Objective:To develop employer's satisfaction evaluation index system towards post competency of residents.Methods:Using Delphi method, the employer's satisfaction evaluation index system towards post competency of residents was formulated through a two-round expert consultation among 19 experts. SPSS 20.0 was used for statistical analysis to calculate the positive coefficient, authority coefficient and coordination degree of experts.Results:For the two rounds of the expert consultation, the questionnaire recovery rate was 95.0% and 100% respectively. The experts' authority coefficient was 0.92, and the system was ultimately determined, including 5 first-level indicators, and 32 secondary indicators. The coefficient of variation (CV) of first-level indicators was 0.00, and the Kendall's W of secondary indicators was 0.663. Conclusions:Employer's satisfaction evaluation index system towards post competency of residents is scientific and reliable, which could provide employer with systematic and objective tool to evaluate residents' post competency.

Objective: To investigate the relationship between breakfast eating frequency and health-risk behavior of high school students in Chongqing, and provide a reference for conducting students to get a good habit of eating breakfast everyday. Methods: A total of 3 283 high school students in Chongqing were selected to participate in a questionnarie by using convenience sampling method. Logistic regression analysis were condueted to analyze the influences made by the unhealty eating behaviors on eating frequency of breakfast. Results: There were 2 064(69.2%) students eating breakfast everyday, 1 219(37.1%) students having no breakfast or eating breakfast sometimes. There were significant differences between different gender, grade, native place, drinking energy drink, smoking, drinking alcohol, gambling, internet addiction students rate of unhealthy breakfast eating frequency(χ2=6.80, 53.97, 8.10, 23.79, 7.89, 16.31, 3.93, 17.96, P<0.05), the males (36.1%) was beyond the females(33.3%), the energy drink drinkers(41.2%) was beyond the non-drinkers(31.7%), the smokers (40.9%) was beyond the non-smokers(34.4%), the alcohol drinkers(40.3%) was beyond the non-drinkers(33.3%), the gamblers(39.7%) was beyond the non-gamblers(34.3%), those having internet addictions (40.0%) was beyond those having no addictions(33.0%). Drinking energy drink(OR=1.32, 95%CI=1.12-1.55), drinking alcohol(OR=1.24, 95%CI=1.02-1.51), internet addiction(OR=1.42, 95%CI=1.19-1.68) were positively correlated with unhealthy breakfast eating frequency of high school students(P<0.05). Conclusion Social, families and schools should strengthen the guidance of high school students to develop the habit of eating breakfast every day, and advoid the clustering of skipping breakfast and health-risk behaviors.

Objective:To evaluate the effect of airway driving pressure (ΔP) guided sedation strategy on the prognosis of patients with mechanical ventilation.Methods:Patients who needed invasive mechanical ventilation and admitted to the department of intensive care unit (ICU) of Jiangxi Provincial People's Hospital from January 2017 to December 2018 were enrolled. The patients were divided into study group and control group according to the random number table. After informed consent of patients or their families, both groups received routine treatment in ICU. The control group was treated with light sedation strategy, the Richmond agitation sedation score (RASS) was performed every 4 hours, and the target was RASS > -3. ΔP in the study group was measured once a day, and the sedative target of patients with low driving pressure (ΔP ≤ 14 cmH 2O, 1 cmH 2O = 0.098 kPa) was RASS > -3, while the patients with high driving pressure (ΔP > 14 cmH 2O) was RASS ≤ -3. The evaluation was conducted at 28 days after admission to ICU, and the patients were followed up to 60 days. The main outcome was days without mechanical ventilation in 28 days. The secondary outcomes were the rate of extubation, discharge outcome, incidence of ventilator associated pneumonia (VAP) and delirium, and 60-day survival rate. Results:A total of 60 patients with respiratory failure due to various reasons were recruited, 30 in each group. There was no significant difference in gender, age, primary disease, severity of disease or ΔP between the two groups. The days without mechanical ventilation within 28 days in the study group were significantly more than that in the control group [days: 20 (0, 23) vs. 12 (0, 16), P = 0.018], and the incidences of VAP (3.3% vs. 16.7%, P = 0.045) and delirium (0% vs. 10.0%, P = 0.038) were significantly lower than that in the control group. There were no significant differences in the rate of extubation (73.3% vs. 66.7%, P = 0.273), discharge outcome [improvement (cases): 24 vs. 21, unhealed (cases): 2 vs. 5, deaths (cases): 4 vs. 4, P = 0.506] and 60-day survival rate (83.3% vs. 76.7%, P = 0.519) between the study group and control group. Conclusion:Compared with light sedation strategy, ΔP directed sedation strategy can effectively shorten the duration of mechanical ventilation and reduce the incidence of VAP and delirium in the ICU patients.

