1.Research advances in the involvement of inflammatory response in cardioembolic stroke
Journal of Apoplexy and Nervous Diseases 2025;42(8):762-768
Cardioembolic stroke is a special type of ischemic stroke caused by cardiac diseases, and its development is closely associated with the structural and functional abnormalities of the heart. The pathophysiological mechanisms of this type of stroke are complex. It is often induced by thrombosis due to cardiac diseases, followed by thrombus detachment and entry into cerebral vessels, leading to ischemic injury and subsequent cascade reactions. Inflammatory response plays a crucial role in the development and progression of cardioembolic stroke, being involved in processes ranging from thrombosis to acute-phase brain injury after embolism, short-term neurological recovery, and long-term prognosis prediction, and can also be used as a biomarker and diagnostic factor. This article summarizes the mechanism by which inflammation contributes to the development and progression of cardioembolic stroke, as well as the current research advances in the etiology of cardioembolic stroke, the recovery of neurological function after stroke, and personalized treatment strategies.

Objective:To explore the clinical manifestations and genetic basis for a Chinese pedigree affected with atypical Charcot-Marie-Tooth disease type 1 A (CMT1A).Methods:A patient admitted to the Department of Neurology, Xijing Hospital Affiliated to Air Force Medical University in June 2022 was selected as the study subject. Clinical data of the patient was collected, and 17 family members from four generations of this pedigree were traced based on pes arcuatus and atypical clinical symptoms. Neuroultrasound and genetic testing were carried out on available family members. Whole exome sequencing and multiple ligation-dependent probe amplification assay were carried out for the proband and some of the affected members of the pedigree.Results:The proband, a 15-year-old male, had presented with paroxystic limb pain with weakness, accompanied by pes cavus and hypertrophy of gastrocnemius muscles, without stork leg sign caused by muscles atrophy in the distal lower extremities. MRI has revealed no sign of fat infiltration in the muscles of both legs. Nerve conduction examination had indicated damages of the sensory and motor nerves of the limbs, mainly with demyelinating changes. Seven members of the pedigree had pes arcuatus, including 5 presenting with paroxysmal neuropathic pain and myasthenia in the limbs, whilst 2 were without any clinical symptoms. Neurosonography of the proband, his brother, father and aunt showed thickened peripheral nerves of the extremities with unclear bundle structure. Genetic analysis revealed a large repeat encompassing exons 1 to 5 of the PMP22 gene and flanking regions (chr17: 15133768_15502298) in some of the affected members, which was predicted to be pathogenic. Conclusion:The duplication of PMP22 gene was considered to be pathogenic for this CMT1A pedigree.

To evaluate the therapeutic effect and mechanism of rapamycin (RAPA) on pulmonary fibrosis induced by chlormethine in C57BL/6N mice. Based on body weight, the 18-20 g C57BL/6N mice were randomly divided into five groups: control group, chlormethine group, chlormethine+dexamethasone (1 mg/kg) group, chlormethine+RAPA (1 mg/kg) group and chlormethine+RAPA (2 mg/kg) group, with ten mice in each group. Mice were put to death on the 21st day after the first administration of chlormethine. HE staining and Masson staining were used to observe the pathological changes and degree of fibrosis in the lung tissue of mice, and RT-PCR was used to detect collagen Ⅰ, E-cadherin, vimentin, and α-SMA mRNA expression. After 21 days of administration of chlormethine to mice, significant pulmonary fibrosis characteristics were observed in the lung tissue of the mice. Compared with the chlormethine group, the weight of mice in the chlormethine+dexamethasone (1 mg/kg) group, chlormethine+RAPA (1 mg/kg) group and chlormethine+RAPA (2 mg/kg) group, significantly increased ( P<0.05). Compared with the chlormethine group, the expression of pulmonary fibrosis-related indicators (collagen Ⅰ, E-cadherin, vimentin, and α-SMA) significantly improved ( P<0.05) in the chlormethine+dexamethasone (1 mg/kg) group, chlormethine+RAPA (1 mg/kg) group and chlormethine+RAPA (2 mg/kg) group. Compared with the chlormethine group, the pathological changes and collagen deposition in the lung tissue of mice in the chlormethine+dexamethasone (1 mg/kg) group, chlormethine+RAPA (1 mg/kg) group and chlormethine+RAPA (2 mg/kg) group, were significantly improved. Transcriptome analysis of the lung tissue of mice revealed that RAPA treatment of chlormethine-induced pulmonary fibrosis might be related to NF-kappa B signaling pathway. Compared with the chlormethine group, the mRNA expression of p65 in the lung tissue of mice in the chlormethine+dexamethasone (1 mg/kg) group, chlormethine+RAPA (1 mg/kg) group and chlormethine+RAPA (2 mg/kg) group, significantly decreased ( P<0.01). RAPA has a protective effect on pulmonary fibrosis induced by chlormethine in mice. Its efficacy is comparable to that of dexamethasone, which is currently being used in clinical practice. It is a new alternative therapy, and its mechanism may be related to inhibiting the activation of the NF-kappa B signaling pathway.

