Objective: To investigate the impact of stroke unit (SU) on the compliance of secondary prevention in patients with stroke at 12 months after stroke. Methods: Research subjects were stroke patients who were treated in SU (n = 500) and in general ward (GW) (n =445) using a design of retrospective study. The patients in the SU group were followed up by hospital, telephone and home interviews for 12 months, and the patients in the GW group were followed up by telephone interview for 12 months. The main outcome measures were the rate of using antithrombotics, the rate of smoking cessation, and the rates of awareness of early stroke symptom and stroke risk factors of patients. Results: he rate of using antithrombotics was 92.76% in the SU group, and it was significantly higher than 51.49% in the GW group (P ＜0.01); the rate of smoking cessation, and the rates of awareness of early stroke symptom and stroke risk factors of patients were 82.33%, 91.04%, and 94.03% respectively in the SU group, and they were significantly higher than 54.75%, 6.53%, and 70.37% in the GW group(P all ＜ 0.01 ). Conclusions: SU attaches importance to the secondary stroke prevention and emphasizes standardized treatment, and the compliance of the secondary stroke prevention in patient with stroke is improved significantly.

Objective To investigate the significance of the changes of brain natriuretic peptide (BNP) and D-dimer (DD) levels in patients with acute cerebral infarction with different etiological subtypes. Methods One hundred forty-six patients with acute cerebral infarction within 24 hours of onset were divided into four groups according to the TOAST classification:large-artery atherosclerosis (LAA, n =48), small-artery occlusion (SAO, n = 32), cardioembolism (CE, n = 41 ), and cryptogenic cerebral infarction (n = 25 ). Plasma BNP and DD levels were measured in the emergency department, and the correlation between both plasma BNP and DD levels and different subtypes of cerebral infarction, infarct rolume and severity of disease were analyzed. Results The plasma BNP and DD levels in the cardioembolism group were significantly higher than those in all the non-cardioembolism groups (all P ＜0.01). The plasma DD level was also increased significantly (compared to the LAA group, P ＜0. 05; compared to the SAO and cryptogenic cerebral infarction groups, all P ＜ 0. 01 ), while there were no significant differences in plasma BNP and DD levels among all the non-CE groups. The plasma BNP and DD levels in patients of the large infarction group were significantly higher than those of the moderate infarction group (t = 3.766 and 3.029, respectively; P = 0. 013 and 0. 029,respectively), and there was no significant difference between the moderate infarction group and the small infarction group (t= 1.275 and 1.207, respectively; P= 0.258 and 0. 281,respectively). The plasma BNP and DD levels in the National Institutes of Health Stroke Scale (NIHSS) score ≥ 7 group were significantly higher than those in the NIHSS score ＜ 7 group (t = - 3.454 and - 4. 044, respectively; P = 0. 018 and 0. 010, respectively). Conclusions Acute cerebral infarction, particularly the plasma BNP and DD levels were increased significartly in patients with cardioembolism, and the larger the infarct volume, the more serious the disease, and the higher the both levels. Early detection of plasma BNP and DD levels contribute to etiological classification of cerebral infarction, especially for the diagnosis of cardioembolism, as well as the identification of infarct volume and the severity of the disease.

Objective:Some antigens of M.tb to culture with peripheral blood mononuclear cells ( PBMC) for assaying their proliferation and activation,so as to signify whether lipid antigens of M.tb have specific immune responses in host against M.tb infection or not.Methods:We treated PBMC with several lipid antigens of M.tb to explore the ability of these antigens to activate immunity in healthy individuals.We measured and analyzed cell proliferation by labeling cells with carboxyfluorescein succinimidyl amino ester (CFSE) and subjecting them to flow cytometry (FCM).The production of IFN-γ,TNF-αand IL-4 by T cell subsets (NKT,CD4+, CD8+,andγδT) from healthy donors was analyzed by FCM after stimulation with autologous immature dendritic cells pre-cultured with M.tb lipid antigens.The tested M.tb lipid antigens were the total lipid (TLIP),Acetone-Soluble Lipids (ASLIP),Purified Sulfolipid (PSLIP),Lipoarabinomannan (LAM) and Lipomannan (LM) levels.Medium free of lipid antigens(WCL,CFP,LPS,Mtb-HAg and blank) was used as a control.Results:We found the proportion of proliferative NKT and CD8+T cells significantly increased in all lipid groups (P<0.05).ASLIP,LAM and LM promoted non-proliferative CD4+T cells to secrete IL-4 and proliferative ones to secrete IFN-γ( P<0.05).All lipid antigens promoted both proliferativeγδT cells and CD8+T cells to secrete IFN-γand TNF-α,but the proportion of TNF-α-secreting cells in these populations decreased in the LM group ( P<0.05 ).Conclusion: Lipid antigens may affect the CD1-restricted T cells of the host to fight M.tb infection.

Three myelin proteins, Nogo-A, MAG and OMgp, transduce their neurite-outgrowth inhibitory signal through a common receptor complex: NgR/ p75NTR (or TROY). Recently, LINGO-1 is identified as another essential component and regulator for the Nogo-66 receptor/p75 signaling complex. LINGO-1 is restricted to express in CNS, neuronal LINGO-1 is shown to be involved in the signal transduction from three myelin proteins, and Lingo-1 in oligodendrocyte negatively regulates the differentiation and myelination of oligodendrocyte. To investigate the potential activity of LINGO-1 in neuronal apoptosis, LINGO-1-Fc fusion protein including the extracellular LRR and IgC2 domain, was used as functional antagonist to study its protective effect on low-potassium induced apoptosis of cerebellar granule neurons (CGNs). In judgement of the apoptotic nuclei stained by Hoechst, LINGO-1-Fc pretreatment for 2 h significantly prevents apoptosis of CGNs. Although GST-LINGO-1 protein, including the LRR domain, binds to the CGN cultures in the same way with LINGO-1-Fc, it doesn't prevent the apoptosis of CGNs. These results indicate that LINGO-1-Fc fusion protein prevents low-potassium induced apoptosis of cerebellar granule neurons in certain conditions and this activity is probably IgC2 domain dependent.
