In recent years, traditional Chinese medicine (TCM) has achieved significant progress in the treatment of inflammatory bowel disease (IBD). A comprehensive literature search was conducted covering the period from January 1, 2010, to December 30, 2024, across Chinese databases including China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP China Science and Technology Journal Database, and the Chinese Biomedical Literature Service System, as well as international databases such as PubMed, Web of Science, and Embase. The clinical applications and mechanistic studies of TCM in IBD were systematically reviewed. The current status of TCM research on the etiology and pathogenesis of IBD, innovative clinical practices, and multimodal therapeutic approaches, including Chinese herbal formulas, single herbs or active compounds, acupuncture, herbal retention enema, and acupoint application, were summarized, together with their synergistic effects when combined with western medical treatments. The development and application of Chinese patent medicines for IBD are undergoing a profound transition from efficacy validation to mechanistic exploration. Mechanistic studies on the effects of TCM in IBD mainly focus on regulating gut microbiota homeostasis, repairing the intestinal mucosal barrier, and modulating intestinal immune balance. Furthermore, future research directions for TCM-based IBD management are proposed, including the establishment of TCM diagnostic and treatment models, expanding integrated applications of external and internal TCM therapies, innovating personalized treatment strategies, and advancing drug development. These efforts aim to provide insights for the standardized and precision-oriented development of TCM in the diagnosis and treatment of IBD.

As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

ObjectiveTo investigate the efficacy and underlying mechanisms of Gynostemma pentaphyllum alcohol extract in improving glucose and lipid metabolism disorders in db/db mice through transcriptomics and gut microbiota analysis. MethodsEighteen db/db mice were randomly assigned to the model(DM) group, metformin(MET) group, and G. pentaphyllum alcohol extract(GP) group, with six mice in each group, based on stratification of fasting blood glucose and body weight. An additional six db/m mice were selected as the normal control(NC) group. Mice in the NC and DM groups were administered deionized water (10 mL·kg-1) daily. The MET group received metformin (0.195 g·kg-1) by gavage. The GP group was treated with G. pentaphyllum alcohol extract (3.9 g·kg-1) by gavage for six weeks. Fasting blood glucose was measured every two weeks. After six weeks of intervention, serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), and blood urea nitrogen (BUN) were assessed. Enzyme-linked immunosorbent assay (ELISA) was used to measure insulin (FINS), adiponectin (ADP), and tumor necrosis factor-α (TNF-α). Hematoxylin-eosin (HE) staining was used to observe liver histomorphology, periodic acid-Schiff (PAS) staining was employed to assess hepatic glycogen synthesis, and Oil Red O staining was used to detect hepatic lipid deposition. Liver transcriptomic data were used to identify differentially expressed genes in the liver and conduct enrichment analysis. Real-time PCR was employed to verify the expression levels of adiponectin gene (Adipoq), peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor α (PPARα), glucokinase (GCK), forkhead box (Fox)O1, FoxO3, phosphoenolpyruvate carboxykinase (PEPCK), and glucose-6-phosphatase (G6PC). Metagenomic sequencing was conducted to analyze changes in gut microbiota composition. ResultsCompared with the NC group, the DM group exhibited significantly elevated fasting blood glucose (P<0.01), serum AST, ALT, TC, TG, LDL-C, and HDL-C (P<0.01). FINS, homeostatic model assessment for insulin resistance (HOMA-IR), and the inflammatory cytokine TNF-α were significantly increased (P<0.01), while ADP was significantly decreased (P<0.05). Histological analysis confirmed severe hepatic steatosis and excessive lipid accumulation in the DM group, along with markedly reduced glycogen synthesis. Compared with the DM group, the GP group showed significantly decreased fasting blood glucose (P<0.01), reduced serum TC, LDL-C, and HDL-C levels (P<0.05), significantly decreased serum TG and AST levels (P<0.01), significantly reduced FINS, HOMA-IR, and TNF-α levels (P<0.01), and significantly increased ADP (P<0.01). Hepatic steatosis and lipid deposition were significantly alleviated, while glycogen synthesis was markedly enhanced. Transcriptomic differential and enrichment analyses suggested that the mechanisms by which G. pentaphyllum alcohol extract improved hepatic glucose and lipid metabolism in db/db mice may involve regulation of the AMPK and FoxO signaling pathways. Real-time PCR results confirmed that expression of PGC-1α, PEPCK, G6PC, FoxO1, and FoxO3 was significantly downregulated following treatment with G. pentaphyllum alcohol extract (P<0.05, P<0.01), whereas mRNA expression of Adipoq, PPARα, GCK, and AMPK was significantly upregulated (P<0.05, P<0.01). Metagenomic analysis showed that the relative abundance of Lactobacillus, Alistipes, and Akkermansia species was higher in the GP group than in the DM group. ConclusionG. pentaphyllum alcohol extract may improve glucose and lipid metabolism disorders in db/db mice by regulating the hepatic AMPK/PPARα pathway to suppress lipid deposition and alleviate hepatic steatosis, by inhibiting gluconeogenesis through the AMPK/PGC-1α and FoxO pathways to lower fasting blood glucose, and by increasing the abundance of beneficial gut bacteria such as Lactobacillus, Alistipes, and Akkermansia to restore gut microbiota balance.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

