Objective To investigate the effect of intermittent θ burst stimulation （iTBS） combined with cognitive training in improving the cognitive and neurological functions of patients with post-stroke cognitive impairment （PSCI）. Methods A total of 80 patients with PSCI who were admitted to our hospital from July 2022 to July 2024 were enrolled in the study， and they were randomly divided into observation group and control group， with 40 patients in each group. The patients in the observation group received iTBS combined with cognitive training， while those in the control group received conventional treatment combined with cognitive training. The two groups were compared in terms of the changes in cognitive function， daily memory function， activities of daily living， cognitive flexibility， and neurological function after treatment. Results After 4 weeks of treatment， both groups had improvement in cognitive function， and compared with the control group receiving cognitive training alone， the observation group had significant increases in the scores of cognitive function， daily memory function， and activities of daily living （P<0.05）， with significant improvements in cognitive flexibility and neurological function （P<0.05）. Conclusion The combination of iTBS and cognitive training can significantly improve cognitive and neurological functions in patients with PSCI.

Objective To investigate the effects of Xuetong capsule on blood lipids and liver lesion in hyperlipidemic model animals. Methods Sixty ICR mice were randomly divided into six groups. The normal control group was fed with normal diet, the other groups were fed with high-fat diet to induce hyperlipidemia. After four weeks feeding, the three groups were given low, middle, and high doses of Xuetong capsules （0.5, 1.0, and 2.0 g/kg） by gavage, and the positive drug control group was given atorvastatin calcium （1.5 mg/kg） by gavage. The model group was given solvent （0.5% carboxymethyl cellulose sodium）. After treatment for 8 weeks, the body weight, organ index, blood lipids, blood glucose and liver function index were measured. The liver oil red staining was used to determine the lipid droplet content, and quantitative PCR was used to detect the expression of inflammatory factors TNF-α, IL-6, and IL-1β. Results The body weight, the weight of liver and spleen were significantly increased by high-fat diet. High-fat diet increased the organ indexes of the liver and spleen, the degree of liver oil red staining, and also significantly increased the levels of glucose, triglyceride （TG）, cholesterol （CHOL）, and low-density lipoprotein cholesterol （LDL-C） in serum. Compared with the model group, the level of TG has no significant change in low, middle and high doses groups. The level of CHOL in serum was reduced by Xuetong capsule with a dose dependent manner. There were significant difference between the model group and middle, high doses groups. The results of LDL-C were similar, the level of LDL-C was significantly reduced by middle and high doses groups [middle dose (0.55±0.21) mmol/L, high dose (0.52±0.22) mmol/L vs (0.81±0.29) mmol/L in model group, P<0.05]. Compared with the normal control, there was no significant difference in HDL-C levels between the high-fat model and each drug-treated group. Liver function showed that Xuetong capsules significantly reduced the degree of liver oil red staining and decreased the level of alanine aminotransferase （ALT） induced by high-fat diet. The body weight, the weight and organ indexes of liver and spleen were significantly reduced by positive drug control group. The levels of CHOL, LDL-C, and TG, and the degree of liver oil red staining were also significantly reduced in positive drug control group. Further studies have shown that high dose of Xuetong capsules significantly reduced the expression of TNF-α and IL-6 induced by high-fat diet （P<0.05）, while the reduction of IL-1β was not so significant （P>0.05）. Conclusion Xuetong capsules significantly reduced the body weight of animals with high fat, liver size, fat deposition, inflammatory damage and also significantly reduced blood lipid CHOL and LDL-C levels and transaminase elevation. The above effects may be related to Xuetong capsules reducing the expression of inflammatory factors such as TNF-α and IL-6 in the liver.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

