Objective: To study the relationships among attributional style, self-efficacy and subjective well-being(SWB). Methods: 269 college students participated the study. Attributional Style Questionnaire , Self-efficacy Questionnaire and Subjective Well-being(SWB) Questionnaire were applied to the college students. Results: ① Attributional style predicated SWB, but three dimensions (internality-externality; whole-part; controllability-uncontrollability)of negative events were significant negative predicators of SWB. ② Self-efficacy was a significant positive predicator of SWB. ③ There were no differences in SWB between sexes and specialities. ④ There were significant differences in SWB between students with different self-efficacy levels, and the SWB of high self-efficacy group was better than that of the low self-efficacy group. Conclusion: College students'attributional style and self-efficacy impact their subjective well-being.Educators should cultivate students's positive attributional style and enhance their self-efficacy.

To explore the safety of ropinirole in the treatment of Parkinson′s disease( PD).A total of 221 PD patients participated in a multi-center,12-week randomized,bromocriptine-controlled,double-blind, double-dummy and parallel-group trial.The safety was assessed on the basis of adverse reactions , blood pressure,pulse,laboratory parameters and electrocardiography recordings.The incidence of adverse reaction was 34.9%in ropinirole group and 34.8% in bromocriptine group.And the frequency of adverse reactions had no inter-group statistical significance (χ2 =0.000,P=0.995).Ropinirole has an excellent profile of safety in the treatment of Chinese PD patients.

Objective To investigate changes in serum level of glial fibrillary acidic protein (GFAP) in patients with Parkinson disease (PD) and its clinical significance. Methods Serum GFAP was determined with sandwich ELISA for 82 patients with PD and acute cerebral infarction (ACI), as well as healthy normal controls. Patients with PD were then divided into two sub-groups in terms of their course duration, one with less than five years and the other with more than or equal to five years. Effects of course duration and age of the patients on their serum GFAP were analyzed. Results Serum level of GFAP was significantly higher in patients with PD [(1.628±0.104) μg/L] and ACI [(1. 637±0. 063 )μg/L] than that in healthy normal controls [ (0. 025±0. 003)μg/L, t = 82. 7, 142. 2, all P <0. 05 ]. But, there was no significant difference in serum GFAP between patients with PD and ACI ( t =0. 214, P > 0. 05 ). Serum level of GFAP in PD patients had no significant correlation with their age. There was no significant difference in serum GFAP between two sub-groups of patients with PD (P > 0.05 ). Conclusions Serum level of GFAP increased significantly in PD patients, as compared to healthy normal controls, but it is not specific. Serum GFAP in patients with PD maintained at certain high level with progression of the disease, indicating effect of astrocytes may persistently exist during the disease course.

One hundred patients with Parkinson's disease (PD) aged 60 and above treated with levodopa were enrolled in this cross section study.The general conditions,medication,unified Parkinson's disease rating scale (UPDRS) scores and the incidence of levodopa-induced dyskinesia (LID) were documented.The incidence rate of LID in this group of PD patients was 37.0％ (37/100).The incidence was significantly higher in patients with levodopa treatment ≥ 4 years than that in patients with levodopa treatment ＜ 4 years (55％ vs.26％,x2 =8.770,P =0.003).The incidence rate ofpeak dosage dyskinesia in tremor-dominant PD patients was lower than that in rigidity-dominant PD patients(x2 =4.399,P =0.036).The incidence rate of LID was correlated with the duration of levodopa therapy.Amantadine may reduce the incidence of off dystonia.

A cross sectional study of 769 patients was performed to evaluate the association of blood uric acid with coronary heart disease (CHD) in different metabolic disorders. It showed that uric acid was not independently associated with CHD. However, when the other abnormal metabolic factors were absent, uric acid might be related to CHD.

OBJECTIVETo observe the clinical efficacy of deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training for post-stroke dysphagia.

METHODSSixty cases of post-stroke dys phagia were randomly divided into an observation group and a control group, 30 cases in each one. Patients in the observation group, based on the regular acupuncture treatment, were treated with deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17), once a day, 30 min per treatment; also swallowing training was combined, twice a day, 20 min per treatment. Patients in the control group were treated with swallowing training. All the patients were treated with regular treatment of stroke. Six days of treatment were taken as one session, and totally 3 sessions were given with an interval of one day between sessions. The video fluoroscopic swallowing study (VFSS) dysphagia evaluation scale and Watian water swallow test (WWST) were evaluated before and after treatment also the clinical efficacy and the recovery time of two groups were compared.

RESULTSAfter treatment, the VFSS score in the observation group was significantly superior to that in the control group (P < 0.01); the WWST in the observation group was significantly superior to that in the control group (P < 0.01). The cured rate was 70.0% (21/30) in the observation group, which was significantly superior to 43.3% (13/30) in the control group (P < 0.01); the total effective rate was 86.7% (26/30) in the observation group, which was significantly superior to 66.7% (20/30) in the control group (both P < 0.01). The clinical recovery time in the observation group was significantly shorter than that in the control group (P < 0.01).

CONCLUSIONDeep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training could effectively improve post-stroke swallow function.

