战金辉，李吉来，黄旭日*，左明辉，孙家锺摘要：采用遗传算法构建了27种人类腺苷受体拮抗剂1，2，4-三唑并[1，5-α]喹喔啉衍生物与受体之间的亲和性的QSAR模型。

ABSTRACT In many flowering plants, self-incompatibility is a genetic mechanism to prevent self-fertilization and, in most cases, is controlled by a single multiallelic S locus.

自交不亲和性(self-incompatibility，SI)是高等植物特有的一种自我识别机制，它可以防止近亲繁殖，增加遗传变异。

Self-incompatibility (self-sterility) The condition in whereby male gametes cannot fertilize female gametes from the same individual and give rise to a viable embryo.

自交不亲和性：是雄配子体不能与来自同一植物体的雌配子体发生受精作用并产生可育受精卵的情况。

AIM: To study the affinity with tumor cells through series of N-octyl-N'-succinyl chitosan synthesized by using different molecular weight of chitosan.

目的：以不同分子质量的壳聚糖为原料合成系列的N－正辛基－N'-琥珀酰基壳聚糖，考察其与肿瘤细胞的亲和性，为其作为抗肿瘤药物的靶向载体提供依据。

RESULTS: N-octyl-N'-succinyl chitosan possessed stronger affinity than control cell lines and growth inhibition with the four kinds of tumor cells.

结果：N-正辛基－N'-琥珀酰基壳聚糖对4种肿瘤细胞亲和性明显强于空白细胞株(P.01)，并具有一定的肿瘤抑制作用。

METHODS: A series of N-octyl-N'-succinyl chitosan labeled with fluorescein, were incubated with HepG2 liver cancer cells, K562 leukemia cells, A549 human lung cancer cells, and BGC cancer cells respectively and followed by using flow cytometry and enzyme-linked immunosorbent assay to assess the affinity and inhibition of N-octyl-N'-succinyl chitosan for the four kinds of tumor cells already mentioned.

用异硫氰酸荧光素对N-正辛基－N'-琥珀酰基壳聚糖进行标记，再分别与人肝癌细胞(HepG2)、人白血病细胞(K562)、人非小细胞肺癌细胞(A549)及人胃癌细胞共培养，通过流式细胞仪及酶联免疫检测仪测定N-正辛基－N'-琥珀酰基壳聚糖对肿瘤细胞的亲和性及抑制力。

Cells on a biomaterial surface usually respond to three main categories of physicochemical cues: chemically, topographically, and mechanically. In this study, mechanical property of a particularly-prepared chitosan film was modified to improve its cell affinity.

而细胞受生物基材表面的物理化学讯号影响，主要可分为三类：化学、形貌和机械性质，本研究以修饰特别制备的几丁聚醣膜表面性质来改善细胞亲和性。

Results of investigation in the inheritance of self-incompatibility of turnip were reported in the paper.

本文详细报告了作者对芜菁自交不亲和性若干遗传特性的遗传研究结果。

PNAs are uncharged DNA mimics, which are resistant to nucleases and peptidases, and hybridize with complementary DNA and RNA with high affinity.

PNA是一类不带电荷的DNA相似物，不受核酸酶和肽酶的作用，可以和cDNA、RNA高亲和性杂交。
