Paralysed policeman Jacky Chu Chun-kwok has checked into a Guangzhou hospital for oxygen pressure treatment to help him regain partial use of his limbs. Accompanied by his wife Chu Choi Yin-ping and mother Lee Lai-hing, Mr Chu was taken from Kwong Wah Hospital to the Guangzhou Military District Main Hospital in a mainland ambulance. He was then taken straight to a room on the fourth floor of the high-pressure oxygen or hyperbaric department. 'We have arrived,' Ms Lee called out to her son, who can hear but not respond, as the medical workers prepared to lift him out of the ambulance. Mr Chu was left paralysed after being stabbed in the neck while on patrol last year in Cheung Sha Wan. His wife, who was smiling and clutching a doll her husband had bought for her and their daughter, later said that she felt relieved because conditions at the hospital were better than she had expected and the 'entire journey was hassle-free' from Hong Kong to the hospital. She said she hoped the doctors in Guangzhou could at least help her husband to eat on his own and be more responsive. 'Here at least, we can give him high pressure oxygen treatment as well as take traditional Chinese medicine,' she said. Mr Chu had been receiving acupuncture treatment in Hong Kong and that had helped, his wife said. He was also given massage and physiotherapy. A hospital spokesman said doctors would have to examine Mr Chu in the next three days before proposing a treatment regime. 'He has just checked in. We are unable to give you any information before doctors have seen him,' he said. The oxygen cabin can accommodate 12 patients at most and each treatment lasts at least two hours. Mrs Chu said she did not expect the treatment would bring a full recovery but she hoped it would help her husband to some extent. 'I only hope he can eat on his own and have some consciousness to recognise people,' Mrs Chu said. 'The hope is not very big. We will see how much he tries and how much he can recover,' she said. The Hong Kong police force is footing the HK$210,000 needed to cover the cost of Mr Chu's controversial treatment which is not allowed in Hong Kong.
