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。

Eighty volunteers, half of whom were seronegative for herpes and the other half were seropositive received either the GD2T with an immunostimulant or the immunostimulant alone.

80志愿者，其中一半是阴性的疱疹，而另一半是不是收到阳性与免疫增强剂或免疫增强剂单独的

Results The level of AAG,AAT,HPT and CER in patients with RA and seronegative spondyloarthropathy and all kinds of arthritis was significantly higher than that in normal controls (P＜0.001) and was positively correlated with that of ESR and CRP.

结果 RA、血清阴性脊柱关节病及关节炎综合组患者该4项指标浓度均显著高于正常对照组(P＜0.001)。并与血沉、C-反应蛋白呈正相关。

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）。

Objective To explore the concentration changes of the serum acute-phase proteins,including α1-acid glycoprotein,α1-antitrypsin,haptoglobinand cernloplamin in patients with rheumatoid arthritis and seronegative spondyloarthropathy in active stage and their clinical significance.

目的 观察活动期类风湿性关节炎和血清阴性脊柱关节病患者血清4种急性时相反应蛋白α1-酸性糖蛋白、α1-抗胰蛋白酶、触珠蛋白和铜蓝蛋白浓度的变化及其临床意义。

The dose-response relationship was most prominent for participants who were seronegative for HBeAg with normal serum ALT levels and no liver cirrhosis at study entry.

血液中B型肝炎病毒量与肝癌风险的剂量效应关系在e抗原阴性、血中丙胺酸转胺脢正常且进入研究时无肝硬化的个案最为显著。

The frequency of CMV seronegativity showed a stepwise decrease with the increase of donor age. In addition, the prevalence of HBsAg, antibodies to hepatitis C virus, antibodies to human immunodeficiency viruses type 1 and 2 (anti-HIV 1+2) and antibodies to human T-cell lymphotropic viruses type I and II (anti-HTLV 1/11) were compared between CMV seropositive and seronegative groups. Our results showed that there was no significant difference in seroprevalence of these markers between CMV seropositive and seronegative groups.

为了更进一步了解巨细胞病毒抗体和其它血液筛检项目之相关性，吾人在同批检体中比较巨细胞病毒抗体阳性者和阴性者其 B 型肝炎表面抗原、C型肝炎抗礼、第一型暨第二型人类免疫缺乏病毒抗体和第一型暨第二型人类嗜 T 淋巴球病毒抗体之阳性率，结果发现这些阳性率在两者间无有意义之差异。

Results Compared with percutaneous coronary angiography,the sensitivity of sixteen slice sparil CT in diagnosing moderate and severe coronary stenosis was 83.33%,and the specificness,positive predictive value,negative predictive value and degree of accuracy was 91.40%,85.59%,89.95% and 83.33% respectively.

计算 出16层螺旋CT冠状动脉成像对冠状动脉狭窄的诊断准确性指标。结果 16层螺旋CT冠状动脉造影对照经皮选择性冠状动脉造影对冠状动脉中、重度狭窄显示的对照结果：敏感性83.33%、特异性91.40%、阳性预测值85.59%、阴性预测值89.95%、准确度83.33%。

Results Compared with percutaneous coronary angiography,the sensitivity of sixteen slice sparil CT in diagnosing moderate and severe coronary stenosis was 83.05%,and the specificness,positive predictive value,negative predictive value and degree of accuracy was 95.97%,89.09%,93.46% and 92.31% respectively.

结果 16层螺旋CT冠状动脉造影对照经皮选择性冠状动脉造影对冠状动脉中、重度狭窄显示的对照结果：敏感性83.05%、特异性95.97%、阳性预测值89.09%、阴性预测值93.46%、准确度92.31%。结论 16层螺旋CT冠状动脉造影对心电图正常的胸痛患者具有良好的诊断价值，并可对冠状动脉形态学进行良好的评价，从而进行介入治疗的筛选。
