title: [Expression of P21 and P185 in benign and malignant epithelia of cheek mucosa].
abstract: To analyze the expression of P21 and P185 in normal epithelia, chronic non-specific inflammatory epithelia, squamous cell carcinoma and epithelia immediately adjacent to carcinoma of cheek mucosa, immunohistochemistry technique and image analysis technique were used. The results showed: there was excellently higher expression of P21 and P185 in squamous cell carcinoma and epithelia immediately adjacent to carcinoma than in normal and inflammatory epithelia of cheek mucosa, which were compactly correlative.
