Successful Administration of Kampo Medicine and Acupuncture Treatment to Improve Erythromelalgia: A Case Report.

Erythromelalgia is a rare disease characterized by a triad of recurrent burning pain, redness with pain, and hot flashes in the legs during attacks. We report the case of a 40-year-old woman who suffered from refractory erythromelalgia for 15 years and was successfully managed with Kampo medicine and acupuncture. Her pain was refractory to seven types of oral medications and intravenous lidocaine injections. Byakkokaninjinto was also administered for concomitant polydipsia in addition to acupuncture, unseiin, orengedokuto, and sokeikakketsuto. Because erythromelalgia has no established treatment, traditional Kampo medicine combined with acupuncture may help improve the quality of life of affected patients.

The effects of Qingchang Ligan formula on hepatic encephalopathy in mouse model: results from gut microbiome-metabolomics analysis.

Background: Hepatic encephalopathy (HE) is a neurological disorder resulting from advanced liver injury. HE has a high mortality rate and poor prognosis. The pathogenesis of HE is still unclear, which has led to the lack of a satisfactory specific treatment method. There is increasing evidence that the intestinal flora affects the communication between the gut and the brain in the pathogenesis of HE. Adjusting the intestinal flora has had a beneficial effect on HE in recent studies, and the Qingchang Ligan formula (QCLG) has been shown in previous studies to regulate intestinal flora and metabolites. In this study, we established a thioacetamide-induced HE mouse model to evaluate the protective effect of QCLG on HE and explore its potential mechanism, which also demonstrated that intestinal flora dysbiosis is involved in the pathogenesis of HE. Methods: Mice were intraperitoneally injected with thioacetamide (TAA, 150 mg/kg) to induce HE. Additionally, they were orally administered Qingchang Ligan Formula (QCLG) at a dose of 6.725 g/kg·d for seven days, while control mice received an equal volume of saline via gavage. Subsequently, samples were subjected to 16S ribosomal ribonucleic acid (rRNA) gene sequencing, high-performance liquid chromatography-mass spectrometry (LC-MS), and RNA-sequencing (RNA-seq) analysis. Result: QCLG improved weight loss, cognitive impairment, neurological function scores, blood ammonia, and brain gene expression of interleukin-6 (TNF-α), Interleukin-1ß (IL-1ß), and interleukin-6 (IL-6) induced by HE. Moreover, QCLG increased the levels of liver function indicators, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and serum TNF-α, IL-1ß, and IL-6. 16S RNA sequencing revealed increased Oscillibacter, Colidextribacter, and Helicobacter in TAA-induced mouse fecal samples. Also, the abundance of Bifidobacterium decreases TAA-induced mouse fecal samples. In contrast, QCLG treatment significantly restored the gut microbial community. Metabolomics indicated significant differences in some metabolites among the normal control, treatment, and model groups, including 5-methoxytryptophan, Daidzein, Stercobilin, and Plumieride (PLU). Conclusion: QCLG can alleviate neuroinflammation and prevent HE caused by liver injury by regulating intestinal flora in mouse models.

(3) There exists a strong positive correlation between qi stagnation and qi deficiency; (4) a moderate positive correlation is present between depression and both qi stagnation and qi deficiency among college students. All these results support the mechanism by which qi stagnation and qi deficiency contribute to depression in traditional Chinese medicine theory. Conclusion: Qi stagnation and qi deficiency are moderately associated with depression levels in college students. It is feasible to use traditional Chinese physical therapy for qi regulation to alleviate depressive symptoms among college students.

Effects of Weizhuan'an on rats with precancerous lesions of gastric cancer based on regulating gastric mucosal microflora and inflammatory factors.

