Objective To explore the factors affecting the quality of life in patients with Parkinson's disease(PD).Methods The quality of life,severity of disease,activities of daily living,motor responses,mental state and the complications of treatment in 71 patients with PD were evaluated by the PD Quality of Life Questionnaire(PDQL),Unified PD Rating Scale(UPDRS),the Hoehn-Yahr scale,the Schwab and England disability scale,the Hamilton Depression Rating Scale for Depression(HRSD),and meanwhile factors such as age,gender,age of onset,the beginning symptom,the location of onset,smoking,doses of L-dopa and fluctuations etc were evaluated by some methods.Results Bivariate analysis showed that the longer course of disease and treatment,the more doses of L-dopa,the higher scores of UPDRS and the Hoehn-Yahr scale,and depression fluctuations with patients,the worse quality of life they had(P

BACKGROUND:Psychiatric patients are the high risk group of people who are liable to commit suicide.Recently,research on neurobiology and genetics of suicide mainly concentrates in the study of 5 hydroxytryptamine(5 HT) system.It is found that T102C polymorphism of 5 HT2A receptor gene is associated with suicide in depressive patients. OBJECTIVE:To investigate the correlation of A 1438G polymorphism of 5 HT2A receptor gene with attempted suicide in psychiatric patients. DESIGN:An observational comparative study of taking the patients as subjects and healthy physical examinee as the controls. SETTINGS:A psychiatric department in a municipal hospital and a neurological department in a university hospital. PARTICIPANTS:All the samples in the research were collected from the Department of Psychiatry of Yangzhou Wutaishan Hospital from March to September 2002.Analysis of genotype was completed in the Neurobiological Laboratory of Xuzhou Medical Institute from October to December 2002.Inclusive criterion:patients met the diagnostic criteria of schizophrenia or affective disorder in the third edition of the Chinese Classification and diagnostic criteria of Mental Disorders(CCMD 3) and Diagnostic and Statistical Manual of Mental Disorders Fourth Edition(DSM IV).Exclusive criterion: parasuicider with idea or behavior of hurting oneself,but without intention to die.According to whether there was suicidal behavior or intention,116 patients were divided into 2 groups:attempted suicide group[n=52,35 males and 17 females,with an average age of (44± 13) years old] and no suicide group [n=64, 44 males and 20 females, with an average age of (48± 15) years old].Other 63 cases were taken as the normal controls[33 males and 30 females, with an average age of (55± 17) years old]. INTERVENTIONS:DNA of all the participants was extracted with the routine method of chloroform saturatedphenol leukocyte pheresis.The polymorphism of 5 HT2A receptor gene was analyzed with the restriction fragment length polymorphism. RESULTS:The G allele frequency of A 1438G polymorphism in the attempted suicide group(0.52) was significantly higher than that in the normal control group(0.39)(χ 2=3.91,P< 0.05).There were significant differences in the distribution of the 3 genotypes of AA, AG and GG between the attempted suicide group(0.23,0.50, 0.27) and normal control group(0.32, 0.59, 0.09)(χ 2=6.12,P< 0.05). CONCLUSION:Attempted suicide of psychiatric patient is associated with A 1438G polymorphism of 5 HT2A receptor gene.G allele may be a risk factor for the attempted suicide of psychiatric patient.
