Attention deficit and hyperactive disorder (ADHD) is the most common neurodevelopmental disorder of childhood. It seriously impairs academic achievement, social interaction, and vocational development, and increases the risk of accidental injury and substance abuse. In some cases, the symptoms may also exert an indirect disruptive effect on public order. Its aetiology involves interactions among genetic, perinatal environmental, and psychosocial factors that cannot be fully disentangled by single clinical studies. Therefore, a systematic evaluation of existing animal models is essential for revealing pathophysiology and developing novel therapies. Using the keywords "attention deficit and hyperactive disorder", "models, animal", "validity", and their English equivalents, we systematically searched PubMed, Web of Science, CNKI, and Wanfang for publications from 2000 to 2025 (retrieving 328 publications) and added further references by citation tracking. Eighty-six rodent ADHD models that provided detailed construction protocols, behavioural assessments, neurobiological mechanisms, or pharmacological data were included and classified into spontaneous genetic, genetically engineered, and environmentally induced paradigms. Their face, construct, and predictive validity were compared. Among spontaneous genetic models, spontaneously hypertensive rats reproduce hyperactivity, impulsivity, and stimulant responses well, yet hypertension and sex differences limit specificity. Acallosal mouse strains link corpus callosum absence to ADHD-like behaviours, but neurotransmitter studies remain scarce. Genetically engineered rodents—including dopamine transporter, neurokinin-1 receptor and mediator complex subunit 23 knockout or conditional gene knockout lines—precisely dissect dopaminergic, noradrenergic, synaptic, or epigenetic pathways, yet generally lack full phenotypic coverage, social-deficit modelling, and comorbidity representation, and are accompanied by adverse effects such as growth retardation or ocular defects. Environmentally induced models employ lead, polychlorinated biphenyls, alcohol, nicotine exposures, 6-hydroxydopamine lesions, neonatal hypoxia, early social isolation, or maternal stress to recapitulate core symptoms. However, dose-schedule standardisation is lacking. Behavioural reversibility diverges from clinical persistence, and non-specific phenotypes such as anxiety or depression are common. Overall, no single paradigm simultaneously achieves high validity across all three dimensions. Currently, ADHD models have progressed from single-factor simulations to multidimensional evaluation, yet significant gaps remain in genetic-background standardisation, sex differences, cross-species translation, and syndrome-differentiation modelling under traditional Chinese medicine. Future directions should integrate genetic, environmental, and epigenetic interactions, establish life-span validation systems, and incorporate computational neuroscience alongside integrative Chinese-Western strategies to enhance clinical relevance and translational utility, thereby providing robust evidence-based support for mechanistic elucidation, drug screening and precision intervention in ADHD.

Animal experimentation constitutes a critical link between basic research and clinical application, making its research quality and translational efficiency paramount. Although considerable progress has been made in standardizing operational procedures and ethical guidelines, the standardization of outcome evaluation systems has significantly lagged, creating a key bottleneck that constrains the quality of biomedical research and evidence synthesis. This deficiency is manifested by pronounced heterogeneity in outcome selection across similar studies, incomplete methodological reporting, and disparate criteria for result interpretation, which severely impairs the comparability of findings and the evidence integration. To cope with this challenge, this paper systematically introduces a mature methodological tool from clinical research–the core outcome set (COS)–and explores its construction strategies and application potential in the field of animal experimentation. Given the extensive diversity of animal experiments, a pragmatic strategy of "focusing on key areas, implementing phased pilots, and promoting gradual expansion" should be adopted. This approach prioritizes the development of domain-specific COS for disease areas characterized by high research volume, urgent translational needs, and well-established animal models. A multi-source integration pathway for COS development is detailed, comprising systematic literature searches, methodological appraisals, and expert consensus, with the feasibility of leveraging artificial intelligence (AI) to enhance efficiency also being examined. The development and promotion of such COS are not intended to restrict scientific exploration; rather, they aim to establish a new, tiered evaluation paradigm consisting of "core outcomes" (mandatory), "recommended outcomes" (encouraged), and "exploratory outcomes" (optional). This framework is expected not only to enhance research quality through standardization and to adhere to the "3R" principles but also to accelerate the accumulation of high-quality evidence. This, in turn, provides a solid foundation for higher-level evidence synthesis, ultimately facilitating the effective translation of basic research findings into clinical practice and providing an essential methodological framework for scientific advancement in relevant disciplines.
3.LUBAC-OTULIN Axis and Rare Autoinflammatory Diseases
JOURNAL OF RARE DISEASES 2026;5(1):73-81
The linear ubiquitin chain assembly complex (LUBAC), composed of heme-oxidized IRP2 ubiquitin ligase 1-interacting protein (HOIP), haem-oxidized IRP2 ubiquitin ligase-1(HOIL-1), and SHANK-associated RBCK1 homology-domain-interacting protein (SHARPIN), and its specific deubiquitinating enzyme OTULIN, regulates the dynamic balance of Met1-linked linear ubiquitination and maintains ubiquitin signaling homeostasis. Their precise interaction plays a central role in the regulation of nuclear factor-κB (NF-κB) and type I interferon signaling, inflammatory response, and cell survival and death. Dysregulation of the LUBAC-OTULIN axis can lead to aberrant immune and inflammatory signaling, immunodeficiency, and dysregulation of receptor-interacting protein kinase 1-mediated apoptosis or necroptosis. Genetic defects in OTULIN and LUBAC are associated with rare autoinflammatory diseases such as OTULIN-related autoinflammatory syndrome (ORAS) and HOIP/HOIL-1/SHARPIN deficiency, respectively, with complex clinical phenotypes and gene dose correlation. Current treatments primarily rely on glucocorticoids and tumor necrosis factor inhibitors, and hematopoietic stem cell transplantation has shown potential curative value in some patients with severe ORAS. This review summarizes the molecular composition, interaction mechanisms, and pathogenic roles of the LUBAC-OTULIN axis in rare autoinflammatory diseases, providing reference for the development of targeted therapeutic strategies.

