摘要:

摘要: 目的 探讨青蒿琥酯(Art) 对高糖诱导的大鼠肾小管上皮细胞(NRK-52E) 的凋亡及肿瘤坏死因子-α (TNF-α)、白细胞介素-8(IL-8)表达的影响。 方法 传代培养大鼠肾小管上皮细胞, 分为正常对照组、高糖组、高糖+不同浓度青蒿琥酯组(10、20、30 mg/L)、高糖+依那普利对照组(5 mg/L)。 四甲基偶氮唑盐微量比色(MTT)法观察细胞增殖能力的改变; 流式细胞仪 AnnexinV-FITC/PI 双染法检测细胞凋亡指数; 酶联免疫吸附(ELISA)法检测细
胞培养上清液中 TNF-α和 IL-8 蛋白含量。 结果 (1)经高糖处理 48 h 后, NRK-52E 细胞增殖抑制, 细胞凋亡率增高, 细胞上清液中 TNF-α、IL-8 蛋白浓度升高。(2)经青蒿琥酯干预后, 与高糖组比较, NRK-52 细胞增殖明显, 细胞凋亡率减低, 细胞上清液中 TNF-α、IL-8 蛋白浓度降低, 其干预作用呈现剂量依赖性。 结论 青蒿琥酯可抑制高糖诱导的 NRK-52E 细胞凋亡及细胞上清液中炎症因子 TNF-α、IL-8 的表达。 青蒿琥酯的抗炎和免疫调节作用可能有助于糖尿病肾病的治疗。

Abstract:

Abstract:Objective To investigate the effects of artesunate (Art) on cell apoptosis, tumor necrosis factor-alpha (TNF- α) and interleukin-8 (IL-8) expression induced by high glucose in rat renal tubular epithelial cells (NRK-52E). Methods NRK-52E cells were cultured and divided into normal control group, high glucose group, high glucose with different concentrations of Art (10 mg/L, 20 mg/L and 30 mg/L) groups, and high glucose with Ena (5 mg/L) group. MTT assay was used to detect the cell proliferation. The apoptotic rate was evaluated by flow cytometry with AnnexinV-FITC/PI double stains. The protein levels of TNF-α and IL-8 in the cell culture supernatant were determined using ELISA. Results High glucose inhibited NRK-52E proliferation, induced its apoptosis, and the expressions of TNF-α and IL-8 in the supernatant. Application of Art obviously abolished the effects of high glucose, and the effects of Art were showed in dose-dependent manner. Conclusion Art can suppress high glucose-stimulated cell apoptosis, enhance TNF-α and IL-8 expression in NRK-52E cells. The anti-inflammatory action and immune regulation of Art could be a novel approach of treating diabetic nephropathy.
