XPF、p53蛋白在胃癌组织中的表达及与幽门螺杆菌 L型感染的关系
Relationship between Helicobacter pylori L-form infection and expression of XPF and p53 in gastric carcinoma
摘要
Abstract
Purpose To investigate the relationship between Helicobacter pylori L-form ( Hp-L) infection and expression of XPF and p53 in gastric carcinoma. Methods XPF, p53 and Hp-L were examined in 239 cases of gastric carcinoma and healthy individuals by means of Giemsa stain and immunohistochemical staining with ABC method. Results XPF and p53 expression in gastric carcinoma was significantly higher than that of the surrounding tissue (P<0. 01). There were positive correlation between the expression of XPF and p53 (r=0. 196, P<0. 01). The expression of XPF was related to the Laurén classification (P<0. 05). The expression of p53 was associated to the depth of invasion (P<0. 05). (2) 175 (73. 22%) cases were Hp-L positive by both Giemsa and immunohisto-chemical staining. Hp-L expression in gastric carcinoma were significantly higher than that of the surrounding tissue (P<0. 01). (3) In the Hp-L positive group, XPF and p53 were significantly higher than in that of the Hp-L negative group (P<0. 01). Positive corre-lation existed between positive Hp-L staining and the expression of XPF and p53 (r=0. 32, r=0. 296, P<0. 01). (4) Univariate a-nalysis showed that depth of invasion, distant metastasis, TNM stage, XPF and p53 were related to the prognosis of gastric carcinoma ( P<0. 05). Multivariate Cox model analysis showed that XPF was an independent prognostic factor for the patients (P<0. 05). The pa-tients with positive expression of XPF had a shorter survival time. When combined with the depth of invasion and distant metastasis, the correction risk increased by 3. 791 times. Conclusion XPF, p53 and Hp-L may play very important roles in the development of gastric carcinoma. The high expression of XPF implies poorer prognosis. Hp-L infection may be related to the up-regulated expression of XPF and p53.关键词
