This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine (TCM), including spleen deficiency theory, spleen-stomach damp-heat theory, and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation, refinement of therapeutic methods, systematization of pathogenesis, and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao (焦) balance, and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research, spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier, metabolic disorders, and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism, inflammatory cytokines, and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics, thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

Microbial infections are a prevalent challenge in the prevention and treatment of oral diseases. Antibiotic therapy faces clinical limitations due to its single-target mechanism and tendency to induce resistance with repeated use, necessitating novel antibacterial strategies. Stimuli-responsive antibacterial materials, whose antimicrobial activity can be modulated by external stimuli, offer advantages such as remote controllability, potential for localized precision treatment, and a reduced risk of inducing resistance. Among these materials, mechanical force-triggered piezoelectric materials exhibit significant antibacterial activity in the biomedical field owing to their unique piezoelectric effect, excellent stability, and good biocompatibility. Research has shown that piezoelectric materials can convert mechanical energy into electrical energy in response to external forces, which enables antibacterial effects without requiring an external power source. The underlying mechanisms primarily include direct electric field effects, generation of reactive oxygen species, and immune modulation. Preliminary applications in treating oral infections (e.g., dental caries, periodontitis, and peri-implantitis) have confirmed their stability and biocompatibility, establishing a foundation for clinical translation. However, long-term efficacy and biosafety in the complex oral microenvironment require further validation. Future research should focus on optimizing material preparation protocols to enhance antibacterial efficacy and stability, further investigating the underlying antimicrobial mechanisms, and systematically evaluating their therapeutic outcomes and safety profiles across various types of oral infections. This review summarizes the antibacterial effects, mechanisms, stability, safety, and research progress of piezoelectric materials in the stomatologic field, aiming to provide new insights for further research and application in this area.

ObjectiveTo investigate the mechanism of action of modified Chaihu Shugan Powder in the treatment of abnormal gallbladder relaxation in gallbladder cholesterol stone (CS) with liver depression syndrome, and to provide a basis for clinical medication. MethodsMice were given a high-fat lithogenic diet combined with chronic unpredictable mild stress (CUMS) to establish a model of CS. A total of 45 male C57BL/6 mice were randomly divided into blank group (6 mice fed a normal diet) and CS group (39 mice fed a high-fat lithogenic diet). After CS modeling, the CS group was further randomly divided into four subgroups of CS group, CS liver depression group, traditional Chinese medicine group (treated with modified Chaihu Shugan Powder), and Western medicine group (treated with ursodeoxycholic acid), with 9 mice in each group. All subgroups were fed with the high-fat lithogenic diet, and all mice except those in the CS group were given 21 days of CUMS for modeling. Samples were collected after intervention. The serum levels of cholecystokinin (CCK), liver function parameters, and blood lipid profiles were measured; HE staining was performed for liver and gallbladder tissue; qPCR and Western blot were used to measure the mRNA and protein expression levels of G protein-coupled bile acid receptor 1 (TGR5) and glucagon-likepeptide-1/2 (GLP-1/2) in the intestine and TGR5 and glucagon-like peptide-2 receptor (GLP-2R) in gallbladder; metabolomics methods were used to determine bile acid composition in intestinal contents. The independent-samples t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test or the Games-Howell method was used for further comparison between two groups. ResultsCompared with the blank group, the CS group showed significant gallstone formation, bile turbidity, hepatic steatosis, abnormal gallbladder wall structure, and significant increases in anxiety- and depression-like behaviors based on behavioral tests; significant increases in the level of total cholesterol in bile and the serum levels of alanine aminotransferase, aspartate aminotransferase, and low-density lipoprotein and significant reductions in the level of total bile acid (TBA) in bile and the serum levels of CCK and high-density lipoprotein (HDL) (all P<0.05); significant increases in the mRNA expression levels of GLP-1/2 and TGR5 in the intestine and the protein expression levels of GLP-2R and TGR5 in the gallbladder and significant reductions in the mRNA expression levels of GLP-2R and TGR5 in the gallbladder (all P<0.05); significant changes in multiple bile acid components in intestinal contents (all P<0.05). Compared with the CS group, the CS liver depression group had further aggravation of pathological and behavioral manifestations, changes in bile acid composition, significant increases in the protein and mRNA expression levels of TGR5 and GLP-1/2 in the intestine, and significant increases in the protein and mRNA expression levels of TGR5 and GLP-2R in the gallbladder (all P<0.01). Compared with the CS liver depression group, both treatment groups had an improvement in gallbladder morphology, alleviation of stones and liver injury, and recovery of liver function and blood lipid levels, as well as significant reductions in the protein and mRNA expression levels of TGR5 and GLP-1/2 in the intestine and TGR5 and GLP-2R in the gallbladder (all P<0.05); the traditional Chinese medicine group showed significant increases in glycodeoxycholic acid (GDCA), tauro-α-muricholic acid (T-α-MCA), and taurochenodeoxycholic acid (TCDCA) (all P<0.05), while the Western medicine group showed significant increases in taurohyodeoxycholic acid, T-α-MCA, TCDCA, GDCA, and glycoursodeoxycholic acid (all P<0.05). Compared with the Western medicine group, the traditional Chinese medicine group had significantly greater behavioral improvements, significantly higher levels of TBA in bile and serum HDL (both P<0.01), significant reductions in the protein expression levels of TGR5 and GLP-1/2 in the intestine and TGR5 and GLP-2R in the gallbladder, and a significant reduction in the mRNA expression level of TGR5 in the intestine (all P<0.01), as well as a significant increase in tauroursodeoxycholic acid and significant reductions in glycoursodeoxycholic acid, taurohyodeoxycholic acid, TCDCA, and taurolithocholic acid (all P<0.05). ConclusionModified Chaihu Shugan Powder can improve liver function and abnormal gallbladder relaxation in CS with liver depression syndrome by regulating the bile acid-TGR5 axis, thereby exerting the therapeutic effect of soothing the liver, resolving depression, moving Qi, and promoting bile flow.

