The World Health Organization set a goal to eliminate viral hepatitis as a public health threat by 2030. However, achieving this goal appears challenging due to the current low rates of diagnosis and treatment.
View Article and Find Full Text PDFFatty acids (FA) are an important factor affecting meat quality and human health, and the important role of the solute carrier family 27 member 6 (SLC27A6) in FA metabolism has been demonstrated in several species. However, the expression profile of the SLC27A6 in different tissues and the effect of its polymorphism on FA in sheep are currently unknown. This study aimed to explore the differences in FAs in the longissimus dorsi (LD) of 1,085 Hu sheep, the expression profile of SLC27A6, and confirm the effect of single nucleotide polymorphisms (SNPs) on FA phenotypes.

Nitric oxide (NO) and brassinolides (BR) are plant growth regulators that coordinate a plethora of plant physiological responses. Nonetheless, the way in which these factors interact to affect salt tolerance is not well understood.

Research Design And Methods: We conducted a prospective cohort study involving 11,457 singleton pregnant women without preexisting diabetes from the Beijing Birth Cohort Study, along with their neonates born between July 2021 and October 2022 in Beijing, China. Distinct maternal glucose trajectories were identified using a latent class model based on blood glucose levels across the three trimesters, and their association with neonatal circulating metabolites, including 11 amino acids and 33 acylcarnitines, was examined, adjusting for potential confounding factors.
Transcatheter aortic valve replacement (TAVR) has emerged as an effective therapy for inoperable patients with severe aortic stenosis (AS). However, calcification-induced limited durability restricts its application. Fish swim bladders (FSB), which are resistant to calcific degeneration, offer a viable solution to this challenge.

However, the difference of fibrosis regression rates in short-term and long-term antiviral therapy remain unclear. Therefore, we aimed to identify the dynamic changes in fibrosis regression rate in patients with three-time liver biopsies during 5 years antiviral therapy.

Ferroptosis is an iron-dependent form of regulated cell death and is characterized by high concentrations of intracellular lipid peroxide and a redox imbalance in the cells. Ferroptosis shows distinct morphological and biological features compared with other prominent mechanisms of programmed cell death. The distinct characteristics of ferroptosis include the dysfunction of the lipid peroxide repair enzyme glutathione peroxidase 4, the presence of ferrous iron overload, and the lipid peroxidation of polyunsaturated fatty acids.

In this study, we validated and compared the utility of the RECAM and RUCAM in Chinese patients with a single conventional or herbal agent-induced liver injury.
Methods: In this retrospective multicenter cohort of well-established DILI and non-DILI patients from 5 centers in China, the diagnostic performance of the RUCAM and RECAM was compared by AUC analysis.
Because substantial numbers of Chinese consumers are prepared to pay for tender and quality lamb, meat quality traits are becoming more relevant for breeding programs for Chinese sheep breeds. The current study estimated heritabilities and genetic correlations for 13 meat quality traits recorded on lamb loins from Hu sheep. Heritability estimates ranged from 0.

It is still unclear whether adding immunosuppressive therapy to ursodeoxycholic acid (UDCA) benefits those patients who are not fulfilling the diagnostic criteria of PBC with autoimmune hepatitis (AIH) features.
Objectives: To assess the efficacy of adding immunosuppressive therapy to UDCA for patients with PBC and autoimmune phenomena but not fulfilling the diagnostic criteria of PBC with AIH features.
Liver cirrhosis remains a major health concern globally, but its epidemiology and etiology evolve with time. However, the changing pattern in etiology and cause of liver-related mortality for patients with cirrhosis are not fully elucidated. Herein, our aim was to characterize the temporal trend of the etiological spectrum and evaluate the impact of etiology on liver-related death among patients with compensated cirrhosis (CC) in Beijing, China.

Spermatogenesis-associated 6 (SPATA6) is an evolutionarily conserved testis-specific gene reported in many species. However, the effect of SPATA6 expression levels on testicular development and the effect of single nucleotide polymorphisms (SNPs) on testis and epididymis phenotype in sheep have not been studied.

However, the long-term clinical benefits of fibrosis regression have not been fully elucidated. This study investigated the association between biopsy-proven fibrosis regression by predominantly progressive, indeterminate, and predominantly regressive (P-I-R) score and liver-related events (LREs) in chronic hepatitis B patients.

Whether beta-blockers could additionally enhance the effects during treatment, particularly for small esophageal varices (EV), was unclear. This study aims to assess the efficacy of add-on carvedilol to delay EV progression during anti-hepatitis B virus (HBV) treatment in HBV-related cirrhosis.
View Article and Find Full Text PDFDespite the increasing prevalence of steatosis in patients with chronic hepatitis B (CHB), whether the changes in steatosis impact fibrosis regression during antiviral therapy remain unclear. We aimed to identify the association between histological changes of steatosis and fibrosis in patients undergone antiviral treatment. Patients with paired liver biopsies before and after 78 weeks of antiviral therapy were enrolled in this study.
View Article and Find Full Text PDFObjectives: Long-term treatment with nucleoside analog (NA) reduces the risks for decompensation and hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients with compensated cirrhosis (CC). However, whether antiviral therapy has differential efficacy on the risks for decompensation and HCC is insufficiently elucidated. Therefore, we investigated the disease state transition, focusing on decompensation event-specific HCC risk in NA-treated CHB patients with CC.
View Article and Find Full Text PDFBackground: The upper limits of normal (ULNs) of ALT are not consistent across the major international guidelines which may affect the eligibility for antiviral therapy for chronic hepatitis B (CHB).
Aim: To estimate the proportions of histological changes among treatment-naïve patients with CHB within differently defined ALT ULNs.
Methods: We searched PubMed and Embase up to May 15th, 2023, to identify studies of treatment-naïve CHB patients with liver biopsies.
Background: To investigate the joint impact of sarcopenia and frailty on mortality and the development of decompensation in cirrhosis.
Methods: Sarcopenia was assessed using the skeletal muscle mass index (SMI) by computed tomography, whereas frailty was measured using the Fried Frailty Phenotype (FFP). Cox proportional hazard regression and competing risks analysis were used to evaluate their association with adverse outcomes.
Transcatheter aortic valve replacement (TAVR) technology is quickly advancing in clinic, however, as it expands to low-risk populations and younger patients (age <65 years), device durability is becoming a major challenge. Tissue-engineered heart valves (TEHVs) are a potential alternative. In this study, a bionic tri-layer tissue-engineered heart valve was constructed using poly (L-lactate--ε-caprolactone) (PLCL), gelatin (GEL), hyaluronic acid (HA) and silk fibroin (SF), to simulate the fibrosa, spongiosa and ventricular layer of natural heart valves.
