Objective To investigate risk factors for healthcare-associated infection(HAI)in patients with craniocerebral operation,and provide reference for the prevention and control of HAI.Methods A total of 4 246 cases of craniocerebral surgery in a neurosurgery department from January 2010 to December 2012 were enrolled in the study,the risk fac-tors for HAI were analyzed.Results Of 4 246 cases of craniocerebral surgery,393 patients developed 446 times of post-operative HAI,HAI incidence rate was 9.26%,case infection rate was 10.50%,which were higher than inci-dence (2.02%)and case infection rate (3.02%)of HAI of all hospital during the same period,the difference was statistically significant (χ2 =811 .06,629.30,respectively,P <0.001).The major infection site was central nervous system (56.50%),followed by respiratory system (27.36%).Unconditional univariate logistic regression analysis showed that sex,age,community-acquired infection,primary disease,operative time,length of stay in intensive care unit (ICU)before infection,the number of surgery,invasive procedures and nasogastric tube,the difference was statistically significant (all P <0.05 ).Multivariate logistic regression analysis showed that sex,elderly pa-tients,congenital brain diseases,stay in ICU>7 d,antimicrobial use >7 d,central venous and urinary tract cathe-terization,invasive ventilator were risk factors for HAI in patients with craniocerebral operation.Conclusion The incidence of HAI in patients with craniocerebral operation is high,effective preventive and control measures accord-ing to risk factors should be strengthened to reduce the incidence of HAI.

OBJECTIVE To confirm the clinical disinfection effect of acidity electrolyzed oxidizing water(AEOW).METHODS According to the standards of disinfection techniques supplied by Health Ministry of China,the disinfection effect of health care worker,object surfaces and medical apparatus and instrument were investigated.RESULTS The log reduction of the bacteria on the hands,object surfaces and medical instruments were more than 1.00.The number of the bacteria on the endoscopes were 0-2 CFU per piece on average.No pathogenic bacteria were detected out.The disinfection effect of each experimental group was qualified.CONCLUSIONS The field disinfection effect of AEOW is accepted.

OBJECTIVE To explore the effect of the nanometer photocatalysis air disinfector.METHODS The air disinfection effect of nanometer photocatalyis air disinfectior JBL-400 series,such as the self-cycling movable,mosaic and attached to the wind gap air disinfectors,was detected in the simulating field trial and field trial in intensive care units,operating rooms and therapy rooms according to the Disinfection Technique Standards.RESULTS The kill ratio of self-cycling air disinfector in simulating trial was more than 99.9%.After constant air disinfection in the above three kinds of medical divisions,the total bacteria number of static state in these places could reach to the standard of area Ⅱ(≤200 CFU/m3),with 56.8-78.4% dissolution ratio of the natural bacteria.The total bacteria number of dynamic state in these places could reach to the standard of area Ⅱ or area Ⅲ.CONCLUSIONS The JBL-400 series air disinfector has diverse application forms,and disinfects quickly with good effects.It can be used in all kinds of medical divisions.

OBJECTIVE To probe into the new method to improve medical environment,and reduce hospital infection causing by the environmental factors.METHODS Using the nanometer photocatalysis technology clinically,to analyze the bacteriostatic effect of medical environment.RESULTS After use of the nanometer photocatalysis spraying material the surface sterilization effect was obvious on the three kinds of environmental objects.The withering away rate of bacterium on the object with total surface was 23.75-38.30%;the vertical surface bacterium withers away rate was 48.77-87.97%,the horizontal surface bacterium withers away rate was 12.50-77.20%,the air bacterium withering away rate was 1.52-60.00%.CONCLUSIONS The nanometer photocatalysis technology to sterilize and purify the medical environment has very good perspectives.

OBJECTIVE To study the degree and regular of Aspergillus flavus air contamination in hospital.METHODS Some ambient air of different environment in our hospital was taken 5 times in one day of four seasons one year by using centrifugal air sampler,and then cultivated(using eumycete cultural methods),counted and analyzed.RESULTS A.flavus strain was collected in all sampling points in four seasons.The concentration of Aspergillus flavus in six standort was diverse from each other,and the highest was the out-patient clinic with 1238.9 CFU/m3.The concentration of Aspergillus flavus in each division of Medical Department was significant difference during four seasons(P0.05).The difference between internal medicine and external enviroment was significant between the first and the third season(P=0.022,P=0.039),but that of the second and the fouth season was not significant(P=0.022,P=0.624).CONCLUSIONS The contamination of Aspergillus flavus in hospital was severe.So it′s necessary to prevent the Aspergillus flavus infection and enhance the environmental control of susceptible population.

OBJECTIVE In order to prevent and control the nosocomial infection effectively by hospital construction design scientifically.METHODS The theory and the practical application of hospital construction,were analyzed and discussed to prevent the nosocomial infection.RESULTS The hospital construction was fundamental in preventing and controlling nosocomial infection.It could control exogenous nosocomial infection.Through scientific and effective isolation,the hospital construction could help to control source of infection,cut off infection routin and protect the susceptible population.CONCLUSIONS Hospital construction design should conform to the principle of nosocomial infection precention and control.

Objective:To probe the exploration and integration of ideological and political teaching resources for College English by medical students' teams, and to build a College English ideological and political teaching resource database in medical colleges, so as to provide feasible experience for the integration of medical students' College English and ideological and political education.Methods:A questionnaire survey was conducted among 1 030 students in a medical college, and SPSSAU statistical software was employed to analyze the results to investigate the attitudes and demands of students towards the integration of English teaching and ideological and political education, the construction methods of College English ideological and political teaching resource database, and the presentation methods and types of resources. Based on the questionnaire results, textbook themes, teaching modules and students' majors, the content analysis and classification method were employed to construct a College English ideological and political teaching resource database that meets the expectations of medical students.Results:① A total of 836 students agreed with the necessity to integrate College English with ideological and political education, hoping to build an ideological and political resource database with videos and audios related to daily life ( n = 731), medical knowledge ( n = 664), social practice ( n = 622), news and current affairs ( n = 604) and guide the students to learn the above resources through the methods "teacher instruction + classroom discussion" ( n = 528). ② The ideological and political integration points in the questionnaire results were matched according to the subjects of the textbook, and further divided into two categories: universal and medically specific ideological and political teaching elements according to the content of the unit modules. Finally, the resource database of College English ideological and political teaching in medical colleges was built. Conclusion:Outstanding courses and resources are jointly explored and built by teachers and students.
