ObjectiveTo investigate the material basis of the pathogenesis of cerebral ischemic injury with blood stasis and toxin syndrome and to explore the protective effects of Huayu Jiedu prescription （HYJDP） on neutrophil extracellular trap-related cell death （NETosis） in cerebral ischemic injury following acute cerebral infarction. MethodsSeventy-two Sprague-Dawley （SD） rats were randomly divided into six groups （n=12 per group）： sham operation （Sham） group， blood stasis and toxin model （Model） group， low-， medium-， and high-dose HYJDP groups （HYJDP-L， HYJDP-M， and HYJDP-H； 9， 18， and 36 g·kg^-1， respectively）， and butylphthalide （NBP） group （0.06 g·kg^-1）. Except for the Sham group， rats in all other groups were subjected to carrageenan/dry yeast combined with a modified intraluminal filament method to establish a focal cerebral ischemia model of the middle cerebral artery with blood stasis and toxin syndrome. Neurological function was evaluated at 24 h after modeling using the Zea-Longa neurological deficit score. Cerebral infarction rate was assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining. Pathological morphology of brain tissue was observed using hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was used to determine serum levels of interleukin-8 （IL-8）， myeloperoxidase-DNA complexes （MPO-DNA）， and citrullinated histone H3 （CitH3）. Protein expression of phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， protein kinase B （p-Akt）， mammalian target of rapamycin （p-mTOR）， sequestosome 1 （p62）， and CitH3 in brain tissue was detected by Western blot. Immunofluorescence （IF） was used to detect the expression of neutrophil-specific marker Ly6G， CitH3， and neuron-specific nuclear protein （NeuN） in brain tissue. ResultsCompared with the Sham group， neurological deficit scores and cerebral infarction rates in the model group were significantly increased （P<0.01 for both）. HE staining showed varying degrees of neuronal degeneration and necrosis， characterized by blurred neuronal structures， nuclear pyknosis and fragmentation， cytoplasmic dissolution into a vacuolated reticular pattern， and mild glial cell proliferation. ELISA results showed that serum levels of IL-8， MPO-DNA， and CitH3 were significantly increased （P<0.01）. Western blot analysis demonstrated decreased expression of p-PI3K， p-Akt， p-mTOR， and p62， while CitH3 expression was significantly increased （P<0.01）. IF results showed an increased number of NETs⁺ cells and a significant decrease in NeuN⁺ cells （P<0.01）. Compared with the Model group， neurological deficit scores in the HYJDP-H group were significantly decreased （P<0.05）， and cerebral infarction rates in the HYJDP-H and NBP groups were significantly reduced （P<0.01）. HE staining showed that brain tissue damage was markedly alleviated in the HYJDP-H group. ELISA results showed that levels of IL-8， MPO-DNA， and CitH3 were significantly decreased in the HYJDP-M， HYJDP-H， and NBP groups （P<0.01）. Western blot analysis showed that expression of p-PI3K， p-Akt， p-mTOR， and p62 was significantly increased in the HYJDP-H and NBP groups， while CitH3 expression was significantly reduced in all drug intervention groups （P<0.01）. IF results showed that the number of NETs⁺ cells was significantly decreased and the number of NeuN⁺ cells was significantly increased in all drug intervention groups （P<0.01）. ConclusionNETs may be the material basis of the pathogenesis of cerebral ischemic injury characterized by blood stasis and toxin. HYJDP can regulate the PI3K/Akt/mTOR signaling pathway， reduce the release of pro-inflammatory mediators and NETosis-related products， alleviate cerebral ischemic injury caused by autophagy-dependent NETosis， and thereby exert a neuroprotective effect.

