Avermectin are 16-membered pentacyclic lactone compounds produced by Strephomyces avermitilis, which have extensive and high effect on many kinds of insect and mite.

阿维菌素是从阿维链霉菌的发酵产物中分离出来的16元大环内酯类抗生素，对多种动物寄生虫及农业害虫害螨有很高的杀虫活性，但是该药剂光照易降解而持效期短。

Tetrahydroisowuinolin derivatives and phthalide derivatives were designed and synthesized on the basis of a PDE4 inhibitor pharmacophore model set up through computer simulation. Some tetrahydroisowuinolin derivatives synthesized were evaluated on their activity against PDE4 for study on the structure-activity relationship.(7-cyclopentyloxy)-6-methoxy-3,4-dihydroisoquinolin-2(1H)-yl(4-hydroxy-3-methoxyphenyl)methanone (155) and Methyl 7--6-methoxy-2-(4-methoxy- benzoyl)-1-phenyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylate (170) showed good activity against PDE4, which were chosen as the lead compounds to design and synthesize another analogs in order to develop selective PDE4 inhibitors with better activity.

分别设计合成了以四氢异喹啉和氨基苯酞为骨架的两类小分子杂环化合物，并对部分四氢异喹啉衍生物测试了其相关的生物活性，初步确定了其构效关系，发现了两个对PDE4有较好抑制活性的先导化合物(7-cyclopentyloxy)-6-methoxy-3，4-dihydroisoquinolin-2(1H)-yl(4-hydroxy-3-methoxyphenyl)methanone (155)和Methyl 7--6-methoxy-2-(4-methoxy- benzoyl)-1-phenyl-1，2，3，4-tetrahydroisoquinoline-3-carboxylate (170)。

Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.

结果 共检出致病菌383 株，革兰阴性细菌占8411 %，其中非发菌占5114 %，肠杆菌科占3216 %，革兰阳性球菌占1218 %，其中MRSA和MRSE 占615 %，真菌占311 %；前5 位致病菌分别为铜绿假单胞菌(3013 %)、鲍氏不动杆菌(1115 %)、肺炎克雷伯菌(1017 %)、大肠埃希菌(716 %)、金黄色葡萄球菌(618 %)等；药敏结果显示这几类菌株的多重耐药现象严重，较为敏感的抗菌药物有亚胺培南/西司他丁、阿米卡星、哌拉西林/他唑巴坦、头孢他啶、头孢吡肟、头孢哌酮/舒巴坦、环丙沙星及替卡西林/克拉维酸等，革兰阳性细菌均对万古霉素敏感；迟发性VAP 的混合培养比例显著高于早发性VAP。

N-substituded thioacridones with five different structures were synthesized via a route involving Ull-man reaction, cyclization, N-alkylation and sulfurization. The structures of each thioacridone were identified with IR and MS. The results from UV-spectrophotometry show that the five N-alkythioacridones all have stronger absorption in the visible light region.

采用乌尔曼反应、酸催化环化、N-烷基化和硫代化四步反应路线合成了5种不同结构的N-取代硫代吖啶酮，利用IR和MS分析手段表征了其结构，UV分光光度计的测定结果表明5种硫代吖啶酮在可见光区都有较强的吸收。

Drivers used to the low-end torque of a larger-displacement motor, or a turbocharged motor in a Saab or Audi, will find there's a bit to get used to with the tach needle's desire to tickle the far end of its range.

司机用于低端扭矩大排量发动机，或涡轮增压发动机的萨博或奥迪，会发现有位习惯于与环针的愿望发痒尽头的范围。

Intelligent control is aimed to solve the task-oriented control problems in complex environments which are unstructural, uncertain and have strong interactions with the plants.

摘要智能控制是在常规控制理论与技术基础上的进一步发展与提高，目的是在非结构化、不确定性与控制对象有强相互作用的环境中实现过程任务的闭环自动控制。
