Abstract
Objective
2
To study the effect of Huangqi Guizhi Wuwutang on receptor of advanced glycation end products(AGEs)/advanced glycation endproducts (RAGE)/nuclear transcription factor-kappa B p65 (NF-
κ
B p65) signaling pathway in the diabetic peripheral neuropathy rats through an animal modeling experiment
and discuss the mechanism of Huangqi Guizhi Wuwutang in alleviating diabetic peripheral neuropathy.
Method
2
Rat model of diabetic peripheral neuropathy was established by high-fat diet and intraperitoneal injection with streptozotocin (STZ). After successful modeling
Huangqi Guizhi Wuwutang intervention began in the fifth week. The patients in high-dose group (19.40 g∙kg
-1
∙d
-1
)
middle-dose group (4.85 g∙kg
-1
∙d
-1
) and low-dose group (2.43 g∙kg
-1
∙d
-1
) were given by gavage continuously for 12 weeks. The western medicine control group was given 25 mg∙kg
-1
∙d
-1
by gavage. After the experiment
serum interleukin-1
β
(IL-1
β
) and tumor necrosis factor-
α
(TNF-
α
) were detected by enzyme-linked immunosorbent assay (ELISA). Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) was used to detect RAGE and NF-
κ
B p65 mRNA expressions in sciatic nerve tissue. The expressions of RAGE
NF-
κ
B and phosphorylation(p)-NF-
κ
B p65 proteins in sciatic nerve tissues were detected by Western blot (WB).

B p65 to NF-
κ
B p65 was increased
and the phosphorylation of NF-
κ

0.01). After the intervention of Huangqi Guizhi Wuwutang
compared with the model group

B p65 was decreased in high-dose group (
P

Conclusion
2
Huangqi Guizhi Wuwutang can alleviate diabetic peripheral neuropathy
and its mechanism may be related to blocking the expression of RAGE on tissue cell surface in AGEs/RAGE/NF-
κ
B signaling pathway
inhibiting the activation of NF-
κ
B and inducing TNF-
α
triggered oxidative stress and excessive inflammatory response
