The roots of Baphicacanthus cusia (Nees) Bremek, commonly known as Nan-Ban-Lan-Gen, have been used for a long time in traditional Chinese medicine to manage inflammatory and infectious diseases. However, the structural features and bioactive potential of its polysaccharides have not been extensively studied. In the present study, a novel homogeneous polysaccharide (BcP-b2) was isolated from the roots of B. cusia, and its bioactivity was evaluated using an activity-guided purification strategy. Multi-dimensional structural analysis identified BcP-b2 as a highly branched galactoarabinan with a molecular weight of ~38.1 kDa, featuring a well-defined backbone and a variety of side chains. In vitro and in vivo assays demonstrated that BcP-b2 attenuated the accumulation of reactive oxygen species (ROS) and enhanced the activities of endogenous antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px). Additionally, BcP-b2 activated macrophages under basal conditions and alleviated lipopolysaccharide (LPS)-induced cytotoxicity and inflammatory mediator release. Transcriptomic and Western blot analyses revealed that these dual effects were achieved through the simultaneous suppression of the PI3K/Akt inflammatory axis and activation of the Nrf2/HO-1 antioxidant pathway, concomitant with enhanced nuclear translocation of Nrf2. These findings provide a molecular basis for the ethno-pharmacological use of Nan-Ban-Lan-Gen and identify BcP-b2 as a promising candidate for further investigation as a potential therapeutic agent.

Baikal skullcap (Scutellaria baicalensis) is one of the most important herbs used for centuries in traditional Chinese medicine. The main objective of the research was to micropropagate and introduce the most vigorous lines into garden cultivation. Eleven lines representing individual genotypes were selected and propagated using nodal segments. 6-Benzylaminopurine (BAP) at 1.0 mg L⁻¹, alone or with indole-3-acetic acid (IAA) at 0.1 mg L⁻¹, was the most effective for shoot regeneration. Significant variability in multiplication rate (2.5–6.4 shoots per explant) was observed among the lines. Shoots were successfully rooted (97.9%) and then acclimatized. After six months of cultivation, 113 well-developed plants representing all genotypes were obtained. Depending on the genotype, the final survival rates ranged from 26.9 to 80.0%. Flow cytometry (FCM-DAPI) analysis confirmed the ploidy stability of the micropropagated plants and ISSR markers revealed notable variability among the lines. Moreover, a polymorphism level of 36.4% was detected within line SB_6, whereas the other two analyzed lines (SB_3 and SB_7) maintained in vitro for four years showed no somaclonal variation. Therefore, genetic stability must be monitored, particularly in long-term cultures. In subsequent studies, the acclimatized lines will be evaluated for root yield and phytochemical content under garden conditions. Full article

Exercise-induced fatigue is a common phenomenon after intense exercise or labor, which significantly affects an individual’s exercise performance and physical and mental health. Its timely recovery is crucial for enhancing exercise capacity and preventing injuries. Acupuncture, as a “simple, convenient, inexpensive, and effective” non-pharmaceutical therapy in traditional Chinese medicine, has shown potential unique advantages in the prevention and treatment of exercise-induced fatigue. This narrative review summarizes the recent research progress, with core mechanisms including the inhibition of oxidative stress and inflammation, regulation of energy metabolism, and improvement of central nervous system function, which are mainly verified by preclinical animal studies and partially supported by small-sample clinical trials. The application effects are reflected in the fact that pre-acupuncture before fatigue can enhance anti-fatigue reserves, and post-fatigue treatment can alleviate symptoms and promote recovery, with human evidence limited to small-scale clinical observations. In conclusion, acupuncture has potential therapeutic effects on the prevention and treatment of exercise-induced fatigue, providing a theoretical and practical reference for clinical application.

