Binge eating disorder(BED)is a common eating disorder whose pathogenesis involves both neurobiological and psychological mechanisms.At the neurobiological level,the development of BED is associated with abnormal resting-state brain functional connectivity in the reward circuitry,dysregulation of the endocannabinoid system,and elevated leptin levels.This paper reveals that the neurobiological mechanisms of BED may influence psychological processes,including habitual behavioral imbalances and impaired emotion regulation.Conversely,the dysfunction of behavior in the psychological domain may further modulate neurobiological manifestations.This finding provides insights for future research aimed at systematically integrating neural mechanisms into clinical interventions,ultimately facilitating treatment advancement and prognostic improvement.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Trichotillomania, also known as Hair Pulling Disorder, is a unique obsessive-compulsive spectrum disorder characterized by repeated removal of hair from various parts of the body. Patients attempt to control this behavior but often fail, causing impairment to important functional areas such as social interaction, work, and academics. Trichotillomania typically begins in childhood or adolescence, and is often comorbid with anxiety and depression. The resulting physical damage and changes in appearance further exacerbate the social functional impairment of patients, resulting in most patients being diagnosed only in adulthood, and missing the optimal intervention period. Current pharmacological treatments for Trichotillomania are not satisfactory, while various psychological therapies have shown potential value and prospects. Therefore, this article focuses on Trichotillomania in children and adolescents, providing a comprehensive review from multiple aspects including disease diagnosis, clinical characteristics and typing, functional impairment, neuroimaging mechanisms, and the latest developments in psychological therapy, to provide references for the clinical diagnosis, assessment, and effective intervention of Trichotillomania.

Alexithymia refers to a deficiency of emotional structure, but the neurologic and psychological mechanisms of non-suicidal self-injury (NSSI) in adolescents are still unclear. The neural basis of alexithymia may play a role in adolescents′ NSSI by affecting the function of emotion regulation and emotion expression. At the same time, NSSI is also considered to be a non-adaptive emotional regulation mode for alexithymia individuals, which interacts with personality factors and psychosocial factors. This study explored the neuropsychological mechanism of alexithymia in adolescent NSSI from the perspective of emotional function, and provided theoretical basis for early identification and precise intervention of alexithymia and adolescent NSSI.

At present, although many burn centers and treatment units in China have established burn intensive care units (ICU), due to their limited capacity, the sudden nature of burn accidents, and the gradual transformation of professional burn treatment team, more and more critically burned patients are mainly treated in comprehensive ICU. The comprehensive ICU has been gradually adopting a semi-open management mode, with multidisciplinary collaboration led by ICU or burn specialists for critical burn treatment. Based on clinical practice, this paper shares the experience of treating critical burns under a semi-open management mode led by the burn department in comprehensive ICU, briefly introduces the strategies for capacity management and experience of infection prevention and control in the course of critical burns, and explores the mode of comprehensive ICU led by the burn department in treating critical burns, so that the burn surgeon can better treat critical burns by combining burn treatment experience and modern technologies of critical monitoring, diagnosis and treatment.
