Background And Aims: Although coexisting alcohol-induced liver disease and hepatitis B or C virus-induced liver cirrhosis (ALD + HBV or ALD + HCV) has been the center of recent hepatology researches, numerous controversies still persist. This study aimed to showcase the influence of alcohol on the laboratory values and on the clinical outcomes of patients with hepatitis B and C virus-induced liver cirrhosis.

Methods: Patients diagnosed with liver cirrhosis (n = 22,287) from January 2010 to December 2019 were enrolled, and divided into five groups according to the etiology: alcohol-induced liver disease (ALD, 1652 cases), hepatitis B virus (HBV, 18,079 cases), hepatitis C virus (HCV, 682 cases), ALD + HBV (1594 cases) and ALD + HCV (280 cases).

Background/ Aims: Early diagnosis of alcoholic liver cirrhosis (ALD) and coexisting ALD and hepatitis B virus-induced cirrhosis (ALD+HBV) is primordial for an optimal management of these conditions. However, the lack of specific noninvasive biomarkers coupled with the inaccuracy of self-reported alcohol consumption make the early diagnosis of these pathologies difficult. This study aimed to identify biomarkers to diagnose ALD and differentiate ALD+HBV from HBV.

Background: The incidence of gastric Burkitt lymphoma (BL), presenting as paraplegia and acute pancreatitis, is extremely low. BL is a great masquerader that presents in varied forms and in atypical locations, and it is prone to misdiagnosis and missed diagnosis. The prognosis of BL remains poor because of the difficulty in early diagnosis and the limited advances in chemotherapy.

Background: Butyrate acts as a regulator in multiple inflammatory organ injuries. However, the role of butyrate in acute liver injury has not yet been fully explored. In the present study, we aimed to investigate the association between butyrate and lipopolysaccharide (LPS)-induced acute liver injury and the signaling pathways involved.

Background: Endoscopic variceal sequential ligation (EVSL) is currently endorsed in our hospital, as the preferred endoscopic treatment for prevention of variceal rebleeding and achieving adequate hemostasis. There is currently a lack of consensus surrounding EVSL-induced changes in esophageal motor function and abnormal reflux.

Aims: To explore alterations in esophageal motor function and risk of abnormal gastroesophageal reflux in liver cirrhosis patients with esophageal varices, after EVSL.

BACKGROUND Adrenal insufficiency is mainly due to insufficient adrenal corticosteroid hormones secretion by the adrenal cortex, which leads to clinical manifestations such as weakness, weight loss, hyperpigmentation, hypotension, and vomiting. However, the clinical manifestations of adrenocortical insufficiency may be atypical: anorexia, ascites, impaired liver function, and alacrima have been reported. Jaundice and anorexia presenting together in the same patient as the main symptoms are rare.

Aim: To focus on procedure-related complications, evaluate their incidence, analyze the reasons and discuss the solutions.

Methods: Overall, 628 endoscopic gastric variceal obturation (EGVO) procedures (case-times) with NBC were performed in 519 patients in the Department of Endoscopy of the Third Affiliated Hospital of Sun Yat-Sen University from January 2011 to December 2016. The clinical data of patients and procedure-related complications of EGVO were retrospectively analyzed.

Aim: To analyze the clinical characteristics of eosinophilic gastroenteritis (EGE) and to investigate the situations of missed diagnosis of EGE.

Methods: First, the clinical characteristics of 20 EGE patients who were treated at our hospital were retrospectively summarized. Second, 159 patients who underwent gastroscopy and 211 patients who underwent colonoscopy were enrolled.

Although gastroduodenal ulcers are common in solid organ transplant patients, there are few reports on multiple giant ulcers in the distal ileum and ileocecal valve caused by immunosuppressants Herein, we report on a liver transplant recipient and a renal transplant recipient with multiple large ulcers in the distal ileum and ileocecal valve who rapidly achieved ulcer healing upon withdrawal of sirolimus or tacrolimus and administration of thalidomide. In case 1, a 56-year-old man with primary hepatocellular carcinoma had received a liver transplantation. Tacrolimus combined with sirolimus and prednisolone was used as the anti-rejection regimen.

Objective: To investigate the effects of shikonin on the proliferation, expression of CXCR4 and the migratory responses to CXCL12 in colorectal carcinoma cell line SW480.

Methods: The proliferation of SW480 cells was assessed by MTT assay. Cell surface expression of CXCR4 was determined by flow cytometry.

In the present study we investigated the in vitro apoptosis inducing effects of peroxisome proliferator-activated receptor-gamma (PPAR-gamma) ligand ciglitazone (CGZ) on acute promyelocytic leukemia (APL) NB4 cells and its mechanisms of action. The results revealed that CGZ (10-50 micromol/l) inhibited the growth of leukemia NB4 cells and caused apoptosis in a time- and dose-dependent manner. Apoptosis was observed clearly by flow cytometry (FCM) and DNA fragmentation analysis.

Article Synopsis
  • The study examines TLR4 expression in liver cells from Chronic Hepatitis B (CHB) patients and liver cancer cell lines (HepG2 and HepG2.2.15).
  • TLR4 was found to be primarily located in the cytoplasm of hepatocytes, with significantly higher expression in CHB patients compared to healthy controls, particularly in those with severe disease.
  • The research suggests that increased TLR4 expression may play a crucial role in the development and progression of Chronic Hepatitis B.

Background & Objective: A proliferation-inducing ligand (APRIL), a new member of the tumor necrosis factor (TNF) family, can stimulate tumor cell growth and proliferation both in vitro and in vivo. This research was to detect the expression of APRIL in colorectal carcinoma tissues, and to compare the effects of 5-fluorouracil (5-FU) and cisplatin (DDP) on the expression of APRIL in colorectal carcinoma SW480 cells.

Methods: The protein and mRNA levels of APRIL in 56 specimens of human colorectal carcinoma and para-tumor tissues and in SW480 cells were determined by immunohistochemistry and real-time fluorescence quantitative reverse transcription-polymerase chain reaction (FQ-RT-PCR).