Hepatic fibrosis is a pathological repair response of the liver to various chronic injuries, commonly seen in chronic liver diseases such as viral hepatitis, alcoholic liver disease, non-alcoholic fatty liver disease, etc. Hepatic fibrosis is a necessary stage for the development of chronic liver disease into cirrhosis or even hepatocellular carcinoma. Reversing or delaying the progression of hepatic fibrosis is crucial for the treatment of chronic liver disease, but there are currently no safe and effective therapeutic drugs in clinical practice. In recent years, research has found that many alkaloids in traditional Chinese medicine have anti-fibrotic activity, and their mechanisms involved multiple aspects such as cell autophagy, antioxidation, and anti-inflammation. The anti-fibrotic effects and mechanisms of alkaloids from traditional Chinese medicine were reviewed, which could provide reference for the application of alkaloids in the prevention and treatment of hepatic fibrosis.

Fungal infections have emerged as a critical public health issue endangering human health. However, the existing arsenal of antifungal agents is limited in diversity and is commonly plagued by drawbacks including narrow antimicrobial spectrums and the frequent emergence of drug resistance, which severely compromises the efficacy of clinical treatments. Pathogenic fungi can develop extensive adaptability to currently available drugs through multiple mechanisms, which are mainly manifested in three aspects: drug resistance, tolerance and persistence. The molecular mechanisms and regulatory pathways underlying drug resistance, tolerance and persistence in pathogenic fungi were systematically summarized in this review, and the counteractive strategies such as combination therapy and the development of novel antifungal agents were further discussed, which aimed to provide theoretical basis and practical reference for the precision treatment of fungal infections.

