Association of drinking behavior and self injury behavior in adolescents / 中国学校卫生

Objective@#To explore the association between drinking behavior and self injury behavior in adolescents.@*Methods@#A total of 9 247 students from 4 middle schools were investigated. Drinking behavior and self injury behavior were collected from questionnaire survey. Univariate and multivariate Logistic regression analysis were used to analyze the relationship between drinking behavior and self injury behavior.@*Results@#Among the 9 247 middle school students, 52.8% reported ever drinking, 24.9% reported drinking behavior in the past 30 days, and 14.6% reported been drunk in the past year. The average age of drinking for the first time was 12.47±3.05. About 47.2% of the participants had self injury behavior. Male with younger drinking age ( OR =1.52), had been drunken ( OR =1.35) and frequent drinking ( OR =1.54) increased the incidence of self injury. Female reported drinking at younger age ( OR =1.69), had been drunk ( OR =1.82) and lived in cities and towns ( OR =1.20) had a higher risk of self injury.@*Conclusion@#Drinking at younger age, heavy and frequent drinking are associated with higher risk of self injury in adolescents in sex specific fashion.

The operative technique selection of lung transplantation for end-stage emphysema / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the operation of lung transplantation for end-stage emphysema.</p><p><b>METHODS</b>From September 2002 to February 2005, 9 patients with chronic obstructive pulmonary disease (COPD) underwent lung transplantation. The types of surgery included single lung transplantation in 2 patients, lung transplantation with asynchronous contralateral lung volume reduction (one week later) in 1, single lung transplantation with synchronized contralateral lung volume reduction in 4, and bilateral sequential lung transplantation without cardiopulmonary bypass in 2.</p><p><b>RESULTS</b>The volume of chest drainage was more than 2000 ml at the first postoperative day in 2 patients, one was reoperated for hemostasis and another was successfully responded to conservative therapy. The ventilation time was ranged from 3 to 22 days postoperatively. Two patients were received tracheotomy. Seven patients achieved good results, two of them had returned to work, and 1 patient had lived for 30 months. One patient was died of severe acute rejection (4A) at 15th postoperative day and 1 succumbed to multisystem organ failure due to severe bacterial infection combine fungal infection.</p><p><b>CONCLUSION</b>End-stage emphysema is an indication for single lung transplantation. Single lung transplantation with contralateral lung volume reduction is a good way to utilize donor. If patient suffered from infection, double-lung transplantation should be considered first.</p>
