Objective To investigate the cognitive impairment characteristics in Parkinson's disease (PD) with mild cognitive impairment(PD-MCI)as well as their related risk factors.Methods In all of the participants, a battery of neuropsychological tests were selected to identify the cognitive deficits; the 2 cognitive screening tests utilized in this study were the MMSE and the CAMCOG-C; the severity of disease was measured using the Hoehn-Yahr;the motor portion of the UPDRS and Webster scale were used to evaluate motor function and PD-MCI were classified according to modified Petersen's criteria.Results Of the 89 PD cases, 56 (63%) were cognitively normal (PDCOGNL), 20 (22%) had MCI and 13 (15%) met criteria for PD dementia (PDD). The cognitive domain abnormal in PD-MCI was orientation, language, memory, attention, praxis, thinking and perception. The PDCOGNL group had no significant differences in age and PD onset versus the PD-MCI group, but had significant difference in the years of education (PD-MCI:4.4±4.3,PDCOGNL:7.1±4.9;q=3.270, P<0.05); PD-MCI also had no significant differences for all of them versus the PDD, but the PDD group had significant differences for them (q=-4.913, -4.997, 4.740,all P<0.01) compared with the PDCOGNL group; there were no significant differences among 3 groups in years of PD duration. Hoehn-Yahr and Webster scale, UPDRS-motor score had negative correlation with PD cognitive function. Conclusions A stage of clinical cognitive impairment in PD can be defined between PDCOGNL and PDD that characterized as PD-MCI. There are multiple domains impaired in PD-MCI. The risk factors of PD cognitive impairment include the elder, later onset and lower education level. There are negative correlation between the severity of disease, motor function and PD cognitive function.

[Objective] To observe the effect of prescription of dredging intestines to dispel heat for enema on serum C-reactive protein content in acute abdomen (AA) induced by pyemia. [Methods] Fifty-seven cases of AA induced by py-emia were randomly allocated to two groups. On the basis of routine operation and application of antibiotics, Group A was treated with prescription of dredging intestines to dispel heat for enema and Group B with saline enema additionally. Therapeutic effect and C-reactive protein content in the two groups were observed and compared. [Results] All the cases in the two groups were cured. C-reactive protein content in Group A were decreased obviously in the 7th day after treatment (P

Objective To investigate the prevalence of nutritional risk,undemutrition,overweight/obesi-ty,and apphcation of nutrition support in departments of neurology in 3 metropolitan hospitals in Beijing. Methods Adult patients in the departments of neurology from 3 metropolitan hospitals in Beijing were consecutively en-rolled from March 2005 to March 2006.Nutritional Risk Screening 2002(NRS2002)score≥3 was defined a8 nu-tritian risk,while body mass index(BMI)<18.5 ks/m2 as undemutrition.NRS2002 was performed on the next morning of admission and nutritional support evaluation was performed on the 14th day of admission or discharge day.The relationship between nutrition risk and nutrition support was analyzed.Results A total of 753 patients were enrolled.NRS2002 scoring results were obtained in 461 patients.The prevalence of undemutrition was 4.2%and nutritional risk Was 21.2%.Among them 292 cases in undemutrition category were estimated by semm albu-min<30g/L without accurate BML If the cases without accurate BMl were excluded,the prevalence of undemutri-tion was 5.4%and nutritional risk Was 10.8%.Twenty-three patients(14.4%)with NRS2002≥3 received nutrition support.Thirteen patients(2.2%)with NRS2002<3 received nutrition support.The average PN:EN ratio Wag 1:2.Conclusions A large proportion of inpatients were at nutritional risk or undemutrition in the de-partments of neurology in metropolitan hospitals in Beijing.The application of nutrition support Wag somehow inap-propriate in these patients.Evidence-based guidelines are required to improve this situation

Objective To investigate the correlation between the frustration tolerance and personality of medical college students and to discuss its promoting strategies.Methods Totally 460 college students were selected randomly.Questionnaire of frustration tolerance and scale of Eysenck personality inventory(EPQ) were used and the measurement data were compared with correlation analysis and regression analysis of SPSS 13.0.Results Correlation was significant between frustration tolerance (total score and 6 inducing factors) and personality (EPQ factors) of college students ； personality (EPQ factors)of students could predict their frustration tolerance and corresponding t value was -4.85,P ＜ 0.01 (psychoticism),6.93,P ＜ 0.01 (extraversion),-11.15,P ＜ 0.01 (neuroticism).Conclusions Personality of college students are greatly influenced by their frustration tolerance.Targeted anti-frustration ability training should be conducted according to the different personality characteristics.

