大肠杆菌尿

Subtilase cytotoxin is produced by E. coli bacteria that cause bloody diarrhoea and haemolytic uraemic syndrome in humans.

亚麻酶胞毒素由大肠杆菌产生，能造成严重腹泻和溶血性尿毒综合症。

Methods: The traditional method of chronic serum sickness was modified by adding followings: one kidney removed, intraperitoneal inject LPS etc., and the effect of Shenhua Tablet on 24h proteinuria, blood biochemical indices, kidney function, pathology and immunofluorescence changes was observed compared with Fosinopril, and and the effect of Shenhua Tablet on the ED-1 positive cell number in the glomerulus, protein and mRNA expression and activation of Stat3 and protein and mRNA expression of TIMP-1 in the kidney tissue, and a-SMA positive mesangial cells were observed compared with Fosinopril using western blot, northern blot and immunohistochemistry methods.

对传统的大鼠慢性血清病肾炎模型制作方法进行以下改良：切除大鼠一侧肾脏、腹腔注射大肠杆菌内毒素、以及改尾静脉注射为腹腔注射。与西药福辛普利作对照，观察中药肾华对改良慢性血清病肾炎大鼠尿蛋白、血生化、肾功能、肾脏病理变化的影响。并通过免疫组化、Western蛋白印迹及Northern杂交方法，观察中药肾华对改良慢性血清病肾炎大鼠肾组织肾小球内炎细胞浸润、Stat3蛋白与基因表达及活化、以及其下游调控的TIMP-1蛋白与基因表达、系膜细胞增殖的影响。

Glioma is still one of refractory disease in the neurosurgical field; the development of new primary and adjuvant treatment is vital. Recently, the gene therapy of glioma is developed rapidly and there are many methods about the gene therapy that include: suicide gene therapy, immunologic gene therapy, drug resistangce gene therapy, angiostatin gene therapy and so on. The sucide gene therapy is the most potential approach of antitumer, these nonmammalian genes encode enzyme that convert nontoxic prodrugs into highly toxic metablites. Cells transfected with suicide genes are targeted for specific negative selection, witch can be induced by administrtion of the corresponding produg. Among the enzyme/produg combinations, two of the best characterized system are herpes simplex virus thymidine kinase /ganciclovir and Escherichia coli cytosine deaminase /5-flourocytosine (5-FC). The formor can convert the antiviral nucleoside analogs acyclovir , ganciclovir to their nucleoside monophosphate derivatives, the monophosphate forms are subsequently phosphorylated by endogenus cellular kinases to triphosphates, these molecules are potent inhibitors of DNA synthesis.

近年来脑胶质瘤的基因治疗发展迅速，应运而生的方法有自杀基因、免疫基因、多药耐药基因以及抗血管生成基因等，其中自杀基因被认为是最有前景的基因治疗方法，它又称病毒介导的酶／药物前体疗法，是利用转基因技术将哺乳动物细胞中所不含有的自杀基因转入到哺乳动物肿瘤细胞中，该基因表达的产物可将无毒的药物前体转化为毒性药物，从而选择性杀伤该肿瘤细胞，常用的自杀基因有单纯疱疹病毒-胸苷激酶基因和大肠杆菌胞嘧啶脱氨酶基因，前者催化无毒性抗病毒核苷类似物如丙氧鸟苷、无环鸟苷等成为单磷酸核苷衍生物，然后在内源性细胞激酶作用下转化为具有明显毒性的三磷酸核苷，作为DNA合成链的终止剂和DNA合成酶的抑制剂，干扰细胞DNA的合成；后者编码的胞嘧啶脱氨酶可催化5-氟胞嘧啶（5-FC）脱氨成为5-氟尿嘧啶（5-FU），然后代谢为有毒性的5-氟尿嘧啶-5′三磷酸（5-FUTP）和5-氟-2′脱氧尿嘧啶-5′磷酸（5-FdUTP），5-FUTP通过与UTP竞争性结合而抑制mRNA和tRNA的合成，5-FdUTP则作用于胸苷合成酶，导致TMP衰竭而阻止DNA的合成，最终诱导肿瘤细胞凋亡。

Diarrhoea-associated haemolytic uraemic syndrome is most commonly caused by E.

腹泻相关性溶血尿毒综合徵最常见的致病菌是 O157：H7 大肠杆菌。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