The influenza A virus (IAV) has been responsible for multiple seasonal epidemics and poses a pandemic threat, and the growing number of variant strains constitutes a persistent threat to humanity. This study aimed to identify anti-influenza compounds from a traditional Chinese medicine (TCM) monomer library using a machine learning approach, with calmodulin as a hypothesis-driven target. The antiviral efficacy of the compounds with the highest predicted binding scores from virtual screening was evaluated using integrated computational and experimental approaches. A pre-trained protein language model (ConPLex) was employed for virtual screening. Molecular docking was used to predict binding characteristics, and network pharmacology was applied to generate hypotheses on multi-target mechanisms. The cytotoxicity and anti-H1N1 activity of the selected compounds were assessed in vitro, followed by in vivo evaluation of survival, lung pathology, viral load, and inflammatory mediators in a lethal mouse infection model. Sodium deoxycholate (NaDC) and deoxycholic acid (DCA) were identified as promising lead compounds. Both exhibited dose-dependent inhibition of viral replication in vitro with low cytotoxicity. Treatment with NaDC and DCA significantly improved survival rates and reduced lung pathology in H1N1-infected mice. Treatment was associated with suppression of nuclear factor kappa-B (NF-κB) activation, reduced pro-inflammatory cytokines, and elevated interleukin-10 (IL-10) levels. Molecular docking predictions indicated that NaDC and DCA exhibit moderate binding affinity for calmodulin, with binding energies of −8.38 kcal/mol and −7.61 kcal/mol, respectively. Furthermore, network pharmacology analysis suggested that these compounds may modulate pathways related to viral infection, inflammation, and immune regulation. NaDC and DCA demonstrate anti-influenza activity both in vitro and in vivo, reducing viral replication and alleviating inflammatory lung injury. These findings position NaDC and DCA as promising lead compounds for anti-influenza drug development and provide a foundation for further mechanistic validation. Full article

Background: Diabetic retinopathy (DR) is one of the major complications of diabetes mellitus. EJPs (Erjing Pills) are believed in Traditional Chinese Medicine to have the effects of a nourishing essence and a brightening of the eyes, but the specific effect on DR remains unclear. This study aims to investigate the therapeutic effects and underlying mechanisms of EJPs on DR. Methods: The chemical profile of EJPs was characterized by UHPLC-MS. Network pharmacology and molecular docking were employed to predict its active ingredients and potential targets. A DR rat model was induced by streptozotocin. Retinal morphology and function were assessed by OCT, FFA, and H&E staining. The expressions of proteins and mRNAs related to the AGE-RAGE pathway, oxidative stress, inflammation, and tight junctions were detected by Western blot, qPCR, and ELISA. Results: LC-MS and network pharmacology analysis identified 638 common targets between EJPs and DR, with core targets including SRC, AKT1, and MAPK1, primarily enriched in the AGE-RAGE signaling pathway. Molecular docking confirmed strong binding (binding energy < −5.0 kcal/mol) between key EJP constituents and core targets. In vivo, EJP treatment significantly alleviated retinal vascular leakage, improved retinal thickness, and alleviated histopathological damage. In addition, EJPs downregulated the AGEs-RAGE/NF-κB axis and pro-inflammatory cytokines while enhancing antioxidant defenses and tight junction proteins in the retinas of DR rats. Conclusions: EJPs ameliorate DR by protecting the blood–retinal barrier and modulating the AGE-RAGE/oxidative stress/inflammation network, demonstrating a multi-component, multi-target, and multi-pathway mechanism. This study provides a mechanistic basis for the potential application of EJPs in DR management. Full article

Rheumatoid arthritis (RA) remains a recalcitrant clinical challenge, as modern therapies are often hampered by adverse effects, suboptimal responses, and failure to achieve radical cure. Traditional Chinese Medicine (TCM) and Tujia ethnomedicine, with centuries of accumulated experience in managing RA (classified as “Bi Syndrome” in TCM), offer distinct theoretical frameworks and abundant therapeutic resources. TCM emphasizes syndrome differentiation-based holistic regulation, while Tujia ethnomedicine relies on indigenous medicinal plants and empirically derived therapies shaped by its unique geographical context. This review aims to accelerate the integration of traditional wisdom with contemporary pharmacology for the development of novel RA therapies. A comprehensive literature search was performed across PubMed, Web of Science, CNKI, and ethnomedical monographs to synthesize data on their theoretical underpinnings, therapeutic strategies, mechanisms of action, and clinical efficacy. TCM and Tujia ethnomedicine possess significant anti-RA effects, characterized by multi-component, multi-target synergistic mechanisms that complement modern medicine. However, they face common challenges including unclear material bases of active components, insufficient standardized clinical evidence, and inadequate quality control protocols. This review provides a critical foundation for integrating TCM/Tujia ethnomedicine with modern pharmacology, highlighting the urgent need for further research to clarify active constituents, establish standardized protocols, and validate clinical efficacy—ultimately facilitating the development of safer, more effective RA therapies.

