ObjectivesUsing systematic literature review to analyze the effects of levetiracetam (LEV) on neonatal safety during early pregnancy.MethodsThe scope of the literature must be English literature, published from 1997 to 2018. Meta-analysis was performed by random effects models.ResultsSeven literatures were included. A total of 672 cases exposed to LEV in treatment group and 772 234 cases in control groups were selected for meta-analysis. There was no significant difference in neonatal malignancy between treatment group and control group［OR=1.05, 95% CI (0.54, 2.02), P=0.37］. Further, we evaluated the effect of LEV monotherapy and polytherapy on neonatal safety, a total of 464 monotherapy cases and 632 polytherapy cases respectively were selected for meta-analysis. The results showed that there was no significant difference between these two therapies in neonatal malignancy ［OR=0.54, 95% CI(0.31, 0.96), P=0.32］.ConclusionsAs the papers we included, levetiracetam in the treatment of epilepsy during pregnancy is relatively safe for newborn.
The aim of this study is to explore the effects of continuous theta-burst transcranial magnetic stimulation (cTBS) on functional brain network in emotion processing. Before and after the intervention of cTBS over left dorsolateral prefrontal cortex (DLPFC) of ten participants who were asked to perform the emotion gender recognition task, we recorded their scalp electroencephalograms (EEG). Then we used the phase synchronization of EEG to measure the connectivity between two nodes. We then calculated the network efficiency to describe the efficiency of information transmission in brain regions. Our research showed that after the intervention of cTBS and the stimulation of the emotion face picture, there was an obvious enhancement in the event-related spectral perturbation after stimuli onset in beta band in 100–300 ms. Under the stimulation of different emotion picture, the values of global phase synchronization for negative and neutral stimuli were enhanced compared to positive ones. And the increased small-worldness was found in emotional processing. In summary, based on the effect of activity change in the left DLPFC on emotion processing brain network, the emotional processing mechanism of brain networks were preliminary explored and it provided the reference for the research of emotion processing brain network in the future.
目的 利用磁共振彌散張量成像技術（DTI）對右側難治性顳葉癲癇（TLE）患者術前及術后腦白質各向異性分數（FA）進行縱向隨訪研究，并對其與病程等臨床癥狀之間的相關性進行分析，探討右側TLE患者的腦白質FA變化模式。 方法 2008年7月－2009年8月納入10例右側難治性TLE患者。對每個受試者采用GE 3.0 T磁共振及8通道頭線圈掃描，所有DTI圖像通過單次回波平面成像序列采集。采用基于體素分析的SPM8軟件對受試患者術前術后FA圖進行配對t檢驗，觀察難治性TLE患者腦白質變化模式。采用Pearson相關計算FA變化幅度與病程等臨床癥狀之間的相關性，經比較校正后P值＜0.05的區域為有統計學意義的區域。 結果 右側TLE患者FA值降低的區域包括左側顳下回、雙側額中回及左側殼核、右側楔葉。FA升高的區域包括左側海馬旁回、左側顳葉、右側額下回和左側中央旁小葉。相關分析發現，右側TLE患者右側額下回FA變化值與發病年齡呈負相關，左側顳下回FA變化值與術后隨訪間隔時間呈負相關。 結論 右側難治性TLE患者手術治療后大腦白質變化不僅局限于顳葉，還涉及顳葉外結構。
