| 1 | Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered. | Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López | 2014 | World Journal of Radiology2014，6，6： | 30 |
| 2 | Different patterns of intestinal response to injury after arterial,venous or arteriovenous occlusion in rats显示文摘AIM:To investigate the differences in injury patterns caused by arterial, venous or arteriovenous mesenteric occlusion.METHODS: Male Wistar rats were separated equally into four groups. Occlusion was performed by clamping the superior mesenteric artery (A), the mesenteric vein (V) or both (AV) for 30 min, followed by 60 min of reperfusion. A control group received sham surgery only. Intestinal sections were examined for histological damage and serum tumor necrosis factor-α (TNF-α), endothelin-1 (ET-1), P-selectin, antithrombin (AT) and soluble intracellular adhesion molecule-1(ICAM-1) concentrations were measured. RESULTS: All groups showed signif icant mucosal injury compared to controls. Furthermore, mucosal injury was significantly more severe in the V and AV groupscompared to the A group (3.6±0.55, 3.4±0.55 and 2±0.71, respectively, P=0.01). ICAM-1 was similarly elevated in all groups, with no significant differences between the groups. P-selectin levels were significantly elevated in the V and AV groups but not the A group (1.4±0.5 ng/mL, 2.52±0.9 ng/mL and 0.02±0.01 ng/mL, respectively, P=0.01) and ET-1 was significantly elevated in the A and V groups but not the AV group (0.32±0.04 pg/mL, 0.36±0.05 pg/mL and 0.29±0.03 pg/mL, respectively, P=0.01) compared to sham controls. AT CONCLUSION:Different patterns of response to ischemia/reperfusion are associated with venous, arterial or arteriovenous occlusion. Venous and arteriovenous occlusion was associated with the most severe alterations. | Francisco Javier Guzmán-de la Garza Carlos Rodrigo Cámara-Lemarroy Gabriela Alarcón-Galván Paula Cordero-Pérez Linda Elsa Muoz-Espinosa Nancy Esthela Fernández-Garza | 2009 | World Journal of Gastroenterology2009，15，31： | 10 |
| 3 | Metabolic complications in liver transplant recipients显示文摘The metabolic syndrome(MS), which includes obesity,dyslipidaemia, hypertension and hyperglycaemia according to the most widely accepted definitions now used, is one of the most common post-transplant complications, with a prevalence of 44%-58%. The MS, together with the immunosuppression, is considered the main risk factor for the development of cardiovascular disease(CVD) in transplant recipients, which in turn accounts for 19%-42% of all deaths unrelated to the graft. The presence of MS represents a relative risk for the development of CVD and death of 1.78. On the other hand, non-alcoholic fatty liver disease(NAFLD), considered as the manifestation of the MS in the liver, is now the second leading reason for liver transplantation in the United States after hepatitis C and alcohol. NAFLD has a high rate of recurrence in the liver graft and a direct relation with the worsening of other metabolic disorders, such as insulin resistance or diabetes mellitus. Consequently, it is vitally important to identify and treat as soon as possible such modifiable factors as hypertension, overweight, hyperlipidaemia or diabetes in transplanted patients to thus minimise the impact on patient survival. Additionally, steroid-free regimens are favoured, with minimal immunosuppression to limit the possible effects on the development of the MS. | Miguel Jiménez-Pérez Rocío González-Grande Edith Omonte Guzmán Víctor Amo Trillo Juan Miguel Rodrigo López | 2016 | World Journal of Gastroenterology2016，22，28： | 10 |
