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。

objective to evaluate the value of infrared thermography in the diagnosis of injuries in such soft tissues as neck,shoulder,waist,leg,elbow and wrist.methods infrared thermograph (type wp-95) was used to do general physical check up for 221 young soldiers with a regular military training history ranging from 1 to 5 years,whose infrared thermograms were then compared with those of 100 new recruits without any military training experience.results there were abnormal thermograms on 180 (81.45%) of the 221 cases and 6 (6%) of the 100 new recruits （p.05.all of the 186 cases with abnormal thermograms were x-rayed with only 28 cases(i.e.15.05%) abnormal.there was a distinct difference between the two methods of physical check-up (p.05).conclusion infrared thermography manifests distinctive abnormal thermograms of soft tissue injuries suffered from military training,providing definite diagnostic message for clinic.to utilize infrared thermography correctly is of vital importance in ensuring the health of servicemen.

We want to move up ticklish Stone, the facilities of the moment will be greater than the force of gravity produced by a rock moment, we all know that the moment arm of force multiplied by the force equal to the size of the arm of force as an arm of force in the greater 2 , Finger pressure, the more gravity than, stone ticklish ticklish point of this very long arm of force, so we used a very small force so that the stones will be able to move up.

我们要想让怕痒石动起来，所施的力的力矩就要大于石头重力所产生的力矩，我们都知道力矩等于力臂乘以力的大小，当力臂2越大于力臂1时，手指压力也就越小于重力，怕痒石怕痒的这个点的力臂非常长，所以我们用很小的力就能使石头动起来。

Up till now, the main pump types used in CPB are roller pump and centrifugal pump, but these two kinds of pump both have their own disadvantages. When roller pump is used, the blood cells will be destroyed severely and when the pipeline is kinked, air will be transported into body or the conduit will be broken. The function of centrifugal pump is better than that of roller pump, but now, this kind of pumps are all designed for adults, and when the flow rate is low, the function of protecting the blood is not significant.

目前，滚轴泵和离心泵是心肺转流中的常用泵型，但是滚轴泵对血液有形成分的破坏较严重，而且有引起泵管的崩脱和大量气体泵入体内的危险性；离心泵虽然在性能上优于滚轴泵，但目前的离心泵大都是为成人设计的，而且在低流量时在血液破坏方面的优点不明显，此外它们还有一个共同的缺点就是预充量均大，因此两者都不适合在幼婴儿体外循环中应用。
