中文摘要:

目的:研究细胞核因子-κB受体活化因子配基(receptoractivatorofnuclearfactor-κBligand,RANKL)在佐剂性关节炎大鼠发病中的作用,探讨亚砷酸对RANKL的影响及其对佐剂性关节炎大鼠的治疗作用。

方法:40只大鼠随机分成4组:正常对照组、模型组、低剂量亚砷酸组(LSA,1.5mg.kg-1.d-1)、高剂量亚砷酸组(HSA,3.0mg.kg-1.d-1),正常对照组与模型组给予生理盐水2ml/d。免疫组化、原位杂交方法检测各组RANKL蛋白及其mRNA的表达;HE染色观察各组滑膜组织形态变化。

结果:与正常对照组比较,模型组RANKL蛋白及其mRNA大量表达(P<0.01);与模型组比较,LSA组及HSA组RANKL蛋白及其mRNA表达降低(P<0.01),且HSA组更明显。

结论:RANKL在大鼠佐剂性关节炎发生发展中具有重要作用;亚砷酸能下调RANKL蛋白及其mRNA的表达,提示亚砷酸对RA有一定的治疗作用。

Expression of recept activator of nuclear factor-κB ligand (RANKL) of synovium in adjuvant arthritis rats and effects of sodium arsenite on them
ABSTRACT  

Objective:To study the expression of receptor activator of nuclear factor-κB ligand(RANKL)in synovium of adjuvant arthritis rats and effects of sodium arsenite(SA)on RANKL.

Methods:Forty Wistar female rats were randomly divided into 4 groups:normal control group,model group,low concentration sodium arsenite group(LSA)and high concentration sodium arsenite group(HSA).LSA group and HAS group were treated with SA(1.5 mg.kg-1.d-1 and 3 mg kg-1.d-1)through abdominal injection,the normal control group and the model group were treated with saline(1 ml/d).The expressions of RANKL protein and mRNA of synovium by immunohistochemistry and by in situ hybridization.Light microscope was used to observe the synovium by HE.

Results:Compared with normal control group,the expressions of RANKL protein and mRNA in the synovium were up-regulated in the model group(P<0.01)and were inhibited by sodium arsenite(P<0.01),especially in the HAS group.

Conclusion:RANKL may play an important role in the development adjuvant arthritis.Sodium arsenite can down-regulate the expressions of RANKL protein and mRNA and may have some therapeutic effects in rheumatoid arthritis.
