Objective To investigate the effect of telerehabilitation on memory disorders. Methods From August, 2010 to April, 2015, 81 patients with memory disorders were randomized into control group (n=26), computer-assisted training group (n=33) and telerehabilita-tion training group (n=22). All the patients accepted medicine to facilitate the recovery of memory. Besides, the computer-assisted training group and the telerehabilitation training group accepted memory-based training programs with cognitive rehabilitation system locally or on network respectively, for six weeks. They were evaluated with Wechsler Memory Scale, Rivermead Behavioural Memory Test-2nd Edition and Rey Auditory Verbal Learning Test before and after training. Results Both computer-assisted and telerehabilitation training groups im-proved in all the assessment after training (t>4.059, P<0.001). There was no significant difference between them (P>0.05). There was no sig-nificant improvement in the control group after training (t<0.771, P>0.05). Conclusion Memory rehabilitation training can significantly im-prove memory abilities, similar with locally or telerehabilitation system.

Objective To investigate the effect of rehabilitation on memory deficits after acquired brain injury, to compare different training models of memory rehabilitation and to analyze the possible factors affecting memory rehabilitation. Methods 144 patients with acquired brain injury following memory deficits were randomly assigned to computer-assisted training group, face-to-face training group and control group. Both training groups were given memory-based cognitive training program once a day which sustained 30 minutes for 6 or 12 weeks. The instantaneous memory, short-term memory and long-term memory were evaluated and compared before and after training. The effect of gender, age, education, course, site of injury and coma time on training efficacy were analyszed as well. Results 6 weeks and 12 weeks at training, both computer-assisted and face-to-face training groups showed a significant improvement in memory abilities when compared to controls (P<0.01), with the former making more progress (P<0.01). Negative correlation was found between age and memory performance. Conclusion Effectiveness of memory rehabilitation is proven. 12 weeks training can significantly improve memory. Cognitive training using professional equipment is significantly more effective than the face-to-face training and should be recommended.

ObjectiveTo analyze the production of Poria in 5 major producing areas and the problems through field investigation and literature review and thus to lay a foundation for healthy development of Poria industry. MethodEach production process of Poria in Anhui， Hubei， Hunan， Yunnan， and Sichuan was probed and related research was retrieved for the analysis. ResultSichuan， Guangxi， Guizhou， and other areas have been the emerging producers of Poria. However， a few Poria cocos lines were used and the variety breeding lagged behind. Different cultivation techniques were adopted in different production areas. For example， the "induction" method failed to be widely used. Moreover， the harvest time was mainly dependent on the market demand not matter it was suitable or not. Furthermore， steaming has replaced the traditional diaphoretic processing in the processing of this medicinal material in production areas. In addition， fumigation with sulphur was still used in the processing of Poria. ConclusionAn excellent variety is the key to the quality of Poria. Efforts should be made to strengthen the evaluation of the germplasm resources of P. cocos and variety breeding and standardize the processing in production areas， thereby ensuring the safety and effectiveness of Poria and the decoction pieces. In addition， the contradiction between artificial cultivation and woodland ecology should be fully coordinated to ensure the sustainable development of Poria industry in China.
