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.

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.

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.

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.

Objective To explore the influences of parent-child attachment security memory activation on college students'general attachment working model. Methods 152 college students were randomly distributed to three groups, among which there were two experimental groups accepting father-child or mother-child memory activation,and one control group accepting non-interpersonal memory activation. Results Mather-child security memory activation significantly increased subjects' scores on others-model of general attachment to females (F= 3.83;P ＜0.05), scores of mather-child security memory activation group were significantly higher than those of fatherchild group ( 7.88 ± 7.24,4.49 ± 7.53; P ＜ 0.05 ) and control group ( 7.88 ± 7.24,4.71 ± 6.83; P ＜ 0.05 ).Father-child security memory activation significantly increased subjects' scores on self-model of general attachment to males (F= 6.35; P ＜ 0.01 ), scores of father-child security memory activation group were significantly higher than that of mather-child group (6.33 ±5.39,2.44 ±6.14; P＜0.01 ) and control group (6.33 ± 5.39,2.59 ±6.10; P ＜ 0.01 ). Conclusion Parent-child attachment security memory activation have major influences on college students' general attachment working model, in which the effect of gender differences provides some inspiration for clinical interferences.

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.

Thrombolytic therapy is a main treatment method for ischemic stroke.Intravenous recombinant tissue-type plasminogen activator (rtPA) is the only FDA-approved therapy for acute stroke; however,its clinical application has been limited because the narrow therapeutic time window and the presence of the risk of hemorrhagic complication.In order solve these problems,a large number of clinical trials have started to focus on the studies of intra-arterial thrombolysis,mechanical thrombolysis and sonothrombolysis.

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.
