Abstract
Objective: To investigate the surgical efficacy of neurosurgery robot deep brain stimulation(DBS) in the treatment of elderly Parkinson's disease(PD). Methods: The clinical data of elderly patients (≥75 years) with PD who underwent neurosurgical robot-assisted DBS surgery in the Department of Neurosurgery of the General Hospital of Northern Theater Command from September 2016 to September 2022 were collected retrospectively. Operation time, electrode implantation duration, postoperative pneumocephalus volume, electrode implantation accuracy, the Tao's DBS surgery scale, perioperative complications were analyzed.The unified Parkinson's disease rating scales (UPDRS), UPDRS-Ⅲ, tremor, rigidity, bradykinesia, axial, Barthel Activities of Daily Living (ADL-Barthel), Levodopa Equivalent Daily Dose (LEDD), Montreal Cognitive Assessment (MoCA), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) scores and mortality were assessed respectively before operation, 6, 12 and 24 months after operation and last follow-up. Results: A total of 25 elderly patients were enrolled, including 14 males and 11 females, aged(78.3±3.2) years. Nine patients had underlying diseases. Nine patients (36%) underwent bilateral Globus Pallidus pars Interna deep brain stimulation (GPi-DBS) and 16 patients (64%) underwent bilateral subthalamic nucleus deep brain stimulation (STN-DBS).The operation time was (1.56±0.19) hours, the electrode implantation duration was (1.01±0.19) hours, the pneumocephalus volume was 9.8(4.7, 23.3) cm3, and the electrode implantation accuracy was (0.84±0.24) mm, the Tao's DBS surgery scale was (80.2±6.2).The follow-up time [M(Q1, Q3)] was 57.3(27.9, 75.7) months. No serious complications such as intracranial hemorrhage, infection or poor wound healing occurred during the perioperative period. The improvement rate of UPDRS, UPDRS-Ⅲ, rigidity, bradykinesia, and LEDD at 6 months after surgery was significantly higher than that at 24 months after surgery and at the last follow-up (all P<0.05); the improvement rate of axial symptoms, ADL-Barthel score, and MoCA score at 6 months after surgery was significantly higher than that at the last follow-up (P<0.05). HAMD and HAMA scores showed no significant improvement during follow-up after surgery (both P>0.05). At the last follow-up, 12 patients died, with death time of (35.1±20.2) months after operation, and the death age of [M(Q1, Q3)] 80(79, 83)years. Conclusions: Robot-assisted DBS surgery for elderly patients with PD is accurate and safe, and the postoperative symptoms are significantly improved, and they can benefit from neuromodulation for long term, and the risks are controllable.

Abstract
Objective: To explore the clinical effect of Woven EndoBridge (WEB) in the treatment of wide-neck bifurcation aneurysms. Methods: The clinical and imaging data of 11 patients with intracranial wide-neck bifurcation aneurysms treated by WEB alone at Department of Neurosurgery of the Northern Theater General Hospital from September 2017 to May 2018, were retrospectively analyzed. The patients were 7 males and 4 females, aged (54±11) years (ranged from 31 to 66 years). The aneurysms of 5 patients were located in the anterior communicating artery, 3 in the top of the basilar artery, and 3 in the bifurcation of the middle cerebral artery. The intraoperative and postoperative conditions of the patients were recorded, and the degree of aneurysm embolization was evaluated by WEB embolization aneurysm occlusion scale (WOS). Results: The intraoperative WEB release of all the 11 patients was good, with 3 cases of WOS grade A, 1 of grade B and 7 of grade C, with no intraoperative acute complications occurring. The imaging follow-up was not carried out in 1 patient due to economic reason, and the clinical follow-up was good until 3 years after the operation; 10 patients were followed up by imaging for 6 months to 3 years, and no postoperative complications occurred in the target treatment area. Among the 2 patients with WOS grade A and 1 patient with grade B during operation, according to the postoperative follow-up, all were WOS grade A; among the 7 patients with WOS grade C during operation, 4 were still of grade C and 3 were of grade D according to the follow-up. Among the 3 patients with WOS grade D, 1 patient received secondary embolization due to poor recurrence morphology, unstable hemodynamics and high possibility of rupture of aneurysm, stent assisted coil embolization was adopted, with good immediate effect; the other 2 cases had recurrent aneurysms, but the aneurysms had good morphology and stable hemodynamics, therefore, clinical follow-up was continued and no secondary surgery was performed. No complications occurred in all these 11 patients. Conclusions: The operation of treating unruptured intracranial wide-neck bifurcation aneurysms with WEB device alone is simple, and there is no need for anticoagulation and antiplatelet treatment before and after the operation, the clinical effect is being good. WEB device provides a new treatment option for intracranial wide-neck bifurcation aneurysms.

