ObjectiveTo investigate the effect of quercetin on acute gouty arthritis （GA） in rats by inhibiting the reactive oxygen species （ROS）/NOD-like receptor protein 3 （NLRP3）/interleukin-1β （IL-1β） signaling pathway. MethodsSixty SPF-grade male SD rats were randomized into normal， model， colchicine （0.3 mg·kg^-1）， and low-， medium-， and high-dose （25， 50， 100 mg·kg^-1， respectively） quercetin groups （n=10）. The rats in the dosing groups were administrated with the corresponding drugs （10 mL·kg^-1） by gavage once a day for one week. An equal volume of normal saline was given by gavage to rats in normal and model groups. One hour after drug administration on day 5， an acute GA model was established in other groups except the control group via intra-articular injection of monosodium urate （MSU） suspension into the right posterior ankle joint cavity. The joint swelling and gait were scored at the time points of 6， 12， 24， 48 h after modeling. Histopathological alterations in the ankle joint tissue from each group were assessed by hematoxylin-eosin （HE） staining. Malondialdehyde （MDA）， xanthine oxidase （XOD）， and total superoxide dismutase （T-SOD） assay kits were used to assess the levels of MDA， XOD， and T-SOD in the serum. The levels of tumor interleukin-6 （IL-6）， necrosis factor-α （TNF-α）， and IL-1β in the rat serum， as well as ROS in the ankle joint tissue， were measured by enzyme-linked immunosorbent assay （ELISA）. Western blot was performed to determine the protein levels of NLRP3， thioredoxin-interacting protein （TXNIP）， apoptosis-associated speck-like protein containing a CARD domain （ASC）， precursor cysteinyl aspartate-specific proteinase-1 （pro-Caspase-1）， cleaved Caspase-1 （Caspase-1 p20）， and IL-1β in the ankle joint tissue. Real-time PCR was employed to assess the mRNA levels of TXNIP， NLRP3， ASC， IL-1β， and TNF-α in the ankle joint tissue. ResultsCompared with the normal group， the model group exhibited decreased spontaneous activity， mental fatigue， increased ankle joint swelling and gait scores （P<0.01）， aggravated synovial tissue edema and inflammatory cell infiltration （P<0.01）， elevated levels of XOD， MDA， TNF-α， IL-1β， and IL-6 in the serum and ROS in the joint tissue （P<0.01）， a declined level of T-SOD （P<0.01）， up-regulated protein levels of NLRP3， TXNIP， ASC， pro-Caspase-1， Caspase-1 p20， and IL-1β in the ankle joint tissue （P<0.01）， and up-regulated mRNA levels of NLRP3， TXNIP， ASC， IL-1β， and TNF-α in the ankle joint tissue （P<0.01）. Compared with the model group， the medium- and high-dose quercetin groups showed improved general conditions， decreased gait scores （P<0.05， P<0.01）， reduced joint swelling （P<0.01）， alleviated synovial tissue edema and inflammatory cell infiltration （P<0.05， P<0.01）， lowered levels of XOD， MDA， TNF-α， IL-1β， and IL-6 in the serum and ROS in the joint tissue （P<0.01）， increased levels of T-SOD （P<0.01）， down-regulated protein levels of TXNIP， NLRP3， ASC， pro-Caspase-1， Caspase-1 p20， and IL-1β in the ankle joint tissue （P<0.05， P<0.01）， and down-regulated mRNA levels of TXNIP， NLRP3， ASC， IL-1β， and TNF-α in the ankle joint tissue （P<0.01）. Low-dose quercetin also ameliorated some of the above parameters （P<0.05， P<0.01）. ConclusionQuercetin exerts anti-GA effects by blocking the ROS/NLRP3/IL-1β signaling pathway， downregulating NLRP3 inflammasome activation， and inhibiting the production of pro-inflammatory cytokines including TNF-α， IL-1β， and IL-6.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.

