The response of HNEC to the stimulation of LPS shows dosage dependence, and stimulation of LPS with suitable concentration benefits HNEC secreting Th1/Th2 cell factors to maintain the balance; The stimulation of LPS with too high and too low concentrations would cause unbalanced secretion of Th1/Th2 cell factors, which might be the pathopoiesis mechanism of gram negative bacilli in chronic rhinitis and rhinosinusitis.

LPS对HNEC的刺激反应与浓度呈剂量依赖性，适当浓度的LPS刺激有利于HNEC分泌的Th1/Th2细胞因子维持平衡状态；过高或过低浓度的LPS刺激可诱导HNEC的Th1/Th2细胞因子失衡分泌，这可能是GNB在慢性鼻、鼻窦炎的致病机理。

objiective:to investigate the causes of the contamination of dialysis fluid.methods the level and species of bacteria were detected.results:the pathopoiesis bacteria and pathopoiesis bacteria in condition were identified in dialysis fluid,fluid b.offlake of soft water and preparing container.conclusions the contamination of'dialysis fluid is related with the untimely change of the filter in soft water machine and membrane of reverse osmosis,the contamination of fluid b.

目的：调查透析液和透析用水细菌污染的原因。方法：按《医院感染管理规范》的要求检测并鉴定致病菌。结果：透析液和透析用水、b液、软水口、配液容器培养出致病菌和条件致病茵。结论：血液透析液和透析用水细菌污染与软水机过滤器和反渗膜使用时间过长引起破损，未能及时更换，以及b液配制过程中细菌污染有关。

The character of hemagglutination of the virus could be inhibited by the antiserum of Newcastle disease virus.According to the international standard and method of virulence judgement of NDV, we measured the average death time、the minimal lethal dose and the median infective dose(EID50) of chicken embryos and the intracellular inoculation pathopoiesis index of 1-day-old chicks.

参照国际上规定的新城疫病毒毒力判定标准及其方法对分离毒株ZH1、ZH2进行了鸡胚最小致死量和平均死亡时间、鸡胚半数感染量(EID50)以及1日龄鸡脑内接种致病指数测定，结果ZH1、ZH2株的MDT为52h和44 h，EID50为106.4/ 0.1mL和108.64/ 0.1mL，ICPI为1.93和1.975。

This paper is mainly comprised of two components:preparation of models of rats suffering from deficiency of spleen Yang;comparison of the pharmacodynamics impacts of different Lizhong Pills formulations made up by dried ginger or its different components in Lizhong Pills to the different groups of the models.1 Establish the model of deficiency of spleen YANG induced by " cypsum fibrosum and anemarrhenae " with complex factors1.1 ObjectivesWith using heat-clearing and fire-purging drug cypsum fibrosum and anemarrhenae,insteading of the common usage of rhubarb and folium sennae,accompanied with irregular diet and overstrained,the model of deficiency of spleen-YANG is to be established,which is much close to the pathopoiesis theory of " frigidity and chilly damaging yang,irregular diet injuring qi,overstrain impairing the spleen" in TCM.1.2 MethodsModel rats is fully fed every other day,given the molding drug of cypsum fibrosum -anemarrhenae(concentration 4:1) with 3 different frequency,and arranged to swim everyday in 25℃water until exhausted(performing as spitting bubble 3 times continuously or sinking unable to float by itself).

全文共分为脾阳虚模型的制备和干姜及其成分对理中丸药效学影响的比较两大部分。1&石膏-知母&复合法脾阳虚模型的制备1.1目的以清热泻火药石膏-知母代替常用的大黄、番泻叶类苦寒泻下药，并结合饥饱失常、劳倦过度的方法进行造模，以期建立更符合中医&寒凉伤阳、饥饱伤气和劳倦伤脾&致病思路的中医脾阳虚证候模型。1.2方法模型动物隔日足量喂食，每日在25℃水中游泳，直至大鼠连续三次吐泡下沉，或沉入水底，3秒内不能自行浮出水面，并以三种不同给药频率灌胃给予石膏一知母煎液，比较石膏-知母不同给药方法对制备脾阳虚模型的影响。

Histopathological lesions related to swine influenza-induced lesions consisting of epithelial cells damage, airway plugging and peribronchial and perivascular mononuclear cell infiltration were present in both infected groups.

为了研究禽流感病毒H5N1是否会通过传染给猪再传染给别的哺乳动物，我们利用细胞培养基观察禽流感病毒和猪流感病毒的生长情况，并对比他们对小鼠的致病力。
