放射敏感性

This study implied that radiation-induced chromatid/isochromatid breaks can be possibly used as a good predictor of radiosensitivity of hepatoma cells,also it could be used to design radiotherapy schedule for liver can-cer patients.

辐射诱导的染色单体断裂是预测肝癌细胞内在辐射敏感性的一个良好指标，可为肝癌的临床放射治疗计划提供依据。

The results showed that LRK could significantly inhibit the mammary hyperplasia caused by estrin, reduce the content of serum 〓, raise P level, promote the production of DA in hypothalamus and mammary tissue, decrease the release of 5-HT, inhibit the secretion of serum PRL, reduce the sensitivity of mammary tissue to estrin and progestogen, prevent the expression of mammary tissue on PCNA, the effect was equal to triphenylamine oxide, obviously superior to the control group of Ru Zeng Ning.

通过实验研究，建立了具有肾虚肝郁证侯群的乳腺增生病理模型，利用免疫组化技术、图像分析系统、荧光分光光度法、放射免疫法等现代医学研究方法，从病理形态学、医用体视学、神经内分泌学、阴道细胞学等方面，观察了利乳康口服液对模型动物整体状态、乳腺组织病理形态、血清激素、神经递质以及卵巢功能的影响，结果表明利乳康口服液能明显抑制雌激素引起的乳腺组织增生，降低血清E〓含量，升高P水平，促进下丘脑及乳腺组织中DA的产生，减少5-HT释放，抑制血清PRL分泌，降低乳腺组织对雌、孕激素的敏感性，阻止乳腺组织PCNA的表达，其效应与三苯氧胺相当，明显优于乳增宁对照组；另外，利乳康口服液还能缓解模型动物肾虚肝郁证侯群，增加其体重，调节其整体状况，改善模型动物不规则动情周期，减轻其子宫及卵巢的病变，抑制子宫内膜的过度增长，调节卵巢功能，揭示了中药利乳康口服液对神经内分泌和卵巢功能的整体调控作用，以及对本病发生、发展的预防作用

In this article, the radiosensitization and development of radiotherapeutic technology are reviewed. Recent progress in reducing the radiation-induced hepatic injury is also summarized.

本文主要从肝癌放疗敏感性、放疗技术的发展等方面对PHC的放射治疗作一综述，旨在说明PHC的放射治疗在减少放射性肝损伤等方以取得了可喜的成绩，且仍有较大发展空间。

In this study, decreasing the expression of RB in human breast cancer cells made the cells unresponsie to tamoxifen.

相反的，人乳癌细胞RB表达下降增加了细胞对放射和其他抗癌药的敏感性。

Treatment interruption longer than 1 weeks did not take place.Conclusions Concurrent chemoradiotherapy is preferable for local advanced NSCLC. VIL can enhance the radiosensitivity of NSCLC. Cinical activity of the single agent vinorelbine as radiosensitizer can be continued.

本研究采用剂量的VIL用于同步放射治疗局部晚期NSCLC总有效率和完全缓解率优于单纯放射治疗，毒副反应可以耐受，提示VIL可以明显增加NSCLC放疗的敏感性，为临床NSCLC的合理治疗提供了理论依据。

PCNA was positively significantly correlated with p53 gene expression both in the treatment group and contr...

作者认为，PCNA和p53基因的表达可作为脑胶质瘤对放射敏感性和恶性程度的标志之一。

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。
