| 1 | Radioembolization for the treatment of unresectable hepatocellular carcinoma:A clinical review显示文摘Hepatocellular carcinoma(HCC)is the sixth most common cancer in the world.The majority of patients with HCC present with unresectable disease.These patients have historically had limited treatment options secondary to HCC demonstrating chemoresistance to the currently available systemic therapies.Additionally, normal liver parenchyma has shown intolerance to tumoricidal radiation doses,limiting the use of external beam radiation.Because of these limitations,novel percutaneous liver-directed therapies have emerged. The targeted infusion of radioactive microspheres (radioembolization)represents one such therapy. Radioembolization is a minimally invasive transcatheter therapy through which radioactive microspheres are infused into the hepatic arteries that supply tumor. Once infused,these microspheres traverse the hepatic vascular plexus and selectively implant within the tumor arterioles.Embedded within the arterioles, the 90Y impregnated microspheres emit high energy and low penetrating radiation doses selectively to the tumor.Radioembolization has recently shown promise for the treatment of patients with unresectable HCC. The objective of this review article is to highlight twocurrently available radioembolic devices(90Y,188Rh)and provide the reader with a recent review of the literature. | Saad M Ibrahim Robert J Lewandowski Kent T Sato Vanessa L Gates Laura Kulik Mary F Mulcahy Robert K Ryu Reed A Omary Riad Salem | 2008 | World Journal of Gastroenterology2008，14，11： | 14 |
| 2 | Diffusion-weighted magnetic resonance imaging to predict response of hepatocellular carcinoma to chemoembolization显示文摘AIM: To investigate whether intra-procedural diffusion- weighted magnetic resonance imaging can predict response of hepatocellular carcinoma (HCC) during trans- catheter arterial chemoembolization (TACE). METHODS: Sixteen patients (15 male), aged 59 ±11 years (range: 42-81 years) underwent a total of 21 separate treatments for unresectable HCC in a hybrid magnetic resonance/interventional radiology suite. Ana- tomical imaging and diffusion-weighted imaging (b = 0, 500 s/mm2) were performed on a 1.5-T unit. Tumor enhancement and apparent diffusion coefficient (ADC, mm2/s) values were assessed immediately before and at 1 and 3 mo after TACE. We calculated the percent change (PC) in ADC values at all time points. We compared follow-up ADC values to baseline values using a paired t test (α = 0.05). RESULTS: The intra-procedural sensitivity, specificity, and positive and negative predictive values (%) for detecting a complete or partial 1-mo tumor response using ADC PC thresholds of ±5%, ±10%, and ±15% were 77, 67, 91, and 40; 54, 67, 88, and 25; and 46, 100, 100, and 30, respectively. There was no clear predictive value for the 3-mo follow-up. Compared to baseline, the immediate post-procedure and 1-mo mean ADC values both increased; the latter obtaining statistical significance (1.48 ± 0.29 mm2/s vs 1.65 ± 0.35 × 10-3 mm2/s, P < 0.014). CONCLUSION: Intra-procedural ADC changes of > 15% predicted 1-mo anatomical HCC response with the greatest accuracy, and can provide valuable feedback at the time of TACE. | Johnathan C Chung Neel K Naik Robert J Lewandowski Mary F Mulcahy Laura M Kulik Kent T Sato Robert K Ryu Riad Salem Andrew C Larson Reed A Omary | 2010 | World Journal of Gastroenterology2010，16，25： | 13 |

| 4 | Microscopic colitis:A large retrospective analysis from a health maintenance organization experience显示文摘AIM:To examine the demographic data on a large multi-ethnic population of patients with microscopic colitis (MC) in Southern California and to determine the association of MC with inflammatory bowel disease (IBD) and colorectal cancer.METHODS: All patients diagnosed with MC by colonic biopsy from 1996-2005 were identified utilizing a pathology database. All biopsies were reviewed by experienced pathologists utilizing standard histologic criteria. Patients' medical records were reviewed and data regarding patient age, co-morbidities, sex, ethnicity, and medications were analyzed. An age-and sexmatched standard control group was also generated. Chi-square test was used to evaluate the associations of co-morbidities between lymphocytic colitis (LC), collagenous colitis (CC) and the control group.RESULTS: A total of 547 cases of MC were identif ied,376 patients with LC and 171 patients with CC. The female/male ratio was 3:1 in CC and 2.7:1 in LC patients. Celiac disease (P<0.001), irritable bowel syndrome (IBS) (P<0.001), and thyroid diseases (P<0.001) were found to have a higher occurrence in MC compared to the control group. No statistical differences in the occurrence of colorectal cancer, diabetes and IBD were found between the MC group and the control group.CONCLUSION: This is the largest group of patients with MC known to the authors that has been studied to date. Conditions such as celiac disease, IBS, and thyroid diseases were found to be related to MC. Furthermore, neither an increased risk of colorectal cancer nor IBD was associated with MC in this study. | Kevin T Kao Benito A Pedraza Amy C McClune David A Rios Yi-Qiong Mao Robert H Zuch Michael H Kanter Sony Wirio Chris N Conteas | 2009 | World Journal of Gastroenterology2009，15，25： | 5 |
