糖皮质激素在SARS、MERS治疗中的应用进展及对COVID-19治疗的启示

采用局部通风为主、屋顶全面通风为辅的方式对某铁路车辆检修焊接车间进行烟尘危害治理。分别在治理前后，对车间的电焊烟尘、砂轮磨尘、其他粉尘进行时间加权平均浓度、短时间接触浓度的检测。治理前各粉尘浓度均不同程度超标，治理后全部达标，且所有岗位治理前后粉尘浓度差异均有统计学意义（户＜0.05）。工业物联网技术的利用在烟尘危害控制自动化、远程化、可视化上有所提高。

Advances of corticosteroids therapy in SARS and MERS and implications for COVID-19

COVID-19 is an emerging acute infectious diseases in respiratory tract. The pathogen of COVID-19, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) is all coronavirus. There is no specific antiviral drugs for COVID-19 at present.
