collagen(COLIV),and the proliferation of human glomerular mesangial cells(GMC)induced by high glucose and high fat in vitro,and to inhibit the proliferation of human glomerular mesangial cells(GMC)MRNA and protein levels,and down-regulate the expression of advanced glycation end products(AGEs).It is suggested that the combination of active and detoxifying traditional Chinese medicine can inhibit the glomerular arteriosclerosis by inhibiting GMC extracellular matrix and AGES synthesis.2.The expression of TGF-β1,MCP-1 and NF-κB in GMC cells can inhibit the expression of PPAR-γ in GMC cells.It is suggested that the compatibility of traditional Chinese medicine components can play a role in preventing and treating DN by regulating the expression of related cytokines and signaling pathways.3.The possible combination of the active ingredients of active and active Chinese medicine may protect the damaged GMC by inhibiting the expression of MCP-1,FN,COLIV and AGEs up-regulated the expression of PPAR-γ by inhibiting the TGF-β1 / NF-κB signaling pathway To slow the progress of DN disease,to protect the role of damaged kidneys.4.The best compatibility formula for the compatibility of traditional Chinese medicine is Berberine Hydrochloride(Low Dose 20μM)Astragaloside(Low Dose 20μM)Hirudin(Low Dose 0.5μM)Luteolin(high dose of 540μM). |
