Liver biopsy is a well-known method for the diagnosis and evaluation of chronic diffuse liver diseases, especially among patients with "hepatopathy of unknown origin". ⋯ Liver biopsy - despite the increasing access to new, non-invasive methods - remains a useful method in the differential diagnosis of liver diseases.

Ischemia-reperfusion injury (IRI) is a serious complication of hepatectomy and liver transplantation. The aim of this study was to evaluate the protective effects of salvianolic acid-A (Sal-A) against IRI-induced hepatocellular injury. ⋯ Sal-A had a synergistically protective effect on the liver tissue against IRI that might be due to decreased oxidative stress, inflammation, hepatocellular apoptosis and include, at least in part, the regulation of TLR4.

Metabolic alterations have been recently associated with onset and progression of idiopathic pulmonary arterial hypertension (IPAH). We aimed to determine the prevalence and prognostic role of cardiovascular risk factors in patients with IPAH. ⋯ Patients with IPAH are characterized by an altered profile of lipid and glucose metabolism. Lowered levels of LDL-C and HDL-C and increased TG/HDL-C ratio correlate with disease severity and together with elevated plasma glucose level predict poor survival in IPAH.

The exfoliation of exfoliative cells from gastric serosa into the peritoneum is the main cause of peritoneal metastasis, which is the most common form of postoperative recurrence in gastric cancer. This study investigates the effects of vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF) on the biological properties of gastric cancer cells. ⋯ Lower survival was related to positive exfoliative cytology, lymphatic node metastasis, serosa-infiltrated and poorly differentiated gastric cancer. The expression of VEGF and EGF was correlated with the properties of gastric cancer cells. Specific inhibition of VEGF and EGF may impair the biological properties of gastric cancer cells in vitro.

The aim of the study was to evaluate the effects of blood pressure (BP) goals on cardiovascular outcomes in hypertensive patients. ⋯ In hypertension patients, when compared to uncontrolled hypertension patients, low therapeutic BP goal is associated with better cardiovascular outcomes than high therapeutic BP goal.
