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.

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.

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.

Objective To investigate the moderator of children' s perceptions quality of parental involvement on parenting style and children' s sport expectancy-value beliefs.Methods 595 students of grade 2 to 6 from five elementary schools were chosen and analyzed.Data were analyzed by SPSS16.0 software packet using independent sample t test,One-Way ANOVA,correlation analysis and hierarchical regression statistical analysis of regulation.Results Children' s expectancy beliefs was predicted by authoritarian and behavior encouragement(β=0.076,t =2.35,P=0.019 ;β =0.111,t =3.748,P =0.000).Children' s value beliefs was predicted by affect -warmed and behavior encouragement (β =0.070,t =2.883,P =0.004 ;β =0.070,t =2.745,P =0.006).Children' s sport behavior was predicted by trust-encouragement(β=0.294,t=3.193,P=0.001).The prediction of expectancy beliefs was significant positive by the interaction between indulgence and time involvement (β=0.078,t =2.065,P =0.039).The prediction of expectancy beliefs was significant negative by the interaction between authoritarian and time involvement(β=-0.084,t =-2.454,P=0.014).The prediction of expectancy beliefs was borderline significant positive by the interaction between neglecting and equipment provision(β=0.073,t =1.94,P =0.053).Conclusion Different parenting styles are significant predicators of children sport involvement.Children' s perceptions quality of parental involvement play an important role on parenting style and children' s sport expectancy-value beliefs.

Acute leukemia (AL) is a malignant disease of clonal hematopoietic stem cell abnormalities.Chemotherapy is the main method for the treatment of AL,but the chemotherapy drug resistance has become a major obstacle to successful treatment.There is often a series of drug cooccurrence of drug resistance,and that is multidrug resistance.

Objectives:To observe the therapeutic effect of Cuochuang Misture on acne vulgaris and study the mechanism by external bacteria repressing experiment.Methods:34 cases of acne of syndrome of dampness and heat in lung and stomach were treated with Cuochuang Misture and 28 cases with Dangguikushen Pill as controls,and their curative effect were compared;Different concentration of Cuochuang Misture were used to inhibit Propionibacterium acnes(P.ance)and Malassezia furfur(M.furfur).Results:The clinical total effective rates were 94.12%in the treatment group,and 89.29%in the control group.The scores of skin lesions and syndromes reduced obviously between two groups in the end of the treatment(P

In critically ill patients,evoked potential(EP) testing is an important tool for measuring neurologic function,signal transmission,and secondary processing of sensory information in real time.EP potential measures conduction along the peripheral and central sensory pathways with longer-latency potentials representing more complex thalamocortical and intracortical processing.In critically ill patients with limited neurologic exams,EP provides a window into brain function and the potential for recovery of consciousness.Brainstem auditory EP and cortical event-related potentials are most commonly used in ICU.The primary indications for EP in critically ill patients are prognostication in anoxic-ischemic or traumatic coma,monitoring for neurologic improvement or decline,and confirmation of brain death.Historically,EP has been regarded as a negative prognostic test,that is,the absence of cortical potentials are associated with poor outcomes while the presence cortical potentials are prognostically indeterminate.In recent studies,the presence of middle-latency and long-latency potentials as well as the amplitude of cortical potentials is more specific for good outcomes.Event-related potentials,particularly mismatch negativity of complex auditory patterns,is emerging as an important positive prognostic test in patients under comatose.In infants,other than anoxic-ischemic or traumatic brain injury,brainstem auditory is also widely used in premature baby,bilirubin encephalopathy and detection of possible hearing loss.

Objective To investigate the 2-year retention rates and tolerability of levetiracetam (LEV), Lamotrigine(LTG), and Oxcarbazepine(OXC) in pediatric patients with epilepsy.Methods 310 pediatric patients with epilepsy were included in this study: LEV (n=145), LTG (n=101), and OXC (n=64). The clinical efficacy, first discontinuation time and discontinuation reasons were recorded and compared. The retention rates at 12, 24, 52 and 104 weeks were evaluated. Results At the two-year follow up:Clinical efficacy didn't significantly differ among the three groups (P = 0.190); The 2-year retention rates for LEV, LTG, and OXC, were 68.28%, 72.28%, and 48.44%, respectively (P = 0.002). LEV and LTG had equivalent retention rates, whereas OXC retention was significantly inferior to the LEV and LTG retention (P<0.05). The common reasons for drug discontinuation were adverse effects (47.66%) and lack of efficacy (42.10%), while the rate of adverse effects leading to drug withdrawal of OXC (66.77%) was higher than that of LEV (36.96%, P = 0.003) and LTG (42.86%, P = 0.023). Conclusion These results suggested that LEV, LTG and OXC had similar clinical efficacy. LEV and LTG had comparable retention profiles and long-term tolerability in the 2-year treatment, while OXC therapy seemed to be relatively less useful. If there are no specific contradictions, pediatric patients with epilepsy could be better receiving LEV and LTG antiepileptic treatment.
