ObjectiveTo investigate the effects of Huanglian Jiedutang （HLJDT） on cognitive function in mice with ischemic stroke （IS） and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB （NF-κB） signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion （MCAO）. Sixty C57BL/6J mice were randomly assigned to five groups （n =12 per group）， i.e.， sham operation， model， HLJDT low-dose （3.9 g·kg^-1·d^-1）， HLJDT high-dose （7.8 g·kg^-1·d^-1）， and Ginkgo biloba extract （GBE， 31.2 mg·kg^-1·d^-1）. Post-operatively， neurological deficit scores （Longa score）， cerebral infarct volume assessed by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and brain water content were evaluated. Learning and memory were assessed using new object recognition （NOR） and fear conditioning （FC） tests. Hippocampal pathology was examined via hematoxylin and eosin （HE） staining. Immunofluorescence detected expression of glial fibrillary acidic protein （GFAP， astrocyte marker）， cellular oncogene Fos （c-Fos， neuronal activation marker）， and glutamate decarboxylase 65 （GAD65）. Western blot measured nuclear factor-κB inhibitor protein α （IκBα）， phosphorylated IκBα （p-IκBα）， NF-κB p65， phosphorylated NF-κB p65 （p-NF-κB p65）， ionic calcium binding adapter molecule 1 （Iba-1）， tumor necrosis factor （TNF）-α， interleukin （IL）-1β， and apoptosis-related proteins， such as cleaved cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma 2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Real-time quantitative PCR （Real-time PCR） was used to assess mRNA levels of Iba-1， TNF-α， IL-1β， NF-κB p65， cleaved Caspase-3， Bax， and Bcl-2. ResultsCompared with the sham group， the model group exhibited significantly increased neurological deficit scores， brain water content， and cerebral infarct volume （P<0.01）. Hippocampal CA1 neurons were disorganized， showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced （P<0.01）. GFAP and c-Fos expression were increased， while GAD65 expression was decreased （P<0.01）. Cleaved Caspase-3 and Bax were upregulated， Bcl-2 was downregulated， and the Bax/Bcl-2 ratio was elevated （P<0.01）. Expression levels of p-IκBα， p-NF-κB p65， IL-1β， TNF-α， and Iba-1 were significantly increased （P<0.01）. Compared with the model group， HLJDT high-dose， low-dose， and GBE groups showed significant improvements in all parameters （P<0.01）. Among them， the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests （P<0.01）. In this group， GFAP and c-Fos decreased， GAD65 increased （P<0.01）， apoptosis-related protein expression was reversed， and NF-κB signaling and related inflammatory factor expression were suppressed （P<0.01）. ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS， potentially by inhibiting the NF-κB signaling pathway， thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

Objective To investigate the proportion of Th17 cells,Th1-like Th17 cells and FoxP3+Th17 cells in bone marrow of patients with myelodysplastic syndrome(MDS),the expression of interleukin-17A(IL-17A)in bone marrow supernatant and its clinical significance.Methods Forty MDS patients(MDS group)and 18 patients with nutritional anemia(control group)were selected.MDS patients were classified into the low blast(MDS-LB)group(19 cases)and the increased blast(MDS-IB)group(21 cases,including 11 cases of type IB1 and 10 cases of type IB2)based on morphological definition.The MDS patients were scored according to the revised International Prognostic Scoring System(IPSS-R),with 18 cases in the low-risk group(≤4.5)and 22 cases in the high-risk group(>4.5).Flow cytometry was used to detect the proportion of Th17 cells,Th1-like Th17 cells and FoxP3+Th17 cells in bone marrow of the MDS group and the control group.Enzyme-linked immunosorbent assay(ELISA)was used to detect the level of IL-17A in bone marrow supernatant of the above samples.Results The proportion of Th17 cells and the level of IL-17A were higher in patients of the MDS group than those in the control group(P＜0.05).According to the median expression level of IL-17A,the MDS group was divided into the low-expression group(＜13.71 ng/L,20 cases)and the high-expression group(≥13.71 ng/L,20 cases).Compared with the low-expression group,there were higher proportion of patients with blast cells＜5%and low-risk patients(P＜0.05)in the high-expression group.Compared with the IL-17A low-expression group,the IL-17A high-expression group had a higher proportion of patients with blast cells＜5%and relatively low-risk patients(P＜0.05).Compared with the low-risk patients,high-risk patients had a lower proportion of Th17 cells,IL-17A levels and Th1-like Th17 cells,and a higher proportion of FoxP3+Th17 cells(P＜0.05).Compared with the MDS-LB group,the MDS-IB group had a lower proportion of Th17 cells,IL-17A levels and Th1-like Th17 cells,and a higher proportion of FoxP3+Th17 cells(P＜0.05).Conclusion The proportion of Th17 cells and the level of IL-17A are significantly increased in MDS patients.The decreased proportion of Th1-like Th17 cells and the increased proportion of FoxP3+Th17 cells may be related to the increased proportion of blast cells and higher risk stratification in patients.

