Objective To inquire the nutritional and immune status in patients with gallbladder carcinoma before and after radical cholecystectomy.Methods The nutritional and immune status in patients with gallbladder carcinoma were assessed in 1 week before surgery, and on 3rd day, 7th day, 14th day and 21st day after operation, respectively.Results All of the nutritional parameters but the serum level of iron, TIBC and transferrin recovered within 3 week after operation. Remarkable decrease of serum IgG, IgA, IgM and C3, C4 complement, IL-2, CD4, CD4/CD8 ratio, and the remarkable increase of serum SIL-2R and CD8(P＜0.01) on 3rd day after operation.Conclusion Adequate iron should be supplemented after the radical cholecystectomy for gallbladder carcinoma in the third postoperative week. Radical cholecystectomy with complete resection of the tumor and removal of lymph nodes played the important roles in the recovery of immune function.

Objective To investigate the effect of neurofeedback training for tics symptoms and electroencephalogram (EEG) spectrum change in children with tic disorder.Methods 19 patients with transient tic disorder (TTD),20 with chronic motor or vocal tic disorder (CTD) and 15 with Tourette' s disorder (TS) received 40 sessions of neurofeedback training.The clinical effect was evaluated with Yale Global Tic Severity Scale,and brain activity improvement with EEG theta/beta,theta / sensorimotor rhythm (SMR) power ratio.Results The patients with three types of tic disorder all showed a reduction of tics symptoms (TTD:10.32 ± 0.82 vs.5.91 ± 5.74;CTD:12.35 ±1.50 vs.4.00 ±2.22; TS:25.33 ±2.80 vs.13.73 ±4.22; P＜0.01).Additionally,the patients showed theta decreasing and SMR enhancing after the sessions.The ratio of theta/beta (TTD:2.52 ±0.38 vs.2.33 ±0.32;CTD:2.43 ±0.39 vs.2.21 ±0.30; TS:2.64 ±0.35 vs.2.39 ±0.26) and theta/SMR was significantly lower than before treatment (P ＜ 0.01).Conclusion Neurofeedback training is an effective and valuable treatment in tic disorder especially in the patients with transient tic disorder and mild chronic motor or vocal tic disorder.

Objective To investigate the cognitive impairment and time-on-task characteristics of combined type(C type) and predominantly inattentive type (Ⅰ type) of children with attention deficit hyperactivity disorder(ADHD).Methods 24 cases with C type ADHD,20 cases with Ⅰ type ADHD and 24 normal children were completed 2 Block period of continuous performance test task,with conducting a comparative analysis of the behavior results of three groups and block1 and block2.Results 1.three groups comparison:hit numbers of C type (64.37 ±5.29) and Ⅰ type (63.55 ±5.28) were lower than that of the normal control group(67.04 ±2.03) ; reaction time of Ⅰ type (540.33 ± 90.33) ms was longer than that of the normal control group (470.56 ± 95.39)ms; intra-individual variability(ⅡⅤ) of C type (174.24 ± 56.3)ms and Ⅰ type (201.12 ± 50.79)ms were higher than that of the normal control group(144.72 ± 37.17) ms.Commission errors of other figures after 1 of C type was higher than that of Ⅰ type; reaction time of commission errors of Ⅰ type[(701.34 ±311.54) ms] was longer than that of C type((512.57 ± 279.22)ms),and all the differences were statistically significant (P ＜ 0.05).2.Timeon-task comparison:hit numbers,omission errors and ⅡⅤ had the significantly main effect of the type of subjects (P ＜ 0.05) ; hit numbers,omission errors,reaction time and ⅡⅤ had the significantly main effect of time-on-task (P＜0.01) ; Block2 the reaction time of C type and Ⅰ type((501.82 ± 112.47)ms,559.33 ± 90.73)ms) were significantly longer than that of Block1 ((473.19 ± 106.43) ms,(523.45 ± 99.86) ms) (P ＜ 0.05),while no significant difference (P＞0.05) in the normal control group.Conclusions C type ADHD has attention deficit and impulsivity and response inhibition defects.Ⅰ type ADHD has attention deficit and information processing capacity backward.Reaction rate of ADHD is more vulnerable to the impact of time-on-task.Two subtypes of ADHD children has different modes of cognitive impairment.

