Objective To explore livin, MTA1 and the caspase3 protein expression, their correlation and clinical pathology in colon cancer Methods The expressions of livin, MTA1 and caspase3 protein in 88 cases of colon cancer were detected by immunohistochemistry stainingResults Livin, caspase3 protein and MTA1 positive expression rates in colon cancer tissues were more than those in tissues beside the cancer Furthermore there were obvious relevance between livin protein, MTA1 positive expression rate and degree of histodifferentiation and lymph node metabasis and between caspase3 protein positive expression rate and degree of histodifferentiation of colon cancer Caspase3 protein expression had prominent inverse correlation with the livin expressionConclusions ①Over expression of livin having inhibtion on colon cancer is one of important factors of colon carcinogenesis ②Caspase3 protein expression in colon cancer tissues is inhibited to less and has prominent inverse correlation with livin expression Accordingly, suppressing caspase3 protein activity is one of channels, by which livin promotes colon carcinogenesis ③MTA1 plays the important role in histodifferentiation degree and lymph node metastasis of colon cancer

采用免疫组织化学染色方法检测88例结肠癌组织中Livin，Caspase3 及MTA1的表达情况。结果（1）结肠癌组织中Livin的阳性表达率显著高于癌旁组织，且Livin的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（2）结肠癌组织中Caspase3蛋白的阳性表达率显著高于癌旁组织，且Caspase3蛋白的表达与结肠癌的组织分化程度显著相关。（3）结肠癌组织中MTA1的阳性表达率显著高于癌旁组织，且MTA1的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（4）Caspase3蛋白的表达又与Livin的表达呈显著负相关。结论（1）Livin在结肠癌组织中过表达，它可能是促进结肠癌发生的重要因素之一。（2）Caspase3蛋白在结肠癌组织中表达被抑制而降低，且与Livin的表达呈负相关。因此，抑制Caspase3蛋白的活性是Livin促进结肠癌发生的途径之一。（3）MTA1对结肠癌的组织分化及淋巴转移发挥重要作用。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。

Results showed that the root colonization rate of S. gracilis (62.2%) was higher than that of A. conyzoides (36.5%) and P.notatum (37.3%).The arbuscule percentage showed a similar pattern. Although the biomass and P content in the shoots of the three grass species were comparable, P content in S. gracilis roots was higher than that in A. conyzoides and P. notatum roots. The species richness and hyphal density in the rhizosphere soil of S. gracilis plants were less than those of A. conyzoides and P. notatum plants, while the spore density was highest for A. conyzoides and lowest for P. notatum. Diversity index of the native AM fungi in the rhizosphere soil of P. notatum plants was slightly higher than those of S. gracilis and A. conyzoides plants. PCRDGGE analysis was consistent with the morphological results.
