Emperipolesis mediated by CD8 T cells correlates with biliary epithelia cell injury in primary biliary cholangitis.

Primary biliary cholangitis (PBC) is an autoimmune disease characterized by chronic destruction of the bile ducts. A major unanswered question regarding the pathogenesis of PBC is the precise mechanisms of small bile duct injury. Emperipolesis is one of cell-in-cell structures that is a potential histological hallmark associated with chronic hepatitis B.

Serum soluble CD40 is associated with liver injury in patients with chronic hepatitis B.

Soluble cluster of differentiation 40 (sCD40) is proteolytically cleaved from membrane-bound CD40 and binds to CD154, thereby inhibiting CD40-CD154-mediated immune responses. The aim of the present study was to clarify the role of sCD40 in chronic hepatitis B (CHB). The sCD40 levels in sera from 132 patients with CHB and 33 healthy individuals were retrospectively measured.

[Clinical value of acoustic radiation force impulse imaging for quantitative evaluation of degree of liver fibrosis in chronic hepatitis C patients].

Objective: To investigate the diagnostic value of acoustic radiation force impulse (ARFI) imaging technology for the assessment of liver fibrosis in chronic hepatitis C (CHC) patients.

Methods: One-hundred-and-eight CHC patients were examined by real-time ultrasound elastography using the Acuson S2000 ARFI instrument (Siemens Healthcare) and underwent liver biopsy for pathohistological analysis. The correlation between liver fibrosis grades determined by the two approaches was analyzed.

[Expression of CAS in hepatocellular carcinoma tissues and its relationship with HBV infection].

Objective: To explore whether the cellular apoptosis susceptibility (CAS) protein could serve as a pathologic marker for HCC diagnosis and the roles of CAS expression in HBV infection associated HCC.

Methods: The expression of CAS protein in HCC and its paracarcinoma tissues, non-tumor liver cirrhosis and hepatitis tissues were detected by immunohistochemistry. Meanwhile, HBsAg, HBcAg and HBV DNA in HCC tissues with HBV infection were examined by immunohistochemistry and in situ hybridization respectively.

Rhein protects against acetaminophen-induced hepatic and renal toxicity.

This study investigated the possible protective effects and mechanism of rhein on Acetaminophen (APAP)-induced hepatotoxicity and nephrotoxicity in rats. Treatment of rats with APAP resulted in severe liver and kidney injuries, as demonstrated by drastic elevation of serum glutamate-pyruvate transaminase (GPT), glutamate-oxaloacetic transaminase (GOT), total bilirubin (TBIL), creatinine (CREA), urea nitrogen (UREA) levels and typical histopathological changes including necrosis, phlogocyte infiltration and fatty degeneration in liver, tubules epithelium swelling and severe vacuolar degeneration in kidney. APAP caused oxidative stress, as evidenced by increased reactive oxygen species (ROS) production, nitric oxide (NO) and malondiadehyde (MDA) levels, together with depleted glutathione (GSH) concentration in the liver and kidney of rats.

Investigations of free anthraquinones from rhubarb against alpha-naphthylisothiocyanate-induced cholestatic liver injury in rats.

The protective effects of anthraquinones from Rhubarb, a Chinese herbal medicine, consisting of the root and rhizome of Rheum palmatum L., R. tanguticum Maxim.

Chitosan ameliorates the severity of steatohepatitis induced by high fat diet in rats.

Objective: Currently, no agent has been conclusively demonstrated to prevent the progression of non-alcoholic steatohepatitis (NASH). Chitosan, a natural product derived from chitin, was thought to possess hypocholesterolemic properties. The aim of this study was to evaluate the potential effects of chitosan on nutritional steatohepatitis in rats.

[Clinical and pathological analysis of 100 cases of drug-induced liver injury].

Objective: To study the clinical and pathological features of drug-induced liver injury (DILI).

Methods: Liver specimens were obtained through needle biopsies from 100 patients with DILI. The histological preparations of the specimens were stained with haematoxylin eosin, several histochemistry methods, and immunohistochemistry stains.

[Immunohistochemical evidence for HIV-1 infection in the liver of HIV-infected patients].

Objective: To detect p24 antigen of human immunodeficiency virus (HIV)-1 in the liver biopsy specimens of patients with HIV infection.

Methods: Liver biopsy samples from 14 patients with HIV/AIDS (11 man, 3 women; age range 27-52 years; infection time range 8-13 years) were examined by immunohistochemistry prospectively.

Results: Intracellular expression of HIV-1 p24 antigen was detected in Kupffer cells, endothelial cells and hepatocytes.

[Dynamic expression of matrix metalloproteinase-2, membrane type-matrix metalloproteinase-2 in experimental hepatic fibrosis and its reversal in rat].

Objective: To investigate the expression dynamics and significance of matrix metalloproteinase-2 (MMP-2) membrane type-matrix metalloproteinase-2 (MT-MMP-2) in hepatic fibrosis and its reversal counterpart.

Methods: An experimental CCl4 induced hepatic fibrosis rat model was established by intraperitoneal administration of carbon tetrachloride for 2, 4, 6, 8, 10 weeks, and normal rats were used as a control group. The immunohistochemical methods and in situ hybridization were used to detect MMP-2,MT-MMP-2 mRNA and related antigens in the liver.

[Growth inhibition of human hepatocellular carcinoma xenograft in nude mice by combined treatment with human cytokine-induced killer cells and chemotherapy].

Objective: To compare the inhibitory effects of cytokine-induced killer (CIK) cells alone, chemotherapeutic drug alone, and CIK cells combined with chemotherapeutic drug on the growth of hepatocellular carcinoma (HCC) cells transplanted in nude mice.

Methods: Peripheral blood mononuclear cells (PBMC) collected from five healthy donors by blood cell separator were incubated in vitro to induce CIK cells in the presence of interferon-gamma (IFN-gamma), IL-2 and anti-CD3 monoclonal antibody (mAb). The phenotype of CIK cells was characterized by flow cytometric analysis.

[Cut-off period of subclassification and pathological features of severe hepatitis based on clinical and pathological analyses].

Background: To explore the cut-off period of subclassification and pathological features of severe hepatitis (SH).

Methods: Based on combined clinical and pathological analyses, the complete clinical and biopsy or autopsy liver tissues data from 196 cases of patients with severe hepatitis were investigated. Meanwhile, proliferative hepatocytes, cholangioepithelia and collagens were identified by a panel of monoclonal antibodies such as those against albumin, cytokeratin 18,19 and collagen I, III with immunohistochemical method.

Background: To explore the pathological features and pathogenesis of severe acute respiratory syndrome (SARS) to provide evidence for the clinical treatment and prevention of SARS.
