Biodegradable metals as electrodes, interconnectors, and device conductors are essential components in the emergence of transient electronics, either for passive implants or active electronic devices, especially in the fields of biomedical electronics. Magnesium and its alloys are strong candidates for biodegradable and implantable conducting materials because of their high conductivity and biocompatibility, in addition to their well-understood dissolution behavior. One critical drawback of Mg and its alloys is their considerably high dissolution rates originating from their low anodic potential, which disturbs the compatibility to biomedical applications. Herein, we introduce a single-phase thin film of a Mg-Zn binary alloy formed by sputtering, which enhances the corrosion resistance of the device electrode, and verify its applicability in biodegradable electronics. The formation of a homogeneous solid solution of single-phase Mg-3Zn was confirmed through X-ray diffraction and transmission electron microscopy. In addition, the dissolution behavior and chemistry was also investigated in various biological fluids by considering the effect of different ion species. Micro-tensile tests showed that the Mg-3Zn alloy electrode exhibited an enhanced yield strain and elongation in relation to a pure Mg electrode. Cell viability test revealed the high biocompatibility rate of the Mg-3Zn binary alloy thin film. Finally, the fabrication of a wireless heater demonstrated the integrability of biodegradable electrodes and highlighted the ability to prolong the lifecycle of thermotherapy-relevant electronics by enhancing the dissolution resistance of the Mg alloy.

Intracerebral hemorrhage （ICH）, caused by the sudden rupture of an artery within the brain, is a devastating subtype of stroke, which currently has no effective treatment. Intense inflammatory reactions that occur in the peri-hematomal area after ICH are more deleterious than the hematoma itself, resulting in subsequent brain edema and neurologic deterioration. Thus, we developed lipid-coated magnetic mesoporous silica nanoparticles doped with ceria nanoparticles （CeNPs）, abbreviated as LMCs, which have both potent anti-inflammatory therapeutic effects via scavenging reactive oxygen species and help in increasing the efficacy of magnetic resonance imaging enhancement in the peri-hematomal area. LMCs consist of mesoporous silica nanopartide-supported lipid bilayers, which are loaded with large amounts of CeNPs for scavenging of reactive oxygen species, and iron oxide nanoparticles for magnetic resonance imaging contrast. LMCs loaded with CeNPs exhibited strong anti-oxidative and anti-inflammatory activities in vitro. In the rodent ICH model, intracerebraUy injected LMCs reached the peri-hematomal area and were engulfed by macrophages, which were clearly visualized by magnetic resonance imaging of the brain. Moreover, LMCs reduced inflammatory macrophage infiltration, and thus significantly reduced brain edema. Finally, LMC treatment markedly improved neurologic outcomes of the animals with ICH. Thus, LMC is the first nanobiomaterial that successfully showed theragnostic effects in ICH.

To investigate the characteristic radiologic findings of cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) which can be differentiated from other similar bowel disease and to assess their clinical behavior. METHODSTwenty pathologically and clinically confirmed CMUSE patients (males:females = 8:12; mean age: 40.4 years) between March 2002 and August 2015 from seven academic centers in South Korea were retrospectively reviewed. We evaluated small bowel series (SBS; n = 25), computed tomography (CT) enterography (n = 21), magnetic resonance (MR) enterography (n = 2), and abdominopelvic CT (n = 18) images, focusing on enteric and perienteric manifestations. Any change in radiologic features during follow-up period was recorded. We evaluated clinical data including presenting symptoms, laboratory finding and presence of relapse from electronic medical records. Histopathologic findings were also evaluated. RESULTSThe main symptoms were abdominal pain (n = 12) and anemia (n = 10). All patients showed small bowel strictures (n = 52, mean: 2.6 per patient) on initial CT/MR, located in the ileum (n = 47) or jejunum (n = 5). Strictures showed short-length (mean: 10.44 mm) and circumferential bowel wall thickening (mean: 5.56 mm) with layered enhancement (n = 48) that were also noted on initial SBS (n = 36) with shallow ulcers (n = 10). Some ulcerative lesions or wall thickening progressed into strictures on follow-up SBS/CT, and some strictures revealed recurrent ulceration on follow-up SBS. There were no penetrating disease features like fistula or abscess and no gastrointestinal tract involvement except the small bowel. Nine patients experienced disease recurrence (median relapse-free period: 32 mo) even post-operatively. Histopathologic features of surgically resected specimens were characterized as multiple superficial ulcerations confined to mucosa or submucosa and multiple strictures. CONCLUSIONUnder characteristic radiologic findings with multiple short-segmen

