Background And Aim: The aim of the present study sought to determine the protective function of Shenqi Fuzheng Injection (SFI) in cholestatic liver injury.
Methods: Cholestatic liver injury was induced in a 7-day bile duct-ligated (BDL) rat model. Rats were divided into three groups that were comprised of: (1) Sham; (2) BDL model; and (3) SFI treatment. The sham and BDL groups were treated with an appropriate volume of 0.9% sodium chloride as the vehicle, and the SFI group was administered SFI at a dose of 20 ml/kg/day, via tail vein injection.
Results: SFI significantly (all at <0.01) decreased the levels of serum aspartate aminotransferase and alanine aminotransferase as compared with the BDL group, which was associated with reduced severity of inflammatory cell infiltration and hepatic damage. Moreover, SFI significantly decreased the levels of hepatic interleukin-6 (<0.01), tumor necrosis factor-α (=0.041), and malondialdehyde (=0.026), and significantly increased the levels of total superoxide dismutase (<0.01), and the GSH/GSSG ratio (=0.041) in the liver. Western blot analysis showed that SFI increased PPAR-γ expression; however, SFI treatment decreased cyclooxygenase-2 (COX-2) expression and the phosphorylation of NF-κBp65.
Conclusions: These data demonstrated that SFI attenuated both inflammation and oxidative stress, and disrupted cholestatic liver injury. The involved mechanism was dependent, at least in part, on regulating PPAR-γ, COX-2, and NF-κBp65 expression.

Gallstones are among the most frequent hepatobiliary conditions. Although in most cases, they remain asymptomatic, they can cause complications and, in such cases, invasive treatments like endoscopic retrograde cholangiography (ERC) or cholecystectomy are required. Here, we present the results of genetic testing of a single family with a high incidence of symptomatic gallstones and cholestatic liver phenotypes.

Although loneliness and social isolation are proposed as important risk factors for metabolic diseases, their associations with the risk of non-alcoholic fatty liver disease (NAFLD) have not been elucidated. The aims of this study were to determine whether loneliness and social isolation are independently associated with the risk of NAFLD and to explore potential mediators for the observed associations. In this large prospective cohort analysis with 405,073 participants of the UK Biobank, the status of loneliness and social isolation was assessed through self-administrated questionnaires at study recruitment.

Primary Biliary Cholangitis (PBC) is a chronic cholestatic liver disease characterized by the progressive destruction of intrahepatic bile ducts, leading to fibrosis, and potentially cirrhosis. PBC has been considered a prototypical autoimmune condition, given the presence of specific autoantibodies and the immune response against well-defined mitochondrial autoantigens. Further evidence supports the interaction of immunogenetic and environmental factors in the aetiology of PBC.

Objectives: Indications of mitochondrial dysfunction are commonly seen in liver diseases, but data are scarce in primary sclerosing cholangitis (PSC). Analyzing circulating and liver-resident molecules indirectly reflecting mitochondrial dysfunction, we aimed to comprehensively characterize this deficit in PSC, and whether this was PSC specific or associated with cholestasis.
Materials And Methods: We retrospectively included plasma from 191 non-transplant patients with large-duct PSC and 100 healthy controls and explanted liver tissue extracts from 24 PSC patients and 18 non-cholestatic liver disease controls.

Aim: To compare the respective clinical and pathologic features of antimitochondrial antibodies-negative (AMA-negative) primary biliary cirrhosis (PBC) and cholestatic type drug-induced liver injury (DILI) for clinical differential diagnosis.
Patients And Methods: Clinical data from 23 patients with AMA-negative PBC and 39 patients with cholestatic type DILI, treated at our hospital between January 2013 and January 2024, were collected and retrospectively analyzed.
Results: The cholestatic type DILI group exhibited a higher incidence of malaise and abdominal pain compared with the AMA-negative PBC group.
