Diabetes-related macular exudation is a common fundus change associated with diabetes mellitus,charactered by hard exudates of macular area.It is one of main causes of lowing vision in diabetic patients.The incidence of diabetes-related macular exudation is increasing recent years,and therefore the diabetic maculopathy is also a matter of urgent concern.Domestic and international studies suggested that many systemic factors,such as blood glucose level,blood pressure,hypertension,higher blood lipid,inflammatory factors and genetic predisposition,exert impacts in the pathogenesis and development of diabetic retinopathy.However,whether the hard exudates of macular area also is associated with systemic factors mentioned above is unclear up to now.Since the hard exudates of diabetic maculopathy may leads to permanent loss of visual function,it is very important for us to find the effective prevent and managing approaches.This paper aimed to review the progress in this field and summarize the relevant risk factors that must be strictly controlled.

Sepsis is a complex systemic inflammatory response syndrome caused by infection.Sepsis can deteriorate to severe sepsis,septic shock,and multiple organ dysfunction syndrome.Due to the use of antimicrobial agents,fluid resuscitation and the developments of all kinds of support life,the treatment of sepsis has greatly improved over the past years.However,the mortality rates of sepsis still remain high.Rapid,accurate and early diagnosis of sepsis is a key factor to lower the high mortality rate of sepsis.Recently,it has been found that some biomarkers are closely associated with early diagnosis of sepsis and are helpful for the treatment.These biomarkers for early diagnosis include presepsin(sCD14-subtype),neutrophil CD64,soluble triggering receptor expressed on myeloid cells-1 (sTREM-1),soluble CD163,microRNAs,copeptin,and so on.Examining these biomarkers alone or in combination will bring new opportunities for the early diagnosis of sepsis,and hopefully provide new ideas for the treatment of sepsis.This article reviews the progress on the current emerging biomarkers for early diagnosis of sepsis.

Staphylococcus aureus continues to be a major pathogen in both community and healthcare associated infections.The pathogenicity of staphylococcus aureus is a complex process involving a variety of extracellular and cell wall components that are coordinately expressed during different stages of infection.Accessory gene regulator (agr)-mediated quorum sensing plays a major role in staphylococcal pathogenesis.However,agr dysfunction strains exist extensively in staphylococcus aureus clinical isolates.This review will mainly focus on the influence of agr dysfunction on staphylococcus aureus biofilm formation,clinical course and outcome of infectious diseases,and antibiotic resistance.

Hepatic veno-occlusive disease (HVOD) is a serious complication of hematopoietic stem cell transplantation.The mortality rate of severe HVOD (sHVOD) approaches 100 ％.Defibrotide (DF) is a polydisperse mixture of single-stranded oligonucleotides with antithrombotic and fibrinolytic properties.Numerous clinical trials have demonstrated its effectiveness and safety in the prevention and treatment of HVOD.This review focuses on the possible mechanisms of action of DF and its use in the prevention and treatment of HVOD.
