Post-stroke epilepsy （PSE） is one of the most common complications of stroke and represents a leading cause of secondary epilepsy in adults. Its development follows a well-defined temporal sequence， progressing through stroke onset， latent phase remodeling， and eventual seizure manifestation. PSE is classified into early- and late-onset types based on the timing of seizures. The former is associated with acute injury， while the latter involves chronic reorganization of neural networks. During the latent phase， the brain exhibits pathological changes such as disrupted synaptic plasticity， inflammatory activation， oxidative stress accumulation， and blood-brain barrier disruption， offering a critical window for therapeutic intervention. However， conventional antiseizure medications， which primarily inhibit abnormal neuronal discharges， are insufficient to reverse the underlying pathogenesis and show limited preventive efficacy. Against this backdrop， the concept of disease-modifying treatment （DMT） has gained traction. DMT underscores mechanistic， targeted， and early-stage interventions that prioritize core processes such as inflammation， synaptic remodeling， ferroptosis， and miRNA regulation. Due to its predictability and ease of modeling， PSE serves as an ideal platform for DMT research. Emerging strategies encompass small-molecule drugs， stem cell transplantation， epigenetic modulation， and neuromodulation， some of which have shown promising results in animal models. This review systematically summarizes the pathogenesis of PSE and recent advances in DMT approaches， providing a theoretical foundation and practical guidance for clinical interventions.

MethodsThe rat's trigeminal neuralgia model was constructed by infraorbital injection of Talci Pulvis， and the rats were randomly divided into the normal group， model group， carbamazepine group （60 mg·kg^-1）， Cranial Painkiller granules group （2.70 g·kg^-1）， and low， medium， and high dosage groups of Cranial Painkiller pills' extract powder （1.35， 2.70， 5.40 g·kg^-1） according to the basal mechanical pain thresholds， and there were 10 rats in each group. The drug was administered by gavage to each group 2 h after modeling， and distilled water was given by gavage to the normal and model groups under the same conditions once a day for 10 d. Von Frey brushes were used to measure mechanical pain thresholds in rats. Hematoxylin-eosin （HE） staining was used to detect pathological changes in the trigeminal ganglion， and enzyme-linked immunosorbent assay （ELISA） was used to detect the inflammatory factors interleukin-1 （IL-1）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， and tumor necrosis factor-α （TNF-α） levels in rat serum， as well as neuropeptide substance P （SP） and β-endorphin （β-EP） levels in rat brain tissue. Western blot technique was used to detect the levels of NLRP3， ASC， Caspase-1， and OTULIN proteins in rat brain tissue. ResultsCompared with the normal group， the pain threshold of rats in the model group showed a continuous significant decrease （P<0.01）. The pathological damage of brain tissue was significant （P<0.01）， and the inflammatory levels of IL-1， IL-6， IL-8， and TNF-α in serum were significantly elevated （P<0.01）.

After administration of the drug， compared with the model group， the pain threshold of each dose group of the Cranial Painkiller pills' extract powder and the Cranial Painkiller granules group significantly increased （P<0.01）. The inflammatory levels of IL-1， IL-6， IL-8， and TNF-α and SP levels significantly decreased （P<0.01）， and the β-EP levels were significantly elevated （P<0.01）， while the levels of OTULIN protein were significantly elevated （P<0.05， P<0.01）， and the levels of NLRP3， ASC proteins were decreased （P<0.01）in high dose Cranial Painkiller pills' extract powder. Meanwhile， compared with those in the model group， the trigeminal ganglion lesions of rats in the Cranial Painkiller pills' extract powder and Cranial Painkiller granules groups showed different degrees of improvement （P<0.05， P<0.01）. ConclusionThe Cranial Painkiller pills' extract powder has significant therapeutic effects on the rat model of trigeminal neuralgia induced by infraorbital injection of Talci Pulvis， and its mechanism is related to the improvement of OTULIN-regulated neuroinflammation.

ObjectiveThis paper aims to investigate the therapeutic effects of Jidesheng Sheyao tablets on varicella-zoster virus （VZV） and its associated postherpetic neuralgia （PHN） to provide experimental evidence for the clinical application and secondary development of Jidesheng Sheyao tablets. MethodsFifty-six guinea pigs were randomly divided into seven groups according to their body weight， namely the normal group， the model group， the positive control group， the high-dose group， medium-dose group， and low-dose group of Jidesheng Sheyao tablets （1.92， 0.96， 0.48 g·d^-1）， and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets （0.96 g·d^-1 + 1.2 g·kg^-1·d^-1）. The skin on the back of the guinea pigs in each group was depilated and then abraded with sandpaper. Except for the normal group， 200 μL of VZV solution was dropped on the damaged parts of the back of the guinea pigs in the other groups， and the infection lasted for 2 consecutive days. The drug administration started 2 hours after the infection on the first day and lasted for 7 days. The pathological changes of the back of the guinea pigs in each group were observed every day starting from the second day after the infection. On the 7^th day， the guinea pigs were sacrificed by CO₂ anesthesia. The locally infected skin was taken， and the viral DNA nucleic acid load was detected by real-time polymerase chain reaction （Real-time PCR）. The pathological histology examination was carried out after hematoxylin-eosin （HE） staining. Seventy rats were randomly divided into seven groups according to their body weight， namely the normal group， the model group， the positive control group， the high-dose group， medium-dose group， and low-dose group of Jidesheng Sheyao tablets （1.08， 0.54， 0.27 g·d^-1）， and the group treated with oral administration combined with topical application of Jidesheng Sheyao tablets （0.54 g·d^-1 + 1.2 g·kg^-1·d^-1）.