Objective:To evaluate the effect of arctigenin (ARG) on cognitive dysfunction induced by sevoflurane anesthesia in aged rats and the role of autophagy-mediated pyroptosis.Methods:Fifty SPF male Sprague-Dawley rats, aged 18-20 months, weighing 550-600 g, were divided into 5 groups ( n=10 each) using a random number table method: control group (C group), sevoflurane anesthesia group (Sev group), sevoflurane anesthesia+ ARG group (Sev+ ARG group), sevoflurane anesthesia+ autophagy inducer rapamycin group (Sev+ RAPA group), and sevoflurane anesthesia+ ARG+ autophagy inhibitor 3-methyladenine (3-MA) group (Sev+ ARG+ 3-MA group). Except for group C, the rats in the other groups inhaled 6% sevoflurane for 3 h to establish the cognitive impairment model. At 30 min before anesthesia, ARG 20 mg/kg was intraperitoneally injected in Sev+ ARG group, rapamycin 7.5 mg/kg was intraperitoneally injected in Sev+ RAPA group, and ARG 20 mg/kg (dissolved in dimethyl sulfoxide) was intraperitoneally injected, followed by immediate intraperitoneal injection of 3-MA 1.5 mg/kg in Sev+ ARG+ 3-MA group. The equal volume of dimethyl sulfoxide was intraperitoneally injected in C group and Sev group. The Morris water maze test was conducted to assess the cognitive function at 48 h after the end of administration. After completion of the Morris water maze test, the hippocampal tissue was taken under deep anesthesia for observation of the pathological changes (after HE staining) which were scored and for determination of neuronal pyroptosis (after propidium iodide staining) and expression of neuronal autophagy-related proteins (microtubule-associated protein 1 light chain 3 [LC3], Beclin-1, p62), pyroptosis-related proteins (NOD-like receptor protein 3 [NLRP3], apoptosis-associated speck-like protein containing a CARD [ASC], pro-cysteine aspartate-specific protease 1 [pro-caspase-1], cleaved-caspase-1, gasdermin D [GSDMD], and N-terminal fragment of gasdermin D [GSDMD-N], interleukin-1β [IL-1β] and IL-18). Results:Compared with C group, the escape latency was significantly prolonged, the time of staying at the original platform quadrant was shortened, the number of crossing the original platform was reduced, the hippocampal injury score and neuronal pyroptosis rate were increased, LC3Ⅱ/LC3Ⅰ ratio was decreased, the expression of Beclin-1 was down-regulated, the expression of p62, NLRP3, ASC, IL-1β and IL-18 was up-regulated, and the cleaved-caspase-1/pro-caspase-1 ratio and GSDMD-N/GSDMD ratio were increased in Sev group ( P<0.05). Compared with Sev group, the escape latency was significantly shortened, the time of staying at the original platform quadrant was prolonged, the number of crossing the original platform was increased, the hippocampal injury score and neuronal pyroptosis rate were decreased, LC3Ⅱ/LC3Ⅰ ratio was increased, the expression of Beclin-1 was up-regulated, the expression of p62, NLRP3, ASC, IL-1β and IL-18 was down-regulated, and the cleaved-caspase-1/pro-caspase-1 ratio and GSDMD-N/GSDMD ratio were decreased in Sev+ ARG group and Sev+ RAPA group ( P<0.05). Compared with Sev+ ARG group, the escape latency was significantly prolonged, the time of staying at the original platform quadrant was shortened, the number of crossing the original platform was reduced, the hippocampal injury score and neuronal pyroptosis rate were increased, LC3Ⅱ/LC3Ⅰ ratio was decreased, the expression of Beclin-1 was down-regulated, the expression of p62, NLRP3, ASC, IL-1β and IL-18 was up-regulated, and the cleaved-caspase-1/pro-caspase-1 ratio and GSDMD-N/GSDMD ratio were increased in Sev+ ARG+ 3-MA group ( P<0.05). Conclusions:AGR can alleviate sevoflurane anesthesia-induced cognitive dysfunction in aged rats, and the mechanism is related to reduction of autophagy-mediated cell pyroptosis.

