Circulating metabolites are associated with persistent elevations of ALT in patients with chronic hepatitis B with complete viral suppression

Dekai Zheng, Changhao Cheng, Yanhua Tang, Zhixin Fang, more

Journal of Medical Virology > 96 > 6 > n/a - n/a

Hepatitis B virus (HBV) can be completely suppressed after antiviral treatment; however, some patients with chronic hepatitis B (CHB) exhibit elevated alanine aminotransferase (ALT) levels and sustained disease progression. This study provides novel insights into the mechanism and potential predictive biomarkers of persistently elevated ALT (PeALT) in patients with CHB after complete viral inhibition...

Impact of nonalcoholic fatty liver disease status change on antiviral efficacy of nucleos(t)ide analogues in HBeAg‐positive chronic hepatitis B

Yanhua Tang, Rong Fan, Zhixian Lan, Qing Xie, more

Journal of Medical Virology > 95 > 2 > n/a - n/a

Data on the dynamic changes in chronic hepatitis B (CHB) patients with nonalcoholic fatty liver disease (NAFLD) during antiviral therapy are scarce. We aimed to investigate the evolution of NAFLD status change in CHB patients treated with nucleos(t)ide analogues (NAs) and its influence on therapeutic outcomes. This retrospective study included 164 HBeAg‐positive CHB patients from a randomized controlled...

Blockage of PD‐L1 by FERMT3‐mediated Wnt/β‐catenin signalling regulates chemoresistance and immune evasion of colorectal cancer cells

Yanhua Tang, Nan Nan, Chuanzhi Gui, Xuan Zhou, more

Clinical and Experimental Pharmacology and Physiology > 49 > 9 > 988 - 997

Colorectal cancer (CRC) constitutes a major public health problem because of the high rate of morbidity and mortality. Chemotherapy and immunotherapy are the major and promising strategies for cancer patients including CRC; nevertheless, chemoresistance and immune escape limit the final efficacy of the above approaches. FERMT3 has proven to exert a critical role in the immune system and has contradictive...

FGF23 regulates atrial fibrosis in atrial fibrillation by mediating the STAT3 and SMAD3 pathways

Quanbin Dong, Shaochuan Li, Weixue Wang, Lu Han, more

Journal of Cellular Physiology > 234 > 11 > 19502 - 19510

High fibroblast growth factor 23 (FGF23) concentrations are a strong predictor of atrial fibrillation (AF), but researchers have not clearly determined the mechanism by which FGF23 causes atrial fibrosis in patients with AF. This study aims to elucidate the mechanism by which FGF23 induces atrial fibrosis in patients with AF. Immunohistochemistry was used to study the expression of FGF23, FGFR4, and...

Quantitative comparison of MR diffusion‐weighted imaging for liver focal lesions between 3.0T and 1.5T: Regions of interest of the minimum‐spot ADC, the largest possible solid part, and the maximum diameter in lesions

Yanhua Tang, Haiyi Wang, Yingwei Wang, Jie Li, more

Journal of Magnetic Resonance Imaging > 44 > 5 > 1320 - 1329

Purpose To quantitatively compare the apparent diffusion coefficient (ADC) values of 3.0T and 1.5T magnetic resonance (MR) diffusion‐weighted imaging (DWI) protocols using regions of interest (ROIs) for the minimum ADC, largest solid part, and maximum diameter of lesions, for the detection of liver focal lesions. Materials and Methods In total, 26 patients with 28 liver focal lesions prospectively...

Dimensional Synthesis and Analysis of the 2-UPS-PU Parallel Manipulator

Yunfeng Zhao, Yanhua Tang, Yongsheng Zhao

Lecture Notes in Computer Science > Intelligent Robotics and Applications > Robot Motion Planning and Manipulation > 141-151

A new 2-UPS-PU parallel manipulator with one translational and two rotational degrees of freedom (DOF) has been proposed in this paper, which has the advantages of high rotational capability and high load carrying capacity, etc. The mobility of the robot is analyzed. The inverse and forward kinematics problems are solved. The velocity and force Jacobian of the new parallel manipulator are given. An...

Diffusion-weighted imaging of hepatocellular carcinomas: a retrospective analysis of correlation between apparent diffusion coefficients and histological grade

Yanhua Tang, Haiyi Wang, Lu Ma, Xiaojing Zhang, more

Abdominal Radiology > 2016 > 41 > 8 > 1539-1545

Purpose To define correlations between the pathological grades of hepatocellular carcinomas (HCCs) and apparent diffusion coefficients (ADCs) derived using breath-holding diffusion-weighted imaging (BH-DWI). Methods We retrospectively evaluated 94 patients (105 lesions) with pathologically proved HCC who underwent hepatic DWI on a 3.0-T MR platform. HCCs were divided into five groups: well-differentiated...

Adaptive-fuzzy sliding-mode control for the attitude system of a quadrotor

Yanhua Tang, Hongbin Zhang, Junjie Gong

2015 Chinese Automation Congress (CAC) > 1075 - 1079

2015 Chinese Automation Congress (CAC)

Adaptive-fuzzy control has been shown to be an effective control approach for robustness of nonlinear systems. Sliding-mode control has fast response and insensitive to some class of uncertainty. The attitude system of the quadrotor determines its trajectory and the system is nonlinear, multi-variable, and coupled. In this paper, an adaptive-fuzzy sliding-mode controller is designed for the attitude...

Research on the Relationship between Classic Denavit-Hartenberg and Modified Denavit-Hartenberg

Hang Wang, Hanghang Qi, Minghui Xu, Yanhua Tang, more

2014 Seventh International Symposium on Computational Intelligence and Design > 2 > 26 - 29

2014 7th International Symposium on Computational Intelligence and Design (ISCID)

Currently, homogeneous transformation method has been widely used for its advantages in robot. Its more commonly used modeling methods are classic Denavit-Hartenberg method and modified Denavit-Hartenberg method, but the relationship between the two is very few devoted. Then, the use area is limited. Therefore, the relationship between classic Denavit-Hartenberg method and modified Denavit-Hartenberg...

Absence of detectable viremia in a perinatally HIV-1–infected teenager after discontinuation of antiretroviral therapy

Margaret E. Feeney, Yanhua Tang, Almas Rathod, Catherine Kneut, more

The Journal of Allergy and Clinical Immunology > 2006 > 118 > 2 > 324-330

A 15-year-old girl with perinatal HIV-1 infection has remained asymptomatic with undetectable plasma HIV-1 viremia for more than 5 years after discontinuing all antiretroviral therapy. Viral sequence analysis of proviral HIV-1 DNA revealed no evident fitness-attenuating deletions or mutations. This subject exhibited an unusually robust HIV-specific T-cell response, with an intact CD4 ⁺ T cell–proliferative...

Mother-to-child transmission of HIV infection and CTL escape through HLA-A2-SLYNTVATL epitope sequence variation

Philip J.R. Goulder, Christophe Pasquier, Eddie C. Holmes, Bin Liang, more

Immunology Letters > 2001 > 79 > 1-2 > 109 - 116

Cytotoxic T lymphocytes (CTL) play a central role in containment of HIV infection. Evasion of the immune response by CTL escape is associated with progression to disease. It is therefore hypothesised that transmitted viruses encode escape mutations within epitopes that are required for successful control of viraemia. In order to test this hypothesis, escape through the dominant HLA-A2-restricted CTL...