Objective To investigate the behavioral problems and intelligence in children with attention deficit hyperactivity disorder (ADHD) with different degree of sensory integrative dysfunction (SID).Methods Ninety-eight children with ADHD and fifty typical developing children (TD) whose intelligence were assessed with Chinese revised wechsler intelligence scale for children(C-WISC) in this study.Parental report measures of sensory integrative dysfunction and behavioral problems were administrated using the sensory integrative rating scale of children,conners' parent symptom questionnaire (PSQ) and achenbach children behavior checklist scale (CBCL) respectively.Relationship between behavioral problems,cognitive profiles and SID were examined in in children with ADHD with different degree of SID (33 without SID,33 mild SID and 32 severe SID).Results (1) Behavioral problems:the children with ADHD with severe SID (SS) had higher scores in Conduct problem,Learinng problem,Impulsivity-hyperactivity,Hyperactivity index of the PSQ and Depression,Somatic complaint of the CBCL than the children with ADHD without SID (NS),the children with ADHD with mild SID (MS),and TD.SS group had higher scores in Withdrawn behavior,Hyperactivity index,Aggressive and Delinquent behavior in CBCL than the TD and NS groups(P＜0.05).(2) Intelligence:the SS group(98.53±l0.80) had lower Verbal Intelligence Quotient (VIQ) than the TD group(107.40± 12.03) and lower Performance Intelligence Quotient (PIQ) (94.59± 10.56) than the other groups(TD:108.96± 10.20; NS:101.88±8.15 ; MS:100.73 ± 9.52).Additionally,the SS group had lower full scale intelligence quotient (FIQ) (96.22± 10.12) than the NS(102.70±7.52) and TD group (109.18±9.95)(P＜0.05).(3) The scores of SID were negatively correlated with behavior problems (PSQ and CBCL) and positively correlated with PIQ and FIQ.Conclusion SID have negative impact on behavioral problems and cognitive function in children with ADHD.The relationship between sensory integration and cognitive function may provide a new way for the clinical intervention of children with ADHD.

Objective To observe the efficacy and side effects of combined therapy with victoria A acid,arsenic trioxide and chemotherapeutics for newly diagnosed acute promyelocytic leukemia (APL). Methods 40 cases of patients were treated with combined therapy of ATRA, As2O3 and chemotherapy. The efficacy and side effects were analysed. Results 92.5 % (37/40) achieved complete remission(CR). The CR time was 27(22-61) d by average; leukocytes≥ 10×109/L group complete remission was 72.7 % (8/11), leukocytes < 10×l09/L group complete remission was 100 % (29/29). There was a significant different (x2 =8.550, P =0.004). No severe side effects was observed except one who developed retinoic acid syndrom. Conclusion The combined regimen of ATRA and As2O3 with chemotherapy for acute promyelocytic leukemia should be the first choice management.

Objective To investigate the intelligence structure and attention properties,and to explore the relationship between them in children with attention deficit hyperactivity disorder of the predominantly inattention type (ADHD-Ⅰ),predominantly hyperactive-impulsive type (ADHD-HI) and combined type (ADHD-C).Methods Children with ADHD-Ⅰ (n=24),ADHD-HI(n=12) and ADHD-C (n=54) aged between 7-10 years were tested with Chinese Revised Wechsler Intelligence Scale for Children (C-WISC) and integrated visual and auditory continuous performance test (IVA-CPT).Comparisons of cognitive profiles of C-WISC scores between subtypes of ADHD were performed.Additionally,the relationship between attention/response control quotients and cognitive profiles was investigated.Results (1) Intelligence structure:verbal intelligence (VIQ) of ADHD-HI (110.08± 10.64) was higher than that of ADHD-C (101.13± 13.20) and ADHD-Ⅰ (94.71± 11.11).Full scale intelligence quotient (FIQ) of ADHD-HI (104.33±9.63) was higher than that of ADHD-Ⅰ (94.38± 10.48).Factor A of ADHD-HI (45.75±7.14) and ADHD-C (41.41±8.57) were higher than that of ADHD-Ⅰ (36.67±6.72).Factor C of ADHD-HI (33.42±5.42) was higher than that of ADHD-C (29.24±5.26) and ADHD-Ⅰ (29.13±5.39).(2) Attention properties:Full scale attention quotient of ADHD-C (90.26± 11.67) was lower than that of ADHD-Ⅰ (98.17 ± 18.03) and ADHD-HI (99.25± 15.58).Auditory attention quotient of ADHD-C (89.94± 14.16) was lower than that of ADHD-Ⅰ (99.00± 18.66).(3) Relationship between intelligence and attention:the Pearson correlations of the auditory attention quotient and auditory control quotient with the PIQ were 0.24 and 0.29 respectively.The correlations of the visual attention quotient with the PIQ and FIQ were 0.21 and 0.25 respectively.The correlations of the full scale attention quotient with PIQ and FIQ were 0.27 and 0.24 respectively.Each of these correlations reached the level of significance at the 5％ level.Conclusion Cognitive profile and attention properties analysis reveal that children with different subtypes of ADHD have distinct weakness in intelligence structure.The understanding of relationship between intelligence structure and attention properties in children with subtypes of ADHD is useful for ADHD diagnosis and treatment.

