There were only 5 cases negative for SYT-SSX genomic by seminested PCR, which were positive for SYT-SSX mRNA by RT-PCR. Three cases of synovial sarcoma negative for SYT-SSX mRNA were also negative for SYT-SSX genomic DNA. One case of synovial sarcoma was positive for SYT-SSX1 genomic DNA by seminested PCR, which can not be distinguished for SYT-SSX fusion type by RT-PCR.

In this paper,the existence of multiple positive solutions for a class of fourth-order p-Laplacian operator singular boundary value problems is discussed by using the fixed point index,and some sufficient conditions are given such that the problem has at least two positive solutions.

This result can best be viewed as a quantum black hole version of the third law of thermodynamics. As a result of this area spectrum, the spectrum of M is discrete, bounded below, and can be made positive. Prom the physical point of view, the semiboundedness and positivity of the spectrum are very satisfying results: The semi-boundedness of the spectrum implies that one cannot extract an infinite amount of energy from the system, whereas the positivity of the spectrum is in agreement with the well-known positive-energy theorems of general relativity.

同时根据EMDA黑洞动力学，存在与面积谱对应的大于零且有下界的质量离散谱，从物理上来看，质量谱的半有界性意味着不可能从系统吸取无限的能量，而正定性则与广义相对论中的正能定理一致，也就说稳态轴对称EMDA时空的ADM能量总是大于零。

Thirdly, we will concentrate on the multiplicity of the positive and minimal sign-changing solutions of the following quasilinear equations with Hardy-Sobolev critical exponent in bounded domain By Lusternik-Schnirelmann category theory, we showthe relation the number of positive solutions with the topology of the domain.

再次研究有界区域上具有Hardy-Sobolev临界指数的拟线性方程的正解与极小变号解的多重性，运用Lusternik-Schnirelmann理论，给出方程正解与区域的拓扑性质的相关性。

Shanghai Stock Index K line graph shows that the recent average stock in the short to medium term as well as the rail line near Brindisi in a stalemate, if follow-up to further positive measures introduced on short-term stock index is expected to form a positive stimulus, but I believe that stock is expected to run high relatively limited.

上海证券交易所指数K线图显示，近期的平均股价在短期至中期，以及在僵持布林迪西铁路线附近，如果后续短期股票指数采取了进一步的积极措施，预计将形成积极的刺激作用，但我相信，股票预期高涨相对有限。

Was presented in 12 cases (24%) by bacterial isolation. By in-situ hybridization, PCV2 signals were chiefly distributed in interstitial and necrotic lesions, and the positive signals could be found in macrophages-like cells and necrotic debris. PRRSV signals were mainly located at interstitial lesions and alveolar wall, and the positive signals could be found in macrophages-like cells and epithelial cells of alveoli. Swine influenza virus could be found in interstitial and necrotizing lesions, and the signals could be found in macrophages-like cells, and epithelial cells of terminal bronchiole and alveoli.

另运用原位杂交法对PCV2、PRRSV及猪流行性感冒病毒进行检测，结果发现PCV2主要分布於PNP的间质及坏死病灶区，并能於肺泡及终末细支气管上皮细胞、巨噬细胞与坏死细胞碎片皆可见有病毒核酸；PRRSV则多分布於间质病灶区及肺泡壁处，能於巨噬细胞与肺泡上皮细胞见到病毒核酸；SIV则存在於间质及坏死病灶区，且能於肺泡及终末细支气管上皮细胞与巨噬细胞见有病毒核酸。
