ObjectiveTo investigate the clinical characteristics of epileptics with pregnancy and then provide reference for standardized management of epileptics with pregnancy. MethodsFrom June 2012 to June 2021, epileptics with pregnancy who delivered in Jinan Central Hospital were selected as the research subjects. The clinical data such as the application of Antiseizure medications (ASMs) during pregnancy, seizure frequency, pregnancy outcomes, delivery ways, offspring feeding ways and the incidence of complications were investigated and analyzed. ResultsAmong 36 epileptics with pregnancy, 20 cases (55.56%) were treated with ASMs alone, 5 cases (13.88%) were treated with combined medication, and 11 cases (30.56%) were treated without ASMs during pregnancy. 15 cases (41.67%) adhered to systematic application of ASMs, 17 cases (47.22%) did not adhere to systematic application of ASMs, and 4 cases (11.11%) had unknown medication history. The frequency of seizures increased in 5 cases, decreased in 7 cases and unchanged in 24 cases during pregnancy. Pregnancy outcomes: full-term delivery in 33 cases (91.67%), preterm delivery in 1 case (2.78%) and abortion in 2 cases (5.56%). Delivery mode: cesarean section in 31 cases (91.18%), vaginal delivery in 3 cases (8.82%). After delivery, 4 cases (11.76%) were fed with milk powder and 30 cases (88.24%) were breast-fed. Complications: There were 6 cases complicated with anemia (16.67%), 5 cases complicated with gestational hypertension (13.89%), 3 cases complicated with gestational diabetes (8.33%), 4 cases complicated with premature rupture of membranes (11.11%), 2 cases complicated with fetal growth restriction (5.56%), 2 cases complicated with oligohydramnios (5.56%), 3 cases complicated with fetal distress (8.33%) and 3 cases complicated with neonatal asphyxia (8.33%). ConclusionsThe proportion of epileptics with pregnancy who were systematically treated with ASMs was low and the seizures were poorly controlled. There is a lack of standardized management for such patients in clinical practice.
It is very important for epilepsy treatment to distinguish epileptic seizure and non-seizure. In this study, an automatic seizure detection algorithm based on dual density dual tree complex wavelet transform (DD-DT CWT) for intracranial electroencephalogram (iEEG) was proposed. The experimental data were collected from 15 719 competition data set up by the National Institutes of Health (NINDS) in Kaggle. The processed database consisted of 55 023 seizure epochs and 501 990 non-seizure epochs. Each epoch was 1 second long and contained 174 sampling points. Firstly, the signal was resampled. Then, DD-DT CWT was used for EEG signal processing. Four kinds of features include wavelet entropy, variance, energy and mean value were extracted from the signal. Finally, these features were sent to least squares-support vector machine (LS-SVM) for learning and classification. The appropriate decomposition level was selected by comparing the experimental results under different wavelet decomposition levels. The experimental results showed that the features selected in this paper were different between seizure and non-seizure. Among the eight patients, the average accuracy of three-level decomposition classification was 91.98%, the sensitivity was 90.15%, and the specificity was 93.81%. The work of this paper shows that our algorithm has excellent performance in the two classification of EEG signals of epileptic patients, and can detect the seizure period automatically and efficiently.