ObjectiveTo investigate the chemosensitization effect of gallic acid （GA） combined with sorafenib （Sora） on hepatocellular carcinoma HepG2 cells and related mechanisms. MethodsHepG2 cells were randomly divided into control group， GA group， Sora group， and GA+Sora group. CCK8 assay was used to measure cell viability； CompuSyn software was used to analyze combination index （CI）； colony formation assay was used to evaluate the colony formation ability of cells； flow cytometry was used to measure cell apoptosis； wound healing assay and Transwell chamber assay were used to observe the migration and invasion abilities of cells； Western Blot was used to measure the expression matrix metalloproteinase 2 （MMP-2）， matrix metalloproteinase 9 （MMP-9）， and apoptosis-related proteins. HepG2 cells were subcutaneously inoculated into the lower right back of mice， and 6 days later， the mice were divided into control group， GA group， Sora group， and GA+Sora group. Tumor size and body weight were measured once a week， and drug intervention was performed for 21 days. Then the nude mice were sacrificed， and tumor weight was measured. A one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsThe mean IC₅₀ values of GA and Sora for the treatment of HepG2 cells for 48 hours were 123.47±5.16 μmol/L and 9.87±0.98 μmol/L， respectively， and when Sora was combined with 70 μmol/L GA （IC₃₀）， IC₅₀ decreased to 2.06±0.35 μmol/L； the CI value was<1 for Sora at different concentrations combined with 70 μmol/L GA. The number of cell colonies was 234.0±20.4， 147.0±12.1， 129.3±13.3， and 73.0±7.6， respectively， in the four groups， and the GA+Sora group had a significantly lower number of cell colonies than the control group， the GA group， and the Sora group （all P<0.05）. After 48 hours of treatment， the cell apoptosis rate was 1.98%±0.29%， 15.17%± 1.56%， 18.65%±1.48%， and 34.60%±5.36%， respectively， in the four groups， and the GA+Sora group had a significantly higher cell apoptosis rate than the control group， the GA group， and the Sora group （all P<0.05）. After 24 hours of treatment， the cell migration rate was 55.59%±5.08%， 29.34%±4.36%， 21.80%±5.16%， and 6.47%±2.75%， respectively， in the four groups， and the GA+Sora group had a significantly lower cell migration rate than the control group， the GA group， and the Sora group （all P<0.05）. After 48 hours of treatment， the number of transmembrane cells was 223.7±13.0， 168.3±10.9， 155.3±29.1， and 62.7±19.7， respectively， in the four groups， and the GA+Sora group had a significantly lower number of transmembrane cells than the control group， the GA group， and the Sora group （all P<0.05）. Compared with the control group， the GA group， the Sora group， and the GA+Sora group had significant reductions in the protein expression levels of MMP-2， MMP-9， and Bcl-2 （all P<0.05） and significant increases in the protein expression levels of Bax and cleaved caspase-3 （all P<0.05）. Compared with the control group， the GA， Sora， and GA+Sora groups had significant reductions in tumor volume and weight （all P<0.05）， and compared with the Sora group， the GA+Sora group had significant reductions in tumor volume and weight in nude mice （both P<0.05）. ConclusionGA can increase the sensitivity of HepG2 cells to Sora chemotherapy， possibly by promoting cell apoptosis and inhibiting cell migration and invasion after combination with Sora.

ObjectiveTo divide the muscle into different subzones according to different density ranges using the stratified analysis on the basis of myosteatosis， and to investigate the effect of muscle density changes on complications （Clavien-Dindo grade ≥Ⅲ） after orthotopic liver transplantation （OLT）. MethodsA retrospective analysis was performed for the medical records of 145 patients who underwent OLT in The First Hospital of Jilin University from May 2013 to September 2020， and with the plain CT scan images of the largest level of lumbar 3 vertebrae of each patient as the original data， Neusoft Fatanalysis software was used to measure related muscle parameters. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test or Fisher test was for comparison of categorical data between two groups. RIAS software was used to extract clinical features and perform analysis and modeling， and three machine learning models of logistic regression （LR）， support vector machine （SVM）， and random forest （RFC） were constructed. The receiver operating characteristic （ROC） curve， the calibration curve， and the decision curve were plotted for each model to calculate the area under the ROC curve （AUC）， sensitivity， specificity， precision， F1 score， and accuracy. ResultsThe three machine learning models of LR-C， SVM-C， and RFC-C were established based on the 7 clinical features before muscle stratification analysis， among which the RFC-C model had an AUC of 0.803， a sensitivity of 0.588， and a specificity of 0.778 in the test set. Among the models of LR-CS， SVM-CS， and RFC-CS established based on the 16 clinical features after muscle stratification analysis， the LR-CS and SVM-CS models had an AUC of 0.852 in the test set， with a sensitivity of 0.765 and 0.706， respectively， and a specificity of 0.889 and 0.926， respectively. Comparison of the AUC， sensitivity， specificity， precision， F1 score， and accuracy of each model in the test set before and after muscle stratification analysis showed that there were improvements in the parameters of the predictive model after muscle stratification analysis. Comparison of the decision curves and calibration curves of each predictive model showed that the LR-CS and SVM-CS models had good efficacy in predicting postoperative complications （Clavien-Dindo grade≥Ⅲ） in OLT patients. ConclusionOn the basis of myosteatosis， the division of the muscle into different subzones according to different densities using the stratified analysis has a certain value in predicting postoperative complications in patients with OLT.

Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

Idiopathic epiretinal membrane(IERM)is an age-related retinal disease of the macula. In early stages, symptoms of IERM are usually characterized by visual impairment. As the disease progresses, it can lead to metamorphopsia and lower visual acuity in severe cases, the pathogenesis of IERM remains a mystery. Researchers have found that posterior vitreous detachment(PVD), anomalous PVD, activation of the renin-angiotensin system(RAS), and glial to mesenchymal transition(GMT)of Müller cells play important roles in the pathogenesis of IERM. In pathological research of IERM, astrocytes, microglia, Müller cells, hyalocytes, fibroblasts, myofibroblasts, and retinal pigment epithelium(RPE)cells were found to be the major cellular components of IERM, and the extracellular matrix of IERM was mainly composed of extracellular collagen fibers. In this article, we summarize the mechanisms of IERM formation in the light of some of the recent advances in research on the pathogeny, cells, cytokines, and extracellular matrix of IERM, in order to provide directions for its prevention and treatment.
