ObjectiveTo identify potential influencing factors of urate crystal deposition at ankle/foot in patients with hyperuricemia (HUA), and to analyze the predictive value of inflammatory indicators for urate crystal deposition in patients with different traditional Chinese medicine (TCM) syndromes, so as to provide potential reference for clinical risk assessment and individualized TCM intervention. MethodsA retrospective study was carried out with the enrollment of 231 HUA patients from The Third Affiliated People's Hospital of Fujian University of Traditional Chinese Medicine between January 2021 and December 2024. The enrolled patients were further divided into a crystal deposition-positive group (143 cases) and a crystal deposition-negative group (88 cases) according to the results of dual-energy computed tomography (CT). Sociodemographic data, living habits, serum uric acid levels, and inflammatory indicators of the enrolled patients were collcted, and TCM syndrome differentiation was performed. Furthermore, univariate analysis was used to compare inter-group differences in clinical characteristics. MMultivariate Logistic regression was applied to identify the influencing factors of urate crystal deposition. In addition, the receiver operating characteristic (ROC) curves were plotted to evaluate the predictive efficacy of inflammatory indicators for crystal deposition across different TCM syndromes. ResultsThere were statistically significant inter-group differences in the proportion of males, age, body mass index, proportion of mental labor, rate of low water intake, and rate of high-sugar beverage consumption (P<0.05),whereas no significant difference in low exercise intensity was found between the two groups. Furthermore, compared with the negative group, the positive group had higher serum uric acid level, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), but lower systemic immune-inflammation index (SIRI) (P<0.05). Regarding the distribution of TCM syndromes, the positive group was dominated by the dampness-heat accumulation syndrome (55/143,38.46%), while the negative group was mainly characterized by the phlegm-turbidity obstruction syndrome (44/88,50.00%). Multivariate Logistic regression analysis revealed that high-sugar beverage consumption, elevated NLR, and elevated PLR were risk factors for urate crystal deposition [odd ratio (OR) = 8.002, 5.377, 1.034, respectively; 95% CI 1.572-40.732, 2.179-13.270, 1.013-1.054,all P<0.05], while SIRI was a protective factor (OR = 0.869, 95% CI 0.778-0.971, P<0.05). In the positive group, patients with the dampness-heat accumulation syndrome exhibited the highest NLR, while the lowest PLR and SIRI, showing statistically significant differences with those of other syndromes (all P<0.05). In addition, ROC curve analysis indicated that for the dampness-heat accumulation syndrome, the combined "NLR + PLR" model had an area under the curve (AUC) of 0.901 (95% CI 0.850-0.951, P<0.01), with a sensitivity of 89.1% and a specificity of 79.5%; for the blood stasis-heat obstruction syndrome, the combined "NLR + PLR" model had an AUC of 0.880 (95% CI 0.825-0.934, P<0.01), with a sensitivity of 100.0% and a specificity of 67.3%; for the liver-kidney Yin-deficiency syndrome, the single PLR model had an AUC of 0.842 (95% CI 0.731-0.952, P<0.01), with a sensitivity of 83.3% and a specificity of 84.0%. ConclusionUrate crystal deposition in HUA patients exhibits intimate associations with high-sugar beverage consumption as well as elevated NLR and PLR levels. Meanwhile, TCM syndrome differentiation has potential correlation with inflammatory characteristics. The inflammatory indicator-based prediction model constructed based on TCM syndromes exhibits good predictive value.

