Methods: 1 Ornidazole and Pefloxacin are divided to six levels, in order to measure the changes of antiblastic indexes of different proportions of Ornidazole and Pefloxacin against Pg, Fn, Pi, and Peptostreptococcus spp. Statistical test is used to seek the indistinctive ranges of antibacterial activities of Ornidazole and Pefloxacin against those four kinds of typical periodontal pathogens, and to find the suitable proportion.

1奥硝唑和培氟沙星各自分为6水平，测量两种药物不同比例水平混合后对牙龈卟啉单胞菌，具核梭杆菌，中间普氏菌，消化链球菌标准菌株的抑菌指标变化，通过统计检验找出奥硝唑和培氟沙星不同配伍抑菌指标的无差别比例范围，并找出合适比例。2检测两种药物以及其合适的比例对厌氧菌标准菌株和42株临床分离的非厌氧菌的MIC和MIC50。

Results: The proportion of Gram-negative bacilli rose obviously, so did the opportunistic pathogen's and Yeasts detected rate. Most drug sensitive tests showed the drug-fast rate turned to be high. Escherichia coli, Salmonella and Citrobacter resistant and so on to fluoroquinolones was 57%~97%. These bacteria to imipenem showed excellent activity. Meticillin-resistant-staphylococcus resistant to ciprofloxacin, norfloxacin, clindamycin, tetracycline, erythromycin, cefazolin and ampicillin were 40.9%, 42.4%, 63.6%, 72.2%, 85.9%, 100.0% and 100.0%, respectively Streptococcus and Enterococcus resistant to major β-lactams-penicillin, aminoglycosides, macrolides, tetracyclines and sulfonamides were between 36.0% to 100.0%.

结果：革兰阴性杆菌比例显著升高，条件致病菌和酵母样真菌检出机会显著增多；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和枸橼酸杆菌等革兰阴性杆菌对喹诺酮类药物的耐药率达57%~97%，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、头孢唑啉和氨苄西林的耐药率分别为40.9%、42.4%、63.6%、70.2%、85.9%、100.0%和100.0%；链球菌和肠球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物均呈高度耐药，耐药率在36%~100%。

To Dec. 2003 years in Yuxi city People's Hospital. RESULTS: The proportion of G－ bacilli were much. The opportunistic pathogen's and Yeasts detected rate rose obviously. Most drug sensitive tests showed the drug-fast rate turned to be high. Escherichia coli, Salmonella and Klebsiella and so on to fluoroquinolones was 50～97.7%. These bacteria to imipenem showed excellent activity. MRS resistant to ciprofloxacin, norfloxacin, clindamycin, tetracycline, erythromycin, gentamycin, trimeth/sulfa and cefazolin were above 50%. Streptococcus resistant to major β-lactams-penicillin, aminoglycosides, macrolides, tetracyclines and sulfonomides were highness.

结果：G－杆菌比例居多，条件致病菌和酵母样真菌检出机会显著增高；药敏结果显示多数临床细菌对常用抗生素的耐药趋势在不断上升；大肠埃希菌、沙门菌和克雷伯菌等G－杆菌对喹诺酮类药物的耐药率在50％～97.7％，亚胺培南则对阴性杆菌有较高的敏感覆盖率；耐甲氧西林葡萄球菌对环丙沙星、诺氟沙星、氯洁霉素、四环素、红霉素、庆大霉素、复方新诺明和头孢唑啉的耐药率均在50％以上，链球菌对多数β内酰胺类青霉素、氨基糖苷类、大环内酯类、四环素类以及磺胺类药物呈高度耐药。

Ciardiello and colleagues tested ZD1839, a quinazoline derivative, in combination with cytotoxic agents that had differing mechanisms of action (cisplatin, carboplatin, oxaliplatin, paclitaxel, Taxotere, doxorubicin, etoposide, topotecan, and tomudex).

Ciardiello及其同事试验了将一种喹唑啉衍生物ZD1839与作用机制不同的细胞毒素药物（顺铂、卡铂、奥沙利铂、紫杉醇、泰索帝、阿霉素、依托泊甙、拓扑特肯等）合用。

In the process, 2, 4-difluoroaniline is used to carry out ammoniated reaction. Then through a series of similar reactions, the important intermediate of temafloxacin, which is called 7-chloro-6-fluoro-1-(2, 4-difluorophenyl)-1, 4-dihydro-4-oxo-3-quinoline acid, is gained.

与环丙沙星和二氟沙星类似，用2，4-二氟苯胺进行胺化反应，再进行一系列类似的反应，制得合成替马沙星的关键中间体7-氯-6-氟-1-（2，4-二氟苯基）-1，4-二氢-4-氧代喹啉-3-羧酸。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
