Objective To investigate the distribution and antimicrobial resistance of the clinical isolates from Children's Hospital of Chuzhou during 2014.Methods A retrospective analysis was conducted with the bacterial strains isolated from various clinical specimens in 2014.Results A total of 382 clinical isolates were collected during 2014, of which gram positive organisms and gram negative organisms accounted for 37.4 % and 62.6 %, respectively. The top 5 most frequently isolated microorganisms were E. coli (18.8 %),K. pneumoniae (16.8 %), coagulase negative Staphylococcus (13.1 %),S. pneumoniae (9.4 %) and S. aureus (9.2 %). The prevalence of MRSA was 28.6 % in S. aureus and the prevalence of MRCNS was 76 % in CNS. All staphylococcal strains were susceptible to daptomycin, linezolid and vancomycin. All the E. faecalis and E. faecium isolates were sensitive to daptomycin, linezolid and vancomycin. All the S. pneumoniae strains were susceptible to penicillin. The prevalence of extended spectrum-lactamases (ESBLs) positive strains was 58.3 % in E. coli and 28.1 % in K. pneumoniae. The Enterobacteriaceae strains were highly sensitive to carbapenems. Only 3 (1.6 %) carbapenem-resistant strains were identified in the Enterobacteriaceae isolates. About 13.3 % and 6.7 % of theP. aeruginosa isolates were resistant to piperacillin and levofloxacin, respectively. All the P. aeruginosa strains were sensitive to the other antimicrobial agents. The percentage of carbapenem-resistantAcinetobacter strains was lower than 10 %. Only one carbapenem-resistant A. baumannii strain was identified.Conclusions Gram negative microorganisms account for most part of the clinical bacterial isolates in 2014. The antimicrobial resistance is still very serious in this hospital, especially the emergence of carbapenem-resistant Enterobacteriaceae, which is of great concern.

Objective To study the risk factors of prolonged postoperative recovery after the total cavopulmonary connection(TCPC) in the current era.Methods Data on all patients admitted to the cardiac intensive care unit (CICU) after a TCPC between January 2013 and March 2014 were retrospectively analyzed.We excluded all patients who died and required TCPC takedown.The study cohort was further divided into a prolonged recovery group that included patients with 75％ ile for duration of mechanical ventilation or pleural drainage,and a standard recovery group which included all other patients.A multivariable logistic regression model was used to compare demographic,anatomic,and physiological variables between the prolonged and standard recovery groups.Then,the cohort was separated into a high volume resuscitation group and a low volume resuscitation based on the 75％ ile for volume resuscitation(ml/kg) administered on the first three days after the TCPC.Results Totally 118 TCPC operations were performed.Of the study population (n =118),the median age was 3.8 years (3.1 to 4.8 years) and median weight was 14.8 kg(13.3 to 17.1 kg).The most common diagnosis was double outlet of right ventricle (n =47,39.8％).The extracardiac conduit fenestrated TCPC was the most common surgery(n =79,66.9％).Within the study population,43 (39.8％) patients met criteria for prolonged recovery.Univariate risk factors for prolonged recovery included higher preoperative mPAP(P =0.022),atrioventricular valve regurgitation (P =0.000),longer total bypass time (P =0.044),higher postoperative central venous pressure (P =0.000),AST (P =0.001),ALT (P =0.010),NT-proBNP (P =0.000),SaO2 (P =0.012),I n-otropic score (P =0.001),higher incidence of arrhythmia (P =0.000),low cardiac output syndrome (P =0.000),need for peritoneal dialysis (P =0.000),and requirement for greater volume resuscitation during the 72 postoperative hours(75％ for the entire group,P =0.000).In a multivariable Logistic model,need for greater volume resuscitation (OR 10.860,95 ％ CI 2.681,43.987) and the higher postoperative central venous pressure (OR 1.446,95 ％ C I 1.113,1.879) were the only two independent risk factors for prolonged outcome after the TCPC.Conclusion The need for high volume expansion and higher central venous pressure were the risk factors of mediate prolonged recovery.

Protein-coding transcriptome,pseudogenes,long non-coding RNAs and circular RNAs can act as competing endogenous RNA (ceRNA).ceRNA can crosstalk with each other through microRNA recognition elements (MRE),thus regulating the post-transcriptional gene expression.More and more evidences showed that ceRNA could form an extensive network of post-transcription regulation,keep the cell homeostasis and involve in the disease development and progression like tumorigenesis and cancer progression.Depending on up-regulation or down-regulation of different kinds of microRNA in different cells,ceRNA acts as either an oncogene or a tumor suppressor.ceRNA may have a great potential in cancer diagnosis and treatment.
