Analogously, parameters of sub-cluster of Chinese herbs are obtained.

本文通过群子统计参数，分析了现今抗艾滋病的高频中药，其结果表明这些高频药有两类：一是有抗艾滋病病毒的阴性药；二是提高免疫力的阳性药；继而从分析中得出特殊单味药的规律，即r：和rZ均大的中药，具有良好的抗艾滋病功能。

Results:The positive rates of TSP- 1 mRNA in hypertrophic scars and keloid were lower than those in normal skin and surgical scar. MVC was higher in the cases with negative expression of TSP - 1 mRNA than the ones with positive expression of TSP - 1 mRNA. MVC was higher in the hyperstrophic scar and keloid than in normal skin and surgical scar.

结果TSP-1 mRNA在增生性瘢痕和瘢痕疙瘩中表达的阳性率低于在正常皮肤和外科瘢痕组织中的表达(P＜0.05)；TSP-1 mRNA表达阴性病例组的MVC显著高于TSP-1 mRNA阳性病例组的MCV(P＜0.05)；增生性瘢痕和瘢痕疙瘩组织中微血管数多于正常皮肤和外科瘢痕组织的微血管。

The results showed that the 56kD and 26kD antigens had better immunogenicity and could not react with the sheep positive serum of Mycoplasma pneumonia and negative serum of E. ovis. Of the 64 samples detected, the positive rate was 66.7%(42/64), 22.9% higher than that of direct microscopic examinerion.

结果表明，56kDa和26kDa的羊附红细胞体抗原具有较好的免疫性，而且不与羊附红细胞体阴性血清和羊支原体病阳性血清发生交叉反应，具有较好的特异性；ELISA检测的64份血清样本的阳性率为66.7%，比涂片镜检高22.9个百分点。

When Shigella flexneri 2a 2457T is cultured at 30℃, it's phenotypically avirulent; when grown at 37℃, its virulence improves greately. There is clear evidence that the temperature-dependent expression of the virulence genes is controlled by H-NS protein.

痢疾杆菌在30℃时不具有侵袭力，37℃时毒力明显增强，已有的研究表明这种依赖于温度的毒力基因的表达受H-NS蛋白的调控。H-NS是一种重要的类核相关蛋白，在革兰氏阴性菌中普遍存在，能够调控大量基因的表达。

Repelled by light;exhibiting a negative phototactic or phototropic response .

避光的，怕光的被光排斥的；表现为阴性趋光的或趋光反应的

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。

All ending in N, P, S, or in the two compounds of this last, PS and X, are masculines. All ending in the invariably long vowels, H and O, and in A among the vowels that may be long, are feminines.

所有以N、P、S结尾的，或者与S组合的PS、KS结尾为阳性，所有以不变的长元音、H、O以及可以作为长元音的A结尾的为阴性。

A point on the Primum Mobile (the Zodiac for practical purposes) which, in the horoscope of an individual, is occupied by a certain planet, manifests its influence depending on the properties of this planet, and acts on the individual as long as he lives.

在个人星盘上，星体所座落的黄道位置以及该星体天性间所产生的交互作用会影响命主一辈子。例如火星金牛的作用方式，是火星的天性，加上金牛的阴性固定土象所共同组成。

China is making intense preparations to ensure that the Olympics showcase its brightest achievements. Ensuring enough Rh-negative blood is just the latest attempt to avoid mishaps over health and food safety that would tarnish its image during the games.

中国正在紧锣密鼓的作准备，确保奥运会展示中国最耀眼的成就，确保拥有足够的Rh阴性血不过是当局的最新努力，当局要避免在保健和食品安全方面发生事故，这类事故一旦在奥运期间发生将损害中国的形像。

Several years ago, Lorenza Lazzari, of the Maggiore Foundation Hospital in Milan, Italy, and her colleagues detected low levels of Oct4 expression in adult stem cells, but their negative controls, which did not contain stem cells, yielded the same result.

早在几年前，意大利米兰的Maggiore基金会医院的Lorenza Lazzari及她的同事就发现，成熟干细胞中Oct4蛋白的表达水平低，但是不含干细胞的阴性对照也有相同结果。

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。