ObjectiveTo explore the relationship between male adolescents' childhood abuse and externalizing behaviors,and the moderating effect of monoamine oxidase A (MAOA) gene promoter region variable number tandem repeat (VNTR) polymorphism.MethodsThrough random cluster sampling,352 Han male middle school students from Changsha were tested by Achenbach child behavior checklist-youth self reports (CBCL-YSR)and childhood trauma questionnaire-28 item short form (CTQ-SF),their MAOA genotypes were also identified.A hierarchical multiple regression analysis was used to test the moderating effect.Results ( 1 ) Compared participates with high activity MAOA gene and that with low activity MAOA gene,there were no significant differences on age ( ( 15.82 ± 1.52) vs ( 15.94 ± 1.62 ) ),externalizing behaviors ( ( 15.13 ± 10.14 ) vs ( 14.33 ± 9.70 ) ),total abuse ( (52.59 ± 10.46) vs (51.39 ± 7.56 ) ),emotional abuse( ( 7.63 ± 3.31 ) vs ( 7.11 ± 2.68 ) ),physical abuse ( ( 6.40 ± 2.82) vs (6.12 ± 2.05 ) ),sexual abuse ( ( 6.42 ± 3.24 ) vs ( 5.94 ± 1.72 ) ),emotional neglect ((13.44±5.12) vs (13.16 ±4.83) ),physical neglect( (10.27 ±2.64) vs (10.44±2.53))(t=-1.789～0.678,P ＞ 0.05 ).(2)Except emotional neglect and physical neglect,emotional abuse,physical abuse and sexual abuse could predict externalizing behaviors( Sβ =0.141 ～0.347,P ＜ 0.01 ).(3) MAOA gene was not directly related to externalizing behaviors( Sβ =- 0.023,P ＞ 0.05 ).There was a significant interaction between MAOA gene and emotional abuse( Sβ =-0.148,P ＜ 0.01 ).The interaction between MAOA gene and physical abuse or sexual abuse showed no statistical significance( Sβ =- 0.067,- 0.005,P ＞ 0.05 ).ConclusionMAOA gene polymorphism can moderate the relationship between male adolescents'childhood emotional abuse and externalizing behaviors.

Objective:To investigate the role of anaphylatoxin C 5 a in patients with asthma .Methods:A prospective study was performed between September 2006 and February 2007.A total of 33 patients with acute exacerbation of asthma and 13 healthy subjects were recruited into the study .The patients with acute exacerbation of asthma were also studied when they returned to the remission state .Levels of lung function, levels of C5a in induced sputum and cell differential count in induced sputum were determined . Results:The level of C5 a in induced sputum was significantly higher in patients with acute exacerbation of asthma [0.85(0.68-2.13) μg/L] than that in patients with stable asthma [0.45(0.26-0.88)μg/L, Z=-2.193, P=0.013];Sputum C5a levels in stable asthma patients were significantly higher than those in healthy controls [0.14(0.06-0.45) μg/L, Z=-2.141, P=0.015].The level of C5a in patients with severe exacerbation [2.21(1.27 -9.0) μg/L] was significantly higher than those in patients with mild exacerbation [0.34(0.17-0.63) μg/L] and moderate exacerbation [0.85(0.55-1.67) μg/L,χ2 =12.330, P=0.001].The level of C5a in induced sputum was positively correlated with the number of total cells count (r=0.797, P=0.004), neutrophils (r=0.504, P=0.032) and macrophages ( r =0.424, P=0.036 ) in acute exacerbation of asthma .Conclusion: C5a levels in induced sputum could be identified as an important prognostic biomarker , which involved in asthma ’ s pathogenesis .