Osteoporosis is a systemic disease, and epidemiological projections indicate that by 2050, approximately 23.43% of the Chinese population over 50 years of age will be affected. Given the poor prognosis associated with osteoporosis, the exploration of safe and effective natural products is of considerable significance. Studies investigating the chemical constituents of traditional Chinese medicine in cellular and/or animal models have demonstrated bone-protective effects. Although most of these compounds lack clinical data, they hold considerable potential as lead candidates for drug development. In-depth study of the structure-activity relationship of these natural products not only contributes to elucidating the mechanisms of action but also provides a theoretical basis for the development of novel antiosteoporosis therapies. This review summarizes natural products with potential antiosteoporotic effects reported between 2020 and 2024. Overall, plant-derived natural compounds exhibit antiosteoporotic effects by regulating bone remodeling, inflammation, and oxidative stress, highlighting their promise as multitarget therapeutic candidates.

Objective To construct a lung cancer surgery-oriented disease-specific database covering the entire perioperative care pathway, thereby improving the quality and usability of key surgical data elements. Methods Real-world clinical data were extracted from a single-center thoracic surgery department. A standardized data model was established based on the open electronic health record (openEHR) standard. Large language model (LLM), optical character recognition (OCR), and artificial intelligence (AI)-driven techniques were employed to extract, structure, and perform quality control on unstructured clinical narratives, imaging reports, and radiological data, with a focus on capturing surgically relevant perioperative indicator. Results A multimodal database comprising 19 917 patients was established, including 7 930 males and 11 987 females, with ages ranging from 15 to 97 (61.7±9.7) years. The database includes 582 structured data variables, textual report data corresponding to 69 clinical indicators, 13 000 pulmonary function test PDF reports, and chest CT imaging data from 16 884 patients. This database comprehensively covers major information relevant to surgical diagnosis and treatment of lung cancer, significantly improving the completeness and granularity of surgical detail data. Large language models (LLMs) and optical character recognition (OCR) technologies enhanced the efficiency of converting unstructured data into structured formats, while a multi-level manual verification process ensured data accuracy and traceability. The database supports real-world research including comparisons of surgical procedures, prediction of postoperative complications, prognosis assessment, and multimodal data association analyses.

ObjectiveTo explore the effect and mechanism of modified Dingjingtang in regulating the Toll-like receptor 2 (TLR2)/nuclear factor (NF)-κB/NOD-like receptor protein 3 (NLRP3) signaling pathway to inhibit inflammatory skin lesions in the rat model of acne. MethodsForty-eight rats were randomized into the normal, model, low-, medium-, and high-dose (8.1, 16.2, and 32.4 g·kg-1) modified Dingjingtang, and doxycycline hydrochloride (0.27 g·kg-1) groups, with 8 rats in each group. Rats in other groups except the normal group were modeled by intradermal injection and intraperitoneal injection of Propionibacterium acnes. After successful modeling, rats in the intervention groups were treated with corresponding agents by gavage, and those in the normal and model groups with an equal volume of normal saline, once a day for 14 consecutive days. Then, the samples were collected. The general conditions, ear thickness, and body weight changes of rats were observed. Biochemical methods were used to determine superoxide dismutase (SOD) and malondialdehyde (MDA) levels in the ear tissue. Hematoxylin-eosin staining and Masson's staining were used to observe the pathological changes and collagen deposition, respectively, in the ear tissue. Immunohistochemistry was employed to determine the interleukin (IL)-1β level in the ear tissue. Enzyme-linked immunosorbent assay was adopted to measure the levels of IL-1β, tumor necrosis factor (TNF)-α, and IL-6 in the serum. The total antioxidant capacity method was adopted to assess the reactive oxygen species (ROS) content in the ear tissue. Western blot and real-time fluorescence quantitative polymerase chain reaction were employed to determine the protein and mRNA levels, respectively, of TLR2, myeloid differentiation factor 88 (MyD88), NF-κB, NLRP3, and cysteinyl aspartate-specific proteinase-1 (Caspase-1) in the ear tissue. ResultsCompared with the normal group, the model group had increased ear skin thickness (P<0.01), elevated ROS and MDA levels (P<0.01), reduced SOD content (P<0.05), and increased collagen deposition (P<0.01) in the ear tissue. In addition, the model group showed raised IL-1β, IL-6, and TNF-α levels in the serum (P<0.01) and up-regulated mRNA and protein levels of TLR2, MyD88, NF-κB, NLRP3, and Caspase-1 (P<0.01). Compared with the model group, the high- and medium-dose modified Dingjingtang groups showed significant improving effects regarding the above indicators (P<0.05, P<0.01). ConclusionModified Dingjingtang can ameliorate the inflammatory skin lesions in the rat model of acne by regulating the TLR2/NF-κB/NLRP3 signaling pathway.

