ABSTRACT

Objective To investigate the difference of Alzheimer-associated neuronal thread protein ( AD7c-NTP) level and related factors among different symptom types of schizophrenia. Methods The con-centrations of AD7c-NTP in urine of 30 patients with positive symptoms,46 patients with negative symptoms and 24 controls were detected by enzyme linked immunosorbent assay( ELISA) . Positive and negative symp-tom scale ( PANSS) was used to assess schizophrenia patients. The correlation analysis was conducted be-tween the urine AD7c-NTP and demographic factors. Results The level of AD7c-NTP in urine of patients with negative symptoms((0. 88±0. 93) ng /ml)was higher than that in the patients with positive symptoms ((0. 50±0. 22)ng/ml,P<0. 05). The level of AD7c-NTP of in urine female patients((1. 16±1. 12)ng/ml) was higher than that in the male patients((0. 57± 0. 49)ng/ml,P<0. 01). AD7c-NTP levels in patients with a course of disease of more than 100 months((0. 96±0. 96)ng/ml) were higher than those in patients with a course of disease of less than 100 months((0. 60±0. 59)ng/ml,P<0. 05). The level of AD7c-NTP in pa-tients over 35 years old((0. 94±0. 96)ng/ml) were higher than that in patients under 35 years old((0. 62±0. 62)ng/ml,P<0. 05). The level of AD7c-NTP in patients with MMSE score of 0-22 points((0. 92±0. 80) ng/ml) were higher than that in patients with score of 23-29 points((0. 62±0. 74)ng/ml,P<0. 05). Before admission(at least 2 months),the level of AD7c-NTP in patients without persisting in taking drugs((0. 99± 0.95)ng/ml) was higher than that in patients with persisting in taking drugs((0. 62±0. 65)ng/ml,P<0. 05). The level of AD7c-NTP in schizophrenic patients was positively correlated with age and course of dis-ease( r=0. 29,0. 26,P<0. 05) ,and negatively correlated with smoking history and mini-mental state exami-nation( MMSE) ( r=-0. 13,-2. 41,P<0. 05) . Conclusion There is a difference in AD7c-NTP levels be-tween patients with positive and negative symptoms of schizophrenia. Gender,age,course of disease and anti-psychotics are important factors that affect AD7c-NTP levels in patients with schizophrenia.

ABSTRACT

BACKGROUND:During the outbreak of severe acute respiratory syndrome(SARS),certain people had been isolated by various reasons and appeared a series of psychological, physical and behavioral reactions. OBJECTIVE:To understand the different defensive features in people with different level of mental health in the isolated population, and explore the relationship between defensive style and mental health. DESIGN:An in investigative study taking the isolated population during outbreak of SARS as the subjects. SETTING:A psychiatric department of a military hospital. PARTICIPANTS:Totally 187 people of different sex,age and education, who were isolated during April and May 2003 due to SARS outbreak in a city of northwest China,were selected as the subjects. INTERVENTIONS:The 187 subjects,who were isolated due to SARS outbreak,were evaluated by using the symptom checklist(SCL 90) and defense style questionnaire(DSQ). RESULTS:About 36.4% people of this population had distinct mental or physical health problems that were characterized by anxiety,horror,depression,hostility and compulsion.There was difference in defensive styles between the high symptom group and low symptom group,among which the score of DSQ factors in the immature type of high and low symptom groups were 5.72± 1.56 and 4.35± 0.96 respectively while the scores in the intermediate type defense were 4.98± 1.44 and 3.72± 0.89 respectively(P< 0.01).Mental health problem was positively correlated with the application of immature defensive style,but had negative correlation with application of mature defensive means. CONCLUSION:There is difference in the defensive styles among the isolated people with different mental health status,and their defensive strategies are closely related to the mental health.
