摘要:
二甲基姜黄素是姜黄素的一种结构衍生物,具有抗炎抗肿瘤作用,具有缓释作用的新剂型脂质体二甲基姜黄素(Lipo-DiMC)有较好的生物利用度和代谢稳定性。淋巴细胞的过度增殖、细胞周期紊乱和细胞凋亡异常是类风湿疾病的病理特征。采用薄膜法制备小粒径(0.2 μm)的Lipo-DiMC、建立胶原诱导的关节炎(CIA)大鼠模型(正常组,CIA模型组和CIA+Lipo-DiMC治疗组)和体外细胞模型,探讨Lipo-DiMC对大鼠脾淋巴细胞增殖和淋巴细胞周期的影响。Lipo-DiMC关节腔注射治疗CIA大鼠(120 μg/mL,每3 d关节腔注射治疗一次,每次400 μL,共治疗6次)。在CIA发病进程中和Lipo-DiMC治疗过程中,对关节炎严重程度进行生理评估和指数评分; 血常规检测外周血中各免疫细胞数量的变化。新鲜提取的大鼠脾淋巴细胞建立体外细胞模型,MTT法检测Lipo-DiMC对大鼠脾淋巴细胞增殖作用,细胞流式仪检测Lipo-DiMC对脾淋巴细胞周期作用。实验结果显示Lipo-DiMC在体内和体外均对大鼠脾淋巴细胞的细胞周期有调节作用。
Abstract:
Dimethyl curcumin(DiMC)is one analogue of curcumin with anti-inflammatory property. Liposome dimethyl curcumin(Lipo-DiMC)has improved bioavailability, metabolic-stability and slow-release compared with DiMC. The excessive lymphocyte proliferation is one of characteristic of Rheumatoid arthritis(RA). The study is to investigate the effects of Lipo-DiMC on proliferation and cell cycle of rat spleen lymphocytes. Lipo-DiMC(particle size 0.2 μm)was prepared by a thin film method. Collagen-induced arthritis(CIA)rat model was established(normal group, CIA model group and CIA+Lipo-DiMC treatment group)successfully. CIA rats were treated with Lipo-DiMC by intra-articular injection(120 μg/mL, treated once every 3 d, 400 μL each time, 6 treatments in total). Physiological assessment and index scores of arthritis severity were monitored over the CIA process and treatments; the dynamic change of cells number in peripheral blood of CIA rats and Lipo-DiMC treated rats were recorded by Routine blood test. In vivo cell cycle of spleen lymphocytes of normal, CIA and Lipo-DiMC treated CIA rats were detected by flow cytometry(PI staining). Freshly extracted rat spleen lymphocytes were used to established cell model to study the anti-proliferative and cell cycle regulatory effects of Lipo-DiMC in vitro. MTT assay was used to detect the proliferation rate of rat spleen lymphocytes with or without Lipo-DiMC added. Cell flow cytometry was used to detect the effect of Lipo-DiMC on cell cycle of spleen lymphocyte in vitro. Experiments showed that Lipo-DiMC demonstrated a regulatory effect on cell cycle of rat spleen lymphocyte in vitro and in vivo.
