3.2小鼠炎症性肠病与hsCRPhsCRP是一种重要的急性期蛋白,它在正常人血清中含量甚少,但在炎性疾病的情况下,会迅速升高,在病变缓解后,恢复正常范围。hsCRP是预测心脑血管疾病的标志物,是致动脉粥样硬化的一个危险因子,是预测冠状动脉粥样硬化性心脏病的独立危险因子。而在炎症性肠病患者中,血清hsCRP水平较对照组明显升高(P<0.001),增加了动脉粥样硬化的风险,这为预防动脉粥样硬化提供了科学依据。

3.3小鼠炎症性肠病与吡格列酮PPARγ分为天然配体和人工合成配体,噻唑烷二酮类药物属于人工合成配体,它包括吡格列酮、曲格列酮、罗格列酮等,PPARγ的功能复杂多样,它除了具有降血糖的作用,还具有抗动脉粥样硬化、降血压、降血脂等作用。PPARγ经配体激活后,具有抑制炎症反应的作用,对机体的炎症反应进行负性调节[13,14]。本实验结果分析,吡格列酮组HE染色病理图片炎症反应明显轻于模型组,且相关血清炎症因子也明显减少(P<0.001)。这为治疗炎症性肠病提供了新的科学理论依据,也是治疗炎症性肠病的潜在靶点。

在炎症性肠病中血清hsCRP、TNFα水平明显升高,而给予吡格列酮干预后,血清hsCRP、TNFα水平明显降低,肠道HE染色病理图片提示吡格列酮组炎症明显减轻,提示PPARγ配体吡格列酮可能成为炎症性肠病治疗的潜在靶点。血清hsCRP水平在炎症性肠病中明显升高,提示动脉粥样硬化的发生率明显升高,PPARγ配体吡格列酮可降低血清hsCRP水平,从而降低了动脉粥样硬化发生的风险。