Objective To explore the damage, damage model and influence factors of the empathy ability on patients with epilepsy by the Chinese version of interpersonal reaction index scale (IRI-C). Methods Eighty-eight non-symptomatic epilepsy patients who were from the First Affiliated Hospital of Dalian Medical University and 100 healthy controls were included in the study from March 2015 to January 2016. Patients with serious cognitive impairment and severe anxiety or depression were ruled out through neural psychology background screening (Montreal Cognitive Assessment, Hamilton anxiety and depression scale) due to their influence on empathy scores. Thereafter the empathy ability was compared between epilepsy patients and healthy controls using the IRI-C, and the effect of seizure type on empathy ability was analyzed. According to the epileptic seizure types of generalized tonic-clonic seizure (GTCS), patients were divided into 3 groups: non-GTCS group (simple or complex partial seizure, n=17), pure GTCS group (only primary GTCS attack, n=23) and SGS group (partial onset secondary GTCS,n=48). The control group included 100 healthy participants. In order to ensure the balance of sample size, 30 samples are randomly selected from SGS and control groups respectively for statistical analysis. Then patients were divided in two groups according to whether he/she has complex partial seizure (CPS), and 30 patients in each group. Statistical analysis was performed using SPSS18.0 software package. Results ① The total IRI-C Empathy scores, Cognitive empathy (CE) and two factors of the patients in epilepsy group were lower than those in control group (P<0.05), while there was no statistical difference in Emotional Empathy (EE) and two factors between groups (P>0.05). ②ANOVA showed the points of CE (include two factors) and total scores of empathy mean different between the four groups (P<0.05), and EE (include two factors) scores were no statistically significant differences between the four groups (P>0.05). The CE scores were differences between the GTCS group, pure GTCS group and SGS group. The scores of the perspective-taking was statistically significant differences (P<0.05) between the pure GTCS group and the SGS group. The scores of perspective-taking of SGS group were lower than the other groups (P<0.05) . In other words, the scores of the perspective-taking of SGS group were lower than those of the other three groups, and the CE scores were lower than the GTCS group and the control group. ③ The opinion selection, imagination, CE and total empathy score of CPS group were all worse than that of non-CPS group (P<0.05). Conclusions The empathy ability of epilepsy patientswere impaired in CE, but reserved in EE Epileptic subtype CPS and GTCS were risk factors of the decline in empathy ability in epilepsy patients.
Objective To investigate the effects of a mixed bacterial lysate (OM-85 BV) on lung function and serum IgE in asthmatic mice under acute attack, and to explore the therapeutic effect of OM-85 BV on acute attack and the application value of OM-85 BV in non-acute attack. Methods A total of 30 SPF Kunming mice aged 4 to 6 weeks were randomly divided into 3 groups, namely a blank control group (Group A), an asthma model group (Group B), and an OM-85 BV intervention group (Group C). The mice in groups B and C were sensitized by intraperitoneal injection of ovalbumin on day 1, 8 and 15, respectively. From day 22, the asthma model was stimulated by inhalation of 5% ovalbumin every day for 30 min for 5 consecutive days. The mice in group C were treated with OM-85 BV dissolved in normal saline from day 1, and each mouse was gavaged continuously for 10 days. The intraperitoneal injection, intragastric administration and aerosol inhalation reagent of mice in group A were all replaced by normal saline, while the intragastric administration of mice in group B was replaced by normal saline. One hour after the last stimulation, the mice were anesthetized, their lung function was measured, blood was collected from the eyeballs and then they were sacrificed, and the blood was centrifuged and the serum was separated and stored. Hematoxylin and eosin staining was used for pathological examination. Serum IgE was determined by enzyme-linked immunosorbent assay. Results Compared with group A, forced vital capacity in 0.15 second (FEV0.15), FEV0.15/forced vital capacity (FVC) and peak expiratory flow (PEF) of mice in group B were significantly decreased. The lung function of group C was improved compared with group B. In group B, the pathological manifestations were dysplasia and collapse of bronchial epithelium, infiltration of inflammatory cells, mainly lymphocytes and eosinophils, a small amount of mucus and shed epithelial cells in the tracheal lumen, and significant thickening of airway wall. The asthma mouse model was well established. The pathological manifestations of airway in group C were less severe than those in group B, the thickness of airway wall was reduced, and the inflammatory cells were also significantly reduced. The serum IgE concentration in groups B and C increased, and the IgE level in group C decreased significantly compared with group B. The differences were statistically significant (all P<0.05). Conclusions Exogenous administration of OM-85 BV in asthmatic mice can effectively reduce the concentration of serum IgE, alleviate airway inflammation, reduce eosinophil infiltration, and improve the pulmonary function performance of asthmatic mice during acute attack, showing that FEV0.15/FVC, FEV0.15 and PEF indicators are significantly improved. OM-85 BV can alleviate the symptoms of bronchial asthma in the acute attack of mice, improve the physiological function of the lung during the acute attack, inhibit airway inflammation, and have certain application value in the stable asthma control.
