Objective To understand the operators'psychosomatic health status in nuclear power plant;and provide the scientific basis of measures for preventing and reducing mental disorders in operators.Methods The Psychosomatic Health Battery(PSHB) was used to assess the psychosomatic health status in 109 operators who were random selected from Qinshan nuclear power plant,etc.They were tested from lie,emotional stability,liveliness,tension,apprehension,mental health,such as psychopathic deviatesuch 7 personality traits.Results Lie < 8,all inspected groups were normal.Psychopathic deviate:98.2% for normal group 0.9% for both of groups occurred possible mental health problems and confirmed mental health problems ;Mental health:80.7% (88/109) for fine mental health ones,29.4% (32/109) for those with excellent mental health,51.4% (56/109) for good mental health ones,13.8% (15/109) for general mental health ones,5.5% (6/109) for poor mental health ones.Age factor could influence the mean values of the factors of apprehension,tension,mental health and psychopathic deviate.Correlation analysis showed that there was a correlation between tension and psychopathic deviate(r = 0.664 ,P < 0.01),and the other correlation coefficient was between apprehension and mental health(r =-0.789 ,P < 0.01).Conclusions There is an excellent condition of psychosomatic health in most of the operators,however,there are still a very small percentage of psychosomatic disorders among these operators,to improve the quality of their psychosomatic health,psychological counseling should be particularly strengthened to those with problems of psychosomatic health.

Objective To explore the correlation of the anti-stress ability of nuclear power plant operators with their heart rate,blood pressure and mental health.Methods A total of 136 male nuclear power plant operators received the continuous performance test (CPT) and mental health test (MHT),while 37 male senior students were used as the control group.Heart rate and blood pressure were recorded before and after the test.The nuclear power plant operators were divided to high score group and low score group by CPT scores.The correlation of the anti-stress ability and blood pressure,heart rate and their mental health was analyzedd.Results The scores of CPT and MHT test with the operators were significantly higher than those of the control group(t =- 1.25,6.25,P ＜ 0.05).After the test,the heart rate,systolic pressure and diastolic pressure of the operators were all significantly lower than those of the control group ( t =- 2.07,3.28,2.74,P ＜ 0.05 ).The CPT score of the high score group was lower in the heart rate,systolic pressure and diastolic pressure than the low score group(t=-3.15, -2.78, -2.54,P ＜0.05),while the scores of CPT and MHT were better(t =0.63,6.90,P ＜ 0.05).CPT scores were negatively correlated with the increasing range of the heart rate,systolic pressure and diastolic pressure( r =- 0.69,- 0.94,and - 0.62,P ＜ 0.05 ),and positively correlated with the MHT scores ( r =0.54,P ＜ 0.05 ).Conclusions To a certain extent,CPT and MHT test can reflect the anti-stress ability and be used as one of the bases to select nuclear power plant operators and to assess their competence.

Objective To explore the personality features of nuclear power plant operators and the influencing factors thereof.Methods Minnesota Multiphasic Personality Inventory was used to examine the personality features of 136 nuclear power plant operators randomly selected from 2 cooperative units,all males.The results were compared with the nationwide norms and subsequently an inter-block contrast analysis was carried out.Results Obvious difierence was observed in the final scores between the nuclear power plant operators and nationwide norms.The former got higher scores on hysteria(t=3.05,P<0.05).and lower scores on hypochondriasis,depression,morbid personality,masculinity-femininity,paranoia,psychasthenia,schizophrenia,hypomania,and social introversion(t=7.47,7.47,7.3 1,2.23,15.09,16.15,19.28,7.88,11.10,P<0.05).The scores on hypochondriasis,depression,schizophrenia,and social introversion of those with the length of services over 3 years were all significantly higher than those ofwith the length of services less than 3 years(t=3.25,2.51,2.76,3.00,P<0.05).The scores on hypochondriasis,depression,psychop8thicdeviate,and social introversion of the operators aged over 30 were all significantly higher than those of the operators aged below 30(t=2.36,2.35,2.01,2.54,P<0.05).Conclusions The psychological quality of the nuclear power plant operators is superior to that of the general population.

Objective To explore the status of nuclear power plant operators in mental health and its correlation with emotional stability,liveliness,anxiety and urgency.Methods 255 male operators were randomly selected from three nuclear power bases,meanwhile 61 undergraduates were used as control group.The mental health and neurobehavioral evaluation system of Chinese nuclear power plant operators was developed by Second Affiliated Hospital of Soochow University,which was used to assess mental health of the subjects.The scores of mental health personality factors were recorded,together with four main personality factors including emotional stability,liveliness,anxiety and urgency.Results The score of lie was lower than 8 which showed all inspected groups were normal. 1.57％ (4/255) operators had psychological disorders,3.92％ ( 10/255 ) had poor mental health,27.84％ ( 71/255 ) had general mental health,66.7％ (170/255) had excellent mental health,whereas 9.84％ (6/61)for control group had psychological disorders.Obvious difference was observed in the final scores between the nuclear power plant operators and control group.The former gained higher scores on mental health,emotional stability,and lower scores on anxiety and urgency ( t =3.437,4.423,- 2.493,- 2.093,P ＜ 0.05 ).Both groups aged over 27 years and with length of service over 5 years were awarded higher scores on mental health,emotional stability( t =2.585,2.349 ; t =2.606,2.947,P ＜ 0.05 ),lower scores on anxiety and urgency (t =- 3.407,- 2.138 ; t =- 2.941,- 2.256,P ＜ 0.05).The mental health was positively correlated with emotional stability and liveliness ( r =0.721,0.650,P ＜ 0.05),but negatively correlated with anxiety and urgency(r =- 0.809,- 0.693,P ＜ 0.05 ).Conclusions The majority of nuclear power plant operators had excellent psychological quality,but some factors should be paid more attention,such as different ages and length of service time.

The purpose of this study is to suggest the physicians using olanzapine to strengthen the recognition and treatment of restless leg syndrome （RLS） in clinical practice. In this paper， one patient with schizophrenia suffered from RLS during olanzapine administration， which was characterized by unpleasant sensory disturbances in bilateral lower extremity at night， intense urges to move legs， and inability to sleep. After taking gabapentin， the above symptoms were significantly improved.