ObjectiveTo investigate the effects of Huayu Jiedu prescription on brain microvascular endothelial cells （BMECs） after oxygen-glucose deprivation （OGD） injury and to explore its intervention mechanisms. MethodsThe cell counting kit-8 （CCK-8） assay was used to determine the optimal OGD duration and the effective concentration of Huayu Jiedu prescription-containing serum. Cells were randomly divided into the blank serum medium group （KBXQ）， model group （OGD）， HYXQ group （OGD + Huayu Jiedu prescription-containing serum）， and 3-methyladenine （3-MA） group （OGD + 3-MA）. Cell morphology was observed under an inverted microscope. The numbers of autophagosomes and autolysosomes in cells were observed by transmission electron microscopy. Cell viability was determined using the CCK-8 assay. Cell apoptosis rate was detected using the TdT-mediated dUTP nick-end labeling （TUNEL） assay. The expression levels of microtubule-associated protein 1 light chain 3 （LC3） and Occludin were detected by immunofluorescence. The permeability of the cell monolayer was also measured. Cells were further randomly divided into the KBXQ group， model group （OGD）， HYXQ group， phosphatidylinositol-3 kinase （PI3K） inhibitor （LY294002） group （OGD + LY294002）， and HYXQ + LY294002 group （OGD + Huayu Jiedu prescription-containing serum + LY294002）. Western blot analysis was used to detect the expression levels of the autophagy-related key molecule yeast Atg6 homolog 1 （Beclin1）， LC3Ⅱ/LC3Ⅰ， selective autophagy adaptor protein （p62）， Occludin， phosphorylated （p）-PI3K， PI3K， phosphorylated protein kinase B （p-Akt）， Akt， phosphorylated mammalian target of rapamycin （p-mTOR）， and mTOR. ResultsOGD for 6 h was selected as the optimal modeling condition， and 5% was determined as the optimal volume fraction of Huayu Jiedu prescription-containing serum. Compared with the KBXQ group， the model group showed obvious cell damage under the inverted microscope， and transmission electron microscopy revealed markedly increased numbers of autophagosomes and autolysosomes. Cell viability was significantly decreased （P<0.01）， apoptosis rate was significantly increased （P<0.01）， LC3 fluorescence intensity was significantly increased （P<0.01）， Occludin fluorescence intensity was significantly decreased （P<0.01）， and monolayer permeability was significantly increased （P<0.01）. Compared with the model group， cell damage in the HYXQ group and the 3-MA group was significantly improved， the numbers of autophagosomes and autolysosomes were markedly reduced， cell viability was significantly increased （P<0.01）， apoptosis rate was significantly decreased （P<0.01）， LC3 fluorescence intensity was significantly decreased （P<0.01）， Occludin fluorescence intensity was significantly increased （P<0.01）， and monolayer permeability was reduced （P<0.05）. Western blot results showed that， compared with the KBXQ group， the model group exhibited significantly increased expression of Beclin1 and LC3Ⅱ/LC3Ⅰ （P<0.01）， while the expression levels of p62， Occludin， p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR were significantly decreased （P<0.01）. Compared with the model group， the HYXQ group showed significantly decreased expression of Beclin1 and LC3Ⅱ/LC3Ⅰ （P<0.01） and significantly increased expression of p62， Occludin， p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR （P<0.01）. In the LY294002 group， Beclin1 and LC3Ⅱ/LC3Ⅰ expression were significantly increased （P<0.05， P<0.01）， whereas the expression levels of p62， Occludin， p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR were significantly decreased （P<0.01）. Compared with the LY294002 group， the HYXQ + LY294002 group showed significantly decreased expression of Beclin1 and LC3Ⅱ/LC3Ⅰ （P<0.01） and significantly increased expression of p62， Occludin， p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR （P<0.01）. ConclusionHuayu Jiedu prescription has a protective effect on BMECs after OGD injury， which may be achieved by activating the PI3K/Akt/mTOR autophagy-related signaling pathway and inhibiting excessive autophagy， thereby protecting Occludin protein expression and endothelial barrier function.

