Abstract:
Objective:To observe the effect of Shenling Baizhusan on the protein and mRNA expression of inhibitor of nuclear factor kappa B kinase (IκK)/inhibitor of nuclear factor kappa B(IκB)/nuclear factor kappa B(NF-κB) signaling pathway in the colon of rats with ulcerative colitis (UC) of spleen deficiency and dampness stagnation type, and to explore the mechanism of Shenling Baizhusan in the treatment of UC. Method:The 48 Wistar rats were randomly divided into normal group, model group, Shenling Baizhusan group (15.6 g·kg-1) and osalazine sodium group (0.68 g·kg-1), 12 rats in each group. The model of UC with spleen deficiency and dampness stagnation was reproduced by trinitrobenzene sulfonic acid (TNBS)/ethanol enema combined with environment and diet intervention.Serum levels of tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β(IL-1β) were determined by enzyme-linked immunosorbent assay（ELISA）. The expression of NF-κB p65, IκBα, IκKβ protein in colon tissue was measured by Western blot and immunohistochemical method, and the mRNA expression of NF-κB p65, IκBα and IκKβ in colon tissue of rats in each group was detected and compared by real time polymerase chain reaction (Real-time PCR). Result:Compared with normal group,the levels of TNF-α,IL-6 and IL-1β in the serum, the protein and mRNA expression of NF-κB p65, IκKβ in colon tissue of the model group was significantly higher than that of normal group (P<0.01), and the protein and mRNA expression of IκBα was significantly lower than that of normal group (P<0.01). Compared with model group,the protein and mRNA expression of NF-κB p65, IκKβ in colon tissue of the Shenling Baizhusan group and osalazine sodium group were significantly decreased (P<0.01), and the protein and mRNA expression of IκBα was significantly increased (P<0.01). Conclusion:Shenling Baizhusan can obviously down regulate the protein and mRNA expression of NF-κB p65, IκKβ,up regulate the expression of IκBα in colon tissue of UC rats with spleen deficiency and dampness stagnation. The inhibition of IκK/IκB/NF-κB signal pathway activation by Shenling Baizhusan is an important mechanism of its role in protecting intestinal mucosa.
