Polymarase Chain Reaction may be the better method of detecting M.tuberculosis than other methods and lead us to carry out a series of research on this problem. This thesis is composed of five parts:(1)systematic evaluation for the first time of the ability of five defferent PCR methods to detect M. tuberculosis;(2) using the endonuclease and southern blot by a radioactive and a nonradioactive labeled probe, to confirm the specificity of the PCR products and to analyse the sensitivity of detection by southern blot method using digoxigenin-labeled probe;(3) evaluation of acid-fast staining, bacterial culture and PCR for the detection of M. tuberculosis in sputum, pleural and peritoneal effusion samples;(4) The feasibility of PCR for detection of M tuberculosis on formalin-fixed paraffin embedded tissues;(5) 26 cases of sarcoidosis were retrospectively studiedwith PCR for M. tuberculosis and nontuberculosis Mycobacterium and the problems on histopatholoical diagnosis of sarcoidosis are discussed.

论文共分为五个部分，(1)首次系统地比较了五种不同引物序列的PCR检测结核杆菌方法的特异性和敏感性等情况；(2)利用限制性内切酶酶切分析和同位素及非同位素标记DNA探针进行Southern杂交的办法，分析PCR产物的序列与原设计是否相符及杂交检测PCR产物对提高检测结核杆菌敏感性的情况；(3)并对PCR用于快速检测临床标本中的结核杆菌进行了初步评价；(4)探讨了PCR用于检测石蜡包埋组织中结核杆菌的作用；(5)并利用PCR检测结核杆菌和非结核分枝杆菌的方法对26例原病理诊断为结节病的病例进行了PCR检测及组织病理学诊断的探讨。

The content of the parental rights and minor children's rights of privacy has all aimed to the private life of minor children's study and entertainment, which has created the condition of the conflicts between the two parties. Neither the law of our country has detailed stipulated for the content of parental rights, nor stipulated restrictedly to minor children's rights of privacy. The legitimate right is the basis to realize the right and ensure the right is legal. Because of the unperfected law, both two parties haven't got a clear confine in using their rights. So it also becomes one important reason of the conflict. In the past, parents use their guardianship as the hegemony which including some long-history autocratic tradition. It is the cultural factor of disregarding and excluding the individual privacy. With the development of democracy and legal system, citizen including minor children have realized their rights to privacy which has also become one reason to raise the right conflict.

因父母行使亲权与未成年隐私权的内容均指向了未成年人的学习娱乐等私生活，为两者发生冲突创造了条件；而我国法律既未对父母行使亲权的内容作具体详实的规定，也未对未成年人的隐私权作限制性规定，权利的法定化是为权利的实现和保障奠定法律基础和合法性依据的，法律本身的不完备、不完善使得权利主体行使权利的界限不明确，也是造成权利冲突的重要原因；古代以家长权为支配权的亲子法，包括中国古代社会存在的源远流长的专制传统，是对个人隐私的漠视和排斥的文化因素；随着民主法制的发展，公民包括未成年人权利意识的发展，也是权利冲突现象增多的一个直接导因。

Subsequently, the optimized technology was successfully scaled up to 〓 pilot bioreactor scale by using the parameter simulation method. The scale-down strategy was applied to the 100〓 fermentation tank to ascertain that the determining factor which affects metabolic flux distribution reasonably had changed to the dissolved oxygen control. After resolution of the DO limitation, the optimized technology inhibited the shift on 100〓 production scale correspondingly, notable commercial returns was gained as a result.

随后基于过程参数拟合的方法成功地将抑制代谢流迁移的新工艺放大到12〓规模，并通过规模缩小证实了100 〓生产规模的发酵过程中限制代谢流合理分配的限制性因素已经发生了变化，此时DO的控制成为优化的前提，通过改善供氧条件之后优化的工艺在生产规模也成功的克服了代谢流的迁移，取得了显著的经济效益。

Restrictive changes of TCR Vp repertoire and clonal expanded T cells could be found in peripheral blood T cells from patients with T-ALL. However, the clonal expanded T cells' property (clonal expansion leukemic cells or leukemia antigen-specific expansion T cells) should be further characterized. It may play a certain role on detection of minimal residual disease and design of anti-leukemia idiotypic vaccine. The dominant utilization of TCR VjJ repertoire could be found in peripheral blood T cells from patients with B-ALL, meanwhile clonal expansive T cells were existed. It may be a feature of the host immune response for leukemia-associated antigen. The clonal expansive tendency of T cells in V021 and VP23 subfamilies was rather obvious, which may be correlated with certain malignant B-cell clone. The CDR3 sequences of monoclonal expansive T cell in T cell strains were different, which was the base of developing DNA vaccine.

T-ALL患者外周血T细胞的TCR Vβ谱系出现限制性改变，均可检测到克隆性增殖T细胞，尚需进一步鉴定其性质(肿瘤性或抗原特异性增殖)，对于研究微小残留病变检测和设计抗白血病独特型疫苗均有一定的意义。B-ALL病人外周血T细胞的TCR Vβ谱系呈现优势利用的特点，并存在克隆性增殖的T细胞，这可能是机体对白血病相关抗原产生的特异性免疫反应；Vβ21和Vβ23亚家族T细胞发生克隆增殖改变的趋向性比较明显，可能与B-ALL相关抗原刺激有关。T细胞株中检测到的肿瘤克隆其CDR3序列具有高度的特异性，是构建DNA疫苗的基础。

But science neither simply opposes against metaphysics nor simply merges with it, their relationship is complex: they are interdependent, interpenetrated, mutually conditional, mutually conductive, and work in coordination, at the same time, they are mutually exclusive, and hold each other back. Besides these harmful influence and positive contribution, there're more other interactions in varied dimensions, which are determined by specific scientific theory and specific metaphysical one.

本文认为，形而上学是科学之所以可能的一个主体条件，同时又是科学发展的一个限制性条件，但是，科学和形而上学之间既不是简单的融合也不是简单的对立，它们的关系具有复杂性：科学和形而上学既相互渗透又互相反对，既相互制约又相互诱导，其作用方式和作用效果又是多重的、有差别的、复杂的，这既取决于具体的科学理论又取决于具体的形而上学学说。

Its requirements are as follows: in principle, a person with capacity for rights could be identified as a beneficiary, and the beneficiary must enjoy certain beneficiary right, except as otherwise prohibited or limited by law. the trustee, in breach of trust, disposes of the trust property, but it does not require the detriment to the trust property and the trustee's fault. when the trustee disposes of the trust property to a third party, the Chinese trust law requires that the third party knows of the trustee's breach. In contrast, the logic which the rule of a bona fide purchaser in common law and the mechanism of trust publicity in civil law demonstrate seems to be more reasonable.

信托受益人撤销权的成立需具备以下要件：其一，原则上，具有民事权利能力的人都可以成为受益人，但法律有禁止性或限制性规定的除外，且受益人须享有确定的受益权；其二，受托人违反信托目的处分信托财产，但不以对信托财产造成了损失为必要，也不要求受托人主观上具有过错；其三，当受托人将信托财产处分给第三人时，《中华人民共和国信托法》要求该第三人明知受托人违反信托目的处分信托财产，相比之下，英美信托法中的&善意购买人&规则和大陆法系信托法中的信托公示制度所内含的逻辑似乎更为合理。