Objectives: This study aimed to observe the intervention of Weizhuan'an prescription on rats with precancerous lesions of gastric cancer (PLGC) as well as its regulation on gastric mucosal microflora and inflammatory factors and explore the pharmacodynamic mechanisms of Weizhuan'an Formula. Methods: The rats were classified into the blank control group (BCG); low-, medium-, and high-dose groups of Weizhuan'an prescription (LDG, MDG, and HDG, respectively); and natural recovery group (NRG) at random. The rats in the traditional Chinese medicine (TCM) group were given corresponding doses of Weizhuan'an formula, while the rats in the NRG and BCG were given an equivalent volume of distilled water for 12 weeks. After that, gastric mucosa samples of rats were collected to observe the general and pathological changes in the gastric mucosa; the changes in gastric mucosal microflora were detected by 16S rDNA amplicon sequencing, and the inflammatory factors were analyzed by cytokine antibody microarray and Western blotting. Results: The results suggest that compared with the BCG, the pathology of gastric mucosa and gastric mucosal microflora and inflammatory factors in rats with PLGC have changed significantly, while Weizhuan'an formula effectively improved them, especially in the MDG and HDG (p < 0.05). Compared with the NRG, the abundance of probiotics such as Lactobacillus and Veillonella were increased, while the abundance of pathogens such as Proteobacteria and Pseudomonas was decreased (p < 0.05, p < 0.01), and the relative contents of IL-2, IL-4, IL-13, and MCP-1 in gastric mucosa were decreased (p < 0.05). Moreover, it can upregulate the DNA-binding transcriptional regulator, ABC type multidrug transport system, and related enzymes and affect the signaling pathways such as viral protein interaction with cytokine and cytokine receptor and T cell receptor signaling pathway significantly (p < 0.05, p < 0.01), which can promote drug absorption and utilization and repair damaged gastric mucosa. Conclusion: The study confirmed that Weizhuan'an prescription can treat rats with PLGC by regulating gastric mucosal microflora and inflammatory factors.

Chinese Herbal Compound Xiaoliu Pingyi Recipe Inhibits the Growth of Lung Adenocarcinoma by Regulating the Tumor Vascular Microenvironment.

BACKGROUND: The traditional Chinese medicine (TCM) Xiaoliu Pingyi recipe (XLPYR) has been clinically used for several decades, demonstrating favorable therapeutic effects. However, the underlying regulatory mechanisms remain unclear. The aim of this study was to explore the anti-tumor effects of XLPYR and its regulatory role in the vascular microenvironment through in vivo and in vitro experiment. MATERIALS AND METHODS: In the in vivo study, a C57BL/6J mouse model of lung adenocarcinoma (LUAD) allografts was established, and various interventions were administered for 14 days (Model group: administered normal saline via oral gavage; Pemetrexed (PEM) group: intraperitoneally injected with a solution of pemetrexed, once every 3d; XLPYR group: administered XLPYR via oral gavage; Combination (COMBI) group: received XLPYR via oral gavage simultaneously with intraperitoneal injection of pemetrexed solution). Tumor volume and weight were then compared among the groups. The impact of XLPYR on the tumor vascular microenvironment was assessed using immunohistochemistry staining. In the in vitro study, XLPYR-containing serum was prepared by oral administration to SD rats. The CCK-8 assay evaluated the effect of the serum on the proliferation of normal lung epithelial BEAS-2B cells and LUAD A549 cells, determining the optimal intervention concentrations. The cell migration and invasion abilities were evaluated using the wound-healing assay and Transwell assay, respectively. Finally, ELISA assay measured VEGF secretion levels in the LUAD cell supernatant, and RT-qPCR and Western Blot were employed to detect differences in HIF-1α, VEGFA, Ang-2, and PI3K/Akt mRNA and protein expression levels in both in vivo and in vitro experiments. RESULTS: In the in vivo study, XLPYR significantly inhibited the growth of mice LUAD allografts, with enhanced anti-tumor effects observed with prolonged drug intervention. Immunohistochemistry staining revealed reduced MVD and increased pericyte coverage in all intervention groups. Regarding vascular function, FITC-Dextran extravasation in the tumor tissues of the Model group was significantly higher than in the intervention groups, particularly with lower extravasation in the COMBI group compared to the PEM group. In the in vitro study, XLPYR demonstrated a time- and concentration-dependent inhibitory effect on LUAD cells, and with greater sensitivity in inhibiting LUAD cells compared to BEAS-2B cells. The wound-healing assay and Transwell assay confirmed that XLPYR significantly suppressed the migration and invasion abilities of LUAD cells. ELISA experiments further revealed a significant decrease in VEGF expression in the supernatant of each intervention group. RT-qPCR and Western Blot results showed consistent findings between the in vivo and in vitro experiments. HIF-1α, VEGFA, and Ang-2 mRNA and protein expression levels were significantly downregulated in the PEM group, XLPYR group, and COMBI group. There were no significant differences in the expression of PI3K and Akt mRNA and total protein, but the expression levels of phosphorylated p-PI3K and p-Akt were notably downregulated. CONCLUSION: XLPYR significantly inhibited C57BL/6J mouse LUAD allograft growth and improved the vascular microenvironment, thereby intervening in tumor angiogenesis and inducing vascular normalization. It suppressed LUAD cell proliferation, migration, and invasion, while reducing VEGF concentration in the cell supernatant. The regulatory mechanism may involve inhibiting PI3K/Akt protein phosphorylation and downregulating angiogenesis-related factors, such as HIF-1α, VEGF, and Ang-2.

