Observational Study[The influence of serum magnesium level on the prognosis of critically ill patients].
To investigate the incidence of hypomagnesemia and the effect of serum magnesium levels on the prognosis of critically ill patients in intensive care unit (ICU). ⋯ Serum magnesium levels are closely related to mortality rate in patients in ICU, so more attention should be paid to the occurrence of hypomagnesemia in critically ill patients.

[The role of pulse oximetry plethysmographic waveform monitoring as a marker of restoration of spontaneous circulation:a pilot study].
To investigate the feasibility of using pulse oximetry plethysmographic waveform (POP) to identify the restoration of spontaneous circulation (ROSC) during cardiopulmonary resuscitation (CPR). ⋯ Analysis of POP using time and frequency domain methods could not only quickly detect cardiac arrest, but also show a role as a feasible, non-invasive marker of ROSC during CPR.

[Effect of pre-arrest and post-arrest mild hypothermia on myocardial function of ventricular fibrillation after restoration of spontaneous circulation in rabbits].
To study the effect of pre-arrest and post-arrest mild hypothermia after restoration of spontaneous circulation (ROSC) on myocardial function, ultrastructure, apoptosis of myocardial cells in rabbits with ventricular fibrillation. ⋯ Our study shows that mild hypothermia has no effect on ROSC rate. Pre-arrest hypothermia can ameliorate myocardial systolic function of rabbit in early stage after ROSC, and it has no negative influence on diastolic function. Post-arrest mild hypothermia produces no negative influence on myocardial function of rabbit, but it improves 48 hours survival rate in ROSC rabbits. Both pre-arrest and post-arrest mild hypothermia therapy can attenuate myocardial injury in CA model of rabbits by ameliorating mitochondrial injuries and suppressing apoptosis of myocardial cells.

[Effects of Shenfu injection on the expression of transcription factors T-bet / GATA-3 in pigs with post-resuscitation myocardial dysfunction].
To examine whether Shenfu injection (SFI) reduces post-resuscitation myocardial dysfunction in a pig model by modulating expression imbalance of transcription factors of regulatory T cell, namely GATA-3 and T-bet. ⋯ Myocardial immune dysfunction is induced by Th1/Th2 imbalance following myocardial injury subsequent to CPR in pigs. SFI can attenuate myocardial injury and regulate myocardial immune disorders, protect post-resuscitation myocardial injury by modulating expression imbalance of transcription factors GATA-3 and T-bet.
