摘要
Along with the development of economy and society, type 2 diabetic mellitus(T2DM) has become one of the most common diseases at the global level. As one of the complications of T2 DM, diabetic neuropathic pain(DNP) stubbornly and chronically affects the health and life of human beings. In the pain field, dorsal root ganglion(DRG) is generally considered as the first stage of the sensory pathway where the hyperexcitability of injured neurons is associated with different kinds of peripheral neuropathic pains. The abnormal electrophysiology is mainly due to the changed properties of voltage-gated sodium channels(VGSCs) and the increased sodium currents(INa). Curcumin is an active ingredient extracted from turmeric and has been demonstrated to ameliorate T2 DM and its various complications including DNP effectively. The present study demonstrates that the INa of small-sized DRG neurons are significantly increased with the abnormal electrophysiological characteristics of VGSCs in type 2 diabetic neuropathic pain rats. And these abnormalities can be ameliorated efficaciously by a period of treatment with curcumin.
