Objective To study the effect of simvastatin combined with trimetazidine on cardiac function and high-sensitivity C-reactive protein(hs-CRP) in patients with chronic heart failure.Methods 160 patients with chronic heart failure were divided into control group and the observation group according to the random number table.The control group was treated with diuretics,inotropic,vasodilators and other conventional treatment,on the basis of this,the observation group received simvastatin combined with trimetazidine treatment.The cardiac function and hs-CRP of the patients were observed,and the treatment effects were evaluated and analyzed.Results The total effective rate of the observation group was 82.50％,which was significandy higher than 52.50％ of the control group (x2 =16.4103,P ＜ 0.001).Compared with before treatment,IL-6,TNF-alpha and hs-CRP levels of two groups after treatment were significantly decreased (t =12.234,13.342,5.463,8.533,7.896,3.536,all P ＜ 0.05),and those in the observation group were significantly lower than the control group (t =4.653,3.976,3.674,all P ＜ 0.05).Conclusion Simvastatin combined with trimetazidine has good effect on the cardiac function of patients with chronic heart failure,and can effectively reduce the level of hs-CRP,it is worthy of clinical application.

Objective To explore the mental-behavior characteristics in serious internet game addicts.Methods To investigate internet addiction questionnaire, EPQ, social support questionnaire, purpose in life test and sensation seeking scale in 30 serious internet game addicts ( age from 16 ～ 25 years) and 43 non-addicts.Results Internet addicts have obviously lower social support questionnaire score, subjective support score, purpose in life test score and sensation seeking TAS score than non-addicts( P<0.05 or P<0.01 ). Objective support score, the use score for social support and sensation seeking score can forecast the internet addiction extent of the internet addict group. Internet addicts have obviously lower L score of EPQ than non-addicts ( P<0.01 ). There is the negative correlation between N score of the internet addicts and sensation seeking score( r=-0. 452, P<0.05). Conclusions Serious internet game addicts have the metal characteristics of low social support, low purpose in life and low adventure; sensation seeking and social support scale have prognosticative function for internet addiction degree; serious internet game addicts of low N score have high sensation seeking characteristic.

Objective This study aims to develop a lottery addiction scale (LAS) for Chinese welfare lot-tery buyers. Methods A scale made by authors was applied to 8238 welfare lottery buyers from 31 provinces,one sample of 4071 cases for exploratory factor analysis (EFA) ,and the other 4167 cases for confirmatory factor analy-sis (CFA). Results Through EFA, the scale consisted 10 items established, and it was divided into two factors: functional impairment and emotional dependency. These two factors could explain 45.5% of total variance, The scale was confirmed by CFA (X2/df=13.34 ;IFI=0.96 ;CFI=0.96 ;NFI=0.96 ;RSMEA = 0.054). The internal consistencies of the scale answered to the basic statistic criterion (r=0.59～0.74). Criteria validity shown by higher LAS scores in high expending group than low expending group was also satisfying. Conclusion The LAS has good psychometric features and could be applied to Chinese lottery buyers.

Objective To study early face processing of internet addiction patients by using ERP method. Methods Ten healthy young man 18~21 years and 10 internet addiction patients 17~22 years served as subjects in experiment. Two runs of 300 stimuli (duration: 50 ms) of 3 facial and 3 non-facial pictures were randomly presented with equal probability (ISI: from 1 000 ms to 1 500 ms randomly), and the subjects were asked to react to facial stimuli and non-facial stimuli by pressing the left button and right button respectively as quickly as possible. Thirty two channel electroencephalogram (EEG) was recorded by Neuroscan Nuamps System. Results 1) Specific-face component Nd170 (face N170 minus object N170) was found in both groups, which was distributed at the temporal-occipital region in control groups but at occipital region in internet addiction group; 2) Compared with Nd170 in internet addiction group, Nd170 was significantly lower at occipital negion and delayed in control group. Conclusion The early face processing mechanism of internet addiction patients may be different from normal people.

Objective: To test the reliability and validity of a questionnaire on knowledge, beliefs and intentions about AIDS/safe sex for university students.