Aim To investigate the effect of hydrogen sulfide on macrophage calcification and its underlying mo-lecular mechanisms.Methods Oil red O staining was used to observe intracellular lipid accumulation,and von Kossa staining and atomic absorption spectroscopy were used for morphological and quantitative analysis of calcium deposition and intracellular calcium content in a mononuclear macrophage calcification model.Western blot and RT-PCR were used to detect the mRNA and protein expression of osteopontin(OPN)at different doses and treatment times of hydrogen sulfide.At the same time,Western blot was used to detect the expression changes of early growth response factor 1(EGR1),endo-plasmic reticulum stress-related markers C/EBP homologous protein(CHOP)and glucose-regulated protein 78(GRP78).Reactive oxygen species levels were evaluated by fluorescence probe staining,and the effect of hydrogen sulfide on macro-phage calcification was evaluated by combining von Kossa staining and calcium ion fluorescence probe staining.The mo-lecular mechanisms of hydrogen sulfide affecting macrophage calcification were explored by interfering with EGR1 expression and using endoplasmic reticulum stress inhibitor 4-phenylbutyric acid(4-PBA).Results Compared with oxidized low density lipoprotein(ox-LDL)group,β-glycerophosphate(β-GP)+40 g/L ox-LDL group showed a significant increase in intracellular lipid accumulation,while hydrogen sulfide significantly inhibited macrophage calcification in a con-centration-and time-dependent manner.Compared with the β-GP+ox LDL group,the most significant effect was observed after incubation with 100 μmol/L NaHS for 4 days.The hydrogen sulfide group showed a 66％decrease in intracellular calcium content(P＜0.01),a 71％decrease in intercellular calcium deposition(P＜0.01),and a 50％and 48％decrease in OPN mRNA and protein expression,respectively(P＜0.05).Hydrogen sulfide treatment upregulated the ex-pression of EGR1 by 21％,while downregulating the expression of CHOP and GRP78 by 58％and 59％,respectively(P＜0.01).The endoplasmic reticulum stress inhibitor 4-PBA could downregulate OPN expression by 73％(P＜0.01),while interfering with EGR1 expression completely counteracts the inhibitory effect of hydrogen sulfide on OPN expression and calcium deposition(P＜0.01).Conclusion Hydrogen sulfide significantly inhibits macrophage calcification by upregulating EGR1 expression and suppressing endoplasmic reticulum stress.

Chinese medicinal materials serve as the material foundation of traditional Chinese medicine （TCM） culture. The sustainable development of Chinese medicinal material resources is a focal point in the modernization of TCM. With the increasing scarcity of Chinese medicinal material resources， the expansion of new Chinese medicinal material resources has become a crucial means for the sustainable utilization of these resources. New Chinese medicinal material resources refer to natural resources that have been newly discovered or developed， possessing potential medicinal value or healthcare functions， which fall outside the traditional application scope of herbal medicines. These resources have not yet been widely recognized or applied within the framework of traditional TCM theory. They specifically include artificial substitutes for endangered medicinal materials， new medicinal parts of medicinal plants， medicinal materials with expanded clinical applications， and foreign medicinal resources. The rational compatability and formulation of new Chinese medicinal material resources are essential pathways for integrating them into the TCM system. Due to the weak foundational research on new Chinese medicinal material resources in China， the characteristics of these resources that align with the TCM theory are not yet fully understood， posing numerous constraints on formulating prescriptions based on the traditional compatibility principles of TCM. This paper integrates the traditional formulation theory of TCM with modern data integration methods， proposing four formulation models for new TCM resources： synergistic compatibility， substitutive compatibility， symptom-based compatibility， and efficacy semantic compatibility. These models provide new insights for the application of new Chinese medicinal material resources， not only facilitating their rational use in clinical practice but also offering theoretical support for the development and compatibility research of these resources.
