PART 2:The molecular mechanisms of Nontypeable Haemophilus influenzae induced inflammatory response in respiratory epithelial cells Objective:Nontypeable Haemophilus influenzaewas traditionally considered as an extracellular pathogen in respiratory infections.In this study,we established a model of infected cells to confirm NTHI was also a facultatively intracellular pathogen.Mitogen activated protein kinasesare the important signal transduction pathway in mediating inflammatory response induced by NTHI in respiratory epithelium.In this study,we elucidate the impact of NTHI,and its SCF and EP on the expression of MAPK and subsequent proinflammatory mediators.

第二部分：NTHI致呼吸道上皮细胞炎症反应的分子机制研究目的：通过建立呼吸道上皮细胞株的体外NTHI感染模型，确认NTHI在细胞内的存活，观察NTHI及其组分(可溶性胞质成分SCF、外膜蛋白EP)对呼吸道上皮细胞MAPK信号传导通路和后续的前炎症因子表达的影响，并应用特异性ERK-MAPK抑制剂U0126、p38 MAPK抑制剂SB203580特异性阻断下游MAPK信号传导通路，观察它们对呼吸道上皮细胞分泌前炎症因子表达的影响。

The re-suits showed that IL level in serum of Ⅰ group goats decreased, whereas that of Ⅱ group goats increased, TNF-α levels in serum and IL-2 in supernatant with proliferation of PBL of goats increased after infection. PBL of goats was responsible for antigen 1 week after infection. Immune response of PBL of goats infected with Fasciola hepatica on the special and non-special antigen obviously increased. The results suggested that TNF-α would participate in the course of liver damage caused by Fasciola hepatica.

结果表明，山羊试验感染肝片吸虫后，Ⅰ组山羊血清IL-2水平在感染后有所下降，而Ⅱ组山羊血清IL-2水平在感染后有所升高；感染不同剂量肝片吸虫的山羊血清TNF-α水平和淋巴细胞IL-2分泌水平均有不同程度的升高，在感染后第1周淋巴细胞就有反应，并且对非特异性刺激原和特异性刺激原的应答都有显著升高。

For Streptococcus penumoniae、Hemophilus in0fluenzae、Staphylococcus aureus、Acinetobacter baumannii、Pseudomonas aeruginosa,the sensitivety of Tem-PCR was 100%、41.7 %、11.1%、50.0 %、66.7 % respectively; the specificity was 84.0%、81.7%、98.9%、95.2%、98.9% respectively. Tem-PCR was more sensitive than culture in the detection of Streptococcus penumoniae 36/19.1% vs.

腐蚀性食管炎的ECE相对于BE的灵敏度，特异性，阳性预测值以及阴性预测值分别为50%， 90%， 56%，和88%，食道裂孔疝的ECE相对于BE的灵敏度，特异性，阳性预测值以及阴性预测值分别为54%， 67%， 83%，和 33%。

During embryonic development, Hox proteins can interact with different cofactors and regulate downstream gene expression in a tissue specific manner.

在胚胎发育过程中，Hox蛋白实现时间特异性及组织特异性基因表达调控功能的机制之一是与不同的辅助因子相结合。

In this study, oral tolerance was induced by tube-feeding transgenic mice with 0.5mg/day OVA protein daily, simultaneously sensitized by OVA protein with aluminum hydroxide. Oral-administered OVA protein (0.5mg/day for 5 or 10 consecutive days) resulted in significant lowered airway hypersensitivity as well as reduced inflammative cells infiltration, titer of serum OVA-specific IgE, IL-5 secretion in bronchoalveolar lavage fluid, and IL-4 secretion in splenocyte.
