摘要 目的观察野百合碱诱导的肺动脉高压大鼠右心室CD36、过氧化物酶体增殖剂激活受体α(PPARα)、过氧化物酶体增殖剂激活受体γ(PPARγ)的表达情况,探讨肺动脉高压大鼠右心室脂肪酸代谢紊乱的机制。方法24只大鼠随机分成对照组10只和观察组14只。观察组通过一次性腹腔注射60 mg/kg野百合碱来建立肺动脉高压模型,对照组腹腔注射相同剂量的生理盐水。4周时通过右心导管法测定大鼠的平均右心室压(mRVP)以及右心室收缩压(RVSP);称量右心室(RV)、左心室+室间隔(LV+S)的质量,计算右心肥厚指数[RV/(LV+S)];采用实时荧光定量PCR方法检测右心室CD36、PPARα、PPARγ的mRNA表达的变化。结果 4周时,观察组mRVP和RVSP高于对照组(P均<0.05),肺动脉高压模型建立成功。对照组右心室心肌肥厚指数、心肌细胞横截面积分别为0.20±0.02、(290.32±28.16)μm2,观察组分别为0.40±0.07、(187.92±21.15)μm2,两组比较差异有统计学意义(P均<0.05)。对照组右心室CD36、PPARα、PPARγmRNA相对表达量分别为1.00±0.00、1.00±0.00、1.00±0.00,观察组分别为1.26±0.08、0.71±0.06、0.48±0.09,观察组右心室CD36表达量高于对照组,PPARα、PPARγ的表达量低于对照组(P均<0.05)。结论野百合碱诱导的肺动脉高压大鼠右心室CD36的表达增加和PPARα、PPARγ表达减少,导致右心室脂肪酸利用水平降低,形成脂毒性,引起右心室功能紊乱。
