Intervention effect of health education combined with aerobic exercise on adolescent depression / 中国学校卫生

Objective@#To explore the intervention effect of health education combined with aerobic exercise on adolescent depression,and to provide a reference for depression prevention of adolescents.@*Methods@#A total of 84 adolescent patients with depression in Wuhan Mental Health Center were selected by convenient sampling method. They were divided into two groups according to the order of patients visits (n=42). The control group received routine health education. The experimental group received group health education of emotional intelligence, and cooperated with moderate intensity aerobic exercise. The changes of depression, emotional intelligence and serotonin (5-HT), cortisol and norepinephrine (NE) levels before and after intervention were compared between the two groups.@*Results@#Before intervention, there was no significant difference in scores of Hamilton Depression Scale (HAMD) and Social Disability Screening Schedule (SDSS) between the two groups (t=0.62，1.02，P>0.05). The scores of HAMD and SDSS in the experimental group were significantly lower than those before intervention (t=9.62, 10.05, P<0.05). The scores of HAMD and SDSS in the experimental group were significantly lower than those in the control group (t=-6.95，-7.32，P<0.05). The scores and total scores of emotional perception, self-management and other management in the experimental group after intervention were significantly higher than those before intervention (t=6.54, 7.21, 5.33 ，6.60, P<0.05). The scores of emotion perception, self-management, others’ management and total scores in the experimental group were significantly higher than those in the control group(P<0.05). compared with before intervention, the levels of 5-HT and NE in the experimental group after intervention were significantly higher, the levels of cortisol were significantly lower (t=4.62, 5.36，-16.54, P<0.05)，and the level of 5-HT and NE in the experimental group was significantly higher than that in the control group, and the level of cortisol was significantly lower than that in the control group (t=15.25，8.74，-26.54，P<0.05).@*Conclusion@#The implementation of emotional intelligence group health education and aerobic exercise can effectively reduce the level of 5-HT, improve the level of cortisol, enhance the emotional intelligence of adolescents with depression, and alleviate their depressive mood.

[Identification of Anaplasma phagocytophilum in small mammals from Hengduan Mountains of Southwest China].

OBJECTIVE: To investigate the prevalence of Anaplasma phagocytophilum in small mammals from the forest area of Hengduan Mountains in southwestern China. METHODS: Small mammals captured from Gaoligong and Xianggelila mountainous area of Yunnan province were detected by PCR amplification. The sequences of 16S rRNA and Msp4 gene fragments from positive samples were compared with corresponding sequences deposited in GenBank. RESULTS: A total number of 436 small animals, which belongs to 5 orders 18 genera 35 species were tested, 32 (7.34%) were positive in 6 genera 11 species. There were 8.64% (26/301) positive in 25 species at Goligong mountainous areas, and 4.44% (6/135) were positive in 19 species at the Xianggelila mountainous areas. Positive small mammals were most rodents. The nucleotide sequences of A.phagocytophilum 16S rRNA gene amplified from small mammals varied from 99% - 100% and were 99% - 100% similar with the corresponding segments of A. phagocytophilum from Jilin deposited in GeneBank. The sequences of A. phagocytophilum Msp4 gene showed that there was 95% - 97% similarity with the corresponding sequences registered in GenBank. CONCLUSION: A. phagocytophilum was firstly identified in 6 genera 11 species small mammals from a forest area of Hengduan Mountainous areas in southwestern China. Rodents might serve as the primary hosts indicating the potential risk to the domestic animals and human beings in this area.

[Application and results of Robicsek procedure for dilated ascending aorta associated with aortic valve disease].

OBJECTIVE: To introduce the Robicsek procedure and summarize its short to mid-term results for patients with dilatation of the ascending aorta associated with aortic valve disease. METHODS: From December 2002 to June 2006, 30 patients with a moderately dilated ascending aorta [mean diameter, (46.7+/-3.1) mm] underwent concomitant aortic valve replacement (AVR) or repairing and reinforced aortoplasty with a well-tailored Dacron vascular graft. Follow-up was obtained on all patients with ultrasonic cardiography (UCG) or computed tomography (CT) scan and was (18.0+/-10.5) months. RESULTS: The total average cardio-pulmonary bypass (CPB) time was (103.4+/-21.7) min (80-151 min), and aortic arrest time was (73.0+/-21.6) min (48-120 min), whereas the average CPB time and aortic arrest time of 19 patients who underwent the isolated Robicsek procedure were only (91.3+/-8.9) min (80-118 min) and (61.6+/-11.3) min (48-82 min). No mortality occurred in the hospital. During follow-up of 18 months, no recurrent ascending aortic dilatation and dissection were observed, and the average aortic diameter was reduced to (33.7+/-2.5) mm. Sixteen of the 30 patients were diagnosed as bicuspid aortic valve (BAV). The ascending aortic media were histologically abnormal in 23 patients. CONCLUSION: Considering the underlying wall deficiency and the homodynamic stress, the Robicsek operation should be an optimal choice to those patients with a mild to moderate dilated ascending aorta caused by aortic valve lesion. Compared with the Bentall and David procedures, the Robicsek procedure could achieve the same or even better clinical results with less operative time and risks.
