BackgroundNon-suicidal self-injury (NSSI) behavior has become a global public health concern affecting the physical and mental health of adolescents. The experiential avoidance model posits that childhood trauma contributes to NSSI behavior through the mediating pathway of emotional dysregulation. However, existing research has predominantly focused on isolated psychological or social factors, with limited attention to their interactive effects of emotional dysregulation and social anxiety, both of which fall within the psychosocial domain. ObjectiveTo examine the relationship between childhood trauma and NSSI among adolescents, and to analyze the mediating role of emotional dysregulation and the moderating role of social anxiety, so as to provide evidence for targeted interventions for NSSI behavior of adolescents. MethodsA total of 282 adolescent inpatients who consecutively admitted to the Department of Psychiatry of Guangdong Provincial People's Hospital from March to December 2025 and met the Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)criteria for NSSI were enrolled as study participants. Participants were assessed using the general information questionnaire, the Adolescent Self-Harm Questionnaire, the Childhood Trauma Questionnaire (CTQ), the Difficulties in Emotion Regulation Scale (DERS), and the Social Anxiety Scale for Adolescents (SAS-A). Pearson correlation analysis was used to examine correlations among scale scores. model 4 and model 58 of the Process 4.1 were used to test the mediating effect of emotional dysregulation and the moderating effect of social anxiety, respectively. ResultsCTQ score was positively associated with score of the Adolescent Self-Injury Questionnaire (r=0.279, P<0.01). Emotional dysregulation significantly partially mediated the relationship between childhood trauma and NSSI behavior, with a mediating effect of 0.112 (95% CI: 0.043–0.208), accounting for 40.14% of the total effect. Social anxiety moderated the association between childhood trauma and emotional dysregulation,the effect value was 0.102 (95% CI: 0.008–0.196), as well as the relationship between emotional dysregulation and NSSI behavior, the effect value was 0.130 (95% CI: 0.033–0.226). ConclusionEmotional dysregulation may mediate the relationship between childhood trauma and NSSI behavior among hospitalized adolescents, while social anxiety moderates both the first and second paths of this mediating process.

This study analyzed the epidemiological characteristics and strain genotypic distribution of varicella in Fengtai District, Beijing, utilizing population-based surveillance data from March 2024 to February 2025 combined with laboratory nucleic acid detection and genotyping.We reported 522 varicella cases with male predominance (282 cases, 54.41%) and a majority aged >15 years (358 cases, 68.58%).A bimodal incidence pattern peaked in May and November, while 161 breakthrough infections (30.8%) occurred predominantly among students aged 6-20 years.The multivariate logistic regression model analysis showed that, compared to the 0-5 years age group, individuals aged 6-14 years ( OR: 2.729, 95% CI: 1.083-6.88), 15-20 years ( OR: 2.495, 95% CI: 1.158-5.378), and>20 years ( OR: 5.382, 95% CI: 2.478-11.689) exhibited progressively higher odds of oderate-to-severe rash; females demonstrated a lower risk compared to males ( OR: 0.485, 95% CI: 0.286-0.822); regarding vaccination status, recipients of one vaccine dose ( OR: 0.301, 95% CI: 0.161-0.564) and two doses ( OR: 0.203, 95% CI: 0.086-0.48) showed significantly reduced risks relative to unvaccinated individuals. Genotyping of 174 specimens identified 161 VZV-positive samples, with successful ORF22/38/62 sequencing in 142 samples confirming Clade 2 predominance (141 strains, 99.3%) and one Clade 5 strain; local isolates exhibited high vaccine-strain homology (ORF22 nucleotide:99.5%-100%, amino acid:99.3%-100%) with mutation sites partially overlapping other Chinese regions.

Surface guided radiation therapy (SGRT) is a non-radiation, non-invasive technology that provides continuous postural monitoring of patients during radiotherapy. Using advanced 3D optical surface localization and tracking technology, SGRT quickly captures the surface contour information of patients through optical means to generate high-precision 3D surface contours, enabling real-time monitoring of patients during radiotherapy to ensure its accuracy. This image-guided technology has been widely applied in radiotherapy for tumors in different parts of the body, such as breast, intracranial, head and neck, and limbs. SGRT can reduce initial setup errors and provide real-time monitoring during treatment, or be combined with respiratory gating and deep inspiration breath-hold techniques. SGRT can also reduce radiation dose by reducing the use of CBCT, improve patient comfort with the use of immobilization devices, and enhance clinical speed, efficiency, and safety. This review aims to provide an overview of the commonly used technology and clinical applications of SGRT, and discuss its current limitations and future prospects.

Mitophagy is a process whereby cells selectively remove mitochondria through the mechanism of autophagy, which plays an important role in maintaining cellular homeostasis. In order to explore the effect of mitophagy genes on the antioxidant activities of Saccharomyces cerevisiae, mutants with deletion or overexpression of mitophagy genes ATG8, ATG11 and ATG32 were constructed respectively. The results indicated that overexpression of ATG8 and ATG11 genes significantly reduced the intracellular reactive oxygen species (ROS) content upon H2O2 stress for 6 h, which were 61.23% and 46.35% of the initial state, respectively. Notable, overexpression of ATG8 and ATG11 genes significantly increased the mitochondrial membrane potential (MMP) and ATP content, which were helpful to improve the antioxidant activities of the strains. On the other hand, deletion of ATG8, ATG11 and ATG32 caused mitochondrial damage and significantly decreased cell vitality, and caused the imbalance of intracellular ROS. The intracellular ROS content significantly increased to 174.27%, 128.68%, 200.92% of the initial state, respectively, upon H2O2 stress for 6 h. The results showed that ATG8, ATG11 and ATG32 might be potential targets for regulating the antioxidant properties of yeast, providing a new clue for further research.
