Vibrio cholerae adherence to and colonization in the small intestine are essential step in the pathogenesis of cholera. At least one type of pili, known as TcpA, is required for the colonization process. This paper reports the electron microscopic evidence showing that V. cholerae 01 and 0139 serogroups can express at least 4 types of pili when incubated at 28℃ on AKI agar or CFA (pH6.8). Among the four types, three can be expressed by classical and El Tor strains of Vibrio cholerae 01: TcpA pili are peritrichous,being 7-8nm in diameter, 5-10μm in length, and form bundles of parallel undulating filaments of 0.5-0.8 μm wide and 10-15μm long; Type B are 3-4nm in diameter, up to 2μm long, and of wavy morphology; Type C are 7-8nm wide and 0.5-0.8μm long.

本文通过电子显微镜对01群霍乱弧菌古典生物型和El Tor生物型以及0139群霍乱弧菌研究发现，在培养基AKI和CFA(pH6.8)28℃培养条件下，01群EVC和CVC均可产生TcpA，B型和C型菌毛；0139群霍乱弧菌可产生TcpA和B型菌毛，与01群一致。

Object: The project is on the basis of chronic alcoholic myopathy model of rat, to dynamically observe the change of NF-κB and MMP-2, MMP-9 in muscle cell, observe the function in the mechanism of alcohol myopathy, move forward a single step to explain the pathogenesy of this disease from gene and protein leve. We also provide a helpful platform for other metabolic myopathy. Methods:(1) 80 health, male, Sprague-Dawley rats(weight 180~200g), were chosen to sep up the CAM rat myopathy model ,to observe the rat bodyweight, the change of praxiology and the patho-change of muscle tissue.

目的：本实验旨在建立大鼠慢性酒精中毒性肌病模型的基础上，动态观察NF-κB及MMP-2、MMP-9在酒精中毒性肌病发展中的表达、变化情况，探讨其在慢性酒精中毒性肌病发病过程中的作用，从基因和蛋白水平进一步阐述该病发病机制，为慢性酒精中毒性肌病的临床防治提供理论依据，同时对于其他代谢性肌病的研究也提供一个平台。

As a key step of the synthesis, the Friedel-crafts acylation was researched. And the optimal operation variables were determined through orthogonal experiment: when 0.lmol acetanilide, 0.26mol aluminum chloride, 0.12mol propionyl chloride and 200ml carbon disulfide are introduced, and the reaction time is 5 hour, the yield can be up to 57.3%. The solid super acid catalyst was preliminary studied. Four solid super acid catalysts were prepared to take the place of aluminum chloride, and it was indicated that AlCl3 acidic resin can better catalyze the Friedel-Crafts reaction of acetanilide.

对合成路线中的Friedel-Crafts酰基化反应进行了研究，运用正交实验设计确定了最佳工艺条件：当乙酰苯胺用量为0.1mol时，AlCl_3用量为0.26mol、丙酰氯用量为0.12mol、溶剂用量为200ml、反应时间为5h，产率可达到57.3％；对于固体超强酸催化剂进行了初步研究，合成了四种催化剂，其中负载AlCl_3强酸性树脂对于乙酰苯胺的Friedel-Crafts酰基化具有一定的催化活性。