Results: The findings from both traditional and network meta-analyses reveal that the combination of JiangZhiHuoXue pills (JZHX) + Conventional Western Medicine (CWM) significantly reduces FBG levels. Similarly, the AnShenNingXin capsules (ASNX) + CWM combination markedly lowers TG levels, while the FuFangQiMa capsules (FFQM) + CWM combination shows enhanced efficacy in elevating HDL levels. Notably, the combination of KangNing capsules (KNJN) + CWM demonstrates a more pronounced clinical effect compared to CWM/placebo alone. Conclusions: The study concludes that the synergistic combination of TCM and Western medicine exhibits superior therapeutic benefits in treating MetS compared to CWM/Placebo treatments alone. The combinations of JZHX, AXNX, FFQM, and KNJN with CWM emerge as potentially effective treatments.

Integrated network pharmacology and metabolomics to study the potential mechanism of Jiawei Yinchenhao decoction in chronic hepatitis B.

Chronic hepatitis B infection (CHB) is a major risk factor for the development of hepatocellular carcinoma (HCC) globally and continues to pose a significant global health challenge. Jiawei Yinchenhao decoction (JWYCH) is a modified version of Yinchenhao decoction (YCHD), which is widely used to treat liver diseases including icteric hepatitis, cholelithiasis, and hepatic ascites. However, the effectiveness and underlying mechanism of JWYCH on CHB are still unclear. This study aimed to investigate the impact of JWYCH on CHB and explore the underlying mechanism via network pharmacology and metabolomics. C57BL/6 mice were administered rAAV-HBV1.3 via hydrodynamic injection (HDI) to establish the CHB model. The infected mice were orally administered JWYCH for 4 weeks. HBsAg, HBeAg, HBV DNA, the serum liver function index, and histopathology were detected. In addition, network pharmacology was used to investigate potential targets, whereas untargeted metabolomics analysis was employed to explore the hepatic metabolic changes in JWYCH in CHB mice and identify relevant biomarkers and metabolic pathways. JWYCH was able to reduce HBeAg levels and improve liver pathological changes in mice with CHB. Additionally, metabolomics analysis indicated that JWYCH can influence 105 metabolites, including pipecolic acid, alpha-terpinene, adenosine, and L-phenylalanine, among others. Bile acid metabolism, arachidonic acid metabolism, and retinol metabolism are suggested to be potential targets of JWYCH in CHB. In conclusion, JWYCH demonstrated a hepatoprotective effect on a mouse model of CHB, suggesting a potential alternative therapeutic strategy for CHB. The effect of JWYCH is associated mainly with regulating the metabolism of bile acid, arachidonic acid, and retinol. These differentially abundant metabolites may serve as potential biomarkers and therapeutic targets for CHB.

A patient with out-of-hospital cardiac arrest saved from heart transplantation and amputation through a collaboration between modern and traditional Chinese medicine: A case report.

INTRODUCTION: Patients with end-stage heart failure have limited options for medical treatment, and this ultimately necessitates heart transplantation. Patients undergoing heart transplant surgery are burdened with substantial costs related to finances, procedural risks, and postoperative quality of life. This report presents a case of heart failure in a patient whose limbs and heart were preserved through a collaboration between modern and traditional Chinese medicine (TCM). PATIENT PRESENTATION: A 47-year-old man was admitted to the emergency department with out-of-hospital cardiac arrest (OHCA) and was diagnosed with 3-vessel disease and acute decompensated heart failure on October 27, 2020. After extracorporeal membrane oxygenation (ECMO), the patient presented with cyanosis and gangrene in all four limbs. Cardiologists and plastic surgeons recommended heart transplantation and amputation. The patient wanted to keep his limbs and heart intact and requested to receive TCM. A TCM physician was consulted by visiting staff to provide combined care. After TCM intervention, both the ejection fraction (EF) and gangrene improved. Until now, the patient continues to receive TCM treatment, lives with preserved limbs and heart, and went through SARS-CoV2 infection smoothly in 2023. CONCLUSION: TCM met the expectations of the patient and reduced the high medical expenses. This approach may improve the outlook and be a more economical option for patients with end-stage heart failure.

