Objective:To study the neuropsychological features and explore possible mechanisms in pure word deafness.Methods:A case of a 55 year-old right-handed woman was analysed,who presented with a long lasting pure word deafness following subcortical and cortical hemorrhage in right temporal and parietal lobe.Results:There was no sign of aphasia. The auditory deficit was sepecific for language, while recognition of music and environmental sounds was normal. CT examinations showed that the lesion was due to right cerebral hemisphere hemorrhage, mainly the white matter of temporal and parietal lobe. Conclusion:It is proposed that pure word deafness was consequent to the isolation of Wernicke's area from incoming auditory information due to the interruption both of the association fibers from the right auditory area traveling across the corpus callosum and of the left auditory radiations.

Objective To guide bracing treatment for adolescent idiopathic scoliosis (AIS). Methods A total of 68 AIS patients with apex vertebrae (AV) under T6 had received the improved Cheneau bracing treatment between March 2008 and June 2010. All patients were divided into two groups. There were 16males and 35 females, with a mean age of 13.6 years (range, 10.6-17.2) in the intervention group. The mean Cobb angle was 29.5° (range, 20°-38°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the group;while there were 6 males and 11 females, with a mean of 13.2 years (range, 10.8-16.8) in the control group.The mean Cobb angle was 28.7° (range, 20°-37°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the control group. All patients in control group were informed standardized bracing treatment method. But we gave patients in intervention group two copies of "The Form of Guiding Bracing Treatment" treatment of patients with AIS, and informed that they carried out the bracing treatment according requirement of the form.Cobb angle was measured before the treatment and at 6th, 12th, 18th month after treatment. Results Sixtyfive cases were followed up for 18-27 months. However, one female in control group and two females in intervention group were lost during follow-up. Coefficient and intraclass correlation coefficient of form were both over 0.60. The acceptance rate of the table was 97.54%(199/204), qualified rate was 100.00%( 199/199), and with good content validity. The mean Cobb angle decreased gradually from 28.71° to 25.76° in control group and from 29.47° to 21.59° in intervention group. Four cases in control group and 34 cases in intervention group had reduced more than 5° at 18 months after treatment. There was significant difference regarding Cobb angle between two group. Conclusion The form of guiding bracing treatment has good reliability and validity and can guide bracing treatment of AIS correctly and effectively.

Objective To summarize the clinical experience of laparoacopic cholecystectomy(LC) for acute cholecystitis. Methods LC was performed in 68 cases of acute cholecystifis for 2004 to 2007. The operation was completed under CO2 pneumoperitoneum by using 4-port technique. Results The LC was successfuUy accomplished in 64 cases, while a conversion to open surgery was required in 4 cases. A drainage tube at the foramen of Winslow was placed in 1 cases. Conclusion Strict adhesion to surgical indications of LC, standard performance of the proce-dure, timely conversion to open surgery, and proper placement of drainage tube are key factors to ensure a successful operation.