Pseudomonas aeruginosa, an opportunistic pathogen, is a major threat to hospital infection control and global public health due to its strong environmental adaptability, complex virulence systems, efficient biofilm formation capability, and widespread multidrug resistance. Traditional single-target antibiotics are often inadequate for clinical treatment. The research into Plant-Derived Bioactive Compounds for combating P. aeruginosa infections is reviewed, highlighting their advantages (many of which are extensively studied in Traditional Chinese Medicine) over conventional antibiotics. The antimicrobial mechanisms of these compounds include the inhibition of bacterial quorum sensing (QS) systems to suppress virulence factor expression rather than direct anti-bactericidal effects, delaying the development of resistance. The abundant natural medicinal plants and their diverse chemical structures provide ample material for active compound screening to identify unique chemical compositions with specific binding to pathogen targets. Plant-Derived Bioactive Compounds exhibit excellent safety profiles, targeting bacterial-specific pathways or host immune regulation, resulting in minimal off-target toxicity. Plant-Derived Bioactive Compounds exert anti-P. aeruginosa effects via inhibition of QS systems to reduce pathogenicity by disrupting intercellular signaling, suppressing biofilm formation/maturity to overcome biofilm-associated resistance, directly interacting with bacterial structure. Plant-Derived Bioactive Compounds are promising treatments for drug-resistant P. aeruginosa infections, providing lead compounds for novel anti-infective drug development. Full article

Background/Objectives: San-Huang-Xie-Xin-Tang (SHXXT) is a classical traditional Chinese herbal formula composed of Coptis chinensis, Scutellaria baicalensis, and Rheum palmatum, with documented anti-inflammatory and anticancer properties. Despite growing interest in its pharmacological potential, systematic evaluation of its gene regulatory effects across multiple cancer types remains limited. This study aimed to assess the prognostic relevance of SHXXT-regulated genes across pan-cancer contexts using publicly available transcriptomic and clinical datasets. Methods: Fifteen active compounds of SHXXT were identified from traditional Chinese medicine databases (Encyclopaedia of Traditional Chinese Medicine (ETCM) 2.0, Chinese Compound Medicine Database (ccTCM), and Integrated Traditional Chinese Medicine Database (ITCM)). Compound-induced gene expression profiles were obtained from MCF7-based transcriptomic perturbation data in the ITCM database and integrated with The Cancer Genome Atlas (TCGA) across 24 cancer types. Survival-associated genes were evaluated using Cox proportional hazards regression and Kaplan–Meier analysis. A weighted prognostic scoring framework, supported by normalization and sensitivity analyses, was developed to prioritize cancer types according to the concordance between SHXXT-induced gene regulation and favorable prognostic patterns. Functional enrichment analysis was performed using Annotation, Visualization, and Integrated Discovery (DAVID), and cancer-related genes were annotated using the OncoKB database. Complementary in vitro studies, including Annexin V/propidium iodide (PI) and MT-1 staining assays, were conducted in Hep3B cells using a Good Manufacturing Practice (GMP)-certified commercial SHXXT preparation. Results: SHXXT-regulated genes were significantly enriched in cancer-related pathways, particularly the PI3K–Akt and MAPK signaling pathways. Pan-cancer analysis revealed substantial heterogeneity in prognostic alignment across cancer types. Among the 24 cancer cohorts analyzed, kidney renal clear cell carcinoma (KIRC) achieved the highest prognostic alignment score within the proposed framework. In KIRC, several genes, including PIK3CA, PIK3CB, KRAS, and RAF1, remained significantly associated with favorable prognostic alignment after multivariable adjustment. Pathway enrichment analysis further identified PI3K–Akt and MAPK signaling as the most significantly represented pathways among favorably aligned genes. In contrast, hepatocellular carcinoma exhibited a relatively low prognostic alignment score, consistent with in vitro observations indicating predominantly non-selective cytotoxic stress rather than cancer-specific therapeutic activity. Conclusions: SHXXT-regulated genes exhibited marked heterogeneity across cancer types, with KIRC was consistently prioritized as the top-ranked cancer type across multiple analytical scenarios, suggesting a strong concordance between SHXXT-associated gene regulation and favorable prognostic signatures. These findings represent computational predictions derived from transcriptomic and survival associations rather than direct evidence of therapeutic efficacy. The study provides a reproducible pan-cancer strategy for prioritizing candidate cancer types for future mechanistic and experimental validation of traditional Chinese medicine formulations.

