Objective To evaluate the validity and reliability of the Chinese version of Alcohol Withdrawal Scale (AWS). Methods Totally 175 patients diagnosed as alcohol dependence according to the criteria of ICD-10 were studied. Intraclass correlation coefficient (ICC) analysis was applied for examining interrater consistency and Cronbach' s α for internal consistency. Factor analysis was used to examine the construct validity. Correlation analysis between AWS and CGI,Revised Clinic Institute Alcohol Withdrawal Syndrome Scale(CIWA-Ar) were conducted to evaluate the criterion validity. Based on clinical criteria,ROC curve was calculated so as to test the discriminative ability and establish the cut-off point of the scale. Results ( 1 ) Reliability: ICC value was 0.93,and Cronbach's α was 0.83,which indicated good interrater and internal consistency. (2) Validity:the correlation coefficients of the two subscale with the total scale score were 0.78,0.83 respectively. The correlation coefficients between the subscale were 0. 81 and factor analysis revealed that each item of the scale had relatively high load on the primary factor (0.409 ~0.926). At the time of admission,the total score of the AWS was positively correlated with that of CGI ( r = 0.71, P < 0.05 ). The total score of the AWS also was positively correlated with that of CIWA-Ar ( r = 0. 86, P<0. 05). As treatment went on,total score of the AWS showed a downward trend,at the end of the first week,the total score of the AWS was positively correlated with that of CGI ( r = 0.62, P<0.05). (3)The cut-off point of AWS for mild alcohol withdrawal state was determined as ≥3. With this cut-off point,AWS had both high sensitivity (92.1% ) and specificity (73.5% ) ,and the area under curve (AUC) was 0. 91. The cut-off point of AWS for moderate withdrawal state was determined as ≥7, and the sensitivity and specificity of AWS were 94.3 % and 89.7 % respectively, with the AUC of 0.94. The cut-off point of AWS for severe withdrawal state was determined as ≥ 10. With this cut-off point AWS had both high sensitivity (94. 9% ) and high specificity (92.6% ) .with the AUC of 0.93. Conclusion AWS has good reliability and validity and can reflect the change of the disease and the efficacy of treatment.

Objective Explore an approach with which stem cell can be used to cure traumatic spinal cord. Methods To better repair spinal cord injury, adult Sprague-Dawley (SD) rat MSCs was isolated and induced to differentiate into neuron-like cells with a Chinese medicine, Musk's polypeptide named Musk-1 in vitro and be seeded into microsurgical transectional model of adult rat spinal cord with cell differentiation and transplantation techniques. Results After cell transplantation, animals seeded with the rMSCs-derived neuron-like cells promoted significant improvement in function after spinal cord (P<0.05,effective observation for 90 days ) when compared to the lesion-control group. Histology and immunocytochemical analysis confirmed a large number of rMSCs-derived neuron-like cells survived well in the transplantation zoon and numerous cells migrated within the host adjacent tissues as far as 6millimeters above and below the border of the lesion. Fluorescence gold retrograde tract tracing analysis revealed the positive motor neuron of fluorescence gold mark was found in the head side of rat spinal marrow ,corpus rubrum ofmesencephalic and corticospinal tract fibers. This suggested that corticospinal tract fibers of spinal cord area got regeneration and passed through the lession to reach the tail of spinal marrow.Conclusion These findings demonstrated that "pre-programmed" rMSCs can survive, migrate, integrate as well as restore spinal function and behavior in the microsurgical transectional model of rat spinal cord, and may serve as a suitable approach to traumatic spinal cord injury.
