摘要:

文题释义:
系统性红斑狼疮:是一种原因不明的自身免疫疾病,血清中出现自身抗体和免疫复合物,同时有严重肾小球肾炎。研究证实T细胞免疫异常与系统性红斑狼疮的发生发展和预后有较大关系。辅助性T细胞17型是近年来发现的一种新型CD4+效应性T细胞,可分泌白细胞介素17,参与到固有免疫及适应性免疫应答中,在系统性红斑狼疮发病中起重要作用。
树鼩:是非人灵长类替代动物,具有资源丰富、成本较低、与人类亲缘关系较近等优势,近年来人类疾病的树鼩模型受到越来越多的关注。

背景:系统性红斑狼疮是一种原因不明的自身免疫疾病,建立系统性红斑狼疮树鼩模型,有利于弄清其发病机制,并为干细胞移植治疗自身免疫疾病提供依据。
目的:建立系统性红斑狼疮树鼩模型以及脐带间充质干细胞移植的治疗效果评估。
方法:树鼩分组腹腔注射降植烷、脂多糖和联合注射,注射后3周筛选成模树鼩12只分为治疗组和模型对照组各6只,另选6只为正常对照组。治疗组每只树鼩尾静脉回输1×106个DiR标记的树鼩脐带间充质干细胞,回输后2周取树鼩的心、肝、脾、肺、肾做病理切片进行苏木精-伊红染色,肾组织进行masson染色和免疫复合物检测,同时取3组树鼩的心、肝、脾、肺、肾进行体外成像。
结果与结论:①苏木精-伊红染色表明模型对照组心、肝、脾、肺、肾有不同程度的病理改变,肾组织有大量免疫复合物沉积,治疗组病理改变好转,结构恢复到接近正常对照组;②体外成像表明DiR标记细胞主要分布于治疗组树鼩的肺、肝和脾,治疗组树鼩的荧光强度值明显大于正常对照组和模型对照组,差异有显著性意义(P < 0.05);③结果表明,腹腔联合注射降植烷和脂多糖是诱导树鼩发生系统性红斑狼疮病理改变的最佳方法,用脐带间充质干细胞治疗后病理改变发生好转,说明脐带间充质干细胞对树鼩系统性红斑狼疮模型有一定的治疗效果。

Abstract: BACKGROUND: Systemic lupus erythematosus is an autoimmune disease with unknown causes. To establish a tree shrew model of systemic lupus erythematosus is helpful to understand its pathogenesis and provide evidence for stem cell transplantation in the treatment of autoimmune diseases.  
OBJECTIVE: To establish a tree shrew model of systemic lupus erythematosus and to assess the therapeutic effect of umbilical cord mesenchymal stem cell transplantation.  
METHODS:  Tree shrews were grouped and intraperitoneally injected pristane, lipopolysaccharide, and their combination. At 3 weeks after injection, 12 tree shrew models were divided into treatment group and model control group (n=6 per group). An additional 6 models were selected as a normal control group. In the treatment group, each tree shrew was injected with 1×106 DiR-labeled umbilical cord mesenchymal stem cells through caudal vein. Two weeks later, the heart, liver, spleen, lung and kidney of tree shrews were taken for pathological sections. The sections received hematoxylin-eosin staining, kidney Masson staining and immune complex detection. Simultaneously, the heart, liver, spleen, lung and kidney of the three groups of tree shrews were taken for in vitro imaging.   
RESULTS AND CONCLUSION: (1) Hematoxylin-eosin staining showed pathological changes of the heart, liver, spleen, lung and kidney in the model control group; and there were a lot of immune complex deposits in renal tissue in the model control group. The pathological changes in the treatment group improved, and the structure recovered to close to the normal control group. (2) In vitro imaging showed that DiR-labeled cells were mainly distributed in the lung, liver and spleen of the tree shrews in the treatment group. The fluorescence intensity of tree shrews in the treatment group was significantly higher than that in the normal control group and model control group (P < 0.05). (3) Results demonstrated that intraperitoneal injection of pristane and lipopolysaccharide is the best method to induce pathological changes of systemic lupus erythematosus in tree shrews. The pathological changes after treatment with umbilical cord mesenchymal stem cells have improved, indicating that umbilical cord mesenchymal stem cells have certain treatment effects on tree shrew models of systemic lupus erythematosus.
