The computer three-dimensional reconstruction of serial sections is an important research area in the world at precent. In this paper, we combine the computer graphics, image processing and biomedical techniques to reconstruct the stereo model of intra-glandular lymphatics, veins, arteries and duets with the serial semithin sections of human submandibular gland.

AIM:To investigate the expression characteristics of TRIM 27 in human nasopharyngeal carcinoma tissues, nasopharyngeal carcinoma 5-8F cells and NP69 cells, and to observe the effect of TRIM27 on the proliferation, in-vasion and migration of 5-8F cells.METHODS:The levels of TRIM27 in the nasopharyngeal carcinoma tissues and normal nasopharyngeal epithelial tissues were observed by the method of immunohistochemistry .The mRNA and protein levels of TRIM27 in the 5-8F cells and NP69 cells were determined by real-time PCR and Western blot .TRIM27 siRNA was trans-fected into the 5-8F cells with Lipofectamine 2000.The relative mRNA expression of TRIM27 was detected by real-time PCR.The relative protein expression of TRIM 27 was detected by Western blot .The cell proliferation was analyzed by CCK-8 assay and cell colony formation assay .The change of cell invasion was examined by Matrigel invasion assay .The change of cell migration were examined by wound healing assay .RESULTS:The results of immunohistochemistry showed that the protein expression of TRIM27 in the nasopharyngeal carcinoma tissues was obviously higher than that in the normal nasopha -ryngeal epithelial tissues .The results of real-time PCR and Western blot showed that the mRNA and protein levels of TRIM27 in the 5-8F cells were obviously higher than those in the NP69 cells.The abilities of proliferation, invasion and migration in the 5-8F cells were significantly suppressed after TRIM27 gene silencing ( P <0.05).CONCLUSION:TRIM27 acts as a oncogene in the 5-8F nasopharygeal carcinoma cells .The abilities of proliferation , invasion and migration are significantly suppressed after TRIM27 gene silencing in the 5-8F cells.
