Objective To explore and classify the subjective opinions of nurses on whistle- blowing, and identify the subjective characteristics of each type. Methods This study applied Q -methodology, protocols which could determinate subjective opinions of nurses on histle-blowing were set up and underwent interview investigation, data of the interviews went through Q-factor analysis. Results Most nurses had a positive attitude toward whistle - blowing because it could prevent any nursing activity not based on expertise and professional ethics from causing disadvantages for patients. At the same time, however, they requested the creation of a legal framework in which whistle-blowing was done in a way to increase trust among colleagues. Meanwhile, some nurses showed resistance to whistle - blowing. Conclusions Whether whistle - blowing can reach its aims depends on nurses' attitude toward it. Most Korean nurses support whistle-blowing. Nursing activity not based on expertise and professional ethics and causing disadvantages for patients can be avoided if a legal framework is established for whistle-blowing.

OBJECTIVE:To discuss the use of allopurinol for the reduction of serum uric acid level in patients with chronic kidney disease complicating hyperuricacidemia so as to delay the progression of chronic renal disease.METHODS:A total of 47 patients with chronic kidney disease complicating hyperuricacidemia were randomly divided into treatment group and control group:the treatment group was given allopurinol 100～200mg?d-1 in addition to the antihypertensive therapy as adopted in the control group or the common therapy for 12 months.RESULTS:As compared with the control group,serum creatinine level was lower and the rate of renal function deterioration was significantly decreased in the treatment group(P

Objective To compare the effect of methotrexate combined with laparoscopic surgery on pregnancy outcome of patients with tubal pregnancy treated with conservative treatment.Methods 96 patients who were diagnosed of tubal pregnancy,fertility requirements and no clinical data given birth were analyzed retrospectively.Depending on the method of treatment was divided into 46 cases of methotrexate and laparoscopic group of 50 patients.Postoperative intrauterine pregnancy,ectopic pregnancy and secondary infertility situation again were compared.Results Laparoscopic group in intrauterine pregnancy rate was 70.0％,which was significantly higher than that in the methotrexate group(47.8％),and the difference was statistically significant(x2 =13.229,P ＜ 0.05) ;laparoscopic ectopic pregnancy rate was 14.0％ against 17.4％ with methotrexate group,the difference was not statistically significant(x2 =2.037,P ＞ 0.05) ; methotrexate group was 34.8％ of secondary infertility was significantly higher than thatin the laparoscopic group (16.0％),the difference was statistically significant (x2 =12.784,P ＜ 0.05).Conclusion Laparoscopic surgery after conservative treatment of tubal repregnancy outcome is better than methotrexate.

BACKGROUND:Class II malocclusion is commonly observed in clinics, with the main manifestation of skeletal malocclusion, and mandibular retrusion is the main reason. Class II malocclusion should be treated early to correct skeletal malformation and improve facial appearance. OBJECTIVE:To compare the biomechanics change in early treatment of Class II division 1 malocclusion with Twin-Block appliance and straight wire appliance combined with face-bow and Class II drawing. METHODS: Thirty patients with malocclusion who were at peak velocity on the growth curve were randomly divided into two groups, with 15 cases in each group. Patients in each group were treated with Twin-Block appliance and straight wire appliance combined face-bow and Class II drawing, respectively. The cephalometric records of al patients were examined before and after the treatments. The acquired data were processed by statistical analysis. RESULTS AND CONCLUSION:After treatment, al molars and cuspid teeth achieved or reached Class I, and ANB angle decreased to normal range. The bone effect of Twin-Block appliance was more significant than straight wire appliance. Using Twin-Block appliance, the length of mandible body and lower face height increased significantly. Experimental findings indicate that, Twin-Block appliance has significant therapeutic effects in treatment of early skeletal Class II division 1 malocclusion patients, who are at peak velocity on the growth curve. With the biomechanical effects, this treatment corrects asymmetrical jaw relation, reconstructs the tissue, and obtains satisfactory lateral facial profile of soft tissues. The therapeutic effect is more obvious for patients with obvious mandibular retrusion, flared upper incisors and upright lower incisors.

Objective To determine the factors influencing the indication for tracheostomy following cervical spinal cord injury.Methods A retrospective study was performed to analyze the 118 patients who had been treated for cervical fracture/dislocation along with cervical spinal cord injury from July 2004 to June 2014 and whose abbreviated injury scale score (AISS) was lower than 3.They were 96 men and 22 women,19 to 68 years of age (average,45.2 years).The patients were divided into a tracheostomy group (n ＝ 28) and a non-tracheostomy group (n =90).The 2 groups were compared in terms of gender,age,presence or absence of complete spinal cord injury at admission,injured segment,injury mechanism,smoking history,injury severity score (ISS),motor AISS,systolic pressure at admission,hospital stay,and ICU stay to determine the factors influencing allocation of tracheostomy.Results Compared with the non-tracheostomy group,the tracheostomy group had a higher rate of complete spinal cord injury at admission,a higher rate of smoking,a higher ISS at admission,a lower motor AISS,and longer hospital and ICU stay,with statistically significant differences (P ＜ 0.05).There were no significant differences between the 2 groups in gender,age,injured segment,injury mechanism,or systolic pressure at admission (P ＞ 0.05).Increased severity of cervical spinal cord injury was associated with significantly decreased motor AISA,increased rate of tracheostomy and increased ISS (P ＜ 0.05).Conclusion The influencing factors for indication of tracheostomy after cervical spinal cord injury are complete cervical spinal cord injury irrespective of the level of injury,ISS,motor AISS,and history of smoking.

Objective: The effect of whole body irradiation (WBI) on B7-1 and B7-2 express ion in peritoneal macrophages in mice was observed.Methods:Immunohistochemistry (ABC method) was used. Results: The upregulation of B7-2 expression induced by WBI X-rays appeared ea r lier than that of B7-1.The study on the dose-effect relationship showed that t he ex pression of both B7-1 and B7-2 reached its peak at 0.075 Gy after WBI X-rays. Th e doses inducing a second peak of B7-1 and B7-2 upregulation were higher in th e case of WBI in comparison with in vitro irradiation. Conclusion: The results suggested that the upregulation of expression of B7 mole cules after irradiation might be an important factor involved in the enhancing e ffect of low dose radiation on immunity.
