目的通过建立2型糖尿病大鼠模型诱导心肌纤维化的发生,探究血管紧张素Ⅱ1型受体相关蛋白的内源性配体亚型之一Apelin-13对糖尿病大鼠心肌纤维化防治作用的可能机制。方法高脂高糖喂养联合尾静脉注射小剂量链脲佐菌素构建2型糖尿病大鼠模型。48只Wistar大鼠随机分为四组:正常对照组、模型组、Apelin-13组、阻断剂组(SB431542组)。各组大鼠给予相应干预措施12周,取材后行Masson染色,光镜下观察心肌细胞形态学改变及间质胶原纤维沉积情况,测算胶原容积分数(CVF),ELISA检测心肌组织内Ⅰ型、Ⅲ型胶原纤维含量,免疫组织化学染色分析心肌内信号蛋白转化生长因子β1(TGF-β1)和转化生长因子β1Ⅰ型受体(TβRⅠ)的表达水平,Western blot检测下游信号蛋白smad2、p-smad2、smad3、p-smad3的表达水平。结果与正常对照组相比,模型组大鼠心肌组织CVF值、Ⅰ型和Ⅲ型胶原纤维含量明显升高,伴随信号通路蛋白TGF-β1、TβRⅠ、smad2、p-smad2、smad3、p-smad3表达增强(Plin-13或SB431542干预的糖尿病大鼠心肌组织CVF值、Ⅰ型和Ⅲ型胶原纤维含量则明显下降(Plin-13组各通路蛋白的表达均显著下调(P0.05),其余信号蛋白的表达亦明显减弱(Plin-13可抑制糖尿病大鼠心肌纤维化的发生,此作用是通过减弱TGF-β1/TβR/smads信号转导通路的过度激活得以实现的。

目的观察前列地尔即前列腺素E1(PGE1)对糖尿病大鼠心功能的影响,探讨其对心功能的保护作用及相关机制。方法 50只SD大鼠随机选取10只作为对照组,给予普通饲料喂养;其余40只高糖高脂饲料喂养4周后一次性腹腔注射0.1%链脲佐菌素建立糖尿病模型,造模成功后随机分为模型组、PGE1低剂量组、PGE1中剂量组和PGE1高剂量组。PGE1低、中、高剂量组分别给予前列地尔注射液0.5、1.0、2.0μg/kg每天1次腹腔注射,对照组及模型组给予相应体积的生理盐水腹腔注射。连续给药8周后进行各项指标检测:血清转化生长因子β1(TGF-β1)、血浆N末端B型脑钠肽原(NT-pro BNP)、糖化血红蛋白(Hb A1c);Masson三色染色检测心肌组织胶原容积分数(CVF);Western blot检测心肌组织信号通路相关蛋白TGF-β1、Smad3、Smad7的表达情况。结果与对照组相比,模型组大鼠血清TGF-β1、血浆NT-pro BNP、Hb A1c浓度及CVF值明显升高,心肌组织内TGF-β1、Smad3蛋白含量显著上升,Smad7表达量明显下降(均P<0.01)。与模型组比较,PGE1中、高剂量组血清TGF-β1、血浆NTpro BNP浓度及心肌CVF明显下调,心肌TGF-β1、Smad3蛋白表达水平亦明显下调,Smad7的表达量则回升(均P<0.01);PGE1高剂量组上述改变更明显。PGE1低剂量组与模型组比较各指标差异无统计学意义。结论前列地尔具有抑制糖尿病大鼠心肌纤维化、改善心功能的作用,其机制与调节TGF-β1/Smad信号转导通路有关。
