Astragalus polysaccharide has been widely used in food and medicinal industry owing to its health-promoting properties. In order to characterize better the relationship among molecular weight, structure-activity and activities, a simple method was used different concentration of ethanol including 30% (PW30), 50% (PW50), 70% (PW70), 75% (PW75), 80% (PW80) and 90% (PW90) to precipitate Astragalus polysaccharides into different molecular weight. As a result, PW90 showed smooth surface and the strongest antioxidant activity among these six fractions (P < 0.05). In conclusion, graded ethanol precipitation was a simple method to separate Astragalus polysaccharides into different molecular weight with different antioxidant activity fractions.

?AlM: To investigate the expression of miR-181 in the lens tissue of cataract and the regulating mechanism of miR-181 on apoptosis of human lens epithelial cell.
?METHODS:Real time q-PCR was used to measure the expression of miR-181 in the anterior lens capsules of age - related cataract and human lens epithelial cell apoptosis model. miR- 181 mimic and inhibitor were transfected using Lipofectamine 2 000 to regulate the expression of miR-181, and then Real time q-PCR was used to verify transfection efficiency. Flow cytometry was used to detect the change of cell apoptosis rate.
? RESULTS: Compared with control group, the expression of miR-181 was significantly higher in both the anterior lens capsules of age-related cataract and human lens epithelial cell apoptosis model; the relative expression of miR-181 in lens epithelial cells transfected with miR-181 mimic was increased, whereas decreased in cells transfected with miR-181 inhibitor;the apoptosis rate of cells transfected with miR - 181 mimic was increased, while reduced in miR-181 inhibitor group. Each result was statistically significant (P<0. 01).
?CONCLUSlON:High expression of miR-181 is detected in anterior lens capsule of age-related cataract. miR-181 might play a certain role in the pathogenesis of cataract via promoting human lens epithelial cell apoptosis. miR-181 probably becomes a new approach for the nonoperative treatment of cataract, but the concrete mechanism still needs to be further studied.

To observe the protective effect and mechanism of Sailuotong capsule in focal cerebral ischemia/reperfusion. The 90 min middle cerebral artery occlusion (MCAO) reperfusion model was established. The expressions of dynamin-related protein 1 ( Drp1) and optic atrophy 1 (Opa1) were tested by Western blot. The transmission electron microscope was used to observe the changes in the mitochondrial ultra-structure. The pathological morphological changes were observed through the HE staining. The immunohistochemical method was used to test Drp1 and Opa1 expressions. Sailuotong capsule (33, 16.5 mg x kg(-1), ig) can inhibit the abnormal mitochondrial fission and fusion in the cortical area on the ischemia side and the mitochondrial fission gene expression and promote the mitochondrial fusion gene Opa1 expression, so as to alleviate the energy metabolism disorder caused by ischemia/reperfusion. Sailuotong capsule can inhibit the abnormal mitochondrial dynamics in peri-ischemic regions and maintain the normal morphology of mitochondria, which may be the mechanism of Sailuotong capsule in promoting the self-recovery function in the ischemic brain region.

Objective To investigate the incidence,pathogenetic factors,prognosis and correlation factors of acute kidney injury(AKI) in the hospitalized elderly patients. Methods The clinical data of 4781 elderly patients (aged 65 years and over) in our hospital from June 2008 to December 2009 were collected in this study using the hospital information system(HIS).The patients with AKI were picked out and were retrospectively analyzed. Results Among 4781patients,515cases (10.8％) suffered from AKI and the incidence of AKI increased with growing age. Single factorial analysis of etiology showed that infections (39.2％) was the most common causes of AKI.Multifactorial analysis revealed that the major causes of AKI were infections (81.0％),followed by hypovolemia (67.2 ％ ),nephrotoxic drugs (64.1％ ),cardiovascular diseases (32.3 ％),respiratory failure(17.7％) and neoplasm (9.5％). Multivariate logistic analysis and cox proportional hazard models indicated multiple organ dysfunction syndrome(MODS),gastrointestinal bleeding,mechanical ventilation and malnutrition were independent risk factors inducing end events such as dialysis or death and influencing time of live. Conclusions There is high incidence of AKI in the elderly hospitalized patient.Infections,hypovolemia,nephrotoxic drugs and cardiovascular diseases are the common causes of AKI.Active treatment of primary diseases,early diagnosis and prevention are beneficial for improving the prognosis of AKI.

OBJECTIVETo observe the protective effect of the Weinaokang (WNK) and its active compound bilobalide on focal cerebral ischemia reperfusion, and their mechanisms.

