Objective:To explore the effect of Simo decoction improving the low duodenal inflammation and protecting the du-odenal mucosal barrier in rats with functional dyspepsia(FD).Methods:Sixty SD rats were randomly divided into control group(10 rats)and model group(50 rats),and the modeling rats were prepared by multivariate intervention method.After successful modeling,the modeling rats were randomly divided into model group,Simo decoction high-dose,medium-dose,low-dose group and mosapride group,with 10 rats in each group.The high-dose,medium-dose,and low-dose groups of Simo decoction were ga-vage given 5.62 g/kg,2.81 g/kg,and 1.40 g/kg,respectively,and the mosapride group was gavage given 0.305 mg/kg of mosapride,and the control group and model group were gavage given the same amount of distilled water for 14 days.The body weight of rats was observed;gastric emptying rate and small bowel propulsion rate were measured;transmission electron microscopy was used to observe the morphology of duodenal epithelial cells;ELISA detected serum levels of IL-17A and IL-22;Western blot and immunohistochemis-try were used to detect the expressions of protease-activated receptor 2(PAR-2)and tight junction protein(ZO-1,claudin-1)in the duodenum.Results:Compared with the control group,the body weight,gastric emptying rate and small intestinal propulsion rate of the model group were significantly reduced(P<0.01),transmission electron microscopy showed widening of the duodenal epithelial cell space,serum IL-17A and IL-22 levels were significantly increased(P<0.01),the expression of PAR-2 in duodenal tissue was in-creased,and the expressions of ZO-1 and claudin-1 were downregulated(P<0.01).Compared with model group,the gastric emptying rate and small intestinal propulsion rate in Simo decoction high-dose,medium-dose and mosapride group were increased(P<0.05,P<0.01),the contents of IL-17A and IL-22 in serum decreased(P<0.05,P<0.01),and the expression of PAR-2 in duodenal tissues was down-regulated,the expressions of ZO-1 and claudin-1 was significantly increased(P<0.01).The low-dose group of Simo soup could improve weight loss(P<0.01),reduce IL-17A content and PAR-2 expression,and increase ZO-1 and claudin-1 expression(P<0.05,P<0.01),while the effect on other indexes was not obvious.Conclusion:Simo decoction may reduce low-grade duodenal in-flammation to repair the mucosal barrier by down-regulating the levels of IL-17A and IL-22 and the expression of PAR-2,and up-regu-lating the expression of ZO-1 and claudin-1,so as to exert the effect of FD treatment.

Objective:
To investigate the relationship between tropomodulin 3(TMOD3) and the malignant biological characteristics of hepatocellular carcinoma, and the predictive potential of TMOD3 as a biomarker for the recurrence and metastasis of hepatocellular carcinoma.
Methods:
Firstly, the structure of TMOD3 and its subcellular localization in cells and tissues were analyzed using database of Human Protein Atlas. Then explored the differential expression of TMOD3 in hepatocellular carcinoma tissues and normal liver tissues and its impact on clinical pathological characteristics and prognosis using TCGA and GEO datasets. Subsequently, the STRING database was utilized to explore the interacting proteins of TMOD3, followed by enrichment analysis conducted using the Metascape database. Finally, Logistic regression was used to analyze the independent risk factors for metastasis of hepatocellular carcinoma and evaluated the importance of predictive variables using ROC curves and Wald tests. Survival analysis was conducted using the Kaplan-Meier curve and the Log-rank test.
Results:
TMOD3 was localized to actin filaments in cells, and compared with normal tissues, the expression level of TMOD3 in liver cancer tissues is higher(P<0.05), and high expression of TMOD3 was closely related to lymph node metastasis and distant metastasis of hepatocellular carcinoma patients(P<0.05). Enrichment analysis results revealed that TMOD3 and its interacting proteins mainly function and signaling pathways related to tumor invasion and migration. Logistic regression found that TMOD3 was an independent risk factor for recurrence and metastasis of hepatocellular carcinoma(OR: 4.359, 95%CI: 1.235-15.384,P=0.022). Survival analysis revealed that high expression of TMOD3 was associated with poor OS, DFS, and RFS of hepatocellular carcinoma patients(P<0.05). Both ROC analysis and Wald test indicated that TMOD3 has good predictive characteristics for recurrence and metastasis of hepatocellular carcinoma.
Conclusion
TMOD3 is closely associated with the invasion and metastasis of hepatocellular carcinoma and is an independent risk factor for the recurrence and metastasis of liver cancer. TMOD3 performs well in predicting the recurrence and metastasis of hepatocellular carcinoma and has the potential to become a biomarker for predicting the recurrence and metastasis of hepatocellular carcinoma.

Objective To investigate the effects of Jianpi Yichang Powder on regulating the NLRP3 inflammasome signaling pathway to inhibit dendritic cells(DCs)inflammatory injury induced by TNF-α;To explore its mechanism in the treatment of ulcerative colitis.Methods C57BL/6 mice DCs were primitively isolated and cultured.The cultured DCs were randomly divided into the normal group,model group,negative control group,positive drug group and TCM group.DCs inflammatory microenvironment model was established by TNF-α induction.After corresponding treatments were given to each group,CCK-8 method was used to detect cell proliferation ability,immunofluorescence and Western blot were used to detect the protein expressions of NLRP3,ASC and Caspase-1 in DCs respectively,Western blot and RT-PCR were used to detect the protein and mRNA expressions of IL-1β and IL-18 in DCs.Results Compared with the normal group,the proliferation ability in DCs of model group significantly decreased(P<0.01),the positive expressions of NLRP3,ASC and Caspase-1 significantly increased,the expressions of NLRP3,ASC,Caspase-1,IL-18,IL-1β protein and IL-18,IL-1β mRNA in DCs significantly increased(P<0.01).Compared with the model group and negative control group,the proliferation ability of DCs significantly increased in positive drug group and TCM group(P<0.01),the positive expressions of NLRP3,ASC,and Caspase-1 significantly decreased(P<0.01),the protein expressions of NLRP3,ASC,Caspase-1,IL-1β and IL-18 significantly decreased(P<0.05,P<0.01),and the mRNA expressions of IL-1β and IL-18 significantly decreased(P<0.01).The cell proliferation ability,Caspase-1 positive expression,and IL-18 mRNA expression of TCM group were significantly higher than those of the positive drug group(P<0.05),while the mRNA expression of IL-1β was lower than that of the positive drug group(P<0.05).Conclusion Jianpi Yichang Powder can inhibit the inflammatory response of DCs induced by TNF-α,and its mechanism in the treatment of ulcerative colitis may be related to regulating the expressions of the NLRP3 inflammasome signaling pathway,including the expressions of NLRP3,ASC,Caspase-1,IL-18 and IL-1β.
