Practice and System Construction of Telemedicine for Coronavirus Disease 2019 Epidemic Prevention and Control / 中国医学科学院学报

Telemedicine is one of the five key components of the "Internet Plus Healthcare".Due to its high speed,real-timeness,low cost,and wide spread,telemedicine is highly feasible in the prevention and control of major infectious diseases.This article introduces the practiceof telemedicine in Peking Union Medical College Hospital during the cornavirus disease 2019(COVID-19)epidemic,during which the network resources were applied to break geographical restrictions and resolve communication barriers between hospitals and departments.This article summarizes the telemedicine application before,during and after COVID-19 control and elucidates how to build a telemedicine prevention and control system for infectious diseases,with an attempt to further improve telemedicine and is application in the public health emergency system in China.

Inhibitor of DNA-binding-1/inhibitor of differentiation-1 (ID-1) is implicated in various aspects of gastric cancer cell biology.

In order to determine the biological roles of the inhibitor of DNA-binding-1/inhibitor of differentiation-1 (ID-1) protein in MGC803 and AGS cell lines, we ectopically expressed or downregulated ID-1 in the both gastric cell lines and measured various parameters of tumor cell development, including cell proliferation, cell cycle progression, apoptosis and cell migration. The ectopic expression of ID-1 significantly enhanced cell proliferation, cell cycle progression and cell migration, and protected MGC803 and AGS cell lines from cisplatin-induced apoptosis. The opposite effects were observed after downregulation of ID-1, which in combination with cisplatin treatment enhanced apoptosis in a synergistic fashion. Collectively, these findings demonstrate that ID-1 plays pivotal and diverse roles in the biology of certain gastric cancer cells, further suggesting that ID-1 is implicated in the pathogenesis and progression of gastric cancer.