Comparative effectiveness and safety of four traditional Chinese medicine injections with invigorating blood circulation, equivalent effect of anticoagulation or antiplatelet in acute myocardial infarction: a Bayesian network meta-analysis.

Background: Traditional Chinese medicine injections with invigorating blood circulation (TCMI-IBCs), which have been used as antithrombosis therapies, are widely employed by Chinese clinicians as adjuvant therapy for acute myocardial infarction (AMI). Objective: A Bayesian network meta-analysis was conducted to contrast the effectiveness and safety of four TCMI-IBCs in AMI. Methods: Eight Databases were thoroughly searched before 31 December 2023, for randomized controlled trials (RCTs) focusing on the application of TCMI-IBCs combined with conventional treatments (CT) to treat AMI. All-cause mortality (ACM) was the major endpoint. Secondary outcomes included bleeding events, malignant arrhythmia (MA), recurrent myocardial infarction (RMI), left ventricular ejection fraction (LVEF), and adverse events. Stata17.0 and GeMTC software were employed for Bayesian network meta-analysis. Results: A total of 73 eligible RCTs involving 7,504 patients were enrolled. Puerarin injection (PI), Danhong injection (DI), sodium Tanshinone IIA Sulfonate injection (STSI), and Danshen Chuanxiongqin injection (DCI) combined with CT can significantly reduce the occurrence of ACM and improve LVEF in AMI (P < 0.05), while without significant impact on bleeding events or MA (P > 0.05). STSI + CT would be the optimal treatment strategy in lowering RMI and ACM. DI + CT was the most likely to be the optimal strategy in reducing MA occurrence and improving LVEF. CT was likely the most effective strategy in reducing bleeding events. However, DI + CT exhibited the least favorable safety. Conclusion: TCMI-IBCs + CT had potential benefits in the treatment of AMI. STSI + CT showed the most favorable performance in treating AMI, followed by DI combined with CT.

Network medicine analysis for dissecting the therapeutic mechanism of consensus TCM formulae in treating hepatocellular carcinoma with different TCM syndromes.

Introduction: Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality worldwide. Traditional Chinese Medicine (TCM) is widely utilized as an adjunct therapy, improving patient survival and quality of life. TCM categorizes HCC into five distinct syndromes, each treated with specific herbal formulae. However, the molecular mechanisms underlying these treatments remain unclear. Methods: We employed a network medicine approach to explore the therapeutic mechanisms of TCM in HCC. By constructing a protein-protein interaction (PPI) network, we integrated genes associated with TCM syndromes and their corresponding herbal formulae. This allowed for a quantitative analysis of the topological and functional relationships between TCM syndromes, HCC, and the specific formulae used for treatment. Results: Our findings revealed that genes related to the five TCM syndromes were closely associated with HCC-related genes within the PPI network. The gene sets corresponding to the five TCM formulae exhibited significant proximity to HCC and its related syndromes, suggesting the efficacy of TCM syndrome differentiation and treatment. Additionally, through a random walk algorithm applied to a heterogeneous network, we prioritized active herbal ingredients, with results confirmed by literature. Discussion: The identification of these key compounds underscores the potential of network medicine to unravel the complex pharmacological actions of TCM. This study provides a molecular basis for TCM's therapeutic strategies in HCC and highlights specific herbal ingredients as potential leads for drug development and precision medicine.

Traditional Chinese medicine and plant-derived natural products in regulating triglyceride metabolism: Mechanisms and therapeutic potential.

The incidence of cardiometabolic disease is increasing globally, with a trend toward younger age of onset. Among these, atherosclerotic cardiovascular disease is a leading cause of mortality worldwide. Despite the efficacy of traditional lipid-lowering drugs, such as statins, in reducing low-density lipoprotein cholesterol levels, a significant residual risk of cardiovascular events remains, which is closely related to unmet triglyceride (TG) targets. The clinical application of current TG-lowering Western medicines has certain limitations, necessitating alternative or complementary therapeutic strategies. Traditional Chinese medicine (TCM) and plant-derived natural products, known for their safety owing to their natural origins and diverse biological activities, offer promising avenues for TG regulation with potentially fewer side effects. This review systematically summarises the mechanisms of TG metabolism and subsequently reviews the regulatory effects of TCM and plant-derived natural products on TG metabolism, including the inhibition of TG synthesis (via endogenous and exogenous pathways), promotion of TG catabolism, regulation of fatty acid absorption and transport, enhancement of lipophagy, modulation of the gut microbiota, and other mechanisms. In conclusion, through a comprehensive analysis of recent studies, this review consolidates the multifaceted regulatory roles of TCM and plant-derived natural products in TG metabolism and elucidates their potential as safer, multi-target therapeutic agents in managing hypertriglyceridemia and mitigating cardiovascular risk, thereby providing a basis for new drug development.

