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.

Licochalcone E is a chalcone isolated from Glycyrrhiza uralensis and G. inflata Batal. This study explored the effect of licochalcone E on improving hepatic steatosis in obese mice and evaluated the role of licochalcone E in regulating lipid accumulation in hepatocytes. In vitro, oleic acid–induced hepatocytes were treated with licochalcone E to investigate its effect on lipid metabolic pathways. In animal experiments, male C57BL/6 mice were fed with a high-fat diet (HFD) and treated with licochalcone E by intraperitoneal injection for 12 weeks to assess its effects on biochemical indexes and hepatic steatosis. Furthermore, mice were fed a methionine/choline-deficient (MCD) diet and administered licochalcone E, followed by evaluation of liver fibrosis. Licochalcone E effectively reduced body weight, epididymal and inguinal fat weight, and adipocyte size in HFD-induced obese mice. Licochalcone E treatment of obese mice also reduced hepatic lipid accumulation and improved hepatocyte steatosis. Licochalcone E regulated the expression of lipogenesis- and lipolysis-related genes in the livers of obese mice and increased AMPK phosphorylation and Sirt1 expression in the liver. Licochalcone E also attenuated hepatic inflammation and oxidative stress in obese mice. Furthermore, treatment of MCD-induced mice with licochalcone E reduced the number of lipid vacuoles and the extent of fibrosis and inhibited liver inflammation. In FL83B hepatocytes, licochalcone E could regulate lipogenesis and lipolysis, and increase the phosphorylation of AMPK and ACC. These findings provide new insights into the role of licochalcone E in regulating lipid metabolism and preventing hepatic steatosis.

Background and aims
The mechanism of cholestatic liver injury (CLI) is unclear, and effective therapies are lacking. While peroxisome proliferator-activated receptor alpha (PPARα) agonists show potential hepatoprotective effect and pyroptosis is implicated in hepatocellular damage, how PPARα activation mitigates lithocholic acid (LCA)-induced pyroptosis remains unknown.
Methods
The hepatoprotective effect of PPARα agonists was evaluated in a mouse model of intrahepatic cholestasis induced by LCA. Liver injury was assessed via serum biochemistry, hematoxylin and eosin and TUNEL staining, and electron microscopy. Pyroptosis pathways were analyzed using real-time quantitative polymerase chain reaction, Western blot, and co-immunoprecipitation.
Results
Combined morphological, histopathological, and biochemical analyses confirmed that PPARα activation protects against CLI. Compared with LCA treatment alone, PPARα activation significantly attenuated the elevation of serum lactate dehydrogenase (LDH), the increased TUNEL-positive cells, and the formation of hepatocyte membrane pores. Mechanistically, PPARα activation suppressed both NOD-like receptor protein 3 (NLRP3) inflammasome-mediated pyroptosis and apoptosis protease-activating factor-1 (APAF-1)/CASPASE-3/GSDME-mediated pyroptosis. Furthermore, PPARα agonist pretreatment inhibited activation of the nuclear factor-kappa B (NF-κB) and forkhead box O1 (FOXO1) signaling pathways.
Conclusions
PPARα protects against LCA-induced CLI by inhibiting both NLRP3 inflammasome-mediated pyroptosis associated with NF-κB and APAF-1/CASPASE-3/GSDME-mediated pyroptosis associated with the FOXO1 signaling pathway.

OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years, and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information, medication- related problems, and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included, among which females aged 20-39 years accounted for the highest proportion (66.04%); obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally, 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved, including 538 cases of drug consultations (52.28%), 453 medication recommendations (44.02%), 22 medication restructuring(2.14%), and 16 medication education (1.55%); the most common types of medication-related problems identified were adverse drug events(70.07%). CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients, challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction, enhancing pharmacist training, and establishing various forms of outpatient pharmaceutical service models.

Objective:To explore the effect of Pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) with chemotherapy on breast cancer patients who got agranulocytosis of 3 to 4 degree, agranulocytosis with fever (FN) and the influential factors of relative dose intensity (RDI) chemotherapy scheme. Meantime, the value of CD34 + and CD45 in peripheral blood on predicting agranulocytosis of 3-4 degree were investigated.Methods:A total of 104 women with breast cancer were treated at Huzhou Maternal and Child Health Hospital and Cancer Hospital of Zhejiang Province from Jan. 2022 to Sep. 2023. All subjects received primary prevention with PEG-rhG-CSF during chemotherapy. The clinical risk factors of agranulocytosis, FN and RDI were analyzed. The levels of CD34 + and CD45 in peripheral blood samples were analyzed by flow cytometry. Then the predictive value of the receiver characteristic curve (ROC) for Grade 3 to 4 agranulocytosis after primary prophylaxis with PEG-rhG-CSF for breast cancer chemotherapy was evaluated.Results:Among 104 breast cancer patients who received primary prevention of PEG-rhG-CSF during chemotherapy, 28 patients had agranulocytosis of 3 to 4 grade, 10 patients got FN, and 12 patients developed RDI<85%. The results of single factor analysis showed that CD34 +, CD45 and chemotherapy scheme were the influential factors of agranulocytosis of 3 to 4 degree, and low RDI of chemotherapy scheme ( OR=0.584, OR=0.999, OR=2.299, OR=0.100, OR=0.999, OR=3.088, P<0.05) . It also showed that CD34 + and chemotherapy scheme were the influential factors of FN ( OR=0.099, OR=2.667, P<0.05) . Multivariate Logistic regression analysis showed that CD34 +, CD45 and intensive chemotherapy were the independent risk factors of agranulocytosis of 3 to 4 degree after primary prevention with PEG-rhG-CSF ( OR=0.602, OR=0.999, OR=20.174, P<0.05) . CD34 + and intensive chemotherapy scheme were the independent influential factors of FN and RDI of chemotherapy scheme after primary prevention with PEG-RHG-CSF ( OR=0.072, OR=33.934, OR=0.086, OR=54.788, P<0.05) . The area under the curve (AUC) of CD34 + were 0.767 (95% CI:0.659-0.876) , AUC of CD45 were 0.743 (95% CI:0.644-0.842) , and the AUC of combined two indexes was 0.825 (95% CI:0.730-0.920) , which was higher than that of single index. So AUC of CD34 + and CD45 can be used for predicting agranulocytosis of grade 3 to 4 in breast cancer patients receiving primary prophylaxis with PEG-rhG-CSF. Conclusions:The levels of CD34 + and CD45 in peripheral blood of breast cancer patients with agranulocytosis of grade 3 to 4 receiving primary prevention with PEG-rhG-CSF during chemotherapy are lower. Combined detection of CD34 + and CD45 in peripheral blood can predict the occurrence of agranulocytosis of grade 3 to 4 in breast cancer patients after primary prevention with PEG-rhG-CSF. Also it can provide a reliable basis for assessing the risk of grade 3 to 4 agranulocytosis.
