光动力疗学法下调人口腔癌的促侵袭因子
背景与目的头颈部鳞状细胞癌的重要特点是高侵袭性和转移性.以往研究已确定了促侵袭因子基质金属蛋白酶(matrix metalloproteinases,MMPs)、血管内皮生长因子(vascular endothelial growth factors,VEGF)及尿激酶溶酶原激活剂(urokinase plasminogen activators,uPA)参与该过程.

氧化应激在口腔癌发生中的作用
氧化应激能导致细胞内DNA碱基改变、链断裂、抑癌基因失活、原癌基因的表达增高,因此其与包括口腔癌在内的许多癌变的发生有关.本文主要从口腔癌患者机体氧化还原状态的改变;吸烟、饮酒、嚼槟榔与口腔癌及氧化应激的关系;维生素、微量元素与氧化应激的关系;放化疗对口腔癌患者氧化还原状态的影响等方面对氧化应激在口腔癌发生中所起的作用作一综述.

PURPOSE: The aim of this study was to investigate symptoms of depression and anxiety in the patients with oral squamous cell carcinoma (OSCC). METHODS: 76 patients with oral squamous cell carcinoma participated in this program. All patients were rated with the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS). The mean scores of SAS and SDS were compared to those scores of the Norm of Chinese people. In addition, the different treatment results of the patients with different levels of anxiety and depression were studied. Further, the number of patients of SAS, SDS with more than 50 score were compared between primary cancer patients and recurrent cancer patients. RESULTS: The scores of SAS, SDS and the number of patients with more than 50 score in the patients group were obviously higher than those in Chinese Norm (P<0.01).The levels of anxiety and depression in 32 patients with recurrent cancer were more severe than those of 44 patients with primary cancer. The patients with anxiety and/or depression showed poor prognosis. CONCLUSION: Anxiety and depression are common symptoms in patients with OSCC and have negative effects on the prognosis, thus the psychological intervention for the patients must be carried out.
