Objective To investigate the protective effective mechanism of Fleabane on PC12 cells impaired by hypoxia-reoxygention (HR).Methods The PC12 cells cutured in vitro were grouped as following:normal control (NC) group, the HR group,Fleabane 10?mol/L (E1)group, 20?mol/L (E2)group, 30?mol/L (E3)group. The livability of PC12 was measured after impaired by HR in groups HR and E1～E3. The expressions of Bcl-2 and Bax were also detected by Western Blot. Results (1)Compared with NC group,the survival rate of PC12 decreased in HR group(P

The outbreak of coronavirus disease 2019 (COVID-19) was declared a global public health emergency on 31 January 2020. Emergency medicine procedures in Emergency Department should be optimized to cope with the current COVID-19 pandemic by providing subspecialty services, reducing the spread of nosocomial infections, and promoting its capabilities to handle emerging diseases. Thus, the Chinese Society of Emergency Medicine and Wuhan Society of Emergency Medicine drafted this consensus together to address concerns of medical staffs who work in Emergency Department. Based on in-depth review of COVID-19 diagnosis and treatment plans, literatures, as well as management approval, this consensus proposes recommendations for improving the rationalization and efficiency of emergency processes, reducing the risk of nosocomial infections, preventing hospital viral transmission, and ensuring patient safety.
