Inverse Association between Hepatitis B Virus Infection and Fatty Liver Disease: A Large-Scale Study in Populations Seeking for Check-Up
2013
Although many studies have attempted to clarify the association between hepatitis B virus (HBV) infection and fatty liver disease, no prior studies have emphasized the relationship of HBV and fatty liver regarding different demographics of age and body mass index (BMI).
To investigate the correlation of HBV and fatty liver in the different demographics of age and BMI.
We enrolled consecutive subjects who had received health check-up services at the Taipei Veterans General Hospital from 2002 to 2009 and ultrasonography was used to diagnose fatty liver according to the practice guidelines of the American Gastroenterological Association.
Among the 33,439 subjects enrolled in this study, fatty liver was diagnosed in 43.9% of the population and 38.9% of patients with chronic HBV infection. Multivariate analysis showed that BMI, age, waist circumference, systolic blood pressure, fasting glucose, cholesterol, alanine aminotransferase (ALT) levels, and platelet counts were positively associated, while hepatitis B surface antigen (HBsAg) positivity was inversely associated with fatty liver, especially for subjects with BMI>22.4 kg/m(2) and age>50 years. On the contrary, HBV infection was positively correlated with the presence of elevated serum ALT levels in subjects with fatty liver disease regardless of their age and BMI.
Metabolic factors are important determinants for the prevalence of fatty liver. Patients with HBV infection were inversely associated with fatty liver disease than the general population, especially in older and obese patients. Furthermore, metabolic factors and HBV infection were associated with elevated serum ALT levels in fatty liver disease.

Lower health literacy (HL) is associated with several cardiovascular disease (CVD) risk factors such as diabetes, hypertension, and metabolic syndrome (MS). The aim of our study was to investigate the association between HL and the Framingham 10-year risk score of CVD.
From 2015-2016, 1010 subjects aged 23 to 88 years receiving health check-up in Taipei Veterans General Hospital had complete clinical evaluations and laboratory examinations. Fatty liver was diagnosed by ultrasonography. The short form questionnaire adapted from the Mandarin Health Literacy Scale was used to assess HL. The Framingham risk score was calculated by patient characteristics.
Subjects with higher BMIs were associated with lower HL scores. The proportion of subjects with MS was higher in the lower health literacy score group (≤ 9) at 28.8%; further analysis found that lower HL was significantly associated with MS in women but not in men. The Spearman's rho demonstrated that the HL score was significantly associated with the BMI-based (rho = -0.11; P < 0.001) or lipid-based (rho = -0.09; P < 0.004) Framingham risk score.
Higher HL scores were associated with less CVD risk such as lower BMIs, less MS in women, and less fatty liver disease. Furthermore, HL had an inverse association with the Framingham risk score as expected. Therefore, HL in patients with CVD risk should be improved and considered as an important issue in terms of CVD reduction.

Background. Fatty liver index (FLI) and lipid accumulation product (LAP) are indexes originally designed to assess the risk of fatty liver and cardiovascular disease, respectively. Both indexes have been proven to be reliable markers of subsequent metabolic syndrome; however, their ability to predict metabolic syndrome in subjects without fatty liver disease has not been clarified. Methods. We enrolled consecutive subjects who received health check-up services at Taipei Veterans General Hospital from 2002 to 2009. Fatty liver disease was diagnosed by abdominal ultrasonography. The ability of the FLI and LAP to predict metabolic syndrome was assessed by analyzing the area under the receiver operating characteristic (AUROC) curve. Results. Male sex was strongly associated with metabolic syndrome, and the LAP and FLI were better than other variables to predict metabolic syndrome among the 29,797 subjects. Both indexes were also better than other variables to detect metabolic syndrome in subjects without fatty liver disease (AUROC: 0.871 and 0.879, resp.), and the predictive power was greater among women. Conclusion. Metabolic syndrome increases the cardiovascular disease risk. The FLI and LAP could be used to recognize the syndrome in both subjects with and without fatty liver disease who require lifestyle modifications and counseling.

