摘要目的在儿童中,X线片用于诊断椎体骨折,而双能X线吸光测定法(DXA)用于评估骨密度。在成人中,DXA可评估上述两者。本研究旨在确定DXA能否取代脊柱X线片来评估小儿椎体骨折。方法前瞻性研究250例儿童同一天的侧位脊柱X线片和侧位脊柱D...

摘要目的在儿童中,X线片用于诊断椎体骨折,而双能X线吸光测定法(DXA)用于评估骨密度。在成人中,DXA可评估上述两者。本研究旨在确定DXA能否取代脊柱X线片来评估小儿椎体骨折。方法前瞻性研究250例儿童同一天的侧位脊柱X线片和侧位脊柱DXA,由3位放射医师采用简化的基于算法的定性技术(改良的ABQ,一种评价椎体骨折的技术)且在对其他结果未知的情况下进行独立评分。

对于许多神经退行性疾病来说。比如帕金森病、肌萎缩侧索硬化和外周神经病变，轴突的损失是一个早期的缺陷。当轴突出现损失。神经细胞就无法正常交流，神经系统功能受到损伤。特别是对外周神经病变来说，受损的轴突会触发自毁程序。在一项新研究中。华盛顿大学医学院的科学家们在自毁的轴突中发现一个特殊分子。深入了解损伤如何发生有助于帮助找到阻止其发生的方法。相关研究结果发表在国际学术期刊Neuron上。

猪鞭虫治疗克罗恩病

世界核心医学期刊文摘（胃肠病学分册） 2005年第5期1卷 30-31页

Background: Crohns disease is common in highly industrialised Western countries where helminths are rare and uncommon in less developed areas of the world where most people carry worms. Helminths diminish immune responsiveness in naturally colonised humans and reduce inflammation in experimental colitis. Thus exposure to helminths may help prevent or even ameliorate Crohns disease. Aims: The aim of the study was to determine the safety and possible efficacy of the intestinal helminth Trichuris suis in the treatment of patients with active Crohns disease. Patients: Twenty nine patients with active Crohns disease, defined by a Crohns disease activity index (CDAI) ≥220 were enrolled in this open label study. Methods: All patients ingested 2500 live T suis ova every three weeks for 24 weeks, and disease activity was monitored by CDAI. Remission was defined as a decrease in CDAI to less than 150 while a response was defined as a decrease in CDAI of greater than 100. Results: At week 24, 23 patients (79.3%) responded (decrease in CDAI >100 points or CDAI sponders decreased 177.1 points below baseline. Analysis at week 12 yielded similar results. There were no adverse events. Conclusions: This new therapy may offer a unique, safe, and efficacious alternative for Crohns disease management. These findings also support the premise that natural exposure to helminths such as T suis affords protection from immunological diseases like Crohns disease.

ENsO induces coherent climate anomalies over the Indo-western Pacific, but these anomalies outlast ssT anomalies of the equatorial Pacific by a season, with major effects on the Asian summer monsoon. This review provides historical accounts of major milestones and synthesizes recent advances in the endeavor to understand summer variability over the Indo-Northwest Pacific region. specifically, a large-scale anomalous anticyclone （AAC） is a recurrent pattern in post-E1 Nifio summers, spanning the tropical Northwest Pacific and North Indian oceans. Regarding the ocean memory that anchors the summer AAC, competing hypotheses emphasize either ssT cooling in the easterly trade wind regime of the Northwest Pacific or ssT warming in the westerly monsoon regime of the North Indian Ocean. Our synthesis reveals a coupled ocean- atmosphere mode that builds on both mechanisms in a two-stage evolution. In spring, when the northeast trades prevail, the AAC and Northwest Pacific cooling are coupled via wind-evaporation-ssT feedback. The Northwest Pacific cooling persists to trigger a summer feedback that arises from the interaction of the AAC and North Indian Ocean warming, enabled by the westerly monsoon wind regime. This Indo-western Pacific ocean capacitor （IPOC） effect explains why E1 Nifio stages its last act over the monsoonal Indo-Northwest Pacific and casts the Indian Ocean warming and AAC in leading roles. The IPOC displays interdecadal modulations by the ENsO variance cycle, significantly correlated with ENsO at the turn of the 20th century and after the 1970s, but not in between. Outstanding issues, including future climate projections, are also discussed.