Smilacis Glabrae Rhizoma is a traditional Chinese medicine commonly used for hyperuricemia. Engeletin, one of its major flavonoids, exhibits various pharmacological activities, but its in vivo uric acid-lowering activity and metabolic processes remain unclear. This study aims to elucidate the in vivo existence forms of engeletin and the pharmacological basis underlying its uric acid-lowering effects. The in vivo metabolites of engeletin were identified by using UHPLC-Q-TOF-MS. The xanthine oxidase inhibitory activity was investigated using in vitro enzymatic assays. The in vivo uric acid-lowering effect was evaluated in hyperuricemic mice. A total of 11, 34, 7, 6, and 5 compounds were detected in urine, feces, serum, liver, and kidney samples, respectively. After removing duplicates, 52 compounds were preliminarily identified as in vivo existence forms of engeletin. The main metabolic reaction types were glucuronidation, sulfation, and hydrolysis. Engeletin exhibited no xanthine oxidase inhibitory activity in vitro but possessed uric acid-lowering activity in vivo. Neoisoastilbin and naringenin were metabolites with both xanthine oxidase inhibitory activity and uric acid-lowering activity. The in vivo uric acid-lowering activity of engeletin may be attributable to its two metabolites rather than itself. This study elucidated the pharmacological basis of engeletin and laid the foundation for developing potential therapeutics for hyperuricemia. Full article

Alzheimer’s disease (AD) is characterized by Tau hyperphosphorylation, β-amyloid (Aβ) accumulation, and progressive neuronal loss. Gastrodia elata (G. elata), a traditional Chinese medicine with well-established neuroprotective properties, was investigated. Two G. elata-derived miRNAs, Gas-miR04-3p and Gas-miR19-5p, were identified as regulators of JNK3. By means of Western blot, RT-qPCR, and assessments of antioxidant indices, it was demonstrated that Gas-miR04-3p and Gas-miR19-5p can suppress JNK3 expression, reduce Tau phosphorylation at Ser202 and Ser396, enhance antioxidant capacity, and attenuate apoptosis in AD-related cellular and molecular pathology models. These miRNAs were also detectable in murine brain tissues following oral administration of total RNA extracted from G. elata. Their administration was associated with decreased JNK3 activation, alleviated Tau hyperphosphorylation, and improved expression of apoptosis-related proteins in AD mouse models. These results suggest that G. elata miRNAs may exert neuroprotective effects through regulation of JNK3 signaling, thereby attenuating Tau-related pathological changes and neuronal injury in AD-related models.

Background: Symbiotic fungi play essential roles throughout the entire cycle of orchid plants, including seed germination, seedling development, and maturation. Dendrobium officinale Kimura & Migo (Orchidaceae) (D. officinale) is a rare and highly valued traditional Chinese medicinal herb. Currently, artificial breeding using tissue culture technology is widely adopted and essential in the Dendrobium industry; however, this approach may impair or disrupt the plant’s ability to establish and maintain symbiotic relationships with mycorrhizal fungi. Methods: In this study, the fungal endophyte community (FEC) in the roots of D. officinale cultivated under four different modes was analyzed using high-throughput sequencing. Correlation analyses were also carried out to examine the relationships between bioactive compounds and the FEC. Results: (1) The FEC in D. officinale roots was dominated by Ascomycota and Basidiomycota, with significant differences in abundance, diversity, and community structure among cultivation modes; (2) the FEC under greenhouse cultivation differed significantly from those under tree epiphytic cultivation in terms of fungal nutritional types and dominant taxa; (3) six major mycorrhizal fungal taxa were identified in Dendrobium roots, although non-mycorrhizal fungi accounted for approximately 97% of the community; and (4) polysaccharide content in Dendrobium stems was positively correlated with certain root fugal endophytes (Exophiala, alaromyces, Pseudodactylaria, and Fellomyces). Conclusions: This study provides a foundation for understating the growth of D. officinale under different cultivation modes and highlights the relationship between bioactive compound accumulation and fungal endophyte communities.

