心理健康监测是对个体心理健康水平进行周期性的科学评估。开展中小学生心理健康监测,是完善义务教育质量监测的必然要求,是推动素质教育、促进儿童青少年健康发展的重要手段,也是实现健康中国行动的重要保障。我国虽然制定了中小学生心理健康相关的规划与政策,但却尚未建立系统的中小学生心理健康监测体系。对此,本研究在梳理过往理论和实证研究、总结国际先进心理健康调查项目的基础上,提出心理健康监测框架的构建应站位于医学和教育相结合、国际经验和本土化相结合的视角。在此基础上,本研究形成了包含中小学生心理健康状况和影响因素两大部分的、具有中国特色的中小学生心理健康监测框架,对未来我国心理健康监测工作的实际开展提供了思路和指导。

作者： Jinmou Gao dingyuan Du Hui Li Chaopu Liu Shaoyong Liang Qiang Xiao Shanhong Zhao Jun Yang Xi Lin Department of Troumatology Chongqing Emergency Medical Center Chongqing 400014 China

Purpose： Traumatic diaphragmatic rupture （TDR） needs early diagnosis and operation. However, the early diagnosis is usually difficult, especially in the patients without diaphragmatic hernia. The objective of this study was to explore the early diagnosis and treatment of TDR. Methods： Data of 256 patients with TDR treated in our department between 1994 and 2013 were analyzed retrospectively regarding to the diagnostic methods, percentage of preoperative judgment, incidence of diaphragmatic hernia, surgical procedures and outcome, etc. Two groups were set up ac- cording to the mechanism of injury （blunt or penetrating）. Results： Of 256 patients with a mean age of 32.4 years （9-84）, 218 were male. The average ISS was 26.9 （13-66）; and shock rate was 62.9%. There were 104 blunt injuries and 152 penetrating injuries. Preoperatively diagnostic rate was 90.4% in blunt injuries and 80.3% in penetrating, respectively, P 〈 0.05. The incidence of diaphragmatic hernia was 94.2Z in blunt and 15.1% in penetrating respectively, P 〈 0.005. Thoracotomy was performed in 62 cases, laparotomy in 153, thoracotomy plus laparotomy in 29, and combined thoraco-laparotomy in 12. Overall mortality rate was 12.5% with the average ISS of 41.8; and it was 21.2% in blunt injuries and 6.6% in penetrating, respectively, P 〈 0.005. The main causes of death were hemorrhage and sepsis. Conclusions： Diagnosis of blunt TDR can be easily obtained by radiograph or helical CT scan signs of diaphragmatic hernia. For penetrating TDR without hernia, ＂offside sign＂ is helpful as initial assessment. CT scan with coronal/sagittal reconstruction is an accurate technique for diagnosis. All TDR require operation. Penetrating injury has a relatively better prognosis.

Background： To evaluate the short-term and long-term outcomes after laparoscopic hysterectomy （LH） compared with abdominal hysterectomy （AH） in case of benign gynecological disease. Methods： A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies （3,539 LH vs.1,356 AH） between 2007 and 2013 was involved. Operative time （OT）, estimated blood loss （EBL）, intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed. Results： The EBL （174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively）, passing flatus （38.7±14.1 vs. 48.1±13.2 hours）, days with indwelling catheter （1.5±0.6 vs. 2.2±0.8 days）, use of analgesics （6.5% vs. 73.1%）, intra-operative complication rate （2.4% vs. 4.1%）, post-operative complication rate （2.3 % vs. 5.7%）, post-operative constipation （12.1% vs. 24.6%）, mild and serious stress urinary incontinence （SUI） post-operative （P〈0.001; P=0.014）, and proportion of Female Sexual Functioning Index （FSFI） total score 〈26.55 post-operative （P〈0.001） of the LH group were significantly less than those of AH group. There were no significant differences in OT （106.5±34.5 vs. 106.2±40.3 min） between the two groups. Conclusions： LH is a safe and efficient operation for improving patients＇ long-term quality of life （QoL）, and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus.

In the 21st century, natural disasters and emergencies occur frequently worldwide, which leads to the loss of hundreds of thousands of lives as well as the direct and indirect economic losses. China has a vast territory frequently struck by natural disasters. However, the reality is not optimistic. Poor organization and management during the rescue actions, the lack of large-scale, systematic medical rescue equipment were all great barriers to the outcomes. Mobile hospitals are expected to provide better health care. We were inspired by the concept of mobile hospital. Chongqing Emergency Medical Center, has set up trauma care system since 1988, in which pre- hospital care, intensive care, and in-hospital treatment is fully integrated. As a major advantage, such a system provided assurance of＂golden hour＂ rescue treatment. Providing mobile intensive care and pre- hospital surgical service for severe trauma patients could reduce mortality significantly. Based on the civilian experiences in Chongqing Emergency Medical Center, the mobile emergency （surgical） hospital was developed. 2015 Production and hosting by Elsevier B.V. on behalf of Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.
