Epilepsy is a common neurological disease, and studies have shown that some epilepsy patients are combined with cognitive impairment. In clinical practice, it has been found that, in addition to the seizure itself, anti-seizure medications can also have a corresponding impact on the cognitive function of epilepsy patients. However, the effects of some drugs on the cognitive function of epilepsy patients are still inconclusive, and the mechanism of their influence on cognitive function in epilepsy patients is not elucidated. In recent years, some studies followed up the cognitive function of patients receiving anti-seizure medications therapy, and put forward guidance. This article focused on the research of commonly used drugs on cognitive function, the possible mechanism of drugs affecting cognitive function, the rational use of drugs in different groups of people and the prevention strategies of related cognitive dysfunction, hoping to improve emphasis on cognitive function in epilepsy patients and guide clinical practice.

Objective:To investigate the clinical characteristics and gene sequencing results of NDM, so as to provide evidence for clinical diagnosis and treatment .Methods:Clinical data of 1 child diagnosed with NDM in Hebei People's Hospital in January 2021 were retrospectively analyzed, and DNA gene sequencing was performed in the peripheral blood of the child, and relevant literatures were reviewed.Results:The child was born with a weight of 2.2kg. On the second day after birth, blood glucose significantly increased and insulin and C-peptide levels decreased. After 14 days of insulin treatment, hyperglycemia was still present, which was consistent with the diagnosis of NDM. Genetic testing indicated that there were missense mutations of newborn compound heterozygote in ABCC8 gene: c. 752G > A (p.G251E), c. 772A > G (p.R258G). The mutation of c. 772A > G in ABCC8 gene had not been reported before, and sulfonylureas were effective for the treatment of the child.Conclusion:NDM is a rare monogenic genetic disease with a lack of specificity in clinical manifestations. For children diagnosed or suspected of NDM, genetic testing should be actively carried out, which is of great significance for clinical diagnosis, treatment and prognosis.

Objective:To investigate the mediating and moderating effects of resilience on frailty and depression in the community-dwelling old adults.Methods:Totally 871 community-dwelling old adults chosen from different communities were investigated by the geriatric depression scale, Tilburg frailty indicator and 10-item Connor-Davidson resilience scale.SPSS 22.0 and AMOS 24.0 were used for data analysis, including descriptive analysis, correlation analysis, structural equation modeling and hierarchical regression analysis.Results:(1)The score of frailty (3.72±2.89)was positively correlated with the score of depression (2.63±2.57, r=0.16-0.58, P<0.01). The score of resilience(28.24±6.80) was negatively correlated with the score of frailty and depression ( r=-0.10~-0.49, both P<0.01), and frailty predicted 35% of the total variation of depression in the elderly.(2)The mediating effect of resilience was significant and the indirect effect was 0.10, accounting for 12.66% of the total variance.(3) Resilience moderated the relationship between frailty and depression ( β=-0.12, t=-4.11, R2=0.41, P<0.001). The frailty of old adults with lower resilience played a stronger predictive role in depression (simple slope=0.50, t=14.73, R2=0.01, P<0.001). Conclusion:There is a close relationship between frailty and depression in the community-dwelling older adults, and resilience plays both mediating and moderating role in the relationship.

Objective To investigate the feasibility and safety of using vasodilators in the treatment of neonates with patent ductus arteriosus (PDA) accompanied by acute heart failure and pulmonary edema. Methods The clinical data of a case of neonatal PDA accompanied by severe cardiac insufficiency and pulmonary edema in Department of Intensive Care Unit (ICU) of Hebei General Hospital, and the neonate's hemodynamic characteristics and the efficacy and adverse reactions of phentolamine, a vasodilator, in the treatment of PDA were retrospectively analyzed. Results In this neonate, on the 8th day after birth and the improvement of pulmonary hyaline membrane disease, the respiratory distress occurred again, which was related to the severe cardiac dysfunction caused by the opening of PDA. Phentolamine was given on the basis of routine treatment to reduce systemic circulatory resistance. Two hours later, the respiratory distress was relieved significantly, that was presumably related to the decline of the left to right shunt volume through the PDA. There were no adverse reactions such as blood pressure reduction and coronary insufficiency. Conclusion Neonatal PDA is easily to be complicated with severe cardiac insufficiency, and vasodilators can reduce systemic circulatory resistance, reduce left to right shunt volume through the ductus arteriosus, and reverse the acute cardiac insufficiency and pulmonary edema, the therapeutic effect of vasodilators is remarkable, safe and reliable in neonatal PDA.

Isolation rearing (IR) enhances aggressive behavior, and the central serotonin (5-hydroxytryptamine, 5-HT) system has been linked to IR-induced aggression. However, whether the alteration of central serotonin is the cause or consequence of enhanced aggression is still unknown. In the present study, using mice deficient in central serotonin Tph2 and Lmx1b, we examined the association between central serotonin and aggression with or without social isolation. We demonstrated that central serotonergic neurons are critical for the enhanced aggression after IR. 5-HT depletion in wild-type mice increased aggression. On the other hand, application of 5-HT in Lmx1b mice inhibited the enhancement of aggression under social isolation conditions. Dopamine was downregulated in Lmx1b mice. Similar to 5-HT, L-DOPA decreased aggression in Lmx1b mice. Our results link the serotoninergic system directly to aggression and this may have clinical implications for aggression-related human conditions.

PURPOSE: Long non-coding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated as an oncogene in the development and progression of osteosarcoma. This study aims to explore the mechanism of NEAT1 in osteosarcoma. MATERIALS AND METHODS: Expressions of NEAT1 and miR-194 in osteosarcoma tissues and cells were detected by quantitative real-time PCR. The effects of NEAT1 knockdown or miR-194 overexpression on cell proliferation, invasion, and apoptosis were determined by 3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide (MTT) assay, transwell invasive assay, and flow cytometry analysis, respectively. Luciferase reporter assay was performed to observe the possible interaction between NEAT1 and miR-194. RESULTS: NEAT1 was upregulated and miR-194 was downregulated in osteosarcoma tissues and cells. Knockdown of NEAT1 or overexpression of miR-194 suppressed proliferation and invasion and induced apoptosis of osteosarcoma cells in vitro. Luciferase reporter assay validated that NEAT1 could interact with miR-194 and negatively modulated its expression. Furthermore, inhibition of miR-194 reversed the suppression of proliferation and invasion and the promotion of apoptosis induced by NEAT1 depletion in osteosarcoma cells. CONCLUSION: Knockdown of NEAT1 suppressed proliferation and invasion and induced apoptosis in osteosarcoma cells by inhibiting miR-194 expression.
