Early Warning Factors of Death in COVID-19 Patients.

The infectious coronavirus disease 2019 (COVID-19) has spread all over the world and been persistently evolving so far. The number of deaths in the whole world has been rising rapidly. However, the early warning factors for mortality have not been well ascertained.

MiR-28 inhibits cardiomyocyte survival through suppressing PDK1/Akt/mTOR signaling.

MicroRNAs play critical roles in regulating cell survival under multiple pathological conditions of heart diseases. Oxidative stress-induced apoptosis contributes greatly to heart ischemia-reperfusion injury. Herein, we describe a novel regulatory role of miR-28 on the survival of cardiomyocytes.

Protective effect of propofol and its relation to postoperation recovery in children undergoing cardiac surgery with cardiopulmonary bypass.

The aim of this study was to investigate the effect of propofol and its relation to postoperation recovery in children undergoing cardiac surgery with cardiopulmonary bypass (CPB). Twenty ASA class I-II children with congenital heart disease undergoing cardiac surgery were randomly allocated to a propofol group (n = 10) or a control group (n = 10). Blood samples were collected at five time points: before operation (T (0)), before the start of CPB (T (1)), 25 min after the aorta was cross-clamped (T (2)), 30 min after release of the aortic cross-clamp (T (3)), and 2 h after the cessation of CPB (T (4)).

Comparison of the effects of propofol and midazolam on inflammation and oxidase stress in children with congenital heart disease undergoing cardiac surgery.

Purpose: To investigate and compare the effects of propofol and midazolam on inflammation and oxidase stress in children with congenital heart disease undergoing cardiac surgery.

Materials And Methods: Thirty-two ASA class I-II children with congenital heart disease undergoing cardiac surgery were randomly divided into two groups: propofol combined with low dose fentanyl (PF group, n = 16) and midazolam combined with low dose fentanyl (MF group, n = 16). Tracheal extubation time and length of Intensive Care Unit (ICU) stay were recorded.

[Cardioprotective effects of propofol and midazolam in children with congenital heart diseases undergoing open heart surgery].

Objective: To observe the cardioprotective effects of propofol and midazolam in children with congenital heart diseases undergoing open heart surgery.

Methods: Thirty-two children with cyanotic congenital heart diseases of ASA classes I - II were randomly divided into 2 equal groups: propofol combined with low dose fentanyl group (Group PF) and midazolam combined with low dose fentanyl group (Group MF). The changes of hemodynaics, ECG, SpO2, nasopharyngeal and rectal temperatures were monitored continuously.
