特异性

The combining examination of CA19-9 and CEA can elevate the specificity of diagnosis of gastro-intestinal cancer, and it has important value for both detecting the recrudesce of cancer and evaluating the treatment effect.

CA19-9和CEA联合检测可提高消化道恶性肿瘤诊断的特异性，对临床监测肿瘤的转移与复发以及疗效观察具有指导意义。

Compared with the gold standard of clinical diagnosis by a pediatric neurologist who had not seen the pictures,headache drawings depicting pounding pain, nausea or vomiting, recumbency, periorbital pain, photophobia, or visual scotoma had a sensitivity of 93.1%, a specificityof 82.7%, and a positive predictive value of 87.1% formigraine.

同未见过这些图画的儿科神经学医师用于临床诊断的黄金指标相比，描述出重击头痛、恶心或呕吐、斜卧、眼窝疼痛、畏光或视觉盲点的头痛图画，可预测偏头痛的灵敏度为93.1%，预测特异性为82.7%，阳性预测值为87.1%。

The specificity and precision is superior to other heating methods, it is a non-invasion treating method with reduplication.

磁诱导支架加温的特异性和确切性优于其他加温方法，是一种无创的、可重复的治疗手段。

The therapeutic effect of acupuncture may be caused by the extra-central reflex arc of the trigeminal nerve and cervical sympathetic nerve.

本课题研究结果为人中穴在缺血性脑血管病急性期治疗中的特异性作用提供了实验依据。

For targeted and regulable gene transcription, tissue or tumor specific promoters and some manual regulatory systems are used to regulate therapeutic gene expression.

为了实现基因的靶向可调控表达，组织或肿瘤特异性的启动子和人工合成的可调控表达系统被用来调控治疗基因的表达。

Reiter's syndrome is mostcommon in young men who have just recovered from non-specific urethritis.

瑞特氏症候群是最常见的在青年男子谁刚才已恢复从非特异性尿道炎。

As we know, SWI/SNF is a global, untargeted chromatin remodeler which influence transcription, it perform gene-specific regulation by interacting with some selective activators. On the other hand, no known DNA-binding domain is found in BEX1. So we come to a conclusion that BEX1 may mediate activators interact with hSNF5, and this result in the transcription of specific sets of genes that control the cell cycle.

由于BEX1本身并未发现能与DNA直接结合，而hSNF5所在的染色质重塑复合体单独存在时作用没有特异性，我们推测，BEX1可能作为接头分子，介导了其它蛋白与hSNF5的作用，导致控制细胞周期相关基因的转录激活或抑制。

Objective:Hepatocyte growth factor speculated to be an endothelial-specific growth factor which protects or repaire the vascular endothelial cells.

目的：肝细胞生长因子是一种特异性内皮生长因子，参与血管内皮损伤修复过程。

It proved that the establishment in our experimentation of indirect competitive ELISA has highly specificity, sensitivity, stability and repetitiveness. And it is fit for determining a big batch samples, and it is an effective method for determining the quantum of MT.

说明本试验建立的间接竞争型ELISA具有特异性强、灵敏度较高、稳定性和重复性好、适合于大批量样品的检测等优点，不失为对MT进行定量分析的一种有效方法。

The protein had the specificity on substrate recognition, which could decompose 3,4-dihydroxybenzoic acid to catechol but not 2,4-dihydroxy- benzoic acid to resorcin. The ligand at C-3 site of benzene ring had no effect on enzyme activity.

蛋白质还具有底物识别的特异性，能够催化3，4-二羟基苯甲酸转化为邻苯二酚，而不能催化2，4-二羟基苯甲酸转化为间苯二酚，这表明苯环上3'位的配基对酶活无影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
