摘要
研究幽门螺杆菌(helicobacter pylori)感染、突变型 p53基因表达与胃癌的关系,以及胃癌时 HP感染与突变型p53基因表达的关系。方法:用快速尿素酶试验和ELISA法检测HP和HP抗体,用免疫组化方法测定突变型p53蛋白。结果:胃癌和胃癌前病变组HP阳性率高于其它组(P<0.05),而胃癌组HP阳性率和胃癌前病变组无显著差异(P>0.05),胃癌组突变型 p53蛋白阳性率高于胃癌前病变组(P<0.05),胃癌中 HP阳性者突变型 p53蛋白阳性率高于 HP阴性者(P<0.05)。结论:胃癌的发生和HP感染、突变型p53基因表达有关,胃癌时HP感染与突变型p53基因表达也存在相关性。
Objective: To investigate the relation ship between helicobacter pylon(HP), mutant p53 expression in gastric cancer. Methods: Using immediate urease test and ELISA to detect HP, immuno histochemical staining to detect mutan p53 protein. Results: The positive rate of HP in gastric cancer and gasric precancerous conditions is higher than that of the other (P<0.05), but comparing gastric cancer with precancerous conditions, the two positive rates of HP have no significant difference (P>0.05). The positive rate of mutant p53 protein in gastric cancer is higher than in precancerous conditions (P<0.05) HP positive gastric cancer has a higher positive rate of mutan p53 protein than HP negative gastric cancer (p<0.05). Conclusion: HP inflammation and mutant p53 expression have a role in the development of gastric cancer. In gastric cancer HP inflammation has a connection with the expression of mutant p53 gene.
