OBJECTIVE To discuss the effect of the central sterilization and supply center in controlling the infection in hospital.METHODS Eliminated the old supply pattern,to implement centralized management for the supply office.The whole sterilization and supply center was rebuilded according to the standard,cleared the function,standardized the procedure and strengthened the management.RESULTS The centralized sterilization and supply center could form effective and standard circulatory system for cleaneiness,sterilization and antiseptic,and ensure the quality of disinfectants.CONCLUSIONS The centralized sterilization and supply center is better to the management and control of quality, it can reduce the pollution,simplify operational procedures,reduce hospital infection,and realize the zero flaw of aseptic goods.

Objective To compare the distribution and drug resistance of isolates between sterile body fluid and non‐sterile body fluid in the hospital in 2014 .Methods By adopting the retrospective analysis method ,we used BD phoenixTM 100 to conduct bacteria identification and drug susceptibility testing ,the Whonet5 .6 software and SPSS19 .0 software to statistically analysize the drug re‐sistance of the bacteria .Results E .coli ranked the top in sterile body fluid isolates(43% ) while the highest rate in non‐sterile body fluid was P .aeruginosa .E .coli(21% ) .Isolates from sterile body fluid had lower drug resistance rate to 11 kinds of antibacterials such as ampicillin ,chloramphenicol ,ciprofloxacin and aztreonam than the strains isolated from non‐sterile body fluid(P<0 .05) .S . aureus ,isolated from sterile body fluid ,had lower drug resistance rate to 6 kinds of antibacterials such as amikacin ,amoxicillin/cla‐vulanicacid ,ciprofloxacin than the strains isolated from non‐sterile body fluid .P .aeruginosa ,isolated from sterile body fluid ,had lower drug resistance rate to aztreonam than the srains isolated from non‐sterile body fluid .K .pneumoniae ,isolated from sterile body fluid ,had lower drug resistance rate to 6 kinds of antibacterials such as ampicillin/sulbactam ,sulfamethoxazole ,chlorampheni‐col than the strains isolated from non‐sterile body fluid(P<0 .05) .Conclusion There is significant difference between sterile body fluid and sterile body fluid in strain distribution and drug resistance ,so it is vital to enhance the bacterial resistance surveillance of sterile body fluid .

Objective To investigate the healthy adults in Heyuan area of serum N terminal pro brain natriuretic peptide (N‐proBNP) concentration distribution and the preliminary investigation on the normal reference range .Methods From 2010 Novem‐ber to 2012 November in the physical examination ,laboratory examination center of our hospital indicators ,ECG ,B ultrasound ex‐amination showed no abnormalities of the healthy people 1 017 ,according to the different gender and age :A group less than 25 years ,group B was 25- <35 years ,35- <45 years ,group C ,group D 45- <55 years ,55- <65 years of E group ,F group for over 65 years a total of 6 age groups ,content determination of serum N‐proBNP by Roche chemical instrument light .Results age ,gen‐der can affect the distribution of N‐proBNP level ,and with the increase of age ,adjacent to the age groups (except F group) to com‐pare the serum levels of N‐proBNP ,the difference was statistically significant (P<0 .05);Compared with the F group in each age group was significantly increased(P<0 .05) ,there was statistical significance compared with the group ;the serum N‐proBNP level of different sex ,the difference was statistically significant (P<0 .05) .Conclusion age ,gender and other physiological factors can affect the distribution of N‐proBNP levels ,should establish the corresponding reference interval according to the different age ,gen‐der ,provide the corresponding parameters for the diagnosis and treatment of related diseases .

AIM:To investigate the autophagy induced by sepsis and acute kidney injury , and the regulation of phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway in this process.METHODS: The rats were subjected to cecal ligation and puncture ( CLP) or sham operation .Histopathologic changes of the renal tissues were examined by HE staining .Blood urea nitrogen ( BUN) and serum creatinine ( SCr) were measured by chemical colorime-try.The protein expression of microtubule-associated protein light chain 3 I/II (LC3 I/II), beclin-1 and p-Akt at different time points after CLP was detected by Western blotting .In vitro, human proximal tubular epithelial cell line HK-2 were treated with LPS to induce autophagy .The protein expression of LC 3 I/II and p-Akt in the HK-2 cells after LPS treatment at different time points and different concentrations was detected by Western blotting .These molecules in HK-2 cells and apoptosis of HK-2 cells treated with LPS plus PI3K inhibitor or Akt inhibitor were also detected .RESULTS: Compared with sham group , the severe changes of renal histopathological injuries in CLP groups were observed , the levels of BUN and SCr in CLP groups were significantly increased .LC3 I/II, beclin-1 and phosphorylation of Akt gradually increased after CLP.After treatment with LPS, the expression of p-Akt (308) in the HK-2 cells gradually increased in a dose-and time-dependent fashion.The expression of beclin-1 and p-Akt (472) reached a peak at 8 h or 10 mg/L LPS treatment.Treat-ment with PI3K or Akt inhibitor down-regulated the expression of LC3 and promoted the apoptosis of HK-2 cells.CON-CLUSION:Autophagy in the kidney is induced by sepsis and acute kidney injury .PI3/Akt signaling pathway may be in-volved in this process .

Objective:Discuss and analyze the mechanisms of spine fine adjusting through the observation of the therapeutic effect in treating cervical spondylotic radiculopathy(CSR)and the conversion of cervical curvature.Methods: Randomly divide 106 CSR patients into two groups–manipulation therapy group and traction therapy group,53 for each.Judge the therapeutic effect by evaluation scales and measure the cervical curvature on X-ray photographs.Results:The symptoms and physical signs of the patients in both two groups have been improved(P

Objective To evaluate the prevalence of chronic kidney disease (CKD) in Chinese adult health check-up population,and to compare with the prevalence of CKD in the study of the general population as well as the large CKD cross-sectional study in China.Methods Epidemiological studies about CKD in Chinese adults health check-up population from January 2007 to December 2017 were searched in PubMed,SinoMed,CNKI,VIP and Wanfang Data.Meta-analysis of the prevalence of CKD was performed with software of Stata 12.0.Subgroup analyses of CKD staging,urban and rural,as well as geographical areas of the general population were executed.Results Twenty-two studies from adult health check-up population were included (238 349 persons).Egger's regression showed no publication bias (P ＞ 0.05).The unstandardized prevalence rate of CKD was 12.49％ (male 12.8％,female 12.5％).The respective unstandardized prevalences of proteinuria,hematuria and eGFR decline were 5.90％,5.83％ and 2.75％.The unstandardized prevalences of CKD in urban and rural population were 13.21％ and 11.90％.The stages of CKD were mainly concentrated in the early stages.There was no significant difference in the non-standard detection rate of total eGFR decline among the adult medical examination population,the general population and the population studied cross-sectionally (P ＞ 0.05).Furthermore,no significant difference in the non-standard detection rate of total hematuria and male hematuria was found between the adult health check-up population and the general population.In addition,the total proteinuric non-standard detection rate of the adult general population was similar with that of population studied cross-sectionally (P ＞ 0.05).Conclusions The prevalence of CKD in Chinese adults is higher,the overall prevalence is however underestimated.The results of epidemiological investigation in adult health check-up population are similar to those of the general population,especially in men.
