| 1 | Combined acoustic radiation force impulse, aminotransferase to platelet ratio index and Forns index assessment for hepatic fibrosis grading in hepatitis B显示文摘AIM: To investigate the combined diagnostic accuracy of acoustic radiation force impulse(ARFI), aspartate aminotransferase to platelet ratio index(APRI) and Forns index for a non-invasive assessment of liver fibrosis in patients with chronic hepatitis B(CHB). METHODS: In this prospective study, 206 patients had CHB with liver fibrosis stages F0-F4 classified by METAVIR and 40 were healthy volunteers were measured by ARFI, APRI and Forns index separately or combined as indicated. RESULTS: ARFI, APRI or Forns index demonstrated a significant correlation with the histological stage(all P < 0.001). According to the AUROC of ARFI and APRI for evaluating fibrotic stages more than F2, ARFI showed an enhanced diagnostic accuracy than APRI(P < 0.05). The combined measurement of ARFI and APRI exhibited better accuracy than ARFI alone when evaluating ≥ F2 fibrotic stage(Z = 2.77, P = 0.006). Combination of ARFI, APRI and Forns index did not obviously improve the diagnostic accuracy compared to the combination of ARFI and APRI(Z = 0.958, P = 0.338). CONCLUSION: ARFI + APRI showed enhanced diagnostic accuracy than ARFI or APRI alone for significant liver fibrosis and ARFI + APRI + Forns index shows the same effect with ARFI + APRI. | Chang-Feng Dong Jia Xiao Ling-Bo Shan Han-Ying Li Yong-Jia Xiong Gui-Lin Yang Jing Liu Si-Min Yao Sha-Xi Li Xiao-Hua Le Jing Yuan Bo-Ping Zhou George L Tipoe Ying-Xia Liu | 2016 | World Journal of Hepatology2016,8,14: | 18 |
| 2 | Beneficial mechanisms of aerobic exercise on hepatic lipid metabolism in non-alcoholic fatty liver disease显示文摘BACKGROUND:Non-alcoholic fatty liver disease(NAFLD)refers to any fatty liver disease that is not due to excessive use of alcohol.NAFLD probably results from abnormal hepatic lipid metabolism and insulin resistance.Aerobic exercise is shown to improve NAFLD.This review aimed to evaluate the molecular mechanisms involved in the beneficial effects of aerobic exercise on NAFLD.DATA SOURCE:We searched articles in English on the role of aerobic exercise in NAFLD therapy in Pub Med. | Rui Guo Emily C Liong Kwok Fai So Man-Lung Fung George L Tipoe | 2015 | Hepatobiliary & Pancreatic Diseases International2015,14,2: | 16 |
| 3 | Therapeutic approaches to non-alcoholic fatty liver disease: past achievements and future challenges显示文摘BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver injury and mortality in Western countries and China. However, as to date, there is no direct and effective therapy for this disease. The aim of this review is to analyze the key progress and challenges of main current therapeutic approaches in NAFLD. DATA SOURCE: We carried out a PubMed search of English-language articles relevant to NAFLD therapy. RESULTS: There are two major therapeutic strategies for NAFLD treatment: (1) lifestyle interventions (including weight reduction, dietary modification and physical exercise) and (2) pharmaceutical therapies. Lifestyle interventions, particularly chronic and moderate intensity exercise, are the most effective and recognized clinical therapies for NAFLD. For pharmaceutical therapies, although their effects and mechanisms have been extensively investigated in laboratory studies, they still need further tests and investigations in clinical human trials. CONCLUSION: Future advancement of NAFLD therapy should focus on the mechanistic studies on cell based and animal models and human clinical trials of exercise, as well as the combination of lifestyle intervention and pharmaceutical therapy specifically targeting main signaling pathways related to lipid metabolism, oxidative stress and inflammation. | Jia Xiao Rui Guo Man Lung Fung Emily C Liong George L Tipoe | 2013 | Hepatobiliary & Pancreatic Diseases International2013,12,2: | 14 |