Abstract
Objective: To investigate the efficacy and safety of different stents assisted embolization in the treatment of subarachnoid hemorrhage(SAH) caused by V4 dissecting aneurysm of vertebral artery. Methods: The clinical data of 39 patients with spontaneous SAH V4 dissecting aneurysm treated at the Department of Neurosurgery, the Northern Theater General Hospital from January 2016 to June 2019 were analyzed retrospectively.There were 21 males and 18 females, aged (48±17) years(range:35 to 68 years).There were 24 cases of HUNT-HESS grade Ⅰ and 15 cases of grade Ⅱ.Among them, 20 cases were treated with single stent-assisted embolization, 9 cases with multi-stent-assisted embolization, 9 cases with semi-dense mesh-assisted embolization, and 1 case with dense-mesh stent-assisted embolization.The perioperative and postoperative complications, postoperative recurrence were collected. Results: Intraoperative complications included 2 cases of aneurysm rupture and 2 cases of acute thrombosis.All aneurysms were densely packed according to the angiography performed immediately after operation.Postoperative complications included 3 cases of long-term responsible vascular ischemia(modified Rankin score<2). The patients were followed up for 15.1 months(range: 12 to 29 months). At the last follow-up, aneurysms recurrence occured in 10 cases, the recurrence rate was 25.6%(10/39). There were 6 cases of recurrence and 2 cases of complications in 20 cases with single stent-assisted embolization, 3 cases of recurrence and 4 cases of complications in 9 cases with multi-stent-assisted embolization, 1 case of recurrence and 1 case of complications in 9 cases with semi-dense mesh stent. Conclusion: Endovascular treatment is feasible for patients with vertebral artery dissecting aneurysm, and the appropriate surgical method should be selected according to the vascular structure and the location of the aneurysm.

Abstract
OBJECTIVE To study pathogenesis of astrocytes in the SD model. METHOD The male adult SD rats were divided into 3 groups at random with 10 for each group to study pathologic changes and dysfunctions of astrocytes in the model with 3 weeks and 6 weeks of observation time. RESULTS Compared with the control group and the 3w O+D group, the incubation period for the rats of the 6w O+D group to reach the platform is significantly prolonged in the water maze behavioral experiment; the times of passing through the platform and the duration for staying in the target quadrant are significantly decreased but there is no statistical difference between the control group and the 3w O+D group; compared with rats of the control group and the 3w O+D group, the rats of the 6w O+D group show signs of significant density decrease and AChE activity decrease of cholinergic fiber terminals in the hippocampal region, but there is no statistical difference between the control group and the 3w O+D group; compared with control group, the GFAP level of in the hippocampal region of the rats of the 3w O+D group and the 6 w O+D group significantly increases but there is no statistical difference between the two groups; the hippocampi and some areas of the cerebral cortices of the rats of the 6w O+D group show signs of HRP leakage in the peripheral region of blood vessels. However, HRP reaction products of the control group are distributed within the blood vessels and show no signs of significant leakage. CONCLUSION OVX combined with injection of D-gal can serve as a good animal model simulating AD disease. Astrocytes play an important role in occurrence and progression of pathological changes of the model (Tab. 6, Fig. 6, Ref. 30).

Abstract
The association between the microsomal epoxide hydrolase 1 gene (EPHX1) Tyr113His polymorphism and lung cancer and breast cancer risk has been reported in many recent studies, but there is no consensus among the results. Thus, we examined the association between the EPHX1 Tyr113His polymorphism and lung cancer through a meta-analysis. A comprehensive literature search was performed using the Pubmed and Embase databases. Odds ratios with 95% confidence intervals were used to assess the strength of associations. Our meta-analysis suggested that the Tyr113His polymorphism was associated with lung cancer risk in Asians under 3 genetic models, including a C vs T, CC vs TT, and recessive model. However, the risk was decreased in Caucasians under the genetic models, including a C vs T, CC vs TT, or CT vs TT, dominant, and recessive model. In contrast, there was no association with breast cancer risk for any of the genetic models. Our meta-analysis suggested that the EPHX1 Tyr113His polymorphism may be a risk factor for lung cancer in Asians, whereas it may be a decreased risk factor among Caucasians. However, this polymorphism was not found to be associated with breast cancer.

Abstract
Benzyl and phenoxymethylene substituted oxadiazoles are potent and orally bioavailable beta3 adrenergic receptor (AR) agonists. The 4-trifluormethoxy substituted 5-benzyl oxadiazole 5f has an EC50 of 8 nM in the beta3 AR agonist assay with 100-fold selectivity over beta1 and beta2 AR binding inhibition activity. Its oral bioavailability in dogs is 30 +/- 4%, with a half-life of 3.8 +/- 0.4 h. In the anesthetized rhesus, 5f evoked a dose-dependent glycerolemia (ED50Gly = 0.15 mg/kg). Under these conditions a heart rate increase of 15% was observed at a dose level of 10 mg/kg.

Abstract
We have examined intramolecular hydrogen bonding in four homologous compounds, N-acetyl-, N-propionyl-, N-i-butyryl-, and N-pivaloyl-proline-methylamide, in methylene chloride, by means of 1H-nmr and ir measurements. At room temperature, the major trans conformer of MeCO-Pro-NHMe appears to be approximately 68% intramolecularly hydrogen bonded, the trans conformers of EtCO-Pro-NHMe and i-PrCO-Pro-NHMe are approximately 75% intramolecularly hydrogen bonded, and t-BuCO-Pro-NHMe is approximately 50% intramolecularly hydrogen bonded. Thus, the internally hydrogen-bonded state (C7 or gamma-turn) is significantly less populated for the N-pivaloyl compound than for the other three molecules in this series. Variable temperature measurements indicate that for each proline derivative there is very little enthalpic difference between the intramolecularly hydrogen-bonded and nonhydrogen bonded states of the trans rotamer. Changing the N-terminal acyl group also affects intramolecular hydrogen bonding (including beta-turn formation) in end-blocked Pro-Gly dipeptides.
