Results Lorcainide at concentration of 0.62mg/L,1.25mg/L and 2.50mg/L had a tendency of decreasing the incidence of arrhythmia during ischemia (P＞0.05),and at 1.25mg/L and 2.50mg/L significantly decreased incidence of arrhythmia during early reperfusion (P＜0.05).Its antiarrhythmic effect was accompanied with elevation of subendocardial threshold,significant abbreviation of action potential duratin in subendocardium and subepicardium,and complete or partly delay of transmural conduction time of pulses.

结果 劳卡胺分别在0.62mg/L、1.25mg/L及2.50mg/L剂量时使缺血性心律失常发生率轻度降低(P＞0.05)，后2种剂量使再灌注早期心律失常发生率明显降低(P＜0.05)；降低心律失常发生率同时可提高心内膜下心室肌兴奋阈，延长心内、外膜下心室肌细胞动作电位时程，延迟或部分延迟冲动跨壁传导时间。

PCNA-labeled cells were first detected in subgranular zone of dentate gyrus 3 days after reperfusion, and increased with time.

再灌流3 d，增殖性细胞核抗原阳性细胞开始出现于海马齿状回的颗粒下层，并随再灌流时间延长，增殖性细胞核抗原阳性细胞数量增多。

Retinal neovascularizationincreasingly extended with the time of RRD,and developed into vitreousand subretinal space,no iris neovascularization was seen.

随着脱离时间的延长，新生血管范围逐渐扩大并长入玻璃体和视网膜下腔，未见虹膜新生血管。

渗氮＋渗硫复合处理可使渗硫层的持续时间显著延长，并能在各种速度条件下非常明显地提高表面的抗擦伤性能。

Methods After taking triazolam and distilled water respectively, the mice sleeping-behavior state was observed and recorded; the ratio of sleeping mice was recorded after taking different of ingredients Eucommia ulmoides Oliv. combining with pentobarbital sodium at subliminal dose, and mice latent period and sleeping time at supraliminal dose. Measure the content of interleukin-1β(IL-1β) in mice brain with enzyme-linked immunosorbent assay, weigh spleen and thymus of mice.

通过观察记录日间小鼠睡眠行为状态，戊巴比妥钠阈下催眠剂量实验，延长戊巴比妥钠睡眠时间实验，酶联免疫吸附反应分别检测服用3种不同极性的提取部位、阳性对照物和空白对照组的小鼠脑组织中IL-1β含量，并结合脏器指数等综合分析。

To study the activation mode of LFA-1 on the NK cell surfuse, a platform based on optical tweezers was constructed to observe the molecular behavior of LFA-1. According to the results, the adhesion force between an NK cell and a polystyrene microsphere coated with anti-LFA-1 antibody was confirmed to be time-dependent.

我们利用光镊研究了NK细胞表面LAF-1的单分子行为，发现NK细胞与包被了LFA-1抗体的小球之间的结合力随二者接触时间的延长而增强，表明NK细胞表面LFA-1分子可能会受LFA-1抗体影响而发生局部聚集。

Chinese medicine has a long history of handling cancer,in recent years particularly,has produced satisfying results in such fields as attenuation and synergia for chemo,post-operation convalescence,reducing recurrence or metastasis,and improving survival time also quality of life.

中医治疗肿瘤历史悠久，特别是近年来的广泛深入研究，取得了相当大的成就，如在放化疗中的减毒增效作用，手术后的康复和降低复发转移，晚期患者的改善生活质量、延长生存时间等方面都得到了认可。但也还存在一定问题。
