Objective To investigate the characteristics of electroencephalograms ( EEGs ) of patients with childhood absence epilepsy ( CAE ) .Methods EEG of 46 patients with CAE were analyzed .Results Of 46 patients,there were 44 cases (95.6%) with guided bilateral symmetry 3Hz spike-and-wave.16 cases were character-ized by multiple spike-and-wave on the 3Hz spike and slow wave;and the centrotemporal spikes was found in 1 case. Additionally,the 3Hzδactivity in occipital region has been traced in 34 cases of these 46 patients.Conclusion In general,the EEGs of CAE patients have typical characteristics ,and few of them showed atypical manifestation ,which must be verified by clinical attention .

Objective:To investigate the significance of sleep electroencephalogram (EEG) monitoring in the diagnosis and differential diagnosis of childhood epilepsy.Methods:The clinical data of 56 children with epilepsy diagnosed in The Maternal and Child Health Hospital of Huainan from February 2020 to February 2022 were retrospectively analyzed. The relationship between the positive rate of epileptiform discharge under sleep EEG monitoring and its location and sleep phase was analyzed.Results:Of the 56 children, 36 (64%) children had normal results of routine awake EEG monitoring, and 20 (36%) children had abnormal results. Among the 56 children, 9 (16%) children had normal sleep and 47 (84%) had abnormal sleep. The difference in EEG monitoring results between the awake and asleep states was statistically significant ( χ2 = 27.08, P < 0.001). Among abnormal EEG in 47 patients, paroxysmal abnormality (epileptiform discharge) was found in 44 patients and non-specific abnormality was found in 3 patients. Among the 44 children with epileptic discharges, 5 (11%) had epileptic discharges during wakefulness, 11 (25%) children had epileptic discharges during a sleepless period, and 28 (64%) had epileptic discharges during a slight sleep period. EEG epileptiform discharges occurred in the central temporal region in 9 (21%) patients, temporal region in 8 (18%) patients, parieto-occipital region in 1 (2%) patient, frontal region in 5 (11%) patients, and the frontotemporal region in 6 (14%) patients. Generalized discharges were found in 14 (32%) patients, and generalized hypsarrhythmia was found in 1 (2%) patient. Conclusion:Children with clinically highly suspected epilepsy should be reexamined by sleep EEG if the routine awake EEG, monitoring results are normal, to reduce the rates of misdiagnosis and missed diagnosis in children with epilepsy.

OBJECTIVE:To investigate clinical efficacy and safety of Miao medicine Jinyin huashi granules combined with western medicine in the treatment of chronic calculous cholecystitis(CCC). METHODS:A total of 120 CCC patients in our hospi-tal during Jan. 2014-Jan. 2016 were randomly divided into control group and observation group,with 60 cases in each group. Con-trol group was given 50％ Magnesium sulfate solution 10 mL orally before meal,tid;amoxicillin 0.5 g orally,tid+Racanisodamine tablets 10 mg,tid+Compound dantong tablets 1 slice,tid,after meal. Observation group was additionally treated with Miao medi-cine Jinyin huashi granules 15 g,tid,on the basis of control group. Both groups were treated for consecutive 4 weeks. Clinical effi-cacies,the improvement of upper abdominal pain,nausea and greasy,calculus were observed in 2 groups. The thickness of gall-bladder,serum levels of IL-2 and IL-5,mRNA and protein expression of CYP7A1 and B-UCT were compared between 2 groups before and after treatment. The occurrence of ADR was recorded in 2 groups. RESULTS:Total response rate of observation group was 96.67％,which was significantly higher than 88.33％ of control group,with statistical significance (P<0.05). One d and one week after treatment,the improvement rates of upper abdominal pain were 63.33％ and 81.67％ in observation group, which were significantly than 36.67％ and 50.00％ of control group,with statistical significance(P<0.05). There was no statisti-cal significance in the improvement rate of nausea or greasy after treatment between 2 groups(P>0.05). The stone-free rate of ob-servation group was 33.33％ and significantly higher than 11.67％ of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the thickness of gallbladder wall,serum levels of IL-2 or IL-15,mRNA and pro-tein expression of CYP7A1 or B-UCT between 2 groups(P>0.05). After treatment,the thickness of gallbladder wall,serum lev-els of IL-2 and IL-15 were all decreased significantly in 2 groups,while mRNA and protein expression of CYP7A1 and B-UCT were increased significantly;observation group was significantly better than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Miao medicine Jinyin huashi granules combined with western medicine show significant therapeutic efficacy for CCC,can effectively improve right upper quadrant pain,nausea and greasy,decrease serum levels of IL-2 and IL-5 and up-regulate mRNA and protein expression of CYP7A1 and B-UCT with good safety.
