Objective To study the diversities of imaging, symptoms, electrophysiology and clinical value of the stereoelectroencephalography(SEEG) in patients with mesial temporal lobe epilepsy.Methods Eight patients with intractable epilepsy in Epilepsy Center of Yuquan Hospital of Tsinghua University who underwent mesial temporal lobectomy were recruited in this study, and their epileptic foci could not be accurately positioned.Therefore stereotactic brain electrodes were implanted, and their usual attack originated from mesial temporal lobe structure were confirmed.There was no seizure in the one year follow-up.Results Symptoms of the eight patients behaved differently, and the onset of the seizures in scalp electroencephalograph or SEEG showed diversities.Epileptic discharges were found originated from the mesial temporal lobe after implanting electrodes: in the early stage of discharges, four cases had the conduction to insular lobe structure;two cases had the conduction to contralateral mesial temporal lobe;one case had the conduction to retrosplenial cortex;one case had the conduction to parietal lobe;one case had the conduction to frontal lobe and rapid generalization (one case had the conduction to insular lobe and contralateral mesial temporal lobe meanwhile).Conclusions There is difference in clinic, imaging and electrophysiology of the patients with mesial temporal lobe epilepsy The non-specificity can be explained by the evolution of the intracranial electroencephalography, which can help us know its network conduction pattern Insular lobe is the most common conduction approach of mesial temporal lobe epilepsy in early stage SEEG can be used as a microinvasive, accurate preoperative localization method, which can help us to locate accurately and understand the discharges and conduction mode.

Objective To investigate the relationship between waist-to-height ratio and metabolic syndrome,in order to identify the optimal cut-off point of waist-to-height ratio for predicting metabolic syndrome.Methods In this cross-sectional study,we recruited 343 people who received physical examination in First Hospital of Quanzhou between January 2012 and June 2014,and collected the information of their waist circumference,height,weight,blood pressure,laboratory test results (including fasting blood glucose,2-hour glucose after oral glucose tolerance test,triglyceride,high-density lipoprotein cholesterol) and visceral fat area assessed by computed tomography.Then a receiver operating characteristic (ROC) curve analysis was used to estimate the optimal cut-off points of waist-to-height ratio for the prediction of metabolic syndrome.Results Among the 343 people,there were 195 metabolic syndrome patients,the prevalence rate was 56.8％,which was 70.2％ in men (127/181) and 42.0％ in women (68/162).In ROC curve analysis,the area under the curve of waist-to-height ratio for the prediction of metabolic syndrome was 0.664 for men,and 0.673 for women.The optimal cut-off point of waist-to-height ratio for predicting metabolic syndrome was 0.543 0 (sensitivity 88.2％,specificity 44.4％) for men,and 0.568 3 (sensitivity 86.8％,specificity 46.8％).Conclusion The optimal cut-off point of waist-to-height ratio for predicting metabolic syndrome in Quanzhou population is 0.543 0 for men and 0.568 3 for women.

Objective To propose a novel stereo-electroencephalography(SEEG) quantitative measure analyzing ictal high frequency (60-90 Hz) and calculating high frequency epileptogenicity index (HFEI) to localize epileptogenic zone and evaluate epileptogenic network. Methods The clinical presurgical evaluation and SEEG data of 15 patients who were performed SEEG electrodes implantation from April 2015 to March 2016 were analyzed retrospectively. Post-implantation head CT images and 3D MRI data were fused for accurately identifying and locating each electrode contact. Ictal SEEG quantitative measure HFEI was calculated and threshold was set. The epileptogenic network was divided into focal, regional, multiple regional and bilateral ones and the results were compared with the pathological results.Results The epileptogenic network was focal for four patients, regional for four patients, multiple regional for six patients and bilateral for one patient (7/15). In terms of the pathology,two cases with hippocampal sclerosis both showed regional network. In four cases with cerebral malacia, two cases showed multiple regional network and the other two cases showed focal network. In six cases with cortical malformation, three cases showed multiple regional network, the other three cases showed focal, regional and bilateral networks respectively. Conclusions We explored a novel SEEG quantitative measure based on the high frequency power analysis,which is objective and could localize epileptogenic zone and evaluate the epileptic network.

