598, respectively (all P<0.001). Conclusion:The SSIS-RS-C demonstrated good reliability and validity in the Chinese adolescent population.

BACKGROUND: Quantitative flow ratio (QFR) holds significant value in guiding drug-coated balloon (DCB) treatment and enhancing outcomes. However, the predictive capability of post-angioplasty QFR for long-term clinical events in patients with de novo lesions who receive DCB treatment remains uncertain. The aim of this study was to explore the potential significance of post-angioplasty QFR measurements in predicting clinical outcomes in patients underwent DCB treatment for de novo lesions. METHODS: Patients who underwent DCB-only intervention for de novo lesions were enrolled. QFR was conducted after DCB treatment. The patients were then categorized based on post-angioplasty QFR. The primary endpoint was major adverse cardiac events (MACE), encompassing all-cause death, cardiovascular death, nonfatal myocardial infarction, stroke, and target vessel revascularization. RESULTS: A total of 553 patients with 561 lesions were included. The median follow-up period was 505 days, during which 66 (11.8%) MACEs occurred. Based on post-procedural QFR grouping, there were 259 cases in the high QFR group (QFR > 0.93) and 302 cases in the low QFR group (QFR ≤ 0.93). Kaplan-Meier analysis revealed a significantly higher cumulative incidence of MACE in the low QFR group (log-rank P = 0.004). The multivariate Cox proportional hazards model demonstrated a significant inverse correlation between QFR and the occurrence of MACEs (HR = 0.522, 95%CI: 0.289-0.942, P = 0.031). Landmark analysis indicated that high QFR had a significant reducing effect on the cumulative incidence of MACEs within 1 year (log-rank P = 0.016) and 1-5 years (log-rank P = 0.026). CONCLUSIONS In patients who underwent DCB-only treatment for de novo lesions, higher post-procedural QFR values (> 0.93) were identified as an independent protective factor against adverse prognosis.

OBJECTIVE: To evaluate the anti-hepatocellular carcinoma (HCC) activity of total alkaloids from Gelsemium elegans Benth. (TAG) in vivo and in vitro and to elucidate their potential mechanisms of action through transcriptomic analysis. METHODS: TAG extraction was conducted, and the primary components were quantified using high-performance liquid chromatography (HPLC). The effects of TAG (100, 150, and 200 µg/mL) on various tumor cells, including SMMC-7721, HepG2, H22, CAL27, MCF7, HT29, and HCT116, were assessed. Effects of TAG on HCC proliferation and apoptosis were detected by colony formation assays and cell stainings. Caspase-3, Bcl-2, and Bax protein levels were detected by Western blotting. In vivo, a tumor xenograft model was developed using H22 cells. Totally 40 Kunming mice were randomly assigned to model, cyclophosphamide (20 mg/kg), TAG low-dose (TAG-L, 0.5 mg/kg), and TAG high-dose (TAG-H, 1 mg/kg) groups, with 10 mice in each group. Tumor volume, body weight, and tumor weight were recorded and compared during 14-day treatment. Immune organ index were calculated. Tissue changes were oberseved by hematoxylin and eosin staining and immunohistochemistry. Additionally, transcriptomic and metabolomic analyses, as well as quatitative real-time polymerase chain reaction (RT-qPCR), were performed to detect mRNA and metabolite expressions. RESULTS: HPLC successfully identified the components of TAG extraction. Live cell imaging and analysis, along with cell viability assays, demonstrated that TAG inhibited the proliferation of SMMC-7721, HepG2, H22, CAL27, MCF7, HT29, and HCT116 cells. Colony formation assays, Hoechst 33258 staining, Rhodamine 123 staining, and Western blotting revealed that TAG not only inhibited HCC proliferation but also promoted apoptosis (P<0.05). In vivo experiments showed that TAG inhibited the growth of solid tumors in HCC in mice (P<0.05). Transcriptomic analysis and RT-qPCR indicated that the inhibition of HCC by TAG was associated with the regulation of the key gene CXCL13. CONCLUSION TAG inhibits HCC both in vivo and in vitro, with its inhibitory effect linked to the regulation of the key gene CXCL13.

Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.
