Three groups (childhood autism, mental retardation and normal control) were used to test the reliability and validity of the new screening tool. Results: The checklist had satisfying reliability including good inter-rater reliability, test-retest reliability, split half reliability and internal consistency. The differential validity of the checklist and the differential diagnostic validity of the items were good, so as the construct validity and the criterion validity. The cut-off point for screening and diagnosis were 21 and 24 respectively. Conclusion: The childhood autism checklist has good reliability and validity, and fit for the situation of Chinese children with the disorder.

Proteome research has become a new hot spot in the post-genome era. High-resolution two-dimensional gel electrophoresis (2-DE), which provides the most comprehensive analysis system of the whole proteome, was highly improved in recent years. With the development of computer techniques, the powerful and user-friendly image analysis systems appeared to help high-throughput, large-scale proteomic studies. Using new generation two-dimensional image analysis software, ImageMaster 2D Elite, the 2D gels of proteins extracted from cultured Schwann’s cells were processed. The analysis procedure, including image acquirement, spot detection, match, background subtraction, pI/Mr calibration, analysis results report and database query, were reported and discussed.
