1肺栓塞的影像 应用螺旋CT的新观显示文摘肺栓塞是一种生前常被漏诊的疾病。其死亡率取决于诸多因素,未经治疗患者的年死亡率可高达 30%,是应用抗凝药物患者年死亡率(2.5%)的10倍以上。David M Hansell Christopher D R Flower 邢军 1998英国医学杂志中文版1998,0,1:13
2Dietary advanced glycation end-products aggravate non-alcoholic fatty liver disease显示文摘AIM To determine if manipulation of dietary advanced glycation end product(AGE), intake affects nonalcoholic fatty liver disease(NAFLD) progression and whether these effects are mediated via RAGE. METHODS Male C57Bl6 mice were fed a high fat, high fructose, high cholesterol(HFHC) diet for 33 wk and compared with animals on normal chow. A third group were given a HFHC diet that was high in AGEs. Another group was given a HFHC diet that was marinated in vinegar to prevent the formation of AGEs. In a second experiment, RAGE KO animals were fed a HFHC diet or a high AGE HFHC diet and compared with wildtype controls. Hepatic biochemistry, histology, picrosirius red morphometry and hepatic mR NA were determined. RESULTS Long-term consumption of the HFHC diet generated significant steatohepatitis and fibrosis after 33 wk. In this model, hepatic 4-hydroxynonenal content(a marker of chronic oxidative stress), hepatocyte ballooning, picrosirius red staining, α-smooth muscle actin and collagen type 1A gene expression were all significantly increased. Increasing the AGE content of the HFHC diet by baking further increased these markers of liver damage, but this was abrogated by pre-marination in acetic acid. In response to the HFHC diet, RAGE-/-animals developed NASH of similar severity to RAGE+/+ animals but were protected from the additional harmful effects of the high AGE containing diet. Studies in isolated Kupffer cells showed that AGEs increase cell proliferation and oxidative stress, providing a likely mechanism through which these compounds contribute to liver injury. CONCLUSION In the HFHC model of NAFLD, manipulation of dietary AGEs modulates liver injury, inflammation, and liver fibrosis via a RAGE dependent pathway. This suggests that pharmacological and dietary strategies targeting the AGE/RAGE pathway could slow the progression of NAFLD.Christopher Leung Chandana B Herath Zhiyuan Jia Sof Andrikopoulos Bronwyn E Brown Michael J Davies Leni R Rivera John B Furness Josephine M Forbes Peter W Angus 2016World Journal of Gastroenterology2016,22,35:7
3Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
4Second-generation direct-acting-antiviral hepatitis C virus treatment: Efficacy, safety, and predictors of SVR12显示文摘AIM To gather data on the antiviral efficacy and safety of second generation direct acting antiviral(DAA) treatment with respect to sustained virological response(SVR) 12 wk after conclusion of treatment, and to determine predictors of SVR12 in this setting.METHODS Two hundred and sixty patients treated with SOF combination partners PR(n = 51), R(n = 10), SMV(n = 30), DCV(n = 81), LDV(n = 73), or 3D(n = 15).144/260 were pre-treated, 89/260 had liver cirrhosis, 56/260 had portal hypertension with platelets < 100/nL, 25/260 had a MELD score ≥ 10 and 17/260 were postliver transplantation patients. 194/260 had HCV GT1, 44/260 HCV GT3.RESULTS Two hundred and forty/256(93.7%) patients achieved SVR12(m ITT); 4/260 were lost to follow-up. SVR12 rates for subgroups were: 92% for SOF/DCV, 93% for each SOF/SMV, SOF/PR, 94% for SOF/LDV, 100% for 3D, 94% for pretreated, 87% for liver cirrhosis, 82% for patients with platelets < 100/n L, 88% post-liver transplantation, 95% for GT1 a, 93% for GT1 b, 90% for GT3, 100% for GT2, 4, and 6. 12 patients suffered from relapse, 6 prematurely discontinued treatment, of which 4 died. Negative predictors of SVR12 were a platelet count < 100/nL, MELD score ≥ 10(P < 0.0001), liver cirrhosis(P = 0.005) at baseline. In Interferonfree treatment GT3 had significantly lower SVR rates than GT1(P = 0.016). Side effects were mild. CONCLUSION Excellent SVR12 rates and the favorable side-effect profile of DAA-combination therapy can be well translated into 'real-world'. Patients with advanced liver disease, signs of portal hypertension, especially with platelets < 100/n L and patients with GT3 are in special need for further research efforts to overcome comparatively higher rates of virological failure.Christoph R Werner Julia M Schwarz Daniel P Egetemeyr Robert Beck Nisar P Malek Ulrich M Lauer Christoph P Berg 2016World Journal of Gastroenterology2016,22,35:2
5Evolution of endovascular mechanical thrombectomy for acute ischemic stroke显示文摘Acute ischemic stroke(AIS) is a common medical problem associated with significant morbidity and mortality worldwide. A small proportion of AIS patients meet eligibility criteria for intravenous thrombolysis(IVT) with recombinant tissue plasminogen activator, and its efficacy for large vessel occlusion is poor. Therefore, an increasing number of patients with AIS are being treated with endovascular mechanical thrombectomy when IVT is ineffective or contraindicated. Rapid advancement in catheter-based and endovascular device technology has led to significant improvements in rates of cerebral reperfusion with these devices. Stentrievers and modern aspiration catheters have now surpassed earlier generation devices in the degree and rapidity of revascularization. This progress has been achieved with no concurrent increase in risk of major complications or mortality, both when used alone or in combination with IVT. The initial randomized controlled trials comparing endovascular therapy to IVT for AIS failed to show superior outcomes with endovascular treatment, butkey limitations of each trial may limit the significance of these results to current practice. While endovascular devices and operator experience continue to evolve, we are optimistic that this will be accompanied by improvements in patient outcomes. This review highlights the major endovascular devices used in current practice and the trials which have investigated their efficacy.Colin J Przybylowski Dale Ding Robert M Starke Christopher R Durst R Webster Crowley Kenneth C Liu 2014World Journal of Clinical Cases2014,2,11:2
