Liver failure progresses rapidly,and patients with this disease are usually in a critical condition.The medical treatment of liver failure has unsatisfactory results,leading to a high mortality.How to accurately judge the prognosis of patients with liver failure according to their clinical manifestations and laboratory test results is a very good guide for clinical treatment strategies and donor liver allocation.The prognostic models for liver failure,such as CTP score,MELD and its derivative scoring system,KCH criteria,SOFA score,APACHE sco-ring system,SMSVH score,Clichy criteria,and ANN,are reviewed.These models are used to guide the development of clinical treatment strategies and screen out patients eligible for liver transplantation.In addition,the prognostic values of these models for liver failure and their differences are evaluated.

In National Comprehensive Cancer Network guideline, patients with the clinical stages of Ⅰ B-ⅢA esophageal neoplasms should be given radical PF regimen (cisplatin + 5-fluorouracil) concurrent chemoradiotherapy.The majorization PF and radiation dosage are studied by some scholars in China and abroad, and the local control rate and survival rate are improved, adverse reaction is within a controllable range.In recent years, some new drugs such as capecitabine, paclitaxel, docetaxel, pemetrexed and carboplatin also show their advantages in radical concurrent chemoradiotherapy.

There is overwhelming evidence for an involvement of reactive oxygen species(ROS) in the pathogenesis of atherosclerosis(AS) in diabetes mellitus(DM). For many years, knowledge on the contribution to diabetic complications and vascular disease induced by advanced glycation end-products(AGEs)has been rising. During the development of atherosclerosis, AGEs and ROS might have interaction. In this article, we provided four angles of view to discuss the role of ROS in the pathogenesis of atherosclerosis: the chemistry of ROS, the effect of vascular targets of ROS on activity of AGEs, the role of ROS in the pathogenesis of atherogenesis by AGEs, the same effect of ROS and AGEs-transcriptional regulation.
