Abstract:
Objective To study Xuebijing(XBJ,a Chinese herbal preparation)on heat shock protein 70(HSP 70)in rats with severe acute pancreatitis(SAP).Methods Sixty healthy male SD rats were randomly(random number)and equally divided into sham operation group(A),SAP group(B),SAP with low-dose XBJ(4 ml/kg)intervention group(C)and high-dose XBJ(8 ml/ kg)intervention group(D).The SAP model was made by retrograde infusion of 5 ％ sodium taurocholate into the bilepancreatic duct.The rats in group C and group D were treated with 4 ml/kg XBJ and 8 ml/kg XBJ injected intraperitoneally and the treatment repeated once 12 hours later.Rats were sacrificed separately 6 h,12 h and 24 hours after modeling with/without XBJ and the blood samples were collected.Serum HSP 70 and cytokines TNF-α,IL-1β,IL-6 levels were measured by using enzyme-linked immunosorbent assay (ELISA); and correlation between serum HSP 70 and cytokines was analyzed.Results Levels of serum HSP 70 and TNF-o,IL-1β,IL-6 did not change significantly in rats of group A.Compared with group B,levels of serum HSP 70 and TNF-α,IL-1 β,IL-6 in all blood samples were lower significantly in groups C and D,and levels of those biomarkers decreased much more in group D than those did in group C.Thelevels of serum HSP 70 were positively correlated with cytokines TNF-α,IL-1β and IL-6(P ＜ 0.05).Conclusions Levels of serum HSP 70 in rats with SAP increased significantly.XBJ could reduce serum HSP 70 level in rats with SAP,and this may be the mechanism of the anti-inflammatory effects of XBJ.
