目的探讨维持性血液透析患者炎症状态与瘙痒的关系。方法 39例维持性血液透析患者及12例正常人入选本研究。按照直观类比标度(visual analog scale,VAS)评分系统对病例组瘙痒程度进行询问。病例组分别抽取问询期内同次透析前后血标本,...目的探讨维持性血液透析患者炎症状态与瘙痒的关系。方法 39例维持性血液透析患者及12例正常人入选本研究。按照直观类比标度(visual analog scale,VAS)评分系统对病例组瘙痒程度进行询问。病例组分别抽取问询期内同次透析前后血标本,对照组标本来自华中科技大学同济医学院附属同济医院健康体检人群。采用流式细胞仪的液相蛋白定量技术检测炎症因子:白介素(interleukin,IL)-2、IL-6、IL-10、肿瘤坏死因子(tumor necrosis factor,TNF)。结果 Spearman相关分析及线性回归显示透析前IL-2与VAS评分呈正相关(β=0.586,t=4.399,F=19.354P<0.01)。病例组按VAS得分分为3组,无瘙痒者(VAS=0)占38%,轻至中度瘙痒者(VAS=1~5)占41%,重度瘙痒者(VAS>5)占21%;重度瘙痒组透析前后IL-2显著高于无瘙痒组。结论维持性血液透析患者中瘙痒的发生率较高。炎症状态在瘙痒的发病机制中有重要作用。IL-2水平影响维持性血液透析患者的瘙痒状态。展开更多

It has also been demonstrated to have important cytoprotective functions during oxidative stress. The present study aimed to examine the cytoprotective effect of BV on NRK-52 E cells, a proximal tubular cell line derived from rat kidney. Cells were treated with 50 μmol/L cisplatin for 24 h(cisplatin group) or pre-treated with BV for 30 min, then with 50 μmol/L cisplatin for 24 h(cisplatin+BV group). Those given no treatment served as a control. Cell apoptosis was evaluated by flow cytometry and cell viability by Cell Counting Kit-8(CCK-8). The protein expressions of cleaved caspase3, Bax and Bcl-2 were assessed by Western blotting. Reactive oxygen species(ROS) levels were measured using carboxydichlorodihydrofluorescein diacetate(H2DCF). The results showed that cisplatin induced the apoptosis of NRK-52 E cells, decreased cell viability, and increased the formation of ROS by upregulating the expression of cleaved caspase3 and Bax and decreasing Bcl-2 protein expression. These effects could be significantly reversed by pretreatment with BV. It was concluded that BV can protect against cisplatin-induced cell apoptosis through the anti-oxidative effects.展开更多