ObjectiveTo explore the effects of the Tibetan medicine Sanwei Doukoutang （SWDK） on cognitive dysfunction in mice suffering from Alzheimer's disease （AD） and its related mechanism. MethodsFifty SPF 5 × FAD mice were randomly divided into model group， total ginsenoside group（0.04 g·kg^-1）， high-， medium-， and low-dose groups of SWDK （32.60， 16.30， 8.15 g·kg^-1）， with 10 mice in each group， and ten wild-type mice of the same age were used as the normal group， male and female in 1∶1. Gavage administration was performed once daily for 8 weeks. The Morris water maze test and contextual fear memory experiment were used to observe learning and memory function. Hematoxylin-eosin （HE） staining was utilized to observe the changes in the pathomorphology of brain tissue in mice. The levels of synaptophysin （SYP） and postsynaptic dense substance 95 （PSD95） in mice serum were detected by enzyme-linked immunosorbent assay （ELISA）. The positive expression of brain-derived neurotrophic factor（BDNF） in the dentate gyrus （DG） region of mouse brain tissue was observed by immunohistochemistry （IHC）. The protein levels of BDNF， Wnt family member 3A（Wnt3a）， and β-catenin were detected in the hippocampus of mice by Western blot. ResultsCompared with the normal group of mice， the model group of mice had significantly more complex swimming routes and lower swimming speed （P<0.01）， significantly lower percentage of time spent in the target quadrant （P<0.01）， and a significantly lower percentage of freezing time （P<0.05）. The number of neurons in the hippocampal region of mice was obviously reduced and unevenly arranged. The levels of SYP and PSD95（P<0.01） in the serum of mice were reduced， and the positive expression of BDNF in the DG region of the brain tissue of mice was reduced. The levels of hippocampal BDNF， Wnt3a， and β-catenin proteins in the hippocampus of mice were obviously reduced （P<0.05， P<0.01）. Compared with the model group， the mice in the SWDK group and the total ginsenoside group had significantly shorter swimming routes， the high- and medium- dose SWDK groups significantly higher swimming speeds （P<0.01）， significantly higher percentage of time spent in the target quadrant （P<0.01）， obviously higher percentage of Freezing time （P<0.05）， and obviously more neurons in the hippocampal region of the mice with tighter arrangement. The mice had elevated levels of serum SYP （P<0.05， P<0.01）， PSD95 （P<0.01）， increased BDNF-positive cells in the DG region of brain tissue， and obviously elevated levels of BDNF， Wnt3a， and β-catenin proteins in the hippocampus of mice （P<0.05， P<0.01）. ConclusionSWDK can significantly improve the cognitive dysfunction of AD mice， and its mechanism may be related to regulating the Wnt/β-catenin signaling pathway， which promotes BDNF expression and thereby enhances synaptic plasticity， allowing neuronal signaling to be restored.

