烫伤后用针挑破水泡很危险

烫伤后的水疱是万万不可以挑破的。因为完整的皮肤是人体抵御细菌入侵的屏障，一旦挑破，则细菌即会很快入侵．发生感染。     

基于威胁度的动态报警管理研究

IDS目前的主要问题之一是过高的误报率,这一方面给管理员增加了繁重的工作负担,从而使其可能忽视了系统中真正需要处理的关键攻击事件;另一方面,过高的误报率使得自动入侵响应,比如与防火墙联动,不能很好地执行下去.针对这个问题,提出了基于威胁度的动态报警管理TDAM模型,它通过对系统环境的感知分析报警信息,确定其威胁度.通过实验,可以得出TDAM框架能够比较好地进行报警评价、管理.     

我国外来生物入侵现状和立法分析

目前入侵我国的外来生物已达400余种，近10年来，新入侵我国的外来入侵生物至少有20余种，平均每年递增1～2种。我国已经成为遭受外来入侵生物危害最严重的国家之一，面临的防制形势越来越严峻。目前我国已有多种涉及外来有害生物的相关法规与管理条例，但大多仅适用于预防已知的检疫对象，尚缺乏针对外来入侵生物的专门法规与管理条例。因此，有必要制定专门的外来入侵生物预防与管理法规、条例与实施细则，制定国家对外来人侵生物预防与控制的指导准则及行动指南。另外，我国存在管理体制不健全，缺乏统一组织协调，缺乏完善的监测等缺陷。

Androgen receptor functioned as a suppressor in the prostate cancer cell line PC3 in vitro and in vivo

Background Prostate cancer is one of the most common urogenital tumors in the world with an increasing incidence in China. Androgen deprivation therapy is the major therapeutic option for advanced prostate cancer. However, the role of androgen receptor （AR） in hormone-refractory prostate cancer still remains unclear. This work aimed to investigate the role of AR in an androgen independent prostate cancer cell line by in vitro and in vivo studies.
Methods The role of AR in the proliferation and invasion/metastasis ability of PC3-AR9 （a PC3 stable clone expressing human AR driven by natural human AR promoter） were examined with M-IF assay, soft agar assay, chamber invasion assay, wound healing assay, and also with orthotopic xenograft mouse model. Results Restoring androgen receptor in PC3 cells resulted in decreased proliferation and invasion/metastasis ability in MTT, soft agar, chamber invasion and wound healing assay. In the mouse orthotopic xenograft model, PC3-AR9 resulted in smaller primary tumors and metastasis tumors, with a lower proliferation rate and higher apoptosis rate.
Conclusion The AR might function as a tumor suppressor in PC3 cells both in vitro and in vivo.     

Malignant priapism secondary to testicular tumor

Malignant priapism is an uncommon clinical disease .characterized by prolonged erection secondary to the invasion of malignant neoplasm into corpora cavernosa） Penile metastasis of malignant tumors is relatively rare, and only approximately 370 cases were reported by 2006 from a wide range of primary sites with a descending order of the prostate 125 （34%）, bladder 112 （30%） and recto-sigmoid ＋ rectum 48 （13%）; only 11 cases of malignant priapisms （3%） were attributed to penile metastasis of testicular tumors. Here, we present an interesting case of malignant priapism caused by penile metastasis of a mixed germ cell tumor of the testes in a 25-year-old man.