Objective:To analyze the characteristics of stereoelectroencephalography (SEEG) in children with drug-resistant epileptic spasms (ES), and to explore the surgical strategy of children with spastic seizure under the guidance of SEEG.Methods:The clinical data of 156 children with ES who were preoperatively evaluated in the Department of Neurosurgery Ward 3, Tsinghua University Yuquan Hospital from January 2014 to December 2021 were retrospectively reviewed.All children were evaluated in the second stage of stereotactic electrode placement after a non-invasive preoperative evaluation.The characteristics of intracranial EEG, surgical strategy and prognosis were analyzed.Results:A total of 19 eligible children were included, involving 13 boys and 6 girls.The age of first onset and surgical age of them ranged 1 month to 4 years, and 2 years to 13 years, respectively.The SEEG was divided into 3 types in children with ES at the onset.Five children were SEEG type A, presenting with the focal seizure discharges at the beginning and a gradual propagation to widespread fast-wave bursts.Ten children were SEEG type B, presenting a focal leading spike followed by diffused fast-wave bursts.Four children were SEEG type C, presenting a diffuse fast wave rhythm onset.Although some electrode discharges appeared slightly " leading", they covered more than one brain region.After focal resection or thermocoagulation, 13/19 patients did not have the onset of seizures, and 5/19 and 8/19 were graded as SEEG type A, and B, respectively.During the intermittent period of SEEG attacks in children with SEEG type A and B, a significant phenomenon of focal epileptic discharge consistent with the onset of the attack was observed, and surgical removal of these areas effectively controlled spastic seizures.Conclusions:Epileptic spasms may be triggered by a focal neocortical discharge.Intracranial EEG showed that the focal seizure onset evolves into spasm or a focal " leading spike" is a good indicator of surgical prognosis.

Objective:To investigate the effect of Fu-Fang-Yu-Jie(FFYJ)granules on LPS-induced inflammation model in bone marrow-derived macrophages(BMDM)and its intervention of FFYJ on nucleotide-bound oligomeric domain-like receptor protein 3(NLRP3)inflammatory signaling pathway in macrophages.Methods:Primary cells were extracted and isolated from the leg bone mar-row of C57BL/6 mice and BMDM macrophages were obtained after 7 days of induction with 50 ng/ml M-CSF.Groups included control group(Control),model group(LPS+ATP),FFYJ low dose group(FFYJ 50 μg/ml),FFYJ medium dose group(FFYJ 100 μg/ml),FFYJ high dose group(FFYJ 200 μg/ml)and positive drug dexamethasone group(DEX).BMDM in FFYJ treatment group and posi-tive drug group were pretreated for 1 hour before modeling.Lactate dehydrogenase(LDH)release assay was used to detect the level of LDH in the supernatant of each group of cells;ELISA was used to detect the level of inflammatory factors TNF-α,IL-6 and IL-1β in the supernatant of each group of cells;qRT-PCR was used to detect the levels of TNF-α,IL-6 and IL-1β in each group of cells;protein levels of NF-κB,p-NF-κB,NLRP3,Caspase-1 p45,Caspase-1 p20 and GSDMD-N in each group of cells were detected by Western blot;inverted fluorescence microscope was used to observe the cell pyroptosis of each group after Hoechst-PI staining.Results:Compared with control group,the levels of LDH,TNF-α,IL-6 and IL-1β in the supernatant of the model group were signifi-cantly higher(P<0.000 1);the mRNA levels of TNF-α,IL-6 and IL-1β in the model group were significantly higher(P<0.000 1);the protein levels of p-NF-κB,NLRP3,Caspase-1 p20 and GSDMD-N were significantly higher(P<0.05);and the number of PI-posi-tive cells was significantly higher(P<0.05).Compared with the model group,FFYJ and DEX significantly reduced the levels of LDH,TNF-α,IL-6 and IL-1β in the supernatant of BMDMs(P<0.05);down-regulated the mRNA levels of TNF-α,IL-6 and IL-1β in the cells(P<0.05);and inhibited the expressions of p-NF-κB,NLRP3,Caspase-1 p20 and GSDMD-N protein expressions(P<0.05);and significantly reduced the number of PI-positive cells(P<0.05).Conclusion:FFYJ exerts anti-inflammatory effects by inhibiting NLRP3 inflammasome activation in BMDM macrophages.

