Objective: To investigate the effect of Yiqi Yangyin Huazhuo Tongluo recipe(YQYYHZTLR) on plasma transforming growth factor beta1(TGF-β1)
matrix metalloproteinase-9(MMP-9)
tissue inhibitor of metalloproteinase-1(TIMP-1) in patients with early diabetic nephropathy(DN).Method: Sixty-three patients with DN were randomly divided into the control group(n=31) and the treatment group(n=32).The control group was applied DN regular treatment and the treatment group was added to YQYYHZTLR on the basis of regular treatment.Both of them were treated for three months.Plasma TGF-β1
MMP-9
and TIMP-1 were determined with ELISA in two groups both before and after treatment.β2-microglobulin(β2-MG)and urinary albumin excretion rate(UAER) were also examined.Result: Plasma levels of TGF-β1and TIMP-1 between the two groups were significantly lower than those of pretreatment(P<0.05
P<0.01).Plasma levels of MMP-9 and MMP/TIMP-1 rate between the two groups were significantly higher than those of pretreatment(P<0.05
P<0.01).Favorable changes of levels of other parameters(β2-MG and UAER) were also demonstrated(P<0.05
P<0.01).At the same time
plasma levels of TGF-β1
MMP-9 and TIMP-1 were different significantly in the treatment group after treatment compared to the control group(P<0.05
P<0.01).Conclusion: YQYYHZTLR has a strong influence on regulation and control of extracellular matrix(ECM) metabolism to delay the development of early DN by improving plasma levels of TGF-β1
