2Viral and host causes of fatty liver in chronic hepatitis B显示文摘AIM: To investigate the viral and host causes of fatty liver in chronic hepatitis B patients and the role of fat deposits in liver damage.METHODS: A total of 164 patients (113 males and 51 females, average age 35±11.3 years, and range 10-62 years) with previously untreated chronic hepatitis B were included in the study. The patients were divided into two groups depending on the result of liver biopsy: group without steatosis (100 patients with <5% hepatosteatosis) and group with steatosis (64 patients with >5% hepatosteatosis). The groups were compared in terms of gender, body mass index (BMI), liver enzymes (ALT, AST, ALP, GGT), cholesterol, triglyceride, HBeAg, viral load, and histological findings. In the group with steatosis, the patients were subdivided depending on the degree of steatosis into mild group (45 patients with 5-24% steatosis), and severe group (19 patients with >25% steatosis). RESULTS: In the group of chronic hepatitis B with steatosis, the mean age, BMI, cholesterol, and triglyceride levels were significantly higher than those in the group without steatosis (P<0.05). Steatosis was found in 53 (46.9%) of male patients and 11 (22%) of female patients (P<0.05). No significant difference was found in the positivity of ALT, AST, ALP, GGT, HBeAg, viral load, histological activity index (HAI) and stage between the two groups (P>0.05). In the group with severe steatosis, the BMI was significantly higher than that in the group with mild steatosis (P<0.05). No significant difference was found in the other parameters between the groups (P>0.05). CONCLUSION: Steatosis in chronic hepatitis B appears to be a result of metabolic factors of the host rather than the effect of viruses. Steatosis is unrelated to the HAI and degree of fibrosis, which are considered as the histological indicators of liver damage.Emin Altiparmak Seyfettin K(o|¨)klü Mesut Yalinkilic Osman Yüksel Bahattin Cicek Ertugrul Kayacetin Tülin Sahin 2005World Journal of Gastroenterology2005,11,20:52

4Comparative evaluation of intragastric bile acids and hepatobiliary scintigraphy in the diagnosis of duodenogastric reflux显示文摘AIM:To assess the diagnostic value of a combination of intragastric bile acids and hepatobiliary scintigraphy in the detection of duodenogastric reflux(DGR).METHODS:The study contained 99 patients with DGR and 70 healthy volunteers who made up the control group.The diagnosis was based on the combination of several objective arguments:a long history of gastric symptoms(i.e.,nausea,epigastric pain,and/or bilious vomiting) poorly responsive to medical treatment,gastroesophageal reflux symptoms unresponsive to protonpump inhibitors,gastritis on upper gastrointestinal(GI) endoscopy and/or at histology,presence of a bilious gastric lake at > 1 upper GI endoscopy,pathologic 24-h intragastric bile monitoring with the Bilitec device.Gas-tric juice was aspirated in the GI endoscopy and total bile acid(TBA),total bilirubin(TBIL) and direct bilirubin(DBIL) were tested in the clinical laboratory.Continuous data of gastric juice were compared between each group using the independent-samples Mann-Whitney U-test and their relationship was analysed by Spearman's rank correlation test and Fisher's linear discriminant analysis.Histopathology of DGR patients and 23 patients with chronic atrophic gastritis was compared by clinical pathologists.Using the Independent-samples Mann-Whitney U-test,DGR index(DGRi) was calculated in 28 patients of DGR group and 19 persons of control group who were subjected to hepatobiliary scintigraphy.Receiver operating characteristic curve was made to determine the sensitivity and specificity of these two methods in the diagnosis of DGR.RESULTS:The group of patients with DGR showed a statistically higher prevalence of epigastric pain in comparison with control group.There was no significant difference between the histology of gastric mucosa with atrophic gastritis and duodenogastric reflux.The bile acid levels of DGR patients were significantly higher than the control values(Z:TBA:-8.916,DBIL:-3.914,TBIL:-6.197,all P < 0.001).Two of three in the DGR group have a significantly associated with each other(r:TBA/DBIL:0.362,TBA/TBIL:0.470,DBIL/TBIL:0.737,all P < 0.001).The Fisher's discriminant function is followed:Con:Y = 0.002TBA + 0.048DBIL + 0.032TBIL 0.986;Reflux:Y = 0.012TBA + 0.076DBIL + 0.089TBIL-2.614.Eighty-four point zero five percent of original grouped cases were correctly classified by this method.With respect to the DGR group,DGRi were higher than those in the control group with statistically significant differences(Z =-5.224,P < 0.001).Twenty eight patients(59.6%) were deemed to be duodenogastric reflux positive by endoscopy,as compared to 37 patients(78.7%) by hepatobiliary scintigraphy.CONCLUSION:The integrated use of intragastric bile acid examination and scintigraphy can greatly improve the sensitivity and specificity of the diagnosis of DGR.Teng-Fei Chen Praveen K Yadav Rui-Jin Wu Wei-Hua Yu Chang-Qin Liu Hui Lin Zhan-Ju Liu 2013World Journal of Gastroenterology2013,19,14:12
5Repeatability and Reproducibility of Quantitative Assessment of the Retinal Microvasculature Using Optical Coherence Tomography Angiography Based on Optical Microangiography显示文摘Objective The aim of this study was to determine the repeatability and reproducibility of optical coherence tomography angiography(OCTA) based on optical microangiography(OMAG) measurements of macular vessels in normal eyes. Methods In this prospective cohort study, 40 eyes of 40 healthy volunteers underwent repeated OCTA(Cirrus HD-OCT 5000 angiography system, Carl Zeiss Meditec, Inc.) scans on two separate visit days. On each visit day, the eyes were scanned three times. The following parameters were used to quantitatively describe the OCTA images of the superficial vascular network: vessel area density(VAD), vessel skeleton density(VSD), vessel diameter index(VDI), vessel perimeter index(VPI), vessel complexity index(VCI), flux, and foveal avascular zone(FAZ). Coefficient of variation(CV) and intraclass correlation coefficient(ICC) were calculated for evaluating intravisit and intervisit repeatability, as well as interobserver reproducibility. Results The measurements showed high repeatability [CVs ≤ 4.2%(intravisit) and ≤ 4.6%(intervisit)] and interobserver reproducibility(ICCs ≥ 0.923) for all parameters. Conclusion This study demonstrated good repeatability and reproducibility of OCTA based on OMAG for the measurement of superficial vessel parameters in normal eyes.ZHAO Qi YANG Wen Li WANG Xiao Na Ruikang K Wang YOU Qi Sheng CHU Zhong Di XIN Chen ZHANG Meng Yu LI Dong Jun WANG Zi Yang CHEN Wei LI Yi Feng CUI Rui SHEN Lin WEI Wen Bin 2018Biomedical and Environmental Sciences2018,31,6:8
