Objective To evaluate the neuroradiological features of intraventricular central neurocytoma in ten patients.Methods Ten patients with central neurocytoma were imaged using contrast-enhanced and non-enhanced MRI scans,including 4 were also scanned with non-enhanced CT.The imaging data were studied with regard to location,size,margin,signal intensity,enhancement characteristics and presence of calcifications.Clinical data(i.e.presenting signs and symptoms,physical findings and medical history) were collected and histopathological and immunohistochemical studies were performed.Results There were 4 male,6 female in our group.All lesions were located in the lateral ventricles.Three tumors were confined to the left side,three to the right side and four involved both lateral ventricles.The growth of central neurocytoma was of close spatial relation to the septum pellucidum.In MRI,most of the cases showed a heterogeneous hypointensity on T1WI and hyperintensity on T2WI or FLAIR with a well-defined margin.The presence of cystic components,necroses and calcifications had been the cause of these internal heterogeneities.After intravenous administration of gadolinium(Gd-DTPA) all tumors showed a heterogeneous enhancement.CT provided additional information by distinguishing intratumoral calcifications in all four evaluated cases.Conclusion Central neurocytoma should be considered when young patients with lesions in the lateral ventricle,which contain calcifications and show some enhancement.This is especially applicable for tumors involving both lateral ventricles with symmetrical growth around the center of septum pellucidum or for unilateral ventricular tumors with a wide base attachment to the septum pellucidum.

Objective To explore the correlation between serum homocysteine (Hcy) level and diabetes mellitus combined with cerebral infarction (DMCI) in patients. Methods A total of 144 patients with type 2 diabetes mellitus (T2DM) were selected and divided into two groups, patients without cerebral infaction (group A, n=64) and patients with cerebral infaction (group B, n=80). Thirty healthy people were used as control group (group C). The serum Hcy level was detected by enzymatic cycling assay in three groups. The serum levels of cholesterol (TC) and triglyceride cholesterol (TG) were detected by enzymatic determination. The serum levels of high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected by homogeneous phase method. The serum level of creatinine (Cr) was detected by creatine oxidase method. The level of uric acid (UA) was detected by urinary enzyme peroxidase coupling method. Glycosylated hemoglobin (HbA1c) was detected by high performance liquid chromatography. The carotid artery intima media thickness (IMT) was examined by color Doppler ultrasound, and patients were divided into mild and no stenosis group, moderate stenosis group and severe stenosis group according to the
results. The levels of Hcy were compared between all groups. The correlation of Hcy level and other indicators was analyzed. Results The levels of Hcy and HbA1c were group C0.05). There were no significant differences in UA and Cr levels between the three groups (P>0.05). The level of Hcy was positively correlated with age (rs=0.411), HbA1c (rs=0.219) and Cr (rs=0.242), and negatively correlated with gender (rs=-0.202) and HDL-C (rs=-0.278, P<0.05). There were no significant correlation between Hcy level and other variables (P>0.05). With the increased degree of carotid artery stenosis, the Hcy level and the proportion of HHcy showed a rising trend in patients (P<0.01). The level of Hcy was positively correlated with IMT(rs=0.781, P<0.001). Conclusion Hcy is a risk factor for the onset of DMCI. The high level of Hcy is closely related to the occurrence and progression of atherosclerosis. Hcy has great value for early screening and prevention of DMCI.

Diabetic retinopathy (DR) is one of the most significant microvascular complications of diabetes,and its incidence increases with the prolongation of DM;meanwhile,it can lead to severe vision loss.Recently,the pathogenesis of DR has been one of the focuses both at home and abroad,but the basic mechanisms are not fully elucidated.More and more scholars believe that DR may be a chronic and low degree of inflammatory response.Moreover,it is well established that microglia is a monocyte-macrophage,with antigen-presenting function.Especially in the retina,as microglia is activated,followed by the release of a large number of inflammatory factors,microglia involves in DR inflammatory response.Understanding the activation mechanism of microglia can provide a new perspective for the prevention and treatment of DR.Therefore,recent advances in activation of microglia in diabetic retinopathy and its intervention mechanism will be reviewed in the article.

Objective Human amniotic mesenchymal stem cells (AM-MSCs) transplantation and to investigate the effect of propofol treatment, recovery of brain injury in rats. Methods 80 SD rats, male and female, weight 300-350 g. Human amniotic mesenchymal stem cells cultured in vitro and recovery (CM-Dil) before transplantation standby. The fluid percussion brain injury device, give 2.5-3.0 ATM hydraulic impact, severe fluid percussion brain injury model was made. After injury 6h give corresponding treatment which were randomly divided into 4 groups: injury group (medium injection group), AM-MSCs transplantation group and propofol group, AM-MSCs + propofol group. The number of positive cells in each group was observed under the fluorescence microscope using CM-Dil markers. 4 weeks after transplantation, 6 rats were randomly executed, and RT-PCR and Blot Western were used to detect the changes of GAP-43, AQP4 gene expression and protein synthesis in brain tissues. After transplantation, 24 h, 3 days and 1, 2, 3, 4 weeks for animal neurological deficit score, in 4 weeks after transplantation of Morris water maze (Morris Water Maze, MWM) test. They were killed after four weeks by immunohistochemistry, HE staining. Results Number of CM-DIL positive cell was the most in AM-MSCs + propofol group, which was in propofol group and AM-MSCs transplantation group were lower than that in the AM-MSCs + propofol group, which in injury group was the least, and the differences among the groups had statistically significant (P<0.05). 4 weeks after transplantation, AQP4 and its mRNA expression of brain damage surrounding tissue in injury group were higher than those in AM-MSCs transplantation group and propofol group; which in AM-MSCs transplantation group and propofol group was higher than those in AM-MSCs + propofol group (P< 0.05); GAP-43 protein and mRNA expression in injury group were lower than those in AM-MSCs transplantation group and propofol group, which in AM-MSCs transplantation group and propofol group were lower than those in AM-MSCs + propofol group (P<0.05). 1 weeks after transplantation, rat nerve dysfunction score in AM-MSCs + propofol group was lower than that in propofol group and AM-MSCs transplantation group; which in propofol group and AM-MSCs transplantation group was lower than that in the control group (P<0.05). The times of crossing platform in AM-MSCs + propofol group was higher than that in propofol group and AM-MSCs transplantation group, significantly higher than that in the injury group (P<0.01). The pathological section was observed 4 weeks after injury, there was no axonal passage in the injury group. In propofol group and AM-MSCs transplantation group, a few axonal like structures were observed, more axonal like structures were observed in AM-MSCs + propofol group. Conclusion Propofol combined with human amniotic mesenchymal stem cells transplantation can significantly improve the neurological function of rats with brain injury.
