Objective To investigate the protective effects of propofol on liver against hypoxia/reoxgenation (H/R) injury in rats. Methods Twenty-four Wistar rats of both sexet weighing 200-250g were randomized into control group (group A), hypoxia/reoxygenation group (group B) and H/R + propofol group (group C). The 8-iso-prostaglandin F 2? (8-iso-PGF 2? ) level in the hepatic tissue was determined by enzyme-linked immunosorbent assay (ELISA). The content of NO and the activity of NOS were assessed by biochemical methods. Results In group B, the 8-iso-PGF 2? level in hepatic tissue was significantly higher than that in group A (P

Clinical, radiological and pathological presentations in two children with epidermal nevus syndrome were analyzed and relevant literature was reviewed.Two patients both had typical epidermal nevus and abnormal cerebral radiography, which was associated with mental retardation, epilepsy, language and movement retardation.One case was complicated with an ocular tumor.Pathological investigations of the epidermal nevus revealed papilliform proliferation in squamous epidermis.The disorder may have a systemic involvement besides cutaneous lesions, with a predilection for the central nervous system.Early diagnosis and therapy may help to improve patients life quality.