Functional constipation (FC) is a clinically common functional bowel disorder characterized by a protracted course and associations with various chronic disorders and psychological abnormalities. Although not life-threatening, FC significantly impairs patients' quality of life. FC subtypes include slow-transit constipation (STC), defecatory disorder (DD), and normal-transit constipation (NTC). The pathological mechanisms underlying FC have not been fully elucidated, and overall clinical efficacy remains unsatisfactory. Animal models of FC serve as essential tools for the study of disease mechanisms and the development of novel therapeutics. This article systematically reviews the current state of research on the animal models of FC and identifies that rodents, particularly rats and mice, are the most commonly used species. Dogs and pigs are also employed in complex intervention studies due to their physiological similarities to humans, though their use is limited by housing challenges and ethical considerations. Induction methods vary across different FC subtypes. STC models are primarily established with chemical agents such as loperamide or compound diphenoxylate. DD modeling often involves low-fiber diets combined with methylene blue injection or rectal narrowing. NTC modeling mainly relies on low-fiber dietary interventions. In addition, disease-syndrome combination models based on traditional Chinese medicine (TCM) theory have been developed, encompassing excess patterns such as heat accumulation, cold accumulation, and Qi stagnation, as well as deficiency patterns including Qi deficiency, blood deficiency, Yin deficiency, and Yang deficiency. These are achieved through an approach of disease model + syndrome induction, enabling the integration of mechanisms from both Western and TCM perspectives. Models are evaluated from two aspects: disease and syndrome manifestations (e.g., colonic transit, secretory function, and TCM syndrome indicators such as mental state and body weight) and disease mechanisms (e.g., enteric nervous system, interstitial cells of Cajal, smooth muscle cells, gut microbiota, and metabolites). However, current research still faces challenges such as poor consistency in some models, non-specific interference in mechanism interpretation, insufficient studies on NTC, and lack of TCM tongue and pulse diagnosis in evaluation. Future efforts should focus on optimizing model stability and specificity to provide a more reliable experimental basis for investigating the pathological mechanisms of FC and developing therapeutic agents.

Malignant tumors remain one of the most critical global public threats to human health. The early diagnosis and precise therapeutic interventions are pivotal for improving patient survival rates and prognosis. Gold nanoclusters (Au NCs), distinguished by their ultra-small size (<3 nm), tunable optical properties, and exceptional biocompatibility, have emerged as transformative agents in precision oncology. This comprehensive review systematically summarizes the multifaceted applications of Au NCs in malignant tumor treatment. We discuss their roles as follows. (1) Intelligent delivery vehicles for targeted chemotherapy and controlled release through surface functionalization. (2) Therapeutic agents for chemodynamic therapy (CDT). This capability stems from their intrinsic enzyme-like catalytic activity or potent thioredoxin reductase (TrxR) inhibitory function, which disrupts the intracellular redox homeostasis and effectively activates downstream apoptotic pathways.(3) Direct therapeutic agents are characterized by their energy conversion capabilities: they can either convert absorbed light into heat to directly kill cancer cells, or transfer that photon energy to surrounding oxygen molecules to generate cytotoxic reactive oxygen species (ROS), leading to cell apoptosis or necrosis. (4) Potent radiosensitizers that enhance radiotherapy efficacy by enhancing localized radiation dose and promoting ROS generation. This review systematically summarizes the recent advances in Au NCs as intelligent delivery systems, direct chemotherapeutic agents, phototherapeutic agents, and efficient radiosensitizers in tumor treatment, elucidating how Au NCs overcome traditional therapeutic limitations through synergistic strategy. It establishes a robust theoretical foundation for next-generation nanotheranostic platforms. However, the translation of laboratory findings into functional clinical technologies confronts three significant challenges. First, although researchers can synthesize atomically precise Au NCs, achieving large-scale production of batches with completely consistent structure, size, and surface chemistry remains extremely challenging. To effectively control the final synthetic product, a deep understanding of the characteristics and formation mechanisms of Au NCs is essential. The traditional “trial-and-error” experimental approach faces inherent limitations when dealing with vast combinations of variables, which is time-consuming, labor-intensive, and struggles with systematic exploration and reproducibility. Machine learning has emerged as a powerful tool to bridge fundamental research and clinical application, which can guide experiments in reverse by predicting synthesis success through data mining and multi-variable analysis. In the future, we anticipate to achieve precise prediction and on-demand design of Au NCs’ structure and properties. Secondly, a systematic framework for evaluating the in vivo pharmacokinetics and long-term toxicity of Au NCs is absent. To address this gap, it is crucial to develop advanced imaging methodologies and integrated theranostic platforms. Au NCs, serving as both a therapeutic core and a highly promising photoluminescent material, are key to constructing such platforms through integration with other agents. These multifunctional systems are designed to achieve optimal synergistic therapy by combining multiple treatment modalities. Finally, the investigation of Au NCs is still largely confined to preclinical cellular and animal studies. Progress necessitates comprehensive clinical research to rigorously assess their safety and efficacy across a range of human cancer models, thereby ensuring broad clinical applicability. In summary, Au NCs-based platforms hold immense promise for translation into clinical anticancer therapy.

