Effects of smilax bockii warb polysaccharide on inflammatory mediators, apoptosis and immune cell function in rats with chronic pelvic inflammatory disease

摘要

Objective:To study the effects of smilax bockii warb polysaccharide on inflammatory mediators, apoptosis and immune cell function in rats with chronic pelvic inflammatory disease.Methods:Female SD rats were chosen as experimental animals and divided into control group, pelvic inflammation group and smilax bockii warb group, pelvic inflammation group and smilax bockii warb group were made into pelvic inflammation models, and smilax bockii warb group were given intragastric administration of smilax bockii warb. 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.