Objective To investigate behavior and electrophysiological manifestations of sustained attention and executive function in School-age children with tic disorder(TD).Methods Sixty-six school-aged children (36 TD and 30 control) participated in a CPT-AX task.Behavioral measures and ERP measures were collected.Results The 1.The Behavior results:there were no significant differences between the TD group and the control group in hitting number ((38.07 ± 3.04),(38.93 ± 1.48)),reaction time ((465.427 ± 97.00) ms,(500.17 ± 131.29) ms),the number of errors of omission((1.97 ± 3.02),(1.07 ± 1.48)) and the number of false errors ((1.77 ± 2.50),(1.07 ± 1.53)) (P ＞ 0.05).2.The ERP results:①Group and condition had significant main effect and interaction effect on N2 amplitude (P ＜ 0.05),while not on the latency of N2 (P ＞ 0.05).②Group had significant main effect on the amplitude and latency of P3,but main effect of Group and the interaction effect are not significant (P ＞ 0.05).③The TD group's amplitude of Nogo-N2 ((-1.39 ± 3.321) μV) were smaller than that of the control group ((-4.09 ± 2.94) μV) (P ＜ 0.05).Conclusion Children with TD performance impaired conflict monitor,while exhibit no deficits in sustained attention and response inhibition.

Objective To investigate cross-cultural differences in picture recognition memory of medical students. Methods Picture recognition memory were assessed by the classic new-old picture recognition,and behavioral results were recorded during the test. Results For new medical picture recognition, mean accuracy of Chinese medical students( 83.21 ± 8.95 )% was considerably higher than that of Indian medical students( 75.56 ±12.63)% (P＜0.05), while for old medical picture recognition, reaction time (RT) of Chinese medical students ( ( 887.57 ± 104.07 ) ms ) was longer than that of Indian medical students ( ( 840.93 ± 1 22.48 ) ms) (P＜0.05).Three way ANOVA suggested that cultural background and picture type significantly affected accuracy and RT,learning experience affected RT. In addition to picture type and learning experience, the interaction of each factors is not remarkable. Conclusion Cultural background, professional background and learning experiences have affected recognition memory. Medical students of different cultural background adopted difference strategies in picture recognition memory.

Objective To compare the event-related potential(ERP) difference waveforms between attention deficit hyperactivity disorder (ADHD) children and normal children in the conflict task,and to investigate the neural mechanism of conflict monitoring of ADHD. Methods ERPs elicited by performing the spatial SimonStroop task were recorded in 32 children with ADHD and 32 normal children. The differences of ERP and behavior dren with ADHD(0.80±0. 11 ,0.87 ±0.08) were less than normal children (0.88 ±0.07,0.93 ±0. 04)in Sireaction time of ADHD group( (773.03 ±99.34)ms) in the Siin were longer than the control group( (737.21 ±81.40)ms) ,the differences had statistic significance (P＜0. 05). 2. ERP results:the amplitude of N2 of the children with ADHD in the four conditions were smaller than the control group, the difference in Siin had statistic sigof prefrontal and anterior cingulate cortex of ADHD were weaker than the control group. Conclusions The results suggest that, due to the inadequate allocation of attention resources of the children with ADHD, they have conflict monitoring function defects compare with normal children. The function defects of conflict information processing related brain areas may be the main neural mechanism. The result of the behavior and ERP can become the reference indicator for the early diagnosis and treatment of ADHD.

Objective To investigate pathological mechanism of dysfunction of executive control in children with attention-deficit hyperactivity disorder (ADHD) ,using a new resting-state functional magnetic resonance imaging(fMRI) index, fractional amplitude of low frequency fluctuation (fALFF). Methods Thirty children of school age with ADHD and thirty gender, age and education-matched healthy controls were experienced restingstate fMRI scans. fALFF approach was used to analyze blood oxygen level-dependent fMRI(BOLD-fMRI) data in resting state. Results Compared with the normal controls,the ADHD showed decreased fALFF in the bilateral superior frontal gyrus( BA10, t=5. 40,4.11 ,Z =4.81,3.82),bilateral middle frontal gyrus( BA9,BA46, t=5.72,5.37, Z = 5.04,3.08 ), right medial frontal gyrus ( BA 10, t = 5.53, Z = 4.90 ) and left precuneus ( t = 3.81, Z =3.57). And the ADHD showed increased fALFF in the bilateral limbic lobe (BA36, t = 4.37,5.20, Z = 4.02,4.66 ), right brainstem ( t = 4.77, Z = 4.34) and bilateral cerebellum ( t = 4.65,4.83, Z = 4.24,4.38 ). Conclusion The results suggest that lower activition of frontal may be the core deficit of executive control with ADHD in resting state,and high activation in several brain regions may be related to compensatory effect.
