Objective To set up a method for determination of the trace amounts of aluminium(Ⅲ) in water samples. Methods Second derivative polarogaphy was used. Results In a solution of acetate buffer(HOAc-NH4OH, pH=5.8), Al(Ⅲ)reacted with Berllon Ⅲ to form a complex and a sensitive polarogaphic adsorptive wave appeared at -0.54 V(vs.SCE). By using the 2nd derivative polarogaphy measyrement, the wave height had a linear relationship with the concentration of Al(Ⅲ)in the range of 0.005-0.300 ?g/ml. The limit of detection was 3.0 ng/ml. RSDs were 5.4%-9.1%. Recovery rates were 92.7%-108.0%. Conclusion The present method is sensitive, accurate with high selectivity and can be applied to the determination of the trace amounts of Aluminium(Ⅲ) in water sample with satisfactory results.

Objective To know the TCM discipline development situation through analysis on TCM articles based on Chinese Science Citation Database (CSCD) in recent years. Methods Articles about TCM in CSCD from January 2010 to December 2015 were searched by computers. The CSCD literature analysis system was used to conduct metrological analysis from the aspects of publishing time, source journals, cited information, authors, publishing organizations, research themes, and fund support. Results The number of articles published on CSCD was increasing year by year from January 2010 to December 2015. 85.09% of articles focused on the field of general medicine. There were more than 100 CSCD journals included in TCM professional articles. 17 journals published more than 100 TCM professional articles. WANG Yong-yan academician was the author who published the most articles (121 papers). Academic output H index of six authors was more than 5. 31.52% articles in CSCD were cited. Natural Science Foundation of China (including general and youth projects) funded the highest number of articles (12.2%), reaching 1716 articles. Conclusion Analysis on articles from CSCD can outline the development situation of TCM discipline in China. In recent years, the number of TCM articles is increasing; subject integration is good; high-level teams are forming gradually; TCM discipline is developing fast. However, the citation frequency is low; scholar H index is not high; the overall level remains to be improved.

icating that Fas/FasL plays an impertant role in the regulation of immune/inflammation response in the CNS, and such role does not depend on the apoptotic pathway, This article reviews its progress in research on the inflammatory response in the CNS.

indicators of oxidative stress.

The changes of immune system following stroke mainly includes the local inflammatory responses of brain tissue and the systemic immunological changes, The former may exacerbate brain damage following stroke, the latter may increase the susceptibility to infection, and thus impact on brain function recovery and prognosis. Stroke interferes with the normal balance between the nervous system and the immune system, and its mechanism remains unclear. This article reviews the stroke-indnced immunological alterations and their mechanisms,as well as the corresponding treatment strategies in clinical practice.

Sirtuin is a type of deacetylase acted on histone. Sirtuin 1 (SIRT1) is the most homologous to the homologue of silent information regulator 2 (SIR2) in mammals. Its main function is to regulate the body energy metabolism, cell senescence and response to stress. SIRTI inhibits apoptosis through the interaction of several transcription factors involving in stress response. It is a neuroprotective gent.

At present, ischemie stroke is one of the main diseases of the highest mortality and disability in the world. However, the traditional treatment methods (for example, thrombolytic therapy) have some disadvantages, such as narrow time window, and poor efficacy. As a cell therapy, cord blood stem cell transplantation has brought hope to the treatment of refractory nervous system diseases.

High mobility group protein box 1 (HMGB1) is a typical nonhistone chromosomal protein. It has many celular functions in nucleus. Studies in recent years have showed that HMGB1 can be released to the outside of cels to exert a wide range of cytological effects. Ischemic stroke is one of the diseases with the highest morbidity and disability. More and more evidence has shown that HMGB1 plays a variety of important roles in the occurrence and development process of ischemic stroke. This article reviews the roles of HMGB1 in ischemic stroke.

Oxidative stress phys a very important role in the cerebral ischemia-reperfusion injury.The role of NADPH oxidases (NOX) in oxidative stress after ischemic stroke has been paid more attention and may become a new therapeutic target.This article sums up the major research progress between NOX and cerebral ischemia-reperfusion injury,discusses the characteristics of various isozymes and their relationship with stroke,further investigates the pathogenesis of stroke from the perspective of NOX,and provides a new idea for the prevention and treatment of ischemic stroke.

Mesenchymal stem cells (MSCs) play a neuroproteetive effect via a variety of mechanisms.They provide a new idea for the treatment of cerebral ischemia.However,the inadequate sources have significantly limited the possible clinical applications.Carbon nanotubes (CNTs),a new nanomaterials,can not only promote the adhesion,proliferation and differentiation of MSCs in vitro,but also as the cell carriers they can provide good microenvironmental guarantee for the survival of MSCs through the regulation of secretion of cytokines and neurotrophic factors,as well as regulation of biological characteristics of neurons,glial cells,and macrophages after their cell transplantation,provide a good microenvironment guarantee for the survival of MSCs,and promote the effect of MSCs on the therapeutic effect of cerebral ischemia.
