The positive rates of pcna of every 100 cells on vh , vc and scc were 7 . 85 1 . 52 , 13 . 83 1 . 69 and 29 . 46 2 . 03 , respectively , presenting significant differences 增殖细胞核抗原之每一百个细胞之细胞阳性率在口腔上皮增生、疣状癌及鳞状细胞癌分别为7 . 85 1 . 52 ， 13 . 83 1 . 69及29 . 46 2 . 03 ，亦呈现有意义的差别。
Nr was found in 6 of 22 cases of renal tissues adjacent to nephroblastoma whereas it was found in only 1 of the 30 cases of non - neoplastic mature renal tissues 方法在光学显微镜下比较30例肾母细胞瘤和16例不同胎龄肾组织的形态特点；观察比较22例肾母细胞瘤瘤旁肾组织和30例非肿瘤成熟肾组织中肾源性剩余的阳性率。
Objective : to provide a minimum sample size approach and a sequential sampling approach for testing whether the sporozoite rate has exceeded the critical level of malaria epidemics using the pool sampling method 摘要目的：给出基于混合样本的最小检测次数法和序贯检验法，以检验子孢子阳性率是否超过导致疟疾流行的临界水平。
It is found that the immobilization approach by polyelectrolyte absorbing takes more obvious advantages over that by glutaraldehyde binding . furthermore , the sealing method applied can reduce the false - infected rate perfectly 实验发现，聚电解质静电吸附固定法明显优于戊二醛共价键合固定法；此外，所采用的封闭方法能较好地克服测定的假阳性率。
Our country detects the person offer blood with 65 individual unusual transaminase makes clear , rate of positive of antibody of its third liver is 90 . 8 % ( 59 / 65 ) , the person that explain our country offers blood is crowd of third liver tall danger 我国检测65例单项转氨酶异常的供血者表明，其丙肝抗体阳性率为90 . 8 % ( 59 / 65 ) ，说明我国供血者是丙肝高危人群。
This positive predictive value of 78 . 5 % leads the researchers to estimate that if 5 patients with multinodular goiter exhibited the delayed washout pattern on dce - mri , 4 will probably have malignant lesions in the thyroid gland 通过78 . 5的阳性率使研究者们声称，如果5位多发甲状腺节结具有造影增强的延后消退的影像，那么其中的4位在甲状腺中有恶性的病理变化。
Methods impedance pneumoplethysmogram ( ipg ) and impedance respirogram ( irg ) were detected in 64 cases of patients with phd , and investigate dmf rheogram positive rate , also analysed various parameters of ipg in positive and negative groups 方法对64例肺心病患者进行呼吸阻抗图和肺阻抗图检测，分组统计膈肌疲劳图形阳性率；并对阳性组和阴性组进行肺阻抗图各参数比较。
Objective : to explore the safety of using diagnostic hysteroscopy in patients with clinical stage one endometrial cancer , whether diagnostic hysteroscopy can increases the risk of positive peritoneal cytology in such patients and affects their post - operative prognosis 摘要目的：探讨临床期子宫内膜癌患者使用诊断性宫腔镜的安全性，是否增加腹水细胞学的阳性率及对预后的影响。
Using a stringent objectie statistical algorithm to reduce false discoery rates below 5 % , we isolated a panel of 87 genes that represent major focal points of the autonomous response of cancer cells to the abrogation of microtubule dynamics 用严格客观的统计表格减少假阳性率至5 %以下，我们对一组87个基因（代表着肿瘤细胞自主反应的主要局部位点）进行分离到无微小管动力学存在的水平。
Result : in the 39 colorectal carcinomas , 35 ( 89 . 7 ) had detectable telomerase activity , in 21 ulcerative colitis , 2 ( 9 . 5 % ) had detectable telomerase activity and 22 normal colorectal mucosae the telomerase activity was not detectable 结果： 39例大肠癌阳性率为89 . 7 % ， 21例溃疡性结肠炎阳性率为9 . 5 % ， 22例正常对照组阳性率为0 % ，大肠癌端粒酶活性阳性率与肿瘤临床病理分期、组织学类型、肿瘤大小及部位无显著相关。
