ABSTRACT
Objective:To analyze the characteristics of childhood absence epilepsy (CAE) attentional network damage.Methods:A total of 40 CAE children and 40 healthy children who received physical examination in the Provincial Children's Hospital Affiliated to Anhui Medical University from November 2017 to September 2018 were selected for online examination by using the improved attention netwoks test (ANT).Results:The accuracy rate of attention network examination in CAE children [(94.98±2.20)%] was lower than that in the healthy control group [(97.58±1.52)%], and the difference was statistically significant ( t=6.151, P<0.001). The total mean response time of the CAE group [(1 076.9 5±190.32)ms] was significantly longer than that of the control group [(863.85±200.00)ms], and the difference was statistically significant ( t=4.882, P<0.001). The alertness network efficiency in the CAE group [(43.18±48.98)ms] was significantly lower than that in the control group [(66.18±37.37)ms], the difference was statistically significant ( t=2.361, P<0.05). The executive control network efficiency in the CAE group[(103.65±58.72)ms] was significantly lower than that in the control group [(72.28±42.56)ms], and the difference was statistically significant ( t=2.736, P<0.05). The directional network efficiency of the CAE group[(26.73±45.10)ms] was lower than that of the control group[(29.45±27.15)ms], but the difference was not statistically significant ( t=0.327, P>0.05). Age of onset was a relatively independent risk factor affecting the total mean response time of ANT in children. Conclusion:This study has proved that children with CAE have damage to attention network, and their age of onset is a clinically relevant risk factor for the level of attention network in them.
ABSTRACT
Objective To investigate the theory of mind ( TOM) and eye basic emotion recognition in benign epilepsy children with centrotemporal spikes( BECT) . Methods Totally 51 BECT patients( BECT group) and 51 healthy controls( control group) were studied by Yoni task and Eye Basic Emotion Discrimi-nation Task (EBEDT). Results ①Compared with healthy controls,BECT got significantly lower score ((54. 02±6. 03) vs (58. 04±5. 41),F(1,100)=10. 34,P<0. 05))in Yoni task,especially in affective(hot) TOM .②There was no significant difference between the BECT group(M(P25,P75):103(96,108)) and the control group(M(P25,P75):105(96,110))in the total score of Eye Basic Emotion Discrimination Task(Z=-1. 37,P>0. 05),but got significantly lower score in recognizing sadness(M(P25,P75):16(14,17) vs 18 (15,19),Z=-3. 05,P<0. 05)and fear(M(P25,P75):15(14,17) vs 16(16,18),Z=-2. 21,P<0. 05).③Pearson or Spearman correlation analysis showed that there was no significant correlation between the total score of TOM and the age,age of onset, education,seizure total number,MMSE,the Digital Span test, the verbal fluency test and eye basic emotion recognition ( r=-0. 257-0. 908,all P>0. 05) . Conclusion BECT children have impairments in sadness and fear emotion recognition and TOM aspects.
ABSTRACT
Objective To investigate the ability of decision-making under risk condition in benign epilepsy children with centrotemporal spikes (BECT).Method Seventy-eight BECT patients and seventyfive healthycontrols were studied by Iowa Gambling Task (IGT) with inexplicit probability and Game of Dice Test (GDT) with explicit probability.Results (1) There was a significant difference in IGT task scores between the two group (t=-2.56,P＜0.05).The total number of advantageous choices in IGT were lower in BECT group (49.35±5.38) than that in healthy control group (52.24±6.23).BECT group (-1.41 ± 10.60) performed worse on task than healthy control group (4.43±11.88),and the difference was statistically significant (t=-3.21,P＜0.05).The control group scored higher on Blockl,Block4 and Block5 than that of BECT group (P＜0.05).(2) There was no significant difference between the BECT group (4.42±7.74) and the control group(5.49±6.81) in the GDT test scores (t=-0.91,P=0.37).(3) Pearson correlation analysis showed that there was no significant correlation between the age,age of onset,education,seizure frequency and onset duration and the score of IGT and GDT (r =-0.091-0.274,all P ＞ 0.05).Conclusion There is no significant decision-making disability in children with BECT under the condition of certain risk probability,while there is significant impairment under the condition of uncertain risk probability.The decision-making disability may be associated with impaired frontal lobe function.
ABSTRACT
Objective To optimize novel triazole antifungal compounds synthesis of key intermediates.Methods The or-thogonal experimental design is used,emphasizing on four factors including the reaction temperature,the weight ratio of mate-rial,reaction time and solvent on the yield.Results The effect of reaction temperature on the reaction yield is the most signifi-cant,followed by reaction time ;the weight ratio of material and solvent on the yield impact is not obvious.Conclusion The new technology has several advantages and yields up to about 50%,less reactive impurities,easy post processing.
ABSTRACT
Objective To investigate the characteristics of attention networks impairment in benign epilepsy children with centrotemporal spikes.Methods The attention network test was performed in benign epilepsy children with centrotemporal spikes (n =75) and normal controls (n =75) on the efficiency of three anatomically defined attention networks:alerting,orienting,and execrtive control.Results The correct rate of attention network test was significantly lower in benign epilepsy children with centrotemporal spikes (95.77％ ± 5.63％) than that in normal controls (98.55％ ± 1.80％ ; t =4.063,P ＜ 0.05).The total average response time was significantly longer in benign epilepsy children with centrotemporal spikes ((946.87 ± 199.82) ms) than that in normal controls ((729.00 ± 146.75) ms ; t =-7.611,P ＜ 0.05).The orienting network effect (29 (12,56)ms) was lower in benign epilepsy children with centrotemporal spikes than in normal controls (51 (21,78) ms; Z =-2.771,P =0.006).The executive control network effect was higher in benign epilepsy children with centrotemporal spikes (80 (50,105) ms) than in normal controls (57 (25,88) ms; Z =-2.146,P =0.032).However,the difference in alerting network effects between the two groups was not statistically significant (P ＞ 0.05).Logistic regression analysis showed that the age on onset of the disease was an independent risk factor for the correct rate of attention network test and the total average response time (OR =1.830,95％ CI 1.193-2.807,P =0.006 ; OR =1.635,95％ CI 1.176-2.275,P =0.003).Conclusions The benign epilepsy children with centrotemporal spikes have impairment of attention networks.The age on onset of the disease has a significant impact on the attention of children with rolandic epilepsy.
ABSTRACT
Objective To evaluate the effect of problem-based learning (PBL)versus tradi-tional methods in medical statistics. Methods Computer retrieval was conducted to search for con-trolled studies comparing PBL and traditional methods. The quality of included studies was critically evaluated and data were analyzed by using the Cochrane Collaboration's RevMan 5.0 software. Results A total of 21 articles were retrieved,but only 7 were included. The results of Meta analysis showed that there was no significant difference between PBL and traditional methods in both the passing rate of student's score (RR=1.09,95%CI=0.98-1.23,P=0.12>0.05)and the exact score (WMD=0.30, 95%CI=-0.06 -0.67,P=0.10>0.05). Conclusion PBL showed no better learning results in medical statistics compared with traditional methods.
