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.

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.

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.

Cascade in cerebral ischemic injury may cause cholinergic dysfunction,inflammation and oxidative stress. It plays an important role in the pathological processes of vascular dementia. A large amount of basic research has confirmed that cholinesterase inhibitor and N-methyl-d-aspartate receptor inhibitor may improve cognitive function in patients with vascular dementia. However, the efficacy of these drugs has been confirmed in only a part of the patients, and their safety and efficiency have not achieved the expected results. Thus, it needs further study and exploration.

ObjectiveTo investigate the effects of alpha-lipoic acid on serum soluble intercellular adhesion molecule-1 (sICAM-1) and high sensitive-C reactive protein (hs-CRP) levels in patients with early diabetic nephropathy (DN).MethodsA total of 61 patients with early DN were randomized into treatment group (n =31 ) and control group ( n =30 ).The two groups were both treated with dietary control and oral hypoglycemic drugs or insulin.Meanwhile,the treatment group was additionally given alpha-lipoic acid 300 mg/d by intravenous infusion for 20 days.The levels of sICAM-1 and hs-CRP in each group were detected.Results The levels of sICAM-1 and hs-CRP were decreased significantly in alpha-lipoic acid treatment group after 20 days of therapy ( [ 198.03 ±23.67] μg/L vs [271.17 ±34.66] μg/L,[5.16 ±0.43] mg/Lvs [7.95 ±0.88]mg/L,P ＜0.01 ).Conclusion alpha-lipoic acid may decrease the expression of slCAM-1 and hs-CRP,and that may be one of the mechanisms to postpone the progress of early DN.

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.

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.

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
