Abstract
Objective: To evaluate the related factors of postoperative recurrence intrigeminal neuralgia (TN) patients treated with fully neuroendoscopic microvascular decompression (MVD). Methods: The clinical baseline data and preoperative MRI imaging data of 112 patients with TN treated by neuroendoscopic MVD from December 2008 to December 2020 in the Department of Neurosurgery, Beijing Shijitan Hospital Affiliated to Capital Medical University were retrospectively analyzed, including: area ratio of cerebellopontine area (CPA)(healthy side/affected side), trigeminal nerve(TGN)length ratio(healthy side/affected side), TGN angle ratio(healthy side/affected side), and criminal vessel type. Multivariate Cox proportional hazards model was used to analyze the factors affecting postoperative recurrence. Results: Among the 112 patients in this group, there were 49 males and 63 females. The age ranged from 20 to 82 (59±9) years, and the course of disease was 0.05 to 30.00 (5.60±5.15) years. Pain was located on the left side in 43 cases (38.39%) and on the right side in 69 cases (61.61%), respectively. All patients were followed up for more than 1 year, with an average follow-up time of 21.5 months, and 11 cases recurred. Multivariate Cox regression analysis revealed that disease duration≥3 years(HR=9.34, 95%CI:1.12-39.07), CPA area ratio(healthy side/affected side)>1 (HR=27.47, 95%CI:1.69-44.20), criminal vessel type with vein(HR=35.39, 95%CI:1.26-18.60) and criminal vessel type with arteriovenous (HR=46.07, 95%CI: 2.74-27.75) were the main factors influencing recurrence of MVD surgery (all P<0.05). Conclusion: The disease duration≥3 years, CPA area ratio(healthy side/affected side)>1, and criminal vessel type with vein/arteriovenous are the relevant factors that affect the recurrence rate after the fully neuroendoscopic MVD treatment for trigeminal neuralgia.

Abstract
Objective: To explore the efficacy and technical features of fully endoscopic microvascular decompression(MVD) in primary trigeminal neuralgia(PTN) via keyhole approach. Methods: The clinical data of 97 patients with PTN underwent fully endoscopic MVD via keyhole approach in the Department of Neurosurgery, Beijing Shijitan Hospital, Capital Medical University from December 2014 to February 2019 was collected. During fully endoscopic MVD in PTN via keyhole approach, performer use natural clearance without grinding except developed rock bone crest or excessive retraction of the brain tissue, visually and panoramically observe and evaluate the CPA area, accurately identify the responsible vessels, to avoid the omission of responsible vessels or insufficient decompression. And the use of preplaced technology, bridging technology and submersible technology, ensure the efficacy of surgery and reduce the surgical side injuries.Barrow Neurological Institute (BNI) pain score was used to evaluate the efficacy and identify the recurrence. The surgical efficacy was analyzed. Results: The offending vessels were identified under endoscope in 96 cases. Among them, arterial compression was found in 77 cases, venous compression in 6 cases, and both arterial and venous compression in 13 cases. About the pain outcomes, 87 cases had immediate and complete relief of pain, 5 cases had almost relief of pain, 4 cases had partial relief of pain, and still needed medication control, but the dose was lower than that before operation, and 1 case had no obvious relief of pain. About complications, there were 4 cases of temporary facial numbness, 1 case of temporary hearing loss, both of them recovered after symptomatic treatment. There was no cerebral infarction or hemorrhage, intracranial or incision infection. All cases were followed up for 3.0-38.0 months with a median period of(22.4±2.2) months. During the follow-up periods, postoperative recurrence occurred in 3 cases. Conclusion: Fully endoscopic MVD for PTN through keyhole approach, provides panoramic view to avoid omission of offending vessels and reduce complications, seemed to be a safe and effective surgical method.