ObjectiveBased on the clinical characteristics of chronic gouty arthritis (CGA) in both traditional Chinese and western medicine, this study aims to systematically evaluate the clinical concordance of existing CGA animal models, providing recommendations for establishing animal models that align with the pathological characteristics of CGA and the manifestations of traditional Chinese medicine syndromes. MethodsBy comprehensively retrieving Chinese and international databases such as China National Knowledge Infrastructure, Wanfang, VIP Chinese Science and Technology Periodical Database (VIP), and PubMed, all relevant literature on CGA animal models was collected. Based on the guidelines, the diagnostic criteria of both traditional Chinese and western medicine were summarized and organized. The evaluation indicators for the CGA model were constructed with reference to existing evaluation modes, and the CGA animal models were analyzed to systematically evaluate the clinical concordance of existing models. ResultsThe current methods used to construct CGA animal models mainly include monosodium urate crystal induction, high-protein diet induction (poultry lack urate oxidase), and high-fat diet combined with urate oxidase inhibitors and joint injection. Based on 11 pieces of included literature, the traditional Chinese and western medicine scoring data of each model were extracted, and the average scoring values of all models were ultimately calculated. The results show that the average clinical concordances of existing CGA animal models in both traditional Chinese and western medicine are 43.33% and 64.44%, respectively. Among them, the model with the highest clinical concordance rate is the one with a high-fat diet combined with potassium oxonate to induce hyperuricemia plus joint injection, achieving 83.33% clinical concordance in western medicine and 60% in traditional Chinese medicine. This model aligns well with the pathogenic characteristics and pathological changes of clinical CGA. ConclusionAlthough current CGA animal models can simulate some pathological characteristics of CGA, they struggle to comprehensively reflect the complex pathological processes of CGA and the characteristics of traditional Chinese medicine syndromes. Therefore, in the future, it is necessary to establish the CGA animal models that incorporate the clinical disease and syndrome characteristics of traditional Chinese and western medicine and formulate the uniform model evaluation criteria, providing more precise tools for CGA mechanism research and the development of traditional Chinese medicine.

ObjectiveTo evaluate the therapeutic effect of Huazhuo SanJie Chubi presciption (HSCD) on chronic gouty arthritis (CGA) rats with low-grade inflammation and to explore the underlying mechanism with a focus on macrophage polarization. MethodsThe 41 male 6-week-old SD rats were randomly allocated, using the random number table, to a normal group (n=8) and a model group (n =33). CGA with low-grade inflammation was induced in the model group by daily gavage of potassium oxonate (250 mg·kg-1·d-1) and hypoxanthine (300 mg·kg-1·d-1), combined with intra-articular injection of a monosodium urate (MSU) crystal suspension (50 μL, 25 g·L-¹) into the left ankle twice weekly. After 4 weeks of modeling, 3 rats were randomly selected from each group for model validation. The remaining successfully modeled rats were randomly divided into a model group, an HSCD group (10.35 g·kg-1·d-1, gavage once daily), an M1 polarization agonist group (L-methionine sulfoximine, 300 mg·kg-1, subcutaneous injection every other day), an M1 polarization agonist + HSCD group, an M2 polarization inhibitor group (PD0325901, 10 mg·kg-1·d-1, gavage once daily), and M2 polarization inhibitor + HSCD group. The corresponding drug or drug combination was administered according to group assignment, whereas rats in the normal and model groups received 0.5% carboxymethyl cellulose sodium (CMC-Na) vehicle (10.35 g·kg-1·d-1, gavage once daily). All interventions were continued for four weeks. During the intervention period, except for the normal group, potassium oxonate (250 mg·kg⁻¹) and