RESUMO

Objective@#To investigate the role of lncRNAs in the invasion and metastasis of salivary adenoid cystic carcinoma (SACC) cells.@*Methods@#With SACC-LM as the experimental group and SACC83 as the control group, lncRNA chips were used to screen the differentially expressed lncRNAs. The differentially expressed lncRNAs were further verified by real-time quantitative RT-PCR (qRT-PCR). The invasion and migration abilities of the adenoid cystic carcinoma cell lines before and after transfection with lncRNA siRNAs were detected by invasion and migration experiments. The clinicopathological features and prognosis of patients with different expression of lncRNAs and SACC were analyzed.@*Results@#The microarray showed that ADAMTS9-AS2 was highly expressed in the SACC-LM cells. Real-time quantitative RT-PCR further confirmed that ADAMTS9-AS2 was significantly upregulated in the SACC-LM cells. Invasion and migration experiments showed that the invasion and migration were significantly reduced after the expression level of ADAMTS9-AS2 was downregulated (P < 0.001). Analysis of the clinicopathological data showed that ADAMTS9-AS2 was highly expressed in SACC. High expression of ADAMTS9-AS2 was associated with poor prognosis and a high tumor metastasis rate in SACC patients.@*Conclusion @#High expression of ADAMTS9-AS2 promotes the migration and invasion of SACC cells. ADAMTS9-AS2 is upregulated in the SACC tissues and is related to a high metastasis rate and poor prognosis.

RESUMO

Objective@#To evaluate the effect of palatal free gingiva in anterior maxillary defect restoration after epulis resection. @*Methods@# 22 cases were included in this study. Palatal free gingival flap was prepared to restore anterior maxillary defect after epulis resection. Clinical effect was evaluated according to gingival margin, gingival papilla index and modified sulcus bleeding index. @*Results @#Satisfactory clinical effect was achieved in all 22 cases, with adequate height, thickness, fullness and texture. @*Conclusin @#Palatal free gingival flap was clinically effective in anterior maxillary defect treatment after epulis resection, with satisfactory aesthetic clinical effect.