Objective:To find the chromosomal malfomations among microtia patients and the neighbouring genes of chromosomal aberrations or genes in the extra or deleted chromosome fragments would be screened to investigate the possible causative genes.Methods:According to the inclusion criteria, case group was selected from microtia patients referred to Plastic Surgery Hospital, Chinese Academy of Medical Science, between January 2012 and January 2014, and the control group was the normal people of similar age received plastic surgery in the same hospital in the same time who did not have any congenital genetic disease. Blood samples of two groups were collected, and genomic DNA was extracted, then copy number variation (CNV) analysis was performed in the two groups with gene chip technology and associated software for large fragment chromosomal malformations. The variations of chromosome copy number were recorded to further analyze the type and length of chromosome structure variation. The genes at the loci of break points were further screened referring to B allele frequency to interpret associated genes related to the occurrence of microtia. Fisher exact test were used for statistical analysis, and the difference was statistically significant ( P< 0.05). Results:942 patients with congenital microtia were included in the case group, 695 males and 247 females, aged (11.4±3.2) years; 1 802 normal controls, 1 290 males and 512 females, aged (11.6±4.9) years. Large chromosomal fragments variations were detected in 5 patients in chromosome in case group( P=0.003). The difference between the two groups was statistically significant( P=0.003). Three cases were found to carry an extra X chromosome. Among the 3 cases, one patient suffered from XXY karyotype and the other 2 patients X trisomy. Two cases were proved to be associated with chromosome structural variations. The malformations of the first case presented partial duplication of the long arm of chromosome 13 and 14. On searching for causative genes, OTX2, BMP4 and GSC were detected to be in the chromosome structural variations. The second case presented to be partial duplication of the long arm of chromosome 5. FGF pathway associated genes FGF18, FGFR4, FGF1 and BMP pathway associated genes FST, MSX2, SMAD5 were incorporated in the extra duplicated chromosome for possible gene dosage effect. Conclusions:The results indicated the possible association of chromosome abnormity and microtia and provide new insights in microtia-associated chromosome instability. Ten related genes were involved in the occurrence of microtia through various ways.

Objective:To study the localization value of stereoelectroencephalography (SEEG) in refractory epilepsy associated with tuberous sclerosis complex (TSC), and to analyze the prognosis related factors.Methods:A case control study.Data of 66 patients with TSC-related refractory epilepsy who underwent SEEG placement at the Epilepsy Center of Tsinghua University Yu-Quan Hospital from January 2014 to March 2023 were retrospectively analyzed, including medical history, seizure semiology, scalp electroencephalogram (EEG), imaging, and SEEG findings.Patients were divided into a seizure-free group and a seizure group according to the seizures after surgery. t/ χ2 test was used to compare the relationship between age of onset, age of surgery, duration of epilepsy, genetic findings, seizure symptoms, scalp EEG characteristics, SEEG placement protocol and prognosis. Results:A total of 66 patients met the enrollment criteria, of whom 55 patients were seizure-free after surgery (seizure-free group), and 11 patients still had seizures (seizure group).Among the 66 patients, there were 46 males and 20 females; the age of onset was (21.72±30.01) months; the age of SEEG surgery was (6.79±5.12) years; the duration of epilepsy was (4.98±4.11) years.SEEG results showed that seizures started with a single tuber in 43 patients (64.4%), seizures started with 2 or more tubers in one hemisphere in 16 patients, and 7 patients had bilateral multi-tubers or the pathogenic tuber(s) could not be identified.The following factors were found to be associated with prognosis: early age of surgery ( t=-3.463, P<0.01), ictal scalp EEG with a definite lateralization ( χ2=7.876, P<0.05), and the concordance of interictal and ictal EEG ( χ2=6.821, P<0.05).The age of onset, duration of epilepsy, seizure type and symptom, genetic findings, and SEEG placement protocol were not significantly correlated with prognosis.The results of SEEG identified that onset with a single tuber revealed a better postoperative outcome. Conclusions:This study confirms the safety and efficacy of SEEG in TSC-related refractory epilepsy, and also finds that ictal EEG is uniquely valuable in guiding SEEG placement for TSC-related refractory epilepsy, which can help us better select patients with TSC-related refractory epilepsy who are suitable for SEEG placement.
