Immunohistochemical Study of Colorectal Polyps with Antibodies against CEA,CA19-9, CA125, CA15-3 (DF3), PCNA and p53

Abstract: We analyzed the expression of CEA, CA19-9, CA125, CA15-3 (DF3), PCNA and p53 immunohistochemically in 14 tissue specimens of mucosal cancers in adenoma, seven tubulovillous adenoma specimens, and 16 tubular adenoma specimens. The rates of positive staining for mucosal cancer in adenoma, tubulovillous adenoma and tubular adenoma specimens, respectively, were: for CEA: 100%, 85.7% and 75%; for CA19-9: 71.4%, 71.4% and 56.2%; for CA125:0%, 0% and 0%;for CA15-3 (DF3): 64.3 %, 0% and 0 %; for PCNA: 100%, 88.9% and 56.2%; and for p53: 35.7%, 0% and 0% . The results suggest that the expressions of CEA, CA19-9, CA15-3 (DF3), PCNA and p53 are related to colorectal tumorigenesis. None of the specimens studied showed staining for CA125, suggesting that CA125 is not involved in the early stages of colorectal carcinogenesis. There was no significant difference in the rates of positive staining for CEA and CA19-9 among mucosal cancer in adenoma, tubular adenoma and tubulovillous adenoma specimens. However, the rates of positive staining for PCNA and p53 were significantly higher in mucosal cancer in adenoma specimens than for tubular adenoma specimens (p<0.05), and the rate of CA15-3 (DF3) positive staining was significantly higher for mucosal cancer in adenoma than for tubulovillous adenoma (p<0.01) and tubular adenoma (p< 0.001) specimens. Therefore, the CA15-3 (DF3) antigen is an immunohistochemical marker for colorectal carcinomas. The present results suggest that CA15-3 (DF3), PCNA and p53 play important roles in the genesis of colorectal adenomas.     

大肠癌手术前后血清CA199和CEA水平变化临床价值的研究

目的:研究大肠癌患者手术前后(包括根治术及姑息手术)血清CA199和CEA水平的变化.并探讨其应用价值。方法:应用全自动化学发光免疫分析法,分别测定临床确诊的50例大肠癌患者(术前和手术30 d后)及50例正常成人血清CA199与CEA含量变化。结果:50例大肠癌患者手术前后血清CA199和CEA检测显示,术前血清CA199和CEA均高于对照组(P<0.01),术后血清CEA较CA199下降快,而且大肠癌患者术前血清CA199和CEA含量较根治术30 d后有明显增加,差异有统计学意义(P<0.05)。而姑息性切除手术前后血清CA199和CEA含量变化不大(P>0.05),差异无统计学意义。结论:大肠癌患者术前血青CA199和CEA含量显著增高.而根治术后血清CA199和CEA均有较明显下降。因此,术后定期联合监测血清CA199和CEA有利于临床观察大肠癌患者病情变化,评价手术效果,预测首程化疗疗效,为判断预后、及早发现术后复发病人提供依据。

Association analysis of CA repeat polymorphism of the endothelial nitric oxide synthase gene with essential hypertension in Japanese

The nitric oxide synthase (NOS) gene is thought to be associated with essential hypertension (EH), because NO is implicated in endothelium-mediated vasodilation. We investigated the possible association between the alleles of simple tandem repeat DNA polymorphism of the endothelial constitutive NOS (cNOS) gene and EH in Japanese subjects. In all, 100 patients with EH and 123 subjects with normal blood pressure were studied. Polymerase chain reaction was used to amplify the CA repeat site in the endothelial cNOS gene and alleles based on the CA repeat number were determined. The allele frequencies in the hypertensive group and normotensive group were then compared. Twenty-three alleles were identified in this study of Japanese subjects. The overall distributions of allele frequencies in the two groups were not significantly different. However, comparing the allele frequencies in the EH group without left ventricular hypertrophy (LVH) and the normotensive group, the overall distributions were significantly different (p = 0.019). The 33-repeat allele was found more frequently in the EH group without LVH than in the normotensive group (p = 0.000047, Odds ratio = 3.71). In conclusion, the 33-repeat allele of the endothelial cNOS gene is associated with EH without LVH, and may be a genetic marker of EH in Japanese subjects.
