The expression of proliferating cell nuclear antigen (PCNA) was studied in 50 cases of squamous cell carcinoma of the skin using immunohistochemistry and PCNA cyclin monoclonal antibody. PCNA staining was found in the nuclei of tumour cells, two types of staining were seen, a granular pattern and a more diffuse nuclear staining. The expression of PCNA showed a significant positive correlation with degrees of differentiation of the carcinoma cells and lymph node metastasis (P

The expressions of p53 protein, PCNA and macrophage count in 50 cases of skin squamous cell carcinoma were studied by LSAB immunostaining of monoclonal antibodies (PC-10, CD68 and Do-7). The relationship between the proliferation of cancer cell and the count of stroma macrophage to the degree of differentiation was studied and observed in situ. The results showed that the positive rates of expression of both p53 protein and PCNA in the squamous cell carcinoma were 56% and 100%, respectively. The distribution and strength of the expression of p53 protein and PCNA were positively correlated to the degree of cell differentiation. Macrophoge regularly located in the margin of cancer nest. The macrophage count was reversely correlated to the degree of differentiation. It is concluded that the degree of differentiation is parallel to the expression of p53 protein and PCNA, whereas, the macrophages in the stroma to some extent inhibits the cancer cell proliferation.

The skin organ model can be cultrured in ways of organ culture and organotypic raft culture It can be used in skin transplantation,pharmacy or investigate the mechanism of pigmentation. Though there are many ways in culturing skin organ model,how to further improve technology to produce more similar to human's skin organ,and put it in treating dermatosis still needs further exploring. The model of skin organ provides a good platform for new drug development,toxicology experiment and physiological function research. Some tissues engineering skin products have been approved by Food and Drug Administration in America for clinical use. It is believed that following the development of tissue engineering and relative subjects,skin organ culture model in vitro will become one of the effective means on dermatosis study.

[Objective]This study was aimed to research the synergistic antitumor proliferation effects and their best proportion of ursolic acid(UA) and tetrandrine(Tet), a pair of compounds isolated from Chinese herbs which showed complement inhibition on the multiple signal pathways. [Methods] The reporter assays on tumor-related signal pathways for MAPK/ERK, MAPK/JNK, NF-κB, Wnt, Notch, Cell Cycle, Myc/Max and Hypoxia were used to study the effect of five different Chinese herbal compounds on tumor proliferation,it was concluded cepharanthine(Cep), Tet, 18α-glycyrrhetinic acid(18α-Gly), UA and luteolin(Lut). MTT assay and crystal violet staining were used to study the antiproliferative effect of 15 different compounds for the tumor cells of MDA-MB-231,SW480,MG63,PC3,DU145,HCT116,143B and MDA-MB-468, which is consisted with Cep, Tet, 18α-Gly, UA and Lut for the 15 different compounds. Coefficient of drug interaction(CDI) method was used to detect the synergistic effect of the two compounds. Combination of index(CI) and isobologram method was used to screen the best ratio of compounds in their antiproliferative effects. [Results] The signal pathway reporter assay showed that UA and Tet could complementarily inhibit tumor-related signaling pathways. And the results also showed that UA and Tet could induce synergetic anti-tumor cell proliferation in vitro. Furthermore, the optimal ratio of UA and Tet was 9:1 by using isobologram and CI method. [Conclusion] UA and Tet can be inhibited and complemented by 8 tumor-related signaling pathways, and we used MTT assay and crystal violet staining or other methods to confirm the synergistic antitumor proliferation effects, furthermore, the optimal proportion for UA and Tet were screened, and it provided a new insight to develop new anticancer formula in research.