ObjectiveTo investigate the effect and mechanism of Qingre Sanzhuo decoction in treating gouty arthritis （GA） combined with hyperuricaemia （HUA）. MethodsSixty male SD rats were randomized into normal， model， colchicine （0.5 mg·kg^-1）， and low-， medium-， and high-dose （17， 34， 68 g·kg^-1， respectively） Qingre Sanzhuo decoction groups （n=10）. The rats in other groups except the normal group were treated with the modified method for the modeling of GA combined with HUA. The drug intervention groups were administrated with corresponding drugs by gavage in the afternoon every day and the normal group and the model group were administrated with an equal volume of sterile normal saline by gavage. The level of uric acid （SUA） in the serum was measured 2 h after the last administration. The degree of ankle joint swelling was calculated 0.5， 12， 24， 48 h after modeling， and joint inflammation was scored. The pathological changes of ankle joints were observed by hematoxylin-eosin staining， and the serum levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， C reactive protein （CRP）， and interleukin-18 （IL-18） were measured by enzyme-linked immunosorbent assay. Real-time PCR was performed to determine the mRNA levels of NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing CARD （ASC）， cysteinyl aspartate-specific protease-1 （Caspase-1）， gasdermin D （GSDMD）， and nuclear factor-kappa B （NF-κB） in the synovial tissue of ankle joints. Western blot was employed to determine the protein levels of NLRP3， ASC， and Caspase-1 in ankle joints. The immunohistochemical method was used to detect the expression of GSDMD and NF-κB in the synovial tissue of ankle joints. ResultsCompared with the normal group， the model group showed increased SUA in the serum （P<0.05）， ankle joint swelling and joint inflammation （P<0.05）， increased number of blood vessels in the synovium， inflammatory cell foci in the synovial bursa， elevated serum levels of TNF-α， IL-1β， CRP， and IL-18 （P<0.05）， and up-regulated mRNA and protein levels of NLRP3， ASC， Caspase-1， GSDMD， and NF-κB in the synovial tissue of ankle joints （P<0.05）. Compared with the model group， the medium- and high-dose Qingre Sanzhuo decoction groups showed reduced SUA in the serum （P<0.05）， alleviated ankle joint swelling and joint inflammation （P<0.05）， lowered serum levels of TNF-α， IL-1β， CRP， and IL-18 （P<0.05）， and down-regulated mRNA and protein levels of NLRP3， ASC， Caspase-1， GSDMD， and NF-κB in the synovial tissue of ankle joints （P<0.05）. However， in terms of ameliorating the pathological changes of ankle joints， only the high-dose Qingre Sanzhuo decoction group showed normal morphology of the synovial membrane of ankle joints and no obvious lesion in the articular cartilage. ConclusionQingre Sanzhuo decoction may play a role in preventing and controlling GA combined with HUA by down-regulating the activity of NLRP3/ASC/Caspase-1 pathway and inhibiting the expression of inflammatory cytokines， such as TNF-α， IL-1β， CRP， and IL-18.

ObjectiveTo investigate the effect of Naoqingtong decoction （NQT） on the kidney damage and the inflammatory factors NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in spontaneously hypertensive rats （SHRs）. MethodsTwenty-four SHRs were randomized into a model group， a low-dose （12.9 g·kg^-1·d^-1） NQT （NQT-L） group， a high-dose （25.8 g·kg^-1·d^-1） NQT group （NQT-H）， and a captopril （CTP， 20 mg·kg^-1·d^-1） group， with 6 rats in each group. In addition， 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period， and the blood pressure was measured periodically. At the end of intervention， the body mass was weighed， and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue. ResultsDuring the experiment period， the control group had normal mental status， food intake， and activity， while the model group showed thinning of hair， loss of luster， reduced activity， loss of appetite， fecal adhesion， and irritability， and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats， which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group （P<0.01）. Compared with the model group， drug interventions lowered the systolic and diastolic blood pressure （P<0.05， P<0.01）. Compared with the control group， the model group showed severe pathological damage in the kidney tissue， which was alleviated in each drug intervention group. Compared with the control group， the model group showed up-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. Compared with the model group， the drug intervention groups showed down-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes， suppressing renal inflammation， and ameliorating hypertensive kidney damage.

