[Abstract]:Objective: 1. To study the expression and significance of Np63 in normal skin, psoriasis vulgaris, seborrheic keratosis, sunlight keratosis and basal cell carcinoma. 2. To investigate the value of Np63 in the diagnosis and differential diagnosis of benign and malignant proliferative diseases of skin. Experimental methods: In the past two years, 30 cases of psoriasis vulgaris, SKK, AKK, BCCs and BCCs were collected from the dermatology department of the first affiliated Hospital of Kunming Medical University, which met the diagnostic criteria. Normal Skin)10 cases of normal skin were selected from dermatological surgery room and maxillofacial surgery. After dehydration, embedding and slicing, immunohistochemical SP method was used to stain the sections with Np63, and then the sections were observed under optical microscope. Five discontinuous visual fields were randomly selected from each slice in the skin lesion tissue. OLYMPUS BX51 microscopic image acquisition system was used to take pictures, and Image-Pro plus 6.0 / IP) image analysis software was used to quantitatively measure the mean optical density of positive expression in each visual field. Finally, the difference of disease species was analyzed by spss17.0 software. The negative control group: PBS replaced the first antibody and the result was negative. Experimental results: 1. Np63 positive expression was found in 30 cases of seborrheic keratosis and 30 cases of basal cell carcinoma in 10 cases of normal skin and 30 cases of psoriasis vulgaris. In normal skin group, Np63 was mainly expressed in the nuclei of epidermal basal cells and proximal basal cells, while in psoriasis vulgaris and sunburn keratosis, ANp63 was mainly expressed in the nuclei of 1 / 3 cells in epidermal basal layer and lower layer of spinous layer. In seborrheic keratosis group, Np63 was mainly expressed in the nucleus of basal layer and spinous layer of epidermis, and ANp63 was expressed diffusely in the mass composed of basal cell in basal cell carcinoma group. 2. According to IPP software statistics, The average optical density of Np63 in normal skin group was 0.0056 鹵0.0019, that of solar keratosis group was 0.0262 鹵0.01844, that of psoriasis vulgaris group was 0.0266 鹵0.0100, and that of seborrheic keratosis group was 0.0266 鹵0.0100. The optical density was 0.0391 鹵0.0169 and the average optical density in basal cell carcinoma was 0.0498 鹵0.0222. 3. By statistical analysis, the average optical density of Np63 was different or not the same among the disease species, and the difference was statistically significant. There was no significant difference in P0.05 between solar keratosis and psoriasis vulgaris, but there was significant difference between the other two groups. The expression of Np63 was strongest in basal cell carcinoma group, followed by seborrheic keratosis group, psoriasis vulgaris group, sunlight keratosis group and normal skin group. 4. There was no significant difference between the expression of Np63 and the sex, age, location of the disease (exposure and non-exposure) of the patients (P 0.05). The experimental conclusions are as follows: 1. Np63 is closely related to the development and proliferation of basal cells in lamellar squamous epithelium. 2. Np63 can be used as a marker of undifferentiated epithelial-derived tumors. 3. Np63 may be considered as an immunological index for differential diagnosis of seborrheic keratosis and solar keratosis. 4. There was no correlation between the expression of Np63 protein and sex, age and sun exposure.
