Objective To investigate the activation of microglia and astrocytes, the secretion of pro-inflammatory factors, and the survival of neurons in the hippocampus of mice with acute seizures induced by pentylenetetrazol (PTZ) 24 hours after the onset of seizures. Methods Adult male C57BL/6 mice were randomly assigned to the control group and the PTZ-induced acute epileptic seizure group using random numbers, with 28 mice in each group. The activation status of microglia and astrocytes in the CA1 region of the hippocampus was evaluated by immunofluorescence 24 hours after the onset of seizures. RNA was extracted from the hippocampal tissue to detect the expression level of inflammatory factor mRNA, and HE staining was used to assess the survival of neurons in the hippocampus. Results Twenty-four hours after PTZ-induced acute seizures in mice, the numbers of activated Iba1+ microglia (55.72±4.29 vs 35.71±9.66, P<0.001) and GFAP+ astrocytes (51.61±8.21 vs 37.64±5.27, P<0.01) in the CA1 region were significantly increased compared with the control group; the proportion of M1 microglia was significantly increased (0.58±0.02 vs 0.35±0.08, P<

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

Acute ischemic stroke (AIS) is a cerebrovascular disease characterized by high morbidity, disability, and mortality, posing a significant threat to human health. Endovascular treatment has now been established as a key method for AIS management, in which stent retrievers that can mechanically remove blood clots play a key role in this technique. In recent years, stent retrievers have evolved in complexity and functionality to improve the ability of clot removing and surgical safety. However, the present instruments still have limitations on treatment efficiency, vascular adaptability, and operational precision, posing an urgent need for innovation in the design of stent retrievers. This paper systematically reviewed the structural features and working principles of AIS stent retrievers from the perspective of efficacy evaluation metrics, historical development, recent advancements in stent retrieval technology, and future prospects.

Due to the complexity of traditional Chinese medicine (TCM) interventions and the diversity of herbal components, single-omics technologies such as genomics, transcriptomics, proteomics, and metabolomics often cannot comprehensively elucidate the scientific connotations of TCM. Multi-omics technologies driven by system biology can analyze the theoretical connotations and application mechanisms of TCM from different levels such as genes, gene expression, proteins, and metabolites, in line with the holistic view of TCM, which helps to promote the modernization of TCM. By reviewing the literature on the application of omics technologies in the field of TCM, it is found that multi-omics technologies have been widely used in TCM for syndrome differentiation, evaluation of herbal quality, elucidation of pharmacological mechanisms, and drug toxicity assessment, providing comprehensive explanations of the mechanisms of action of TCM and overcoming the limitations of single-omics technologies, and having obtained significant achievements. However, multi-omics technologies also face challenges such as high cost, difficulties in data analysis due to large data volumes, and insufficient translation of research results. In the future, it is expected that through strengthening interdisciplinary cooperation, conducting long-term and dynamic clinical research, standardizing and normalizing data analysis processes, adopting appropriate and reasonable multi-omics integration patterns, establishing multi-omics databases for TCM, revealing the individualized characteristics, therapeutic mechanisms, and disease regulatory networks of TCM, the modernization of TCM will be promoted.

Background:
and Purpose CGG repeat expansion in the 5' untranslated region (5'UTR) of the Notch 2 N-terminal-like C gene (NOTCH2NLC) has been associated with neuronal intranuclear inclusion disease (NIID) and oculopharyngodistal myopathy type 3 (OPDM3). Few OPDM3 patients have been reported. This report describes two OPDM3 patients with novel imaging findings who presented the typical features of NIID, and reviews all OPDM3 cases available in the literature.
Methods:
The available clinical, imaging, and pathological information was reviewed and investigated. CGG repeat expansion in the 5'UTR of NOTCH2NLC was tested using the repeatprimed polymerase chain reaction (PCR), followed by the fluorescence amplicon-length PCR to determine the number of CGG repeats.
Results:
Our two OPDM3 patients and most patients reported in the literature developed the typical clinical characteristics of NIID, including leukoencephalopathy, peripheral neuropathy, cognitive deterioration, pigmentary retinopathy, ataxia, tremor, acute encephalitis-like episodes, pigmentary retinopathy, miosis, and sensorineural hearing loss. In addition to typical imaging findings of NIID, our two patients exhibited diffusion weighted imaging (DWI) hyperintensities in the middle cerebellar peduncles, which have not been described previously. Muscle biopsies revealed rimmed vacuoles and p62-positive intranuclear inclusions in the myofibers in both patients. The skin biopsy performed in one patient detected typical eosinophilic intranuclear inclusions. Genetic analysis identified CGG repeat expansion in NOTCH2NLC as the causative mutation in the two patients.
Conclusions
Our two patients with OPDM3 had clinical characteristics of NIID and exhibited DWI abnormality in the cerebellum. Our results indicate that OPDM3 is within the spectrum of NIID and that DWI hyperintensities in the cerebellum are helpful for diagnosing NIID or OPDM3.

We here investigated the effect of MS4A6D(the membrane spanning 4-domain subfamily A(MS4A)superfamily protein 6D),one of the tetraspanins which specifically expresses on the membrane of macrophages,on carrageenan(CGN)-induced mouse foot pad swelling and its possible mechanism.Male C57BL/6 wild-type(WT)and various gene knockout(including Ms4a6d-/-,Nlrp3-/-,Casp-1-/-and IlR1-/-)mice were recruited and injected with 100 μl 1%CGN(w/v)and 20 μl CaCl2(50 mmol/L)to establish the foot pad swelling model,and then the severity of foot pad swelling in WT and gene knockout mice were compared.H&E staining was performed to investigate the pathological changes,and immunofluorescence was used to detect the infiltration of F4/80+ macrophages in the foot pad tissue.Finally,Western blot was used to determine the protein expression of NLRP3,IL-1 β,TNF-α and IL-6.Data showed that the combined injection of 100 μl 1%CGN(w/v)and 20 μl CaCl2(50 mmol/L)significantly promoted the swelling of foot pads,while the degree of foot pad swelling in Ms4a6d-/-mice was significantly lower than that in WT littermates(P<0.05);Significant tissue damage and inflammatory infiltration as well as necrotic lesions were observed in the WT foot pads,whereas,the degrees from Ms4a6d-/-foot pads showed significantly reduced;The protein levels of Caspase-1 and IL-1β in the foot pad tissue of the WT model were significantly higher than those of the Ms4a6d-/-groups;Compared with WT controls,the degree of foot pad swelling in Nlrp3-/-,Casp-1-/-,and IlR1-/-mice induced by 1%CGN(w/v)and CaCl2(50 mmol/L)were also significantly reduced(P<0.05).Taken together,MS4A6D promotes the activation of NLRP3 inflammasome in macrophages and induces IL-1β secretion,by thus deteriorates CGN-mediated swelling of mouse foot pads.