Hepatoprotective and antioxidant effects of Wu-Zi-Yuan-Chung-Wan against CCl4-induced oxidative damage in rats
2021
This study was designed to investigate the hepatoprotective potentials of the Wu-Zi-Yuan-Chung-Wan (WZYCW) using an animal model of carbon tetrachloride (CCl4) induced liver injury. CCl4 induced chronic liver hepatotoxicity in adult Sprague-Dawley rats. Excluding the control group, all of the rats with chronic liver fibrosis received 0.4% CCl4 (1.5 mL/kg of body weight, ip) twice per week for 8 weeks. WZYCW (20, 100, and 500 mg/kg) and silymarin (200 mg/kg) were administered five times per week for 8 weeks. After 8 weeks, the rats were sacrificed, blood samples were obtained, and liver histological examinations were performed for subsequent assays. These results suggest that WZYCW considerably reduced Glutamic Oxaloacetic Transaminase (GOT), Glutamic Pyruvic Transaminase (GPT), Triglyceride (TG); and cholesterol activity; and the levels of malonaldehyde (MDA), nitric oxide (NO), and transforming growth factor-β1 (TGF-β1) in the liver. WZYCW also increased the level of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR) in liver tissue. WZYCW produced hepatoprotective and antifibrotic effects. This is the first study to demonstrate that WZYCW expressed hepatoprotective activity against CCl4 induced acute hepatotoxicity in rat. In addition, the primary compound of WZCYW was analyzed using HPLC. The major peaks of WZCYW, including schizandrin. The results indicate that WZYCW not only enhances hepatic antioxidant enzyme activities and inhibits lipid peroxidation but also suppresses inflammatory responses in CCl4 induced liver damage. Our findings provide evidence that WZYCW possesses a hepatoprotective activity to ameliorate chronic liver injury.

Experimental Investigations of Structural Responses of a High-Rise Building Subject to Oblique-Downstream Interference Effects
2026
This study experimentally investigates the aerodynamic mechanisms and dynamic responses of slender high-rise buildings subjected to oblique-downstream interference effects. Using a simulated open-terrain atmospheric boundary layer, a square prismatic principal building (aspect ratio 8.0) was evaluated alongside an identical interfering building. High-frequency force balance and aeroelastic vibration tests were conducted across four Scruton numbers (Scr). Aerodynamic damping was quantified using the random decrement technique and a trial-and-error approximation. Results show pronounced resonant amplification under strict conditions. Specifically, at a low Scr (1.12), a reduced velocity (Ur) of 5.5, and an interference location of x/B,y/B=−1.5, 1.5, the principal building exhibits an inclined elliptical trajectory, driven by a negative aerodynamic damping effect of approximately −2%. Higher Scr values attenuate displacement, but rooftop acceleration amplifications persist, reaching an interference factor of 2.0. Ultimately, the synchronized rhythmic channeling required to excite the principal building necessitates a minimum wake width from the interfering structure (breadth-to-depth ratio > 0.5), highlighting critical aeroelastic instabilities in dense high-rise clusters.

We previously demonstrated that B1 induced significant cytotoxic effects, cell cycle G1 arrest and apoptosis in human lung cancer A549 cells through the inhibition of DNA topoisomerase II activity. In the present study, we focused on the histone deacetylase (HDAC) modulation of B1 in A549 cells. HDACs, important enzymes affecting epigenetic regulation, play a crucial role in human carcinogenesis. Our findings showed that B1 could suppress the growth of A549 cells in vitro through the inhibition of HDAC activity. Additionally, B1 caused disruption of the mitochondrial membrane potential and induced DNA double-strand breaks (DSBs) in a dose- and time-dependent manner, which consequently led to cell apoptosis. We also observed that B1 inhibited cancer cell migration and angiogenesis-related signal expression, including vascular endothelial growth factor (VEGF) and pro-matrix metalloproteinases-2 and -9 (pro-MMP-2/9). Gelatin zymography suggested that B1 decreased pro-MMP-2 and pro-MMP-9 activity. Transcription factors, signal transducer and activator of transcription 3 (STAT3) and nuclear factor-κB (NF-κB), are vital players in the many steps of carcinogenesis. B1 showed significant dose-response inhibitory effects on cytoplasmic expression and nuclear translocation of both phosphorylated STAT3 (pSTAT3) and NF-κB. It has been well documented that reactivated telomerase confers cancer cells the ability to repair DNA. Real-time PCR results indicated that B1 inhibited STAT3 and NF-κB mRNA expression and telomerase activity. Taken together, our results demonstrated that B1 exerted significant inhibitory effects on HDAC, telomerase activities, oncogenic STAT3 and NF-κB expression. The inhibition of the intricate crosstalk between STAT3 and NF-κB may be a major factor in the molecular action mechanism of B1. The multiple targeting effects of B1 render it a potential new drug for lung cancer therapy.
