摘要:
目的   观察匹维溴胺对腹泻型肠易激综合征(D-IBS)模型大鼠血清以及结肠组织血管活性肠肽(vasoactive intestinal peptide,VIP)含量、结肠组织水通道蛋白3(aquaporin 3, AQP3)表达的影响,探讨其治疗D-IBS的作用机制。   方法   采用慢性应激与束缚相结合方法建立D-IBS大鼠模型。采用ELISA法检测VIP含量;采用Real time-PCR法和SABC免疫组化法检测AQP3的表达。   结果   在血清和结肠组织中VIP的含量,与对照组[(3.092±0.613)ng/ml,(3.811±0.275)ng/ml]比较,模型组[(10.460±1.666)ng/ml,(4.495±0.341) ng/ml]与匹维溴胺组[(5.639±1.163)ng/ml,(4.063±0.534)ng/ml]均升高(P<0.05),尤以模型组升高的更为明显(P<0.01);两组AQP3的表达均下调(P<0.01),尤以模型组AQP3蛋白表达下调显著。   结论   匹维溴胺治疗D-IBS的作用机制之一,可能与抑制结肠组织中VIP分泌和上调AQP3表达有关。
Abstract:
Objective   To study the serum vasoactive intestinal peptide (VIP) level and the effect of pinaverium bromide (PB) on expression of aquaporin 3 (AQP3) in colon tissue and diarrhea-predominant irritable bowel syndrome (D-IBS) model of rats.    Methods   A D-IBS rat model was established with chronic stress plus binding limbs. Level of VIP was measured by ELISA and expression of AQP3 was detected by real-time PCR and SABC, respectively.    Results   The VIP level in serum and colon tissue was higher in model group (10.46±1.666  and 4.495±0.341 ng/ml) and PB group (5.639±1.163 and 4.063±0.534 ng/ml) than in control group (3.092±0.613 and 3.811±0.275 ng/ml) (P<0. 05), which was particularly high in model group. The expression of AQP3 in colon tissue was remarkably decreased in model group and PB group, especially in model group (P<0. 01).    Conclusion   PB improves D-IBS by inhibiting the secretion of VIP and up-regulating the AQP3 expression in colon tissue.