ObjectiveTo investigate the effect of Tougu Xiaotong capsules (TGXTC) on the regulation of chondrocyte PANoptosis, delay of chondrocyte degeneration, and improvement of the symptoms in knee osteoarthritis (KOA). MethodsIn vivo experiments: 50 male C57BL/6 mice were randomly assigned into five groups (n=10 per group): sham operation group, model group, low-dose TGXTC group (7.2 g·kg-1), high-dose TGXTC group (14.4 g·kg-1), and diclofenac sodium group (0.05 g·kg-1). Except for the sham group, KOA models were established in all other groups using the modified Hulth method. Following successful model induction, the TGXTC groups received daily oral gavage of 7.2 or 14.4 g·kg-1 for 6 weeks, while the diclofenac sodium group received 0.05 g·kg-1 solution daily over the same duration. Model evaluation was performed using Lequesne MG score; micro-computed tomography (micro-CT) was used to scan the knee, hematoxylin-eosin (HE) staining and safranin O-fast green staining were used to observe the morphology of cartilage, transmission electron microscopy (TEM) was used to determine ultrastructural changes of PANoptosis. Multiple immunofluorescence (IF) co-localization assays was performed to detect the co-localization of cleaved Caspase-3, receptor-interacting protein 3 (RlPK3), and the N-terminal domain of gasdermin D (GSDMD-N) in cartilage tissue, while western blot was employed to detect the expression levels of cleaved Caspase-3, RIPK3, and GSDMD-N. In vitro experiments: The knee cartilages of 4-week-old SD rats were isolated, and a chondrocyte in vitro culture system was established through mechanical digestion with 0.2% type Ⅱ collagenase. Second-generation chondrocytes were divided into three groups: the control group, the model group (pretreated with 10 mg·L-1 lipopolysaccharide (LPS) for 24 h followed by treatment with 1 μmol·L-1 nigericin for 4 h), and the TGXTC treatment group (pretreated with 10 mg·L-1 LPS for 24 h, followed by exposure to 1 μmol·L-1 nigericin for 4 h and subsequently treated with 100 mg·L-1 TGXTC for an additional 24 h). The levels of reactive oxygen species (ROS), apoptosis, necroptosis, and pyroptosis of chondrocytes were evaluated via fluorescence microscopy following staining with ROS detection, AO/EB and YO-PRO-1/PI staining kits. Transmission electron microscopy was utilized to investigate the ultrastructural changes associated with PANoptosis in cartilage tissue of KOA mice. Inflammatory cytokine levels (IL-1β and IL-18) were measured using ELISA. Western blot was conducted to assess protein expressions related to PANoptosis, including cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3. ResultsCompared with the sham group, the Lequesne MG scores were significantly up-regulated(P<0.01) in the model group, and the pathological changes of cartilage were significantly, with joint spaces narrower, osteophyte formation increased, secere abrasion of cartilage surface. Ultrastructural analysis revealed pronounced chondrocyte apoptosis, necroptosis, and pyroptosis, along with markedly elevated expression of cleaved Caspase-3, RlPK3, and GSDMD-N in cartilage tissue (P<0.01). In addition, The mean fluorescence intensities of ROS, orange-red fluorescence in AO/EB staining, green fluorescence and red fluorescence in YO-PRO-1/PI staining were increased of chondrocyte in the model group (P<0.01) . The levels of inflammatory factors IL-1β and IL-18 in the supernatant were increased (P<0.01). The expression of PANoptosis related proteins (cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3) were also significantly upregulated(P<0.05). Compared to the model group, the TGXTC group demonstrated a significant improvement in various parameters of mice. These included a reduction in the Lequesne MG score, an increase in joint space, a decrease in osteophyte formation, diminished cartilage damage, reduced release of ROS, and alleviation of apoptotic, necroptotic, and pyroptotic processes in chondrocytes. Additionally, mitochondrial swelling and endoplasmic reticulum dilation were also mitigated. The levels of ROS as well as IL-1β and IL-18 were significantly decreased (P<0.05). Furthermore, the expression levels of proteins associated with PANoptosis in cartilage tissue showed marked reductions (P<0.05). Similar results were observed in chondrocytes: cleaved Caspase-3, cleaved Caspase-8, RIPK3, ZBP1, GSDMD-N, and NLRP3 exhibited significant decreases as well (P<0.05). ConclusionTGXTC may mitigate chondrocytes degeneration and alleviate KOA symptoms by reducing oxidative stress and suppressing the activation of PANoptosis pathways.
