ObjectiveTo explore the related risk factors of epilepsy after traumatic skull defect repair.MethodsThe clinical data of 72 cases patients underwent cranial three-dimensional titanium mesh repair in Neurosurgery Department of Sichuan Baoshihua Hospital from February 2010 to December 2017 were collected and followed up for 6 months, retrospectively analysed the causes and operation problems of secondary epilepsy after repair.Results21 casese (29.2%) among the 72 cases patients underwent cranioplasty were found with secondary epilepsy. Univariate analysis showed that the rate of secondary epilepsy in patients with softening lesion of gray matter, no formal antiepileptic treatment after the first operation, suspension of dural during operation and repair time of the trauma >6 months was significantly higher than that in patients without secondary epilepsy (P<0.05). Multivariate Logistic regression was used to correct the results, showing that softening lesion in the gray matter [OR=8.425, 95% CI (2.541, 27.934), P<0.001)], no formal antiepileptic treatment after the first operation [OR=0.160, 95% CI (0.050, 0.518), P=0.002], intra-operative suspended dural [OR=13.306; 95% CI (3.769, 46.976), P<0.001] and repair time of trauma >6 months [OR=6.205, 95% CI (1.705, 22.583], P=0.006] were independent risk factors of secondary epilepsy.ConclusionAfter decompression of bone flap, regular antiepileptic therapy, shortening repair time, and proper peroperative management can reduce the incidence of postoperative epilepsy.
【摘要】 目的 探討難治性癲癇不同類型手術的預后與病程長短有無相關關系。 方法 回顧性分析2005年1月-2009年12月在四川大學華西醫院神經外科進行難治性癲癇手術的143例患者，根據Engel分級對預后進行評估，分別分析各類型手術不同病程時間之間的預后差異以及相關關系。 結果 不同病程組顳葉手術和顳葉合并顳葉外手術的預后差異無統計學意義（Pgt;0.05），兩者之間無相關關系；顳葉外手術的預后在不同病程組間差異有統計學意義（Plt;0.05），兩者之間呈負相關。 結論 顳葉外癲癇手術的預后與病程存在相關關系；病程越短，預后越好。【Abstract】 Objective To discuss the relationship between prognosis of different intractable epilepsy surgeries and the disease course. Methods A total of 143 patients who had undergone surgeries for intractable epilepsy in the Neurosurgery Department of West China Hospital of Sichuan University from 2005 to 2009 were enrolled, and the prognosis with different disease course were assessed based on the Engel classification. Results Between different disease duration groups, the difference between the prognosis of the temporal surgery and the surgery of temporal lobe combined with other lobes was not statistically significant (Pgt;0.05), which indicated no relationship between the disease course and the prognosis. However, the difference between the prognosis of the surgeries outside the temporal lobe was statistically significant (Plt;0.05), which showed that patients with a longer disease course had a worse prognosis. Conclusion The prognosis of the epilepsy surgery outside the temporal lobe is correlated with the disease course. The shorter course has a better prognosis after surgery.
Objective To discuss the correlation between glutamate receptor 5 (GLUR5) and the pathogenesis of intractable temporal lobe epilepsy (ITLE), through detecting the GLUR5 expression in human with ITLE and Coriaria lactone-induced rhesus monkey temporal lobe epilepsy model. Methods Fifty-four patients with ITLE treated in West China Hospital between January 2007 and December 2015 were regarded as clinical case group in this study. The other 43 patients who underwent temporal lobe removal decompression surgery in the same time period due to trauma, tumor or large area cerebral hemorrhage complicated with cerebral hernia were designated as the clinical control group. Quantitive polymerase chain reaction (PCR) and Western blot methods were used to detect mRNA and protein levels of GLUR5. Western blot was also used to detect the GLUR5 protein level in the hippocampus and temporal lobe tissues of Coriaria lactone-induced rhesus monkey epilepsy model, and the result was compared with that of animal controls. Results Quantitive PCR results showed that the expression ratio (R value) of GLUR5 in the temporal lobe of the clinical case group to the clinical control group was 0.262, without significant difference (P>0.05), while theR value in the hippocampus was 4.896, with a significant difference (P<0.05). The amplification curve showed that the GLUR5 level in the hippocampus of the clinical case group was higher than that of the clinical control group, but the GLUR5 mRNA level in the temporal lobe tissue was not significantly changed. GLUR5 PCR amplified product electrophoresis showed that the amplified fragment was 161 bp. Western blot analysis showed that the GLUR5/actin value of the temporal lobe tissue in the clinical case group was 2.172±0.063, while the value in the clinical control group was 2.142±0.060, and the difference was not statistically significant (P>0.05). The GLUR5/actin value of the hippocampus in the clinial case group was 2.548±0.509, while it was 1.584±0.415 in the clinial control group, and the difference was statistically significant (P<0.05). The GLUR5/actin value of the hippocampus of the rhesus monkey model of epilepsy was 1.007±0.034, and it was 1.001±0.032 in the animal control group, and the difference was not statistically significant (P>0.05). The GLUR5/actin value of the temporal lobe tissue in the animal experimental group of rhesus model of epilepsy was 0.763±0.026, and it was 0.742±0.034 in the animal control group, and the difference was not statistically significant (P>0.05). The target protein bands showed that GLUR5 protein expression in the temporal lobe tissue and hippocampus of the rhesus model of epilepsy and animal controls was not significantly different (P>0.05). Conclusions GLUR5 participates in the pathogenesis of human ITLE by acting on the hippocampus. The expression of GLUR5 in human ITLE is abnormal, but the expression of GLUR5 is not changed in the rhesus model of epilepsy. The abnormal expression of GLUR5 may play a role in the pathogenesis of ITLE.
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。
