Objective :
To investigate the mechanism of puerarin in the treatment of rheumatoid arthritis(RA) by network pharmacology and animal experiments.
Methods :
Traditional Chinese Medicine Systems Pharmcolog Database(TCMSP) and SwissTargetPrediction database were used to collect puerarin targets, and the targets of RA were obtained from GeneCards database and OMIM database. The PPI network was established by Cytoscape 3.7.2 software. Gene ontology(GO) function and Kyotoencyclopedia of genes(KEGG) enrichment analysis were performed through the Metascape database. RA rat-collagen-induced arthritis(CIA) model was reproduced using type Ⅱ collagen emulsion, 49 Wistar rats were randomly assigned to seven groups: control group, CIA model group, low-dose, medium-dose and high-dose puerarin group, methotrexate group, Tripterysium Glycosides Tablets group. Except for the control group, the other groups were given continuous gavage for 28 days after the CIA in rats model were prepared. The redness and swelling of the joints and ankle joint pathological changes were observed in each group. Western blot was used to detect the expression of Glycogen synthase kinase3β(GSK-3β), beta-catenin(β-catenin) proteins in the synovium. Real-time quantitative polymerase chain reaction(qPCR) was used to detect the expression of GSK-3β, β-catenin and c-Myc mRNA in the synovium.
Results :
Puerarin had 134 targets genes, RA had 5 821 target genes, and there were 102 overlapping target genes of puerarin and RA. It involved 184 signaling pathways, including JAK-STAT signaling pathway, NF-κB signaling pathway, Wnt signaling pathway, et al. The results of animal experiments showed that after the intervention of M-puerarin and MTX, the symptoms of redness and swelling of the hind foot were alleviated, the inflammatory cell infiltration in the synovium of the joint was significantly reduced, and the damage of cartilage and bone tissue was reduced. Compared with CIA group, the expressions of GSK-3β, β-catenin protein and GSK-3β, β-catenin and c-Myc mRNA in synovial tissue of rats after M-puerarin intervention decreased(P<0.05).
Conclusion
Puerarin has the characteristic of multi-components, multi-targets and multi-pathway intervention in RA. Puerarin may alleviate synovial hyperplasia, reduce articular cartilage erosion and bone destruction in CIA in rats by inhibiting Wnt/β-catenin signaling pathway.

ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke (AIS) patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method,the patients were assigned into a control group (32 cases) and an observation group (31 cases). The control group received conventional Western medical treatment,and the observation group took 200 mL Tongnaoyin after meals,twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment,the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans,rKep,and rVe values were obtained from the region of interest (ROI) of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment,the NIHSS and mRS scores declined in both groups,and the observation group had lower scores than the control group (P<0.05). After treatment,the rKtrans and rVe in the observation group were lower than those in the control group (P<0.01). ConclusionCompared with conventional Western medical treatment alone,conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients,thereby ameliorating neurological impairment after AIS to improve the prognosis.

