| 1 | Mechanisms underlying feed intolerance in the critically ill: Implications for treatment显示文摘Malnutrition is associated with poor outcomes in critically ill patients. Although nutritional support is yet to be proven to improve mortality in non-malnourished critically ill patients, early enteral feeding is considered best practice. However, enteral feeding is often limited by delayed gastric emptying. The best method to clinically identify delayed gastric emptying and feed intolerance is unclear. Gastric residual volume (GRV) measured at the bedside is widely used as a surrogate marker for gastric emptying, but the value of GRV measurement has recently been disputed. While the mechanisms underlying delayed gastric emptying require further investigation, recent research has given a better appreciation of the pathophysiology. A number of pharmacological strategies are available to improve the success of feeding. Recent data suggest a combination of intravenous metoclopramide and erythromycin to be the most successful treatment, but novel drug therapies should be explored. Simpler methods to access the duodenum and more distal small bowel for feed delivery are also under investigation. This review summarises current understanding of the factors responsible for, and mechanisms underlying feed intolerance in critical illness, together with the evidence for current practices. Areas requiring further research are also highlighted. | Adam Deane Marianne J Chapman Robert J Fraser Laura K Bryant Carly Burgstad Nam Q Nguyen | 2007 | World Journal of Gastroenterology2007，13，29： | 18 |
| 2 | 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 |
| 3 | 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 | Counter-regulatory phosphatases TNAP and NPP1 temporally regulate tooth root cementogenesis显示文摘Cementum is critical for anchoring the insertion of periodontal ligament fibers to the tooth root. Several aspects of cementogenesis remain unclear, including differences between acellular cementum and cellular cementum, and between cementum and bone.Biomineralization is regulated by the ratio of inorganic phosphate(Pi) to mineral inhibitor pyrophosphate(PPi), where local Piand PPi concentrations are controlled by phosphatases including tissue-nonspecific alkaline phosphatase(TNAP) and ectonucleotide pyrophosphatase/phosphodiesterase 1(NPP1). The focus of this study was to define the roles of these phosphatases in cementogenesis. TNAP was associated with earliest cementoblasts near forming acellular and cellular cementum. With loss of TNAP in the Alpl null mouse, acellular cementum was inhibited, while cellular cementum production increased, albeit as hypomineralized cementoid. In contrast, NPP1 was detected in cementoblasts after acellular cementum formation, and at low levels around cellular cementum. Loss of NPP1 in the Enpp1 null mouse increased acellular cementum, with little effect on cellular cementum.Developmental patterns were recapitulated in a mouse model for acellular cementum regeneration, with early TNAP expression and later NPP1 expression. In vitro, cementoblasts expressed Alpl gene/protein early, whereas Enpp1 gene/protein expression was significantly induced only under mineralization conditions. These patterns were confirmed in human teeth, including widespread TNAP, and NPP1 restricted to cementoblasts lining acellular cementum. These studies suggest that early TNAP expression creates a low PPienvironment promoting acellular cementum initiation, while later NPP1 expression increases PPi, restricting acellular cementum apposition. Alterations in PPihave little effect on cellular cementum formation, though matrix mineralization is affected. | Laura E Zweifler Mudita K Patel Francisco H Nociti Jr Helen F Wimer Jose L Milln Martha J Somerman Brian L Foster | 2015 | International Journal of Oral Science2015，7，1： | 5 |
| 5 | Intravenous immune globulin suppresses angiogenesis in mice and humans显示文摘Human intravenous immune globulin(IVIg),a purified IgG fraction composed of~60%IgG1 and obtained from the pooled plasma of thousands of donors,is clinically used for a wide range of diseases.The biological actions of IVIg are incompletely understood and have been attributed both to the polyclonal antibodies therein and also to their IgG(IgG)Fc regions.Recently,we demonstrated that multiple therapeutic human IgG1 antibodies suppress angiogenesis in a target-independent manner via FcγRI,a high-affinity receptor for IgG1.Here we show that IVIg possesses similar anti-angiogenic activity and inhibited blood vessel growth in five different mouse models of prevalent human diseases,namely,neovascular age-related macular degeneration,corneal neovascularization,colorectal cancer,fibrosarcoma and peripheral arterial ischemic disease.Angioinhibition was mediated by the Fc region of IVIg,required FcγRI and had similar potency in transgenic mice expressing human FcγRs.Finally,IVIg therapy administered to humans for the treatment of inflammatory or autoimmune diseases reduced kidney and muscle blood vessel densities.These data place IVIg,an agent approved by the US Food and Drug Administration,as a novel angioinhibitory drug in doses that are currently administered in the clinical setting.In addition,they raise the possibility of an unintended effect of IVIg on blood vessels. | Reo Yasuma Valeria Cicatiello Takeshi Mizutani Laura Tudisco Younghee Kim Valeria Tarallo Sasha Bogdanovich Yoshio Hirano Nagaraj Kerur Shengjian Li Tetsuhiro Yasuma Benjamin J Fowler Charles B Wright Ivana Apicella Adelaide Greco Arturo Brunetti Balamurali K Ambati Sevim Barbasso Helmers Ingrid E Lundberg Ondrej Viklicky Jeanette HW Leusen J Sjef Verbeek Bradley D Gelfand Ana Bastos-Carvalho Sandro De Falco Jayakrishna Ambati | 2016 | Signal Transduction and Targeted Therapy2016，1，1： | 3 |

| 8 | Proximal gastric motility in critically ill patients with type 2 diabetes mellitus显示文摘AIM: To investigate the proximal gastric motor response to duodenal nutrients in critically ill patients with long- standing type 2 diabetes mellitus. METHODS: Proximal gastric motility was assessed (using a barostat) in 10 critically ill patients with type 2 diabetes mellitus (59 ± 3 years) during two 60-min duodenal infusions of Ensure? (1 and 2 kcal/min), in random order, separated by 2 h fasting. Data were compared with 15 non-diabetic critically ill patients (48 ± 5 years) and 10 healthy volunteers (28 ± 3 years). RESULTS: Baseline proximal gastric volumes were similar between the three groups. In diabetic patients, proximal gastric relaxation during 1 kcal/min nutrient infusion was similar to non-diabetic patients and healthy controls. In contrast, relaxation during 2 kcal/ min infusion was initially reduced in diabetic patients (P < 0.05) but increased to a level similar to healthy humans, unlike non-diabetic patients where relaxation was impaired throughout the infusion. Duodenal nutrient stimulation reduced the fundic wave frequency in a dose-dependent fashion in both the critically ill diabetic patients and healthy subjects, but not in critically ill patients without diabetes. Fundic wave frequency in diabetic patients and healthy subjects was greater than in non-diabetic patients. CONCLUSION: In patients with diabetes mellitus, proximal gastric motility is less disturbed than non- diabetic patients during critical illness, suggesting that these patients may not be at greater risk of delayed gastric emptying. | Nam Q Nguyen Robert J Fraser Laura K Bryant Marianne Chapman Richard H Holloway | 2007 | World Journal of Gastroenterology2007，13，2： | 3 |
