And some behavior risk factors, such as fatness, lack of outdoor exercise in the community members. Thus, the major necessary health service of Peking University Health Science Center residents is to carry out a comprehensive management program of life way disease for the whole people.

Objective To investigate the factors related to the depression in the retired old army officers in Beijing, to establish effective nursing intervention on these factors. Methods Various factors related to depression were investigate using questionnaire in 500 retired army officers. Results Among 500 subjects, 23.0% (115/500) were with minor depression, 6.4% (32/500) with moderate depression, while 1.6% with severe depression. Subjects whose wife were still alive had much less incurrence rate of depression than ones remarried or widowed. The less time after retirement and less satisfaction in life were other important factors related to depression. Conclusion Psychological care should be emphasized on widowed, freshly retired, or people feeling less satisfactory in life. Active nursing intervention should be applied to lower the harmful effect of depression on health.

Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

Objective To investigate the characteristics and relationship of cognitive function and resting state functional magnetic resonance imaging(fMRI) amplitude of low-frequency fluctuations (ALFF)in childhood and adolescence-first-onset obsessive-compulsive disorder(OCD).Methods Twenty-four childhood and adolescence-first-onset OCD patients (patient group) and thirty-three age/gender/education-matched healthy controls (healthy control group) were enrolled in this study.The participants' cognitive function was tested with trail making test (TMT),symbol coding,Hopkins verbal learning test-revised (HVLT-R),brief visuospatial memory test-revised (BVMT-R),verbal fluency test (VF),digital span test,maze test and Stroop test.Then a resting-state fMRI scan was conducted for each participant.Amplitude of low-frequency fluctuation approach was used to explore the differences of resting-state brain function between patients and controls,and analyze the significant brain regions by adopting t test.The cognitive functions of patients and healthy control group in the significant brain regions were compared by using Pearson correlation analysis.Results The patient group had lower scores than healthy control group in symbol coding,BVMT-R and digital span test,and the differences were statistically significant [(45.24 ± 10.32)scores vs.(56.85 ± 9.57) scores,(21.94 ± 6.99) scores vs.(30.58 ± 3.92) scores,(64.06 ± 20.00) scores vs.(78.03 ±18.08) scores;t =3.96,4.90,2.50;all P ＜ 0.05].Corrected by Alphasim,patient group showed significantly increased ALFF in the left and fight temporal lobe,left and fight posterior lobe of cerebellum,right middle temporal gyrus,but ALFF decreased in the area of left and right lenticula,left putamen compared with the healthy control group (all P ＜ 0.05).The patients group showed that TMT scores were positively correlated with the value of ALFF in the right temporal lobe (r =0.67),and color scores were positively correlated with the value of ALFF in the right middle temporal gyrus (r =0.53),but colour scores were negatively correlated with the value of ALFF in the right tcmporal lobe (r =-0.54);the healthy control group showed that BVMT-R and digital span test scores were positively correlated with the value of ALFF in the left temporal lobe (r =0.47,0.41),but digital span test scores were negatively correlated with the value of ALFF in the right temporal lobe (r =-0.49),and colour scores were negatively correlated with the value of ALFF in the left temporal lobe (r =-0.35),while word and color-word scores were negatively correlated with the value of ALFF in the right middle temporal gyrus (r =-0.39,-0.36);the correlation coefficient above had statistical significance (all P ＜ 0.05).Conclusions The childhood and adolescence-first-onset OCD patients had cognitive impairment,including speed of processing,visual learning and memory,working memory;and the patients showed abnormal spontaneous neural activity at some brain regions.The cognitive dysfunction may be associated with abnormal spontaneous neuronal activity in childhood and adolescence-first-onset OCD.

OBJECTIVE:To observe the effects of remifentanil-induced controlled hypotension (CH) on postoperative cogni-tive dysfunction (POCD) and serum S100β protein in elderly patients underwent spinal surgery,and to investigate their relation-ship. METHODS:Sixty elderly patients undergoing selective laminectomy decompression internal fixation of lumbar or thoracic fractures under general anesthesia were selected prospectively from orthopedics department of our hospital during Jan. 2014-Dec. 2015,and then divided into CH group and non-CH group in accordance with random number table,with 30 cases in each group. Both groups received general anesthesia of injection and inhalation via endotracheal intubation. Mean arterial pressure (MAP) of CH group were reduced to 70%-80%of the basic values by adjusting remifentanil infusion rate;those of non-CH group were main-tained at basic level. Surgery duration,anesthesia duration,intraoperative blood loss,the incidence of POCD and serum concentra-tion of S100β protein were observed in 2 groups. The relationship of serum concentration of S100β protein with POCD was ana-lyzed,and the occurrence of ADR was recorded. RESULTS:The intraoperative blood loss of CH group was significantly less than that of non-CH group,with statistical significance (P<0.05). There was no statistical significance in the incidence of POCD be-tween 2 groups on the 1st and 7th day after surgery(P>0.05). The incidence of POCD and serum concentration of S100β protein in CH group were significantly higher than in non-CH group on the 2nd and 3rd day after surgery,with statistical significance(P<0.05). The serum concentration of S100β protein may be related to the incidence of POCD (r=0.992 7,P=0.001 3). CONCLU-SIONS:Remifentanil CH used in elderly patients underwent spinal surgery can reduce intraoperative blood loss,but increase the se-rum concentration of S100βprotein and the incidence of POCD at early stage.

