First we first establish the apoptosis of related protein glossary database, then downloads the neurodegenerative disorders of apoptosis related abstract from the on-line biomedicine literature , and searchesfor the protein information database of the neurodegenerative disorders of apoptosis related pathway, then uses the data mining technology,with apoptosis of protein related glossary database use already establishment. Automatically searches for the neurodegenerative disorders of apoptosis related protein by the program in the biomedicine literature abstract separately in,(1) a sentence,(2) two sentences,(3) aliterature, finding simultaneously appears protein-protein interation. And comparing to the neurodegenerative disorders of apoptosis related protein database, looking for their repetition. This result comparing to the known neurodegenerative disorders of apoptosis related pathway, thus looking for unestablished neurodegenerative disorders of apoptosis pathway.

The results showed that the changes of the types were not caused by new cell mutation, but by translocation of the different cell types of variegation. The changes of division direction of white cells and green cells resulted that some of the green epidermal cells translocated into the second layer and it pushed furthermore the origin white cells of the second layer into the third layer, so that the variegation altered.
