Resümee

Ziel ist es, die Rolle des Toll-like-Rezeptor 4 (TLR4) / Myeloid-Differenzierungsfaktor 88 (MyD88) / Kerntranskriptionsfaktor-κB (NF-κB) Signalwegs bei der Schädigung der Darm-Schleimhautbarriere bei Colitis ulcerosa und den Interventionsmechanismus der Shaoyao-Decoction zu untersuchen. Methoden: 60 SD-Ratten wurden in Kontrollgruppe, Modellgruppe, Mesalazin-Gruppe (0,42 g·kg⁻¹) sowie niedrige, mittlere und hohe Dosisgruppen der Shaoyao-Decoction (11,1, 22,2, 44,4 g·kg⁻¹) eingeteilt. Das Colitis-ulcerosa-Modell wurde mittels 2,4,6-Trinitrobenzolsulfonsäure (TNBS) induziert. Nach erfolgreicher Modellierung erhielten die Gruppen physiologische Kochsalzlösung, Mesalazin bzw. Shaoyao-Decoction oral für 7 Tage. Die Länge und Masse des Kolons wurden beobachtet, histopathologische Veränderungen des Kolongewebes mit Hämatoxylin-Eosin (HE) Färbung untersucht, die Expression inflammatorischer Faktoren IL-8, COX-2, JAM-1 und Claudin-1 im Kolongewebe immunhistochemisch bestimmt sowie die Expression der Proteine TLR4, MyD88 und NF-κB mittels Western Blot analysiert. Ergebnisse: Im Vergleich zur Normalgruppe war der Krankheitsaktivitätsindex (DAI) in der Modellgruppe signifikant erhöht (P<0,01), die Kolonlänge und -masse signifikant verringert (P<0,01), die Proteinexpression von JAM-1 und Claudin-1 signifikant vermindert (P<0,01), während die Proteinexpression von IL-8, COX-2, TLR4, MyD88 und NF-κB p65 signifikant erhöht war (P<0,01). Im Vergleich zur Modellgruppe zeigten die behandelten Gruppen eine signifikante Senkung des DAI (P<0,05, P<0,01), eine signifikante Zunahme der Kolonlänge und -masse (P<0,05, P<0,01), eine signifikante Erhöhung der Proteinexpression von JAM-1 und Claudin-1 (P<0,01) sowie eine signifikante Verringerung der Proteinspiegel von IL-8, COX-2, TLR4, MyD88 und NF-κB p65 (P<0,01). Fazit: Die Shaoyao-Decoction kann die Darmentzündung verringern, die Schleimhautschädigung verbessern und die Integrität der Darmbarriere schützen, was wahrscheinlich mit der Regulation des TLR4/MyD88/NF-κB Signalwegs zusammenhängt.
