OBJECTIVE To explore the ameliorative effect and potential mechanism of vitexin on inflammation in ulcerative colitis （UC） mice. METHODS The UC mice model was established by continuous administration of 3% dextran sulfate sodium solution for 5 days. Mice with successful modeling were randomly divided into UC group， vitexin low- and high-dose groups （vitexin-L and vitexin-H groups， 40， 80 mg/kg）， mesalazine group （400 mg/kg）， and vitexin-H+recombinant Jagged canonical Notch ligand 1 （rJagged-1） group （vitexin-H+rJagged-1 group， 80 mg/kg vitexin+1 mg/kg rJagged-1）， with 12 mice in each group. Another 12 normal mice were used as the control （CK） group. Mice in each group were administered the corresponding drugs or the corresponding drugs and normal saline by gavage and intraperitoneal injection once daily for 7 consecutive days. General conditions were observed during the experiment. At 24 h after the last administration， the disease activity index （DAI） score was evaluated. Colonic histopathological morphology was observed and scored. Macrophage polarization levels in the spleen and colon tissues were measured. The protein expressions of interleukin-6 （IL-6）， IL-10， tumor necrosis factor-α （TNF-α）， transforming growth factor-β 1 （TGF-β 1 ）， Jagged-1， Notch1 and Notch intracellular domain （NICD） in colonic tissues were determined. RESULTS Compared with the UC group， the symptoms （reduced food and water intake， dull fur， etc.） and pathological changes （epithelial cell shedding， inflammatory cell infiltration， etc.） were significantly improved in the vitexin-L， vitexin-H and mesalazine groups. DAI scores， colonic histopathological scores， M1 macrophage contents in spleen tissue， M1/M2 macrophage ratios， M1 macrophage proportions in colon tissue， and protein expressions of IL-6， TNF-α， Jagged-1， Notch1 and NICD in colon tissue were significantly decreased （ P ＜0.05）. Meanwhile， the M2 macrophage contents in spleen tissue， M2 macrophage proportions in colon tissue， and protein expressions of IL-10 and TGF-β 1 in colon tissue were significantly increased （ P ＜0.05）. Moreover， the improvement effects in the vitexin-H and mesalazine groups were significantly superior to those in the vitexin-L group （ P ＜0.05）. Compared with the vitexin-H group， the above symptoms and pathological changes were aggravated， and all quantitative indicators were significantly reversed in the vitexin-H+rJagged-1 group （ P ＜0.05）. CONCLUSIONS Vitexin can ameliorate the inflammation of UC mice， which is associated with its inhibition of the Jagged-1/Notch1 pathway and regulation of macrophage polarization （inhibition of M1-type polarization and promotion of M2-type polarization）.

The occurrence of diabetes mellitus （DM） is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver，fat，skeletal muscle，islets， and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response，improving insulin resistance，and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing，heat-clearing， and detoxicating medicinal，which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore，by summarizing the mechanisms between macrophage activation，polarization， and insulin resistance in various tissues，this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio，providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

Background Accurate T-staging is critical for esophageal cancer therapy,but CT-based assessment has significant limitations.Large vision models(LVMs)hold promise,yet their zero-shot clinical diagnostic capability without fine-tuning remains unvalidated.Methods A retrospective analysis was conducted on the chest CT images from 98 esophageal cancer patients and 50 normal controls.Using radiologist-consensus as the gold standard,the zero-shot T-staging performance of 3 LVMs(GPT-5,Gemini,and MedGemma)was evaluated with prompts of varying complexity.Results GPT-5 exhibited the highest accuracy and stability.Significant biases were observed among models:Gemini tended to over-stage,while MedGemma showed a tendency to under-stage.All models faced challenges in identifying early-stage tumors,but structured prompts improved diagnostic performance for mid-to-late stage lesions.Conclusion LVMs have potential for zero-shot T-staging,but their performance highly depends on model choice and prompt design.The generic model GPT-5 show superior zero-shot generalization.However,current model performance is not yet clinically viable,especially for early diagnosis.Future work should focus on fine-tuning with high-quality clinical data and developing standardized prompt frameworks.

Objective To investigate the effect of miR-2110 on the biological behaviors,such as cell proliferation,apoptosis,and metastasis,of lung adenocarcinoma(LUAD)cells by means of cell and animal experiments.Methods Bioinformatics websites,including ENCORI,TargetScan,miRTarBase,and Tarbase,were used to analyze the changes in the expression of miR-2110 in LUAD samples and to predict miR-2110 target.LUAD tissue samples and cells were collected and the changes in the expression of miR-2110 were verified through PCR technology.CCK-8 assay,clonogenic assay,Transwell assay,and flow cytometry were conducted to analyze alterations in the functions of LUAD cells.In addition,10 BALB/c female nude mice aged 6 to 8 weeks were randomly divided into 2 groups,and the effect of miR-2110 on LUAD was investigated by in vivo experiments.Results miR-2110 was significantly decreased in LUAD tissues and cells compared with the normal lung tissues.miR-2110 overexpression inhibited the proliferation and metastasis of LUAD cells and promoted the apoptosis of tumor cells(P＜0.05).Bioinformatics prediction and dual luciferase reporter gene assay results confirmed that miR-2110 could target and bind to CDT1.In addition,overexpression of CDT1 gene reversed the proliferation,metastasis,and apoptosis of miR-2110 compared with the miR-2110 overexpression group(P＜0.05).Nude mice in vivo experiments showed that miR-2110 overexpression significantly decreased the expression of Ki67,a tumor proliferation index,and vimentin and MMP9,two metastasis indices,compared with the control group.Conclusion miR-2110 can inhibit proliferation and metastasis of LUAD by targeting CDT1,providing a new rationale for the treatment of LUAD.