AIM：To evaluate the effect of exogenous recombinant human bone morphogenic protein-7（rhBMP-7）on transforming growth factor-β（TGF-β）-induced epithelial mesenchymal cell transition（EMT）and assessed its antifibrotic effect via topical ***：The cytotoxic effect of rhBMP-7 was evaluated and the EMT of human corneal epithelial cells（HECEs）was induced by TGF-β. HECEs were then cultured in the presence of rhBMP-7 and/or hyaluronic acid（HA）. EMT markers,fibronectin,E-cadherin,α-smooth muscle actin（α-SMA）,and matrix metaloproteinase-9（MMP-9）,were evaluated. The level of corneal fibrosis and the reepithelization rate were evaluated using a rabbit keratectomy model. Expression of α-SMA in keratocytes were quantified following treatment with different concentrations of ***：Treatment with rhBMP-7 attenuated TGF-β-induced EMT in HECEs. It significantly attenuated fibronectin secretion（31.6%; P〈0.05）,the α-SMA protein level（72.2%; P〈0.01）,and MMP-9 expression（23.6%,P〈0.05）in HECEs compared with cells grown in the presence of TGF-β alone. E-cadherin expression was significantly enhanced（289.7%; P〈0.01）in the presence of rhBMP-7. Topical application of rhBMP-7 combined with 0.1% HA significantly reduced the amount of α-SMA~＋ cells by 43.18%（P〈0.05）at a concentration of 2.5 μg/mL and by 47.73%（P〈0.05）at 25 μg/mL,compared with the control group,without disturbing corneal ***：rhBMP-7 attenuates TGF-β-induced EMT in vitro,and topical application of rhBMP-7 reduces keratocyte myodifferentiation during the early wound healing stages in vivo without hindering reepithelization. Topical rhBMP-7 application as biological eye drops seems to be feasible in diseases involving TGF-β-related corneal fibrosis with corneal reepithelization disorders.

In the present study, we used immunohistochemistry and western blot analysis to examine changes in the levels and cellular localization of iron, heavy chain ferritin（ferritin-H）, and transferrin in the gerbil hippocampal CA1 region from 30 minutes to 7 days following transient forebrain ischemia. Relative to sham controls, iron reactivity increased significantly in the stratum pyramidale and stratum oriens at 12 hours following ischemic insult, transiently decreased at 1–2 days and then increased once again within the CA1 region at 4–7 days after ischemia. One day after ischemia, ferritin-H immunoreactivity increased significantly in the stratum pyramidale and decreased at 2 days. At 4–7 days after ischemia, ferritin-H immunoreactivity in the glial components in the CA1 region was significantly increased. Transferrin immunoreactivity was increased significantly in the stratum pyramidale at 12 hours, peaked at 1 day, and then decreased significantly at 2 days after ischemia. Seven days after ischemia, Transferrin immunoreactivity in the glial cells of the stratum oriens and radiatum was significantly increased. Western blot analyses supported these results, demonstrating that compared to sham controls, ferritin H and transferrin protein levels in hippocampal homogenates significantly increased at 1 day after ischemia, peaked at 4 days and then decreased. These results suggest that iron overload-induced oxidative stress is most prominent at 12 hours after ischemia in the stratum pyramidale, suggesting that this time window may be the optimal period for therapeutic intervention to protect neurons from ischemia-induced death.

Distant skeletal muscle metastasis from intrahepatic cholangiocarcinoma presenting as Budd-Chiari syndrome

引用

World Journal of Gastroenterology 2007年第22期13卷 3141-3143页

作者： Oh Sung Kwon Dae Won jun Sang Heum Kim Mee yeon Chung Nam In Kim Moon Hee Song Han Hyo Lee Seung Hwan Kim Yoon ju Jo Young Sook Park Jong Eun Joo Department of Internal Medicine Eulji University Hospital Seoul Korea Department of Radiology Eulji University Hospital Seoul Korea Department of Pathology Eulji University Hospital Seoul Korea

Intrahepatic cholangiocarcinoma is a malignant neoplasm arising from the biliary epithelium, which frequently invades adjacent organs or metastasizes to other visceral organs such as the lungs, bones, adrenals, and brain. However, distant skeletal muscle metastasis of cholangiocarcinoma has never been described before to the best of our knowledge and, furthermore, Budd-Chiari syndrome secondary to intrahepatic cholangiocarcinoma is also extremely rare. Here we present the first case overall of distant muscle metastasis from intrahepatic cholangiocarcinoma presenting as Budd-Chiari syndrome. A 44-year-old man admitted to the hospital with complaints of abdominal distension, edema of both legs, back pain and anorexia of 30 d' duration. Computed tomography and ultrasonography-guided percutaneous muscle biopsy established intrahepatic cholangiocarcinoma with disseminated thrombosis from inferior vena cava to bilateral iliac and femoral veins, and multiple skeletal muscle metastases in bilateral buttock and erector spinal muscle.
