羽衣甘藍(lán)和西芹中膳食纖維與黃酮聯(lián)合使用對結(jié)腸炎的影響與潛在機(jī)制探究摘要：本研究旨在探究羽衣甘藍(lán)和西芹中膳食纖維與黃酮聯(lián)合使用對結(jié)腸炎的影響及其潛在機(jī)制。采用大鼠模型，通過口服膳食纖維和黃酮的組合劑量，觀察治療結(jié)腸炎的效果，同時(shí)在體內(nèi)和體外實(shí)驗(yàn)中檢測相應(yīng)的生物標(biāo)志物。結(jié)果表明，膳食纖維和黃酮聯(lián)合使用可顯著降低結(jié)腸炎發(fā)生率，改善大小腸移動性，降低炎性標(biāo)志物水平，并影響腸道菌群的構(gòu)成。這表明膳食纖維和黃酮聯(lián)合使用對結(jié)腸炎有潛在的保護(hù)作用。本研究為探究膳食纖維和黃酮聯(lián)合使用對結(jié)腸炎的治療作用提供了新的視角。

Introduction

結(jié)腸炎是一種消化系統(tǒng)疾病，其發(fā)病率逐年增加。膳食纖維和黃酮是兩種與結(jié)腸健康密切相關(guān)的營養(yǎng)素。其結(jié)腸保護(hù)作用與調(diào)節(jié)腸道菌群有關(guān)，但兩者的組合是否可以提高保護(hù)效果仍未被充分研究。

Methods

本研究選取SD大鼠，將它們分為4組：正常對照組（N組）、結(jié)腸炎組（C組）、膳食纖維組（F組）和膳食纖維與黃酮組（F+H組）。除了N組，其他三組大鼠均注射一種誘導(dǎo)結(jié)腸炎的化合物DSS。F組和F+H組分別口服相應(yīng)的組合劑量，C組和N組口服等容量的生理鹽水。治療階段結(jié)束后，觀察體重、大小腸移動性和腸道菌群等指標(biāo)，在體內(nèi)和體外實(shí)驗(yàn)中檢測相應(yīng)的生物標(biāo)志物，分析每個(gè)組的差異。

Results

與C組相比，F(xiàn)+H組表現(xiàn)出更好的治療效果（P<0.05），降低了結(jié)腸炎發(fā)生率，形成更平穩(wěn)的腸道運(yùn)動模式，以及更低的腸道炎癥標(biāo)志物IL-1β和IL-6水平（P<0.05）。另外，F(xiàn)+H組改善了結(jié)腸菌群組成，發(fā)現(xiàn)其中一些共生菌種含量直接與C組的結(jié)腸炎狀態(tài)相關(guān)。

Conclusion

本研究發(fā)現(xiàn)，西芹和羽衣甘藍(lán)中的膳食纖維和黃酮聯(lián)合使用可顯著降低結(jié)腸炎發(fā)生率、改善大小腸移動性，以及降低炎性標(biāo)志物水平，并影響腸道菌群的構(gòu)成。這表明膳食纖維和黃酮聯(lián)合使用對結(jié)腸炎有潛在的保護(hù)作用。Introduction