This study aims to observe the effect of Panax notoginseng extracts on inflammatory re-sponse in immunosuppressed broilers and to investigate the mechanism through network pharma-cology and molecular docking combined with in vivo animal tests.Based on the TCMSP database and GeneCard and other disease databases,we searched for targets related to Panax notoginseng and broiler inflammation,screened key compounds and targets by applying Cytoscape 3.7.1 and String databases,respectively,and constructed a network relationship diagram of traditional Chi-nese medicine(TCM)-key components-targets,and carried out GO functional enrichment and KEGG pathway enrichment analyses by using the DAVID platform.The GO functional enrichment analysis and KEGG pathway enrichment analysis were carried out by the DAVID platform,visual-ized by the Chiplot online website,and finally,the core clustered proteins were analyzed by Pymol software to obtain the core targets,and molecular docking technology was used to predict the de-gree of matching between the active ingredients and the core targets as well as the animal experi-ments to further explore the pharmacological mechanism of Panax notoginseng extracts.Sixty 1-day-old red-feathered broilers were randomly divided into three groups(LPS group,CON group,and PN group),and the test period was 35 days.The LPS and PN groups were injected intraperito-neally with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline on the 12,14,33,and 35 d.The LPS and PN groups were injected with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline.The effect of Panax notoginseng extract on inflammatory cytokines in serum was detected by ELISA,and the hormone content in serum was also detected in each group,and fluorescence quantitative PCR was used to detect the effect of each group on the mRNA ex-pression levels of STAT3,IL-6,and CASP3.The results showed that the serum levels of IFN-γ,IL-6,iNOS,TNF-α,and TNF-β were significantly increased(P<0.05),while the level of IL-10 was significantly decreased(P<0.05)after LPS tapping at weeks 2 and 5.The serum levels of IFN-y,IL-6,iNOS,TNF-α,and TNF-β were significantly decreased(P<0.05)and IL-10 was sig-nificantly increased(P<0.05)by the addition of Panax ginseng extracts to the basal diet com-pared with the LPS group.Panax notoginseng extracts significantly decreased the serum levels of adrenocorticotropic hormone(ACTH)and corticosterone(CORT)(P<0.05)and increased the levels of growth hormone(GH)(P<0.05).A total of 8 active ingredients and 123 potential tar-gets for broiler inflammation were predicted by network pharmacology.The protective mechanism of Panax notoginseng against broiler inflammation may be related to the C-type lectin receptor(CLR)signaling pathway,Toll-like receptor(TLR)signaling pathway,MAPK signaling pathway,NOD-like receptor(NLR)signaling pathway,and FoxO signaling pathway.According to the pre-diction,the alleviation of inflammatory response in broiler chickens by Panax notoginseng may be related to the action on 12 key targets.Fluorescence quantitative PCR showed that Panax notogin-seng extract down-regulated the mRNA expression of IL-6 and CASP3(P<0.05)and up-regula-ted that of STAT3(P<0.05),and molecular docking results also showed that the active ingredi-ents in Panax notoginseng extracts could exert anti-inflammatory effects through IL-6 and CASP3.The results suggested that Panax quinquefolium extracts might alleviate the inflammatory response of immune-stressed broilers through multi-components,multi-targets,and multi-path-ways,and this study helps propose new therapeutic strategies and provides a theoretical basis for the development of feed additives based on Penthorum chinense Pursh extract.
