Methods: Twenty children undergoing cardiac operation with CPB were selected in the study. Plasma concentrations of endotoxin, soluble intercellular adhesion molecule 1, tumor necrosis factor α, and urinary microalbumin were measured after anesthetic induction (baseline), bypass for 20 minutes, at the end of CPB, and at 2, 4, and 18 h after the end of CPB. Results: The plasma concentrations of endotoxin, soluble intercellular adhesion molecule 1, and urinary microalbumin began to increase at 2 h after the end of CPB, and remained higher than that of the baseline, while the concentration of tumor necrosis factor α increased only at the end CPB and at 2 h after the end of CPB. Conclusion: Cardiopulmonary bypass can induce inflammatory response, resulting in the activation or injury of vascular endothelial cells, and can increase the vascular permeability.展开更多

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
