ABSTRACT
Objective:To explore the brain electrical activity and its correlation with polysomnography monitoring parameters in children with obstructive sleep apnea syndrome (OSAS) and primary snoring.Methods:It was a prospective observational study involving children aged 6-12 years who presented to the Sleep Center of Beijing Children′s Hospital, Capital Medical University for polysomnography monitoring due to snoring at sleep from July 1 to December 31, 2019.Clinical data, polysomnography monitoring and 6-min measurement of brain electrical activity were collected from all the subjects.According to the results of polysomnography monitoring, the subjects were divided into the primary snoring group and the OSAS group at varying degrees.Based on the electroencephalogram (EEG) wavelet analysis, the brain injury index obtained by EEG synchronization and complexity analysis was used to reflect the changes of brain electrical activity in children in the resting state.Rank sum test was used to test the differences in brain injury index and the percentage of each frequency band of brainwave.Multivariate linear regression method was used to analyze risk factors for EEG activity.Results:A total of 149 children were recruited, including 110 males and 39 females.There was no significant difference in the proportions of α, θ, β and δ waves among OSAS children at varying degrees(all P>0.05). The brain injury index of the primary snoring group, mild OSAS group, moderate OSAS group and severe OSAS group was 0 (0, 3), 14 (9, 16), 26 (24, 28), and 34(30, 44), respectively.There were statistically significant differences in the brain injury index among groups ( H=129.70, P<0.01). The brain injury index gradually increased from the primary snoring group to the severe OSAS group.Multivariate linear regression analysis showed that the obstructive apnea hypopnea index (OAHI), mean oxygen saturation and minimum oxygen saturation were independently correlated with the brain injury index (all P<0.05). Conclusions:There were no significant differences in the ratios of α, θ, β and δ waves among OSAS children at varying degrees, while the EEG complexity and synchronicity varied a lot.With the increase of OAHI, the brain injury index gradually increased.The brain injury index was independently correlated with OAHI, mean oxygen saturation and minimum oxygen saturation.
ABSTRACT
Objective:To understand the clinical features and risk factors of the first seizures in children with febrile seizures, to guide clinicians to take appropriate intervention measures for children with risk factors, and to reduce the incidence of febrile seizures.Methods:A total of 616 children with first-onset febrile seizures admitted in our hospital from August 2016 to August 2018 were enrolled in this study.The clinical characteristics and risk factors of first-onset seizures were retrospectively analyzed.And 601 children with fever but no seizures were randomly selected as the control group.Results:There were 616 children with febrile seizures, including 344 males and 272 females, 584 Hans and 32 Mongolian.A total of 126 cases (20.5%) were under 1 year old, 405 cases (65.8%) were 1-3 years old, and 85 cases(13.7%) were over 3 years old.The upper third of the episodes were acute upper respiratory tract infections[53.6%(330/616)], herpetic angina[25.9% (160/616)], and infant acute rash[10.5%(65/616)]. There were 570 cases(92.5%) with seizures at 38.0 ℃ and above, 16 cases(2.6%)had fever after seizures.A total of 534 cases(86.7%) had seizures within 24 hours of fever, and 608 cases(98.7%) presented with a generalized seizures.The duration of seizures was less than 5 min in 548 cases (89.0%), 5-14 min in 48 cases (7.8%), 15-29 min in 16 cases (2.6%) and more than 30 min in 4 cases (0.4%). Of the 572 patients (92.9%), only one seizure occurred in a single heat stroke.In the clinical type, simple febrile seizures accounted for 88.3%(544/616), complex febrile seizures accounted for 11.0%(68/616), and seizures persisted in 0.7%(4/616). Risk factors analysis showed that age, low sodium, low iron and low zinc, cesarean section, abnormal birth history, vaccine exposure history one week before convulsion, and family history of febrile seizures were statistically different between the febrile seizure group and the control group( P<0.05). Logistic regression analysis found that the age of first febrile seizures, low iron, cesarean section, low sodium and family history of febrile seizures were the independent risk factors for the first episode of febrile seizures ( P<0.05). Conclusion:The first episode of febrile seizures are more common in infants and young children under 3 years old.It is mainly caused by simple febrile seizures.The temperature of seizures is high and it is easy to occur within 24 hours after fever.Viral infection is the most common cause.The risk factors for the first episode of febrile seizures are episode age, low iron, cesarean section, low sodium and family history of febrile seizures.Taking appropriate interventions for risk factors can reduce the incidence of febrile seizures.

ABSTRACT
Objective To investigate skin manifestations and comorbidities of chronic arsenicosis due to conta?minated drinking water, and to explore their possible risk factors. Methods Data about demographic characteristics, skin manifestations and comorbidities were collected from 95 patients with chronic arsenicosis due to contaminated drinking water in Inner Mongolia, and retrospectively analyzed. A logistic regression model was established to analyze associations of skin manifestations and comorbidities with patients′ gender, age, age at onset of drinking of arsenic?contaminated water, arsenic concentrations in water and duration of arsenic exposure. Results Among the 95 patients, 77 had hyperpigmentation, 75 hypopigmentation, 93 palmoplantar keratoderma, 27 skin cancer, and 8 multiple skin cancer. Five patients were complicated by tuberculosis, 15 by hypertension, 2 by rheumatoid arthritis, 4 by cerebral infarction, 7 by coronary heart diseases, 3 by internal malignancy, 6 by hepatic cirrhosis and 2 by anemia. Logistic regression analysis revealed a significant correlation between hyperpigmentation and arsenic concentrations in water(OR=0.32, 95%CI=0.10-0.98;ORadjusted=0.27, 95%CI=0.08-0.90), between occurrence of hepatic cirrhosis and arsenic concentrations in water (OR=24.67, 95%CI=2.69-226.57;ORadjusted=22.51, 95%CI=2.38-213.11), and between occurrence of coronary heart diseases and duration of arsenic exposure(OR=6.41, 95%CI=1.09-37.88;ORadjusted=8.55, 95%CI=1.21-60.41). Conclusions There is a high incidence of aberrant pigment metabolism, palmoplantar keratoderma and skin cancer in patients with chronic arsenicosis due to contaminated drinking water. Different arsenic concentrations in water and duration of arsenic exposure seem to have different influences on the human body.

