Five hundred and ninety-one papers retrieved from CAJD on performance assessment of electronic re-sources in domestic libraries from 2004 to 2013 were retrospectively analyzed by biliometrics, which showed that these papers focused on the description of projects,methods of assessment,and establishment of assessment indexes. The following problems were pointed out, such as weakness in research strength, tendency to stress theories, inopera-tive methods used in studies, and single-valued achievements, with suggestions put forward for their solution such as intensifying cooperation and focusing on practice in future studies.

Objective To establish an evaluation index system for access to ophthalmic surgery so as to standardize the access. Method Collect 14 ophthalmologists' recommendations on access criteria for ophthalmic surgery in two rounds of questionnaire survey by Delphi method. Results The return rate of rounds of consultation questionnaire was 93.33%, and the average expert authority coefficient was 0.78.Nine ophthalmic surgery access indicators were established. The coordination of expert coefficient was 0.521 after two consultation. It had significant difference ( P＜0.01 ). Conclusion The ophthalmic surgery access indicator system is highly credible and allows quantitative assessment of ophthalmic surgery from various aspects. It is more demanding for ophthalmologist, and gets more involvement of patients in the evaluation of ophthalmic surgery access. It could contribute to scientific and rational decision-making on access for ophthalmic surgery.

Objective To investigate the diagnostic value of D-dimer age-adjusted threshold in elderly patients with Pulmonary thromboembolism(PTE).Methods Collected patients older than 50 years of suspected PTE,who visited Yan′an People′s Hospital and the Hospital Affiliated to Yan′an University from June 2015 to September 2016,using the revised Geneva criteria for clinical probability assessment firstly.The low-risk group was excluded from the study;the patients with moderate-to-high risk were performed D-dimer detection and CTPA.All patients determined both by D-dimer age-adjusted thresholds and traditional thresholds,comparing the diagnostic efficacy of the two methods subsequently.Results 163 patients were diagnosed with PTE by CTPA among the 549 subjects,the positive rate was 29.69％.The diagnostic sensitivity of plasma D-dimer was 83.44％,78.53％,the specificity was 17.88％,31.61％ respectively,the missed diagnosis rate was 16.56％,21.47％,respectively.The misdiagnosis rates were 82.12％ and 68.39％,respectively,and the Younden index was 0.013 2 and 0.101 4 respectively.All subjects were divided into four groups according to age:50-60 years,60-70 years,70-80 years,and equal or greater than 80 years age group.Compared with the traditional threshold,the misdiagnosis rates of the four groups of age-adjusted thresholds decreased by 4.00％,15.70％,21.36％ and 17.39％,respectively and the specificity was increased by 1.23,1.65,2.56 and 3.00 times,respectively.Conclusion The diagnostic accuracy of the age-corrected threshold is higher than the traditional threshold;combined with clinical practice,the optimal threshold is determined by the ROC curve,the clinician can serve as a reference.

A method to assess library-holding journals according to their weighted citations was proposed in light of the actual needs of users for core journals, the use of library-holding journals and references by authors in different orders of precedence.The Western journal of rheumatology, highly cited by authors of Second Military Medical U-niversity, were assessed using this method, showing that this method is better than the citation analysis-based tra-ditional method in assessment of journals.

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 investigate the distribution and antibiotic resistance of gram-negative bacilli for better antimicrobial therapy in our hospital.Methods A retrospective analysis was conducted for the 1 060 strains of gram-negative bacilli isolated from clinical specimens during 2013.Results Of the 1 060 gram-negative bacterial strains isolated during 2013,E.coli,K . pneumoniae,P .aeruginosa and A.baumannii were the leading pathogens,accounting for 29.3%,22.8%,11.5% and 9.9%,respectively.The prevalence of extended spectrum-lactamases (ESBLs)positive strains was 63.7%,32.2% and 28.0% in E.coli,K .pneumoniae and P .mirabilis,respectively.The Enterobacteriaceae strains were highly sensitive to carbapenems.The percentage of the P .aeruginosa isolates resistant to meropenem,imipenem or amikacin was lower than 30%.The percentage of the Acinetobacter spp.(A.baumannii accounted for 70.9%)strains resistant to meropenem and imipenem were 25.0% and 26.2%.Conclusions Most of the gram-negative bacilli are resistant to multiple antimicrobial agents. We should strengthen the monitoring of the antibiotic resistance of gram-negative bacilli and optimize antimicrobial therapy.
