Methods Twenty-eight patients with type Ⅱ diabetes(T2D) were undergone pulsed electromagnetic fields(PEMF) stimulation at the acupoints of Píshū(脾俞 BL 20), Zúsānl(足三里 ST 36), Shènshū(肾俞 BL 23) and Yíshū(胰俞, EX-B3) for a period of 4 weeks. Urinary micro-albumin(U-m Alb) excretion, plasma methane dicarboxylic aldehyde(MDA and lipopolysaccharide(LPS) of the patients were used for evaluating therapeutic efficacies. Results After the acumagnetotherapy, U-m Alb excretion in the participated patients was markedly reduced(27.21±3.51 vs 8.51±0.95, P0.001) accompanied with decreased MDA(16.46±1.17 vs 12.40±1.86, P0.05) and LPS(37.41±3.84 vs 21.63±3.61, P0.05) levels in plasma while the metabolic control of these patients was not significantly altered. Acumagnetotherapy increased IκBα content(0.69±1.17 vs 1.30±0.29, P0.01), an inhibitory protein of inflammatory response, and correspondingly reduced the protein levels of inflammatory activating proteins, NF-κB p65(0.98±0.42 vs 0.43±0.28, P0.05) and NF-κB p50(1.19±0.40 vs 0.76±0.30, P0.05). The acumagnetotherapy also inhibited the oxidantproducing enzyme, Nox4 protein expression(1.32±0.40 vs 0.37±0.23, P0.05) in patient 's blood lymphocytes. Conclusion Short-term intervention of acumagnetotherapy in patients with T2 D mitigates DKD progress potentially by its anti-oxidative and anti-inflammatory effects.展开更多
