The concept of white matter dementia was first introduced by Filley in 1988.It was found following behavioral neurologica researches that patients with this type of dementia manifested the dysfunctions of sustained attention,memory retrievial,frontal lobe and visualspatial function.They also had psychiatric manifestations but language and extrapyramidal function remained normal.10 diseases of white matter disorders are listed for understanding the clinical characteristics of this type of dementia.

Objective:To explore the relationship between the expression of EGFR and STAT3 in human la-ryngeal papilloma and its biological behavior. Method: Reverse transcription polymerasechain reaction(RT-PCR), immunohistochemical staining and Western blot were used to evaluate the mRNA and protein expression of EGFR and STAT3(p-STAT3) in 42 laryngeal papilloma tissues and 15 samples of normal laryngeal tissue, and the rela-tionship between the protein expression of them and clinicpathological parameters was also analysized. Result: The mRNA expression levels of EGFR and STAT3 in laryngeal papilloma tissue were significantly higher than that in normal laryngeal tissue(P<0.05,P<0.01). Protein positive expression of EGFR and p-STAT3 were also detected in a significantly greater proportion of laryngeal papilloma than normal laryngeal tissue by immunohistochemistry and western blot(P<0.01,P<0.05). There was relationship between EGFR and p-STAT3 overexpression in la-ryngeal papilloma(P<0.05). The expression p-STAT3 was correlated with the recurrence and canceration of la-ryngeal papilloma(P<0.05). Conclusion: The EGFR-STAT3 signal transduction pathway may be involved in the pathogenesis of laryngeal papilloma,, and the persistent activation of STAT3 gene plays an important role in the recurrence and canceration of laryngeal papilloma.
