[摘要] 目的 研究雷公藤多甙片(TG)對狼疮性肾炎外周血单个核细胞(PBMCs)多药耐药蛋白表达的影响。方法 选择2015年11月~2017年5月我院收治的58例LN患者为研究对象,分为接受TG治疗的TG组(29例)和接受常规激素治疗的对照组(29例),分别提取两组治疗前后PBMCs,采用反转录-聚合酶链反应(RT-PCR)法检测TG对PBMCs多药耐药相关蛋白蛋白(MRP)和多药耐药相关基因(MDR1)和P-糖蛋白170(P-gp 170)表达的影响。结果 治疗3个月后,两组PBMCs MRP、MDR1 mRNA相对表达量均明显提高(P<0.05),且TG组PBMCs MRP、MDR1 mRNA相对表达量显著高于对照组(P<0.05);两组PBMCs P-gp 170阳性表达率均明显提高(P<0.05),且TG组PBMCs P-gp 170阳性表达率显著高于对照组(P<0.05)。 结论 TG可有效提高LN患者PBMCs MRP、MDR1及P-gp 170表达,提高患者免疫力,改善预后,LN患者治疗中应检测多药耐药蛋白表达水平以确定其耐药性。

[Abstract] Objective To study the effect of tripterygium glycosides (TG) on the expression of multidrug resistance proteins in peripheral blood mononuclear cells (PBMCs) of patients with lupus nephritis (LN). Methods A total of 58 patients with LN treated in our hospital from November 2015 to May 2017 were selected as study subjects and divided into TG group (treated with TG,29 cases) and the control group (given routine hormonotherapy,29 cases).PBMCs of the two groups were extracted before and after treatment, and reverse transcription polymerase chain reaction (RT-PCR) was used to detect the effects of TG on the expression of multidrug resistance associated protein (MRP),multidrug resistance associated genes (MDR1) and P-glycoprotein 170 (P-gp 170) in PBMCs. Results After 3 months of treatment,the relative expression levels of PBMCs,MRP and MDR1 mRNA in two groups were significantly increased (P<0.05),and TG group,MDR1 mRNA expression was significantly higher than the control group (P<0.05) the relative expression of PBMCs MRP and MDR1 mRNA in of TG group was significantly higher than that in the control group (P<0.05).The positive expression rates of PBMCs P-gp 170 in two groups were significantly increased (P<0.05),and the positive rate of PBMCs P-gp 170 expression in the TG group was significantly higher than that in the control group (P<0.05). Conclusion TG can effectively improve the expression of PBMCs,MRP,MDR1 and P-gp 170 in patients with LN,improve the immunity of patients and improve the prognosis.The expression level of multidrug resistance protein should be detected in patients with LN in order to determine their drug resistance.endprint

狼疮性肾炎(lupus nephritis,LN)是继發于系统性红斑狼疮(SLE)最常见的严重疾病,其发病率高达60%,且存在肾脏病变,严重影响患者的生存率[1]。为阻止LN的进展和复发,保护患者肾功能,临床主要的治疗方法为免疫抑制治疗的糖皮质激素(GC)治疗,但复发率高、费用高,且存在副作用[2]。雷公藤多甙片(tripterygium glycosides,TG)是具有较强抗炎和免疫抑制作用的雷公藤提取物制成的片剂,对LN的疗效较好[3]。本研究选取2015年11月 ~ 2017年5月我院收治的58例LN患者为研究对象,探讨TG对LN患者外周血单个核细胞多药耐药蛋白表达的影响。
