Purpose: The aim of this report is to describe the unusual MR imaging characteristics observed in two patients with biopsy-proven peliosis hepatis. Imaging findings using gadoxetate disodium (Eovist) as the contrast agent in a patient with peliosis hepatis are presented for the first time. Methods: This is a retrospective review of the MRI findings in two patients reviewed independently by two specialized abdominal imaging radiologists. The radiological findings were correlated with clinical history and histopathology. Results: Peliosis hepatis is a rare clinical and radiological entity that is often a diagnostic dilemma due to its non-specific clinical characteristics. Unusual imaging characteristics in this rare entity make diagnosis even more challenging. Conclusions: Improved understanding of the imaging characteristics of peliosis hepatis may prevent unnecessary and potentially dangerous biopsies in select patients with peliosis hepatis. This requires a high index of suspicion for practicing radiologists due to the rarity of this disease.

Hepatocellular Carcinoma (HCC) is a common malignancyworldwide. While bleeding from the gastrointestinal tract(BgIT) has a well known association with HCC, suchcases are mainly due to gastric and esophageal *** as a result of invasion of the gastrointestinal tractby HCC is extremely rare and is reportedly associatedwith very poor prognosis. We describe a 67-year-oldmale who presented with BgIT. Endoscopy showed thesite of bleeding to be from a gastric ulcer, but endoscopictherapy failed to control the bleeding and emergencysurgery was required. At surgery, the ulcer was found tohave arisen from direct invasion of the gastrointestinaltract by HCC of the left lobe. Control of the bleedingwas achieved by surgical resection of the HCC en-bloc with the lesser curve of the stomach. The patientremains alive 33 mo after surgery. Direct invasion of thegastrointestinal tract by HCC giving rise to BgIT is veryuncommon. Surgical resection may offer significantlybetter survival over non-surgical therapy, especially if thepatient is a good surgical candidate and has adequatefunctional liver reserves. Prognosis is not uniformly grave.

Hemorrhagic shock causes a reduction in oxygen supply to tissues leading to increased reactive oxygen species resulting in lung injury. Often mechanical ventilation is required as supportive treatment;however, ventilation can also induce lung injury and apoptosis. The purpose of this study was to examine the effects of three modes of controlled mechanical ventilation: volume control, pressure control, and pressure regulated volume control on lung injury as measured by hydrogen peroxide and apoptosis during hemorrhagic shock. Male Sprague-Dawley rats were randomized to the three controlled mechanical ventilation groups. Hemorrhagic shock was elicited by removing approximately 40% of the blood volume over 30 minutes. The rats were treated with one of three modes of mechanical ventilation with 40% oxygen for 60 minutes. The lungs were removed and measured for hydrogen peroxide and apoptosis based on nuclear differential dye uptake. There were no significant differences in hemodynamics, arterial blood values, peak inspiratory pressures, tidal volume, respiratory rates, and intrathoracic pressures across three groups. However, lung hydrogen peroxide production and apoptosis were significantly increased in volume control and pressure control, compared to pressure-regulated volume control. In this study, early signs of ventilator induced lung injury were not detected using commonly employed clinical measurements. However, when examining lung cellular injury (hydrogen peroxide and apoptosis), we were able to measure significant lung damage in volume control and pressure control, but not pressure-regulated volume control. Thus, our results suggest that pressure-regulated volume control is the preferable mode of mechanical ventilation during hemorrhagic shock.

生活中还需要学会放弃

疯狂英语（初中天地） 2014年第4期 16-19页

作者： David pierce Susan

在很多人眼里，“quitter”往往是贬义词，用来形容一个人轻易放弃。我们自小就被灌输一种思想：如果你跌倒了，不要放弃，站起来，继续。但我们是否要不顾一切地坚持，即使我们坚持的方向是错的呢？