Objective:
This study compares the effects of lithium disilicate glass ceramic onlays and full crowns in restoring cracked teeth that have undergone root canal therapy, providing a reference for the restoration method of cracked teeth that have undergone root canal therapy.
Methods:
This study was approved by the hospital’s medical ethics committee, and all patients signed the informed consent form. Patients with cracked teeth who underwent root canal treatment in our hospital from January 2022 to January 2023 were enrolled in this study. According to the inclusion and exclusion criteria, 60 patients were screened and enrolled, with a total of 60 affected teeth. The patients were divided into the onlay group and full crown group at a ratio of 2:3 using the random number table method. Lithium disilicate glass ceramic onlays were used to restore the affected teeth in the onlay group (24 cases), and lithium disilicate glass ceramic full crowns were used to restore the affected teeth in the full crown group (36 cases). At 3, 6, and 12 months after the repair, the restoration effect was evaluated and compared with the modified USPH Standard (the aesthetic, functional, and biological aspects of restorations). According to the biological definition of survival, survival analysis was conducted on the affected teeth in both groups.
Results:
At 3, 6, and 12 months after the repair, 85% of cases in the onlay group achieved grade A, while 80% of cases in the full crown group achieved grade A. There was no statistically significant difference in the restoration effects between the onlay group and the full crown group (P > 0.05). The 12-month survival rate of cracked teeth in the onlay group reached 95.65%, and the 12-month survival rate of cracked teeth in the full crown group reached 94.12%. There was no statistically significant difference in the retention of the affected teeth (P > 0.05). There was no significant effect of age, gender, tooth position, dentition, direction of cracks, the number of marginal ridges associated with cracks, or the type of restoration on the survival status of cracked teeth. (P > 0.05).
Conclusion
For cracked teeth that have undergone root canal therapy, the short-term effect of lithium disilicate glass ceramic onlays is comparable to that of full crowns, and both have good short-term effects. Onlays are less invasive and are expected to become an alternative restoration method to full crowns.

Objective To investigate negative mental and behavior problems in children with short stature and analyze their relationship with family function and quality of life. Methods A total of 347 cases of children with dwarfism received from 358 cases in Chengdu Jingjiang Hospital for Women and Children Health from January 2019 to December 2023 were selected as the dwarfism group were included in this study. The two groups were compared on negative mental and behavior problems [Mental Health Scale for Child and Adolescent (MHS-CA)], family function [Family Adaptability and Cohesion Evaluation Scale II-Chinese Version (FACES II-CV)] and quality of Life [Pediatric Quality of Life Inventory 4.0 (PedQL4.0)]. Correlation analysis was performed. Results MHS-CA scores, FACES II-CV scores and PedQL4.0 scores of the short stature group were lower than those of the control group (P<0.05). With MHS-CA score ≤ 57 as the critical value, 347 children with short stature were divided into healthy state group (256 cases) and unhealthy state group (91 cases). FACES II-CV scores and PedsQL4.0 scores of children in unhealthy state were lower than those of children in healthy state (P<0.05). Pearson correlation analysis found that mental health problems were positively correlated with family function and quality of life in children with short stature (r=0.217, 0.386, both P=0.000). Conclusion Mental health problems in children with short stature are significantly positively correlated with family function and quality of life.

Diabetic cataract, a prevalent ocular complication of diabetes mellitus, arises from a complex interplay of pathological mechanisms, with oxidative stress and glycation stress playing central roles. Autophagy, a critical cellular self-protection mechanism, sustains intracellular homeostasis by selectively degrading damaged organelles and misfolded proteins, thereby counteracting the detrimental effects of oxidative and glycation stress under hyperglycemic conditions. Emerging evidence indicates a synergistic interaction between glycation stress and oxidative stress, which may exacerbate autophagic dysfunction and accelerate the onset and progression of diabetic cataract. However, the precise molecular mechanisms underlying this relationship remain incompletely understood. This review systematically examines the regulatory role of autophagy inthe pathogenesis of diabetic cataract, with a particular focus on how autophagic impairment influences disease progression under the combined effects of glycation and oxidative stress. By elucidating these mechanisms, the paper aims to provide novel insights into molecular diagnostic approaches and targeted therapeutic strategies for diabetic cataract.
