Thiazolyl Blue Tetrazolium Bromide assay were used to detect cell viability. DLactate, diamine oxidase and myeloperoxidase and cytokines were determined by enzyme-linked immunosorbent assay. Western blot was used to detect apoptosis-related proteins and tight junction(TJ) proteins. Real-time quantitative polymerase chain reaction was used to quantify the levels of m RNA expression of cytokines. Histological analysis was performed by hematoxylin and eosin staining. An immunofluorescence staining assay was performed to determine the expression level of TJ protein. RESULTS: YJSB increased cell viability and decreased apoptosis, maintained intestinal permeability after LPSinduced. YJSB inhibited LPS-induced decrease of TJ protein expression, pro-inflammatory cytokine levels and neutrophil infiltration. CONCLUSION: YJSB protect against LPS-induced intestinal barrier dysfunction via anti-inflammatory and anti-apoptosis, suggesting its therapeutic potential against intestinal barrier injury-related diseases.展开更多
