Objective To detect bacterial content on surface of mobile phones of health care workers (HCWs)by adenosine triphosphate (ATP )bioluminescence assay.Methods HCWs in departments of internal medicine,surgery, medical laboratory,and administration were randomly selected,50 in each department,field detection on bacterial content on surface of mobile phones of HCWs was conducted,the relevant data were recorded.Results A total of 200 mobile phones were detected,33 mobile phone surface were qualified,the qualified rate was 16.50%.Qualified rate of mobile phone surface of HCWs in different departments as well as mobile phone disinfected by different modes were different(χ2 =13.46,10.24,respectively,both P <0.01);difference in qualified rate of mobile phones of different types,different service life,and different protective case were all not significant (χ2 =4.37,1 .87,0.25 respectively,all P >0.05).Conclusion The qualified rate of bacterial content on surface of HCWs’mobile phone is low,the awareness of hand hygiene of HCWs should be strengthened,regular cleaning and disinfection on the mo-bile phone can effectively reduce bacteria on the mobile phone surface.

Objective To investigate healthcare-associated infection(HAI)prevalence and antimicrobial use in a hospital.Methods HAI prevalence rate,antimicrobial use and pathogen detection in all inpatients on August 21 , 2013 were investigated with cross-sectional survey method.Results A total of 2 238 inpatients were investigated, 104 patients developed 126 times of HAI,HAI prevalence rate and case rate was 4.65% and 5.63% respectively;the top four sites for HAI were lower respiratory tract (28.57%),upper respiratory tract(18.25%),urinary tract (7.94%)and gastrointestinal tract(4.76%).Rate of specimens delivered for detection was 91 .35%(95/104),the main specimen was sputum (26.32%),followed by blood (25.26%)and urine (10.53%).Antimicrobial usage rate was 24.58%,therapeutic,prophylactic plus therapeutic,and prophylactic use accounted for 36.55%,45.09%, and 18.36% respectively;the usage rate of single,combination of 2,and 3 antimicrobial agents accounted for 75.82%,20.91 % and 3.27% respectively.Risk factors of HAI were age (<15 or >60 years),all kinds of inva-sive procedures (tracheotomy,mechanical ventilation,urinary catheterization,arteriovenous intubation,hemodialy-sis),and anti-tumor chemotherapy.Conclusion Survey on HIA prevalence helps to know the occurrence of HAI and usage of antimicrobial agents,as well as risk factors and high-risk departments of the occurrence of HAI,it also provides basis for subsequent targeted monitor on HAI.

Objective:To study the dissolution behavior of panax notoginseng saponins R1 , ginseng saponin Rg1 and ginseng sapo-nin Rb1 in Xuesaitong soft capsules in two different dissolution media. Methods:The dissolution test conditions were confirmed accord-ing to“quality of medical drugs information set” of Japan and the dissolution media were chosen in accordance with the physicochemi-cal properties of Xuesaitong soft capsules, the in vitro dissolution of Xuesaitong soft capsules was inspected respectively in pH 6. 8 phosphate buffer and water. The dissolution rate was determined by HPLC-ELSD, and the similarity of the release curves for the three components was compared with similarity factors ( f2 ) method. Results: The assay displayed a good linearity over the concentration range of 0. 8-16. 0 mg·L-1(r=0. 999 6), 3. 0-60. 0 mg·L-1(r=0. 999 8) and 4. 0-80. 0 mg·L-1(r=0. 999 7) for panax notog-inseng saponins R1 , ginseng saponin Rg1 and ginseng saponin Rb1 , respectively. In pH 6. 8 phosphate buffer and water, f2 of ginseng saponin Rg1 and ginseng saponin Rb1 were both above 50 when compared with panax notoginseng saponins R1 . Conclusion:The meth-od is simple, accurate and reproducible in the dissolution determination of the soft capsules. The dissolution of ginseng saponin Rg1 and ginseng saponin Rb1 has similar characteristics with that of panax notoginseng saponins R1 in Xuesaitong soft capsules.

The immunoregulation effect to polysaccharides from Bifidobacterium spp. was investigated on the base of functional assessment standards of health food. Effects of the EPS on immunity were investigated by promoted the proliferation of spleen lymph cells, delayed type hypersensitivity reaction, the HC50 value and macrophage function assay in mice. Data showed that the EPS could obviously increase the ratio of swallowed chicken red blood cell by macrophage and the HC50 value in mice. However, no significant effect was found on the delayed type hypersensitive induced by sheep red blood cell, for only the low dose of 100 mg/(kg?d) EPS promoted the proliferation of spleen lymph cells. Bifidobacterium spp. EPS can certain immunomodulating function.

To obtain a most appropriate method for the evaluation of the three basic skills of clinical doctors,we designed an objective structured clinical examination(OSCE) model with standardized patients and applied it to the "three-basic" examinations among 50 doctors from various clinical departments.The results showed that this model provided a new way for the effective,objective and reliable evaluation of doctors' clinical knowledge and skills.

Objective To study and contruct competency characteristic evaluation models of nursing supervisors in secondly hospitals.Methods Using the matron semi-structured interviews,literature review,questionnaire survey and expert questionnaires to discuss the competency of nursing supervisors in secodary hospitals.Results We found that the competency model of nursing supervisors in secondary hospitals could better reflect the competency of nursing supervisors.The model had 16 competencies which included knewleage skills.management and individual characters.Conclusions Through the study of the model of competency nursing supervisors in secondary hospitals,we form a set of standard for nursing supervisor selection based on their competency.The standard can help to select the most suited nursing supervisors who have great potentials.
