阴性

The recombinant RSV vaccinia virus VMS11G75F was constructed strictly according to the rules of biological products and all tests for contamination by bacteria, Chicken leucosis virus and mycoplasma gave negative results, so that vaccinia recombinant VMS11G75F could be a candidate of recombinant RSV live vaccine for human test.

HSV重组痘苗病毒VMS11G75F是严格按照人用疫苗株程序构建而成，并对多种外源因子污染(包括：细菌、鸡白血病病毒、支原体等)进行了检查，均为阴性，因此是一株可供人体实验观察的RSV基因工程活疫苗候选株。

Hemolysis or lipemia did not seem to influence the measurement, and there was no difference between anti-HBc-positive and -negative individuals.

溶血或血脂过高似乎并没有影响测量结果，在抗- HBc阳性和阴性个体中也一样。

It was found that there were some differences between the amplified bands of Liquidambar formosana which grew in the place of the altitudes from 100 m to 300 m and in the place of the higher altitudes from 400 m to 700 m, while there was no obvious difference among the amplified bands of Liquidambar formosana's samples (3 samples were from shade conditions and 3 from sunlight conditions) which were from the same altitude (710 m).

结果发现：生长於海拔100~300 m的枫香的扩增谱带与生长於高海拔(400~700 m)的略有差异，而在相同海拔(710 m)的3个阴性条件样品和3个阳性条件样品间，其扩增谱带没有明显差异。

To investigate the genetic differences between the Liquidambar formosana populations at different altitudes and in the same light conditions in Wuzhi Mountain of Hainan, the samples of Liquidambar formosana at 7 altitude levels and the 6 samples (among which, there were 3 samples from shade conditions and 3 from sunlight conditions) from the same altitude (700 m) were made a study in molecular biology by RAPD method, with 50 random primes in use.

为了解五指山不同海拔下枫香居群之间的遗传差异，用50个随机引物，应用随机扩增多态性DNA方法，分别对7个海拔梯度、相同光照条件下的枫香样品和710 m海拔高度的6个枫香样品（3个阴性条件样品和3个阳性条件样品）进行了分子生态学研究。

Results : Ten articles about lobulation sign were included,with 9 independent researches and a total of 747 subjects(including 495 cases of peripheral lung cancer and 252 cases of pulmonary tuberculoma).

分叶征和深分叶征的汇总敏感性分别为0.78、0.50，汇总特异性分别为0.82、0.94，汇总阳性拟然比分别为3.42、6.22，汇总阴性拟然比分别为0.31、0.56，汇总的诊断比值比分别为14.2、13.1。

Objective :To assess the overall value of lobulation sign and deep lobulation sign in the differential diagnosis of peripheral lung cancer and pulmonary tuberculoma in CT images.Methods : Firstly , articles about CT differential diagnosis between pulmonary tuberculoma and peripheral lung cancer were selected ,which were published in the period(from January 1990 to December 2008),and useful data were extracted.Then Meta-analysis was done using Meta-disc software,and SDOR value calculated.

方法搜集1990年1月至2008年12月国内外公然发表的关于四周型肺癌与肺结核球CT鉴别诊断的文献，对文献进行筛选，应用Meta-disc软件对符合条件的原始研究进行质量评估、异质性检验，计算阳性似然比、阴性似然比和诊断比值比，最后汇总敏感性和特异性，绘制SROC曲线并计算曲线下面积来综合评价分叶征及深分叶征在CT检查中对于四周型肺癌与结核球鉴别诊断的价值，进行敏感性和特异性分析。

Result The fold activation value of luciferase of rifampin group was statistically different from control group and DMSO group.

结果经利福平处理的细胞裂解物荧光素酶比活性值与阴性对照组和溶剂组差异显著。

Was negative. It's not lupus.

的结果是阴性不是狼疮
