血清阴性

The data suggest that the patients with serologically negative non A～E hepatitis have a different etiology and should be tested by PCR to identify the disease.

Objective:To investigate the epidemiologic and clinical features of seronegative liver diseases and guide diagnosis and treatment.

目的：探讨肝炎病毒血清学标志阴性肝病患者流行病学和临床特点，指导临床诊断和治疗。

Objective The study was designed to investigate whether there existed provirus HIV DNA in the liver tissues of intravenous drug users with seronegative results of anti-HIV test.

目的 了解血清抗-HIV阴性的静脉药瘾者肝组织是否存在前病毒HIV DNA。

Compared with seronegative patients, the adjusted hazard ratio for development of clinically definite multiple sclerosis was 76.5 (95% confidence interval , 20.6 - 284.6) for patients with both antimyelin antibodies, and 31.6 (95% CI, 9.5 - 104.5) among patients with only anti-MOG.

与血清呈阴性的患者相较之下，对於含有二种抗髓磷脂抗体的患者而言，经调整的临床上多重硬化症发展的风险比率为 76.5（95%信赖区间，20.6-284.6），只有抗MOG抗体的患者为31.6（95% CI，9.5-104.5）。

The differential expression protein with MALDITOFTOF by means of mass spectrographic was analyzed.

结果 重复性好的双向电泳图谱在CA 125阴性卵巢上皮性恶性肿瘤患者血清蛋白质表达谱发生了改变。

AFA was correlated to other autoantibodies of RA. Immunoblotting detecting of AFA, a simple and standardizable test, may be an alternative or complement to conventional detection of RF, APF, anti-CCP and AKA, suit to apply in clinic.

结论AFA 可视为RA 的特异性血清学标记，尤其对RF 阴性以及早期RA 诊断很有帮助；AFA 与其它RA 相关自身抗体相关，他们联合检测可以相互补充，提高对RA 的诊断价值； AFA 检测方法简单可靠，适合在临床上应用推广。

Compared with young and older adult groups,0～14 years-old group showed higher TIgE leve...

结论血清TIgE测定不能有效地排除有过敏症状患者对常见吸入性过敏原是否过敏；但高TIgE水平可增加过敏的概率，源于正常人群的TIgE参考值不能用来区分过敏试验阳性和阴性的患者，因为二者有广泛交叉。

Test of NO, TNFa, LPS in the serum and ascites of the patients with liver cirrhosis ascites can contribute to distinguishing between exudative ascites and transudate ascites and distinguishing between spontaneity peritonitis is infected in Gram-positivebacteria and Gram-negative-bacteria so as to instruct clinical use of drugs.

肝硬化腹水患者血清及腹水中测定NO、TNFa、LPS，有助於鉴别渗出性腹水和漏出性腹水；有助於鉴别自发性腹膜炎是革兰阴性菌或革兰阳性菌感染引起，指导临床用药。

MethodsACCP antibody and RF were detected in serum samples of 90 RA patients, 30 other diseases patients and 35 healthy blood donors.The sensitivity,specificity,positive predictive value, negative predictive value, agreement rate and Youden's index of these parsmeters for the diangnosis of RA were analyzed.

方法对90例RA患者、30例其他疾病患者和35例健康对照组血清用ELISA法检测抗CCP抗体、免疫散射比浊法检测RF，比较2种抗体单独或联合检测对诊断RA的敏感性、特异性、阳性预测值、阴性预测值、总符合率及Youden指数；探讨抗CCP抗体和RF的相关性，通过绘制ROC曲线，计算ROC曲线下面积。

The destructive effect on HBsAg in serum was potentiated when chlorhexidine was added to the ethanol.

试验用正常人血清，取自献血员，肝炎标志物均为阴性。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。