The theory of "linkage between spleen and small intestine" has been put forward by doctors as early as the Ming dynasty. In traditional Chinese medicine， the spleen and small intestine cooperate and work together physiologically， and they are also closely related and interact with each other pathologically. The spleen governs transportation and transformation， which involves the function of the small intestine in transforming water and grain. The small intestine， governing the receiving and transformation of substances， depends on the normal transportation of the spleen. At the same time， it provides guarantee for the spleen to transform Qi and generate blood as well as ascend lucidity and descend turbidity. The dysfunction of spleen in transportation is closely related to the dysfunction of small intestine. The stability of intestinal microecology necessitates the normal functioning of the spleen. When the original balance of intestinal flora is disturbed， the spleen functioning will be affected. This study explored the pathogenesis and treatment of diabetes based on the physiological functions of the spleen and small intestine and the Western medicine targets of "nutrients-intestinal flora". According to modern medicine， nutrients are essential to maintain the normal physiological activities of the human body. Proper intake of nutrients can affect the absorption and metabolism of the human body for nutrients by regulating the composition and function of intestinal flora， so as to prevent the occurrence of diabetes. The imbalance of intestinal flora which harbors rich microorganisms may lead to the disturbance of energy metabolism and the dysfunction of the immune system， eventually leading to diabetes. As a metabolic disease， diabetes is closely related to the imbalance of intestinal flora and nutrient intake. Based on the theory of "linkage between spleen and small intestine"， this paper discusses the relationship between spleen and small intestine. Furthermore， this paper discusses the correlation between "spleen-small intestine" and "nutrients-intestinal flora" by reviewing the latest progress in modern medicine and clinical research， aiming to provide a theoretical basis and new ideas for the clinical prevention and treatment of type 2 diabetes mellitus.

Objective This study aims to investigate the therapeutic effect and mechanism of Naoxinqing on non-alcohol fatty liver disease (NAFLD) induced by a high-fat diet through network pharmacology,molecular docking and in vitro and in vivo experiments. Methods ApoE-/-mice were given a high-fat diet for 12 weeks to establish the NAFLD model,followed by a 12-week Naoxinqing administration. To evaluate the therapeutic effect of Naoxinqing on NAFLD induced by a high-fat diet,biochemical and histopathological experiments were performed,including assessment of blood lipids,liver function,serum inflammatory factors,as well as Hematoxylin and eosin (HE),Oil red O,and Sirius red staining of liver. Subsequently,network pharmacology and molecular docking techniques were employed to predict the key targets of Naoxinqing. Finally,the mechanism of Naoxinqing was validated by Western Blot in HepG2 cells and liver tissue. Results The results of serum biochemistry and liver tissue pathology showed that Naoxinqing can significantly improve high-fat diet-induced hepatic lipid accumulation,hepatocellular injury,and inflammation. Network pharmacology and molecular docking analysis results suggested that Naoxinqing may affect lipid metabolism through the AMP-activated protein kinase (AMPK)/Sirtuin 1 (SIRT1) pathway. Finally,in vitro cell experiment confirmed that the main mechanism of Naoxinqing is to activative the AMPK/SIRT1 pathway,upregulate the expression of downstream carnitine palmitoyltransferase 1 (CPT1A),promote fatty acid oxidation,and ultimately improve NAFLD. Conclusion This study demonstrated that Naoxinqing improved NAFLD by promoting fatty acid oxidation through the activation of the AMPK/SIRT1 pathway.

OBJECTIVE To explore the role and mechanism of dental pulp stem cells(DPSCs)in repairing hypoxic injury to rats pulmonary microvascular endothelial cells(PMVECs).METHODS ①PMVECs were treated with cobalt chloride at 0,10,25,50 and 100 μmol·L-1 for 72 h.CCK-8 was used to detect the cell viability,and the protein levels of hypoxia-inducible factor 1α(HIF-1α),zona occludens small-band protein 1(ZO-1),and occludin(OCLN)were detected by Western blotting.②There was a cell control group,model group,and model+DPSCs group,and the levels of reactive oxygen species(ROS)was detected by immunofluorescence staining after at 24 and 48 h of action.The levels of ZO-1 and OCLN proteins were detected by Western blotting.③ A cell control group,model group,model+DPSC group and model+DPSC cell knockdown superoxide dismutase 1(SOD1)group were set up.The mRNA level of SOD1 was detected by real-time fluorescence quantitative PCR 24 and 48 h later,while the protein levels of ZO-1 and OCLN were detected by Western blotting.RESULTS ① Com-pared with the cell control group,72 h of cobalt chloride 100 μmol·L-1 treatment of PMVECs resulted in a cell survival rate above 80%,a significant increase in the level of HIF-1α protein(P<0.05),a signifi-cant decrease in the levels of ZO-1 and OCLN proteins(P<0.01),and establishment of a model of hypoxic injury in PMVECs.② Compared with the cell control group,the ROS level was significantly higher in the model group(P<0.01).Compared with the model group,the ROS level was significantly lower in the model+DPSCs group(P<0.01),while the levels of ZO-1 and OCLN proteins were signifi-cantly higher in the model+DPSCs group(P<0.05).③ Compared with the DPSC group,ZO-1 and OCLN expressions were significantly decreased after knockdown of SOD1 in DPSCs(P<0.05,P<0.01).CONCLUSIONS DPSCs can repair hypoxic injury to PMVECs,and the anti-oxidative stress capacity of DPSCs plays an important role in hypoxic injury repair of PMVECs.
