Objective:
To explore the latent profile characteristics of regulatory emotional self-efficacy and its relationship with non-suicidal self-injurious (NSSI) behavior among junior and senior high school students, so as to provide a basis for effectively reducing NSSI behaviors.
Methods:
From April to October 2023, a total of 1 217 junior and senior high school students were selected from Tongren City, Zunyi City and Qiannan Prefecture of Guizhou Province by stratified cluster random sampling method. The Scale of Regulatory Emotional Self-efficacy and the Adolescent Self-injury Scale were administered. Latent profile analysis (LPA) was employed to explore distinct profiles of regulatory emotional self-efficacy, and the Lanza, Tan, and Bray s method (LTB) was used to analyze the relationship between these profiles and NSSI behavior.
Results:
The prevalence rate of NSSI behavior among junior and senior high school students was 28.6%. Among males, regulatory emotional self-efficacy was categorized into two types: moderate positive expression-low negative management group (59.1%, n =353) and high efficacy group (40.9%, n =244); among females, regulatory emotional self-efficacy was classified into three categories: low efficacy group (18.4%, n =114), high positive expression-low negative management group (56.3%, n =349), and high efficacy group (25.3%, n =157). There were statistically significant differences in total NSSI scores across different potential categories of regulatory emotional self-efficacy within both males and females ( Z/H = -5.75 , 57.58, both P <0.01). The differences in NSSI prevalence rates across the potential categories of regulatory emotional self-efficacy were statistically significant for both males and females ( χ 2=38.00, 69.14, both P <0.01), and among females, the differences in NSSI prevalence rates between the high efficacy group and the low efficacy group ( χ 2=60.01) and between the high efficacy group and the high positive expression-low negative management group ( χ 2=31.34) were also statistically significant (both P < 0.016 7 ). Binary Logistic regression analysis revealed that, compared with the high efficacy group within each gender, the moderate positive expression-low negative management group among males ( OR =2.36), and both the low efficacy group and the high positive expression-low negative management group among females ( OR =6.19, 2.97), were at an increased risk of engaging in NSSI (all P <0.01).
Conclusion
Different latent profiles of regulatory emotional self efficacy among junior and senior high school students are associated with NSSI behavior.

ObjectiveTo investigate the efficacy and safety of Kaixuan Jiedu compatibility and the decomposed prescriptions in the treatment of psoriasis. MethodsThirty Balb/c mice were randomly grouped as follows (n=6): normal, model, Kaixuan Jiedu (KXJD, 15.21 g·kg-1), Kaixuan (KX, 3.08 g·kg-1), and Jiedu (JD, 12.13 g·kg-1). Except the normal group, the rest groups were modeled for psoriasis-like skin lesions by topical application of imiquimod, and samples were collected after 7 days of continuous intervention. Mice were photographed at the lesion site during modeling and before sampling and the psoriasis area and severity index (PASI) was calculated. Hematoxylin-eosin (HE) staining was used to observe pathological changes in the lesions and measure the epidermal thickness. Mice were photographed and observed for the tortuous dilation of dermal capillaries. The expression of vascular endothelial growth factor (VEGF), platelet-endothelial cell adhesion molecule (CD31), proliferating cell nuclear antigen (Ki67), and cytokeratin 10 (CK10) in the epidermal tissue was detected by immunohistochemistry. Immunofluorescence assay was employed to determine the expression of Claudin-1 and Occludin. Real-time PCR was employed to determine the mRNA levels of interleukin-17A (IL-17A) and interleukin-23 (IL-23). The spleen and thymus were photographed and weighed, and the spleen and thymus indices were calculated. The safety of the treatment was assessed by automatic biochemistry testing of the serum, liver, and kidney functions and by HE staining of the liver, kidney and spleen. ResultsCompared with that of the normal group, the skin of the model group showed erythema, infiltration, and typical psoriasis-like changes, tortuous dilation of dermal capillaries, hyperkeratosis in epidermal cells, acanthosis, massive lymphocytic infiltration in the dermis, impaired barrier function, increased expression of VEGF, CD31, Ki67, and CK10 (P<0.01), reduced expression of Claudin-1 and Occludin (P<0.01) in the epidermis, and up-regulated mRNA levels of IL-17A and IL-23 (P<0.01). In addition, the mice in the model group showed spleen enlargement, thymus atrophy, increased spleen index, and decreased thymus index (P<0.01). Compared with the model group, KXJD and JD reduced psoriasis-like skin lesions, inhibited the tortuous dilation of dermal capillaries, reduced the expression of VEGF, CD31, Ki67, and CK10 (P<0.01), increased the expression of claudin-1 (P<0.01), and down-regulated the mRNA levels of inflammatory factors (P<0.01). Moreover, the KXJD group outperformed the JD group. The JD group showed no significant difference from the model group regarding the spleen index, thymus index, and Occludin expression. The psoriasis indicators in the KX group were not significantly different from those in the model group. ConclusionKXJD and JD can reduce the symptoms of local skin lesions of psoriasis, which is manifested as different inhibition degrees of the proliferation and differentiation of keratin-forming cells, tortuous dilation of dermal capillaries, and inflammatory reactions, as well as the protection of the skin barrier. Moreover, KXJD outperformed JD. KX alone did not significantly reduce psoriasis lesions in mice. KXJD and the decomposed prescriptions are safe and effective, causing no obvious liver and kidney injuries.

