Many studies have reported that Klebsiella pneumoniae is associated with ankylosing spondylitis but the mechanism of pathogenesis is remained unclear. The endoplasmic reticulum stress would be induced upon exposure of decapsulated KP in HLA-B27 expression B lymphoblast CA46 cells and non-HLA-B27 expression U937 monocytes. Our previous studies demonstrated that decapsulated KP could up-regulate BiP/Grp78 and calreticulin expressions in a dose- and time-dependent manner. We screen more than 60 kinds of traditional herbs and bioactivity agents and we found that berberine,taurine,extracts of Andrographis paniculata Nees.

许多研究指出克雷伯氏肺炎杆菌和僵直性脊椎炎有相当的关系，但是致病机制仍然不是很清楚，因此我们使用去荚膜克雷伯氏肺炎菌来诱发表现HLA-B27的CA46 B淋巴球母细胞、不含HLA-B27的U937单核球细胞可以产生内质网压力，我们先前的实验指出，随著剂量增加，去荚膜克雷伯菌能够过度调控内质网压力指标蛋白质BiP和Calreticulin表现增加。

The group disposed by Acetylspiramycin doesn"t show parallel results; The strip gray scale of exotoxin A decreased gradually with the increasing dosages of Azithromycin and Roxithromycin, which doesn"t show in group disposed by Acetylspiramycin and group PAO-JP2; The strip gray scale of lasR, detected by RT-PCR, decreased gradually with the increasing dosages of Azithromycin, which doesnt show in group PAO-JP2.Conclusions: There were obvious differences between PAO1 and PAO-JP2 in biology characteristics in vitro.

本研究发现大环内酯类药物在生物被膜培养过程中分别处理PAO1、PAO-JP2，结果提示大环内酯类药物(14、15元环)通过对QS系统的影响可有效抑制铜绿假单胞菌生物被膜的形成；通过QS系统有效抑制铜绿假单胞菌的毒力因子的产生，16元环的大环内酯类药物乙酰螺旋霉未见上述结论；lasR基因的反转录结果提示阿奇霉素可在转录水平抑制QS系统发挥其作用。

The sewage flows from pool to plant, passing through retention reservoir to adjust PH value, into removing ammonia with temperature increasing to 20℃,into UASB reactor with temperature increasingto 35℃ to remove off COD and ammonia under the function of anaerobia, then into SBR reactor to remove BOD under the function of aerobia. When the biochemical disposal is completed, the processed sewage will come into the UF system to remove adsorbed solid, organic matter, bacteria, and pathogens in waterand finally come into the RO system to remove off dissolvable salinity, colloid, organic matter, and microbe in water.

垃圾渗滤液经储存池进入污水处理厂，经调节池调整PH值，经1#加热器升温到20℃进入氨吹脱塔脱氨氮，再经2#加热器升温到35℃进人UASB生物反应器，在厌氧菌的作用下降解COD和脱氮，再进入SBR生物反应器，在好氧菌的作用下降解BOD，完成生化前处理后转入UF超滤中空纤维膜系统进行分离处理吸附固体、有机物、细菌、病原体等；最后经高压泵送入进口的RO返渗透中空纤维膜系统中，进行分离处理可溶解盐分、胶体、有机物、微生物等。

The SEM graphs showed that PAO1 only can form scattered cenobium in iron-depletion environment.

PAO-JP2正常情况下形成的被膜结构就很不典型，菌团小且稀疏、散在的细菌多；缺铁时仅可观察到少量单个菌体黏附在硅胶膜表面。

To validate an investigation method for the epidemiology of Clostridium perfringens in chicken,genetic diversities of 34 strains of C.perfringens type A isolated from healthy chicken of 10 diffe-rent integrated chicken farms in Sichuan Province were analyzed by repetitive extragenic palindromic PCR and amplified fragment length polymorphism methods.

为探讨鸡产气荚膜梭菌流行现状的调查方法，采用REP-PCR(repetitive extragenic palindromic PCR)技术对四川省10个规模化鸡场分离得到的34株A型产气荚膜梭菌进行了遗传多样性分析，并与AFLP（amplified fragment length polymorphism）方法进行了分型比较。

METHODS: Constructing the CAM model by exposing CAM on the shell subpoint between 2 vitelline veins and generating an air chamber after 5 days of incubated with aseptic incubator at 37℃.

将鸡胚消毒后，置于37℃无菌恒温箱中孵育5 d，在距胚头1 cm两条卵黄静脉之间的卵壳投影部位磨切暴露尿囊膜，制成假气室，用无菌滤纸封闭窗口，制成鸡胚尿囊膜模型，备用。

Biofilm is fragmented and mainly composed of zoogloeas on the cracks and concaves of the filter media. The bacteria in biofilm or activated sludge of aerobic filter are mainly bacilus and filamentous bacteria.

滤料上的生物膜是不连续的，微生物主要以菌胶团的形式存在于滤料上的孔洞内和表面凹陷处；无论是滤料上的生物膜，还是滤床孔隙内的活性污泥，其中的细菌以各种杆菌及丝状菌为主。

It can also explain competitions for space and oxygen between ammonia-oxidizers and nitrite-oxidizers and their evolution in nitrifying biofilm.

模型很好地解释了硝化生物膜中氨氧化菌与亚硝酸氧化菌对空间和氧的竞争，以及它们在生物膜中的演变关系。

Using centrifugal casting method, hollow fiber membrane is encapsulated into dialyzers, and prepared by the water, urea, Lysozyme and BSA simulated liquid form, which uses Lysozyme instead of β_2-MG, BSA instead of human serum albumin. In this paper, the simulation solution is used to evaluate dialysis performance of PES hollow fiber membrane dialyzers.

采用离心浇铸法将中空纤维膜封装成透析器，用溶菌酶代替β_2~-微球蛋白，用牛血清白蛋白代替人血清白蛋白，制备由纯水、尿素、溶菌酶和牛血清白蛋白构成的模拟液，用此模拟液来代替患者血液，对本文研制的聚醚砜中空纤维膜透析器的透析性能进行评价。