Objective To study the effect of parecoxib sodium preemptive analgesia on the postoperative cognition and inflammatory cytokines in elderly patients.Methods Sixty elderly male patients undergoing replace-ment of total hip were randomly divided into two groups:the control group(group C,30 cases) and the parecoxib sodi-um group(group P,30 cases).In group C,physiological saline 5 ml was injected after induction of anesthesia.Pare-coxib sodium 40 mg was injected after induction of anesthesia in group P.Peripheral venous blood was collected at the following time points:2h before operation(T0 ),and 4h(T1 ),24h(T2 ) and 48h(T3 ) after operation.And the serum concentrations of IL -1β,IL -6,tumor necrosis factor α(TNF -α) were measured by enzyme linked immunosorbent assay(ELISA).Cognitive function was assessed by mini -mental state examination(MMSE) at the time of T0 -T3 . Results The MMSE scores in group P[(25.4 ±0.6) points,(27.2 ±0.1)points] were significantly higher than those in group C at T1 and T2 .The concentrations of IL -1β,IL -6 and TNF -αin group P[T1:(18.43 ±4.45)pg/mL, (165.34 ±9.57)pg/mL,(34.43 ±3.83)pg/mL;T2:(14.59 ±2.59)pg/mL,(98.99 ±7.28)pg/mL,(22.32 ± 3.81)pg/mL]were lower than those in group C[T1:(23.97 ±3.85)pg/mL,(204.19 ±12.44)pg/mL,(37.77 ± 4.81)pg/mL;T2:(19.33 ±3.18)pg/mL,(121.35 ±9.67)pg/mL,(29.01 ±3.39)pg/mL]at T1 ,T2 .The concen-trations of IL -1β,IL -6 and TNF -αand the MMSE scores had no differences in group P and group C at T3 .The concentrations of IL -1β,IL -6 and TNF -αin group P at T1 and T2 [(9.57 ±2.24)pg/mL,(46.15 ±6.18)pg/mL, (14.48 ±3.14)pg/mL] were lower than those at T0,and had no difference at T3 .Conclusion Parecoxib sodium preemptive can reduce the incidence of POCD in elderly patients by inhibiting the release of early postoperative pro -inflammatory cytokines.

Among these patients, more than 80% were able to have a stable emotion, regular daily life, stop smoking and less drinking, there were 66% cases with a healthy diet. The systolic pressure of the patients declined significantly after health education (P<0.01).Conclusion The health education is an efficient way to control hypertension in the official-service outpatient department.

Objective To study the correlation between the locus of control and career adaptability and career decision-making self-efficacy of nursing students. Methods Totally 500 nursing students from four tertiary hospitals of our province were randomly selected as the investigation object. A total of 500 questionnaires were sent out, invalid questionnaires were excluded, 498 valid questionnaires were recovered, the effective recovery rate was 99.6%. The scores of the subjects were investigated by using the Locus of Control Scale, the Career Adaptability Scale and the Career Choice Efficacy Scale as the evaluation tools. Results The overall average score of the ability of locus of control was higher in this investigation. The overall average score of career adjustment strength was (3.93±1.27) points, which was at a high level. The total score of the career efficacy scale was (3.36±1.17) points. Nursing students in each dimension of career adaptability and internal control had a significant positive correlation (r=0.119-0.241, P<0.05), the correlation existed only between career control and external control type (r=0.134, P<0.05). There were significant positive correlations between the dimensions of career self-efficacy and internal control in occupational nursing students (r=0.102-0.146, P<0.05), but there was no correlation with external control (P>0.05). Conclusions The locus of control and nursing students' career adaptability and career decision-making self-efficacy are closely related, improve the locus of control, and promote the transformation of nursing students attribution from exterior to interior, is the key process of cultivating correct career motivation and career transition for nursing students.
