Gastroesophageal variceal hemorrhage is the most important clinical event that results from portal hypertension. It is a lifethreatening condition that demands rapid and efficient treatment. The first step in bleeding control is hemodynamic stabilization and pharmacological treatment, which includes administration of vasoactive drugs and short-term antibiotic prophylaxis. After initial hemodynamic stabilization, endoscopic therapy should be performed. The first choice of endoscopic treatment for esophageal bleeding is endoscopic variceal ligation (EVL), or endoscopic injection sclerotherapy (EIS) if EVL cannot be performed...

Oxymatrine (OXY) has antioxidative and antiinflammatory activities. In the present work, we investigate the effects of OXY on gastric ulcer models and elucidate the underlying mechanisms of action. Ethanol, indometacin, and restraint water immersion stress-induced ulcerated models were used. The ulcer area was measured, and samples of gastric tissue were taken for pathological, histochemical, and biochemical analyses. OXY effectively reduced the area of gastric ulcers and improved the pathological changes of ulcerated tissue...

AIMS: Hereditary diffuse gastric cancer (HDGC) is an autosomal dominant syndrome characterized by multigenerational diffuse GC and is mainly caused by germline alterations in the CDH1 gene. Currently, endoscopy has limited diagnostic accuracy and total gastrectomy (TG) is the treatment of choice for asymptomatic CDH1 carriers. In this study, we aimed at a better understanding of HDGC syndrome, by exploring the histopathological findings of TG specimens from asymptomatic HDGC patients...

PURPOSE: Previous human epidermal growth factor receptor-2 (HER2)-derived resistance studies were based on ex vivo models, which could not mirror evolutionary expression of HER2 during therapy. To investigate dynamic expression of HER2 and its contribution to developing therapeutic resistance conferred by chromosome aneuploidy, both HER2 phenotype and chromosome 8 aneuploidy on CTCs were co-examined in advanced gastric cancer (AGC) patients. EXPERIMENTAL DESIGN: Total of 115 AGC patients, including 56 of histo-pathological HER2+ (hHER2+ ) subjects who received first-line HER2-targeted therapy plus chemotherapy, and 59 of hHER2- patients who received chemotherapy alone, were prospectively enrolled...

Cadherins seem to play and important role in prostate cancer (PCa) progression. E-cadherin loss of expression has been associated with poor prognosis; P-cadherin's role is still elusive. Although pT3 PCa is often considered "high-risk cancer," it does not exhibit an uniformly poor prognosis. Herein, we assessed the prognostic value and survival impact of E-cadherin and P-cadherin immunoexpression in pT3 PCa. Radical prostatectomy (RP) specimens from 102 pT3 PCa patients treated between 1991 and 2014 in a single institution were designated for E-cadherin and P-cadherin immunoexpression analysis...
