One hundred and eighty three women with high risk of breast cancer identified in Baoding First Central Hospital from June 2007 to June 2014,were enrolled in the study.In these 183 cases,41 received preventive therapy (22.4％),142 did not.Factors associated with acceptance of chemoprevention included older age,menopause,comorbidities,lower level education,being married,higher BMI,having high level hyperplasia of ductal epthelia and counseling to breast specialists (P ＜ O.05);whilenot informed by doctors was the main reason for failed taking preventive agents(95.1％,135/142).Thirteen of 41 women receiving chemoprevention discontinued the therapy (31.7％);no-insurance,no side-effects and higher BMI were related to the discontinuing (P ＜ 0.05).The 1-,2-,3-,and 5-year adherence rates of chemoprevention was 86.1％ (31/36),65.4％ (17/26),59.1％ (13/22),8/13 and 5/10,respectively.The results show that chemoprevention rate is low among Chinese women at high risk of breast cancer,and the long-term adherence to preventive therapy is poor.Corresponding measures should be taken to strengthen the chemoprevention of breast cancer.

OBJECTIVETo apply the Wright-Giemsa stain in micronucleus test and to explore the stain outcomes of Wright-Giemsa dye of various proportions and staining times.

METHODSUse Wright-Giemsa dye, Wright dye (staining time 3 min) and Giemsa dye (staining time 5 min) to stain HepG2 and then observe the staining effect. The Wright-Giemsa dye was applied under 5 different proportions (3:1-1:3) and different staining times (1, 3, 5, 10, 15 min).

RESULTSAfter stained for 3-5 min with the proportion ratio of 3:1 of Wright-Giemsa dye, the HepG2 cells showed much better staining outcomes compared with the single stain of either Wright or Giemsa.

CONCLUSIONSWright-Giemsa stain can be used in cell micronucleus test to obtain good staining outcomes.

Objective To investigate the classification of major bacteria and pathogen strains before and after inner tubes disinfection within the trachea after the tracheotomy, and to compare the method of disinfection and the results. Methods 110 patients after tracheotomy were randomly selected, and tracheal tubes were sampled before the disinfection and were conducted a bacterial culture analysis. These tracheal tubes were disinfected by boiling for 20 minutes and 30 minutes, respectively. Then they were soaked in 75% ethanol, 2% glularaldehyde and 3% hydrogen peroxide for 20 minutes and 30 minutes, respectively. The disinfection effects were compared among the four disinfection methods and disinfectants, and the two groups of disinfection time. Results 62 cases before the disinfection were sampled to make a bacterial culture. 89 strains in 18 species were cultivated, and no bacteria in six cases. Pathogenic bacteria and conditioned pathogen accounted for 80 percent (P<0.05). For the four disinfection methods including boiling disinfection, 75% ethanol, 2% glutaraldehyde and 3% hydrogen peroxide immersion disinfection, after 20 minutes of disinfection and immersion disinfection, 75% ethanol immersion disinfection had statistical meanings with the positive rates of boiling disinfection, 3% H2O2 and 2% glutaraldehyde soaking disinfection, respectively (P<0.05) ; After 30 minutes of disinfection, all of the four disinfection methods had no statistical meaning. Conclusions Pathogenic bacteria cultivated before the disinfection of tracheal tubes are much more than the non-pathogenic bacteria. Boiling disinfection for 20 minutes, 3% hydrogen peroxide and 2% glutaraldehyde disinfectant soaking for 20 minutes, and 75% ethanol immersion disinfection for 30 minutes can achieve good disinfection results. From the aspects of high efficiency, safety and low cost, 3% hydrogen peroxide is the best choice.

Objective To survey the status of health-promoting lifestyle among the clinical head nurses. Methods A total of 135 head nurses from 4 Grade-A hospitals in Shenzhen City were surveyed with the health-promoting way of life scale and general information questionnaire. Results The overall life level of the four hospitals nurses was (132.63 ±19.40)points; in the six sub-scales, the interpersonal relationship was the highest (25.37 ±4. 03) points, followed by self-realization (25.6 ±4. 15) points, the worst is the phsical exercise (17.08 ±4.69) points, stress management (20.05 ±3.71) points. Conclusions The head nurses pay less attention to the of health-promoting lifestyle. The Department of nursing management should guid and stimulate the potential of the head nurse to perform the positive health behavior become the real social role model.

Objective To observe the oral part of the facial artery and facial vein and to provide anatomical data for clinical applica-tion. Methods The origin, branches, course, diameter, position of oral part of facial artery and facial vein were observed on 32 fixed cada-ves (64 sides). Results The position relation between the facial artery and facial vein is non-constant. Measure the distance from inferior border of mandible to corner of the mouth, angulus mandibulae, mental protuberance midpoint. It is (5. 49 ± 0. 63) cm, (2. 50 ± 0. 89) cm and (6. 20 ± 1. 68) cm in the left side respectively, and (5. 69 ± 0. 72) cm, (2. 56 ± 1. 08) cm and (6. 85 ± 1. 86) cm in the right side re-spectively. The diameter of facial artery in inferior border of mandible is (0. 33 ± 0. 08) cm in the left side and (0. 38 ± 0. 07) cm in the right side;while the diameter of facial vein is (0. 40 ± 0. 12) cm in the left side and (0. 42 ± 0. 18) cm in the right side. The facial artery and facial vein are not concomitant and they are not asymmetry also. The position of superior labial artery arteries is constant, but the position of inferior labial artery arteries have more variations. Conclusion The branches, course, diameter and position of oral part of facial artery and facial vein have a number of variations. The superior labial artery arteries could be positioned more easily than inferior labial artery arter-ies. Being familiar with their distribution is of great importance for clinical application.
