查询词典 metastases

In the model of tumor cells metastases with cell line A673, 10〓 tumor cells can be detected after only one ampliation with outer primers, which means we can find 1 tumor cells in 10〓 normal PBMC, and enlarged again with inner primers, 10〓 tumor cells can be detected, which means we can find 1 tumor cell in 10〓 normal PBMC. In the simulative model of tumor cells metastases with RNA, 10〓 tumor cell can be detected that is to say we can find 1 tumor cell in about 10〓 normal PBMC. In all 15 samples of 11 patients, 2 patients'EWS/FLI1 expressions were negative, no evidence of metastases was found followed up by 8 months and 30 months respectively. Semi-quantitative study was used to detect the expression level of EWS/FLI1 mRNA in the other 9 positive patients, and metastases occurred in 6 high-level expression patients in 2-24 months after the operation, no evidence of metastases in the other 3 low-level expression patients up to now.

应用A673细胞系建立的肿瘤转移模型，单独应用外引物进行一次扩增，可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞；而在此基础上再次应用内引物扩增，则可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞；在用RNA模拟的肿瘤细胞转移模型中，两次扩增可以检测到10〓级肿瘤细胞，即可以从10〓个正常细胞中检测到1个肿瘤细胞。11例患者的15份标本中，2例没有检测到EWS/FLI1 mRNA的表达，分别随访8个月和30个月，没有发现临床转移的证据；对其余9例阳性表达的病例进行半定量的研究，6例EWS/FLI1 mRNA高表达的病例，分别在术后2-24个月发生转移，而3例EWS/FLI1 mRNA低表达的病例，则至今没有发现转移的证据。

Methods: 76 patients with colorectal cancer were collected in our department. They were divided into two groups, patients with metastases(MCRC,N=51) and patients after eradicative operation(non-metastasis group, NM,N=25).Serum markers of VEGF, OPN, CA19-9 and CEA were detected in all the included patients,and then to analyze the diagnostic value of the serum markers in detection of metastases.

测定76例结直肠癌患者（其中51例为转移性结直肠癌，25例为术后无转移者）血清中的VEGF、OPN和CA19-9及CEA水平，分析这些指标诊断结直肠癌转移的临床意义。

Objective To analyze the contrast enhancement appearances and patterns on dual phase helical CT scans in 21 cases with hepatic hypervascular metastases, and to discuss the value and pitfall of helical CT in diagnosing hepatic hypervascular metastases.

Results Most of the bone metastases are osteolytic (71%),and spine is the predilection site of bone metastases (53%).

X线、CT是诊断转移性骨肿瘤最基本的检查方法，掌握好转移性骨肿瘤的基本特性和转移特点有利于提高诊断水平，减少漏诊、误诊的发生。

Results 17 patients reported in the literature had primary bronchogenic carcinoma with metastases of phalanges of fingers as its first symptom. 7 patients' metastatic lesions located in their phalanges of left hands, 9 right hands and 1 both hands. The distribution of the quantity of the phalangeal metastases between two hands was almost equal. 3 patients' metastatic lesions were situated in proximal phalanges of fingers, and the rest in distal. 6 patients' ill fingers had had trauma history.

结果 在文献报道的以单纯指骨转移为首发症状的17例原发性肺癌的病人中，其转移病灶位于左手指骨者7例，右手指骨者9例，双手指骨者1例，指骨转移病灶的数量在两手之间的分布大致相等，除3例病人其转移病灶位于近节指骨外，其余病人的转移病灶均位于其末节指骨；有6例病人的患病手指既往曾有外伤史。

These prostate cancer bony metastases show an increased expression of the PTH receptor, and PTH promotes the growth and invasiveness of prostate cancer cells in bone. Hence, these blastic metastases appear to induce a "vicious cycle," in which PTH resorbs normal bone to support the growth of blastic bone.

这些转移到骨骼的摄护腺癌，其PTH受体的表现是增加的，且PTH促进骨骼中摄护腺癌细胞的生长与侵入性，因此，这些骨塑型的转移显然会造成一种恶性循环，PTH会分解正常的骨骼，以支撑骨塑骨骼的生长。

They were all right-handed.12 cases using conventional surgery were the control group(eight cases of glioma,3 cases of meningioma,1 case of brain metastases),eight cases of men,four cases of women;the average of 42 years old.
