Objective To study the seropositive ratio of the antibody to aquporin 4 (AQP4-IgG) and myelin oligodendrocytes glycoprotein antibody(MOG-IgG)in patients with autoimmune-associated central nervous system (CNS) diseases. Meanwhile, epidemiology and clinical manifestation and diagnosis,laboratory examination and magnetic resonance imaging(MRI)of AQP4-IgG seropositive and MOG-IgG seropositive patients are described. Methods 2068 patients serum samples were collected and enrolled in the multi-center research. The methodology of cell-mediated immunofluorescence staining was used to detect serum AQP4-IgG and MOG-IgG. Clinic medical records were collected and characteristics of epidemiology and manifestation were compared. Results 681 patients were AQP4-IgG seropositive and 110 patients were MOG-IgG seropositive. The female/male ratio and age of onset of patients with AQP4-IgG seropositive(616 female and 65 male,female:male=9.50:1.00;Age of onset=41.7±14.9)were significantly higher than that of patients with MOG-IgG (57 female and 53 male, female:male=1.08:1.00, P<0.0001; Age of onset=27.0 ±17.7, P<0.0001). The optic neuritis was significantly higher in patients with AQP4-IgG seropositive and patients with MOG-IgG seropositive (38.4% vs.53.5%, P<0.05).Among patients with AQP4-IgG seropositive, 42.14% conformed the diagnostic criteria of neuromyelitis optica (NMO),which was higher than that of patients with MOG-IgG seropositive (13.64%, P<0.0001). Laboratory examination showed that there was no significant difference in cerebrospinal fluid protein levels between patients with AQP4-IgG seropositive and those with MOG-IgG seropositive.MRI imaging suggested that AQP4-IgG positive patients were more common in cervical thoracic spinal cord lesions, while MOG-IgG positive patients were more involved in thoracolumbar spinal cord. The study also found that these two groups of patients could be comorbid with other autoimmune antibodies. Conclusions This multi-center research has revealed that patients with AQP4-IgG seropositive and those with MOG-IgG seropositive display differences in epidemiology,clinic manifestations and diagnosis,laboratory examination and MRI imaging. AQP4-IgG and MOG IgG auto-antibody detection are necessary for clinic diagnosis and differential diagnosis.

Objective:To investigate the predictive value of neutrophil/lymphocyte ratio (NLR) at admission for stroke associated pneumonia (SAP) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the First Affiliated Hospital of Kunming Medical University from January 2019 to June 2020 were retrospectively included. The demographic information, vascular risk factors, severity of stroke at admission, and NLR data of the patients were collected. Multivariate logistic regression was used to analyze the independent correlation between NLR and SAP. The NLR was divided into quartile groups to further analyze the trend relationship between NLR and SAP. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of NLR for SAP. Results:A total of 316 patients with AIS were enrolled, including 200 males (63.29%) with an age of 63.86±13.78 years. The median baseline Nationanl Institutes of Health Stroke Scale score was 4 (interquartile range, 2-9), and the median NLR was 4.42 (interquartile range, 3.17-6.70). Ninety-three patients (29.43%) experienced SAP. Multivariate logistic regression analysis showed that NLR was an independent risk factor for SAP in patients with AIS (odds ratio 1.189, 95% confidence interval 1.077-1.313; P<0.001). Moreover, SAP risk increases with the increase of NLR ( Ptrend<0.001). Compared to the first quartile, the risk of SAP increased 9.991 times in the fourth quartile (95% confidence interval 2.912-34.279; P<0.001). ROC curve analysis showed that the area under the curve of NLR for SAP prediction was 0.793 (95% confidence interval 0.737-0.850), with an optimal cutoff value of 5.475. The sensitivity and specificity for predicting SAP were 66.67% and 79.82%, respectively. Conclusion:NLR at admission is an independent risk factor for SAP in patients with AIS and has certain predictive value for SAP.

Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.
