摘要:

目的 分析MAPK通过调控TLR4/MyD88/NF-κB通路对妊娠期肠梗阻胃肠功能的影响。 方法 选取105只SPF级Wistar大鼠,雌性、雄性分别为70、35只,将所有大鼠同笼放置后,共有33只雌性大鼠妊娠成功,将妊娠成功的8只作为空白组,剩余25只雌性大鼠建立肠梗阻模型,最终建模成功24只,将其分为模型组、上调组、下调组各8只。 结果 与模型组相比,上调组MAPK表达量、VIP、GAS、TNF-α、IL-6水平、TLR4、Myd88、NF-κB mRNA表达量及相对表达量上升,MOT、IL-4、IL-10水平下降,下调组MAPK表达量、VIP、GAS、TNF-α、IL-6水平、TLR4、Myd88、NF-κB mRNA表达量及相对表达量下降,MOT、IL-4、IL-10水平上升(P < 0.05)。 结论 妊娠期肠梗阻大鼠经下调MAPK干预后胃肠功能改善,炎性反应减轻,其机制可能与TLR4/Myd88/NF-κB通路得到抑制有关。

Abstract:

Objective To investigate the effect of MAPK on intestinal obstruction during pregnancy. Methods A total of 105 SPF Wistar rats (female = 70 and male = 35) were selected. After placing all the rats in the same cage, 33 female rats were pregnant, and 8 rats were assigned to the control group and the other 25 rats were used to established bowel obstruction model. A total of 24 rats were successfully modelled, which were divided into model group(n = 8), up-regulation group(n = 8), and down-regulation group(n = 8). Results Compared with the model group, MAPK expression, VIP, GAS, TNF-α, IL-6 levels, TLR4, Myd88, NF-κBmRNA were increased and MOT, IL-4, IL-10 levels were decreased in up-regulation group; MAPK expression, VIP, GAS, TNF-α, IL-6 levels, TLR4, Myd88, NF-κB mRNA were decreased and MOT, IL-4, IL-10 levels were increased in down-regulation group (P < 0.05). Conclusion MAPK down-regulation reduced inflammatory response and improved bowel obstruction in pregnancy, and the mechanism may be related to the inhibition of TLR4/Myd88/NF-κB pathway.