Objective To evaluate the effect of Parkinson's disease treatment guideline on the initial medicine therapy and to explore the impact of hospital grade level and type of insurance on the initial prescription for Parkinson's disease.Methods We identified 136 PD patients as part of a population-based study in Beijing and made a comparison between the patients with initial prescriptions of dopamine receptor agonists (DA) and levodopa (LD).Results Among 136 patients,excluding patients without initial medication of levodopa or dopamine receptor agonist,there were 61 cases with initial drug administration aged ≥ 65 years.Among the 61 cases,1 cases and 19 cases administrated dopamine receptor agonist and levodopa respectively before 2006,1 case and 11 cases respectively from 2007 to 2009,and 5 cases and 24 cases respectively after 2010.There was no significant difference in the percentage between patients with initial administration of levodopa and dopamine receptor agonist in the three periods (x2 =1.891,P =0.388).In 41 patients with initial drug administration of dopamine receptor agonist or levodopa aged＜65 years,1 cases and 23 cases administrated dopamine receptor agonist or levodopa respectively before 2006,0 case and 10 cases respectively from 2007 to 2009,and 3 cases and 4 cases respectively after 2010.There was significant differences in the percentage between patients with initial administration of levodopa and dopamine receptor agonist in the three periods (x2 =10.644,P=0.005).The percentage of patients with initial administration of dopamine receptor agonist aged＜65 years was increased after 2010 as compared before 2006 (x2 =7.219,P=0.028).There were no significant differences in the percentage of patients with initial administration of dopamine receptor agonist between grade 3 and non-grade 3 hospitals (13.6％ vs.6.3％,x2=0.675,P=0.686)and between patients with and without insurance (13.1％ vs.10.0％,x2=0.141,P=1.000).Conclusions The percentage of patients with initial administration of levodopa and dopamine receptor agonist has no significant difference between patients with initial drug administration aged ≥ 65 years before and after the introduction of Parkinson's disease treatment guideline,while the percentage is increased in patients with initial drug administration aged＜65 years.No impact of hospital grade level and type of insurance on initial administration for Parkinson's disease is found.

Objective To investigate emotion recognition in music in patients with idiopathic Parkinson's disease (PD),and to further explore its relationship with executive function and related factors.Methods Twenty-four PD patients enrolled from the Department of Neurology,Beijing Hospital between January and June 2014 and 24 matched healthy controls were tested using 24 musical excerpts that expressed happiness,sadness,fear or anger.The two groups were tested for executive function using a simplified trail making test and a clock drawing test.All the patients were rated on the Hoehn-Yahr stage,the Unified Parkinson' s Disease Rating Scale (UPDRS) Ⅲ,the Hamilton Rating Scale for Anxiety (HAMA) and the Hamilton Rating Scale for Depression (HAMD).Results In trail making test,PD patients worked slower ((51.58 ±33.14) s) than controls ((34.46 ± 19.64) s) (t =2.178,P =0.036).PD patients got more errors (0 (QL =0,QU =2.5)) than controls (0 (QL =0,QU =0);Z=-2.372,P =0.018).In clock drawing test,PD patients got lower score (2.63 ±0.65) than controls (2.96 ±0.20)(t =-2.407,P =0.023).The difference between two groups was not statistically significant in the recognition of happy,sad,fear or anger music (all P ＞ 0.05).In PD group,the scores of the recognition of happy,sad music and the total score of musical emotion recognition were associated with the time of trail making test (r =-0.560,-0.572,-0.530,P =0.004,0.003,0.008),while not related to age,disease duration,education duration,the scores of Minimum Mental State Examination,the scores of UPDRS Ⅲ,Hoehn-Yahr stage,the scores of HAMA,the scores of HAMD,LDE,the scores of clock drawing test or musical background (all P ＞ 0.05).Conclusions PD patients are not impaired in emotion recognition in music in this study.The relationship between musical emotion recognition and executive function is unclear.

Objective To investigate the prevalence of Helicobacter pylori (HP) infection in patients with Parkinson's disease (PD), and analyze the relationship of HP infection with the symptoms, disease progression and motor complications of PD.Methods 72 PD outpatients were randomly selected, and 100 gender and age-matched subjects who took health physical examination were considered as healthy controls.Basic data were collected and estimated by Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn and Yahr stage, the 39-item Parkinson' s Disease Questionnaire (PDQ-39), Activity of Daily Living Scale (ADL), Minimum Mental State Examination (MMSE), Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA).All subjects underwent 13C-urea breath test to determine Helicobacter pylori infection status.Results There was no significant difference in H P infection rate between PD and control groups [37.5 ％ (27 cases)vs.32.0％ (32 cases), P=0.45].According to the initial symptoms, PD patients were divided into two groups: bradykinesia/ rigidity group and tremor group.The HP infection rate was higher in bradykinesia/rigidity group than in tremor group [52.2％ (12 cases) vs.30.6％ (15 cases)], but had no significant difference (P=0.08).The mean HY stage was higher in the HP-infected patient group than in the non-infected group [(2.6±0.7) vs.(2.2±0.9), P=0.03].The HP infection rate was higher in patients with HY stage ≥2 than with HY stage ＜2 [46.4％ (26 cases) vs.6.3％ (1 case),P=0.003].There were no correlations of HP infection with gender, age, age of onset, UPDRS, UPDRS-Ⅲ, PDQ-39, the course of the disease, wearing-off phenomenon, and dyskinesias.Conclusions The PD patients with HP infection are mainly at middle-and late-stage.HP infection may be related with the progress of the disease.It needs further study and validation by expanding the sample to investigate whether HP infection affects the motor complications.