| 5 | Clinical 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 | 2014 | World Journal of Clinical Oncology2014，5，2： | 5 |
| 6 | Acute effects of rotavirus and malnutrition on intestinal barrier function in neonatal piglets显示文摘AIM: To investigate the effect of protein-energy malnutrition on intestinal barrier function during rotavirus enteritis in a piglet model.METHODS: Newborn piglets were allotted at day 4 of age to the following treatments:(1) full-strength formula(FSF)/noninfected;(2) FSF/rotavirus infected;(3) half-strength formula(HSF)/noninfected;or(4) HSF/rotavirus infected.After one day of adjustment to the feeding rates,pigs were infected with rotavirus and acute effects on growth and diarrhea were monitored for 3 d and jejunal samples were collected for Ussingchamber analyses.RESULTS: Piglets that were malnourished or infected had lower body weights on days 2 and 3 post-infection(P < 0.05).Three days post-infection,marked diarrhea and weight loss were accompanied by sharp reductions in villus height(59%) and lactase activity(91%) and increased crypt depth(21%) in infected compared with non-infected pigs(P < 0.05).Malnutrition also increased crypt depth(21%) compared to full-fed piglets.Villus:crypt ratio was reduced(67%) with viral infection.There was a trend for reduction in transepithelial electrical resistance with rotavirus infection and malnutrition(P = 0.1).3H-mannitol flux was significantly increased(50%;P < 0.001) in rotavirus-infected piglets compared to non-infected piglets,but there was no effect of nutritional status.Furthermore,rotavirus infection reduced localization of the tight junction protein,occludin,in the cell membrane and increased localization in the cytosol.CONCLUSION: Overall,malnutrition had no additive effects to rotavirus infection on intestinal barrier function at day 3 post-infection in a neonatal piglet model. | Sheila K Jacobi Adam J Moeser Anthony T Blikslager J Marc Rhoads Benjamin A Corl Robert J Harrell Jack Odle | 2013 | World Journal of Gastroenterology2013，19，31： | 4 |
| 7 | Pyruvate-fortified resuscitation stabilizes cardiac electrical activity and energy metabolism during hypovolemia显示文摘AIM: To test the hypothesis that fluid resuscitation with Ringer's solution enriched with pyruvate(PR), a physiological antioxidant and energy substrate, affords protection of myocardial metabolism and electrophysiological performance superior to lactated Ringer's(LR) during hypovolemia and hindlimb ischemia-reperfusion.METHODS: Male domestic goats(25-30 kg) were exsanguinated to a mean arterial pressure of 48 ± 1 mm Hg. Right hindlimb ischemia was imposed for 90 min by applying a tourniquet and femoral crossclamp. LR or PR, infused iv, delivered 0.05 mmol/kg per minute L-lactate or pyruvate, respectively, from 30 min hindlimb ischemia until 30 min post-ischemia. Time controls(TC) underwent neither hemorrhage, hindlimb ischemia nor resuscitation. Goats were sacrificed and left ventricular myocardium biopsied at 90 min fluid resuscitation(n = 6 per group) or 3.5 h later(n = 9 LR, 10 PR, 8 TC).RESULTS: Myocardial 8-isoprostane content, phosphocreatine phosphorylation potential, creatine kinase activity, and heart rate-adjusted QT interval(QTc) vari- ability were evaluated at 90 min resuscitation and 3.5 h post-resuscitation. PR sharply lowered pro-arrhythmic QTc variability vs LR(P < 0.05); this effect persisted 3.5 h post-resuscitation. PR lowered myocardial 8-isoprostane content, a product of oxidative stress, by 39 and 37% during and 3.5 h after resuscitation, respectively, vs LR. Creatine kinase activity fell 42% post-LR vs TC(P < 0.05), but was stable post-PR(P < 0.02 vs post-LR). PR doubled phosphocreatine phosphorylation potential, a measure of ATP free energy state, vs TC and LR(P < 0.05); this energetic enhancement persisted 3.5 h post-resuscitation.CONCLUSION: By augmenting myocardial energy state and protecting creatine kinase activity, pyruvateenriched resuscitation stabilized cardiac electrical function during central hypovolemia and hindlimb ischemiareperfusion. | Hunaid A Gurji Daniel W White Besim Hoxha Jie Sun Albert H Olivencia-Yurvati Robert T Mallet | 2013 | World Journal of Critical Care Medicine2013，2，4： | 3 |
