The problems of some hospital in medical equipment maintenance management were introduced from the aspects of maintenance time, maintenance record, maintenance service and self maintenance. Some measures were proposed including simplifying maintenance process through PDCA, informatizing maintenance record, cooperating with third-party maintainer and establishing self maintenance team, so that precision and informatized medical equipment management can be realized to maximize the benefit of medical equipment management.

Objective To investigate the genetic characteristic of whole-genome of influenza A/H3N2 viruses in severe acute respiratory infection cases in Beijing area.Methods From 2014 to 2016,the viral RNA was extracted from 32 strains isolated from SARI cases,then sequenced by Ion Torrent PGM Sequencer.The phylogeny and molecular features of whole-genome were analyzed by Mega and Consurf software.Results The HA gene of tested strains isolated in 2014-2015 influenza season belonged to lineage 3C.3a and 3C.2a,while those isolated in 2015-2016 influenza season belonged to cluster 3C.2a.Moreover,compared with the vaccine strains,7 variant amino acids of protein of HA1 were identified,and two of them were located in antigenic sites.All isolates were sensitive to neuraminidase inhibitors while showed resistance to blockers for M2 ion channel.Conclusion The phylogenetic features of isolates studied in this study are similar with that of current circulating strains.However,the difference between isolates and vaccines should not be overlooked.

ObjectiveTo survey 0—6 years old disabled children in Guiyang.Methods4 999 children aged 0—6 years old chosen randomly from 9 145 children of 12 blocks were investigated with the disability sampling survey criteria of 1987.ResultsThe rate of disabled children in Guiyang was 1.58%, and was not significantly different compared with that of whole country (1.36%) and other three areas including Siping City (P>0.05),but significantly higher than that of other six districts including Heping district of Tianjin municipality (P<0.05). All kinds of disability found by this survey were separately intellectual disability (0.92%),comprehensive disability (0.28%),limb disability (0.24%),vision disability (0.10%),psychiatric disability (0.03%),and hearing disability (0.02%). Rates of intellectual and vision disabilities were significantly higher than that of whole country ( P>0.05).ConclusionSome diseases are directly relative to occurrence of disability. The poor income of the children family,lower education of his parents and not gotten preschool education were risk factors of disability. The institution based rehabilitation and community based rehabilitation are main rehabilitation forms to disabled children.

Objective To explore the relationship between superantigen and M protein gene (emm)-types genes of Group A Streptococcus pyogenes (GAS) isolated from patients with scarlet fever in Beijing from May 2012 to July 2013 .Methods GAS was isolated from specimens of patients with scarlet fever . Superantigen genes (speA ,speB ,speC ,speF ,speG ,speH ,speI ,speJ ,speL ,speK ,speM ,ssa ,and smeZ) ,and emm gene were amplified by polymerase chain reaction .Rate and proportion were compared by chi-square test .Results Of the 423 GAS strains isolated from patients with scarlet fever from 2012 to 2013 ,most of the isolates possessed speB (97 .6% ) ,speC (99 .8% ) ,speF (98 .3% ) ,speG (99 .8% ) , smeZ (94 .1% ) and ssa (88 .4% ) ,and some of them possessed speH (54 .6% ) ,speI (53 .4% ) ,speA (45 .2% ) and speJ (43 .5% ) ,but very few isolates possessed speK (2 .4% ) ,speL (1 .4% ) and speM (1 .7% ) .Type emm12 (59 .5% ) and type emm1 (37 .4% ) were the main types of GAS .Most of the emm12-type isolates possessed speH (84 .8% ) and speI (84 .0% ) compared with only 4 .0% of speH and 3 .4% of speI in type emm1 .Most of type emm1 possessed speA (95 .3% ) and speJ gene (94 .6% ) compared with only 17 .3% of speA and 14 .8% of speJ in type emm12 .The superantigen genes profiles were significant different between emm 1-type and emm 12-type isolates (P< 0 .05) .Conclusion Type emm1 and type emm12 are epidemic strains in patients with scarlet fever from 2012 to 2013 in Beijing ,and emm gene-types are associated with superantigen genes profiles .

Fibroblast growth factor 23 (FGF23) is a bone-derived hormone that plays a central role in the regulation of calcium, phosphorus and active vitamin D levels. Recent studies have shown that high FGF23 is associated with cardiocerebrovascular diseases. This article reviews the correlation between FGF23 and cerebrovascular diseases.

Objective To investigate the compliance and mastery of heath education in pa-tients undergoing percutaneous coronary intervention (PCI).Methods A total of 8 patients were interviewed at 24~48 h,10 days,1 month,2,3,6,9 and 12 months after PCIby qualitative re-search.Results The compliance in medicine,rehabilitation exercise,diet,regular review and health behavior were decreased with the time lasting.Conclusion Regular revisit and proper inter-ference can improve the compliance of health education and long-term effect after PCI,decrease cardiovascular system risk events recurrence,and establish a long-term disease management mod-el.

Objective To establish a selection system for medical consumables that identifies high-quality,cost-effective products meeting hospital and operational development needs while ensuring patient satisfaction,thus promoting the scientific and rational use of medical consumables in clinical settings.Methods The current status and challenges of medical consumables se-lection management in healthcare institutions were analyzed.The approach involved clarifying overall requirements,determining management structure and regulations,establishing standardized selection processes,choosing appropriate categories for selec-tion,and setting selection criteria.This system was built upon a medical consumables procurement transaction platform and lever-aged the SPD model to create a scientifically sound and comprehensive selection system for medical consumables.Results The number of similar consumable products was reduced,with an average price reduction of over 14.63％,and clinical department satisfaction reached 90％.Conclusion Constructing a scientifically sound selection system for medical consumables helps to lower patient expenses and hospital costs,improve service quality,and align with the requirements for high-quality development in public hospitals.

Objective To investigate the antimicrobial resistance profile of the Streptococcus pneumoniae strains isolated from respiratory tract of children in Zhongshan Boai Hospital, Guangdong Province for better management of such infections. Methods The sputum samples were collected from respiratory tract of children in pediatric outpatient and inpatient from May 2013 to August 2017. S. pneumoniae strains were isolated and identified and their susceptibility to antimicrobial agentswas determined. Results The prevalence of S. pneumoniae was 10.6％ (2 963/28 006) in the sputum samples. S. pneumoniae was mainly isolated from children under 6 years old, and relatively higher in winter and spring. About 43.0％ of the S. pneumoniae isolates was associated with mixed infection, especially Moraxella catarrhalis and Haemophilus influenzae. About 6.0％ of the S. pneumoniae isolates were non-susceptible to penicillin, 59.3％ non-susceptible to ceftriaxone, and more than 95％ non-susceptible to erythromycin, clindamycin or tetracycline. However, more than 95％ of the isolates were susceptible to chloramphenicol or ofloxacin. No S. pneumoniae isolate was found resistant to rifampin, linezolid or vancomycin. Conclusions The respiratory tract infection caused by S. pneumoniae of children is increasing year by year, which is associated with age, season, and higher rate of mixed infection. These data showed that penicillin non-susceptible S. pneumoniae is highly prevalent in Zhongshan. More than 95％ of the S. pneumoniae isolates from children are resistant to erythromycin, clindamycin or tetracycline. S. pneumoniae isolates should be closely monitored for the emergence of multidrug resistant strains. Appropriate control measures must be taken according to the results of susceptibility testing.
