摘要
Objective:To investigate the action of Shen-Fu Injection(参附注射液,SFI) in regulating the expression of the serum complements and inflammatory cytokines synthesized and released in response to the stress of global ischemia accompanying cardiac arrest(CA) and resuscitation.Methods:Thirty pigs were randomly divided into the sham(n=6) and 3 returns of spontaneous circulation(ROSC) groups(n=24).After 8-min untreated ventricular fibrillation and 2-min basic life support,24 pigs of the ROSC groups were randomized into three groups(n=8 per group),which received central venous injection of SFI(SFI group),epinephrine(EP group),or saline(SA group).Hemodynamic status and blood samples were obtained at 0,0.5,1,2,4,6,12,and 24 h after ROSC.Results:Serum concentrations of specific activation markers of the complement system C3,C4 and C5b-9 were increased during cardiopulmonary resuscitation th rough1 24 h after ROSC.There were intense changes of various pro-inflammatory cytokines and anti-inflammatory cytokines as early as 0.5 h after CA.Compared with the EP and SA groups,SFI treatment reduced the proinflammatory cytokines levels of interleukin(IL)-6,IL-8and tumor necrosis factor α(TNF-α,P<0.05),and increased the anti-inflammatory cytokine levels of IL-4 and IL-10(P<0.05).Further,SFI treatment decreased the values of C3,C4 and C5b-9 compared with the EP and SA groups.Conclusions:SFI,derived from the ancient Chinese medicine,has significant effects in attenuating post-resuscitation immune dysfunction by modulating the expression of complements and cytokines levels.The current study provided an experimental basis for the clinical application of a potential pharmacologic target for post resuscitation immune dysfunction.
