OBJECTIVE To approach the method for continuing improvement of quality control in cleaning and disinfection.METHODS Looked for the problems in the process of cleaning and disinfection of endoscope,and the reasons wereanalyzed.The specific measures for continuing improvement of quality control in cleaning and disinfection of endoscope were formulated and fulfilled.The examining norms of nursing quality were modified,and the surveillance management of the quality control and the cleaning and disinfection of endoscope were enhanced.RESULTS For continuing improvement of quality control in cleaning and disinfection of endoscope,the total quality of nursing service must be enhanced.CONCLUSIONS For one year practice,we found that continuing improvement of quality control in cleaning and disinfection fo endoscope could enhance total quality of nursing care,and ensure medical treatment safety while decreasing onset of hospital infection.

Objective To detect the changes in cTnI and CK MB during extracorporeal circulation and the myocardial injury by extracorporeal circulation. Methods The value of cTnI and CK MB was determined in 30 persons during extracorporeal circulation. We divided them into 6 groups according to pre operation, 6, 12, 24, 48 and 72 hours after operation. Modified method (Bodor et al) was used to detect cTnI, and immune suppression method to detect CK MB. Results cTnI and CK MB were, cTnI ( ?s ) (5.20?2 80) ?g/L,CK MB ( ?s ) (10.75?4.70) U/L in 28 persons. They elevated 6 hours after operation. 12 24 hours after operation cTnI and CK MB increased to the maximum, cTnI 28.80 71.30 ?g/L,CK MB 55.60 71.30 U/L. During 48 72 hours, CK MB decreased to normal, 49.70 22.80 U/L. cTnI was 9.40 19.80 ?g/L 72 hours after operation. Conclusion Extracorporeal circulation may cause myocardial diseases. cTnI is a more sensitive biochemical marker for myocardial diseases.

Objective A large number of traditional Chinese medicine(TCM)are widely used for the treatment of patients with cerebral hemorrhage in China. The aim of this study is to systematically review the existing clinical evidences on TCM treatment for cerebral hemorrhage. Methods Randomized controlled trails(RCTs) of TCM treatment of cerebral hemorrhage were identified, eligible studies were included, the methodological quality of inclusive trails was assessed by the modified Jadad scale. The Cochrane Collaberation’s Revman 5.20 was used for data analysis. Results 69 RCTs were available and included. Meta-analysis indicated that relative risk of overall effective rate of Sanqi, Ciwujia, Chuanxiongqin and Naoxueshu were significant difference; SMD(95% CI) of neural function defect score was SMD=-0.46, 95%CI(-0.56,-0.35)of Sanqi, Danshen, Qingkailing, Liangxuetongyufang;SMD(95%CI) of the reduce of cerebral hemorrhage was SMD = -0.98, 95% CI(-1.32, -0.63)of Danshen, Dahuang, Ciwujia, Qingkailing, Liangxue-Tongyufang. Conclusions The evidence currently available showed that the TCM which included do not increase the death rate and adverse reaction of the patients with cerebral hemorrhage, TCM could reduce neurological deficit and improve the absorption of hematoma.

Objective:To study the movement regularity of Ca~(2+) in tooth hard tissue.Methods:14 extracted intact caries-free teeth were cleaned and then immersed into artificial saliva in a divice with 3 chambers for enamel part,dentin part and cement part respectively.The concentration of Ca~(2+) in the chambers was measured with an ion meter,TECHNICON(AXON,USA),24 h after immersion of each tooth.Results:The Ca~(2+) concentration in tooth immersed fluid of enamel part was higher than that of dentin part(P

OBJECTIVE To study the changes in drug resistance and distribution of Pseudomonas aeruginosa to guide drug treatment in clinic.METHODS P.aeruginosa was identified by API and VITEK2 system,and its antimicrobial ressistance was determined by Kirby-Bauer method.The antimicrobial ressistance rates were analyzed by WHONET 5.4 software.RESULTS The resistance of P.aeruginosa to 12 antibiotics was increased in the past nine years.The resistant rate to meropemem,imipenem,ciprofloxacin and ceftazidime was below 30%.Among 2127 strains of P.aeruginosa,94 strains were identified multi-drug resistant and found more frequently in ICU,and Respiratory Department.CONCLUSIONS P.aeruginosa is resistant to many kinds of antimicrobial agents,and resistant rate is increasing year by year.In order to control and slow down the occurrence of the resistant strains,it should be more careful to choose antimicrobial agents according to the antimicrobial susceptibility test.

