The mice inoculated with Coxiella burnetii intrana- sally developed interstitial pneumonia,while the primary pathological changes of mice inoculated intraperitoneally are granulomas in spleen and liver.2.The pathological changes became more severe followed the dosage increasing.3.Coxiella burnetii can be detected in spleen and liver at day 2 after inoculation.the lesion became more and more serious from day 2 to day 12.The characteristic changes were observed at day 7,and recovered at day 14. 4.The reticuloendothelial system are main target of Coxiella burnetii.The pathogen was detected in cytoplasm of monocyte -macrophages of spleen, liver, lung, and endothelioid cells of blood vessel. 5. Coxiella burnetii can be found in macrophages lysosomes by electron microscopy. Most of them are round or rod, and polymorphic shape can also be observed in different size.
结果:1、通过不同感染途径的实验证实,滴鼻感染的小鼠主要表现为间质性肺炎,而腹腔注射感染小鼠则以脾脏、肝脏肉芽肿为主要病变。2、通过不同剂量的感染实验发现,随着感染Q热立克次体剂量的加大,动物病变愈加严重。3、通过感染后不同时间的动态病理学观察发现,在腹腔注射后第2d的脾和肝脏即可发现病原体,主要脏器的病理变化从第2d到第12d逐渐加重,第7d动物的病变最典型,至感染后14d动物的受损器官已开始出现修复性变化。4、 Q热立克次体主要侵害机体的网状内皮系统,在感染小鼠的肝、脾、肺和外周血管单核巨噬细胞以及血管内皮细胞胞浆中查见病原体。5、透射电镜观察可见Q热立克次体主要位于巨噬细胞吞噬溶酶体内,呈多形性,多见圆形和杆状,大小不一。

Based on the deterioration mechanism of corrosive medium, a lot of polymer such as ternary-polymer, adding-felt addition, hydrophobe and polypropylene fiber were added to enhance the performance of anti-corrosion, anti-penetration, conglutination and anti-cracking of original cementious material. The microstrure of cementious material was changed from the simplex hydration product of cement to the superposition structure of the hydrolysate of polymer and the hydration product of cement. A lot of the corrosive ions were prevented from the interior of concrete by this stable structure. The results of tryout indicated that the mending material has the good effect at the corrosion form of corrosive medium.

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.
许多的载体,病毒载体和非病毒载体以前已广泛应用,病毒载体主要包括腺病毒,逆转录病毒,腺相关病毒等;但病毒载体在安全性方面存在潜在的危险;免疫原性比较强,注射到机体后很快会被机体的免疫系统排斥,当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应;非病毒载体目前常用的有脂质体及多聚阳离子聚合物;但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性,转染效率较低且易被网状内皮系统吞噬,基因表达时间短;因此研制新型的非病毒载体已成为研究的热点,纳米颗粒具有小尺寸效应,表面效应,随着颗粒直径变小,比表面积将会显著增大,故具有很高的化学活性,因而纳米成为了最有应用前景的非病毒载体。

Transcription, and analyzes Wangs inheritance, reproduction and development of Chinese ethical folk music. She also makes transverse comparisons between the musical forms of piano works by composers of both China and abroad, and illustrates that Wang uses for inference but not copies the western musical forms, that he attaches importance but not stickles to the framework of traditional Chinese music, and also that he demonstrates a characteristic of not sticking to one pattern. She makes contrastive comparisons as well of the melodies and harmonies of piano works by composers of both China and abroad, and indicates that in inquiries into the folk style of counterpoint, Wang is flexible and creative in harmonies by inheriting the character of a clear melody and the method of multi-voice in Chinese traditional music and also by absorbing the character of emphasizing the layers of texture in western piano music.

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.