ABSTRACT
OBJECTIVE To identify differentially expressed microRNA (miRNA) in peripheral blood mononuclear cells (PBMCs) of anxiety patients and predict their target genes and function by bioinformatics analysis. METHODS The miRNA expression profiles were determined using an Affymetrix array. To validate the results, real-time quantitative polymerase chain reaction (qRT-PCR) analysis in a larger cohort was employed. The targets of the differentially expressed miRNAs were predicted by Target Scan, miRBD, and DIANA-microT-CDS, and the results were analyzed by gene ontology (GO) and KEGG pathway analysis using FunNet. RESULTS MicroRNA microarray chip analysis has identified 7 miRNAs were detected with significant changes in expression in PBMCs of anxiety patients. qRT-PCR analysis has confirmed that the expression levels of 5 miRNAs (has-miR-4484, has-miR-4505, has-miR-4674, has-miR-501-3p and has-miR-663) were up-regulated. Intersecting the genes by Target Scan, miRBD, and DIANA-microT-CDS has predicted 195 targets. GO analysis showed that biological processes regulated by the predicted target genes have included diverse terms. Some terms, e.g., nervous system development, nerve growth factor receptor signaling pathway, neuron migration, dendrite development, regulation of neuron projection development, midbrain development, regulation of excitatory postsynaptic membrane potential, gliogenesis, dendrite morphogenesis, etc. have direct relationship with the central nervous system and brain functions. Pathway analysis showed that a significant enrichment in several pathways related to neuronal brain functions such as glutamatergic synapse, axon guidance, calcium signaling pathway, MAPK signaling pathway, GnRH signaling pathway, Wnt signaling pathway, gap junction, long-term potentiation and VEGF signaling pathway, etc. Among the five microRNAs, has-miR-4484, has-miR-4505, has-miR-4674 and has-miR-501-3p may have more important regulatory functions. CONCLUSION Five miRNAs (has-miR-4484, has-miR-4505, has-miR-4674, has-miR-501-3p and has-miR-663) are up-regulated in PBMCs of anxiety patients and may be closely involved in the pathogenesis of anxiety disorder.

Objective To investigate the correlation factors for hot flashes in climacteric women so as to improve their quality of life. Methods A questionnaire was distributed among 792 climacteric women. The questionnaire items included general information, characteristics of menstruation, reproduction history, information of hot flashes, lifestyle and sexual life. Weight, height, blood pressure, waist and hip circumferences were measured. Logistic regression analysis was made to find out the correlation factors for hot flashes. Results Univariate logistic regression analysis showed that age, education, income, present characteristics of menstruation, dietary habit, soy products intake, physical exercise, satisfaction of sexual life, body mass index (BMI) and systolic blood pressure were significantly associated with hot flashes. Multivariate logistic regression analysis revealed that irregular menstruation or menopause, frequent exercise and higher systolic blood pressure were risk factors for hot flashes in climacteric women. However, higher education, soy products intake and satisfaction of sexual life were protection factors. Conclusion Guiding climacteric women to take moderate physical exercise, knowing more about climacterium, consuming more soy products and controlling diastolic blood pressure are likely to decrease the incidence of hot flashes.
ABSTRACT
Objective To study the effect of the levels of serum gonadal hormone and plasma calcitonin gene-related peptide(CGRP) on the hot flushes symptom of perimenopausal women. Methods 65 perimenopausal women (35 with hot flushes and 30 without hot flushes) and 25 healthy fertile women were enrolled. The subjects were analyzed for serum estradiol (E2), follicle-stimulating hormone (FSH) ,luteinizing hormone (LH) and plasma calcitonin gene-related peptide (CGRP). Results. ① There were no significant differences of the E2 levels between the perimenopausal women with and without hot flushes (P>0.05). The levels of FSH and LH were significantly higher in the women with hot flushes than women without hot flushes and fertile women(P<0.05),② The levels of plasma CGRP were significantly higher in the women with hot flushes than women without hot flushes (P<0.05), and significantly lower than fertile women,③The levels of plasma CGRP were significantly higher in severe hot flu-shes group than that in the mild hot flushes group and moderate hot flushes group(P<0.05), the severity of hot flu-shes was positively related to the level of plasma CGRP(rs=0.823, P<0.01), but there was no relationship be-tween serum E2 and the severity of hot flushes (P>0.05). Conclusion The occurrence of perimenopansal hot flu-shes might be closely related to the decline and fluctuation of serum E2,increase of FSH and LH and the concentra-tion variety of plasma CGRP.
