Taking Shewanella and Geobacter as examples, this paper reviewed three kinds of possible mechanisms of microbial enzyme-catalyzed dissimilatory Fe reduction and its molecular regulation, i.e., direct contact between microbial cell and Fe oxides, siderrophores, and electron shuttling compounds. Many membrane-bound cytochrome proteins are involved in the dissimilatory Fe reduction, forming a complicated regulation network.

以希瓦氏菌和地杆菌为例，本文综述了3种异化Fe还原的酶促反应机制及其分子调控机理：异化Fe还原菌与Fe氧化物直接接触机制、电子穿梭体的作用机制、铁载体作用机制，多种膜蛋白特别是多血红素的细胞色素蛋白参与微生物的异化Fe还原过程，并形成复杂的调控网络。

objective to explore the reasonable utilization of cephalosporins in chronic renal failure patients with cephalosporin encephalopathy.method we retrospectively analyzed the clinical characteristics of 29 crf patients,who developed encephalopathic syndrome and was treated with cephalosporin.results the encepha1opathic syndrome include (1)mental confusion in 4 cases;(2)unconsciousness in 2 cases;(3)seizure in 23 cases.physical examination did not show signs of cerebral focal injury.computed tomography of the brain in 29 patients did not show acute lesions.the state of neurotoxicity was completely recovered after discontinuation of cephalosporins.conclusion cephalosporins used in conventional doses or reduced doses can cause temporary encephalopathy in patients with crfwhich might due to prolongation of drug half life.

目的 通过研究慢性肾功能衰竭患者抗生素脑病的发病机制和临床特点，探讨头孢菌素在crf患者中的合理应用。方法 29例crf患者在使用常规剂量或减量使用头孢菌素后出现神经精神症状，诊断为抗生素脑病，将其临床资料进行回顾性分析。结果神经精神症状表现多样：(1)精神异常4例，表现为胡言乱语、烦躁不安、睡眠倒错；(2)意识障碍2例，表现为嗜睡、昏睡、神志不清；(3)癫痫样抽搐23例，表现为肌阵挛、全身抽搐、癫痫样发作；部分患者同时出现几组症状。所有患者均无神经系统定位体征，行颅脑ct检查无急性病变。

In this paper, an escherichia coli-saccharopolyspora erythraea shuttle vector containing the erya promoter region was constructed using the enhanced green fluorescent protein gene as a reporter. the shuttle plasmid was transformed into sac.erythraea a226 and streptomyces lividans jt46 by peg mediation, respectively. fluorescence microscopy confirmed that the egfp was expressed in both strains.

本文克隆了erya基因的启动子perya，以绿色荧光蛋白基因为报告基因，构建了大肠埃希菌-糖多孢红霉菌穿梭型质粒。peg介导原生质体转化法将穿梭型质粒分别转入糖多孢红霉菌a226与变铅青链霉菌jt46，荧光显微镜检测发现，此启动子在两菌株中都具有功能。
