选择80例接受开胸手术的病人，随机分为静脉镇痛组和神经冷冻组，静脉镇痛组行术后病人自控静脉镇痛，后者采用北京库蓝公司JT-1型冷冻治疗仪在关胸前对切口所在肋间及上、下各一肋间和放置胸引瓶所在肋间的肋间神经进行冷冻，以VAS评分判断两组术后胸部切口疼痛情况，并记录不良反应。

Through systematic study, it is found that the ion dose is another important parameter in Ion Beam Manipulation and it has significant influence on the strutrual phase transition. If the dose is precisely controlled, the structural phase transition could be traced under a quasi-continuous way. Consequently, many new phenomena have been discovered by Ion Beam Manipulation.

一、研究了离子束剂量在离子束操纵技术中的重要影响；研究表明离子束剂量可以精确地控制，使材料中的结构演变过程接近于连续地变化，因此可以对离子束诱导的结构相变进行准连续状态的跟踪，发现了许多新的现象。

A standard dose of interferon and ribavirin, but afterwards you can eventually re-treat them with a higher dose.

最后可以重新用更高的剂量治疗他们。这周我们在EASL会议上展示了来自我的研究小组的结果。

These are recommended dose rates for Sugar Refining and related decolorization applications but dose rates for other applications and filter types may vary.

当活性炭用于精制糖和糖液脱色时可按下列建议剂量使用硅藻土，用于其他场合时应根据过滤装置类型进行调整。

This paper dealed with the immunnodulation tests of white wax scale in specific and unspecific immunity. The result showed that the IgM in high dose group was clearly higher than that of the control in serolysin test. Lymphocyte transformation and propagation in mice were notable in high dose group.

对白蜡虫的特异性和非特异性免疫调节功能进行了试验研究，结果表明：特异性免疫的血清溶血素试验中，白蜡虫高剂量组小鼠的溶血素生成量明显高于对照，淋巴细胞转化增殖试验中，白蜡虫高剂量组小鼠的淋巴细胞转化增殖明显。

Results The inhibitive ratio to mouse ear edema was 12.27%,30.86% and 35.13% in low dose, middle dose, high

结果：1、珍芪滴眼液低剂量组对小鼠耳肿胀抑制率为12.27%，与阴性对照组相比无显

In the model of DNFB-induced mouse ear edema, the inhibitory rate of edema of compound A at dose of 50mg/kg/d p. o. was 41%, the inhibitory rate of myeloperoxidase activity was 81% of compound A at the same dose.

化合物A灌胃给药50mg／kg／天可抑制DNFB诱导的小鼠迟发型变态反应，耳肿胀抑制率为41%，耳髓过氧化物酶抑制率为81％。

Methods The drug is given to rhesus monkey by the intramuscular injection, first dose duplicate followed by a single dose at 24,48,72,and 96hrs for 5 days, the total doses are given respectively as 15.0mg/kg, 7.2mg/kg, 3.6mg/kg, 1.8mg/kg. Experimental animal was bitten by Anopheles dirus before giving drug, and at 6,12,24,30,36,48,54,60,72,84,and 108hs later, mosquites were examined for oocysts on day 9 and sporozoites on day 13 after infection.

方法首剂药量加倍，随后24，48，72和96小时给实验猴各肌注一次，疗程5天，总剂量分别为15.0mg/kg、7.2mg/kg、3.6mg/kg、1.8mg/kg；在给药前及给药后6、12、24、30、36、48、54、60、72、84和108小时各用一批大劣按蚊叮咬实验猴，叮咬后第9天解剖蚊胃，第13天解剖涎腺。

The dose-dependent experiment revealed that Id1 antagonised E47 and Ets1 mediated transcriptional activation in a dose-dependent manner. With pGL3-870 as a template, site-directed mutagenesis of E-box and / or ETS-binding site was introduced into p16 promoter. E47 could not activate the transcription of p16 promoter with E-boxes mutated, and Ets1 could not activate the transcription of p16 promoter with EBS mutated. The synergy effect between E47 and Ets1 would occur only if the E-boxes and EBS were present. These facts demonstrated that E47 and Ets1 proteins were not recruited to the promoter by binding to other cis-elements or through interaction with other protein factors, however, they bound to DNA directly through respective consensus sequences in p16 promoter.

以pGL3-870为模板，构建了E-box或/和EBS点突变的p16启动子报告基因载体，将野生型和突变型的报告载体分别与pI-E47、pI-Etsl以及pI-E47+pI-Ets1共转染，发现E47和Ets1所诱导的转录激活作用依赖于启动子DNA上存在的各自的特异结合序列，二者的协同作用也只有当两个结合位点都存在时才会发生，说明E47和Ets1不是与其它作用元件或其它蛋白质因子相作用而被招募到该启动子的，它们是通过启动子上各自的特异结合位点与DNA直接结合的。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.