METHODThe 60-minute middle cerebral artery occlusion (MCAO) was adopted to establish the 24 h-14 d reperfusion model. The expression of Beclin-1 was detected by the Western blotting technique. The transmission electron microscopy was used to observe ultrastructural changes. Neurogenesis was detected by the immunofluorescence staining.

RESULTWNK (20, 10 mg x kg(-1), ig) or its active compound bilobalide (10, 5 mg x kg(-1), ig) could promote the generation of mature neurons (BrdU(+) -MAP-2+) at the ischemic side, and inhibit expression of autophagy-related gene Beclin-1, so as to reduce the neuron injury induced by focal cerebral ischemia reperfusion.

CONCLUSIONWNK and its active compound bilobalide can inhibit neuron autophagy and improve neurogenesis in ischemic peripheral area, suggesting that neurogenesis may be the intervention target for WNK to promote self-repairing of ischemic area.

Objective To understand the current situation of knowledge on healthy life style among researchers.Data on the knowledge of healthy life style including healthy behavior,general status on health,physical activity and the use of sports facilities were gathered.In 2006,same questionnaire was used to compare with the previous data.Results The percentage of overall knowledge on health among permanent percentage of people who were aware of knowledge on"no-smoking"."intake less salt","maintaining healthy diet program"and"insisting on exercise"were 72.97%,93.11%,86.58% and 87.25% respectively in 2006,higher than 67.38%,89.74%,82.12% and 82.78% during the baseline(P＜0.01)study in the previous years.The percentage of correct answer about the healthy life style as diet and prevention of common diseases was higher among the permanent residents than those of temporary residents in 2006(P＜0.05).The sources of health-related knowledge were mainly from media,newspapers and through health education programs carried out in the community.Conclusion The Beijing municipal government and the community residential committees attached great importance to providing knowledge on

Objective To investigate the diagnostic value of pregnancy-associated plasma protein-A (PAPP-A) in acute coronary syndrome (ACS) patients. Methods Forty-nine cTnI-negative patients with coronary artery disease who were documented by angiography [31 cases with ACS,18 cases with stable angina (SAP)], and 28 healthy persons were selected as controls. PAPP-A and hs-CRP were analysed with enzyme-linked immunosorbent assay (ELISA). Results Circulating PAPP-A and ha-CRP levels were significandy higher in patients with ACS than those in patients with SAP and controls (P < 0.05). PAPP-A threshold value of 2.79 μg/ml identified patients who had ACS with a sensitivity of 81.0% and a specificity of 84.6%. PAPP-A levels were correlated with hs-CRP levels in patients with ACS (r = 0.418, P < 0.01). Conclusion PAPP-A is a strong candidate marker of ACS, especially to eTnl-negative patients.

OBJECTIVETo measure the degree of satisfaction on various environmental and health components and to discuss the impact of Olympic Games among the residents so as to make relative policy suggestions.

METHODSIn 2006, permanent residents over 15 years old lived in the Asian Games Village Community (where the 29th Olympic Games to be held) were selected to conduct a household's survey, while 1610 valid questionnaires were collected. The questionnaire included demographic information, degrees of satisfaction on various health-related environmental components, living condition and on Olympic events.

RESULTSThe top 4 aspects with the highest satisfaction rates were "overall rates of satisfaction on current life" "green space", "housing conditions" and "water quality", which were 50.43%, 48.59%, 38.95%, 37.08%, respectively. Residents' satisfaction on "impact of hosting the Olympic Games on China's international image", "China's economic development level", "living conditions" and "personal life" were 65.53%, 56.09%, 47.27%, 46.40%, respectively. Data from partial correlation analysis showed that the total scores of satisfaction on environment and life had positive correlation with the total scores of Olympic satisfaction (P < 0.05). The satisfaction degree on Olympic event through factor analysis showed that 10 entries of the Olympic impact could be reflected by two factors--the influence of image to the nation and impact on personal income. Logistic regression showed that the impact of Olympic Games on personal income, the impact of Olympic Games on the image of the nation and standard of living, gender, education level were independent influencing factors of the total scores of environment and life satisfaction (P < 0.05).

CONCLUSIONOther than "green space", most of health-related environment components of Beijing had low degree of satisfaction among inhabitants from the 'typical' communities in Beijing. However, residents had a higher degree of satisfaction on the impact of the Olympic Games to the country's image, the country's economic development level, the environment and personal standard of living.
