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 analyze the effect of precision filtration infusion apparatus and other methods on reduction of ADR induced by Acanthopanax injection. METHODS:532 patients receiving intravenous infusion of Acanthopanax injection were randomly divided into observation group and control group;observation group used disposable precision filtration infusion appara-tus,while control group used disposable ordinary infusion apparatus. The occurrence of ADR were compared between 2 groups. RE-SULTS:The incidence of ADR in observation group(2.68%)was significantly lower than in control group(7.75%),with statisti-cal significance(P<0.05). CONCLUSIONS:Intravenous infusion of Acanthopanax injection with disposable precision filtration in-fusion apparatus can effectively reduce the occurrence of ADR.
