        摘  要   目的:研究人参根提取物对小鼠脾淋巴细胞自噬、增殖及细胞因子分泌的影响,并研究其作用机制。方法:将小鼠脾淋巴
        细胞分为空白对照组、阳性对照组(刀豆蛋白A,5 μg/mL)和不同质量浓度人参根提取物组(32、125、500 μg/mL,以冻干粉末计)。
        各组细胞加入相应药物培养48 h后,分别采用吖啶橙染色法检测细胞的自噬情况;采用CCK-8法检测细胞的增殖情况;采用酶联
        免疫吸附法测定细胞培养液中白细胞介素4(IL-4)、IL-6、肿瘤坏死因子α(TNF-α)的水平;采用Western blotting法检测细胞中微管
        相关蛋白轻链β 3 (LC3B)、酵母ATG6同源物(Beclin-1)的表达水平以及腺苷酸活化蛋白激酶(AMPK)、蛋白激酶B(AKT)、雷帕霉
        素靶蛋白(mTOR)的磷酸化水平。结果:与空白对照组比较,32、125、500 μg/mL人参根提取物均能够增加小鼠脾淋巴细胞酸性自
        噬体的数量(P<0.05或P<0.01);125、500 μg/mL人参根提取物均可显著提高细胞存活率,显著提高细胞中IL-4、IL-6和TNF-α的
        水平,显著促进细胞中LC3BⅠ向LC3BⅡ转化,显著上调细胞中Beclin-1蛋白表达水平,显著提高AMPK蛋白的磷酸化水平,显著
        降低AKT和mTOR蛋白的磷酸化水平,差异均有统计学意义(P<0.05或P<0.01)。结论:人参根提取物能通过激活AMPK、抑制
        AKT活化来抑制mTOR活性,从而诱导小鼠脾淋巴细胞发生自噬、激活脾淋巴细胞活性、调节细胞因子分泌以发挥免疫增强作用。

        ABSTRACT    OBJECTIVE:To study the effects of ginseng root extract on autophagy,proliferation and cytokine of splenic
        lymphocyte of mice,and to study its mechanism. METHODS:The splenic lymphocyte of mice were divided into blank control
        group,positive control group(concanavalin A,5 μg/mL),different concentration of ginseng root extract groups(32,125,500
        μg/mL,by lyophilized powder). After 48 h of culture with the corresponding medicine,acridine orange staining method was used
        to detect autophagy of splenic lymphocyte;CCK-8 assay was used to detect the cell proliferation;ELISA assay was used to
        determine the levels of IL-4,IL-6 and TNF-α in cell culture;Western blotting method was used to detect the expression of LC3B
        and Beclin-1,as well as the phosphorylation of AMPK,AKT and mTOR. RESULTS:Compared with blank control group,32,
        125,500 μg/mL ginseng root extract could increase the number of acidic autophagosomes in splenic lymphocytes of mice(P<0.05
        or P<0.01);125,500 μg/mL Ginseng root extract could significantly enhance the survival rate of splenic lymphocytes,the levels
        of IL-4,IL-6 and TNF-α and the transformation of LC3BⅠ to LC3BⅡ,significantly increased the protein expression of Beclin-1,