hypoxanthine (300 mg·kg-1) were co-administered by gavage every other day to maintain the model. At the end of treatment, serum uric acid (SUA), ankle joint diameter and joint swelling index were measured. The levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), chemokine C-C motif ligand 2 (CCL2), S100 calcium-binding protein A8/A9 (S100A8/A9), interleukin-10 (IL-10) and arginase-1 (Arg-1) in serum and joint fluid were determined by enzyme-linked immunosorbent assay (ELISA). High-frequency ultrasound was used to assess MSU deposition in the ankle joint. Hematoxylin-eosin (HE) staining was performed to evaluate synovial histopathological changes. Quantitative Real-time PCR and immunofluorescence were used to detect the mRNA and protein expression of the M1 macrophage polarization markers inducible nitric oxide synthase (iNOS) and the M2 macrophage polarization marker scavenger receptor cysteine-rich type 1 protein M130 (CD163) in synovial tissue. ResultsCompared with the normal group, the model group showed significantly elevated SUA level and joint swelling index, and increased levels of pro-inflammatory cytokines, CCL2, and S100A8/A9 in both serum and joint fluid (P<0.05), accompanied by MSU deposition and synovial inflammation in the ankle joint. The mRNA and protein expression levels of macrophage polarization M1/M2 markers iNOS and CD163 in synovial tissues were also significantly up-regulated (P<0.05). Compared with model group, rats in HSCD group had significantly lower SUA levels, attenuated joint swelling, reduced serum levels of pro-inflammatory cytokines, and decreased levels of CCL2 and S100A8/A9 in both serum and joint fluid, accompanied with alleviated MSU deposition and synovial inflammation (P<0.05). HSCD markedly downregulated the mRNA and protein expression of M1 marker iNOS (P<0.05), whereas it had no significant effect on the expression of M2 marker CD163. Compared with the M1 polarization agonist group, the M1 polarization agonist + HSCD group showed significantly reduced joint swelling, lower serum levels of pro-inflammatory cytokines, and decreased levels of CCL2 and S100A8/A9 in joint fluid (P<0.05). In addition, synovial inflammatory cell infiltration and angiogenesis were attenuated, and iNOS mRNA and protein expression levels were significantly reduced (P<0.05). Compared with the M2 polarization inhibitor group, the M2 polarization inhibitor + HSCD group exhibited reduced joint swelling, decreased levels of CCL2 and S100A8/A9 in joint fluid and ameliorated synovial inflammation (P<0.05), whereas the levels of anti-inflammatory mediators (IL-10, Arg-1) and CD163 mRNA and protein expression were not significantly increased. ConclusionHSCD alleviates low-grade inflammation in CGA rats, at least in part, by inhibiting macrophage polarization toward the M1 phenotype.

Ulcerative colitis (UC), a chronic relapsing inflammatory bowel disease, involves multifaceted pathological mechanisms such as intestinal barrier dysfunction, immune dysregulation, and oxidative stress. Current therapeutic strategies remain limited in efficacy and safety. In recent years, the adenosine monophosphate-activated protein kinase (AMPK) signaling pathway has emerged as a pivotal therapeutic target for UC due to its central role in energy metabolism, inflammatory regulation, and intestinal homeostasis. This article systematically reviewed the mechanisms by which traditional Chinese medicine (TCM) prevented and treated UC through the regulation of the AMPK signaling pathway, with a focus on elucidating AMPK's multidimensional regulatory network in inflammatory signaling crosstalk, alleviating oxidative stress, restoring intestinal immune balance, repairing the intestinal barrier, and modulating gut microbiota. Leveraging its unique advantages of multi-target engagement and low toxicity, TCM demonstrates promising potential in UC treatment and has become a focal area of research. By systematically summarizing and synthesizing the existing literature on TCM-mediated AMPK pathway modulation in UC, this review aims to provide a theoretical foundation for advancing mechanistic research and clinical interventions in UC.

