Results In RT-PCR analysis of the peripherial blood, 45%(18 out 40) of CRC patients, 10%(2 out 20) of CRP patients were positive for CEA mRNA, respectively. All 40 healthy individuals were negative for CEA mRNA expression. The detection of CEA mRNA was significantly correlated with TNM stage of CRC patients, while there were no significant relationship between the CEA mRNA expression and the malignant extent of cell differentiation.

结果 40例结肠癌患者外周血中CEA mRNA表达的阳性率为45.0%(18/40)，而健康对照组均为阴性，两者比较有显著性差异(P.01)；20例结肠息肉患者中CEA mRNA表达阳性率为10%(2/20)；CEA mRNA阳性表达率与肿瘤分期相关，而与肿瘤细胞分化程度并不相关。

Methods The CEA ScFv was radioiodinated (125I,131I) by iodogen solid labelling method.The uptake of radioactivity in tumor and normal tissues in 20 human rectocolonic tumor bearing nude mice was measured at 1,3,6 and 24 hour after peritoneal injection of 125 I-CEA ScFv and in 3 human rectocolonic tumor bearing nude mice imaging was carried out at 1,3,6 and 24 hour after peritoneal injection of 131 I-CEA ScFv.

采用Iodogen法制备125I-CEA ScFv和131I-CEA ScFv.20只荷人结直肠癌裸鼠，腹腔注射125I-CEA ScFv后1、3、6和24 h进行裸鼠的体内分布研究，对3只荷人结直肠癌裸鼠腹腔注射131I-CEA ScFv后1、3、6和24 h进行裸鼠的定位显像研究。

Methods Serum CEA and CA19-9 were detected by radio immunoassay in 38 patients of observation group with cholangiocarcinoma and carcinoma of ampulla before endoscopic retragrade cholangiopancreatography, took 5 ml bile to detecte CEA and CA 19-9 While ERCP, and took endoscopic biopsy for histopathological with the help of wise, recorded the feature of imaging. Bile CEA and CA19-9 were detected in 30 patients with unmalignant of contrast group in the same way.

观察组38例肝外胆管癌及壶腹癌患者在行ERCP检查前检测血清CEA及CA19-9，行ERCP检查时经造影导管抽取胆汁5ml用放免方法检测CEA及CA19-9，同时在导丝引导下自胆管咬取活检行病理检查，并记录影像学特征；同样，对照组30例非恶性病变患者在行ERCP检查时抽取5ml胆汁检测CEA及CA19-9。

"Despite evidence that the incidence of stroke increases with age, outcome from medical treatment is worse in the elderly, and early surgical outcome is reasonable in octogenarians, clinicians still have doubts about the overall benefit of CEA in these patients," the authors write.

尽管有证据显示中风会随著年龄增加老年人治疗效果差，再加上八十几岁的病人早期手术是合理的，但是临床医生仍然对八十岁以上的老人进行CEA的总体利益存有疑虑，作者认为，这些八十岁以上的病人CEA 之后的长期相对生存率好於对照组，不会因为年老对CEA造成危险，而且做了CEA可能活得更长久。
