Abstract: The objective of the current study was to explore the anti-inflammatory mechanism of Shenfukang granule on chicken kidney swelling. Ninety healthy chickens were divided into blank group (n=15) and test group (n=75), the test group was replicated by the chicken kidney swelling model through feeding high-calcium and high-protein diet. After successful modeling, the test group was randomly divided into model group, positive drug group, Shenfukang high, medium and low dose group (n=15), Shenfukang granule 2.0, 1.0 and 0.5 g·L-1, positive drug group, drinking water to Canglan oral liquid 1.0 mL·L-1, The drinking water of the model group was given 1.0 mL·L-1 of normal saline for 2 times·d-1 and 5 days. Subpteral venous blood was collected before modeling, after modeling and 2 days after the last administration to isolate the serum. The content changes of serum IL-1, TNF-α, MCP-1 and TGF-β1 content were detected by ELISA. RT-PCR was used to detect renal IL-1R, IκBα, NF-κB mRNA transcription. Results were as follows: Compared with the blank group, the serum contents of IL-1, TNF-1, MCP-1 and TGF-β1 were significantly increased in the model group (P<0.05), the transcription of IL-1R, NF-κBp65 mRNA in kidney was significantly increased (P<0.01), and IκBα mRNA in kidney was significantly decreased (P<0.01). After drinking water treatment, the serum IL-1, TNF-α, MCP-1 and TGF-β1 contents of Shenfukang granule were significantly decreased in the high and low dose group and the positive drug group (P<0.01). The results of the current study suggested that Shenfukang granule played an anti-inflammatory role in inhibiting the IL-1R/NF-κB signaling pathway by reducing the contents of IL-1, TNF-α, MCP-1 and TGF-β1 in serum of kidney swelling chicken.
