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.

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.

Carotid stenosis is one of the important causes of cerebral infarction. It has been demonstrated that carotid angioplasty and stenting (CAS) can prevent the occurrence of stroke, and its clinical application is continuously increasing. Although CAS is a microinvasive technique, it has some potential complications, such as hemodynamic abnormalities, hyperperfusion syndrome, cerebral infarction, and restenosis. This article reviews the complications of CAS and their management strategies.

Thrombolytic therapy for ischemic stroke has received wide attention. Now the thrombolytic therapy mainly includes intervenous thrombolysis, intra-arterial thrombolysis, combination of intravenous and intra-arterial thrombolysis, and mechanical thrombolysis. The review mainly presents the recent progress in this field.

Cognitive impairment caused by ischemic stroke is becoming more and more concerned.It is crucial to explore its pathophysiological mechanism and related clinical predictive indexes for understanding the occurrence,development and treatment of the disease.This article discusses the pathophysiologic mechanism of cognitive impairment after stroke from the aspects of white matter damage,amyloid abnormal deposition,blood-brain barrier damage,and synaptic plasticity injury,and reviews the risk factors,imaging and biological markers that can be used to predict cognitive impairment after stroke.

Cerebral small vessel disease (CSVD) refers to the syndromes of clinical,cognitive,radiographic and pathological manifestations caused by intracranial small vessel disease.Due to the insidious onset of CSVD,unknown etiology,diverse clinical manifestations,and better short-term prognosis,it is easily ignored,resulting in misdiagnosis,missed diagnosis,and non-standard diagnosis and treatment.This article reviews the advances in research on clinical manifestations,imaging features,diagnosis and treatment of CSVD.

Ischemic stroke is one of the diseases with the highest morbidity and disability.Hypertension is recognized as the most important independent risk factor for ischemic stroke.Vascular remodeling during the development of hypertension is the pathological basis of causing ischemic stroke.Studies have shown that vascular smooth muscle cell proliferation and apoptosis will lead to vascular remodeling.In addition,cerebral ischemia-reperfusion can result in neuronal damage and apoptosis.Recent research has shown that vascular remodeling and neuronal apoptosis are associated with chloride channels.At least 3 chloride channels including volume regulated chloride channel,calcium activated chloride channel and cystic fibrosis transmembrane conductance regulator are involved in these processes.This article reviews the roles of the 3 chloride channels in vascular remodeling,neuronal apoptosis,and ischemic stroke.

Cerebral small vessel disease (CSVD) refers to a group of pathological processes caused by various causes that affect the microarteries,small arteries,venules and capillaries in brain tissue.Inflammation and endothelial dysfunction may play an important role in mechanism of leading to CSVD-related changes.The research in related fields is expected to become an important means of in-depth understanding of CSVD.The driving factors of brain dysfunction caused by CSVD and the relative role of vascular lesions and primary neurodegenerative changes in the process of CSVD remain unclear.The examinations reflecting cerebrospinal fluid components of the central nervous system degenerative lesions and vascular lesion process can provide important information.The related biochemical changes may become an early identification indicator of CSVD,at the same time it can enhance the understanding of its characteristic mechanism.In addition,CSVD specific biomarkers can also play an important role in monitoring the therapeutic effects.

Cerebral small vessel disease (CSVD) is an important cause of functional incapacitation,disability,and cognitive impairment in the elderly.Subcortical CSVD can lead to lacunar infarcts and progressive white matter lesions.CSVD cognitive impairment is an important subtype of vascular cognitive impairment (VCI).The dementia caused by it accounts for about 36%-67% of vascular dementia.With the development of technology,neuroimaging and its related markers has become a powerful tool for the diagnosis of CSVD and cognitive impairment.The clues of the CSVD pathogenesis can also be found in the field of brain cognition.STandards for ReportIng Vascular changes on nEuroimaging (STRIVE) has established the neuroimaging markers of 6 critical damages,including recent small subcortical infarcts,lacunar foci that are assumed to be the origin of blood vessels,white matter hyperintensities that are assumed to be the origin of blood vessels,perivascular spaces,cerebral microbleeds,and brain atrophy.This article reviews the correlation between VCI caused by CSVD and imaging features.

Objective To investigate the estrogen receptor expression character on neurons and glial cells of rat at different ages. Methods Brain sections from normal and injured rats of different ages were chosen to observe the ER immunohistochemistry reaction in cerebrum. Results To compare with normal young rat group,the neurons in hippocampus dentate gyrus of normal aged rat group expressed much less estrogen receptors.There were many ER-positive glial cells appearing in hippocampus of brain injured was rat group,and the positive strain of young injured was much stronger than that of aged rat group.Conclusion The decrease of ER on neurons in dentate gyrus makes the aged more apt to neurodegeneration.The young rats may better utilize the neuroprotection of estrogen against injuries by increasing the amount of ER on glial cells.
