目的探究建立痛风性关节炎湿热蕴结证大鼠模型的方法。方法选用健康成年SD雄性大鼠40只,按随机法将大鼠分为4组:正常对照组(A组),痛风组(B组),湿热组(C组),痛风加湿热模型组(D组),每组10只。各组经不同的处理或造模后,观察大鼠的一般状态,用Bradford法检测大鼠尿液水通道蛋白2(AQP2),放射免疫法检测内皮素(ET)、降钙素基因相关肽(CGRP),ELISA法定量测定热休克蛋白70(HSP70),HE染色、光镜下观察大鼠踝关节滑膜组织、舌组织。结果一般状态,C、D组符合湿热证的表现,B、D组符合痛风性关节炎的表现。尿液AQP2:A、B组高于C组和D组(P<0.05)。血浆ET:A组低于B、C、D组(P<0.05),B组低于C、D组(P<0.05),C组低于D组(P<0.05)。血浆CGRP:A组高于B、C、D组(P<0.05),B组低于C组和D组(P<0.05),C组低于D组(P<0.05)。血清HSP70:B、D组高于A、C组(P<0.05)。结论在高脂高糖饮食+湿热环境+关节腔注射药物的复合干预下,可以成功复制痛风性关节炎湿热蕴结证的大鼠动物模型。

〔Abstract〕Objective To explore the methods for building the gouty arthritis rat models with damp-heat syndrome. Methods 40 healthy adult SD male rats were divided into 4 groups:normal control group(group A),gout group(group B),damp-heat group(group C),gout with damp-heat group(group D),10 in each group.The general status of the rats was observed before and after establishment.The water rat urine protein channel 2(AQP2)was detected by Bradford method;the endothelin(ET)and calcitonin gene-related peptide(CGRP)were measured by radiation immune method.HSP70 was detected byELISAmethod.TheratsweredyedbyHE.Synovialandtonguetissuesofanklesinratswereobservedby light-microscopy.Results In the general status,group C and D showed the manifestations in hot and humid,group B and D were in accordance with the performance of gouty arthritis.Urine AQP2 in group A and B was higher than that in group C and D(P<0.05).The content of plasma ET in group A was lower than that in group B,C and D(P<0.05),group B was lower than Group C and D,and group C was lower than group D(P<0.05).Plasma CGRP in group A was higher than that in group B,C and D(P<0.05),group B is lower than group C and group D(P<0.05),group C is lower than group D(P<0.05).Serum HSP70 in group B and D were higher than group A and C(P<0.05).Conclusion Under the comprehensive intervention of the high fat and sugar diet+damp-heat environment+articular cavity drug injection,the gouty arthritis rat models with damp-heat syndrome can be built successfully.

痛风(Gout)是体内嘌呤代谢紊乱导致的代谢性疾病,病因是尿酸盐在关节及关节周围组织中沉积,引起的急性炎症反应[1]。在现今实验研究中,单纯痛风性关节炎模型及单纯中医湿热证大鼠模型的研究较多,但痛风性关节炎“病”与中医湿热证“证”病证结合动物模型的研究较少,该病证结合动物模型的建立,成为亟待解决的问题。……
