In the leaves of Liriodendroideae, some of the abaxial epidermal cells are papillose and the vascular tissue of the main vein appears to be separated. However, papillose were not found and there are uniseriate, multicellular or unicellular hairs distributed on the epidermis, and the vascular tissue of the main vein appears to be continuous in the leaves of Magnolioideae. Furthermore, in the Magnolioideae, the structure of the leaves of plants in Manglietia are different from that of Magnolia.

Objective To study the mechanism in which the personality, copying style influenced survival time by changing immunity function in the patients with gastric cancer Methods The Minnesota Multiphase Personality Inventory, coping style questionnaires and immunity function were measured in patients with gastric cancer on late stage, gastric cancer patients with longer survival time, and normal control Results Psychopathic deviate, social introversion subscale scores of MMPI in groupⅡ were significantly lower than that in the other two groups ( P 05) Statistical difference were found between groupⅠand groupⅡ in problem saving factor and help seeking factor of CSQ ( P 05) Natural killer cell level in groupⅡ was significantly higher than in groupⅠ( P 05) There was negative correlation between the NKC and depression, psychopathic deviate, paranoia, psychasthenia, schizophrenia subscale scores of MMPI, there was positive correlation between NKC and SP, coping type in patients with gastric cancer Conclusion The gastric cancer patients with longer survival time are more extroversive and have more mature coping styles Their NKC level is relatively higher The results may be advantageous to improve the prognosis of gastric cancer

作者中文名：王健；邹义壮；唐丽丽；李杰；张东；金山；刘娟摘要：目的研究胃癌患者的生存期与个性特征、应付方式等心理因素，以及免疫功能的关系。方法对胃癌晚期患者、胃癌较长生存期患者及正常健康人分别进行明尼苏达多相个性测验、应对方式问卷、免疫功能测试，并做相关分析。结果(1)MMPI：胃癌Ⅱ组人格障碍评分(42.0±10.5)及社会内向评分(42.2±11.6)，低于其他两组[胃癌Ⅰ组为(49.3±11.2)分和(48.3±9.4)分，对照组为(48.6±10.9)分和(39.9±11.5)分；P均＜0.05]；(2)CSQ：解决问题和求助因子分，胃癌Ⅰ组[分别为(0.68±0.27)分和(0.42±0.18)分]均低于胃癌Ⅱ组[分别为(0.82±0.18)分和(0.65±0.21)分；P＜0.05和P＜0.01]，胃癌Ⅱ组更多采取成熟的应对方式；(3)自然杀伤细胞：胃癌Ⅱ组水平(21.4±9.2)高于胃癌Ⅰ组[(14.2±8.8)；P＜0.05]；而NK细胞水平与MMPI的抑郁(r=-0.35)、人格障碍(r=-0.39)、偏执(r=-0.29)、精神衰弱(r=-0.30)及精神分裂(r=-0.30)等量表呈负相关，与CSQ的解决问题因子(r=0.35)及应付方式类型(r=0.34)呈正相关。结论与胃癌Ⅰ组比较，胃癌Ⅱ组更为外向，负性情绪较少，更多采取成熟的应对方式，其NK细胞水平较高，对胃癌的预后产生了积极的影响。

In order to elucidate the regulation mechanism of RU5 region to BFV gene expression, BFV3026 provirus DNA was used to construct the plasmids containing different deletion of R region, which were cotransfected with luc report gene locatied behind the IP promoter to BL12 cells, and luciferase activities was assayed, confirming that U5 region could repress the initiation function of LTR as well as IP. The BFV structure genes with different deletion of R region were cloned closely behind to heterogenous CMV promoter, then transfected to 293T cells, RT activity was performed, testifying the R region was required for BFV pol gene expression, and also the function domain was identified within the 100n.t. sequence at the 5′end.
