Objective:To observe the effects of Traditional Chinese Medicine (TCM)ultrasound drug permeation electrotherapy device on the inflammatory response of rats with cerebral ischemia, and to provide an experimental basis for the clinical application of TCM ultrasound drug permeation electrotherapy device in the treatment of cerebral ischemia.Methods:A total of 72 SD rats were randomly divided into sham-operation group (12 rats) and modeling group (60 rats). The middle cerebral artery occlusion (MCAO) model was prepared by thread embolism in the model group. The rats were divided into model group, Chinese medicine tablet group, blank tablet + TCM ultrasound drug permeation electrotherapy group (hereinafter referred to as "blank tablet + electrotherapy group"), Chinese medicine tablet + TCM ultrasound drug permeation electrotherapy group (hereinafter referred to as "Chinese medicine tablet + electrotherapy group") and butylphthalide group according to the random number table method, with 12 rats in each group. The corresponding treatment was given continuously for 7 days. The neurological function was scored using Longa method evaluation criteria; TTC staining was used to observe the infarct volume and calculate the percentage of infarct volume; HE staining was used to observe the cell morphology of cortical area in each group of rats; ELISA was used to detect the serum TNF-α and IL-1β levels in each group of rats; TLR4, MyD88 and NF-κBp65 protein expressions in hippocampal tissue of each group of rats on the infarct side were detected by Western blot method.Results:Compared with the model group, the neurological function scores of rats in the blank tablet + electrotherapy group, the herbal tablet + electrotherapy group, and the butylphthalein group significantly decreased ( P<0.05), the percentage of cerebral infarct volume significantly decreased ( P<0.05), the contents of serum TNF-α and IL-1β significantly decreased ( P<0.05), and the expressions of TLR4 (0.42±0.07, 0.31±0.07, 0.19±0.04 vs. 0.68±0.14), MyD88 (0.39±0.12, 0.30±0.07, 0.23±0.11 vs. 0.67±0.10), NF-κBp65 (0.32±0.03, 0.27±0.02, 0.17±0.03 vs. 0.57±0.12) protein in hippocampal tissue significantly decreased ( P<0.05). Conclusion:The TCM ultrasound drug permeation electrotherapy device can inhibit TLR4, MyD88, NF-κBp65 protein expressions and reduce the release of serum inflammatory factors TNF-α and IL-1β, thus exerting cerebral ischemic protective effects.

ObjectiveTo investigate the mechanism of Xumingtang in Gu Jin Lu Yan （《古今录验》） in regulating cell pyroptosis through the hypoxia-inducible factor-1α （HIF-1α）/NOD-like receptor pyrin domain-containing protein 3 （NLRP3） pathway in ischemic stroke （IS）. MethodSD rats were randomly divided into a sham operation group， a model group， low- and high-dose Xumingtang groups， and a metformin group， with 20 rats in each group. Oral administration was performed for 3 days， and tissue samples were collected. Differential messenger RNA （mRNA） was screened using high-throughput sequencing， and Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analyses were performed on key differentially expressed genes. The modified neurological severity score （mNSS） and 2，3，5-triphenyltetrazolium chloride （TTC） staining were used to evaluate the effect of brain infarction. Hematoxylin-eosin （HE） staining was used for pathological morphological observation of brain tissue. Enzyme-linked immunosorbent assay （ELISA） was used to compare the levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） in the ischemic cortical region. Double staining immunohistochemistry was used to detect the co-localization of HIF-1α and NLRP3. Real-time quantitative polymerase chain reaction （PCR） was performed to detect the mRNA expression of NLRP3， HIF-1α， Caspase-1 （CASP-1）， and gasdermin D （GSDMD）. Western blot was used to detect the protein expression of HIF-1α， NLRP3， CASP-1， and GSDMD. ResultA total of 5 705 differentially expressed genes （2 733 downregulated and 2 972 upregulated） were obtained by mRNA sequencing. After conversion to homologous genes and intersection with the pyroptosis gene set， 95 key differentially expressed pyroptosis genes were obtained. Compared with the sham operation group， the model group showed significantly increased mNSS scores， larger brain infarction areas （P<0.01）， diverse neuronal morphology， disordered arrangement， widened cell gaps， significantly increased levels of IL-1β and IL-18 in the ischemic cortical region （P<0.01）， enhanced co-localization fluorescence intensity， and significantly increased mRNA and protein expression levels of HIF-1α， NLRP3， CASP-1， and GSDMD （P<0.01）. Compared with the model group， the high-dose Xumingtang group showed the most significant improvement in neurological function scores and brain infarction areas （P<0.01）. The neuronal integrity and arrangement were more complete， and the cell gaps were narrower in all groups with drug treatment， with significantly reduced co-localization fluorescence intensity. Xumingtang could reduce the levels of IL-1β， IL-18， and the mRNA and protein expression of HIF-1α， NLRP3， CASP-1， and GSDMD （P<0.05， P<0.01）， with the high-dose Xumingtang group showing the most significant effect （P<0.01）. ConclusionXumingtang in Gu Jin Lu Yan can inhibit cell pyroptosis and promote neurological function recovery after IS， which may be related to the inhibition of the HIF-1α/NLRP3 pathway.