ObjectiveTo investigate whether visceral fat area (VFA) is an independent risk factor for significant liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) based on clinical data, and to establish an effective diagnostic model. MethodsA total of 222 NAFLD patients who attended Department of Hepatology, Guangdong Provincial Hospital of Traditional Chinese Medicine, from January 2021 to April 2025 were enrolled, and according to liver stiffness measurement (≥8 kPa or not), they were divided into significant fibrosis group and non-significant fibrosis group. Propensity score matching (PSM) was performed at a ratio of 1∶1 to balance the baseline data between the two groups. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between groups. A Spearman correlation analysis was used to determine the correlation of VFA and other indicators with significant liver fibrosis; univariate and multivariate logistic regression analyses were used to identify whether VFA was an independent risk factor for significant liver fibrosis in NAFLD patients, and the receiver operating characteristic (ROC) curve was plotted to assess the predictive performance of related indicators. ResultsA total of 45 patients with significant liver fibrosis and 177 patients without significant liver fibrosis were enrolled, and after PSM, 90 patients (45 pairs) were finally included in analysis. Compared with the non-significant fibrosis group, the significant fibrosis group had significantly higher levels of body mass index (BMI), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), controlled attenuation parameter (CAP), and VFA, as well as a significantly higher proportion of patients with visceral fat obesity or three or more metabolic risk factors (all P<0.05). VFA, BMI, AST, and HbA1c were strongly correlated with significant liver fibrosis (all r>0.5, all P <0.05), and ALT, GGT, UA, FBG, and CAP were significantly positively correlated with significant liver fibrosis (r=0.3 — 0.5, all P<0.05). VFA (odds ratio [OR]=1.040, 95% confidence interval [CI]: 1.018 — 1.062, P<0.05), FBG (OR=2.372, 95%CI: 1.199 — 4.691, P<0.05), and AST (OR=1.032, 95%CI: 1.003 — 1.058, P<0.05) were independent risk factors for significant liver fibrosis in NAFLD patients. The new diagnostic model based on VFA, FBG, and AST (with an area under the ROC curve [AUC] of 0.907) had a significantly better performance than aspartate aminotransferase-to-platelet ratio index (AUC=0.834), fibrosis-4 (AUC=0.660), triglyceride-glucose index (AUC=0.656), and NAFLD fibrosis score (AUC=0.768) in predicting significant liver fibrosis in NAFLD patients (all P<0.05). ConclusionVFA is an independent risk factor for significant liver fibrosis in NAFLD patients, and the noninvasive diagnostic model based on VFA, FBG, and AST can effectively predict the onset of significant liver fibrosis in NAFLD patients.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors (DTIs) in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital (the Affiliated Hospital of UESTC), a multidisciplinary working group was established. Through literature review and the Delphi method, clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework; systematic searches were conducted in CNKI, Medline, Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment,Development and Evaluation (GRADE) approach, and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations (each with an expert consensus rate exceeding 90%) on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection, dosing ranges, key monitoring points, and safety management strategies for parenteral DTIs in various scenarios, including the perioperative period of ventricular assist device implantation, the perioperative period of cardiac surgery, perioperative patients with lower-extremity atherosclerotic disease, the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome, the perioperative period of carotid artery stenting in patients with carotid stenosis, the perioperative period of patients with right heart thrombosis, and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition, warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus, which is formulated based on the best available evidence, provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

To investigate the clinical efficacy of neoadjuvant imatinib in the treatment of rectal gastrointestinal stromal tumor (GIST). Patients with rectal GIST who underwent surgery at Peking Union Medical College Hospital from January 2015 to January 2025 were included. Clinical data were retrospectively analyzed. Patients were divided into the neoadjuvant therapy group (received preoperative imatinib) and the control group (underwent direct surgery without preoperative imatinib). Clinical outcomes and recurrence rates were compared between the two groups. A total of 74 patients meeting the inclusion criteria were included, with 43 included in the neoadjuvant therapy group and 31 included in the control group. Baseline evaluation showed that the median tumor diameter was significantly larger in the neoadjuvant therapy group than that in the control group [5.0(2.9, 7.1)cm Neoadjuvant therapy with imatinib can effectively reduce tumor volume in patients with rectal GIST. However, its therapeutic benefit still needs to be further validated by prospective, large-sample clinical studies with long-term follow-up.