Molecular mechanism of regulating tat protein expression of pingganjiedu TCM in the treatment of AIDS based on network pharmacology.

AIDS is a serious disease with impaired immune function caused by human immunodeficiency virus (HIV) infection. The treatment of AIDS has always been the focus of global scientific research, and Tat protein is a key regulatory protein in the process of HIV infection. Its high expression is closely related to virus replication, disease progression, etc. The aim of this study is to explore the molecular mechanism of regulating Tat protein expression by using network pharmacology based traditional Chinese medicine for calming the liver and detoxifying. 129 AIDS patients were enrolled in the study and randomly divided into HAART combined with PGJDP treatment and HAART alone treatment groups. The virological response rate, immunological response status (CD4 + T cell level, CD4/CD8) and incidence of abnormal liver function were observed before and 48 weeks after treatment. Using the TCMSP database to obtain the chemical components and targets of the main traditional Chinese medicine components in PGJDP, clinical results indicate that the combination of HAART and PGJDP treatment can improve the virological response rate (P > 0.05); Increase the number of CD4 + T lymphocytes (P > 0.05); Significantly increased CD4/CD8 ratio (P < 0.01); Simultaneously, it significantly reduced the incidence of liver dysfunction (P < 0.01). After screening and analysis, the Chinese herbal medicine for calming liver and detoxifying has the potential to significantly regulate the expression of Tat protein. These Chinese herbal compounds can reduce the expression of Tat protein by affecting key pathways and regulating the expression of related genes, which has potential therapeutic effects on the treatment of AIDS.

Potential mechanism of Luoshi Neiyi prescription in endometriosis based on serum pharmacochemistry and network pharmacology.

Introduction: Endometriosis (EMs) is characterized by ectopic growth of active endometrial tissue outside the uterus. The Luoshi Neiyi prescription (LSNYP) has been extensively used for treating EMs in China. However, data on the active chemical components of LSNYP are insufficient, and its pharmacological mechanism in EMs treatment remains unclear. This study aimed to explore the potential mechanism of LSNYP for EMs through network pharmacology based on the components absorbed into the blood. Methods: Ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry was used to analyze blood components, and a series of network pharmacology strategies were utilized to predict targets of these components and EMs. Protein-protein interaction (PPI) network analysis, component-target-disease network construction, gene ontology (GO) functional enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. Additionally, molecular docking, molecular dynamics simulations, and in vitro and in vivo experiments were conducted to validate the HIF1A/EZH2/ANTXR2 pathway associated with hypoxic pathology in EMs. Results: Thirty-four absorbed components suitable for network pharmacology analysis were identified, and core targets, such as interleukin 6, EGFR, HIF1A, and EZH2, were founded. Enrichment results indicated that treatment of EMs with LSNYP may involve the regulation of hypoxia and inflammatory-related signaling pathways and response to oxidative stress and transcription factor activity. Experimental results demonstrated that LSNYP could decrease the expression of HIF1A, ANTXR2, YAP1, CD44, and ß-catenin, and increased EZH2 expression in ectopic endometrial stromal cells and endometriotic tissues. Molecular docking and molecular dynamics simulations manifested that there was stable combinatorial activity between core components and key targets of the HIF1A/EZH2/ANTXR2 pathway. Conclusion: LSNYP may exert pharmacological effects on EMs via the HIF1A/EZH2/ANTXR2 pathway; hence, it is a natural herb-related therapy for EMs.

Integrating transcriptomics and metabolomics to reveal the protective effect and mechanism of Bushen Kangshuai Granules on the elderly people.

