The contents of inflammatory mediators and the expression of apoptosis genes in uterine muscle as well as the contents of immune cells in peripheral blood were determined 21 d after molding and intervention.Results:TLR4, NF-κB, TNF-α, ICAM-1 and IL-8 levels as well as Fas, TNFR-1, GRP78, CHOP and Caspase-3 mRNA expression in uterine muscle tissue and CD3+CD8+T cell in peripheral blood of pelvic inflammation group were higher than those of control group whereas peripheral blood CD3+CD4+T cell, red blood cell C3b receptor rosette rate and erythrocyte immune complex rosette were lower than those of control group;TLR4, NF-κB, TNF-α, ICAM-1 and IL-8 levels as well as Fas, TNFR-1, GRP78, CHOP and Caspase-3 mRNA expression in uterine muscle tissue as well as CD3+CD8+T cell in peripheral blood of smilax bockii warb group were lower than those of pelvic inflammation group whereas peripheral blood CD3+CD4+T cell, red blood cell C3b receptor rosette rate and erythrocyte immune complex rosette were higher than those of pelvic inflammation group. Conclusion:Smilax bockii warb polysaccharide for chronic pelvic inflammatory disease intervention can inhibit the inflammatory mediator secretion, apoptosis and regulate the immune cell function.展开更多