ObjectiveTo investigate the effect of blueberry-derived tectorigenin （TEC） on hepatocellular carcinoma cell lines HepG2 and Huh7 and its mechanism. MethodsTEC was extracted from blueberries and purified， and a bioinformatics analysis was performed to identify potential target genes and signaling pathways. HepG2 and Huh7 cell lines were used and divided into 0， 30， 60， and 90 μg/mL groups according to the concentration of TEC. CCK-8 assay was used to measure cell viability； wound healing assay and Transwell assay were used to assess the migration ability of cells； flow cytometry was used to measure cell apoptosis rate； Western Blot was used to measure the protein expression levels of CCNB1， p53， MDM2， Bax， Bcl-2， and active-Caspase 3. Cell models with low CCNB1 expression （NC group， si-NC group， si-NC+TEC group， si-CCNB1 group， and si-CCNB1+TEC group） and CCNB1 overexpression （OE-NC group， OE-NC+TEC group， OE-CCNB1 group， and OE-CCNB1+TEC group） were established to validate the targets. A one-way analysis of variance or two factors analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. The Wilcoxon signed rank sum test was used to compare the expression levels of genes between cancer tissue and paracancerous tissue. ResultsIn HepG2 and Huh7 cells under the same concentration of TEC， cell viability at 24 hours of TEC intervention was significantly lower than that at 12 and 48 hours （all P<0.05）， and at 24 hours of intervention， the TEC 90 μg/mL group had a significantly lower cell viability than the other groups （all P<0.05）. Therefore， TEC intervention for 24 hours at a concentration of 90 μg/mL was used for subsequent studies. Compared with the TEC 0 μg/mL group， the 30， 60， and 90 μg/mL groups had significant reductions in the number of migrated cells and wound healing rate （all P<0.05）， and compared with the NC group and si-NC group， the si-NC+TEC group and the si-CCNB1 group for HepG2 and Huh7 cells had significant reductions in the number of migrated cells and wound healing rate （all P<0.05）. Compared with the NC group and si-NC group， the si-NC+TEC group and the si-CCNB1 group for HepG2 and Huh7 cells had a significant increase in cell apoptosis rate （all P<0.05）. For HepG2 cells， compared with the 0 μg/mL group， the 30， 60， and 90 μg/mL groups had significant reductions in the protein expression levels of CCNB1 and Bcl-2 （all P<0.05）， and the 60 and 90 μg/mL groups had significant increases in the protein expression levels of p53， Bax， and active-Caspase 3 （all P<0.001） and a significant reduction in the protein expression level of MDM2 （both P<0.05）. For Huh7 cells， compared with the 0 μg/mL group， the 30， 60， and 90 μg/mL groups had a significant reduction in the protein expression level of CCNB1 （all P<0.01）； the 60 and 90 μg/mL groups had significant increases in the protein expression levels of p53 and Bax and a significant reduction in the protein expression level of MDM2 （all P<0.05）； the 90 μg/mL group had a significant reduction in the protein expression level of Bcl-2 and a significant increase in the protein expression level of active-Caspase 3 （both P<0.01）. Compared with the si-NC group， the si-NC+TEC group and the si-CCNB1 group for HepG2 and Huh7 cells had significant reductions in the protein expression levels of CCNB1， MDM2， and Bcl-2 and significant increases in the protein expression levels of p53 and Bax （all P<0.05）. Compared with the OE-NC group， the OE-NC+TEC group for HepG2 and Huh7 cells had significant reductions in the protein expression levels of CCNB1 and MDM2 and a significant increase in the protein expression level of p53 （all P<0.05）， while the OE-CCNB1 group had significant increases in the protein expression levels of CCNB1 and MDM2 and a significant reduction in the protein expression level of p53 （all P<0.05）， and there were no significant differences in the protein expression level of CCNB1， MDM2， and p53 between the OE-CCNB1 group and the OE-CCNB1+TEC group （all P>0.05）. ConclusionTEC can inhibit the proliferation and migration of HepG2 and Huh7 cells and promote their apoptosis in vitro， possibly by downregulating the expression of CCNB1 and activating the p53 signaling pathway.
