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.

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.

Objective To investigate the expressions of excision repair cross complementation group 1 ( ERCC1) and Ki67 in patients with breast cancer, and the relationships between their expressions and sensitivity of platinum-based chemotherapy. Methods Totally, 129 cases were pathologically diagnosed as breast cancer.Paclitaxel and carboplatin were used simultaneously. Chemotherapy regimen was as follows:Gemcitabine 1 000 mg??( m2 )-1 , IV drop on day 1 and 8;cisplatin 25 mg??( m2 )-1 , IV drop on day 1-3, for six cycles ( 21 days a cycle ) . ERCC1 and Ki67 expression in tumor tissue was observed by immunohistochemical analysis.Platinum-based chemotherapy sensitivity and survival of patients with different levels of ERCC1 and Ki67 expression were analyzed. Results In 129 patients, 18 cases were ERCC1 and Ki67 double-negative ( ERCC1-Ki67-) , and the clinical effective rate and 3-year cumulative survival rate were 88.89%and 83.33%, respectively.Twenty-four cases were ERCC1 positive but Ki67 negative ( ERCC1+Ki67-) , and the clinical effective rate and 3-year cumulative survival rate were 50. 00% and 62.50%, respectively.Thirty-three cases were ERCC1 negative but Ki67 positive (ERCC1-Ki67+), and the clinical effective rate and 3-year cumulative survival rate were 54. 55% and 60. 60%, respectively. Fifty-four patients were ERCC1 and Ki67 double-positive ( ERCC1+Ki67+) , and the clinical effective rate and 3-year cumulative survival rate were 22.78% and 31. 48%, respectively.Compared with ERCC1-Ki67- group, the clinical treatment efficiencies of cisplatin-based chemotherapy in ERCC1+Ki67- group, ERCC1-Ki67+ group, and ERCC1+Ki67+ group were significantly decreased ( P<0. 05 ) . The clinical treatment efficiency in patients of ERCC1+Ki67+ group with cisplatin-based chemotherapy was significantly decreased as compared with ERCC1+Ki67- group and ERCC1-Ki67+ group (P<0.05).Compared with ERCC1- Ki67- group, three-year cumulative survival rate in patients of ERCC1+ Ki67- group and ERCC1- Ki67+ group, ERCC1+Ki67+ group was significantly decreased ( P<0. 05 ) . Compared with ERCC1+Ki67-group and ERCC1-Ki67+group, three-year cumulative survival rate in patients of the ERCC1+Ki67+group was significantly decreased ( P<0.05) . Conclusion The expression levels of ERCC1 and Ki67 in breast cancer were high. Their expression levels are closely related with clinical efficiency of platinum-based chemotherapy.

Objective:To analyze and evaluate the effect after the PIVAS workflow optimization in our hospital. Methods: One-for-one grouping preparation was carried out by pharmacists and nurses. The checking of medicines, solvents and empty ampoules be-fore and after the preparation was performed by pharmacists, and the preparation of infusions was operated by nurses according to the operation specification. The preparation workload, error number in each link and damage of ampoules and finished goods before the op-timization and in 5 months after the optimization were compared. Results:The working efficiency was obviously improved with less time of about 0. 5 h for the same workload, the error rate was decreased by 40%, and the ampoule damage was reduced by 60% before and during the preparation. Conclusion:The PIVAS workflow optimization improves the working efficiency and management level.

Objective To investigate the information ability of medical personnel from a large general hospital that integrates medical care,teaching and research under the network environment for providing evidence to improve targeted information service in library.Method A self-designed and self-administered questionnaire was distributed through the questionnaire system on hospital office network.Information ability involved in the questionnaire mainly included the ability to precisely retrieve literature in Chinese and foreign language,commonly used retrieval strategies,and screening,evaluation and English full-text access methods.A total of 1 094 medical personnel voluntarily participated and completed the questionnaire,and complete responses were obtained from 1 065 individuals (effective response rate 97.35％).x2 and trend x2 tests were used for data analysis.Results The overall accuracy of precise retrieval information was only 6.1％,and the accuracies of precise retrieval literature in Chinese and foreign language databases were 14.6％ and 14.6％,respectively.Duty,education and working years of the medical personnel had significantly effects on the ability to precisely retrieve literature and the strategies and methods of information retrieval,screening,evaluation and full-text access.Conclusion Medical personnel had certain information ability,but library should carry out relevant training program to improve the medical personnel's information quality and ability further.

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.
