摘要Background:Inflammation,caused by prolonged hyperglycemia,plays a substantially more important part in the progression of diabetic peripheral neuropathy(DPN).Notably,the MAPK pathway that mediates the Nuclear Factor-kappa B(NF-κB)pathway contributes to inflammation-induced peripheral nerve damage,affecting cell survival.Juan Bi Tong Luo(JBTL),a traditional Chinese medicine(TCM),has demonstrated favorable results in alleviating pain and numbness in patients with DPN;however,whether JBTL exerts its effect through the MAPK mediating NF-κB pathway remains unclear.Methods:This study investigated whether JBTL modulates apoptosis in DPN models and Schwann cells cultured in 100 mM of glucose by MAPK/NF-κB.Results:The JBTL altered inflammation,reduced peripheral nerve tissue damage,and improved cell survival rates by down-regulating MAPK/NF-κB.Conclusion:Our findings demonstrate that the effect of JBTL on DPN is likely mediated by suppressing inflammation induced by the MAPK/NF-κB pathway,thus providing evidence for the clinical efficacy of JBTL in treating DPN.