Astragalus membranaceus, a medicinal plant used in traditional Chinese medicine for centuries, has attracted growing scientific attention for its potential anti-aging and anticancer properties, particularly for skin and bone health. Its key bioactive compounds like astragalosides, cycloastragenol, and its commercial derivative TA-65, have been associated with telomerase activation and telomere maintenance, suggesting a possible role in modulating cellular senescence and tissue repair processes. In addition to the claimed telomere maintenance, A. membranaceus exhibits antioxidant, anti-inflammatory, and DNA-protective activities, properties that contribute to its anti-aging effects. Emerging evidence also suggests that telomerase modulation by A. membranaceus influences cancer cell dynamics, either suppressing tumor progression through immune regulation and apoptosis induction or, in some contexts, potentially promoting tumor growth. This duality highlights the importance of dose, formulation, and targeted application. Clinically, TA-65 has been reported to improve vascular health, bone mineral density, and skin elasticity in aging individuals. Preclinical studies further support its protective effects against osteoporotic bone loss and photoaging-induced dermal degeneration. This review summarizes the phytochemical composition of A. membranaceus and critically evaluates the mechanistic and therapeutic evidence underlying its anti-aging and anticancer actions on skin and bone tissues. It also discusses the pharmacokinetic properties of A. membranaceus, including its absorption, bioavailability, and safety profile. The integration of A. membranaceus into evidence-based senile therapeutic strategies holds promise, but further mechanistic and clinical studies are required to optimize its safety and efficacy.

Deep eutectic solvent (DES) extraction is a green and efficient technology. As a substitute for organic reagents, DESs are widely used to extract active ingredients from traditional Chinese medicine. This study established an environmentally friendly and efficient method for extracting astaxanthin (AST) from Phaffia rhodozyma (PR) using ultrasound-assisted deep eutectic solvents (DESs-UAE). The astaxanthin content was determined by high-performance liquid chromatography (HPLC). Six types of deep eutectic solvents composed of DL-menthol and selected hydrogen bond donors were prepared and evaluated, among which the DL-menthol–acetic acid system showed superior extraction performance. Response surface methodology (RSM) was employed to optimize extraction parameters (ultrasonic power, time, and temperature), and the optimal conditions were determined as follows: ultrasonic power 420 W, ultrasonic time 20 min, and ultrasonic temperature 60 °C, achieving an AST extraction rate of 62% (2.49 mg/g). Compared with conventional organic solvent extraction, DESs exhibited a significantly higher AST extraction rate from PR, except for dimethyl sulfoxide (DMSO). Scanning electron microscopy (SEM) analysis demonstrated that DES-UAE treatment disrupted the cellular structure of PR, resulting in numerous surface pores; this facilitated the release of intracellular bioactive components and significantly improved AST extraction efficiency. The PR extract showed no significant cytotoxicity and could effectively promote L929 cell proliferation. It concentration-dependently increased superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) content in H₂O₂-induced oxidative stress L929 cells, thereby alleviating oxidative damage. Additionally, it concentration-dependently upregulated type I collagen expression in these cells, ameliorated the decline in collagen synthesis function, and exerted a protective effect against cellular oxidative damage. This study provides a green alternative to toxic solvents and offers important theoretical and chemical support for the extraction of natural products and the high-value utilization of Phaffia rhodozyma (PR). Deep eutectic solvents have emerged as promising green alternatives to hazardous organic solvents, yet hydrophobic DESs tailored for lipophilic astaxanthin extraction from Phaffia rhodozyma and the linkage between extraction performance and anti-aging bioactivity remain insufficiently explored. Here, an ultrasound-assisted hydrophobic deep eutectic solvent extraction strategy was constructed to acquire astaxanthin, aiming to overcome low efficiency and environmental risks of conventional organic extraction techniques. Six DL-menthol-based DESs were prepared and screened, and DL-menthol–acetic acid possessed the optimal extraction capacity. Key extraction parameters were optimized via response surface methodology, and the maximum astaxanthin extraction recovery reached 62% (2.49 mg/g) under 420 W ultrasonic power, 20 min treatment and 60 °C. This yield was markedly higher than that of most common organic solvents; though comparable extraction effect was obtained with DMSO, the adopted DES possessed outstanding low-toxic and biodegradable superiorities that DMSO cannot match. SEM characterization verified that the combined treatment destroyed yeast cell structure and formed porous morphology, which accelerated intracellular astaxanthin release and accounted for improved extraction efficiency. Biological assays proved the extract possessed good biosafety and proliferation-promoting effect on L929 cells. It effectively relieved cellular oxidative injury by elevating the SOD level and reducing MDA accumulation in oxidative damaged cells, and upregulated type I collagen expression to mitigate aging-related collagen loss. This work develops an eco-friendly and high-efficiency extraction route for lipophilic active substance, confirms the practical value of hydrophobic DES, and provides experimental basis for high-value utilization of Phaffia rhodozyma resources.

