Objective To compare the Poser and the McDonald diagnostic criteria for multiple sclerosis (MS).Methods Sixty-seven patients with clinical features suggestive of MS were re-evaluated by 2 neurologists utilizing both the Poser and the McDonald criteria.The Fisher' s exact test was used to statistically analyze the data from assessment by these two criteria.Results By the Poser criteria, 34 patients were classified as clinically definite MS, 24 patients as laboratory supported definite MS and 9 patients as possible MS.Under the new McDonald criteria, MS was diagnosed in 36 patients and 31 patients had possible MS.The results revealed significant differences in diagnosing MS between these 2 criteria (OR=5.549, 95% CI 2.37-13.00, P<0.01).Conclusions These 2 criteria showed remarkable differences in diagnosing MS, in particular definite MS, possibly due to greater reliance on paraclinical evidences in the Poser criteria and more stringent gnidlines of magnetic resonance imaging (MRI) in the McDonald criteria.The analysis of cerebrospinal fluid may increase the diagnostic rate of MS and specify pathologic abnormalities in MRI to some degree.

Objective To assess the clinical value of 131I-metaiodobenzylguanidine (MIBG) scintigraphy in pheochromocytoma. Methods A total of 430 patients with clinically suspected pheochromocytoma underwent 131I-MIBG whole body scintigraphy, 326 among them underwent B-ultrasound, 400 for CT and 77 for MR examination respectively. While 178 among them were diagnosed with pathology and the others were diagnosed clinically. Results Of all the patients, 108 were diagnosed pheochromocytoma, including 89 131I-MIBG scan positive and 19 negative. The sensitivity, specificity and accuracy of 131I-MIBG were 82.41%, 100% and 95.70%, respectively. 131I-MIBG scan detected 90.00% of unilateral adrenal, 45.45% of bilateral adrenal, 85.71% of ectopic and 66.67% of malignant lesions, respectively. The proportion of patients with positive 131I-MIBG scan increased from 20.69% in all patients to 35.15% in patients with clinical symptoms and positive conventional imaging (at least one of B-ultrasonography, CT or MR was positive) and 64.58% in those with clinical symptoms, positive conventional imaging, and elevated 24 h urinary catacholamines. In 59 patients with adrenal incidentaloma, 8 were scan-positive and all had confirmed pheochromocytoma, while 2 of scan-negative patients also had confirmed pheochromocytoma. Conclusion 131I-MIBG scintigraphy is the first choice for the diagnosis of both adrenal and extra-adrenal pheochromocytoma. However, it is inappropriate to take this method as the initial screening approach.

This paper assembled immunotherapy methods for neuromyelitis optica spectrum disorder (NMOSD) in recent years, including the treatment of acute stage, the prevention of relapse and the potential immunotherapy. The treatment of acute stage is mainly to inhibit inflammatory response and reduce aquaporin 4 (AQP4) antibody(Ab) titer, and this is done mainly by using high-dose hormone shock therapy and plasmapheresis. Remission treatment is to inhibit the proliferation of T cells and B cells and also remove B cells from the body, for the purpose of reducing the number of relapses. Azathioprine, rituximab and mycophenolate mofetil are mainly given during remission stage. The treatment of NMOSD will become more targeted/specific in the future. The mechanism of action of the new drug is mainly through blocking the binding of pathogenic AQP4-Ab and its antigen (Ag), reducing the generation of pathogenic AQP4-Ab, and blocking the downstream reaction after pathogenic Ab-Ag binding. The new drugs mainly include aquaporumab, tocilizumab, DNA vaccine, anti-CD19 monoclonal Ab (MEDI-551), eculizumab and bevacizumab.

The present study aimed to explore the neuroprotective effect and possible mechanisms of rhGLP-1 (7–36) against transient ischemia/reperfusion injuries induced by middle cerebral artery occlusion (MCAO) in type 2 diabetic rats. First, diabetic rats were established by a combination of a high-fat diet and low-dose streptozotocin (STZ) (30 mg/kg, intraperitoneally). Second, they were subjected to MCAO for 2 h, then treated with rhGLP-1 (7–36) (10, 20, 40 µg/kg i.p.) at the same time of reperfusion. In the following 3 days, they were injected with rhGLP-1 (7–36) at the same dose and route for three times each day. After 72 h, hypoglycemic effects were assessed by blood glucose changes, and neuroprotective effects were evaluated by neurological deficits, infarct volume and histomorphology. Mechanisms were investigated by detecting the distribution and expression of the nuclear factor erythroid-derived factor 2 related factor 2 (Nrf2) in ischemic brain tissue, the levels of phospho-PI3 kinase (PI3K)/PI3K ratio and heme-oxygenase-1 (HO-l), as well as the activities of superoxide dismutase (SOD) and the contents of malondialdehyde (MDA). Our results showed that rhGLP-1 (7–36) significantly reduced blood glucose and infarction volume, alleviated neurological deficits, enhanced the density of surviving neurons and vascular proliferation. The nuclear positive cells ratio and expression of Nrf2, the levels of P-PI3K/PI3K ratio and HO-l increased, the activities of SOD increased and the contents of MDA decreased. The current results indicated the protective effect of rhGLP-1 (7–36) in diabetic rats following MCAO/R that may be concerned with reducing blood glucose, up-regulating expression of Nrf2/HO-1 and increasing the activities of SOD.
