Objective To test the reliability and validity of the collective self-esteem scale for freshman.Methods 800 freshmen finished the Collective Self-Esteem Scale,the Life Satisfaction Scale,and Self-esteem Scale.Results The confirmatory factor analysis shows that collective esteem includes membership esteem,private collective esteem,public collective esteem,and importance to identiy intemal consistency a of the scale and the 4 components of the scale ale between0.6357and 0.8369.All components of the scale except importance to identity have significantly positive correlation with life satisfaction and self-esteem.(0.14＜r＜0.41,P＜0.01).Gids have more scores than boys in total collective esteem(t=3.38,P＜0.01),Private CSE and Importance to Identity (t=3.32,P＜0.01).Conclusion The revised collective self-esteem scale for freshmen has sound reliability and validity.It is a good instrument for measuring collective self-esteem of Chinese freshman.

Objective To investigate the status of undergraduate nursing faculty's structural empowerment and job satisfaction and to analyze the correlation between themn.Methods Totally 246 nursing teachers were investigated with Conditions for Work Effectiveness Questionnaire Ⅱ and Minnesota Satisfaction Questionnaire.The correlation between structural empowerment and job satisfaction were analyzed by Pearson correlation analysis.Results Undergraduate nursing faculty's total score was (3.04±0.57) points,and score of job satisfaction was (2.93±0.59) points,both of which were at moderate level.Structural empowerment was positively correlated with job satisfaction (r=0.450-0.714,P＜0.01),the higher structural empowerment level,the higher job satisfaction.Conclusions Undergraduate nursing managers can improve nursing teachers' job satisfaction by strengthening the empowerment to nursing teachers,in order to enhance the teaching quality.

Methods Delphi method was applied to this research. All questionnaires were designed based on the literature research and distributed to more than 30 experts for 3 rounds. And the results in the first two rounds of survey were analyzed. Results Totally 31 and 33 valid questionnaires were received in the first and second time respectively. The experts’ activity index was 88.6% and 93.4% respectively. The perfume pouch wearing methods of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy was set down. And most of the experts shared a positive view on the concentration and coordination degree of this book. Conclusion The experts’ opinions upon this draft are quite positive. The experts are from all over China, and they are quite professional, with representativeness. The perfume pouch wearing methods of Practice Guidelines to Prevent Disease for Recurrent Respiratory Tract Infections in Children Prevented by Sachet-Therapy are generally recognized by the experts. However, there are still some different ideas in terms of some indexes, which need to be further discussed.

Objective To explore the relationship between peritoneal lavage cytology in gastric carcinoma and lymph node metastasis.Methods From June 2012 to May 2014,intraoperative peritoneal lavage for cancer cells was carried out in 226 gastric cancer patients undergoing gastrectomy.During the process 63 patients were irrigated with 500 ml of normal saline,while the others were using 1 000 ml.D2+ lymph nodes dissection was performed to evaluate the relationship between peritoneal lavage cytology in gastric carcinoma and lymph nodes metastasis.Results The positive rates of exfoliative carcinoma cells were 11.1％ in the 500 ml group and 9.2％ in the 1 000 ml group (x2 =0.188,P=0.695).In both groups,rate of exforliative cancer cells were positively related to lymph node metastasis,the numbers of positive lymph nodes,the station of lymph nodes metastasis,the rate of the lymph nodes metastasis and that of the second station (all P ＜ 0.05),but not to the numbers of the lymph node cleaned (P ＞ 0.05).Conclusions Lymph nodes metastasis was an important risk factor that contribute to exfoliated carcinoma cells in patients with gastric carcinoma,and especially in those with lymph nodes metastasis at the second station.

Objective To investigate the clinicopathological features of primary gastric malignant lymphoma.Methods 32 cases of primary gastric non Hodgkin's malignant lymphoma(NHL)were studied by clinicopathology,immunohistochemistry and ultrastructure.Results 3 cases of NHL arose from fundus of stomach,7 cases from body of stomach,8 cases from gastric angle,and 14 cases from gastric antrum.The paraffin sections of all cases were stained.There were 31 cases(96\^9%)exhibiting B cell phenotype,only 1 case(3\^1%)exhibiting T cell phenotype.11 cases of NHL and 6 cases of undifferentiated carcinoma(UC)in stomach were observed comparatively under electron microscope(EM).The ultrastructural characteristics of NHL were much different from those of UC.Conclusion Most primary gastric malignant lymphoma are B cell lymphomas.Immunohistochemistry and ultrastuctural observation are much helpful in the diagnosis and differential diagnosis between NHL and UC.

Objective To investigate the diagnostic value of breast MRI in patients presenting with microcalcifications on mammography.Methods Eight four patients were retrospectively analyzed,who had mammographically detected BI-RADS (breast imaging reporting and data system) 3 to 5 microcalcifications and underwent breast MRI before surgical biopsy.All mammography and MR images were reviewed with BI-RADS.With histopathological diagnosis as golden standard,the sensitivity,specificity and accuracy of the two methods were calculated and compared with x2 test or Fisher exact test.The diagnostic efficacy of the two methods was compared with ROC curve.Results Pathologic examination revealed 91 lesions in 84 patients including 49 benign lesions and 42 malignant lesions.For 21 lesions of category 3 microcalcifications,the specificity of mammography and MR was 100.0％ (21/21) and 95.2％ (20/21),which had no significant difference (P=1.000).For 51 lesious of category 4,sensitivity,specificity and accuracy of mammography were 100.0％(23/23),0 and 45.1％(23/51).The corresponding values for MR were 91.3％(21/23),82.1％ (23/28) and 86.3％ (44/51).The difference for specificity and accuracy between the two methods was statistical significant(x2 value was 30.030 and 19.182,respectively,with P＜0.01),but not for sensitivity(x2=0.523,P=0.470).Nineteen lesions of category 5 were all correctly diagnosed on mammography and MRI.For all the 91 lesions,the sensitivity,specificity and accuracy of mammography were 100.0％(42/42),42.9％(21/49) and 69.2％(63/91),respectively.The corresponding values for MRI were 95.2 ％(40/42),87.8％(43/49) and 91.2％(83/91).There was significant difference for specificity and accuracy between the two methods (x2 value was 21.798 and 13.851,respectively,with P＜0.05),but not for sensitivity (x2=0.512,P=0.474).The areas under ROC curve for mammography and MR were 0.844,0.945(P＜0.01),for the estimation of the benign and the malignent.Conclusions Compared with mammography,breast MRI significantly improved the diagnosis of category 4 microcalcifications with increased specificity and accuracy.But for microcalcifications of category 3 and 5,MR didn't improve the diagnostic effect.

This study was aimed to explore recognition models and to establish statistical pattern recognition methods of cold-hot property markers based on lipid components GC-MS chromatogram of Chinese materia medica (CMM). GC-MS fingerprints of lipid components contained in 60 kinds of cold or hot property of CMM were used as the research object. The database was established. Five types of model establishment strategies were compared. Optimal modeling patterns were screened for the identification of herbal property markers of lipid components GC-MS chromatogram. The results showed that support vector machine (SVM) was the best model to discriminate cold or hot property among 60 types of CMM, which were able to effectively mark the characteristic area. The strongest markers tending to cold property was at the retention time of 61.550 min, while the strongest markers tending to hot property was at the retention time of 31.395 min. It was concluded that cold or hot property of CMM had close relationship with lipid components. The lipid component was one of the material bases of CMM. The mathematical statistical model based on material base and herbal property can be used to identify and predict the cold and hot property of CMM.
