objective to evaluate the role of mr perfusion weighted imaging in preoperation diagnosis of meningiomas.methods mr perfusion weighted images was performed in 47 patients with meningiomas followed by conventional imaging.results the mean rcbv values of angioblastic was the highest in the parenchyma of tumor.the mean rcbv values of malignant group was the lowest.the biggest mean rcbv values among different type meningiomas was statistically significant.the biggest mean rcbv values between benign and malignant group meningiomas was statistically significant,but not in the peri-tumor edema.conclusion the rcbv values were useful in the preoperative differentiation diagnosis of different types of meningiomas.those in the peri-tumor edema were useless in the preoperative differentiation diagnosis of different types of meningiomas.

目的 探讨磁共振灌注成像技术对脑膜瘤术前分型及良恶性鉴别的临床应用价值。方法对47例脑膜瘤病人行mr灌注成像检查，对5种亚型的良性脑膜瘤的mr灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。结果血管瘤型脑膜瘤实质部分的rcbv值均数最高，恶性组脑膜瘤的rcbv值均数最低。各亚型间瘤体实质最大rcbv值均数间差异有统计学意义(p＜0.05)，良恶性脑膜瘤实质部分最大rcbv值均数间差异有统计学意义(p＜0.05)。瘤周水肿区的rcbv值均数间差异无统计学意义(p＞0.05)。结论 rcbv值对脑膜瘤术前分型及良恶性鉴别有所帮助，而瘤周水肿区的rcbv值对脑膜瘤分型及良恶性鉴别未显示临床实用价值。

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。
