Objective:To explore a new way of nursing teaching round-making compatible with the nursing students at junior college,and to establish and improve the standards for its assessment.Methods:We performed a new mode of nursing teaching ward round jointly organized by nursing teachers of the school and clinical supervisors of the hospital among student nurses of Grade 2006 on four different subjects respectively,by going through the following four steps: establishing the subject,working out the plan,making the ward round and assessing the quality.Results:The average score on the quality assessment of the four subjects by teachers and students was 93.78.Conclusion:The new mode of nursing teaching ward round jointly organized by the school and hospital can make the best of nursing faculty resources,give full play to nursing students'potential and optimize this activity and facilitate the teaching of clinical nursing.

Objective: To explore an integral training mode for student nurses in large modern general hospitals.Methods: Integral nursing training was conducted in our hospital among 610 student nurses from universities and postsecondary specialized colleges.Results: All the student nurses considered the integral training to be helpful for the promotion of their professional nursing competence.Conclusion: The professional competence-oriented integral nursing training can optimize the teaching quality of clinical nursing and help enhance the professional competence and comprehensive qualities of student nurses.

Objective:To detect the expression of chemokine receptor CCR5 in human invasive ductal breast carcinoma and explore the role of CCR5 in breast cancer.Methods: Thirty samples of invasive ductal breast carcinoma and 10 samples of breast fibroadenoma were analyzed separately by immunohistochemical staining for CCR5 expression. MIP1?,MIP1? and RANTES concentrations were measured by ELISA in the sera of patients. Results: The expression of CCR5 was detected in invasive ductal breast carcinoma (the positive rate was 53.3%) and was not detected in breast fibroadenoma. RANTES concentrations in the serum of breast carcinoma patients increased significantly (P

Objective:Deeper studies have been rarely reported on the characteristics and influencing factors of the psychological health of army nurses and on the measures for raising their ability of military stress management. To gain an insight into the psychological state of army nurses in the present military streamlining and to explore its countermeasures. Methods:We investigated the psychological state of 123 army nurses from 6 military hospitals by psychometrical methods and psychological interviews,and analyzed the results. Results:Of the total number of subjects,70.73% scored

ObjectiveTo study the role of chemokines and their receptors in peripheral blood in the pathogenesis of breast cancer in elderly patients.MethodsSerum levels of regulated on activation normal T-cell expressed and secreted(RANTES),macrophage inflammatory protein-3 α (MIP-3α ) and stromal cell derived factor-1(SDF-1) were determined by double-antibody sandwich enzyme-linked immunosorbent assay(ELISA) in 30 elderly patients with breast cancer(breast cancer group) and 30 normal controls (control group).Meanwhile,chemokine receptors,CC chemokine receptor(CCR)5,CCR6 and CXC chemokine receptor(CXCR) 4 on peripheral blood CD3+ T-cell in two groups were analyzed by flow cytometry.ResultsSerum levels of RANTES,MIP-3 α and SDF-1 in breast cancer group were significantly higher than those in control group [ (27.9 ± 16.6) μ g/L vs.( 12.6 ± 4.2) μ g/L,( 10.9 ± 7.1 ) μ g/L vs.(5.4 ± 3.5 )μg/L,(339.4 ±94.6) ng/L vs. (195.0 ±70.8) ng/L,P ＜0.01].There was no significant difference in expressions of CCR5,CCR6 and CXCR4 on peripheral blood CD3+ T-cell between two groups(P ＞ 0.05).ConclusionThe abnormal increase of serum levels of RANTES,MIP-3 α and SDF-1 in peripheral blood may play role in the carcinogenesis and progress of breast cancer in elderly patients.

