Objective: To develop the Chinese version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) and evaluate its reliability and validity. Methods: Three investigators assessed 10 dementia cases together with the NPI-Q to evaluate the inter-rater reliability. Eighty-six dementia cases and 30 healthy controls were assessed with the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), the Brief Psychiatric Rating Scale (BPRS) and NPI-Q to evaluate the criterion validity. A subgroup of 30 dementia cases was tested with the NPI-Q again 24 h later to evaluate the test-retest reliability. Results: (1) Internal consistency. Cronbach's a coefficient of the severity subscale was 0.589, mean inter-item correlation coefficient of the severity subscale was 0.107. Cronbach's α coeffi-cient of the distress subscale was 0.612, and the mean inter-item correlation coefficient of the distress subscale was 0.114. (2) Inter-rater reliability. Intraclass correlation coefficient (ICC) of the severity subscale was 0.97, and ICC of the distress subscale was 0.94. (3) Test-retest reliability. The test-retest correlation coefficient of the severi-ty subscale was 0.89, and the test-retest correlation coefficient of the distress subscale was 0.86. (4) Criterion va-lidity. The severity subscale total score was correlated significantly with BEHAVE-AD (r=0.70, P <0.001) and BPRS(r=0.40, P<0.001) total score; the distress subscale total score was correlated significantly with the global ratings in part 2 of BEHAVE-AD (r=0.76, P<0.001) . (5) The severity subscale total score in demen-tia group was significantly higher than that in control group (median: 10 vs.1.5, P <0.001). The distress sub-scale total score in dementia group was significantly higher than that in control group (median: 10 vs 0; P< 0.001) . (6) Exploratory factor analysis identified 4 common factors, including psychosis, abnormal behavior,discontrol and affective symptoms, which explained 58.3% of total variance. All of the items loaded were between 0.596 and 0.803 on their conrresponding factor. Conclusion: The reliability and validity of the Chinese version of NPI-Q meet the psychometrics properties, and deserves to conduct further study in larger samples.

AIM:To investigate the changes of visual development produced by monocular atropinization in rats.
METHODS: Twenty normal SD rats were randomly divided into two groups: control group ( n = 10 ) and atropinization ( experimental) group ( n=10 ) . All the left eyes were selected as the experimental eyes, and the right eyes served as the normal eyes. The left eyes in atropinization group was produced by 1% atropine, 3 times a day and the right eyes in control group was treated with normal saline, 3 times a day. The flash visual evoked potentials ( F-VEP ) and retinoscopy refraction of the rats'both eyes were detected at five time points:0, 7, 14, 21, and 28d after atropinization, respectively. After 28d, six rats were randomly selected from both groups and each group had three rats. The expression of the c- fos mRNA was observed in both visual cortexes. Another six rats were chosen for the same test after 2d dark environment with 2h light later. The expression of c-fos mRNA was detected again.
RESULTS: After 14d anisometropia was observed in experimental group, the difference was 3. 9D ( P<
0.0 5 ) , F-VEP P1 wave of the rats left in experimental group was reached to 88. 9±1. 889ms at 21d, there was statistical difference compared with the right eye ( P<0.05). After 28d, c-fos mRNA expression in the left visual cortex of rats in the experimental group was higher than that of the right side, but there was no significant difference. But when underwent 2h light stimulation after in the darkroom 2d, the c-fos mRNA expression in in the left visual cortex of rats in the experimental group was 5 times higher than that of the right side, there was a statistically significant difference (P<0. 05).
CONCLUSION: In the critical period of visual development, monocular chronic atropine in rats can form anisometropia, may delay the transmission of the optic nerve, hinder the normal development of the visual cortex. Monocular atropinization in rats can be used as the model of anisometropia.
