ABSTRACT
<p><b>OBJECTIVE</b>To investigate whether Shen-Fu Injection (, SFI) reduces post-resuscitation immune dysfunction in a porcine model of cardiac arrest by modulating apoptosis of regulatory T lymphocytes (Treg) in the spleen.</p><p><b>METHODS</b>After 8-min untreated ventricular fibrillation and 2-min basic life support, 24 pigs were divided into 3 groups with a random number table, i.e. SFI group, epinephrine (EP) group, and saline (SA) group (8 in each group), which received central venous injection of SFI (1.0 mL/kg), EP (0.02 mg/kg) and SA, respectively. The same procedure without CA initiation was achieved in the sham-operated (sham) group (n=6). After successful return of spontaneous circulation (ROSC), apoptosis rate of splenic Treg was detected by flow cytometry; and the mRNA expression of forkhead/winged helix transcription factor (Foxp3) of splenic Treg was detected by real time-polymerase chain reaction; and the levels of interleukin-4 (IL-4) and interferon-γ (IFN-γ) in porcine splenic Treg were detected by using enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>Compared with the sham group, the apoptosis rate of Treg was significantly decreased, and the levels of Foxp3 mRNA expression, IFN-γ, IL-4 and IFN-γ/IL-4 were increased in the SA group (P<0.05 or P<0.01). Compared with the EP and SA groups, SFI treatment increased the apoptosis rate of Treg and reduced the levels of Foxp3 mRNA expression, IFN-γ and IFN-γ/IL-4 (P<0.05).</p><p><b>CONCLUSIONS</b>SFI has signifificant effects in attenuating post-resuscitation immune dysfunction by modulating apoptosis of Treg in the spleen.</p>