Objective To introduce Checklist Individual Strength(CIS)into China,and evaluate its reliability and validity.Methods CIS was translated into Chinese language and the reverse translation was done by several experts.Validity and reliability were implemented in 214 cases with cerebral infarction.Results 4 components were extracted in factor analysis,and the total cumulative contribution was 78.984%.By correlation analysis,the twenty items were divided into 4 domains:subjective feeling of fatigue,concentration,motivation and physical activity,it was same as in the English version.Cronbach α of four domains were 0.9256,0.9072,0.7598,and 0.9157,respectively.Conclusion Psychometric properties(reliabilities and validities)of CIS Chinese version is met with satisfaction and seems to be adaptable to Chinese cerebral infarction patients.

Objective To analyze the instruments for post stroke fatigue, Fatigue Severity Scale (FSS)，Checklist Individual Strength (CIS) and Fatigue Impact Scale (FIS). Methods The FSS，CIS and FIS were applied in 214 cases with cerebral infarction. They were combined together at the (sub)scale level, and evaluated with Mokken Scale Analysis for Polytomous Items, for validity and reliability. Results and Conclusion Three scales were and The combined scale proved to be acceptable (H>0.5). 3 components were extracted in factor analysis, and the their total cumulative contribution was 77.504%, with reliability (α) of 0.8097，0.7094 and 0.8019 respectively. FSS put emphasis on the fatigue experiences of stroke patients, CIS on the influence of fatigue on, and FIS on the social function.

Objective To evaluate the safety of endoscopic ligation of gastric and colic full-thickness wall with nylon loops.Methods Endoscopic ligation of full gastric and colic wall with detachable nylon loops, assisted by laparotomy, were performed in 4 dogs.Ligation healing was assessed on 3, 7, 10and 17 days after the procedure.Results All animals recovered after the procedure, without any clinical signs of infection or hemorrhage.Postoperative examination did not reveal gastric or colonic perforation, or local abscess.Loop ligature showed ulcer-like lesion.Histopathology revealed muscularis propria disruption, granulation tissue bridging the site of ligation and formation of scar tissue.Regenerative mucosa coyered the surface of the ligature completely 17 days after the operation.Conclusion Endoscopic ligation of gastric and colic full-thickness wall with detachable nylon loops is safe.Its application can be extended to other fields.

Objective To investigate the dynamic changes of infectious distribution,current resistant situation of Streptococcus pneumoniae(SP) and resistant to penicillin and other 10 kinds of antibiotics for the guidance of clinical therapy of SP.Methods Bacteria were identified by French BioMerieux API identification system,VITEK 2-COMPACT identification system and Optochin test,bile solubility test.In vitro,drug susceptibility test to penicillin,cefotaxime,and other 10 kinds of antibiotics were conducted with K-B disk diffusion method combined with the concentration gradient method.Drug susceptibility results were analyzed from 2001 to 2011.Results In recent 11 years,SP antimicrobial resistance rate had increased year after year,especially rates of penicillin-resistant and penicillin not-sensitive had increased significantly,rising from 8.3％( in 2001 ) to 72.7％ ( in 2011 ) ( meningitis 86.4％,non-meningitis 59.0％ ).Resistance rate of cefotaxime,belonging to third-generation cephalosporin had already accounted for 54.0％ ( meningitis 64.0％,non-meningitis 44.0％ ) ;and the resistance rate of macrolide antimicrobial was 100％ ; vancomycin-resistant strains and linezolid-resistant strains had not been detected.Conclusion Penicillin non-susceptible SP has accounted for a high percentage,antimicrobial resistance of Streptococcus pneumoniae penicillin,cephalosporins,macrolides are in serious condition.Vancomycin and linezolid should be preferred or the right antibiotics be chosen according to vitro susceptibility results of isolates in clinical treatment of severe infections caused by SP.
