BACKGROUND: As a kind of unwounded biomagnetism technique, magnetoencephalography (MEG) relfects immediate information of cerebral function by using magnetic source imaging through recording changes of magnetic field of neurocytes under different functional status.OBJECTIVE: To investigate the practicability of magnetoencephalography (MEG) imaging in localizing sensory-motor cortex for brain tumour surgery in 36 patients.DESIGN: Observational study.SETTING: Department of Neurosurgery, Guangdong Provincial Hospital of Traditional Chinese Medicine.PARTICTPANTS: From Janury 2003 to April 2006, 36 patients (17 male and 19 female) with brain tumors selected from Deparment of Neurosurgery, Guangdong 999 Brain Hospital underwent surgery with MEG-guided neuronavigation in the region of the sensory and motor cortex. Ages of the patients ranged from 13 to 70 years. Among the 36 patients, 14 with gliomas (including 5 highly malignant gliomas), 19 with meningomas, 1 with spongy angioma and 2 with adenocarcinoma (due to the metastasis of brain tumor). All patients and relatives provided the confirmed consent and the experiment provided by the local ethics committee.METHODS: A 148-channel biomagnetometer (4-D Neuroimaging, USA) was used to determine motor and/or senory cortex with sampling rate 678.17 Hz, high-pass filter 1.0 Hz and bandwith 200 Hz. MRI images were acquired using a Philips Gyroscan Intera 1.5T MR tomography. And then, the functional maps were transfered to the neuronavigation system for the treatment of brain tumor. All patietns followed up by further consultation and telephone call in 2-26 months after operation.MAIN OUTCOME MEASURES : Operative outcome and prognosis.RESULTS: MEG demonstrated that the tumor lesion changed the sensory-motor cortex in various degrees for the 36 patients. Brain tumors were resected completely in 34 cases. At 2-26 months after surgery, neurological deficits fully recovered in 19 cases, unchanged in 15 cases and deteriorated in 2 cases.CONCLUSION: MEG was found to be practical and useful in localizing sensory-motor cortex and brain tumor. It is a valuable non-invasive method for presurgical planning in the treatment of brain tumors.

Objective To investigate the clinical value of von Willebrand factor antigen-to-albumin ratio (VAR) score and glycocalicin index (GCI) score in predicting the development and classification of esophageal varices in comparison with von Willebrand factor antigen-to-platelet ratio (VITRO) score. Methods A retrospective analysis was performed for 146 patients with hepatitis B cirrhosis who were hospitalized from April 2020 to December 2021, and esophageal varices (EV) was diagnosed and graded with the results of gastroscopy as the standard. VITRO, VAR, and GCI were calculated, and their association with EV was analyzed. The t -test was used for comparison of normally distributed continuous data between two groups, and a one-way analysis of variance was used for comparison between multiple groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test was used for comparison of categorical data between groups. A logistic regression model analysis was used to identify the predictive factors for EV, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic accuracy of each index. Results Gastroscopy showed 54 patients without EV, 30 with mild EV, 33 with moderate EV, and 29 with severe EV. The patients with EV had significantly higher VAR and GCI scores than those without EV ( t =-5.819 and -3.449, both P < 0.001). The linear regression analysis showed that VAR and GCI increased with the increase in EV grade ( P =0.002 and 0.005). The multivariate logistic regression analysis showed that VAR (odds ratio [ OR ]=1.46, 95% confidence interval [ CI ]: 1.21-1.75, P < 0.001) and GCI ( OR =1.84, 95% CI : 1.22-2.77, P =0.003) were independently associated with EV. VITRO score had an area under the ROC curve (AUC) of 0.718 in diagnosing EV and 0.863 in diagnosing severe EV, with the optimal cut-off values of 2.77 and 5.37, respectively. VAR and GCI had an AUC of 0.745 and 0.710, respectively, in diagnosing EV, with the optimal cut-off values of 8.88 and 1.70, respectively; VAR and GCI had an AUC of 0.755 and 0.787, respectively, in diagnosing severe EV, with the optimal cut-off values of 9.81 and 2.00, respectively. VAR combined with GCI had significantly better efficacy than VITRO in diagnosing EV ( P =0.009), with an AUC of 0.808, a sensitivity of 55.43%, and a specificity of 94.44%; VAR combined with GCI had an AUC of 0.869 in diagnosing severe EV, which was similar to VITRO ( P =0.421). Conclusion VAR and GCI scores are potential noninvasive markers for the prediction and risk stratification of EV in patients with hepatitis B cirrhosis.