A novel fumigation moxibustion device has been designed to enable adjustable and controllable moxa smoke temperature, maintaining a relatively stable fumigation temperature while improving the utilization efficiency of moxa smoke. The device consists of five main components: a temperature control chamber, fumigation outlet, temperature measurement module, moxa smoke filtration chamber, and elastic band. It is compact, refined, and easy to operate. The device allows users to set the desired fumigation temperature according to therapeutic needs and simultaneously filters and eliminates residual moxa smoke after treatment. This design addresses the challenges of traditional fumigation moxibustion therapy, including unstable moxa smoke temperature, difficulty in regulation, low utilization efficiency, and high dependence on manual operation. It contributes to the promotion and application of fumigation moxibustion therapy and supports the establishment of a standardized moxibustion system.

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.

Objective:To integrate implicit templates with deep learning techniques, a novel neural network, the tooth-deformable deep implicit network (T-DDIN), was constructed to achieve high-precision shape completion of tooth defects in a personalized manner.Methods:A total of 550 intraoral scan models were collected from patients treated at the Department of Orthodontics and Department of Prosthodontics, West China Hospital of Stomatology, Sichuan University (500 for training and 50 for testing), between March 2022 and March 2024. T-DDIN reconstructed defective tooth morphology using an implicit template and a latent encoding prediction network. During model evaluation, Class Ⅱ cavity defects and occlusal wear defects were simulated in the test set. Morphological restoration was performed using both traditional computer aided design (CAD) methods and the T-DDIN deep learning approach. The two methods were compared based on three-dimensional deviation, occlusal adjustment volumes, cusp angle deviation, and restoration time.Results:The T-DDIN group demonstrated significantly lower three-dimensional deviation for Class Ⅱ cavity defects and occlusal wear restoration [(0.14±0.05) and (0.16±0.09) mm], occlusal adjustment volumes [(0.44±0.03) and (0.49±0.03) mm 3], and difference value of the tooth cusp angles (5.69°±1.90° and 6.04°±0.53°) compared to the traditional CAD group (both P<0.001). No significant differences were observed within the T-DDIN group between the two defect types in terms of three-dimensional deviation ( P=0.098) or occlusal adjustment volume ( P=0.154) or difference value of the tooth cusp angles ( P=0.196). However, in the traditional CAD group, three-dimensional deviation, occlusal adjustment volume and difference value of the tooth cusp angles was significantly higher in occlusal wear restorations than in Class Ⅱ cavity defects restorations ( P<0.001). The T-DDIN group, which involved Class Ⅱ cavity defects and occlusal wear, demonstrated significantly less recovery time of morphology (37.2±7.7) and (39.4±6.2) s compared to the traditional CAD group ( P<0.001). Conclusions:T-DDIN demonstrated superior stability and accuracy in morphological reconstruction for various types of dental defects while significantly reducing restoration time.
