文题释义:
五味子:木兰科植物五味子或华中五味子的干燥成熟果实,五味子可改善肝功能、减轻肝细胞脂质,防止肝纤维化的作用,可用于慢性肝炎、迁延性肝炎等。近年研究认为五味子也可用于肝移植患者。
调节性T细胞:是一类控制体内自身免疫反应性的T细胞亚群。调节性T细胞可分为天然产生的自然调节性T细胞和诱导产生的适应性调节性T细胞,如Th3、Tr1,另外尚有CD8 Treg、NKT细胞等,与自身免疫性疾病的发生关系密切,其异常表达可导致自身免疫性疾病。调节性T细胞对于自身免疫性疾病的发生和发展都具有重要意义,对其进行深入研究将有助于了解自身免疫性疾病的发病机制,对疾病预后判断、进一步的治疗有着深远的意义。
摘要
背景:
五味子提取物的功效有很多,但五味子提取物在肝移植后的免疫改变方面所起的作用研究甚少。
目的:探讨五味子提取物对肝移植模型犬的Th17细胞和Treg细胞失衡的影响。
方法:建立肝移植犬模型,随后随机分成对照组10只和五味子组10只,肝移植后对照组给予葡萄糖,五味子组给予五味子水提取物。检测肝移植后1,3,6和9 d的存活率、肝功能、外周血Th17细胞和Treg细胞、外周血白细胞介素17、23、10和转化生长因子β1水平;比较2组犬的肝病理变化。
结果与结论:①与对照组比,五味子组肝移植模型犬的生存期明显延长(P < 0.05);②肝移植后3, 6和9 d五味子组谷丙转氨酶、谷草转氨酶及总胆红素水平显著低于对照组(P < 0.05);③肝移植后3,6及9 d,对照组的Treg显著降低,Th17显著增高(P < 0.05),与对照组比,五味子组的Th17增高不明显,Treg无显著变化,但有增高趋势;④肝移植后3,6及9 d,与对照组相比,五味子组白细胞介素17和白细胞介素 23水平显著降低,白细胞介素10和转化生长因子β1水平显著升高(P < 0.05);⑤与对照组比较,五味子组可降低炎症因子浸润,改善肝的病变程度;⑥结果提示,五味子提取物可明显改善肝移植模型犬的生存状况,肝功能和供体肝存活,可能与改善Th17细胞和Treg细胞失衡有关。

Abstract:

BACKGROUND: Schisandra extract has various effects, but little is known about the role of Schisandrins extract in immune changes after liver transplantation.
OBJECTIVE: To investigate the effect of Schisandra extract on Th17/regulatory T cells (Treg) imbalance in dogs undergoing liver transplantation.
METHODS: The model dogs undergoing liver transplantation were established, and then divided into control and Schisandra groups (n=10 per group). The control group received glucose and the Schisandra group was given Schisandra extracts postoperatively. The survival rate, liver function, Th17 and Treg cells in peripheral blood, as well as levels of interleukin 17, interleukin 23, interleukin 10 and tumor growth factor β1 in peripheral blood were determined at 1, 3, 6 and 9 days after liver transplantation. The pathological changes of canine liver were compared between groups.
RESULTS AND CONCLUSION: Compared with control group, the survival rate was significantly increased in the Schisandra group (P < 0.05). Compared with the control group, the levels of alanine aminotransferase, aspartate aminotransferase and total bilirubin in the Schisandra group were significantly lower than those in the control group at 3, 6 and 9 days after liver transplantation (P < 0.05). In the control group, the Treg cells were significantly decreased, and Th17 cells were significantly increased (P < 0.05). Compared with the control group, the Th17 and Treg cells in the Schisandra group showed no significant change, but tended to be increased. Compared with the control group, in the Schisandra group, the levels of interleukin 17 and interleukin 23 were significantly decreased, and levels of interleukin 10 and tumor growth factor β1 were significantly increased (P < 0.05). The inflammatory factor infiltration and liver pathology were reduced in the Schisandra group compared with the control group. Our findings imply that Schisandra extracts can significantly improve living conditions, liver function and donor liver’s activity in dogs undergoing liver transplantation, probably by improving the Th17/Treg cell imbalance.