ObjectiveTo explore the regulation of hypothalamic-pituitary-gonadal （HPG） axis by modified Erxian decoction in rats with perimenopausal syndrome （PMS） and to further analyze the expression of proteins related to the silent information regulator 1 （SIRT1）/hypothalamic kisspeptin （Kisspeptin）/gonadotropin-releasing hormone （GnRH） signaling pathway in the arcuate nucleus region （ARC） of the hypothalamus， so as to reveal the potential target of action and molecular biological mechanism of modified Erxian decoction for the treatment of perimenopausal syndrome. MethodsAn animal model was established via the incomplete castration method， with successful modeling confirmed by the exfoliated cervical cell smear method. The 48 rats were divided into six groups based on the randomization principle after successful modeling， including a sham operation group， a model group， an estradiol valerate group （0.09 mg∙kg^-1∙d^-1）， high-， medium-， and low-dose modified Erxian decoction groups （7.614， 3.807，1.903 5 g∙kg^-1∙d^-1）， with 8 rats in each group. The estradiol valerate group and the high-， medium- and low-dose modified Erxian decoction groups were continuously administered by gavage for 28 days， and the indicators were detected 24 hours after the last administration. Body weights and uterine indices were measured. The pathological changes of the uterus were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay （ELISA） was performed to measure the levels of estradiol （E₂）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and gonadotropin-releasing hormone （GnRH）. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to determine the expression levels of SIRT1， Kisspeptin， kisspeptin receptor （GPR54）， and GnRH in the ARC region of the hypothalamus and gonadotropin-releasing hormone receptor （GnRH-R） in pituitary. ResultsCompared with the sham operation group， rats in the model group had a significantly increased body weight （P0.01）， reduced wet weight and index of uterus （P0.01）， endometrial thinning or atrophy， glandular atrophy， and a decreasing number of glands. Additionally， serum levels of E₂ and the expression of SIRT1 in the ARC region of the hypothalamus significantly decreased （P0.01）. Serum levels of FSH， LH， and GnRH， the expression of Kisspeptin， GPR54， and GnRH in the ARC region of the hypothalamus， and GnRH-R in pituitary significantly increased （P0.01）. Compared with the model group， the estradiol valerate group and the high-， medium-dose modified Erxian decoction groups had significantly reduced body weight， serum levels of FSH， LH， and GnRH， and expression of Kisspeptin， GPR54， and GnRH in the ARC region of the hypothalamus and GnRH-R in pituitary （P0.05， P0.01） and significantly increased wet weight and index of uterus， serum level of E₂， and expression of SIRT1 in the ARC region of the hypothalamus （P0.05， P0.01）. In addition， they showed thickened endometrium， increased number of endometrial glands， and improved glandular atrophy. ConclusionModified Erxian decoction regulates the function of the HPG axis through multi-targets， and its mechanism of action may be related to the up-regulation of the expression of SIRT1 in the ARC region of the hypothalamus， the inhibition of the over-activation of the Kisspeptin/GnRH signaling pathway， the regulation of the expression of GnRH-R in the pituitary， the restoration of secretion balance of gonadotropins， and the elevation of the estrogen level. This study provides an experimental basis for the interpretation of the scientific connotation of modified Erxian decoction in the treatment of perimenopausal syndrome and a theoretical reference for the development of a novel therapeutic strategy based on the SIRT1/Kisspeptin/GnRH pathway.

Objective:To investigate the potential value of cerebral glucose metabolism characteristics in anti-leucine-rich glioma-inactivated protein 1 (LGI1) antibody-related encephalitic patients during acute phase as the clinical indicator of disease outcomes.Methods:From October 2019 to December 2023, 28 patients (18 males, 10 females; age (56.6±11.9) year) with anti-LGI1 antibody-related encephalitis diagnosed at Huashan Hospital, Fudan University were prospectively enrolled. All patients received baseline brain 18F-FDG PET imaging and were divided into different subgroups according to the prognosis (good prognosis and poor prognosis groups) and recurrence (recurrence and non-recurrence groups) after follow-up. The difference of Montreal Cognitive Assessment (MoCA) score between the two groups was compared by Mann-Whitney U test. Statistical parametric mapping (SPM) analysis was used to analyze the PET images of different groups by independent-sample t test, and the characteristics of cerebral glucose metabolism of patients with different outcomes were obtained. Results:MoCA scores between the recurrence group ( n=6) and the non-recurrence group ( n=22; 14.0(9.8, 20.5) vs 22.0(18.0, 24.0); Z=2.17, P=0.030), and between the poor prognosis group ( n=13) and the good prognosis group ( n=15; 14.0(10.0, 22.0) vs 22.0(19.8, 25.3); Z=2.47, P=0.013) were significantly different. Compared with the good prognosis group, the cerebral glucose metabolism in the poor prognosis group was decreased in the bilateral frontal lobe, lateral temporal lobe, inferior parietal lobule and cingulate gyrus, but increased in the brainstem, bilateral lentiform nucleus and bilateral paracentral lobule/postcentral gyrus (all t=1.71, all P<0.05). Compared with the non-recurrence group, the metabolism of bilateral medial frontal gyrus, anterior cingulate gyrus, bilateral insula, superior temporal gyrus and thalamus decreased in the recurrence group, while the metabolism of bilateral precentral gyrus, inferior frontal gyrus and bilateral lentiform nucleus increased (all t=1.71, all P<0.05). Conclusion:18F-FDG PET imaging reveals the differences in brain metabolism of anti-LGI1 antibody-related encephalitic patients at baseline with different outcomes (prognosis, recurrence or not), which can provide a new perspective for the clinical evaluation of the disease at baseline.
