Congenital Pseudarthrosis of Tibia:What's new?

来自南京医科大学、江苏省疾病预防控制中心、上海交通大学等多家机构的研究人员，通过全基因组关联研究（GWAS）鉴别出了我国汉族人群慢性乙型肝炎病毒（HBV）感染相关的两个全新易感基因。相关论文于近日刊登在国际顶级专业期刊《自然—遗传学》杂志上。\r\n \r\n乙型病毒性肝炎是一种由HBV感染机体后所引起的疾病。我国是乙肝大国，HBsAg携带率达8%—15%，并且慢性HBV感染也是引起肝硬化和肝细胞癌的最主要原因。由于宿主的天然免疫在机体抵抗HBV感染的过程中非常关键，因而除病毒和环境因素外，机体遗传因素即宿主对HBV的遗传易感性在乙型肝炎发病和预后等方面起着尤为重要的作用。\r\n \r\n在这项最新研究中，为了鉴别汉族人群中与慢性HBV感染相关的遗传位点，研究人员设计了一种三阶段全基因组关联研究。在发现阶段，他们对951名HBV携带者和937名已自然清除HBV感染的对照个体进行了分析。随后，在第二和第三重复阶段对来自一般人群的一组2248名HBV携带者和3051名对照个体，以及另一组1982名HBV携带者和2622名对照者进行了关联验证。\r\n \r\n他们鉴别出与慢性HBV感染相关的两个新位点：分别是靠近HLA-C以及在UBE2L3中。这些新研究结果表明HLA-C和UBE2L3也在HBV感染清除中发挥着重要的作用。新研究为乙肝的遗传病因提供了新的见解，对于乙肝的预防和治疗有可能具有重要的意义。\r\n

After decades of focusing almost exclusively on treating HIV, public health experts are now considering a new approach, moving to establish more effective prevention strategies to curb spread of the disease. Recent tests show that anti-HIV drugs that can hamper the growth of the virus responsible for AIDS may also prevent progression of the disease if given to infected individuals soon after their exposure to HIV. The same drugs can also prevent infections from taking hold among healthy people who are exposed to the virus; both approaches would be critical ways of controlling spread of the virus and keeping new cases of HIV to a minimum.\r\n\r\nRead more: http://healthland.time.com/2012/11/21/recommendations-for-routine-hiv-testing-represent-advances-in-preventing-hiv/#ixzz2CripWt9p

Breast cancer screening remains a subject of intense and, at times, passionate debate. Mammography has long been the mainstay of breast cancer detection and is the only screening test proven to reduce mortality. Although it remains the gold standard of breast cancer screening, there is increasing awareness of subpopulations of women for whom mammography has reduced sensitivity. Mammography also has undergone increased scrutiny for false positives and excessive biopsies, which increase radiation dose, cost, and patient anxiety. In response to these challenges, new technologies for breast cancer screening have been developed, including low-dose mammography, contrast-enhanced mammography, tomosynthesis, automated whole breast ultrasound, molecular imaging, and magnetic resonance imaging. Here we examine some of the current controversies and promising new technologies that may improve detection of breast cancer both in the general population and in high-risk groups, such as women with dense breasts. We propose that optimal breast cancer screening will ultimately require a personalized approach based on metrics of cancer risk with selective application of specific screening technologies best suited to the individual\\\'s age, risk, and breast density