Abstract
OBJECTIVE miRNAs have been confirmed to be related to cell proliferation and apoptosis. In this study, we detected the potential effect of miR-448 on glioma cell proliferation and apoptosis. MATERIALS AND METHODS miR-448 and CTTN expression levels were detected in glioma cell lines with quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Cells were transfected with miR-448 mimics and inhibitor by using lipofectamine 2000 respectively. The proliferative ability of transfected cells was detected via methyl thiazolyl tetrazolium (MTT) and cell counting kit-8 (CCK8) assays. Cell apoptosis and cell-cycle were tested using flow cytometry. The regulatory correlation between miR-448 and CTTN was explored by bioinformatics analysis and luciferase reporter assay. RESULTS Lower expression of miR-448 and higher level of CTTN were detected in glioma cells. MiR-448 could regulate cell proliferation, cell apoptosis, and cell cycle. CTTN was negatively regulated by miR-448. CONCLUSIONS miR-448 downregulates CTTN to inhibit cell proliferation and promote apoptosis in glioma, which indicates a potential therapeutic target of glioma.

Abstract
Objective: To study the operative method, special technique and curative effect of complete neuroendoscopic microvascular decompression(MVD) related to vertebrobasilar artery compression. Methods: Thirteen patients with functional cranial nerve disease caused by vertebrobasilar artery as direct or indirect responsible vessel accepted complete endoscopic MVD, including 11 patients with hemifacial spasm and 2 patients with trigeminal neuralgia. The procedure and curative effect of endoscopic surgery were analyzed retrospectively. Results: All procedures of complete neuroendoscopic MVD were successfully completed.Intraoperative observation by endoscope showed that 6 cases were oppressed directly by vertebral artery, 2 cases were oppressed directly by basilar artery, 5 cases were combined oppressed by displaced basilar artery and other vessels (1 case was superior cerebellar artery and 4 cases were anterior inferior cerebellar artery). During the operation, Teflon sheets was placed directly into the compression point in 2 cases, the "Pre-placed" technique was used to place Teflon sheets in 7 cases, and the "Set up bridge" technique was used to place Teflon sheets in 4 cases. Follow-up for 8-38 months,the symptoms disappeared completely in 12 cases and improved in 1 case. No deaths and severe complications occurred, such as postoperative bleeding, cerebellar infarction and intracranial infection. Conclusion: MVD related to vertebrobasilar artery compression can be performed by complete neuroendoscopic technique, which can achieve sufficient decompression effect and curative effect.Flexible use of the special technology of placing Teflon sheets by single-hand under endoscope, such as the "Pre-placed" and "Set up bridge" technique, is an important technical guarantee for the successful completion of endoscopic MVD.

Abstract
Objective: To investigate the efficacy of soft neuroendoscopic techniques in the treatment of chronic subdural hematoma (CSDH). Methods: A retrospective analysis of 201 cases of CSDH diagnosed and treated at Beijing Shijitan Hospital (CMU) from January 2006 to December 2017 was conducted. From January 2006 to December 2010, 126 cases of CSDH were treated with skull drilling and drainage (non-endoscopic group). From January 2011 to December 2017, 75 cases of CSDH were treated with soft neuroendoscopy (endoscopic group). The operation time of the non-endoscopic and endoscopic groups, the hematoma clearance rate on the first day after surgery, the time of the drainage tube, the length of hospital stay, the incidence of complications, mortality and recurrence rate were compared. Results: There were no deaths in both groups. The average operation time of the non-endoscopic group was 43 min, compared with the average operation time of the endoscopy group of 50 min, there was no significant difference (P>0.05). The average hematoma clearance rate on the first day after surgery in the endoscopy group (98.2%) was significantly higher than that in non-endoscopic group (87.3%) (P<0.01). The average time of drainage tube in the endoscopy group (23 h) was significantly shorter than that in the non-endoscopic group (50 h) (P<0.01). On the first postoperative day, the proportion of patients with mRS≤3 in the endoscopic group was significantly higher than that in the non-endoscopic group (P<0.01). At the time of discharge, the proportion of patients with mRS≤3 in the endoscopy group was also significantly higher than that in the non-endoscopic group, P<0.05. There was no significant difference in the average hospital stay between endoscopy group (7 d) and non-endoscopic group (8 d) (P>0.05). The postoperative complication rate in the endoscopy group was significantly lower than that in the non-endoscopic group (P<0.01). During 0.5-8 years of follow-up, the recurrence rate of CSDH in the endoscopic group (5.33%) was significantly lower than that in the non-endoscopic group (15.07%) (P<0.01). Conclusion: The application of visualization features of soft neuroendoscopy in the treatment of CSDH can significantly improve hematoma clearance, shorten the time of drainage tube, reduce postoperative complications and recurrence rate, and improve surgical outcomes.
