Objective To identify major factors which affect the completion quality of projects and build predictive models,and to propose strategies and suggestions for total process quality management of clinical research projects of the hospital.Methods Collect relevant literatures from home and abroad;consult completion reports of various research projects completed from 2003 to 2010 and sum up problems found in such projects.Carry out in-depth interviews with principal investigators,supervisors of scientific research of the hospital as well as administrators of sponsor institutions.A questionnaire survey was made on completed clinical research projects undertaken from 2003 to 2010.Results Six key factors affecting implementation of such projects were derived from factor analysis,which are research technology and external environment,project teamwork,research subject availability,project organization,manpower input,and research design.A multiple logistic regression analysis found project internal management and manpower input as two leading predictive factors for project completion outcomes,while the former has a greater impact than the latter.Conclusion Project management should focus on the 6 key factors affecting project quality.The two main predictive factors should attract greater attention and resources in both supervision and management.

Objective To analyze the risk factors of Gram‐negative bacterial blood‐stream infection in ICU for conducting the risk evaluation and guiding medication .Methods The inpatients were diagnosed with Gram‐negative bacterial blood‐stream infec‐tion in ICU of the Renmin Hospital of Wuhan University from January 2013 to December 2014 were retrospectively surveyed and analyzed .The risk factors of blood‐stream infection caused by Gram‐negative bacteria were analyzed and screened by the Logistic re‐gression analysis method .Results A total of 172 case‐times of blood‐stream infection occurred in ICU during this period ,including 93 case‐times of Gram‐negative bacterial infection .The Gram‐negative pathogenic bacteria were Acinetobacter baumanii ,Klebsiella pneumoniae ,Acinetobacter calcoaceticus baumanii ,E .coli ,pseudomonas aeruginosa ,etc .Except E .coli was mainly originated from community acquired infection ,other bacteria were mainly originated from nosocomial infection .In order to differing from other pathogenic bacterial blood stream infection ,the Logistic regression analysis results showed that the independent risk factors of G‐negative bacterial blood‐stream infection in ICU had serum PCT levels over 10 .0 ng/mL (OR= 60 .52 ,P= 0 .001) ,receiving the therapy of carbapenem and third generation cephalosporins (OR=16 .09 ,P=0 .03) ,hospitalization duration less than 2 weeks be‐fore suffering from disease (OR=13 .79 ,P=0 .03) and digestive system basic disease(OR=12 .94 ,P=0 .01) .Conclusion Gram‐negative bacterial blood‐stream infection in ICU of the Renmin Hospital of Wuhan University is mainly caused by multi‐drug resist‐ant bacteria .Serum PCT level over 10 .0 ng/mL ,hospitalization duration less than 2 weeks before infection ,receiving the therapy of carbapenem and third generation cephalosporin and basic diseases of digestive system are the independent risk factors influencing the occurrence and diagnosis of blood‐stream infection .

Objective To observe the effects of selfmade Lifeihuayu decotion in the treatment of patients with bronchial asthma.Methods 102 patients with bronchial asthma were randomly divided into the observation group and the control group,each group had 51 cases.The patients in the control group were treated with the conven-tional treatment,while the patients in the observation group were treated with the conventional treatment plus selfmade Lifeihuayu decotion.They were treated for 8 weeks.The patients of the two groups were determined with lung function and blood gas analysis, including forced expiratory volume in one second ( FEV1 ) , forced inspiratory vital capacity ( FVC) ,peak expiratory flow( PEF) ,pH value,the partial pressure of oxygen( PaO2 ) and carbon dioxide partial pres-sure(PaCO2).Results The total effective rate were 98.0% in the observation group and 90.2% in the control group,the total efficiency of the observation group was significantly higher(χ2 =5.78,P<0.05).After treatment,the FEV1,FVC and PEF of the patient's in the two groups were significantly increased(t=5.325,4.821,2.761,all P<0.05),and compared with the control group,the FEV1,FVC and PEF of patients in the observation group improved more significantly(t=2.068,2.771,3.013,all P<0.05).After treatment,the PaO2 of the patient's in the two groups were significantly higher,which more obviously increased in the observation group than those in the control group( t=2.925,P<0.05).After treatment,the PaCO2 of the patient's in the two groups were significantly decreased,PaCO2 in the observation group significantly decreased more than that in the control group(t=3.063,P<0.05).Conclusion Selfmade Lifeihuayu decotion in the treatment of patients with bronchial asthma has curative effect,and can signifi-cantly improve lung function and blood gas analysis of patients.

Objective To determine the effect of age,body figure and risk framing in making treatment decision for female patients with breast cancer.Methods Two groups of healthy female:one group of 60 female ages 18-24 from undergraduate student and the other group of 60 female ages 35-60 from the university community.Healthy women imagined that they had been diagnosed with breast cancer and received information regarding lumpectomy versus mastectomy and recurrence rates.Participants indicated whether they would choose lumpectomy or mastectomy and reasons.Results The different concern levels of body appearance between younger and older women influences treatment selection of lumpectomy versus mastectomy.Facing the risk information,older women were unlikely to select the breast conserving operation.Conclusions The factors of age and the attention to body figure would effect the choice of breast conserving operation or mastectomy.Risk information on the selection of treatment would not affected directly,but the effects of risk information on younger and older female is different.Nurses should provide the age-appropriate information who recently have been diagnosed with breast cancer regarding treatment alternatives to ensure their active participation in the decision-making process,female who have different levels of investment in body figure also may have different concerns about treatment,and should be alert on empathetic of such concerns.

Objective To study influences of magnetic field on behavior of depressive rats under chronic unpredictable mild stress,and possible mechanisms under such phenomena.Methods Thirty-six Wistar rats were divided into model group,magnetic field group and control group (n =12 in each group) according to random number table.The model group and the magnetic field group received CUMS stimulation daily for 5 weeks,while the control group received no any treatment.At the end of the fifth week,rats in the magnetic field group were placed in the center of a magnetic machine (400 mT),and the model group was raised freely for4 weeks.The severity of depressive behaviors,cortisol levels and contents of C-reactive protein in blood and urine sample were tested pre-treatment,at the end of 5 weeks and 9 weeks.Results After 5 weeks,consumption of glucose solution of the control group was higher than the other two groups (P ＜ 0.05).After 5 and 9 weeks,body weights of the magnetic group and the model group were lower than the control group (P ＜ 0.05).At the end of 9 weeks,performance of the magnetic group as indicated by frequency of grid crossing,grooming time and suspending tail test were improved to a significantly greater extent than the other two groups (P ＜ 0.05).In addition,the urine content of cortisol in 24 hours in magnetic field and model groups was higher than the control group at the end of 5 weeks,and the serum level of cortisol in the magnetic field group were significantly higher than the model group at the end of 9 weeks (P ＜ 0.05).Conclusion The 400mT magnetic field can reduce the severity of behavior changes of rats with CUMS-induced depression,which might be attributable to its influence on the cortisol levels in blood and urine.
