Abstract:
Objective To establish a rat chronic atrophic gastritis with dysplasia model and observe the effect of Shidan granules on the positive expression of NF-κB p65 in gastric tissues and the extent of IKKβprotein content in gastric tissues of chronic atrophic gastritis with dysplasia model rats. Methods Seventy SPF male Wistar rats were randomly divided into the blank group and 60 into the model group. In addition to the blank group, the modeling group was made using the MNNG-based comprehensive modeling method (150 μg/ml MNNG 5 ml/kg each stomach, containing 0.03％ ranitidine feed, free drinking 0.1％ ammonia), and then model successed at the 28th week. The remaining rats in the modeling group were randomly divided into 5 groups: the model group with intragastric administration of gavage, the western medicine group with intragastric administration of viralin, the Shidan granules group with intragastric administration of low/medium/high concentration Chinese medicine decoction. After 12 weeks of treatment, they were sacrificed and the expression of NF-κB p65 and IKKβ was measured and compared. Results Compared with the model group, the average optical density of NF-κBp65 (0.387 ± 0.011, 0.252 ± 0.022, 0.193 ± 0.003 vs. 0.442 ± 0.035) and the expression level of IKKβ (0.309 ± 0.056, 0.216 ± 0.025, 0.125 ± 0.016 vs. 0.405 ± 0.042) in the low-, middle- and high-dose Shidan granules groups significantly decreased (all Ps<0.01). Conclusions The mechanism of improving the precancerous lesions of gastric cancer by Shidan granules may be achieved by inhibiting the expression of IKK, reducing the abnormal activation of NF-κB.
