这段是我改过的：

Lin Liu told the Science Journal that she felt the patients looked spiritless and were living in pain. They did not know their diseases could not be cured even at the best hospitals in Beijing. So when they saw the advertisement (news report?) of the Xiao Procedure on CCTV - the Chinese Central TV station, the official TV media run by the central government of China, they did not give it a second thought. They would trust the reputation of Zhengzhou University and their experts too.

好像中央台的宣传是报道而不是广告吧？