To establish a two-dimensional gel electrophoresis (2-DE) map for comparative proteomic analysis of rat spinal cord with chronic morphine tolerance, and to detect differentially expression proteins that are associated with chronic morphine tolerance.
 Methods: Sixteen male SD rats received the intrathecal catheterization operation and they were randomly divided into a morphine tolerance group (MT group, n=8) and a saline group (NS group, n=8). The lumbar enlargement segments of the MT group and the NS group spinal cord were harvested and proteins were separated by 2-DE. Differential proteome profiles were established and analyzed by means of immobilized pH gradient-based two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). The 2-DE maps were visualized after coomassie blue staining and analyzed using PDQuest analysis software. Identification of differential protein spots was conducted by MALDI-TOF-MS, and the Mascot query software was used to search Swiss-Prot database for bioinformatics analysis. Western blotting was used to verify the expression of some differentially expressed proteins.
 Results: A total of 1 000 spots were identified in 2-DE maps of rat spinal cord tissues from the MT group and the NS group, and 36 proteins were significantly differentially expressed in the MT group compared with the NS group. Identification was conducted by MALDI-TOF-MS and Swiss-Prot database through Mascot query software, and a total of 14 proteins were obtained. Among them, 2 protein spots were down-regulated in the MT group compared with that in the NS group, and 12 protein spots were up-regulated in the MT group compared with that in the NS group. Two kinds of proteins (NUDAA, ENOG) were verified by Western blotting and the results were consistent with proteomics data.
 Conclusion: The optimized 2-DE profiles for the proteome of spinal cord tissue in rats with chronic morphine tolerance is established preliminarily, which showed that morphine tolerance can cause changes in the expression of various proteins in the spinal cord.

Objective To explore the correlation between the dose measured in the rectum and reference dose in three?dimensional brachytherapy ( 3DBT ) for cervical cancer, and to evaluate the significance of the dose measured in the rectum. Methods Fifty patients receiving radiotherapy for cervical cancer were selected, and 3DBT was performed after pelvic external beam radiotherapy. According to the rectal monitoring method recommended in the report ICRU38, in vivo monitoring was applied to obtain the dose measured in the rectum, reference point dose ( DICRU ) , and D2 cm3 , and the planned dose was obtained from the planning system. The differences in these values were determined by the paired t?test and correlation analysis was performed with Pearson test. Results The dose measured in the rectum was higher than the planned dose (3. 48 vs. 3. 25,P=0. 000), and lower than DICRU(3. 48 vs. 3. 71,P=0. 000) and D2 cm3(3. 48 vs. 3. 87,P=0. 002). A linear relationship existed between the dose measured in the rectum and the planned dose, with a deviation percentage of-20% to 40% and an average deviation of 8. 16%;63%of the patients with cervical cancer had a deviation of<± 10%;the maximum deviation was 60%. The dose measured in the rectum had a strong correlation with DICRU(r=0. 722), but a weak correlation with D2 cm3 ( r=0. 284) . Conclusions During 3DBT for cervical cancer, the dose measured in the rectum has certain deviations, but has a linear correlation with the planned dose. Both the dose measured and the planned dose underestimate the dose at the reference point in the rectum, and in vivo rectal monitoring may be an effective method for quality control.

Allotransplantation of peripheral blood-derived hemopoietic stem cells is the best therapy for acute leukemia. With increases of only-child families, sibling donors are decreasing. Moreover, the probability is low and time consuming is long to search a matched hemopoietic stem cell donor from the Chinese Marrow Donor Program. Haploidentical stem cell transplantation would bring a hope for donor resource. However, difficult transplantation and high incidence of graft versus host disease are two risks. Based on modified regimen and cyclosporine A+short-term amethopterin, mycophenolic acid, interleukin-11, anti-lymphocyte immunoglobulin and hemopoietic stem cells mobilized by recombinant human granulocyte colony-stimulating factor can prevent graft versus host disease. This therapy succeeded in two cases with no severe graft versus host disease.

OBJECTIVE:To study curative effect of the combination of cyclosporine A,mycophenolate mofetil,anti-thymocyte globulin,interleukin-11 and short-term methotrexate as acute graft-versus-host disease(aGVHD) prophylaxis on HLA-matched unrelated donor or HLA-mismatched related donor allogenic peripheral blood stem cell transplantation(Allo-PBSCT).METHODS:Thirteen patients with haematological malignancies who underwent HLA-matched unrelated donor or HLA-mismatched related donor Allo-PBSCT with the combination of cyclosporine A as aGVHD prophylaxis at Haikou Municipal People's Hospital from September to November 2008 were selected,including 7 of unrelated donor,3 of haplotype transplantation,and 3 of 1-locus mismatched.The conditioning regimen was performed at 7 days prior to transplantation,with cyclosporine A 5-10 mg/(kg?d),12 hours per time with twice per day.From day 7 prior to transplantation,mycophenolic acid was intravenous drip once per day,then 2.5 mg/(kg?d) antithymocyte globulin at days 5-2 prior to transplantation,1.5 mg/d interleukin 11 was subcutaneous injected at day 2 prior to and 10 days after transplantation,followed by intravenous drip 15 mg/m2 amethopterin at day 1 and 10 mg/m2 at days 3,6,11 after transplantation.The drug doge was reduced and stopped gradually after 3-6 months,which could be prolonged for haplotype grafter.Recombinant human granulocyte colony-stimulating factor was injected subcutaneously at day 3 prior to transplantation,and PBSCT was collected at days 4 and 5 after medication,which was infused to patients with subclavian vein at the same day.In total(7.82-9.11)?108/kg mononuclearcell and(2.9-7.7)?106/kg CD34+ cells were infused.RESULTS:Hematopoiesis was rebuilt in all patients with 46.15%(6/13) aGVHD incidence rate,including 8 %(1/13) of Ⅲ-Ⅳ aGVHD.Up to April of 2009,all patients live and work as normal except one patient who can not visit public places.CONCLUSION:The combination of cyclosporine A,mycophenolate mofetil,anti-thymocyte globulin,interleukin-11 and short-term methotrexate is effective in the prevention of aGVHD.
