The Chinese hospital treating cancer-stricken Nobel laureate Liu Xiaobo offered a grim update on his health Wednesday, but human rights groups cautioned that the authorities may be manipulating the medical reports- The 61-year-old democracy advocate’s liver function continued to deteriorate and he suffered from “shock and organ failure,” according to the First Hospital of China Medical University in the northeastern city of Shenyang. The hospital’s website has been giving regular updates about Liu’s condition since he was admitted early last month after he was transferred from prison due to late-stage liver cancer.
