英文摘要: This study is based on the early clinical and libratory research. It uses STZ to create diabetic peripheral neuropathy rat model. The study aims at miRNA- - this newest basic core mechanism of DPN and use the gene chip technology to observe the effect of Tangluoning to miRNA-146a、miRNA-25、miRNA-132、miRNA-28、miRNA-200a、miRNA-144、miRNA-192,miRNA-216a /217 of diabetic rat sciatic nerve. It also observes the effect of Tangluoning to NF-κB signaling pathway, PKR signaling pathway, MAPKs signaling pathway, TLRs signaling pathway, Nox4 signaling pathway, FoxO3a signaling pathway, PI3K/Akt signaling pathway and Wnt/β-catenin signaling pathway of diabetic rat sciatic nerve. The study wants to explore the mechanism of Tangluoning from bottom gene cell and molecular level and provide scientic evidence of Chinese Medicine treating DPN. We are looking forward the target or way of Chinese Medicine treating DPN and lay the foundation for the new treating-DPN drug exploitation.
