摘要：目的:观察以温补脾肾法为指导的理中汤合四神丸对脾肾阳虚型溃疡性结肠炎(UC)大鼠模型病变结肠组织中JAK2、STAT3、p-STAT3、SOCS6蛋白及基因表达的影响。方法:采用病证结合造模方法复制脾肾阳虚型UC模型,成模大鼠随机分为模型组、柳氮磺砒啶组(SASP组)、理中汤合四神丸高、中、低剂量组,16只/组,同时设16只大鼠作为空白组。空白组与模型组给予蒸馏水灌胃,各治疗组给予对应的药物及剂量灌胃治疗,连续21 d。HE染色观察大鼠结肠黏膜组织病理变化;免疫组化法检测大鼠结肠黏膜组织中JAK2、STAT3、p-STAT3、SOCS6蛋白表达情况;RT-qPCR检测大鼠JAK2、STAT3、SOCS6mRNA表达情况;ELISA检测大鼠组织和血清中TGF-β1、ICAM-1含量。结果:与空白组相比,模型组大鼠结肠黏膜组织JAK2、STAT3、p-STAT3蛋白表达显著升高(P<0.01),JAK2、STAT3、p-STAT3蛋白着色深,表达呈强阳性,SOCS6蛋白表达显著降低(P<0.01),SOCS6蛋白着色浅,表达呈弱阳性。JAK2、STAT3 mRNA表达显著升高,SOCS6 mRNA表达显著降低(P<0.01),组织和血清中TGF-β1含量显著降低(P<0.01),ICAM-1含量显著升高(P<0.01);与模型组相比,中药高、中剂量组及SASP组JAK2、STAT3、p-STAT3蛋白表达显著降低(P<0.01),JAK2、STAT3、p-STAT3蛋白着色浅,表达呈弱阳性,SOCS6蛋白表达显著升高(P<0.01),SOCS6蛋白着色深,表达呈强阳性。JAK2、STAT3 mRNA表达显著降低(P<0.01),SOCS6 mRNA表达显著升高(P<0.01),组织和血清中TGF-β1含量显著升高(P<0.01),ICAM-1含量显著降低(P<0.01)。结论:以温补脾肾法为指导的理中汤合四神丸可能通过抑制JAK2/STAT3-SOCS6信号通路的激活,调节免疫系统平衡,修复受损结肠黏膜,达到治疗UC的目的。
Objective:To observe the effects of Lizhong Decoction combined with Sishen Pills guided by the method of warming and tonifying the spleen and kidney on expressions of JAK2,STAT3,p-STAT3 and SOCS6 proteins and genes in diseased colon of rats with ulcerative colitis(UC)of spleen and kidney yang deficiency type.Methods:Models of spleen kidney yang UC were established by combining disease and syndrome.Rats were randomly divided into model group,sulfasalazine group(SASP group),Decoction combined with Sishen Pills high,medium and low doses groups,with 16 rats in each group,at the same time,16 rats were set up as blank group.Blank group and model group were given distilled water by gavage,and each treatment group was given corresponding drugs and doses by gavage for 21 days.Histopathological changes of colonic mucosa were observed by HE staining;expressions of JAK2,STAT3,p-STAT3 and SOCS6 proteins in rat colonic mucosa were detected by immunohistochemistry;RT-qPCR was used to detect expressions of JAK2,STAT3 and SOCS6 mRNA in rats;TGF-β1,ICAM-1 contents in tissues and serum of rats were detected by ELISA.Results:Compared with blank group,expressions of JAK2,STAT3 and p-STAT3 protein in colonic mucosa of model group were increased significantly(P<0.01),JAK2,STAT3 and p-STAT3 protein were deeply stained and strongly positive,while expression of SOCS6 protein was decreased significantly(P<0.01),SOCS6 protein was lightly stained and its expression was weakly positive.Expressions of JAK2 and STAT3 mRNA were increased significantly,while expression of SOCS6 mRNA was decreased significantly(P<0.01),and TGF-β1 in tissue and serum was decreased significantly(P<0.01),while content of ICAM-1 was increased significantly(P<0.01);compared with model group,expressions of JAK2,STAT3 and p-STAT3 protein of drug treatment groups were decreased significantly(P<0.01),JAK2,STAT3 and p-STAT3 protein were lightly stained,and their expressions were weakly positive,while expression of SOCS6 protein was increased significantly(P<0.01),SOCS6 protein was deeply stained and its expression was strongly positive.Expressions of JAK2 and STAT3 mRNA were decreased significantly(P<0.01),while expression of SOCS6 mRNA was increased significantly(P<0.01),and TGF-β1 in tissue and serum was increased significantly(P<0.01),content of ICAM-1 was decreased significantly(P<0.01).Conclusion:Decoction combined with Sishen Pills guided by the method of warming and tonifying the spleen and kidney may regulate the balance of immune system,and repair damaged colonic mucosa by inhibiting the activation of JAK2/STAT3-SOCS6 signal pathway,so as to achieve the purpose of treating UC.