Objective To evaluate the clinical value of echocardiography in the diagnosis of aorticoleft ventricular tunnel.Methods The echocardiographic and clinical characteristics were retrospectively analyzed in 6 patients with aortico-left ventricular tunnel we reported and 147 cases that documents reported.Results Six patients were confirmed by operation.The main echocardiographic characteristics of aortico-left ventricular tunnel were as follows:An abnormal communication began in the ascending aorta above the level of the coronary arteries,bypassed the aortic valve,and terminated in the left ventricle.The color Doppler flow imaging demonstrated to-and-fro flow,with or without aortic valve involvement.According Hovaguimian and his colleagues,2 cases were type Ⅰ,2 cases were type Ⅲ,1 case was type Ⅳ,1 case was type Ⅱ (showed as recanalization).Base on all of the 153 patients that we and documents reported,the accuracy rate of ultrasound diagnosis was 79.6％,the misdiagnosis rate was 17.1％,and missed diagnosis rate was 3.3 ％.Conclusions Echocardiography is the non-invasive and sensitive tool in the diagnosis of the type of aortico-left ventricular tunnel and structure of cardiac involvement,and is the preferred method for preoperative.

Objective To investigate the training methods and evaluation parameters for donor lung procurement technique in swine models. Methods The surgical skills of donor lung procurement in 15 swine models were summarized. The operation time, objective evaluation parameters before lung perfusion, gross observation after lung perfusion, the type and frequency of intraoperative errors were assessed. Results All donor lung procurement surgeries were successfully completed in 15 swine models. The mean time interval from skin incision to lung perfusion was 22.6 min. Prior to lung perfusion, the oxygenation index of the donor lung was (501±68) mmHg, (404±100) mL (under the pressure of 15 mmHg) for the tidal volume and (29±4) mL/cmH2O for the static compliance. Along with the increasing surgical frequency, the oxygenation index and tidal volume were improved. Favorable lung inflation was obtained after lung perfusion in a majority of swine models. Intraoperatively, multiple operating errors occurred including dissection error, pulmonary arterial intubation error and procedure error, etc. As the frequency of operation increased, the frequency of surgical errors was significantly decreased. Conclusions After certain training for donor lung procurement in swine models, the incidence of intraoperative procedure error is significantly reduced and the quality of the donor lung tends to be enhanced. Objective parameters, such as oxygenation index and the gross shape of the donor lung can be utilized to evaluate the levels of surgical techniques.

Objective To investigate the effect of limitation in flow of people on medical care quality in emergency resuscitation room (ERR).Methods This study was retrospectively performed to compare emergency medical quality before and after (October to December,2015 vs.February to April,2016) limitation of flow of people in ERR.Variables included noise level,occupational exposure,adverse event,hospital-acquired infection,length of stay (LOS) in ERR,mortality rate,return of spontaneous circulation (ROSC) rate after cardiopulmonary resuscitation (CPR),the rate of unexpected return to ERR,door to drug and door to balloon time for patients with ST-segment elevated myocardial infarction (STEMI),patients' and emergency personnels' satisfaction level.The data were analyzed with t-test,chi-square test or Poisson Z test where appropriate.Results There were 5 031 and 5 097 patients respectively admitted in ERR before and after limitation of flow of people.Patients' main diagnoses and severity of illness between the two periods had no significantly difference (P＞0.05).After the limitation of flow of people,the noise level in ERR was lowered (P＜0.01),the numbers of occupational exposure events (14 cases vs.4 cases,Z=2.357,P=0.018) and adverse events (18 cases vs.5 cases,Z=2.711,P=0.007) were decreased,the rate of hospital-acquired infection was reduced (1.1％ vs.0.5％,x2=8.111,P=0.004),the LOS in ERR was shortened [(6.3±0.8) h vs.(4.6±0.6) h,t=121.083,P＜0.01],the door to balloon time for STEMI patients was also decreased [(91.2±12.8) min vs.(89.3±8.0) min,t=2.486,P=0.013].Moreover,patients' and emergency personnels' satisfaction level were elevated.No significant difference was observed in mortality rate,ROSC rate,rate of unexpected return to ERR and door to drug time for STEMI patients.Conclusions The limitation of flow of people in ERR can lower the noise level,reduce emergency personnels' working pressure,improve their working efficiency,avoid medical errors,elevate patients' and emergency personnels' satisfaction level.
