阴性的

Results In 585 staphylococcus, there were 406 staphylococcus aureus, which including 387 methicillin sensitive staphylococcus aureus and 19 methicillin resistant staphylococcus aureus. And there were 179 coagulase negative staphylococcus, including 20 methicillin sensitive coagulase negative staphylococcus and 159 methicillin resistant coagulase negative staphylococcus.

结果 585株葡萄球菌中，金黄色葡萄球菌406株，其中甲氧西林敏感的SA387株，甲氧西林耐药的SA19株；凝固酶阴性的葡萄球菌179株，其中甲氧西林敏感的CNS20株，甲氧西林耐药的CNS159株。

The results prove that CNHK500 has highly proliferation selectivity and potent cytolysis effect on breast cancer in vitro.

在感染CNHK500的端粒酶阴性的正常成纤维细胞株中未检测到E1A基因表达，在端粒酶阳性的感染CNHK500的乳腺癌细胞株中能够检测到E1A基因的表达；CNHK500可以选择性地在缺氧条件下表达E1B。

The DCs in gastric cancer groups with lymphangial invasion were lower than that of without lymphangial invasion.

有淋巴管侵犯的胃癌组中树突状细胞浸润密度低于无淋巴管侵犯的胃癌组（P=0.011）。p53表达阳性的胃癌组树突状细胞浸润密度低于p53表达阴性的胃癌组（P=0.032）。50例患者5年生存率中，树突状细胞高浸润组（≥10.16／mm^2）明显好于树突状细胞低浸润组（〈10.16／mm^2）（P=0.001）。

But it is doubt that the speciality and stability for the outcome of detecting BDV ORF I genome.

但对另一编码P40蛋白序列的检测结果的特异性和稳定性还不肯定，我们通过对先前检测BDV ORFⅡ基因片段为阳性或阴性的神经精神病人和健康献血者进行了BDV ORFⅠ基因中部片段的检测。

Desmin, the marker of myoblasts, was adopted to identify the expression of specific marker protein of sarcoblast desmin with immunohistochemistry. Desmin negative cell clones were removed, and desmin cell clones were cultured continuously with the culture fluid replaced once every other day.

采用成肌细胞特异性标志抗原desmin免疫化学染色，鉴定成肌细胞标志蛋白——结蛋白的表达，弃去desmin阴性的细胞克隆，继续培养desmin阳性的细胞克隆，隔天换液1次，7 d进行酶消化传代，获得大量扩增的细胞，并可冻存复苏，用于实验。

Sometimes, they showed seronegative for all HBV markers. The definition of occult HBV is based on the existence of HBV DNA in the serum, lymphatic cells and/or liver tissue in the absence of serum HBsAg.

隐匿性HBV感染的定义为在血清学检测HBsAg阴性的情况下，在感染者的血清、淋巴细胞和/或肝组织标本中检测到HBV DNA的存在。

Antiviral therapy for 12 weeks is generally effective in treating patients who are HCV RNA negative after 4 weeks of treatment; lengthier courses could be needed for those who relapse or fail to show early virological clearance.

在抗病毒治疗4周后HCV-RNA阴性的患者可能12周的抗病毒治疗即有效，对于复发或没有早期病毒学应答的患者可能需要更长疗程的治疗。

Positive signals of HPV antigen were distributed over cell plasm,and the distribution characteristic of positive signals related to differentiated degree of tumor cell.

近年来 ，人们对HPV与食管癌的关系进行了大量的研究，不同国家和地区食管癌组织有不同HPV感染率的报道，也有完全阴性的结果[1 ] 。

HIV-uninfected adults with noncavitary tuberculosis were treated daily with isoniazid, rifampin, pyrazinamide, and ethambutol for 2 months, followed by 2 months of isoniazid and rifampin. After 4 months, patients with drug-susceptible TB whose sputum cultures on solid media were negative after 8 weeks of treatment were randomly assigned to continue treatment for 2 more months or to stop treatment.

患有非空洞肺结核的HIV非感染成人患者每天采用异烟肼、利福平、吡嗪酰胺和乙胺丁醇进行治疗（共治疗2个月），其中采用异烟肼和利福平进行治疗的患者需要随访2个月。4个月后，存在药物易感性TB且治疗8周后固体培养基的痰培养为阴性的患者随机分为继续治疗2个月以上或停止治疗。

The construction of A83 eukarotic expression vector will play an important pole in researching the effect on HBeAg expression and disease mechanism when A83 mutation in HBV signal peptide reg

HBV A83点突变真核表达载体的构建为体外研究该点突变对HBeAg表达的影响以及HBeAg阴性的乙型肝炎病毒感染的致病机理奠定基础。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
