BEIJING, Dec. 9 (Xinhua) — The following is a summary of published science and technology news of China.
LIVE CLASS FROM SPACE
A special lecture kicked off Thursday afternoon at China’s space station, given by the Shenzhou-13 crew members Zhai Zhigang, Wang Yaping, and Ye Guangfu to students on Earth.
After introducing their living and working scenes in the space station, they began to demonstrate science experiments. They also have real-time Q&A with the students via video call, according to the China Manned Space Agency.
GENE-EDITING DELIVERY TOOL
Chinese scientists have developed a targeted delivery system that can bring gene-editing tools to colon cells, offering a precise cure for inflammatory bowel disease.
The study, published on Thursday in the journal Science Advances, reported a CRISPR-Cas9 prodrug nanosystem that can transport a gene-editing protein exclusively to inflammatory lesions in mice colons and then “switch on” the protein.
CHINESE COVID-19 MEDICINES
The National Medical Products Administration (NMPA) has given emergency approval to the registration application of two COVID-19 medicines, BRII-196 and BRII-198.
This is China’s first approved COVID-19 virus-neutralizing antibody combination therapy with independent intellectual property rights.
The two medicines are used in combination to treat adult and adolescent patients with mild and moderate symptoms and with severe risk factors for progression, according to the NMPA. Specifically, the medicines are conditionally approved for adolescents ranging from 12 to 17 years of age with a body weight greater than 40 kg.