ObjectiveTo explore the mechanism by which Buyang Huanwutang regulates the glutathione peroxidase 4 (GPX4)-acyl-CoA synthetase long-chain family member 4 (ACSL4) axis to inhibit ferroptosis and promote neurological functional recovery after spinal cord injury (SCI). MethodsNinety rats were randomly divided into five groups: sham operation group, model group, low-dose Buyang Huanwutang group (12.5 g·kg-1), high-dose Buyang Huanwutang group (25 g·kg-1), and Buyang Huanwutang + inhibitor group (25 g·kg-1 + 5 g·kg-1 RSL3). The SCI model was established by using the allen method. Tissue was collected on the 7th and 28th days after operation. Motor function was assessed by using the Basso-Beattie-Bresnahan (BBB) scale. Hematoxylin-eosin (HE), Nissl, and Luxol fast blue (LFB) staining were performed to observe spinal cord histopathology. Transmission electron microscopy was used to examine mitochondrial ultrastructure. Immunofluorescence staining was used to detect the number of NeuN-positive cells and the fluorescence intensity of myelin basic protein (MBP), GPX4, and ACSL4. Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) was used to analyze the mRNA expression of GPX4 and ACSL4. Enzyme linked immunosorbent assay (ELISA) was performed to measure the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD). Colorimetric assays were used to determine the iron content in spinal cord tissue. ResultsCompared to the sham operation group, the model group exhibited significantly reduced BBB scores (P<0.01), severe pathological damage in spinal cord tissue, and marked mitochondrial ultrastructural disruption. In addition, the model group showed a decrease in the number of NeuN-positive cells (P<0.01), reduced fluorescence intensity of MBP and GPX4 (P<0.01), lower levels of GSH and SOD (P<0.01), and downregulated mRNA expression of GPX4 (P<0.01). Moreover, compared to the sham operation group, the model group had elevated levels of ROS, MDA, and tissue iron content (P<0.01), along with increased fluorescence intensity and mRNA expression of ACSL4 (P<0.01). Compared with the model group and Buyang Huanwutang + inhibitor group, the Buyang Huanwutang group showed significantly improved BBB scores (P<0.05, P<0.01) and exhibited less severe spinal cord tissue damage, reduced edema and inflammatory cell infiltration, increased neuronal survival, and more intact myelin structures. Additionally, mitochondrial ultrastructure was significantly improved in the Buyang Huanwutang group. Compared to the model group and Buyang Huanwutang + inhibitor group, the Buyang Huanwutang group significantly increased the number of NeuN-positive cells and the fluorescence intensity of MBP (P<0.05, P<0.01). Furthermore, Buyang Huanwutang significantly increased the fluorescence intensity and mRNA expression of GPX4 (P<0.01) and decreased the fluorescence intensity and mRNA expression of ACSL4 (P<0.01) compared to the model group and Buyang Huanwutang + inhibitor group. Finally, the Buyang Huanwutang group significantly decreased ROS, MDA, and tissue iron content (P<0.01) and significantly increased GSH and SOD levels (P<0.01) compared to the model group and Buyang Huanwutang + inhibitor group. ConclusionBuyang Huanwutang inhibits ferroptosis through the GPX4/ACSL4 axis, reduces secondary neuronal and myelin injury and oxidative stress, and ultimately promotes the recovery of neurological function.

ObjectiveTo investigate the effect of icariin (ICA) on steroid-induced ferroptosis in bone microvascular endothelial cells (BMECs). MethodsRat BMECs were selected and treated with 500 mg·L-1 hydrocortisone for 1.5 h to establish a ferroptosis model of BMECs. The experimental cells were divided into a blank group, hormone group (500 mg·L-1 hydrocortisone), ICA group (500 mg·L-1 hydrocortisone + 34 mg·L-1 ICA), and ferroptosis agonist group (500 mg·L-1 hydrocortisone + 34 mg·L-1 ICA + 2.7 mg·L-1 erastin). Cell viability was detected by CCK-8. The levels of ferrous ion, glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), and reactive oxygen species (ROS) were detected by related kit species. The ferroptosis-related proteins, such as glutathione peroxidase 4(GPX4), ferritin light chain (FTL), and transferrin receptor protein1 (sTfR) were detected by Western blot, as well as autophagy-related proteins including microtubule-associated protein 1 light chain 3B (LC3B), Beclin1, B-cell lymphoma-2 (Bcl-2), and Caspase-3. Results500 mg·L-1 hydrocortisone intervention for 1.5 h could effectively induce ferroptosis in BMECs, and ferroptosis levels could reach a peak as the intervention continued. In terms of cellular antioxidant capacity, compared with those in the blank group, the cell vitality, GSH in the hormone group decreased significantly, and the levels of ROS, SOD, MDA, and ferrous ions were significantly increased (P<0.01). Compared with those in the hormone group, the cell viability, GSH were significantly increased, and the levels of ROS, SOD, MDA, and ferrous ions were decreased in the ICA group (P<0.01). Compared with those in the ICA group, the cell vitality, GSH in the ferroptosis agonist group decreased significantly, and the levels of ROS, SOD, MDA, and ferrous ions increased significantly (P<0.01). In terms of the relationship between ferroptosis and autophagy, compared with the blank group, the hormone group had significantly increased expression levels of LC3B, sTfR, Beclin1, and FTL and significantly decreased expression levels of GPX4 (P<0.01). Compared with the hormone group, The ICA group had significantly decreased expression levels of LC3B, sTfR, and FTL and significantly increased expression levels of Beclin 1 and GPX4 (P<0.01). Compared with those in the ICA group, the expression levels of LC3B, sTfR, and FTL increased in the rapamycin group, and those of Beclin 1 and GPX4 decreased (P<0.01). In terms of cell ferroptosis and apoptosis,compared with the blank group, the hormone group had significantly increased expression levels of FTL, sTfR and Caspase-3 and significantly decreased expression levels of GPX4, and Bcl-2 (P<0.01). Compared with the hormone group, the ICA group had significantly decreased expression levels of FTL, sTfR and Caspase-3 and significantly increased expression levels of GPX4, and Bcl-2 (P<0.01). Compared with those in the ICA group, the expression levels of FTL, sTfR and Caspase-3 in the ferroptosis agonist group were increased, and the expression levels of GPX4, and Bcl-2 were decreased (P<0.01). In terms of cell function,compared with that in the blank group, the ability of cell migration and tube formation was significantly decreased in the hormone group (P<0.01). Compared with that in the hormone group, the cell migration and tube formation ability in the ICA group were significantly increased (P<0.01). ConclusionFerroptosis is involved in steroid-induced damage in BMECs. ICA can inhibit steroid-induced ferroptosis in BMECs, and the mechanism may be associated with the inhibition of ferroptosis by regulating autophagy.

