Methods The expression of HIF-1α was assayed by means of immunohistochemical technique in 60 patients.

方法通过免疫组织化学方法，了解HIF-1α在60例原发性颊黏膜鳞癌中的表达，分析其阳性表达水平与颊癌临床分期、病理分级以及预后等临床病理因素之间的关系。

Their six generations F1, F2, backcrosses B1 and B2 and their parents P1 and P2 were used to study the inheritance of eggplant fruit color traits with joint analysis of multiple generations.

以3个果色不同的茄子栽培种自交系为试验材料，用色差仪和目测相结合的方法将果色分级，通过P1、P2、F1、B1、B2和F26个世代联合分析法，研究茄子果色性状的遗传规律。

Methods Fifty-nine patients with lupus nephritis (12 in World Health Organization class III, 46 in class IV, and 1 in class Vb) received induction therapy consisting of a maximum of seven monthly boluses of intravenous cyclophosphamide (0.5 to 1.0 g per square meter of body-surface area) plus corticosteroids.

我们假设评估 COPD 呼吸系统表现和全身表现的多维分级系统能更好地对这些病人进行分类，并预测这些病人的转归。

In the event of the organizer losing a brevet card, no replacement to the rider will be made.These brevets are not competitive events, so no rider classifications are made. Commemorative medals for each brevet are available for purchase. Those wishing to purchase a medal should mark their brevet card accordingly. Payment is required at the finish.

若不幸大会在检查过程中遗失挑战者的卡片，将不补发所有的资格赛活动都不是竞赛活动，所以大会不将所有参赛的挑战者分级，挑战者可以自由购买每次的活动纪念奖牌作为留念，购买的挑战者必须要在卡上注记，并在比赛结束时缴费。

Flat Toby also has been to pre-kindergarten graduation, an uncle's 50th birthday party in Cheyenne, Wyo., and a Denver Broncos game, although he sat in the car because it was raining.

这个平面版的托比参加了幼儿园学龄前的分级事务和一位叔叔在夏延举行的50岁生日宴会。

Methods 6 cases of COPD with giant bullae were treated by video-assisted thoracoscopic surgery and a small incision. Before the operation, the patient's dyspnea were graded by Hugh-Jones: 2 cases were class Ⅱ, 4 cases were class Ⅲ.

采用胸腔镜辅助小切口手术治疗COPD合并巨大肺大疱6例，患者术前Hugh-Jones呼吸困难分级：Ⅱ级2例，Ⅲ级4例。

On the scion experiment: the following were studied mainly: the time of scion collecting, classification of scions by quality, influences of environmental factors such as temperature, humidity on scion storage and the callusing ability of scions, and so on.

在接穗方面，主要研究了接穗采集时期、接穗质量分级、接穗贮存条件、接穗愈伤能力等。

They were divided into two groups:elderly group(with 3 or more centrums hyperosteogeny) and younger group(with less than 3 centrums hyperosteogeny). Then they were evaluated according to Meyerding method and analyzed by χ2 and Fisher accurate probability examination.Results Among the younger group,any degree of lumbar spondylo-listhesis had all prominent relationship with spondylolysis.

方法回顾2002年以来笔者所在医院放射科腰椎滑脱患者316例，对腰椎滑脱采用Meyerding法分级，把腰椎滑脱的患者分为老龄组(腰椎同时有3个以上椎体骨质增生)及青年组(腰椎未见骨质增生或有1～2个椎体骨质增生)，同时，在不同年龄组中对不同程度腰椎滑脱患者分组并利用SPSS13.0进行χ2和Fisher精确概率检验分析，得出结论。

Results ①p53 positive expression rate in cervical carcinomas 85.71%( 30 /35) was significantly higher than that in normal cervixes 6.67%( 2 /30),P= 0.001.②p53 expression is correlated with the differentiation state and pathologic grades.The positive expression rate of p53 in the cervical carcinomas of grades Ⅰ 57.14%(8 /14) was significantly lower than that in the cervical carcinomas of grades Ⅱ 86.67%(13 /15) and grades Ⅲ 100.0%(6 /6),P＜0.05.③The positive rate of PCNA in the cervical carcinoma of grade Ⅰ 64.29% was signifi cantly lower than that in the grade Ⅱ 93.33% and grade Ⅲ 100.0%,P＜0.05.Conclusion Our data indicate that the alteration of p53 is involved in cervical carcinoma.

结果 ①P53蛋白在宫颈癌组织中的表达率为85.71%(30 /35)，明显高于在正常宫颈组织中的表达率6.67%( 2 /30)，P = 0.001；②P53蛋白阳性表达率与宫颈癌组织的病理学分级有关，P53在宫颈癌Ⅰ级中的阳性表达率57.14%（8 /14）明显低于Ⅱ级86.67%（13/15 和Ⅲ级100.0%(6/6)，P＜0.05；③宫颈癌组织PCNA阳性表达率Ⅰ级64.29％明显低于Ⅱ级93.33％和Ⅲ级100.0%，P＜0.05。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