The purpose of this study was to use data mining and network pharmacology to determine drug patterns for bovine viral diarrhea (BVD). The frequency, properties, tastes, meridian tropism, and functions of prescription data were gathered and examined from four literature databases (2004–2024). Cluster analysis was used to find prescription patterns, and the Apriori algorithm (SPSS Modeler 18) was used to find associations. A total of 391 literature-derived prescription records were included in the analysis, involving 189 distinct herbal medicines and a cumulative herb-use frequency of 2031 occurrences. These herbs primarily enter the liver meridian and were categorized as cold, warm, or neutral. The predominant tastes were bitter, pungent, and sweet. Five frequently recorded herbs and 14 co-occurrence patterns among herbs were extracted. According to traditional Chinese medicine (TCM), spleen–stomach deficiencies and damp-heat pathogens are linked to BVD. These medication patterns were mainly associated with heat-clearing, detoxification, spleen-strengthening, and Qi-regulating strategies in TCVM theory. Targets were screened, PPI networks were constructed, and enrichment studies for core herbs (Baitouweng, Huangbo, Huangqin, Qinpi, and Zhizi) were performed using network pharmacology. The binding affinities between disease targets and active components were further assessed using molecular docking. The findings provide a descriptive summary of medication patterns and generate preliminary hypotheses regarding potential compound–target–pathway associations involved in the symptomatic and supportive use of TCM for BVD.

Aging is associated with a rising burden of chronic metabolic, cardiovascular, musculoskeletal, and neurodegenerative diseases that share interconnected pathological mechanisms, including oxidative stress, chronic inflammation, mitochondrial dysfunction, metabolic imbalance, and immune dysregulation. Because these disorders arise from complex and overlapping biological disturbances, conventional single-target therapies often provide only limited benefit. In this context, traditional Chinese herbal medicines, characterized by multi-component and multi-target actions, are being re-evaluated using modern pharmacological and systems biology approaches. Among these, Astragalus membranaceus and Cordyceps species have attracted attention as representative tonic medicines with long-standing traditional use and growing biomedical relevance. Their principal bioactive constituents, including polysaccharides, saponins, flavonoids, sterols, and nucleoside derivatives such as cordycepin, exert pleiotropic effects on inflammatory signaling, redox homeostasis, mitochondrial function, metabolic regulation, and immune responses. This review summarizes current evidence on bioactive derivatives from Astragalus and Cordyceps in aging-related chronic and neurodegenerative disorders, including diabetes, cardiovascular dysfunction, osteoarthritis, cancer, Alzheimer’s disease, and Parkinson’s disease. It focuses on mechanistic findings from cellular and animal studies and critically discusses key translational challenges, such as compositional variability, poor bioavailability, lack of standardized preparation, limited clinical validation, and safety concerns related to toxicity and herb–drug interactions.
