Objective To investigate the relationship between the anti-earthquake military rescuers' psychosomatic health and social support, and observe the effect of intervention to the army men who suffered troubles.Methods By cluster random sampling, 152 military rescuers and 139 army men not taking part in the rescues were investigated by Facility Psychosomatic Health Scale and Social Support Rating Scale. Mental intervention or medication was performed to those produced psychosomatic health. Results The scores of somatic symptoms,mental status,psychosomatic health and social support of military rescuers and the control group were (4.09±4.70) ,(2.18 ±3.16) ,(6.27 ±7.08) ,(6.14 ±4.20) and (2.11 ±4.16) ,(1.37 ±3.09),(3.47 ±6.55),(4.57 ± 4.17 )respectively, the difference was significant(P＜0.05). The somatic symptoms had significantly positive correlation with mental status in military rescuers (r=0.17～0.52, P＜ 0.05 or 0.01 ). Failure of social support had positive correlation with mental disorders (r=0.18～0.40, P＜0.05 or 0.01). The degree of social support was the main factor which had affected on the psychosomatic health of military rescuers. The somatic symptoms of military rescuers were apparently higher than their mental symptoms. Mental and pharmaceutical intervention showed good effect on them. Conclusion There is an apparent effect for military rescuers injured seriously psychosomatic health through medication or mental intervention.

Objective To identify distinct subgroups of military personnel from Paracel Islands based on mental status for providing basis to intervention measures.Methods 174 enlisted military personnel were interviewed by symptom checklist-90 (SCL-90).The factor scores of SCL-90 were compared with army man norm and control group,then the cluster analysis was conducted.Results Interpersonal sensitivity,phobic and psychoticism of military personnel on Paracel Islands((1.65±0.56),(1.24±0.33),(1.44±0.46)) scored lower than those of army man norm (P＜0.05).Interpersonal sensitivity of military personnel on Paracel Islands scored lower than those of control (P＜0.05),depression and anxiety of them had no difference to control (P＞0.05),while other factors of them scored higher than control.According to cluster analysis,174 military personnel were divided into three subgroups.The first subgroup with high scores for all nine SCL-90-R dimensions,the second cluster showed moderate scores and the third cluster had lowest scores.Statistically significant sociodemographic differences could be found between the cluster groups (P＜0.05).Conclusion The mental health status of military personnel stationed in Paracel Islands is good on the whole,and can be divided into three clusters with different demographic and service characteristics.

Objective To investigate the possible role of plasma leptin and total cholesterol in the pathophysiology of attempted suicide in depressive episode patients. Methods The subjects were 25 depressive episode patients who had recently attempted suicide and 30 depressive episode patients without suicide attempt. The Hamilton Depression Rating Scale-24 items ( HAMD24 ), Beck Helpless Rating Scale (BHS) and Self-rating Idea of Suicide Scale (SIOSS) were used to evaluate the severity of symptoms. In addition, 32 individuals who took part in health examination were selected as health control group. Body height and weight were measured to get body mass index (BMI) of all objects, and plasma leptin and total cholesterol were measured by venous blood before taking pill. Results (1)HAMD score , BHS score and SIOSS score in patients with attempted suicide were higher than patients without suicide (P ＜ 0.01 ). (2) The total cholesterol and plasma leptin in patients with attempted suicide ( (3.3 ±0.9)mmol/L, (6.1 ±3.7)μg/L)were lower than that in patients without suicide( (3.6± 1.2)mmol/L, (9.4 ± 4.4)μg/L; P ＜ 0.05 ～ 0. 0l ), while total cholesterol and leptin in patients without suicide attempt ( (3.6 ± 1.2 ) mmol/L, ( 9.4 ± 4.4 ) μg/L) were lower than that in normal controls ( ( 4.8 ± 0.9 )mmol/L, ( 13.4 ± 6.7 ) μg/L; P ＜ 0.05 ～ 0.01 ). (3) Plasma leptin and total cholesterol of all patients were positively correlated with BMI(P＜0.01 ). Moreover, plasma leptin and total cholesterol in patients with attempted suicide and patients without attempted suicide were inversely positively correlated with HAMD score , BHS score and SIOSS score. Plasma leptin was significantly positively correlated with total cholesterol in patients with attempted suicide and patients without suicide, but there was no significant difference in normal controls(P＞ 0. 05). Conclusion The results suggest that decreased plasma leptin is related to the pathophysiology of attempted suicide in depressive episode patients.
