[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.

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.

[Impacts of sepsis-induced myocardial dysfunction on hemodynamics, organ function and prognosis in patients with septic shock].
To investigate the impacts of sepsis-induced cardiac dysfunction on hemodynamics, organ function and prognosis in the patients with septic shock. ⋯ Sepsis-induced myocardial dysfunction is a reversible organ dysfunction. It can directly induce decreased left ventricular systolic function and enlargement of ventricle in patients with septic shock without reducing cardiac output or impairing the functions of other organs, or elevating the mortality rate.

[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.
