There were 2 of complete remission (CR) , 10 of partial remission (PR), 3 of stable disease (SD). All patients are still alive now, the lougest follow-up time is 20 months, and the shortest is 6 months, the average followed span is 12 months. Conclusion CT guided 125I seeds implantation is a safe and effective method in the treatment of liver metastasis caused by colorectal cancer.

Objective To study the relationship between mental effort and personal time perspective during the process of individual changing bad habits.Methods 230 graduate students were collected to attend this longitudinal study of 21 days by experience sampling method.The data on mental effort and performance were obtained from the process of daily change of the bad behavior.Zimbardo Time Perspective Inventory (ZTPI) was applied to graduate students.The survey results were analyzed by hierarchical linear modeling (HLM).Results In 21 days,the mental effort of subjects showed very clear downward trend,the trend of the change was statistical significant (total score(5.63±2.62),t=-5.590,P＜0.01).Mental effort didn't have significant difference in five kinds of behavioral objectives (keeping early hours,exercising daily,dieting,reading daily,limiting screen time) (P＞0.05).The male obviously put more effort than the female during the study(t=2.743,P＜0.01).Both Present Hedonism and Futurism were inversely related to mental effort,which was statistical significant (t=-2.504,P＜0.05;t=2.39,P＜0.05).Both Present Fatalism and Futurism had the effects on the changing trend of the mental effort regulatory,which was statistical significant (t=-3.099,P＜0.01;t=-2.400,P＜0.05).Conclusion The mental effort of changing the behavior will gradually decline during the process of habit establishment.The mental effort of subjects who had present fatalism or futurism show a faster decline.

Objective To study the effect of parenting styles on the children' s self-control,and distinguish the influence between father and mother.Methods The present study selected 1 531 children (766 girls) between 3-10 years old.Data on parenting style were collected by parenting style questionnaire,while data on children' s self-control were measured by dual-system of self-control scale.Principal component analysis was conducted to examine common method bias.Results (1) No common method bias was found in this study.(2) Boys scored (31.66±5.95) on control system lower than girls (32.91±5.49),t=4.071,P＜ 0.01,but they had higher scores (43.19±8.32) on impulsive system than girls (41.96±8.32),t=2.226,P=0.027.(3)The associations of children's self-control scores with parents' spoiling,neglectful,authoritarian,inconsistent style were significant (r=-0.054～-0.174,P＜0.05),while it correlated positively with parents' democratic style (r=0.231,r=0.243,P＜0.05).The correlation between children's impulsive system scores and parents' spoiling,neglectful,authoritarian,inconsistent style were significantly positive (r=0.116-0.195,P＜0.05),while its associations with parents' democratic style were significant (r=-0.107,r=-0.108,P＜0.05).(4) As controlling children's age and sex,father democracy (β=0.120),inconsistency (β=-0.159),and mother democracy (β=0.188) were significantly correlated with children' s self-control (R 2adj =0.107,P＜0.05).Father despotism (β=0.070),inconsistency (β=0.136),mother's democracy (β=-0.063),despotism (β=0.099) and inconsistency (β=0.061) significantly predicted children's impulsive system (R 2adj =0.082,P＜0.05).Conclusion Each dimension of self-control and parenting style is high correlation.Father and mother's different rearing traits and the combination of different rearing traits contributed variously to children' s self-control system.

Objective To explore intervention efficacy of clinical application of antimicrobial agents in internal medicine departments of a hospital.Methods 1 880 medical records from internal medicine and pediatrics departments this hospital in July-December 2010 were randomly selected as control group (before intervention),and 2 207 medical records in July-December 2011 were as trial group (after intervention),antimicrobial use of two groups was compared.Results The over-all usage rate of antimicrobial agents after intervention was lower than before intervention (48.12% vs 58.62%,χ2 =44. 45,P <0.001).Except endocrinology,pediatrics and hematology departments,the usage rates of antimicrobial agents in the other departments after intervention were all obviously lower than before intervention(all P <0.05).The usage rate of antimicrobial agents in endocrinology and hematology departments were both low(<40%),which met the requirements of Ministry of Health.Conclusion Comprehensive intervention in clinical use of antimicrobial agents reduced the usage rate of antimicrobial agents in internal medicine and pediatrics departments in this hospital.

Objective To develop a scale of the executive functional status for adolescents.Methods Regarding to the structure and the conception of executive function and the results of interviews to several adolescents,a preliminary inventory including 37 items was developed.The investigation sample consisted of 1722 students from 2 provinces in China by stratified sampling,and the the internal consistency,conduct validity and criterion validity were assessed by exploratory factor analysis.Results The revised scale including 21 items was consisted of three factors:inhibition control,cognitive flexibility,working memory,which explained 45.39％ of the total variance.The factor loading ranged from 0.499 to 0.727.The Cronbach alpha ranged from 0.786-0.897 for the scale and its three factors.Factor structure fitted actual data and its fit indices were x2=530.44,df=186,RESMA =0.053,GFI =0.93,AGFI =0.91,NFI =0.96,CFI =0.97.Conclusion It shows that the reliability and validity of the scale meet the standard of the psychometrics,and it can be suitable for evaluating the functional status of execution of Chinese adolescent.

Objective To investigate the incidence of attention deficit hyperactivity disorder (ADHD)symptoms among 3-10-year-old children and its relationship with sleep.Methods Taking gender,grade (junior in kindergarten to third grade),and region(urban and rural areas) as stratification variable,1 535 children aged 3 to 10 years old were selected by random in six areas nationwide.ADHD Rating Scale-Ⅳ-Parent Version and Pittsburgh Sleep Quality Index were adopted to investigate ADHD symptoms and sleep of these children.Results 24.95％ of the investigated children had ADHD symptoms.Boys scored higher than girls in all indicators(boys:Inattention (IA):(9.21±3.75),Hyperactivity-Impulsivity (HI):(8.62± 3.87),Total:(17.82±7.01),girls:IA:(8.16±3.77),HI:(7.32±3.76),Total:(15.48±6.98)) while girls had higher incidence of ADHD symptoms than boys (girls:IA:16.19％,HI:27.02％,Total:32.51％,boys:IA:11.70％,HI:8.19％,Total:17.43％).Peak incidence occured in children aged 7-9 (7 years old group:IA:18.22％,HI:21.93 ％,Total:38.66％,8 years old group:IA:20.66％,HI:23.25 ％,Total:38.01％,9 years old group:IA:18.22％,HI:33.78％,Total:32.00％).Rural children had higher incidence of ADHD symptoms than urban children(rural children:IA:18.37％,HI:18.37％,Total:29.48％,urban children:IA:10.47％,HI:15.12％,Total:21.40％).Logistic regression results showed that sleep quality,sleep disorder and daily dysfunction can predict the incidence of ADHD symptoms to a certain degree.Conclusion The incidence of ADHD symptoms appear to be high in children evaluating by ADHD Rating Scale-Ⅳ-Parent Version.More attention should be paid to girls and rural children' s ADHD symptoms.7-9 years old children have the highest incidence of ADHD symptoms.The more problems in daytime dysfunction,sleep disorders and bedtime,the more ADHD symptoms will be observed.
