1、中华中医药杂志(原中国医药学报)2014年6月第29卷第6期CJTCMP,June,2014,Vo1.29,No.6·研究报告·益肾化瘀方对单侧输尿管结扎大鼠肾组织中一SMA、E—cadherin表达的影响张琳琪,吕雁,刘红亮,赵永钦(河南中医学院第一附属医院,郑州450000;河南中医学院第三附属医院,郑州450008;河南省长垣县人民医院,长垣453400)摘要:目的:动态观察单侧输尿管结扎(UUO)大鼠肾组织中Or.一平滑肌肌动蛋白(Ot—SMA)、E一钙黏蛋白(E.eadherin)的表达及益肾化瘀方
2、对其影响。方法:将清洁级雄性SD大鼠108只随机分为假手术组,模型组,益肾化瘀方高、中、低剂量组及缬沙坦组,除假手术组外各组采用UUO模型,分别于术后第7、14、28天光镜下观察肾间质病理改变,免疫组化法观察大鼠肾组织仅一SMA、E—cadherin的表达变化。结果:造模后7d,大鼠’肾组织中d—SMA表达即明显增高,而E—cadherin表达逐渐减少;与模型组相比,各治疗组大鼠.SMA的表达减弱,E.cadherin的表达增强(P3、无统计学意义。结论:益肾化瘀方可能通过抑制大鼠肾组织中旺一SMA的早期高表达,上调E—cadherin的表达,而发挥抗肾间质纤维化作用。关键词:益肾化瘀方;单侧输尿管结扎;一平滑肌肌动蛋白;E一钙黏蛋白基金资助:河南省基础与前沿技术研究项目(NO.102300410124),河南省教育厅自然科学研究项目(No.2011A360o23)EffectofYishenHuayuRecipeOiltheexpressionof-SMAandE—cadherinonrenaltissuesOfUUOratsZHANGL4、in—qi,LYUYan,LIUHong—liang,ZHAOYong.qin(‘TheFirstAfiliatedHospitalofHenanUniversityofTCM,Zhengzhou450000,China;TheThirdAfiliatedHospitalofHenanUniversityofTCM,Zhengzhou450008,China;People’SHospitalofChangyuanCountyinHenan,Changyuan453400,China)Abstract:Obje5、ctive:ToobservetheeffectofYishenHuayuRecipeontheexpressionofa—SMAandE—cadherinonrenaltissuesofunilateralureteralobstruction(UUO)rats.Methods:108cleanSDmaleratswererandomlydividedintosham—operationgroup,mode1group,high,mediumandlowdoseofYishenHuayugroup,Vals6、artangroup.Exceptthesham—operationgroup,theothergroupswereusingtheUUOmode1.Qualitativepathologicalchangesofrenalinterstitialwereobservedunderlightmicroscopeonthepostoperativeday7,14and18.Immunohistochemistrymethodwasusedtoobservetheexpressionchangesof0t-SMA7、,E—cadherinonratrenaltissue.Results:Onthe7thdayafterestablishmentofUUOmodel,theexpressionofⅡ一SMAonrenaltissuesofratsincreasedsignificantly.whiletheexpressionofE—cadherinreducedgradually,Comparedwiththemodelgroup.theexpressionof—SMAinthetreatmentgroupsdecrea8、sedwhiletheexpressionofE—cadherinincreasedsignificant(P<0.01,P<0.05),especiallythechangesinthehighdoseofYishenHuayugroupandvalsartangroup,buttherewasnostatisticalsignificancebetweenthetwogroups.Conclus
