不易表达的

PART FOUR EFFECTS OF MIL-4RA EXPRESSION VECTOR ON ASTHMATIC AIRWAY INFLAMMATION AND TH1/TH2 CELL DISFUNCTION THROUGH INTRAPERITONEAL ADMINISTRATION In the study of part three, we treated the mouse asthmatic model by intratracheal administration with mIL-4RA expression plasmid and observed obvious therapeutic effects. But intratracheal administration belongs to one of the insult therapies.

第四部分：腹腔注射mIL-4RA重组载体对哮喘小鼠气道炎症及Th失衡的干预作用前一部分研究中我们通过气道局部干预途径，即气管内直接滴注的方式，观察到mIL-4RA真核表达质粒对哮喘小鼠具有很好的治疗作用，但气管内滴注毕竟属有创性治疗，存在需要实验条件高，有较大的风险性，不易反复进行等缺点，这势必大大限制其在动物实验及进一步临床研究中的实际应用价值。

Thus, we try to express the functional domains separately by fusing with maltose binding protein.

由於大量可溶的全长P蛋白不易获得，因此我们尝试将各个domain分开表达。

Based on analysing the respective characteristics of regular PID controller in trational control theory and fuzzy logical controller in intelligent control theory, the idea and technique of expert system is introduced to develop a novel kind of hybrid intelligent controller. It can coordinate two kinds of control algorithms and tune the control parameters on-line for different working zones of the controlled process.(3) The hybrid knowledge expression model, which combines discrete state space model, fuzzy relational model and rule base model, is proposed based on analysing the characteristics of all kinds of knowledge expression models. The knowledge of the controlled process in different aspects can be expressed resonably by it. Based on the model mentioned above, the related optimization strategy for complex system is developed.

本文的主要贡献体现在：（1）以炼油厂的催化裂化装置和钢铁联合企业的大型焦炉装置两个典型的复杂工业过程为例，分析了工业大系统的许多不易控制的特性，并归纳了其中的几个典型特征；（2）针对经典控制理论中的常规PID调节器和智能控制技术中的模糊逻辑控制器各自的特点，通过引入专家系统的思想和方法，开发了一类混合式专家控制器，它同时具备在线协调两种不同控制规律和自动学习控制规则的能力；（3）通过分析各种知识表达模型的特点，提出了一类包括离散状态空间模型、模糊关系模型和规则基模型在内的混合知识表达模型，它能对过程知识在各个不同侧面给予合理的描述。

This study has achieved the following purposes,observed effects of different levels of noise exposure on the auditory function and the hearing organ of guinea pigs,explored optimal noise exposure profiles for research of NIHL susceptibility,established NIHL susceptibility model,148 differentially expressed genes of cochlea between NIHL susceptible and unsusceptible guinea pigs were screened by using suppression subtractive hybridization.The results of bioinformatics analysis showed that there are 34 sequences whose homology were larger than 80% and match sequence larger than 100 bp.

本研究观察了不同噪声暴露量对豚鼠听觉功能和听觉器官结构的影响，探讨了NIHL易感性研究的最佳噪声暴露方案，建立了NIHL易感豚鼠模型，利用抑制性消减杂交技术筛选NIHL易感与不易感豚鼠耳蜗的差异表达基因片段148条，生物信息学结果显示同源性大于80%且匹配碱基大于100 bp的片段共34条。
