摘要: 目的:探讨滋阴补肾方联合糖皮质激素对系统性红斑狼疮(SLE)小鼠T淋巴细胞亚群和炎症细胞因子的影响,阐明中、西药联合对SLE的作用机制。方法:将50只MRL/lpr小鼠随机分为模型组,西药组,中药组,低和高剂量联合组(n=10);另选10只C57BL/6小鼠作为对照组。对照组和模型组小鼠灌胃给予0.5mL·d-1生理盐水,西药组小鼠灌胃给予12.5mg·kg-1醋酸泼尼松(糖皮质激素),中药组小鼠灌胃给予25.0g·kg-1滋阴补肾方,低和高剂量联合组小鼠分别灌胃给予12.5和25.0g·kg-1滋阴补肾方和6.25 mg·kg-1醋酸泼尼松。连续给药21d后,计算各组小鼠脾脏指数和胸腺指数。采用流式细胞术检测各组小鼠外周血中CD3+、CD4+和CD8+T淋巴细胞亚群水平。采用酶联免疫吸附试验(ELISA)法检测小鼠血清白细胞介素4(IL-4)、白细胞介素6(IL-6)和γ-干扰素(IFN-γ)水平。结果:与模型组比较,西药组和低及高剂量联合组小鼠脾脏指数和胸腺指数明显降低(P<0.05);与模型组比较,中药组,低和高剂量联合组CD3+和CD4+ T淋巴细胞水平明显升高(P<0.05);与模型组比较,西药组、中药组和低及高剂量联合组CD8+T淋巴细胞水平明显降低(P<0.05),血清中IL-4和IL-6水平明显降低(P<0.05),IFN-γ水平明显升高(P<0.05),且系膜细胞与系膜基质增生明显改善,肾间质炎性细胞浸润减轻;与低剂量联合组比较,高剂量联合组小鼠CD4+T淋巴细胞水平、CD4+/CD8+比值和IFN-γ水平明显升高(P<0.05),CD8+T淋巴细胞水平明显降低(P<0.05),其他指标比较差异均无统计学意义(P>0.05)。结论:滋阴补肾方联合糖皮质激素可降低SLE小鼠炎性细胞因子水平,调节T淋巴细胞亚群平衡,弥补单用糖皮质激素免疫抑制治疗后不能扶正机体内环境的不足,有效调节机体免疫平衡。

Abstract: Objective: To investigate the effects of Nourishing Kidney-Yin Prescription combined with glucocorticoid on the T lymphocyte subsets and inflammatory cytokines in the mice with systemic lupus erythematosus(SLE), and to elucidate the mechanism of Chinese and Western medicine combination in the treatment of SLE.Methods: Fifty MRL/ lpr mice were randomly divided into model group, Western medicine group, Chinese medicine group, low dose and high dose of combintion groups(n=10). Ten C57BL/6 mice were selected as control group.The mice in control group and model group were given 0.5 mL·d-1 normal saline by gavage;the mice in Western medicine group were given 12.5 mg·kg-1 prednisone acetate (glucocorticoid) by gavage;the mice in Chinese medicine group were given 25.0 g·kg-1 Nourishing Kindey-Yin Prescription by gavage;the mice in low and high doses of combination groups were given 12.5 and 25.0 g·kg-1 Nourishing Kidney-Yin prescription by gavage and 6.25 mg·kg-1 prednisone acetate, respectively. After 21 d of continuous administration,the spleen indexes and thymus indexes of the mice in various groups were calculated. The levels of CD3+, CD4+ and CD8+T lymphocyte subsets in the periphreal blood of the mice in various groups were determined by flow cytometry.The serum levels of interleukin-4 (IL-4), interleukin-6 (IL-6) and γ- interferon (IFN-γ) were measured by enzyme-linked immunosorbent assay(ELISA) method.Results: Compared with model group, the spleen indexes and thymus indexes of the mice in Western medicine, low dose of combination group and high dose of combination group were decreased obviously (P<0.05).Compared with model group,the levels of CD3+ lymphocytes and CD4 +T lymphocytes in Chinese medicine group,low dose of combintion group and high dose of combination group were significantly increased (P<0.05).Compared with model group,the CD8 +T lymphocyte levels in Western medicine group,Chinese medicine group,low dose combination group and high dose combination group were significantly decreased (P<0.05), the serum IL-4 and IL-6 levels were obviously decreased (P<0.05), and the IFN-γ levels were significantly increased(P<0.05);the mesagial cell and mesangial matrix hyperplasia were improved,and the renal intestitial inflammatory cell infiltration was relieved.Conclusion: Nourishing Kidney-Yin Prescription combined with glucocorticoid can effectively regulate the body's immune balance by reducing the inflammatory cytokines, regulating T lymphocyte subgroup equilibrium, and recovering the deficiency of the immune-suppression therapy by monosaccharide corticosteroids.