Background: Aging is characterized by a decline in the adaptability and resistance of the body. In this study, Bushen Kangshuai Granules (BKG), as a kind of Chinese herbal formula, was developed and shown to alleviate aging-related symptoms. Methods: Self-controlled study combined with RNA-seq and metabonomics were used to expound the efficacy and safety of BKG and revealed the regulation mechanism of BKG treating aging. In vitro experiments were used to confirm the analytical results. The aging cell model of AC16 cells were treated with D-galactose. The RT-qPCR was used to detect the impact of BKG on telomere length. The DCFH-DA staining was used for detecting intracellular ROS. The targeted signaling pathway was selected and verified using Western blot. Results: After 8 weeks of treatment, BKG significantly reduced SOD level (p = 0.046), TCM aging symptoms (p < 0.001) and TNF-α level (p = 0.044) in the elderly participants. High-throughput sequencing showed that BKG reversed the expression of 70 and 79 age-related genes and metabolites, respectively. Further enrichment analysis indicated that BKG downregulated the PI3K-AKT signaling pathway, extracellular matrix (ECM)-receptor interaction, and Rap1 signaling pathway, while up-regulating sphingolipid metabolism. The results of in vitro experiments show that, after D-gal treatment, the viability and telomere length of AC16 cells significantly decreased (p < 0.05), while the expression of ROS increased (p < 0.05), BKG significantly increased the telomere length of AC16 cells and reduced the level of ROS expression (p < 0.05). In addition, BKG decreased the expression of THBS1, PDGFRA, and EPS8L1(p < 0.05), consistent with the RNA-seq results. Our results also showed that BKG affects PI3K-AKT signaling pathway. Conclusion: BKG can significantly improve aging-related symptoms and increase SOD levels, which may be associated with the reversal of the expression of various aging-related genes. The PI3K-AKT signaling pathway and sphingolipid metabolism may be potential mechanisms underlying BKG anti-aging effects.

Natural redox mediator anthraquinone aloe-emodin facilitated the in-situ mineralized γ-FeO(OH) membrane for the removal of tannic acid through photocatalytic-PMS activation.

The growing utilization of Traditional Chinese Medicine (TCM) has resulted in an increase in wastewater. Herein, a new kind of organic-inorganic redox mediator membrane by immobilizing γ-FeO(OH) and aloe-emodin(AE) with the characteristic large π-conjugation anthraquinone structure on PVDF membrane was innovatively achieved. AE exhibiting both electron deficiency and redox activity possesses a co-catalyst role in degradation of tannic acid (TA), aiding in the separation of charge carriers through the sequential hydrogenation and dehydrogenation of AE. The removal rates of TA were 92.8 % in the tannic acid solution and 60.3 % in the simulated rhubarb wastewater by the AE-γ-FeO(OH) membrane under PMS+Vis conditions in 45 min. Also, they show a higher recovery of pure water flux and owning good fouling performance. Overall, this current work presents a novel approach for the design and preparation of organic-inorganic photocatalytic composite membrane using readily available natural products for the purification TCM wastewater.

Jingzhi Niuhuangjiedu Tablet Ameliorates Oral Mucositis via the AKT/NFκB/NLRP3 Signaling Pathway: A Network Pharmacology and Experimental Validation.

BACKGROUND: Oral Mucositis (OM) is a common and highly symptomatic complication of cancer therapy that affects patient function and quality of life. Jingzhi Niuhuangjiedu Tablet (JNT) is derived from the famous Chinese herbal formulas Huanglian Jiedu and Fangfeng Tongsheng decoctions, which have been widely used to treat heat toxin syndrome diseases, such as acute pharyngitis, periodontitis, oral ulcers, and oral mucositis (OM), but the underlying mechanism remains unclear. OBJECTIVES: This study validated the efficacy and explored the potential mechanisms of JNT in the treatment of OM by integrating network pharmacological analyses and experimental verification. METHODS: Network pharmacology and molecular docking techniques were used to predict the active components, key targets, and potential mechanisms of action of JNT against OM. The rat OM model was established by administering 5-Fluorouracil (5-FU) and acetic acid to the rat oral mucosa. Lipopolysaccharide (LPS)-treated human gingival fibroblasts (HGFs) were used as an inflammatory cell model. The GFP-NFκB HEK293T cell line was transfected to evaluate the anti-NFκB activity of JNT. RESULTS: A total of 236 Chinese herbal components and 201 corresponding targets were predicted for OM treatment using JNT. Bicuculine, luteolin, wogonin, and naringenin were identified as the important active compounds, while AKT1, ALB, IL6, MAPK3, and VEGFA were considered to be the major targets. Molecular docking revealed that these active compounds exhibited strong binding interactions with their targets. In vivo and in vitro experiments demonstrated that the anti-OM effect of JNT might be closely related to AKT1, NFκB, caspase-1, and NLRP3, as well as biological processes, such as inflammatory response and oxidative stress. CONCLUSION: Network pharmacological and experimental evidence indicates that JNT has a potential therapeutic effect on OM by regulating the Akt/NFκB/NLRP3 pathway.