Objective To establish a dynamic model of lipopolysaccharide-induced acute lung injury in mice based on the NLRP3/Caspase-1/gasdermin D(GSDMD)pyroptosis pathway,and observe the result ing lung injury at different time points.We aimed to identify the optimal time for modelling according to the injury at different time points and the expression of pyroptosis pathway-related proteins,to lay the foundation for animal models for subsequent experiments.Methods Fifty-four 6～8 weeks old male SPF BALB/c mice were divided randomly into nine groups,including Con group and model groups at 1,3,6,12,18,24,48,and 72 h.Body weight and lung tissue were detected by general and pathological observations and semi-quantitative scoring,including lung index,lung water content,and wet and dry weight ratio.The white blood cell count and concentrations of tumor necrosis factor-α,interleukin(IL)-6,IL-1β,IL-18,and BCA protein were detected in bronchoalveolar lavage fluid(BALF).The classic pyroptosis pathway-related proteins NLRP3,pro-Caspase 1,Caspase 1,and GSDMD were detected by Western Blot.Results Body weight decreased in all experimental groups,with the most significant weight loss in the 24 and 48 h groups.Gross observation and pathological examination of lung tissue showed that the most severe lung injury occurred at 24～72 h,with significant differences between each group and the control group.The lung index,lung water content,and wet/dry weight ratio were also significantly increased at 24～72 h.White blood cells in BALF started to increase from 6 h after model initiation,48 h can reach a peak,72 h all keep increasing.IL-18 in BALF began to increase at 24 h and continued to increase at 72 h.The inflammatory factors tumor necrosis factor-α,IL-1β,IL-6 were highest at 6 h and significantly reduced at 48 h.Protein concentrations in BALF were significantly increased within 24,48,and 72 h compared with those in the control group.The pyroptosis pathway proteins NLRP3,pro-Caspase-1,Caspase-1,and GSDMD were significantly enhanced in each time series,and channel protein expression was significantly enhanced at 24～72 h compared with that in the Con group.Conclusions Comprehensive analysis of experimental indicators,inflammatory factors,and pathway proteins at different times showed that the mechanism of pyroptosis was closely related to the occurrence and progression of acute lung injury.Expression of the pyroptosis pathway was most obvious and lung injury was most serious at 24～48 h.This study provides a model reference and experimental basis for subsequent studies of the specific mechanism and intervention targets of acute lung injury.

In this study,freeze-drying methods was used to prepare astragalus polysaccharide synbi-otic powder.The optimized freeze-dried protective agent formulation using response surface meth-odology in this study was 17.99％skimmed milk powder,7.26％sucrose,8.04％galactooligosac-charides,and 9.64％astragalus polysaccharide,and the remaining amount was distilled water.The survival rate of lactic acid bacteria in the prepared bacterial powder was 88.06％.A calf feeding ex-periment was conducted over 28 days with thirty healthy newborn calves with similar age,the calves were randomly assigned to either control group and the astragalus polysaccharide synbiotic group,each comprising 15 calves.The astragalus polysaccharide synbiotic group received a supple-ment of astragalus polysaccharide in addition to their regular feed.Compared to the control group,the results showed that:(1)Astragalus polysaccharide synbiotics significantly increased the aver-age daily gain(ADG)of calves and decreased the fecal score and diarrhea rate in calves.(2)By tes-ting the immunological indexes,we found that astragalus polysaccharide synbiotics significantly in-creased the serum level of IgA,IgG,IgM,IL-2 and IL-10,and decreased the level of IL-6 and TNF-α.(3)Astragalus polysaccharide synbiotics notably enhanced the Chao1,Sobs,and Shannon indi-ces,while reducing the Simpson index.At the phylum level,astragalus polysaccharide synbiotics group showed a significant increase in the relative abundance of Cyanobacterium and Firmicutes,and a decrease in Proteobacteria.At the genus level,the relative abundance of Esche-richia-Shigella in astragalus polysaccharide synbiotic group significantly decreased.Whereas norank_f__norank_o__Clostridia_UCG-014 and Butyricicoccus significantly increased.In conclu-sion,this study successfully formulated an astragalus polysaccharide synbiotic powder.The powder can significantly promote the growth of calves,enhance immune function,improve the structure of gut microbiota,and reduce the incidence of calf diarrhea.

Objective To investigate the predictive value of combined plasma gluconic acid(GA),fumaric acid(FA),and pseudouridine levels at admission for acute kidney injury(AKI)in elderly patients with acute myocardial infarction(AMI).Methods A total of 78 elderly AMI patients transferred from Emergency Department to Coronary Care Unit in Fuwai Hospital during Decem-ber 2021 and July 2022 were enrolled in this prospective study.They were divided into AKI group(40 cases)and non-AKI group(38 cases)according to whether they developed AKI during hospi-talization.Plasma levels of GA,FA and pseudouridine were quantitatively detected with liquid chromatography-tandem mass spectrometry.ROC curve was plotted to assess the predictive value of these three plasma metabolites for AKI in AMI patients.Multivariate logistic regression analy-sis was applied to analyze the clinical risk factors for AKI.Results There were no statistical differences in the plasma levels of GA,FA and pseudouridine between the AKI group and the non-AKI group(P＞0.05).ROC curve analysis revealed that the plasma levels of the three indicators had no predictive value for the development of AKI in elderly AMI patients(AUC=0.576,95％CI:0.449-0.704,P=0.246;AUC=0.595,95％CI:0.467--0.721,P=0.154;AUC=0.563,95％CI:0.435-0.692,P=0.337).Multivariate logistic regression analysis revealed that left ventricu-lar ejection fraction(LVEF)was an independent predictor for AKI development in elderly AMI patients(OR=0.923,95％CI:0.870-0.978,P=0.007).Conclusion Plasma GA,FA and pseud-ouridine cannot predict the development of AKI in elderly AMI patients,while,LVEF is an inde-pendent predictor for the development.
