目的:探讨纤溶酶原激活物抑制剂-1(PAI-1)基因启动子区的一个鸟嘌呤插入/缺失多态性(4G/5G)与胃癌侵袭和转移的关系。方法运用聚合酶链反应(PCR)和琼脂糖电泳对28例胃癌患者癌变胃组织与癌旁正常胃组织进行PAI-l基因4G/5G多态性检测和分析,并将两者进行比较。结果胃癌患者PAI-13种基因型在癌变胃组织和癌旁正常胃组织的表达差异无统计学意义(P>0.05),且在胃癌各期表达差异亦无统计学意义(P>0.05)。有淋巴结转移组的胃癌患者4G/4G基因型频率为52.6%,4G/5G基因型频率为47.4%,5G/5G基因型频率为0%;无淋巴结转移组分别为22.2%、55.6%和22.2%,两组基因型频率比较差异有统计学意义( P<0.05),其中4G/4G基因型相对于其他基因型差异有统计学意义(P<0.05)。结论 PAI-1基因多态性与胃癌的侵袭和TNM分期无关,而与胃癌淋巴结转移相关,4G/4G型可能是胃癌淋巴结转移的风险因素。
目的:探討纖溶酶原激活物抑製劑-1(PAI-1)基因啟動子區的一箇鳥嘌呤插入/缺失多態性(4G/5G)與胃癌侵襲和轉移的關繫。方法運用聚閤酶鏈反應(PCR)和瓊脂糖電泳對28例胃癌患者癌變胃組織與癌徬正常胃組織進行PAI-l基因4G/5G多態性檢測和分析,併將兩者進行比較。結果胃癌患者PAI-13種基因型在癌變胃組織和癌徬正常胃組織的錶達差異無統計學意義(P>0.05),且在胃癌各期錶達差異亦無統計學意義(P>0.05)。有淋巴結轉移組的胃癌患者4G/4G基因型頻率為52.6%,4G/5G基因型頻率為47.4%,5G/5G基因型頻率為0%;無淋巴結轉移組分彆為22.2%、55.6%和22.2%,兩組基因型頻率比較差異有統計學意義( P<0.05),其中4G/4G基因型相對于其他基因型差異有統計學意義(P<0.05)。結論 PAI-1基因多態性與胃癌的侵襲和TNM分期無關,而與胃癌淋巴結轉移相關,4G/4G型可能是胃癌淋巴結轉移的風險因素。

Objective To investigate the relationship between a guanine sub region of the insertion/deletion polymorphism (4G/5G) in the plasminogen activator inhibitor-1 (PAI-1) gene promoter and the invasion and metas-tasis of gastric cancer .Methods Polymerase chain reaction and agarose gel electrophoresis were performed to analyze the PAI-l gene 4G/5G polymorphism in cancer tissues and adjacent normal gastric tissues in 28 cases of gastric canc-er .Results Three genotypes of PAI-1 in gastric cancer tissues and adjacent normal gastric tissue were without signif-icant differences (P>0 .05) in patients with gastric cancer ,and the genotypes of PAI-1 were also without differences between patients at different TNM stages (P>0 .05) .The genotype frequency of 4G/4G in gastric cancer patients with lymph node metastasis was 52 .6% ,of 4G/5G was 47 .4% and of 5G/5G was 0 .0% ,which in patients without lymph node metastasis were 22 .2% ,55 .6% and 22 .2% .Genotype frequency of these two groups were with statisti-cal difference (P<0 .05) ,and genotype frequency of 4G/4G was significantly different with the other genotypes (P<0 .05) .Conclusion Polymorphism of PAI-1 gene might be not related to the invasion of gastric cancer and TNM sta-ges ,but closely related to lymph node metastasis of gastric carcinoma .Genotype of 4G/4G could be the risk factor in lymph node metastasis of gastric cancer .
