Primary angiitis of the central nervous system is a rare and difficult entity. Here we represented the clinical and pathological features of a patient with little response to steroid before definite diagnosis. The 50-year-old male had a fluctuating disease course for more than 3 years. He presented visual disorders, seizure, cognitive impairment, hypersomnia, unsteady gait, dysphasia, dysphagia, and incontinence. Magnetic resonance imaging showed multiple, supratentorial and infratentorial abnormal signals, while cerebrospinal fluid and cerebral angiography were normal. Magnetic resonance spectrum showed a decrease of N-acetyl-aspartate. Brain biopsy revealed nongranulomatous lymphatic vasculitis with reactive gliosis, cicatrization, demyelination and focal hemorrhages.

BACKGROUNDTo investigate whether Borna disease virus (BDV) infection is related to the schizophrenic patients from China.
METHODSA reliable Western-blot method for detection of BDV-p24 antibody was established by adjusting the reaction conditions of BDV-p24 recombinant protein and specific antibodies. The sera of schizophrenic patients and normal controls from Heilongjiang Province were screened for specific BDV-p24 antibody by this method, and the BDV-p24 antibody positive sera were confirmed by the Western-blot method with sera-GST protein absorption.
RESULTSTen of 116 (8.6%) schizophrenic patients were found to be positive for BDV-p24 specific antibody, while no BDV-p24 specific antibody was found in sera of normal controls.
CONCLUSIONSThe results demonstrate that the Borna disease virus infection also exists in China, and the infection is possibly associated with schizophrenia in some way.

Objective To explore the clinical value of indocyanine green (ICG) fluorescence navigation combined with carbon nanoparticles (CNP) in sentinel lymph node biopsy (SLNB) for patients with early breast cancer. Methods A total of 294 early breast cancer patients with axillary node negative in Department of Breast Surgery, Foshan Hospital Affiliated to Sun Yat-Sen University from June 2013 to April 2016 were retrospectively analyzed. Of the patients, 149 cases underwent SLNB with ICG combined with CNP (combination group), while 145 cases underwent SLNB with methylene blue alone (MB group). If the intraoperative pathology results of sentinel lymph nodes (SLNs) were negative, axillary lymph node dissection (ALND) was avoided. The SLNs detection rate, detection number, metastatic SLNs detection rate in SLNB were compared between two groups. The influence of age and body mass index (BMI) on SLNs detection rate was also analyzed. Results In the combination group, subcutaneous lymphatic channels were successfully visualized in 145 patients, and the detection rate was 97.3%(145/149). The fluorescence of SLNs was successfully detected in 143 patients, and the detection rate was 95.9%(143/149). The detection rate of SLNs was higher in the combination group than that of methylene dye alone group (97.9%vs. 91.0%,χ2=6.902,P<0.05). The average number of detected SLNs was higher in the combination group than that of methylene dye alone group (4.5±1.6 vs. 3.2±1.5,t=4.476,P<0.05). Fifty-eight metastatic SLNs were found in 715 SLNs in the combination group (8.1%), and 26 in 544 SLNs in MB group (4.7%). The detection rate was significantly higher in the combination group than that of methylene dye alone group (χ2=13.714,P<0.01). Age and BMI showed no influence on the detection rate and accuracy of SLNB in two groups (P>0.05). Conclusion The combined tracing of ICG fluorescence and carbon nanoparticles for SLNB has showed a better stability and operability in patients with early breast cancer, which is recommended to be a new SLNB method.

Recent evidence indicates that the aberrant neuronal expression of mitotic proteins in Alzheimer's disease (AD) brain may be related to AD pathological changes. To investigate whether the toxicity of beta-amyloid protein (Abeta) induces mitotic proteins expression in adult rat brain, we used immunohistochemical and integral optical density analytic method to analyze the adult rat brains, which had been injected with Abeta(25-35) into unilateral amygdala. Results showed that the levels of neurofibrillary tangle (NFT) related phosphorylated tau protein and apoptosis related protein Bax were increased in Abeta(25-35) injected rat brains, meanwhile the aberrantly expression of mitotic protein cyclin A and cyclin B1 was also detected at 7 d after operation, but the level of cyclin A decreased and cyclin B1 disappeared at 21 d. Immunofluorescence double labeling presented that cyclin B1 was partially co-localized with Bax or phosphorylated tau protein, whereas Bax and phosphorylated tau protein seldom co-localized. These results suggest that Abeta causes mitotic protein expression in adult brain neurons, which may die through apoptosis or may be affected by AD NFT-related tau phosphorylation.

Ischemic stroke leads to high potentiality of mortality and disability.The current treatment for ischemic stroke is mainly focused on intravenous thrombolytic therapy.However,ischemia/reperfusion induces neuronal damage,which significantly influences the outcome of patients with ischemic stroke,and the exact mechanism implicated in ischemia/reperfusion injury remains unclear,although evidence shows that oxidative stress is likely to be involved.Betulinic acid is mainly known for its anti-tumor and anti-inflammatory activities.Our previous study showed that betulinic acid could decrease the reactive oxygen species (ROS) production by regulating the expression of NADPH oxidase.Thus,we hypothesized that betulinic acid may protect against brain ischemic injury in the animal model of stroke.Focal cerebral ischemia was achieved by using the standard intraluminal occlusion method and reperfusion enabled after 2 h ischemia.Neurological deficits were scored.Infarct size was determined with 2,3,5-triphenyltetrazolium chloride monohydrate (TTC) staining and the mRNA expression of NADPH oxidase 4 (NOX4) was determined by RT-PCR in infarct tissue.ROS generation and apoptosis in ischemic tissue were analyzed by measuring the oxidative conversion of cell permeable 2',7'-dichloro-fluorescein diacetate (DCF-DA) to fluorescent dichlorofluorescein (DCF) in fluorescence microplate reader and TUNEL assay,respectively.In Kunming mice,2 h of middle cerebral artery (MCA) occlusion followed by 24 or 72 h of reperfusion led to an enhanced NOX4 expression in the ischemic hemisphere.This was associated with elevated levels of ROS generation and neuronal apoptosis.Pre-treatment with betulinic acid (50 mg/kg/day for 7 days via gavage) prior to MCA occlusion prevented the ischemia/reperfusion-induced up-regulation of NOX4 and ROS production.In addition,treatment with betulinic acid could markedly blunt the ischemia/reperfusion-induced neuronal apoptosis.Finally,betulinic acid reduced infarct volume and ameliorated the neurological deficit in this stroke mouse model.Our results suggest that betulinic acid protects against cerebral ischemia/reperfusion injury in mice and the down-regulation of NOX4 may represent a mechanism contributing to this effect.
