objective to discuss perioperative complication and management of patient with high risk copd following esophagectomy.methods 45 patients with high risk copd underwent esophagectomy with epidural block combined with general anesthesia.perioperative treatment included smoking cessation,chest physiotherapy,prevention and control of infection of air way and appropriate bronchodilators of air way,breathing exercises,nutrition support and oxygen therapy.painkiller was instilled after surgery,early exercises,ensuring unobstruction of the air way,mechanical ventilation was applied when needed.results 3 had hypoxaemia in operation.after surgery,all patients had spo2 somewhat declined.6 had lung infection.6 were removed of bronchial secretion by bronchoscope.2 were supported by ventilator by using intubation.2 underwent tracheotomy.1 had disturbances of acid base balance and treated by using hydrochloric acid muriatic acid.all patients recovered rather smoothly and discharged from hospital.conclusion high risk copd is not the absolute contraindication of esophagectomy.active management before and after surgery ensures the safety and recovery of patients.

目的 探讨重度慢性阻塞性肺疾病简称慢阻肺病人食管切除术围手术期常见并发症及其处理。方法 45例重度慢阻肺的病人在全麻联合硬膜外阻滞下进行开胸食管切除手术，围手术期处理包括术前戒烟、胸部理疗、预防和控制呼吸道感染、解痉化痰、呼吸功能锻炼、营养支持和氧疗；术后硬膜外镇痛、早期锻炼、保持呼吸道通畅，部分病人予以呼吸支持。结果术中3例出现低氧血症。术后所有病人pao2均有不同程度的下降，6例出现肺部感染，6例行纤维支气管镜吸痰，2例通过气管插管给予呼吸机支持，2例行气管切开术，1例酸碱平衡紊乱使用盐酸精氨酸治疗。所有病人均痊愈出院。结论重度慢阻肺病人并非开胸食管切除手术的绝对禁忌证，积极的术前准备和严格的术后管理可减少和控制术后急性发作，有助于确保此类病人的围手术期安全和康复。

实验结果表明，高频间歇式曝气方式在抑制了硝酸细菌的活性的同时也消除了亚硝酸盐浓度和pH大幅波动对亚硝酸细菌和厌氧氨氧化细菌活性的影响；在曝气阶段，溶解氧浓度被控制在1.2～1.4mg·L-1，亚硝酸细菌成为主体细菌，亚硝酸盐积累；在缺氧阶段，随着溶解氧浓度迅速降低，厌氧氨氧化细菌成为优势菌种，曝气阶段积累的亚硝酸盐与氨氮同时被去除。

目的观察体外乏氧培养条件下食管鳞癌细胞系EC9706中HIF-1α和VEGF的表达，探讨HIF-1α在低氧条件下对食管鳞癌血管生成的调控作用。

Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.

针对常规甲烷催化转化和氧化偶联制备含氧化合物的问题，遵循国际化学科学研究前沿"绿色化学"原则，采用自然界存在丰富的CH_4、H_2O和O_2为原料，在绿色友好的常温大气压无任何催化剂的条件下，采用强电场电离放电加速电子及其激励气体分子的极端物理手段，在反应腔体内进行无任何环境污染的非平衡等离子体化学反应，将气体分子激发、电离、离解成CH_4~+、CH_3~+、CH_4~·、H_2O~+、H_2O~·、O_2~+、O(~1D)等活性粒子，生成气态烃及含氧碳氢化合物，整个反应过程实现零污染、零副产品。

The Molar conductivity indicates that all the complexes are nonelectrolyte. IR spectra show the ligand is bonded with RE ion through its oxygen atom in hydroxyl group of phenol; NO3 is coordinated as a symmetrical chelating bidentate group; the coordinated atoms of DMF and DMSO are the oxygen atoms in carbonyl and sulfoxyl groups. Fluorescence spectrum suggests that the Tb3+complexes have characteristic luminescence and its fluorescence intensity is enhanced after doping with La3+, Gd3+, Y3+, influence of doping ions and neutral ligands have also been discussed.
