Abstract
Retrospective analysis was conducted on 9 patients with type Ⅱ focal cortical dysplasia (FCD) who underwent stereo-electroencephalography (SEEG) implantation in the Department of Neurosurgery of the First Affiliated Hospital of Fujian Medical University from November 2020 to February 2023. The onset area, onset time, and frequency of high-frequency oscillations (HFO) were analyzed and the correlation of HFOs with interictal, preictal, and ictal periods. SEEG recordings of 80-500 Hz HFOs were observed in both interictal and ictal periods in 9 patients, with 6 patients exhibiting fast ripples (FR) in the range of 250-500 Hz. Surgical resection of the seizure onset area and FR-generating electrodes was performed, and postoperative follow-up for over 2 years indicated Engel I in 5 cases. 6 patients showed continuous discharge during the preictal period, and the distribution index of continuous discharge was positively correlated with seizure frequency. HFOs in the range of 80-500 Hz were present in all four seizure onset patterns during the ictal period. The onset area and FR-emitting electrode were surgically removed in 6 patients with continuous discharge and overlapping HFOs during the preictal period, with 5 cases of Engel I. Type Ⅱ FCD discharges exhibited complexity, high discharge indices, and a close association with HFOs. Compared with the spike wave, the electrode range of HF is more limited, and the incidence of HF before attack is significantly increased, which is closely correlated with the onset area. The simultaneous occurrence of HFO and the spike waves has higher diagnostic value than the individual occurrence, effectively enhancing surgical efficacy.

Abstract
The clinical and pathological features and postoperative outcomes of 49 patients with diffuse low-grade glioma -related epilepsy who were admitted to the Department of Neurosurgery of the First Affiliated Hospital of Fujian Medical University from January 2015 to December 2018 were analyzed. After 1-year follow-up, 33 patients (67.3%) in the good prognosis group and 16 patients (32.7%) in the poor prognosis group were enrolled. Multivariate logistic regression analysis indicatedthat subtotal tumor resection (OR=5.56, 95%CI:1.21-25.44,P=0.027) and no postoperative radiotherapy (OR=9.24, 95%CI:2.05-41.75, P=0.004) were the risk factors for poor prognosis of postoperative epilepsy. Therefore, for patients with diffuse low-grade glioma-related epilepsy, total tumor resection and postoperative radiotherapy are beneficial to the control of epilepsy.

Abstract
Objective: Percutaneous radiofrequency thermocoagulation (RFT) of the Gasserian ganglion is an effective treatment for refractory trigeminal craniofacial pain.In the present study, we assessed the feasibility of accessing the Gasserian ganglion through the foramen ovale with neuronavigation guidance in the patients of trigeminal craniofacial pain. Method: We retrospectively analyzed forty-four patients with type Ⅰ trigeminal neuralgia who had undergone percutaneous RFT treatment in our hospital from June 2014 to December 2016.The patients were divided into fluoroscopy group and navigation group according to the intraoperative guiding manners for foramen ovale cannulation.We compared groups in terms of the duration of the whole RFT procedure and times of intraoperative fluoroscopy.We also analyzed the immediate and late outcome accessing by Barrow Neurological Institute (BNI) pain scale, as well as the complication rates in groups. Result: There were 32 patients in the fluoroscopy group and 12 in the navigation group.The duration of the surgical procedure in navigation group was less than that in fluoroscopy group (46±12 min versus 67±16 min, P=0.00), and times of intraoperative fluoroscopy was reduced (6.3±2.2 versus 1.3±1.6, P=0.00). The learning curve of navigation-aid RFT was not steep in the present study overall.There was no significant difference between groups regarding pain reduction at the immediate (P=0.07) or late follow-up (P=0.400) time points.However, the rate of pain reduction to BNI-Ⅰ grade was greater in navigation group (P=0.026). No significant difference in the complication rate between both groups, and no serious complications were observed in the both groups. Conclusion: Neuronavigation may be encouraged in trigeminal Gasserian ganglion RFT with better operating efficiency and less radiation exposure.The immediate and late therapeutic effects for craniofacial pain control were positive, whereas further studies are necessary.

Abstract
Glioblastoma multiforme (GBM-WHO grade IV) is the most common and the most aggressive form of brain tumors in adults with the median survival of 10-12 months. The diagnostic detection of extracellular matrix (ECM) component in the tumour microenvironment is of prognostic value. In this paper, the fibrillar collagen deposition associated with vascular elements in GBM were investigated in the fresh specimens and unstained histological slices by using multiphoton microscopy (MPM) based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG). Our study revealed the existence of fibrillar collagen deposition in the adventitia of remodelled large blood vessels and in glomeruloid vascular structures in GBM. The degree of fibrillar collagen deposition can be quantitatively evaluated by measuring the adventitial thickness of blood vessels or calculating the ratio of SHG pixel to the whole pixel of glomeruloid vascular structure in MPM images. These results indicated that MPM can not only be employed to perform a retrospective study in unstained histological slices but also has the potential to apply for in vivo brain imaging to understand correlations between malignancy of gliomas and fibrillar collagen deposition.

Abstract
OBJECTIVE To explore the relevant factors associated with the surgical efficacy and prognosis of seizures in patients with low-grade glioma (LGG). METHODS The clinical cases of seizures in patients with LGG admitted to our department were retrospectively collected from January 2010 to December 2014. A total of 45 cases were studied to analyze the relevant factors associated with the surgical efficacy and prognosis. RESULTS During a follow-up period of 1 to 5 years after surgery, Engel classⅠ to Ⅱ were achieved in 36 patients (80%) and Engel class Ⅲ to Ⅳ in 9 cases (20%). The preoperative epilepsy frequency and the use of intraoperative electrocardiograph (ECoG) were correlated with the surgical efficacy and prognosis (P<0.05). The other factors, such as age, gender, duration of epilepsy, and tumor characteristics, had no significant statistical difference. CONCLUSIONS The surgical efficacy of seizures in patients with LGG is favorable. Our results suggest that preoperative epilepsy frequency and intraoperative ECoG are important factors for surgical efficacy and prognosis. Consequently, based on gross total resection for seizures in patients with LGG, epileptogenic zones should be considered and dealt with by use of ECoG.
