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.

Membrane-associated guanylate kinases (MAGUKs) is a class of postsynaptic density proteins (PSDs) in the postsynaptic dense of the postsynaptic membrane,including PSD-95,SAP-102,PSD-93,and SAP-97.MAGUK family members contain several protein binding sites,and these special binding sites are responsible for mediating a variety of signal transduction.MAGUKs participate in the occurrence and development mechanisms in central nervous system diseases,and has become a topic of general interest of neuroscience.This article briefly reviews the roles of MAGUKs in ischemic brain injury.

Apolipoprotein E (ApoE) has gene polymorphism (ε2,ε3,and ε4).It has been confirmed that ApoE structural and functional abnormlities are closely associated with the hyperlipidemia,formation of atherosclerosis,and its severity,while both hyperlipidemia and atherosclerosis are the risk factors for ischemic stroke.In recent years,although the relationship between the ApoE gene polymorphism and ischemic stroke has been extensively studied,the conclusions are not consistent.This article reviews the correlation studies between the ApoE gene polymorphism and ischernic stroke.

Cerebral small vessel disease (SVD) is an important subtype of cerebrovascular disease. It is also one of the major reasons for resulting in vascular cognitive impairment or dementia in the elderly. SVD is a small arteriovenous lesion in subcortex caused by a variety of causes, mainly causing subcortical lacunar infarction, white matter damage, microblecds and other pathological changes. There is evidence that vascular endothelial function and blood-brain barrier damage may result in small vessel structures and perivascular changes, which may be the initial factors.of causing SVD. Genetic susceptibility is also one of the risk factors that can not be ignored.

Immuno-inflammation is one of the main pathophysiological mechanisms of ischemic brain injury,of which chemokines and its receptors widely participate in the occurrence and development processes of ischemic brain injury.Interleukin-8 (IL-8) and its receptors participate in the activation and chemotaxis of neutrophils into brain tissue,and may further aggravate cerebral ischemia-reperfusion injury.At present,therapeutic drugs for IL-8 are mainly CXC chemokine receptor 2 antagonists,including narrow and broad-spectrum chemokine antagonists.This article reviews the advances in research on the pathological mechanism and targeting treatment of IL-8 in ischemic brain injury.

Angiogenesis is one of the effective strategies for the treatment of ischemic cerebrovascular disease, and a variety of angiogenic factors and antiangiogenic factors involved in the process of regulation. Apelin is a newly discovered peptide, ari it is the endogenous ligand of G protein-coupled receptor APJ (Angiotensin Ⅱ Type 1 Receptor-Associated Protein). Apelin and APJ express widely in rat and human hearts and brains, etc. Apelin-APJ system has a role in promoting angiogenesis. It has an important significance in the treatment of ischemic diseases. This article review the mechanisms of action and advances in angiogenesis of apelin-APJ system.

The patients with stroke is often accompanied by malnutrition, its causes include eating less, increased catabolism, and intestinal dysfunction, etc. Malnutrition can not only aggravate the extent of brain damage in patients with stroke, but also increase the incidence of complications, and thus affecting the course and prognosis of stroke. Therefore, correct evaluation of the nutritional status in stroke patients, choosing the appropriate nutrient timing and nutritional support methods have important significance. Among a variety of nutritional assessment methods, the scored Patient-Generated Subjective Global Assessment can quickly identify malnutrition in stroke patients. Early enteral nutrition support, including oral nutritional supplements, nasogastric tube feeding and percutaneous endoscopic gastrostomy, can significantly improve the prognosis in stroke patients. Among them, nasogastric tube feeding is the first choice for nutritional support in stroke patients.

Objective To study the expression and diagnostic value of p27 and CD44V6 in ovarian carcinomas.Methods 54 cases of ovarian carcinoma were examined by immunohistochemical two-step-system method for p27 and CD44V6.Results The positive rates of p27 and CD44V6 is 37.0 %(20/54),42.6 %(23/54) respectively.The positive rates of p27 is 20.0 %,12.0 % and 8.7 % in clinic stage Ⅲ~Ⅳ,poorly differentiated tumors and lymphnode metastasis group compared with 68.4 %,58.6 % and 58.1 % in clinic stageⅠ~Ⅱ,well differentiated tumors and lymphnode negative group(P

Objective To study the expression and clinical significance of p16 and p27kip1 in endometrial carcinoma. Methods 65 cases of endometrial carcinoma were examined by immunohistochemical method for p16 and p27kip1. Results The positive rates of p16 and p27kip1 was 47.7 % and 41.5 % respectively. Both the expression of p16 and the expression of p27kip1 were correlated with histologic differentiation. Conclusions p16 and p27kip1 may play important roles in the development of endometrial carcinoma. They were important in predicting the prognosis and directing the treatment of endometrial carcinoma.