| 8 | Benefits of the use of blood conservation in scoliosis surgery显示文摘AIM To investigate whether autologous blood transfusion(ABT) drains and intra-operative cell salvage reduced donor blood transfusion requirements during scoliosis surgery.METHODS Retrospective data collection on transfusion requirements of patients undergoing scoliosis surgery is between January 2006 and March 2010. There were three distinct phases of transfusion practice over this time: Group A received 'traditional treatment' with allogeneic red cell transfusion(ARCT) in response to an intra- or postoperative anaemia(Hb < 8 g/d L or a symptomatic anaemia); Group B received intra-operative cell salvage in addition to 'traditional treatment'. In group C,ABT wound drains were used together with both intra-operative cell salvage and 'traditional treatment'.RESULTS Data from 97 procedures on 77 patients,there was no difference in mean preoperative haemoglobin levels between the groups(A: 13.1 g/d L; B: 13.49 g/d L; C: 13.66 g/d L). Allogeneic red cell transfusion was required for 22 of the 37 procedures(59%) in group A,17 of 30(57%) in group B and 16 of 30(53%) in group C. There was an overall 6% reduction in the proportion of patients requiring an ARCT between groups A and C but this was not statistically significant(χ2 = 0.398). Patientsin group C received fewer units(mean 2.19) than group B(mean 2.94)(P = 0.984) and significantly fewer than those in group A(mean 3.82)(P = 0.0322). Mean length of inpatient stay was lower in group C(8.65 d) than in groups B(12.83) or A(12.62).CONCLUSION When used alongside measures to minimise blood loss during surgery,ABT drains and intra-operative cell salvage leads to a reduced need for donor blood transfusion in patients undergoing scoliosis surgery. | Peter R Loughenbury Lyeanda Berry Ben T Brooke Abhay S Rao Robert A Dunsmuir Peter A Millner | 2016 | World Journal of Orthopedics2016，7，12： | 3 |
| 9 | Mutifactorial analysis of risk factors for reduced bone mineral density in patients with Crohn’s disease显示文摘AIM: To determine the prevalence of osteoporosis in a cohort of patients with Crohn’s disease (CD) and to identify the relative significance of risk factors for osteoporosis. METHODS: Two hundred and fifty-eight unselected patients (92 M, 166 F) with CD were studied. Bone mineral density (BMD) was measured at the lumbar spine and hip by dual X-ray absorptiometry. Bone formation was assessed by measuring bone specific alkaline phosphatase (BSAP) and bone resorption by measuring urinary excretion of deoxypyridinoline (DPD) and N-telopeptide (NTX). RESULTS: Between 11.6%-13.6% patients were osteoporotic (T score < -2.5) at the lumbar spine and/or hip. NTX levels were significantly higher in the patients with osteoporosis (P < 0.05) but BSAP and DPD levels were not significantly different. Independent risk factors for osteoporosis at either the lumbar spine or hip were a low body mass index (P < 0.001), increasing corticosteroid use (P < 0.005), and male sex (P < 0.01). These factors combined accounted for 23% and 37% of the reduction in BMD at the lumbar spine and hip respectively. CONCLUSION: Our results confirm that osteoporosis is common in patients with CD and suggest that increased bone resorption is the mechanism responsible for thebone loss. However, less than half of the reduction in BMD can be attributed to risk factors such as corticosteroid use and low BMI and therefore remains unexplained. | Sarah A Bartram Robert T Peaston David J Rawlings David Walshaw Roger M Francis Nick P Thompson | 2006 | World Journal of Gastroenterology2006，12，35： | 2 |

| 11 | Modeling cardiac arrest and resuscitation in the domestic pig显示文摘Cardiac arrest remains a leading cause of death and permanent disability worldwide. Although many victims are initially resuscitated, they often succumb to the extensive ischemia-reperfusion injury inflicted on the internal organs, especially the brain. Cardiac arrest initiates a complex cellular injury cascade encompassing reactive oxygen and nitrogen species, Ca2+ overload, ATP depletion, pro- and anti-apoptotic proteins, mitochondrial dysfunction, and neuronal glutamate excitotoxity, which injures and kills cells, compromises function of internal organs and ignites a destructive systemic inflammatory response. The sheer complexity and scope of this cascade challenges the development of experimental models of and effective treatments for cardiac arrest. Many experimental animal preparations have been developed to decipher the mechanisms of damage to vital internal organs following cardiac arrest and cardiopulmonary resuscitation(CPR), and to develop treatments to interrupt the lethal injury cascades. Porcine models of cardiac arrest and resuscitation offer several important advantages over other species, and outcomes in this large animal are readily translated to the clinical setting. This review summarizes porcine cardiac arrest-CPR models reported in the literature, describes clinically relevant phenomena observed during cardiac arrest and resuscitation in pigs, and discusses numerous methodological considerations in modeling cardiac arrest/CPR. Collectively, published reports show the domestic pig to be a suitable large animal model of cardiac arrest which is responsive to CPR, defibrillatory countershocks and medications, and yields extensive information to foster advances in clinical treatment of cardiac arrest. | Brandon H Cherry Anh Q Nguyen Roger A Hollrah Albert H Olivencia-Yurvati Robert T Mallet | 2015 | World Journal of Critical Care Medicine2015，4，1： | 2 |
