There were simple decompression as group A, internal neurolysis after decompression as group B, lemithason(0.5 mg/kg) injected in the epineurium after decompression as group C, and lemithason(0.5 mg/kg) injected around the epineurium after decompression and internal neurolysis as group D.

在大鼠坐骨神经卡压模型基础上，将60只SD成年雄性大鼠随机等分为四组。A组：仅去除卡压；B组：去除卡压后切开神经外膜；C组：去除卡压后神经外膜下周围注射利美达松(0.5mg/kg)；D组：去除卡压后切开神经外膜，然后在神经周围注射利美达松(0.5mg/kg)。

The patients were divided into four groups. Group A included 48 women with previous unilateral salpingectomy. Group B included 41 patients with previous bilateral salpingectomy. Group C included 50 patients with obstruction of fallopian tube while group D included 40 patients with hydrosalpinx (without surgical procedure before). The ovarian responses to superovulation and the outcomes of IVF-ET were evaluated.

选择2006年2月至2007年6月在本中心行常规IVF-ET治疗的179例不孕患者为研究对象，共分为A、B、C、D四组，A组为48例单侧输卵管切除患者，B组为41例双侧输卵管切除患者，对照C组为50例双侧输卵管阻塞患者，对照D组为40例单侧或双侧输卵管积水患者，比较4组患者在IVF-ET周期中卵巢对控制性超排卵的反应及其结局的差异。

Administration of methotrexate to rats caused severe enterocolitis with 66. 7% and 16. 7% mortality within 72 hours in the first group and the second group (2% Gln), respectively. But the sucrase and aminopeptidase activities, protein content, DNA and RNA content of small intestine in rats of group 3 and group 4 were significantly higher than those in rats of group 1 and group 2. These meant that GEON enhanced digestion processes, so it can be used to improve nutritive conditions of the small intestine.

用氨甲蝶呤诱发小肠炎后，分别饲喂Gln含量不等的氨基酸营养液，实验结果表明，氨甲蝶呤诱发的小肠炎是一种较严重的应激状态，在72小时内，零剂量组大鼠的死亡率高达66.7％，2％Gln组的死亡率为16.7％，其它测定指标也相对较低，说明对小肠炎模型而言，营养液中2％的Gln含量可能偏低，第三组和第四组（结晶氨基酸组，Gln含量同第三组）的死亡率为零，体重有所恢复，蔗糖酶活、氨肽酶活、DNA和RNA含量增加，这说明，Gln活性肽营养液对小肠炎具有一定的治疗作用，可作为小肠损伤后的辅助治疗药物。

The parameters of perfusion signal intensity-time curve, including upslope、peak signal intensity, and time to peak signal intensity were analyzed for each segment in different groups.

依据冠状动脉造影结果将不同狭窄程度血管所供心肌节段分为四组，即明显狭窄组(血管狭窄≥75％)、中度狭窄组(血管狭窄在50％～74％)、轻度狭窄组(血管狭窄＜50％)及正常组，分析每一节段心肌灌注信号曲线参数(最大斜率、强化峰值及达峰值的通过时间)并比较组间差异。

Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.

取SD雄性大鼠24只随机分成对照组、PCA组、LPS组和LPS+PCA组四组，对照组尾静脉注射生理盐水，PCA组尾静脉注射蝮蛇毒蛋白C激活物，LPS组腹腔注射LPS (10 mg/kg， 4h)的方法建立败血症休克的实验动物模型，在建立败血症的实验动物模型的基础上，尾静脉注射PCA (0.4 mg/kg)为LPS+PCA组，每只大鼠均于药后30 min时运用Medlab生物信号采集处理系统记录平均动脉压和左心室功能指标，并测定心肌中乳酸脱氢酶活性、诱导性一氧化氮合酶活性及心肌病理切片。

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。