ObjectiveTo investigate the bacterial diversity in the rhizosphere soil and phyllosphere of Angelica sinensis and examine the effects of foliar applications of a composite bacterial agent,salicylic acid,and coronatine on the bacterial diversity,disease incidence,and plant yield,thus providing a theoretical basis and guidance for the artificial construction of functional minimal communities and the regulation of rhizosphere through foliar treatments. MethodsUnder continuous cropping conditions in the field,foliar applications of a composite bacterial agent,salicylic acid,coronatine,and sterile water were conducted. The 100-plant weight was measured via the conventional method,and the incidence of diseases was recorded. The microbial community composition,diversity,and inter-group differences in the phyllosphere and rhizosphere soil of A. sinensis were analyzed by 16S high-throughput sequencing,and the potential microbial functions were predicted. ResultsCompared with the blank control,foliar applications of salicylic acid and coronatine both significantly reduced the yield and root rot incidence of A. sinensis. The foliar application of salicylic acid decreased the content of ferulic acid and increased that of ligustilide. The foliar application of coronatine increased the content of both ferulic acid and ligustilide. The microbial communities and functions in the phyllosphere and rhizosphere soil were significantly different. The phyllosphere had lower microbial diversity,with all bacteria being Gram-negative,mainly Cyanobacteria and Proteobacteria with limited functions. The rhizosphere soil had higher microbial diversity,harboring dominant phyla including Proteobacteria,Actinobacteria,Acidobacteria,and Bacteroidetes with rich functions. All foliar treatments regulated the microbial community in the rhizosphere soil,with a more significant effect on the microbial community in the rhizosphere soil than that in the phyllosphere. The coronatine treatment significantly reduced the abundance of Proteobacteria and nitrate-reducing and aromatic compound-degrading microorganisms in the rhizosphere soil,thus affecting nutrient cycling and autotoxic substance degradation and leading to a yield reduction. Compared with the salicylic acid treatment,the coronatine treatment significantly increased the abundance of Bacillus and Streptomyces in the rhizosphere soil,demonstrating enhanced disease control efficacy. ConclusionFoliar application of coronatine and salicylic acid can significantly regulate the composition and function of bacterial communities in the rhizosphere soil,thereby reducing the disease incidence and the plant yield.

