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.
2.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.

Polycystic ovary syndrome (PCOS) is one of the most prevalent gynecological diseases, and its incidence is increasing year by year, seriously affecting the physical and mental health of female patients. The pathogenesis of this disease is complex and has not been fully clarified. At present, PCOS is mainly treated by Western medicine, which, however, has poor efficacy and induces various adverse reactions. Therefore, developing safe and effective therapies has become a difficult problem that needs to be solved. Studies have confirmed that traditional Chinese medicine (TCM) can regulate phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt), mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK), Toll-like receptor 4/nuclear factor-κB (TLR4/NF-κB), transforming growth factor-β (TGF-β)/Smads, secreted glycoprotein/β-catenin (Wnt/β-catenin), adenosine monophosphate-activated protein kinase (AMPK), and advanced glycation endproduct/receptor for advanced glycation endproducts (AGE/RAGE) signaling pathways to ameliorate insulin resistance, inhibit inflammation and oxidative stress, regulate endocrine hormone disorders, and intervene in apoptosis and autophagy, thus alleviating the symptoms, slowing down the disease progression, and improving the ovarian function. The treatment of PCOS with TCM has demonstrated definite effects and high safety. Therefore, exploring this disease from cellular and molecular perspectives can provide a theoretical basis for its clinical treatment and new drug development. However, there is a lack of systematic reviews on the modulation of relevant signaling pathways by TCM in the treatment of PCOS. This article reviews the research progress in the treatment of PCOS with the active ingredients and compound prescriptions of TCM by regulating relevant signaling pathways in recent years, with the aim of providing evidence to support the promotion of TCM for treating PCOS in the future.

Objective:To evaluate the clinical efficacy, safety and treatment persistence of upadacitinib in Crohn's disease (CD) patients.Methods:The single-center retrospective cohort study was conducted. The patients with moderate-to-severe active CD initiating upadacitinib therapy from November 2023 to November 2024 in Nanjing Drum Tower Hospital were collected through searching the electronic medical records and paper-based patient databases. The primary outcome was the clinical remission rate at week 12. Secondary outcomes included the clinical response rate at week 12; clinical response and remission rates at weeks 4, 24 and 48; biomarker (fecal calprotectin or C-reactive protein) remission rates at all time points; as well as endoscopic remission and response rates, treatment persistence and safety evaluation.Results:A total of 44 CD patients were included, comprising 24 males (54.5%) and 20 females (45.5%). The median age was 33 (25, 40) years. The baseline Crohn's disease activity index (CDAI) score was 260.5 (225.9, 550.0) points. Patients had previously received a median of 2 (1, 2) biologic treatments. All 44 patients completed the 12-week induction therapy. With a median follow-up of 30.00 (16.25, 46.25) weeks, the clinical remission rate was 50.0% (22/44) at week 12. The clinical remission rate, clinical response rate, and biomarker remission rate were 52.3% (23/44), 88.6% (39/44) and 72.7% (32/44) respectively at week 4, and the clinical response rate and biomarker remission rate were 88.6% (39/44) and 77.2% (34/44) respectively at week 12. The clinical remission rates, clinical response rates and biomarker remission rates evolved to 43.3% (13/30), 86.7% (26/30) and 80.0% (24/30) at week 24, and further to 44.4% (4/9), 77.8% (7/9) and 77.8% (7/9) at week 48. During the follow-up period, 13 CD patients completing endoscopic evaluation, endoscopic remission and response rates were 30.8% and 23.1% respectively. CD-related surgery rate was 4.5% (2/44). Safety analysis demonstrated that the overall adverse events rate was 56.8% (25/44) including 7 patients with serious adverse events. A total of 8 patients discontinued treatment, among which 3 were due to primary loss of response, 1 due to secondary loss of response, 2 due to drug-related adverse events alone, and 2 due to concurrent primary loss of response and adverse events. The Kaplan-Meier curve for treatment persistence showed that among 39 CD patients who achieved clinical response at week 12, the continued treatment rates were 90.3% at week 12 and 85.3% at week 24 of follow-up. Two patients (5.6%) received dose escalation of upadacitinib, both of whom achieved clinical remission.Conclusion:Real-world research data demonstrate that upadacitinib exhibits significant clinical efficacy and a favorable safety profile in the treatment of moderate-to-severe active CD patients with prior biologic exposure, and no new unexpected adverse events are identified.

Objective:To observe the changes of small airway parameters in patients with coal workers' pneumoconiosis in different disease stages by high resolution computed tomography (HRCT) , and analyze the correlation between them and the severity of the disease.Methods:From June 2016 to June 2023, 25 healthy volunteers and 71 untreated patients with coal worker's pneumoconiosis in the Fifth People's Hospital of Ningxia were selected as the research objects. The clinical and imaging data of the patients were collected, and the disease stages were performed according to the dust exposure history and high-kilovolt chest X-ray. The patients were divided into 4 groups: control group (25 cases) , coal workers' pneumoconiosis stage Ⅰ group (17 cases) , coal workers' pneumoconiosis stage Ⅱ group (32 cases) and coal workers' pneumoconiosis stage Ⅲ group (22 cases) . Quantitative chest HRCT parameters of each group were collected, including the square root of wall area at 10 mm inner perimeter (AWT-Pi10, Pi10) , airway wall thickness, airway wall volume, airway wall area percentage of the whole lung and the 5th, 6th, 7th and 8th level airways, and low attenuation area percentage (LAA%) of the whole lung. Pulmonary function indicators were collected, including forced expiratory volume in 1 second (FEV 1) and the percentage of its projected value [FEV 1 (%pred) ], the ratio of FEV 1 to forced vital capacity (FEV 1/FVC) and the percentage of its projected value[FEV 1/FVC (%pred) ]. One-way ANOVA or Kruskal-Wallis H test and Spearman rank correlation were used to analyze the difference and correlation. Results:Compared with control group, FEV 1, FEV 1 (%pred) , FEV 1/FVC and FEV 1/FVC (%pred) in stage Ⅱ and Ⅲ coal workers' pneumoconiosis groups were lower ( P<0.05) . In addition, the FEV 1 and FEV 1 (%pred) of the stage Ⅲgroup were lower than those of the stageⅡ group ( P<0.05) , and the FEV 1/FVC and FEV 1/FVC (%pred) of the stage Ⅲgroup were lower than those of the stage Ⅰgroup ( P<0.05) . Compared with stage Ⅰ group, Pi10 in stage Ⅲ group were increased ( P < 0.05) at the 6th and 8th level airways, and airway wall thickness and airway wall volume in the 6th, 7th and 8th level airways of stage Ⅲgroup increased ( P<0.05) . Correlation analysis showed that all pulmonary function indexes were negatively correlated with Pi10 of whole lung and the 6th, 7th and 8th level airways ( P<0.05) , all pulmonary function indexes were negatively correlated with airway wall thickness of the 7th and 8th level airways ( P<0.05) , and FEV 1/FVC (%pred) was negatively correlated with airway wall volume of the 7th and 8th level airways ( P<0.05) . FEV 1, FEV 1 (%pred) , FEV 1/FVC (%pred) were negatively correlated with percentage of airway wall area of whole lung and the 6th, 7th and 8th level airways ( P<0.05) . Conclusion:The quantitative airway parameters of coal workers' pneumoconiosis based on HRCT are correlated with pulmonary function indexes, which can reflect the severity of coal workers' pneumoconiosis.
