Objective Through retrospective data analysis,we tried to further understand the epide-miological characteristics,clinical feature and death factors of infant and young children with severe pneumo-nia. Methods The study objects were inpatients( age between≥28 days and≤3 years) who were diagnosed severe pneumonia from 1 January,2011 to 31 December,2013 of the Chengdu Women′s and Children′s Cen-tral Hospital. We used retrospective case study to understand the epidemiology,clinical feature,death factors of infant and young children with severe pneumonia. And we used chi-square test and Logistic multivariate regression analysis to analyze the death factors of infants and young children with severe pneumonia. Results (1) Among 1 411 cases of severe pneumonia,the ratio of male and female was 1. 8∶1,and the ratio of urban and rural areas was 1∶3. 62. The proportion of less than 3 months old infant was 46. 00%. And 62. 93% infant and young children with severe pneumonia occurred in the spring and winter. (2) Average hospitalization time was (9. 99 ± 6. 27 ) days, longer than the hospitalization time of mild pneumonia patients. ( 3 ) A total of 64. 21% of infant and young children with severe pneumonia had basic diseases. (4)A total of 91. 99% of the infant and young children with severe pneumonia had complications. (5) The most common etiology of infant and young children with severe pneumonia was bacteria,the second was virus. (6) In all cases,there were 44 cases died. The mortality of infant and young children with severe pneumonia was 3. 12%. And 72. 73% of the death cases were infants less than 3 months old. (7) The results of Logistic multiple regression analysis showed that there were significant differences in age, congenital heart diseases, repeating infection history, multiple drug-resistant strains infection, surgical history, multiple organ dysfunction, internal environment disorder. Conclusion Infant and young children with severe pneumonia have the following characteristics:most of them occurred in the winter and spring, and come from rural more than from the city. The smaller the age, the incidence of a disease is higher,and the mortality is higher. Most of infant and young children with severe pneu-monia have basic diseases. Most of the infant and young children with severe pneumonia have complications. If having one of the following high-risk factors:less than 3 months old,congenital heart diseases,repeating infec-tion history,multiple drug-resistant strains infection,surgical history,multiple organ dysfunction,internal envi-ronment disorder,the infant with severe pneumonia should be intensively monitored and actively treated.

Objective To analyze the changes of splenic volume and blood flow detected by ultrasonography in men having been migra-ted in high-altitude area for 10 years and to explore the relationship between the splenic blood flow and volume. Methods Men migrating to high-altitude area for 10 years,male indigenous Tibetan and healthy men from planitia with 55 cases in each were involved. Ultrasonography was performed to measure the length,width and thickness of spleen to calculate the volume,and color Doppler flow imaging was applied to measure the diameter of splenic artery and the mean flow velocity to calculate the blood flow volume. The differences among groups were com-pared and the relationship between the blood flow and the volume was analyzed. Results The blood flow and the volume of spleen in men migrating to high-altitude area were higher than those in male indigenous Tibetan and healthy men from planitia (P<0. 01),and the blood flow was positively correlated with the splenic volume (r=0. 828,P<0. 01). Conclusion The splenic volume and blood flow are increased in men when have been migrated in high-altitude area for 10 years and ultrasonography is of great importance in detecting the pathophysiologic changes in high-altitude area in our country.

Objective:To analyze the relationship between each dimension of emotional intelligence and interpersonal communication ability, and explore how to improve the interpersonal communication ability of residents through targeted emotional intelligence training.Methods:A total of 132 first-year residents of clinical medicine in the residency training base were jointly measured with emotional intelligence and interpersonal communication evaluation scale on the basis of self-assessment and grading. The differences between groups in self-assessment and grading were detected by one-way ANOVA, and the relationship between various dimensions of emotional intelligence and interpersonal communication ability was explored by correlation analysis and multiple linear stepwise regression analysis. SPSS 19.0 was used to conduct statistical analysis.Results:The self rating scale clearly divided the subjects into three levels. In the total score of emotional intelligence and its various dimensions, the differences between the three levels were statistically significant; the scores of the "good" group were higher than those of the "fair" group and the "slightly insufficient" group. There were statistical significance in the total score of emotional intelligence ( P<0.001) and its emotional perception ( P<0.001), self emotional management ( P<0.001), others' emotional management ( P<0.001) and emotional utilization ( P<0.001). In the total score of interpersonal communication ability and its various dimensions, the differences among the three levels were statistically significant. In the conflict management, the difference between the "good" group and the "fair" group was not statistically significant, and the differences in other items were statistically significant. The total score of emotional intelligence and its dimensions were positively correlated with interpersonal communication ability ( P<0.001), but the two dimensions that had the most significant impact on interpersonal communication ability were emotional perception and others' emotional management ( R2=0.531, P<0.001). Conclusion:By focusing on the cultivation of each dimensions of emotional perception and other emotional management for residents, it is expected to play a positive role in achieving the national goal of cultivating interpersonal communication skills.