ObjectiveTo explore the effect and mechanism of Taishan Panshi powder (TSPSP) on inhibiting oxidative stress injury in human chorionic trophoblast cells (HTR-8/SVneo), and to uelucidate the underlying mechanism of TSPSP in the treatment of spontaneous abortion (SA). MethodsGene differential analysis of SA was performed using the Gene Expression Omnibus (GEO) database and correlated with oxidative stress. Network pharmacology was employed to screen the active components of TSPSP, and a "Chinese medicine-component-target-disease" network was constructed to predict the mechanism of action of TSPSP. For in vitro validation experiments, HTR-8/SVneo cells were divided into blank group, model group, TSPSP-containing serum 2.5%, 5%, 10% groups, and nuclear factor E2-related factor 2 (Nrf2) inhibitor group (ML385, 30 μmol·L-1). Except for the blank group, other groups were stimulated with 150 μmol·L-1 H2O2 for 3 h to establish a cell oxidative stress injury model. After successful modeling, the blank group and model group were given 10% blank serum, each TSPSP-containing serum group was treated with the corresponding concentration of drug-containing serum, and the Nrf2 inhibitor group was additionally given 30 μmol·L-1 ML385 on the basis of 10% TSPSP-containing serum. All groups of cells were continuously cultured under the above conditions for 24 h, and then samples were collected for subsequent detection. Cell viability in each group was detected by CCK-8 assay. Cell migration rate was detected by scratch test. The contents of malondialdehyde (MDA), Fe2+, and Glutathione (GSH) were detected by enzyme-linked immunosorbent assay (ELISA). Intracellular reactive oxygen species (ROS) level was detected by a fluorescent probe (DCF-DA). The protein and mRNA expression levels of Kelch-like ECH-associated protein 1 (KEAP1), Nrf2, and forkhead box protein O3 (FoxO3) in cells were detected by immunofluorescence (IF) and real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of KEAP1, Nrf2, FoxO3, Glutathione peroxidase 4 (GPX4), and superoxide dismutase (SOD) in cells were detected by Western blot. ResultsThe GSE76862 and GSE22490 datasets were obtained from the GEO database. Differential gene analyses showed that the KEAP1, Nrf2, and FoxO3 genes were all associated with the disease. After matching with the oxidative stress pathway, nine significantly differential pathways were identified (P<0.05), among which three contained the target genes Nrf2 and FoxO3. A total of 246 active ingredient targets of TSPSP and 2 804 SA-related targets were obtained through network pharmacology, and 154 potential action targets were obtained after taking the intersection. Topological analysis showed that targets such as KEAP1 and Nrf2 exhibited high degree values. GO and KEGG enrichment analyses indicated that the intersection targets were mainly involved in oxidative stress response, FOXO and MAPK signaling pathways, etc. In in vitro experiments, compared with the blank group, the cell viability in the model group was significantly decreased (P<0.01). Compared with the model group, the cell viability in each TSPSP-containing serum group was significantly increased (P<0.01). Compared with the 10% TSPSP-containing serum group, the cell viability in the ML385 group decreased to approximately 70% (P<0.01). Compared with the blank group, the model group showed significantly increased contents of MDA, Fe2+, and ROS, decreased GSH expression (P<0.01), significantly reduced cell migration rate (P<0.01), and increased protein and mRNA expression levels of KEAP1 and FoxO3 (P<0.01), while decreased protein and mRNA expression levels of Nrf2, GPX4, and SOD (P<0.01). Compared with the model group, each TSPSP-containing serum group showed significantly decreased contents of MDA, Fe²⁺, and ROS, increased GSH expression (P<0.01), significantly increased migration rate (P<0.01), significantly decreased protein and mRNA expression levels of KEAP1 and FoxO3 (P<0.05, P<0.01), and significantly increased protein and mRNA expression levels of Nrf2, GPX4, and SOD (P<0.05, P<0.01). Compared with the 10% TSPSP-containing serum group, the ML385 group showed reversed trends in all indicators (P<0.05, P<0.01). ConclusionTSPSP can inhibit H2O2-induced oxidative stress injury of trophoblast cells, and its mechanism of action may be related to the drug activating the KEAP1/Nrf2/FoxO3 signaling pathway.