Liver cancer has high prevalence and mortality rates around the world, and its development and progression are closely associated with the interaction between the tumor microenvironment and tumor-associated macrophages (TAMs). TAMs play a significant role in immune suppression, immune escape, cell proliferation, invasion, metastasis, and drug resistance in liver cancer. Traditional Chinese medicine (TCM), with its unique therapeutic concepts and methods, has shown great potential in regulating TAMs and improving the prognosis of liver cancer. This article reviews the role and molecular mechanisms of TCM in regulating TAMs for the treatment of liver cancer, discusses the key role of TAMs in the progression of liver cancer, and analyzes the impact of Chinese medicinal components on the recruitment, polarization, and activity of TAMs and the expression of related factors based on TCM theory. Studies have shown that TCM can regulate the polarization state of TAMs, promote the formation of M1-type antitumor macrophages, and inhibit the activity of M2-type tumor macrophages, thereby playing a role in inhibiting the proliferation of liver cancer cells, promoting apoptosis, inhibiting angiogenesis, and enhancing immune response. In addition, this article also summarizes the molecular targets and mechanisms of action of TCM monomers, compound prescriptions, and novel preparations in the treatment of liver cancer, such as inhibiting the secretion of cytokines by TAMs, regulating signaling pathways, and affecting metabolic pathways, in order to provide a scientific basis for the application of TCM in liver cancer treatment and offer new ideas for immunotherapy for liver cancer.

ObjectiveTo investigate the recurrence of ischemic stroke (IS) and to analyze the association between four indices of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) and the risk of IS recurrence by analyzing the follow-up data related to IS in the community-based natural population of Songjiang District, Shanghai, so as to provide a scientific basis for improving the prognosis of stroke patients in the community and controlling IS recurrence. MethodsA prospective follow-up study was conducted among the IS patients in the community-based cohort population, collecting data about patient’s age, gender, disease history, biochemical indicators, and etc. Cox regression model and restricted cubic spline model were used to analyze the relationship between different levels of plasma lipids and the recurrence of IS in these patients. ResultsA total of 1 368 patients with IS were included. The total follow-up duration was 7 171.46 person-years, with a median follow-up time of 6.24 years. There were 420 cases of IS recurrence, resulting in a cumulative recurrence rate of 30.70%. The results of multivariate Cox regression analysis showed that the recurrence risk of IS was reduced when the baseline TC and LDL-C levels of IS patients were in the ranges of 4.65‒5.67 mmol·L-1 and 2.52‒3.46 mmol·L-1, respectively. The results of restricted cubic spline analysis showed a U-shaped relationship between baseline TC and LDL-C levels and the recurrence risk in IS patients. ConclusionThe cumulative recurrence rate of patients with IS in the community of Songjiang District in Shanghai is high, and the levels of TC and LDL-C at baseline survey are correlated with the recurrence of IS in these patients. It is suggested to pay more attention to the levels of LDL-C and TC in patients with IS, so as to improve the prognosis.

Objective To determine the fitting parameters for the Archer equation (using shielding transmission factor as variables and shielding material thickness as functions) and quadratic equation with one unknown (using lead equivalent as variables and shielding material thickness as functions) for common radiation protection shielding materials, enabling calculation of lead equivalent or required shielding material thickness. Methods The shielding transmission factor of red brick, lime-sand brick, barium sulfate protective coating, lead glass, and standard lead sheets was measured under narrow-beam X-ray exposure, with tube voltages ranging from 70 to 150 kV. The data of standard lead sheet was used as the reference for lead equivalent. Related parameters were fitted according to the Archer equation recommended by the National Council on Radiation Protection and Measurements Report No. 147 and quadratic equation with one unknown relating lead equivalence to shielding materials thickness. Results The coefficients of determination for the quadratic equation with one unknown of red brick, lime-sand brick, barium sulfate coating, lead glass exceeded 0.999 3. Under 120 kV X-rays, 1 and 2 mmPb were equivalent to 101.02 and 171.09 mm red brick, 121.21 and 204.43 mm lime-sand brick, 10.63 and 24.27 mm barium sulfate coating, and 4.21 and 9.39 mm lead glass. Conclusion The Archer equation and quadratic equation with one unknown from 120 kV or higher tube voltage conditions derived in this study can be applied to calculate lead equivalent or required thickness of shielding materials under both primary and scattered radiation, without linear extrapolation. They provide a basis for radiation shielding design in radiation diagnosis and treatment facilities and for occupational radiation hazard assessments.
