ABSTRACT

Objective To investigate the clinical characteristics,memory and neuroimaging features of nonlesional temporal lobe epilepsy (TLE-NL).Methods Forty-four patients with TLE-NL and 53 patients with unilateral temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) were recruited from the Second Affiliated Hospital of Zhejiang University from September 1st 2012 to August 31st 2017.The clinical characteristics were systematically analyzed and compared between TLE-NL and TLE-HS.Twenty healthy volunteers were also recruited.Memory assessment and high resolution magnetic resonance imaging(MRI) scanning were completed in the patients and healthy volunteers.Volume and shape of the hippocampus were compared between patients and healthy volunteers.Results Compared with the TLE-HS,TLE-NL patients showed later seizure onset ((24.3± 12.6) vs (15.8± 10.3) years;t=3.684,P<0.01),shorter duration of epilepsy ((4.00 (2.00,8.75)) vs (14.00 (7.50,22.00)) years;Z=-4.675,P<0.01),less history of febrile convulsions (4.5% (2/44) vs 62.3% (33/53);x2=32.270,P<0.01) and lower incidence of pharmacoresistant epilepsy (47.7% (21/44) vs 84.9% (45/53);x2=15.282,P<0.01).However,there were no statistically significant differences between TLE-NL and TLE-HS in sex ratio,family history of epilepsy,lateralization of the epileptogenic zone,presence of aura,seizure types and seizure frequency.TLE-NL patients had normal memory quotient compared to normal controls (105.2± 17.4 vs 103.8± 16.2;P=1.000),while TLE-HS patients had significant memory impairment compared to normal controls (84.5 ± 20.3 vs 103.8± 16.2;P<0.01).Compared to normal controls,TLE-NL patients did not have significant alteration in hippocampal volume and shape,while TLE-HS patients had significant atrophy in the ipsilateral hippocampus ((2 953±481) mm3vs (4 431±505) mm3;P<0.01),and shape analysis showed significant atrophy in the head and body of the hippocampus.Conclusion TLE-NL has different characteristics compared with TLE-HS,including later seizure onset,shorter duration of epilepsy,less history of febrile convulsions,better response to antiepileptic drugs,and no significant memory impairment and hippocampal atrophy.

ABSTRACT

Objective@#To investigate the clinical characteristics, memory and neuroimaging features of nonlesional temporal lobe epilepsy (TLE-NL).@*Methods@#Forty-four patients with TLE-NL and 53 patients with unilateral temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) were recruited from the Second Affiliated Hospital of Zhejiang University from September 1st 2012 to August 31st 2017. The clinical characteristics were systematically analyzed and compared between TLE-NL and TLE-HS. Twenty healthy volunteers were also recruited. Memory assessment and high resolution magnetic resonance imaging (MRI) scanning were completed in the patients and healthy volunteers. Volume and shape of the hippocampus were compared between patients and healthy volunteers.@*Results@#Compared with the TLE-HS, TLE-NL patients showed later seizure onset ((24.3±12.6) vs (15.8±10.3) years; t=3.684, P<0.01), shorter duration of epilepsy ((4.00 (2.00, 8.75)) vs (14.00 (7.50, 22.00)) years; Z=-4.675, P<0.01), less history of febrile convulsions (4.5% (2/44) vs 62.3% (33/53); χ2=32.270, P<0.01) and lower incidence of pharmacoresistant epilepsy (47.7% (21/44) vs 84.9% (45/53); χ2=15.282, P<0.01). However, there were no statistically significant differences between TLE-NL and TLE-HS in sex ratio, family history of epilepsy, lateralization of the epileptogenic zone, presence of aura, seizure types and seizure frequency. TLE-NL patients had normal memory quotient compared to normal controls (105.2±17.4 vs 103.8±16.2; P=1.000), while TLE-HS patients had significant memory impairment compared to normal controls (84.5±20.3 vs 103.8±16.2; P<0.01). Compared to normal controls, TLE-NL patients did not have significant alteration in hippocampal volume and shape, while TLE-HS patients had significant atrophy in the ipsilateral hippocampus ((2 953±481) mm3 vs (4 431±505) mm3; P<0.01), and shape analysis showed significant atrophy in the head and body of the hippocampus.@*Conclusion@#TLE-NL has different characteristics compared with TLE-HS, including later seizure onset, shorter duration of epilepsy, less history of febrile convulsions, better response to antiepileptic drugs, and no significant memory impairment and hippocampal atrophy.

ABSTRACT

Objective To study the role of P53 target gene TIGAR on proliferation ,migration and invasion of lung cancer cells . Methods siRNA was introduced to knock down TIGAR in A 549 cells .Proliferation was detected by CCK-8 .The ability of migra-tion and invasion was measured by and ,respectively .was used to evaluate the expression levels of related proteins .Results Knock-down of TIGAR reduced the proliferation rate (P< 0 .05) ,inhibited the ability of migration and invasion ,decreased expression levels of MMP-2 and MM P-9 .Conclusion TIGAR promotes proliferation ,migration and invasiveness of lung cancer cells .
