目的评估小儿低剂量心血管CT血管成像(CTA)的影像质量(IQ),将影像空间迭代重建(IRIS)及基于原始数据的迭代重建(SAFIRE)技术与滤过反向投影(FBP)技术进行比较,并评价进一步降低剂量的可能性。方法 40例有或无心电门控的新生儿和儿童行低剂量CTA检查。应用FBP、IRIS及SAFIRE技术进行数据重建。对于ECG门控的研究,模拟半剂量影像采集。测量信号噪声并对IQ进行分级。评价有效剂量(ED)。结果应用IRIS及全剂量SAFIRE技术,影像噪声平均绝对值和相对值低于FBP(P<0.001),而SNR及CNR则高于FBP(P<0.001)。与全及半剂量FBP研究相比,半剂量SAFIRE影像噪声也较低,SNR及CNR较高(P<0.001)。IRIS、全剂量SAFIRE及半剂量SAFIRE的IQ评分高于全剂量FBP,半剂量SAFIRE的IQ评分高于半剂量FBP(P<0.05)。中位数特别权重ED在没有ECG门控时为0.3mSv,有ECG门控时为1.36mSv。半剂量SAFIRE研究的ED评价为0.68mSv。结论在低剂量小儿CTA检查中,与FBP相比,IR技术可改善影像噪声、SNR、CNR及主观的IQ,并可在不影响诊断IQ的前提下进一步降低剂量。要点①迭代重建技术显著改善儿童无创性心血管CT检查。②使用一半常规放射剂量时,迭代重建的影像质量更高。③应用迭代重建技术可以进一步降低小儿心血管CT的放射剂量。

Ceruloplasmin (CP) is an abundant serum alpha-2 glycoprotein. In the brain, the greatest expression of CP is found in astrocytes surrounding the brain microvasculature. The glycosylphosphatidylinositol-anchored CP (GPI-CP) is the predominant form of this protein in the brain. Humans with mutations of the CP gene (aceruloplasminemia) can lead to brain iron accumulation and neurodegeneration. It implies that CP is essential for brain iron homeostasis. However, its precise function in brain iron transport has not been well determined. In this study, we investigated the effects of soluble CP on iron influx and efflux in primary neuronal culture

Context: Many men with inguinal hernia have minimal symptoms. Whether deferring surgical repair is a safe and acceptable option has not been assessed. Objective: To compare pain and the physical component score (PCS) of the Short Form-36 Version 2 survey at 2 years in men with minimally symptomatic inguinal hernias treated with watchful waiting or surgical repair. Design, Setting, and Participants: Randomized trial conducted January 1, 1999, through December 31, 2004, at 5 North American centers and enrolling 720 men (364 watchful waiting, 356 surgical repair) followed up for 2 to 4.5 years. Interventions: Watchful-waiting patients were followed up at 6 months and annually and watched for hernia symptoms; repair patients received standard open tensionfree repair and were followed up at 3 and 6 months and annually. Main Outcome Measures: Pain and discomfort interfering with usual activities at 2 years and change in PCS from baseline to 2 years. Secondary outcomes were complications, patient-reported pain, functional status, activity levels, and satisfaction with care. Results: Primary intention-to-treat outcomes were similar at 2 years for watchful waiting vs surgical repair: pain limiting activities (5.1%vs 2.2%, respectively; P=.52); PCS (improvement over baseline, 0.29 points vs 0.13 points; P=.79). Twenty-three percent of patients assigned to watchful waiting crossed over to receive surgical repair (increase in hernia-related pain was the most common reason offered); 17%assigned to receive repair crossed over to watchful waiting. Self-reported pain in watchful-waiting patients crossing over improved after repair. Occurrence of postoperative hernia-related complications was similar in patients who received repair as assigned and in watchful-waiting patients who crossed over. One watchful-waiting patient (0.3%) experienced acute hernia incarceration without strangulation within 2 years; a second had acute incarceration with bowel obstruction at 4 years, with a freq
