A patient with pure alexia after occipital lobe and splenium infarction was investigated systematically in cognition and speech. It suggested that the damage of the route from orthographic processing to mental lexicon might cause reading disability, that meant the patient can not extract the phonological and semantic information from the mental lexicon. This patient presented some visual perception disorder, but the significance of visual perception still needs further research.

The studies of the pathogenesis of alexia in the west were based on the alphabetic writing system. Chinese is a meaningful writing system, which has its own characteristic of orthographic, semantic and phonological. In recent years, with the development of cognitive neuropsychology, the researchers have investigated the Chinese alexic patients, revealed the special clinical feature of Chinese alexia, and discussed the pathogenesis of it. This article would review the advance of Chinese alexia.

Objective To observe the effect of Melodic Intonation Therapy on severe aphasia.Methods Additionally to the stimulus therapy,familiar songs were used in the treatment of listening,retelling and naming in 12 cases.Results The patients showed improvement in listening,retelling and naming.Conclusion Using familiar songs in the treatment can promote the recovery of aphasic patients.

OBJECTIVE:To explore ways to resolve the quality problems of Chinese herbal slice so as to provide reference for producers,processors and users.METHODS:The records of check and accept prepared slice into storeroom in our hospital during 2008 were summed up and sorted out.The number of total batches,the number and proportion of unqualified batches were calculated to analyze the causes of unqualified slice after checking.RESULTS:In 2008 there were 4 519 batches of herbal slice while 94 batches were unqualified and accounted for 2.1% in total.53 batches were refused because of their quality problem,accounting for 56.4% of unqualified batches.CONCLUSION:It is urgent to improve the quality of prepared slice and standardize the processing of herbal slice.

Objective To get the thresholds of single and simultaneously multiple bone conduction auditory steady-state response(BC-ASSR) of young adults with normal hearing,and to compare the thresholds obtained with the two methods.Methods BC-ASSR to single and simultaneously multiple stimuli and PTA were examined in 28(56 ears ) young adults with normal hearing.Results At 0.5,1,2,4 kHz,the thresholds of BC-ASSR to single stimuli were 53,47,53,51 dB SPL respectively;the thresholds of BC-ASSR to simultaneously multiple stimuli were 59,54,63,61 dB SPL respectively.There were significant differences between the two at each frequency. Conclusion There are some difference between the thresholds of ASSR to single and simultaneously multiple bone conduction stimuli,especially at the higher frequencies.

Object To study the influence of drought stress on imbibition germination of Glycyrrhiza uralensis seed and the drought resistance of its seedling. Methods To measure the imbibition rate, germination rate, seedling growth, relative tissue moisture content, relative electrical conductivity, SOD enzyme activity under drought stress simulated by PEG-6000. Results The imbibition rate, germination rate, SOD enzyme activity, and seedling growth present rising tendency then following by the decrease, while the relative tissue moisture content and the relative electrical conductivity tend to decrease. Conclusion The appropriate drought stress increases both the G. uralensis seed germination rate and the seedling drought resistance.

目的：对完全性失语的患者经言语治疗后的结果进行分析。研究方法：对10 例完全性失语患者进行筛查，采用中国康复研究中心失语症检查及头颅CT、MRI确诊为完全性失语，并对患者进行语言治疗。结果：10 例患者中5 例有改善，并且在发病后7－12个月比发病后的前6 个月恢复得快。结论：完全性失语的患者经言语治疗后可在一定范围内得到恢复，但要达到日常生活交流必须借助辅助交流。本文同时就完全性失语的定义、言语特征及预后进行讨论。