| 4 | Reduction of the closure time of postoperative enterocutaneous fistulas with fibrin sealant显示文摘AIM: To assess whether the use of fibrin sealantshortens the closure time of postoperative enterocutaneous fistulas (ECFs). METHODS: The prospective case-control study included 70 patients with postoperative ECFs with an output of < 500 mL/d, a fistulous tract of > 2 cm and without any local complication. They were divided into study (n = 23) and control groups (n = 47). Esophageal, gastric and colocutaneous fistulas were monitored under endoscopic visualization, which also allowed fibrin glue application directly through the external hole. Outcome variables included closure time, time to resume oral feeding and morbidity related to nutritional support. RESULTS: There were no differences in mean age, fistula output, and follow-up. Closure-time for all patients of the study group was 12.5 ± 14.2 d and 32.5 ± 17.9 d for the control group (P < 0.001), and morbidity related to nutritional support was 8.6% and 42.5%, respectively (P < 0.01). In patients with colonic fistulas, complete closure occurred 23.5 ± 19.5 d after the first application of fibrin glue, and spontaneous closure was observed after 36.2 ± 22.8 d in the control group (P = 0.36). Recurrences were observed in 2 patients because of residual disease. One patient of each group died during follow-up as a consequence of septic complications related to parenteral nutrition. CONCLUSION: Closure time was significantly reduced with the use of fibrin sealant, and oral feeding was resumed faster. We suggest the use of fibrin sealant for the management of stable enterocutaneous fistulas. | Jorge Avalos-González Eliseo Portilla-deBuen Caridad Aurea Leal-Cortés Abel Orozco-Mosqueda María del Carmen Estrada-Aguilar Gabriela Abigail Velázquez-Ramírez Gabriela Ambriz-González Clotilde Fuentes-Orozco Aldo Emmerson Guzmán-Gurrola Alejandro González-Ojeda | 2010 | World Journal of Gastroenterology2010，16，22： | 10 |
| 5 | Ketamine anesthesia reduces intestinal ischemia/reperfusion injury in rats显示文摘AIM: To investigate the effects of ketamine anesthesia on the motility alterations and tissue injury caused by ischemia/reperfusion in rats. METHODS: Thirty male Wistar rats weighing 200-250 g were used. Ischemia was induced by ob-structing blood flow in 25% of the total small intesti-nal length (ileum) with a vascular clamp for 45 min, after which either 60 min or 24 h of reperfusion was allowed. Rats were either anesthetized with pento-barbital sodium (50 mg/kg) or ketamine (100 mg/kg). Control groups received sham surgery. After 60 min of reperfusion, the intestine was examined for mor-phological alterations, and after 24 h intestinal basic electrical rhythm (BER) frequency was calculated, and intestinal transit determined in all groups. RESULTS: The intestinal mucosa in rats that were anesthetized with ketamine showed moderate altera-tions such as epithelial lifting, while ulceration and hemorrhage was observed in rats that received pento-barbital sodium after 60 min of reperfusion. Quantita-tive analysis of structural damage using the Chiu scaleshowed significantly less injury in rats that received ketamine than in rats that did not (2.35 ± 1.14 vs 4.58 ± 0.50, P < 0.0001). The distance traveled by a mark-er, expressed as percentage of total intestinal length, in rats that received pentobarbital sodium was 20% ± 2% in comparison with 25.9% ± 1.64% in rats that re-ceived ketamine (P = 0.017). BER was not statistically different between groups. CONCLUSION: Our results show that ketamine anesthesia is associated with diminished intestinal injury and abolishes the intestinal transit delay induced by ischemia/reperfusion. | Carlos Rodrigo Cámara Francisco Javier Guzmán Ernesto Alexis Barrera Andrés Jesús Cabello Armando Garcia Nancy Esthela Fernández Eloy Caballero Jesus Ancer | 2008 | World Journal of Gastroenterology2008，14，33： | 5 |

| 7 | Ag-Zn粉末的机械合金化和随后的热处理(英文)显示文摘研究了在机械合金化过程中Ag和Zn以及随后的热处理中的显微组织演变。机械合金化在SPEX8000D铣床中进行。采用X射线衍射(XRD)﹑透射电子显微镜(TEM)和扫描电子显微镜(SEM)观察样品的显微组织。使用差示扫描量热计(DSC)研究样品的热性能。结果表明,在合金化初期的碾磨过程中能观察到ε,β,β′,α固溶体和剩余的Zn。随后,ε,β,β′和Zn相消失,α固溶体中的Zn浓度剧烈升高。在碾磨7.2ks后,机械合金化过程达到稳定状态。在此期间,α固溶体的组分和晶粒尺寸保持不变。后续热处理表明α固溶体也能够通过机械合金化结合热处理得到。最后,为了得到α固溶体,根据碾磨和热处理过程中样品的微观组织演变,提出一个最佳的工艺路线。 | Danny GUZMN Oscar RIVERA Claudio AGUILAR Stella ORDOEZ Carola MARTíNEZ Daniel SERAFINI Paula ROJAS | 2013 | Transactions of Nonferrous Metals Society of China2013，23，7： | 2 |
