Results: Against most of gram-negative bacteria and anaerobe, pipercillin/sulbactam showed stronger activity than that of ampicillin/Sulbactam and pipercillin.

结果： 哌拉西林/舒巴坦对产酶革兰阴性需氧菌及厌氧菌的体外抗菌活性均高于哌拉西林和氨苄西林/舒巴坦；哌拉西林与舒巴坦的不同配比对其抗菌活性影响不大；哌拉西林/舒巴坦对临床常见产酶菌的MIC和MBC非常接近。

But French navire and batiment are masculine, and Romance language terminology for small ships is "almost invariably" variable: From el buque to la barca and el barco; from le bateau to la barque, there is considerable confusion over whether boats are female or male.

和navire和batiment则是阳性，而在罗曼语系中，指"小"船的词语其性别"几乎总是"可变的：从el buque到La barca 和el barco，从 le bateau到 le barque，在船是阴性还是阳性这个问题上存在着相当大的混乱。

Resistance ratio of common Gram-negative bacilli to CAZ is high and tend to increase further.

结论常见革兰阴性杆菌对CAZ的耐药率有逐渐上升的趋势，要严格限制该药的不合理应用。

RESULTS:（1）Three KDR-siRNA expression vectors were digested by Nde Ⅰ and Sma Ⅰ and produced two fragments of 713 bp, 5 480 bp and 2 403 bp, 3 790 bp, respectively, which were congruous with expectation.

KDR-小干扰RNA对A549细胞中KDRmRNA水平的影响：与阳性对照组、阴性对照组、空白对照组和正常对照组的A549细胞相比，KDR-siRNA1，2，3表达载体转染后的A549细胞KDR基因表达水平均明显受到抑制，抑制率分别为64%、81%和72%，其中以KDR-siRNA2抑制作用最为明显。

Two different murine models (IFN γ or IL 4 gene knockout C57BL/6 mice,15 mice each strain) were contagiously infected with P.carinii by cohousing with P.carinii positive mice for 3,5,7 weeks as well as 15 gene un knockout C57BL/6 mice for infection control group.

分别用IFN γ或IL 4基因敲除的C5 7BL 6小鼠(各 15只作为动物模型)与未经基因敲除的C5 7BL 6小鼠(15只作感染对照组)，以密切接触的方式，使小鼠自然感染卡氏肺孢子虫；同时设非感染组 15只小鼠作阴性对照。

RESULTS The average bacteriacolony forming unit per milliliter in dialysis fluid from the dialyzer inlet , outlet and reverse osmosis was 486 CFU/ ml ,490 CFU/ ml and 103 CFU/ ml , respectively. The common isolated bacteria were Bacillus subtilis , diphtheroid bacilliand some Gram2negative bacilli.

RESULTS: ADMSCs at passage 3 were positive for CD13, CD59 and CD44, but negative for CD34 and HLA-DR. Chromosomal morphous, structure and number were normal, showing diplont structure. Under the microscope, there were complete Golgi complex, plenty of rough endoplasmic reticulum, and some glycogen granules in cytoplasm.

结果：第3代脂肪间充质干细胞CD13，CD44，CD59均呈阳性表达，而造血干细胞表面标志CD34及成纤维细胞表面标志HLA-DR均呈阴性表达；染色体的形态、结构和数目均未见异常，呈二倍体结构；镜下可见完整的高尔基复合体，数量较多的粗面内质网，部分糖元颗粒分布在胞浆中。

CAS is currently rely mainly on the diagnosis of coronary provocation test, including acetylcholine and ergonovine test pilot, domestic scholars have found in 201Tl SPECT myocardial perfusion imaging in the cardiac stress test was reverse redistribution is CAS One of the characteristics of patients, if the combination of exercise electrocardiography test negative as well as the rest of the clinical features of chest pain, diagnosis of coronary artery spasm highest sensitivity and can be made respectively 98% and 90% respectively.

目前诊断CAS主要依靠冠状动脉内激发试验，包括乙酰胆碱试验与麦角新碱试验，国内学者发现在201TlSPECT心肌灌注显像心脏负荷试验中呈反向再分布现象是CAS患者的特点之一，若结合运动心电图试验阴性以及静息性胸痛的临床特点，诊断冠冠状动脉痉挛的灵敏度以及特意度分别可以达到98％和90％。

Results:The spective sensitivity value of cTnI,CK-MB and Mb were 93.3%,86.7% and 78.3%;the spective specificity value were 100%,100% and 88.0%;the sensitivity and specificity value of both cTnI and Mb were 96.7% and 88.0%;the sensitivity and specificity value of all cTnI,Mb and CK-MB were 98.3% and 88.0%;the positive and negative expectative value were 95.2% and 88.0%.
