The wife of jailed dissident Xu Wenli has appealed to the authorities to treat her husband's hepatitis as the first anniversary of his imprisonment approaches. He Xintong sent a letter to the authorities on Saturday. Veteran dissident Xu is serving a 13-year sentence at Yanqing prison on the outskirts of Beijing. Xu, one of the founders of the banned China Democracy Party, was sentenced on January 13 for subversion. Ms He said she visited Xu in jail recently but was not allowed to give him some Tibetan medicine to treat hepatitis B. 'I don't understand why they have such prejudice against the Tibetan medicine. Many hospitals recognise the medicine as effective for hepatitis,' she said in Beijing yesterday. Ms He said Xu, 56, was diagnosed in August but doctors said he did not need special medication because his illness was not serious. She added: 'They said he only needed some good rest as his hepatitis cannot be treated quickly. That's not true. He needs medication.' Xu appeared to be in relatively good shape and had been given some medicine for liver trouble, though not the specialised type he needed, Ms He said. He was allowed access to newspapers. Xu recently wrote in a letter he was happy that his daughter, Xu Jin, had graduated from a university in Boston, Ms He said. Ms Xu organised a protest demanding the early release of her father when Premier Zhu Rongji visited Boston in April. Xu was taken on a 'tour' of Beijing in October when prison officials wanted to educate him about the 'transformation' the capital had experienced, his wife reported earlier.
