目前,表观基因调控能够触发前列腺癌的转移和引发雄激素非依赖性前列腺癌。组蛋白赖氨酸脱甲基酶（KDms）是一种可以去除抑制和激活组蛋白标记的表观酶。KDm5家族成员能够去除组蛋白H3赖氨酸4的二甲基化（一种激活标记）,致使它们成为下调肿瘤抑制的潜在成员,这表明它们的活性能够抑制癌基因。我们在两个独立的根治性前列腺癌切除术组（共822例前列腺肿瘤），采用免疫组化系统性分析KDm5C的表达模式。KDm5C标记细胞核阳性，与降低前列腺特异性抗原的无复发生存率显著相关。

＜正＞During the flight period of melolonlha hippocastani *** 1994 the following methods to reduce the damages of this species were tested in field and in combined field and laboratory studies:a) insecticides on the basis of natural substances:,,Neem Azal" agents（= seed extracts from the neem tree,Azadirachta indica）,,,ENVI-Repel"（= extracts from garlic plants）,b) biological insecticides:Beauveria brongniartii（= blastospore suspension of the insect-pathogenous fungi）,c) chemical insecticides:,,Rubitox"（active substance:phosalone）, ,,Decis"（active substance:deltamethrine）,d) mechanical methods:soil treatment with a rotary hoe. Under field conditions neem agents had no immediate letal or repellent effect on the beetles but resulted in changes of behaviour:defoliation decreased,the intake of food was subsided completely after two to three days,the flight activity and the egg production was almost perfectly reduced and the beetles did not look for any protection against rainy *** forced to feeding on neem treated leaves had no egg production under laboratory as under controlled field ***,,ENVI-Repel" agent did not show any repellent or disturbing *** were also no effects of Beauveria brongniartii because of the lost of spores ability to germinate.,,Rubitox" and,,Decis" showed an immediate letal effect within 3-4 hours which continued about 10 *** defoliation was reduced successfully. Negative side effects on other arthropode species were only recognised the day after the treatment with,,Decis".One week and four weeks after the application of the insecticides there were no significant differences on other species between treated and untreated areas.

mARK-J(马克杰)实验组的中期工作报告发表于1980年。本文是继该文之后的一个全面总结,也是对所有在mARK-J探测器上获得的包括公开发表过的或未曾公开发表过的全部结果的最新总结。由于有大量有兴趣的资料,我们感到一个全面而又连贯性的总结可能会对物理学界有用处。已经存在若干篇出色的关于高能正负电子对撞实验结果的汇编性的文献。为了使这篇总结报告满足各方面的需要,我们在第二章中加进了探测装置的概述。第三章中讨论数据的获取和分析处理。实际的物理结果不是按通常方式给出,而是随着分析过程给出相应的结果,这样比较实用。第四章给出仅涉及到轻子终态的结果;第五章给出关于强子终态的结果,第六章是上章的继续,但在更为复杂的检验QCD高度上进行总结。第七章总结了根据许多理论预言或实验兴趣进行的寻找各种新粒子的工作。

Uncoupling protein 2 deficiency of non-cancerous tissues inhibits the progression of pancreatic cancer in mice

Background: Pancreatic ductal adenocarcinoma(PDAC) is a disease of the elderly mostly because its development from preneoplastic lesions depends on the accumulation of gene mutations and epigenetic alterations over time. How aging of non-cancerous tissues of the host affects tumor progression, however, remains largely unknown. methods: We took advantage of a model of accelerated aging, uncoupling protein 2-deficient( Ucp2 knockout, Ucp2 KO) mice, to investigate the growth of orthotopically transplanted Ucp2 wild-type(WT) PDAC cells(cell lines Panc02 and 6606PDA) in vivo and to study strain-dependent differences of the PDAC microenvironment. Results: measurements of tumor weights and quantification of proliferating cells indicated a significant growth advantage of Panc02 and 6606PDA cells in WT mice compared to Ucp2 KO mice. In tumors in the knockout strain, higher levels of interferon-γ m RNA despite similar numbers of tumor-infiltrating T cells were observed. 6606PDA cells triggered a stronger stromal reaction in Ucp2 KO mice than in WT animals. Accordingly, pancreatic stellate cells from Ucp2 KO mice proliferated at a higher rate than cells of the WT strain when they were incubated with conditioned media from PDAC cells. Conclusions: Ucp2 modulates PDAC microenvironment in a way that favors tumor progression and implicates an altered stromal response as one of the underlying mechanisms.

世界核心医学期刊文摘（妇产科学分册） 2006年第2期2卷 53-54页

作者： Berner m.m. Wendt A Kriston L. rohde A. 马超 Dr. Abt. Psychiatrie und Psychotherapie Universittsklinikum Freiburg Hauptstrafle 5 79104 Freiburg Germany

Background: To date there is only a limited number of study data on the changes in the perceived quality of sexuality and relationships of women that occur with pregnancy and childbirth. Apart from prevalence issues predictors for those changes are important. These questions were addressed with this epidemiological follow-up study. methods: The study sample consisted of 236 women who gave birth to a child between November 2000 and may 2001 at Bonn University Hospital in Germany. A first visit took place at the hospital a few days after childbirth. Data included sociodemographic data, medical and gynecological data as well as personality traits using the NEO-FFI. A second visit took place 6.6 ±0.8 months after childbirth. It included the BSPS (Bonn Scale for Post-Partum Sexuality) and psychiatric symptoms using the SCL-90-R. Results: Approximately six months after childbirth 40.6%of women perceived a diminished quality of sexual life compared to the time before pregnancy. 23.2%indicated a diminished relationship quality. The potentially relevant co-variables regarding the changes in sexual quality were age, breast feeding, fertilization, use of contraceptives and presence of psychiatric symptoms. With the changes in relationship quality there were correlations with marital status, conscientiousness, and psychiatric symptom load. Discussion: The majority of women six months after childbirth did not return to a perceived sexual life comparable to the time before pregnancy. In addition to the high presence of symptoms of sexual dysfunction, the high psychosocial pressure is of special importance. Therefore the information of patients about the potential development of sexuality after childbirth and an integrative approach by the gynecologist seem important. Particularly the correlation between psychiatric symptom load and their predictive potential regarding satisfaction with sexuality should be accounted for in further epidemiological research.

我们回顾了矿用运输带或皮带的阻燃试验和欧洲的有关法规。在西德最重要的试验是“大型平行巷道试验”和“试验室平行巷道试验”。今天,由于氯丁橡胶固有的阻燃性能,它也被广泛地用来制造橡胶矿用传输带。本文介绍了一种称为XD型的特殊氯丁橡胶聚合物。与通用的硫醇型CR相比,由于XD型CR的特殊聚合结构,它改善了加工性能和物理机械性能。随着XD型CR越来越多的用做传输带胶料,可以愈来愈清楚地看出其优越性。 XD型和m型氯丁橡胶的差异表现在粘着胶料以及包复层胶料上。最后,本文给出了包括织物增强运输带和镀锌钢丝绳传输带用的有关包复层和胶清胶料配方的指导原则。
