Clinical effect and mechanism of total glucosides of paeony in the adjuvant therapy for children with Henoch-Schönlein purpura nephritis: a prospective randomized controlled study / 中国当代儿科杂志

OBJECTIVE@#To study the clinical effect and mechanism of total glucosides of paeony (TGP) in the adjuvant therapy for children with Henoch-Schönlein purpura nephritis (HSPN).@*METHODS@#Sixty-four HSPN children with moderate proteinuria were divided into a TGP treatment group (@*RESULTS@#Compared with the healthy children before treatment, the children with HSPN had higher proportion of Tfh cells and expression levels of IL-21 and IL-4 (@*CONCLUSIONS@#TGP has a marked clinical effect in the treatment of HSPN and can reduce the inflammatory response of the kidney and exert a protective effect on the kidney by inhibiting the proliferation of Tfh cells and downregulating the expression of IL-21 and IL-4 in plasma.