In recent years, the reform of the registration, evaluation, and approval system for traditional Chinese medicine(TCM) has been promoted at the national level, with establishment of an evaluation evidence system for TCM registration that combines TCM theory, human use experience, and clinical trials(known as the "three-combined" evaluation evidence system). This system, which aligns with the characteristics of TCM clinical practice and the laws of TCM research and development, recognizes the unique value of human use experience in medicine and returns to the essence of medicine as an applied science, thus receiving widespread recognition from both academia and industry. However, it meanwhile poses new and higher challenges. This article delves into the value and challenges faced by the "three-combined" evaluation evidence system from three perspectives: registration management, medical institutions, and the TCM industry. Furthermore, it discusses how the China Association of Chinese Medicine, leveraging its academic platform advantages and leading roles, has made exploratory and practical efforts to facilitate the research and development of new TCM drugs and the implementation of the "three-combined" evaluation evidence system.

OBJECTIVE:
To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM).
METHODS:
This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis.
RESULTS:
Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings.
CONCLUSIONS
RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Cough variant asthma (CVA) is a chronic respiratory disease with cough as its main symptom. The occurrence of CVA is closely related to non-specific airway inflammation, and its pathogenesis involves environmental, genetic, immune, and other factors. In recent years, the advantages of traditional Chinese medicine (TCM) in the treatment of CVA have attracted the attention of experts and scholars in China and abroad, especially its prominent role in regulating immune balance, relieving cough symptoms in CVA patients, and reducing recurrence. T Helper cells 1 (Th1), T helper cells 2 (Th2), T helper cells 17 (Th17), and regulatory T cells (Treg) are derived from CD4+ T cells. Immune imbalance of Th1/Th2 and Th17/Treg is a new hotspot in the pathogenesis of CVA and a potential key target in the treatment of CVA by TCM. Th cell subsets are in dynamic balance under physiological conditions, maintaining respiratory immune homeostasis in which pro-inflammatory cytokines and anti-inflammatory cytokines are balanced. Immature helper T cells (Th0) can be differentiated into Th1, Th2, Th17, Treg, and other cell subsets due to cytokine types in the microenvironment in the stage of CVA maturation. The proliferation of Th2 cells leads to eosinophilic airway inflammation. Excessive differentiation of Th17 cells induces neutrophil airway inflammation. Th1/Th2 and Th17/Treg cells are mutually restricted in number and function, and the immune imbalance of Th1/Th2 and Th17/Treg is easy to aggravate the generation of inflammatory response. Restoring immune balance is particularly important for the airway anti-inflammatory therapy of CVA. In this paper, the imbalance of Th1/Th2 and Th17/Treg and the pathogenesis of CVA were systematically expounded. Meanwhile, the latest research on the regulation of immune imbalance by TCM compound, single TCM, and its effective ingredients in the treatment of CVA was reviewed. It provides ideas and references for revealing the scientific connotation of TCM regulating immune balance therapy of CVA, as well as the development of clinical treatment and basic research of CVA.

ObjectiveTo investigate the effect of modified Weijingtang on the pyroptosis of RAW264.7 macrophages via the cysteinyl aspartate-specific protease-1 (Caspase-1)/gasdermin D (GSDMD) pathway. MethodLipopolysaccharide (LPS) was used to induce pyroptosis of RAW264.7 cells. The blank group was treated with the blank serum, and the intervention groups were treated with the sera containing different doses of modified Weijingtang. After 24 h, the viability of cells in different groups was examined by the cell counting kit-8 (CCK-8). The pyroptosis and morphology of cells in each group were observed by a scanning electron microscope and a phase-contrast microscope, respectively. The mRNA and protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), Caspase-1, and GSDMD in each group were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. The levels of interleukin (IL)-18 and IL-1β in each group were measured by enzyme-linked immunosorbent assay. ResultUnder the electron microscope, RAW264.7 cells presented the best morphology and structure in the blank group and obvious pyroptosis and leakage of cell contents in the model (LPS) group. Compared with the model group, the intervention groups showed reduced pyroptosis to varying degrees, and the high-dose group had the closest cell morphology and structure to the blank group. Under the optical microscope, RAW264.7 cells were spherical in the blank group and irregular with protrusions in the model group. Compared with the model group, the intervention groups showed improved cell morphology, and the cell morphology in the group with the dose of 20% was the closest to that in the blank group. The mRNA and protein levels of NLRP3, Caspase-1, and GSDMD in the model group were higher than those in the blank group (P<0.05). Compared with the model group, each intervention group showed down-regulated expression of the above indicators (P<0.05). Compared with the blank group, the model group presented elevated levels of IL-18 and IL-1β (P<0.05), which were lowered in the intervention (10%, 20%) groups (P<0.01). ConclusionModified Weijingtang inhibits the pyroptosis of macrophages by down-regulating the Caspase-1/GSDMD pathway and reducing the release of proinflammatory cytokines.
