To compare and analyze the clinical treatment effect of primary pterygium with amniotic membrane transplantation, autologous corneal limbus stem cell transplantation and intraoperative application of 0. 2g/L mitomycin C.METHODS: Retrospective analysis of 232 patients who were underwent primary pterygium surgery was performed. Eighty-two cases were treated with amniotic membrane transplantation, 90 with autologous corneal limbus stem cell transplantation, and 60 with intraoperative application of 0. 2g/L mitomycin C. The postoperative recurrence and complications of three operative methods were compared.RESULTS: The recurrence rate of autologous corneal limbus stem cell transplantation and intraoperative application of 0. 2g/L mitomycin C was lower than that of amniotic membrane transplantation ( P < 0. 05 ). The recurrence rate between autologous corneal limbus stem cell transplantation and intraoperative application of 0. 2g/L mitomycin C had no difference ( P > 0. 05 ). Corneal epithelium defect, tears and photophobia were higher in 0.2g/L mitomycin C group (P<0. 05), which were no statistical difference between autologous corneal limbus stem cell transplantation and amniotic membrane transplantation (P>0. 05). Conjunctival congestion and subconjunctival hemorrhage in three groups had no statistical difference (P>0. 05).CONCLUSlON: Compared with other two operative methods, autologous corneal limbus stem cell transplantation for primary pterygium has the advantages of lower recurrence rate and less complications.

Objective:To analyze the expression of LETM2 in KYSE150 and ECA109 cell lines and its effect on the proliferation, migra-tion, and invasion of esophageal squamous cell carcinoma (ESCC). Methods:The expression level of the LETM2 protein in 90 paired hu-man ESCC tissues and matched adjacent normal tissues was determined through immunohistochemistry. The expression level of LETM2 in ESCC cell lines was detected by real-time PCR and Western blot. The expression levels of LETM2 in KYSE150 and ECA109 cell lines were knocked down using lentivirus. MTT assays were performed to examine the effect of LETM2 on the proliferation of ESCC cells. Colony formation assay was used to detect the colony formation ability. Flow cytometry was performed to analyze the cell cycle. The effect of LETM2 depletion on the migration and invasion of ESCC cells was determined by Transwell assay. Results:LETM2 expres-sion was frequently upregulated in the ESCC tissues than in the adjacent normal tissues. The suppressed exogenous expression of LETM2 led to the inhibition of cell proliferation and colony formation. However, cell migration and invasion were not affected. The re-sults on the cell cycle distribution revealed that LETM2 knockdown acts as a negative regulator of the cell cycle at the G1 to S phase transition. Conclusion:LETM2 acts as a tumor-driven gene in the development and progression of ESCC. This finding suggests that LETM2 can be used as an efficient prognosis biomarker and a potential therapeutic target for ESCC.

OBJECTIVETo investigate the correlation between matrix metalloproteinase 9 (MMP-9) expression and tumor invasion and metastasis as well, and to explore the potential application of controlled expression of target gene in tumor gene therapy.

METHODSOne self-contained tetracycline-regulated retroviral vector containing anti-sense cDNA of MMP-9 was constructed and transfected into a metastatic human melanoma cell line WM451 which expressed a high level of MMP-9. Techniques such as growth rate measurment, MTT assay, (3)H-thymidine incorporation, colony forming ability in soft agar, invasion assay in Boyden chamber, as well as zymography and Western blot were applied to analyze the expression of MMPs and behaviors of tumor cells in vitro before and after gene transfection. Tumorigenecity and spontaneous metastasis were tested in nude mice.

RESULTSIn the presence of exogenous tetracycline, the transfected antisense MMP-9 did not affect the endogenous level of MMP-9 in WM451 cells, and showed no significant changes in cell behaviors in comparison with that of the vector-transfected control cells. Nevertheless, withdrawal of tetracycline from the medium caused a significant down-regulation of expression and activity of MMP-9. The capacity of cell growth in vitro, colony forming ability in soft agar, invasion through Matrigel all were inhibited remarkably when compared with the controls. Spontaneous metastasis in nude mice was significantly inhibited.

CONCLUSIONSTransfection of anti-sense MMP-9 can down-regulate the invasion and metastasis of melanoma cells both in vitro and in vivo, further clarifying the important role of MMP-9 in tumor progression.
